The grammar's `file` rule gets one arm per literal, and the version line alone picks the regime.\n- The new arm reads declarations with an id (header_decl, item_decl, grouped_item) and references as id_ref. id_token is spelled with ranges (improvise-rxz9). axis_line is tried before format_line (improvise-le4p).\n- The old arm is read exactly as today: whole-line headers, references resolved against displays, ids assigned by slugify, and undeclared items declared at load (answer 24).\n- The loader refuses a new-version file with a duplicate id, a missing id, an id outside the alphabet or a reserved `_` id. The error names the line, and for a duplicate it names both lines.\n- The writer always writes the new literal, and pipe-quotes any display that would otherwise split (`## Category: |Region(code)|(regioncode)`, improvise-80rm).\n- The round-trip properties from clause 5, plus a formula-line generator strategy (improvise-rxz9), so the formula properties are not vacuous.\n\nThe formula-line syntax waits for improvise-m56i.\n\n## Acceptance Criteria\n- Tests first, each failing before the change:\n  - an old file with `## Category: Region(code)` loads with display `Region(code)` and id `regioncode`, and its data stays drawn;\n  - a new-version file keeps every id verbatim, including `east-3`;\n  - duplicate, missing and capitalised ids are each refused with the line named;\n  - a category displayed `Format` on a row axis round-trips;\n  - format(parse(format(parse(x)))) == format(parse(x)) holds.\n- Evidence that the formula strategy emits `=` lines the walker keeps: count them.\n","status":"open","priority":1,"issue_type":"task","owner":"el-github@elangley.org","created_at":"2026-09-25T04:49:41Z","created_by":"agent-adr007","updated_at":"2026-09-25T04:49:41Z","dependencies":[{"issue_id":"improvise-cq1q.5","depends_on_id":"improvise-cq1q","type":"parent-child","created_at":"2026-09-25T04:49:41Z","created_by":"agent-adr007","metadata":"{}"},{"issue_id":"improvise-cq1q.5","depends_on_id":"improvise-cq1q.1","type":"blocks","created_at":"2026-09-25T04:50:54Z","created_by":"agent-adr007","metadata":"{}"},{"issue_id":"improvise-cq1q.5","depends_on_id":"improvise-cq1q.4","type":"blocks","created_at":"2026-09-25T04:50:53Z","created_by":"agent-adr007","metadata":"{}"}],"dependency_count":2,"dependent_count":1,"comment_count":0}

Wire operands are already keys, via cq1q.7, which now lands first. Added acceptance criteria: (1) a document with categories displayed Region and Café, and item East, survives save and load at this step with every display intact. The rival, a writer that writes keys, gives region/caf/east and fails.

This is pre-existing: the reviewer's scratch lockstep gives identical results at gh/main 202e7eac, at #277 aab62a36 and at #282 6942e53e. #282 fixed this exact aliasing in `declined_at` only (improvise-y5eb), with the new `projected_at`, which reads through `AxisFrame::first`.\n\n`resolve::cell_at_cursor` (and `cell_at`/`seed_at`) index `GridCache` with the view's cursor offsets. The client folds its own scroll (SetRowOffset/SetColOffset) at once, but the cache keeps the old window until the host answers. Any key resolved in that gap reads a different cell from the one under the cursor. That includes `edit_or_drill` (`i`), `commit` (its `id`, and `record_at_cursor` for the write's target) and the seed.\n\nWorst case, a silent write to the wrong record. Fixture: `_Measure` rows [Revenue, Profit (explicit item + `Profit = Revenue - Cost`), Cost], Month [Jan, Feb] on columns, every cell stored. Client window (2 rows, 1 col), cursor at (0,0). Keys `$`, `i`, `7`, `Enter` are all folded and sent before any reply is delivered:\n- TUI: Feb/Revenue = 107.\n- Host, fed the client's frames: **Jan/Revenue = 107**, and Feb is untouched. The client read Jan's cell for the seed and for the record the write claims.\n\nOther shapes on the same fixture, with replies held:\n- `G`, `i` from (0,0) in a 2×6 window: the client declines \"Profit is computed by a formula\" on Cost/Jan. The TUI opens.\n- `g g i` from row 2 with row offset 1: the same wrong decline.\n- `G i 7 Enter`: the TUI stores Jan/Cost = 47, and the client writes nothing.\n\nWhen each reply is delivered before the next key, every one of these agrees.

It argues that reuse is harmless because `document_generation` rejects stale commands. That argument covers the wire only. The ADR's own case for persisting ids (\"Alternatives rejected\") is identity *outside* a session: \"a rename visible as a rename in git diff, and a future reference that survives a restart\". Clause 3 defeats both.\n\n- Reuse after reload. Categories A(3) and B(4). Delete B, save, reload, add C. C gets 4, because the max seen is 3. `git diff` from the first commit to the last shows `B(4)` becoming `C(4)`, which reads as a rename, and an external reference to 4 now silently names C. That is the \"silently names a different thing\" failure clause 3 cites from ADR 002 as the thing ids must never do.\n- Merges. Two branches of one `.improv` each add a category, and both get the next integer. The merged file has a duplicate. Clause 5's repair keeps the first and reassigns the second, so one entity's persisted id changes on merge. Nothing in the file breaks, since nothing refers to an id. But the \"stable across a save and a reload\" promise does not extend to copies or branches, and the ADR does not say so.\n- The generation argument is also per-process: `document_generation` starts again at 0 in a new host process.\n\nMissing open question: whether to persist a high-water mark (for example a `next-id:` line, or per kind), and whether ids should be collision-resistant tokens rather than counters.

Under the ADR's `header_decl` these load as category `Region` with id `code`, and `Size` with id `cm`. Every reference keeps the old spelling (clause 5), so `|Region(code)|: row` and every `## Data` key `|Region(code)|=N, ...` name a category the document no longer declares.\n\nLoading the file the way the new grammar would read it (the headers rewritten to `Region`/`Size`, references untouched) through today's `parse_md` succeeds with no error or warning. The axis lines for the old names are dropped, and every cell stays keyed under a category that does not exist, so none of them is drawn. This is not a rename. It silently orphans all the data and view configuration of a CSV-imported document. `Initial View: Q3(draft)` dangles the same way for a view, and falls back to the default without saying so.\n\nWhat the ADR must do: restate Q3's cost as silent data orphaning, and name the importer as a producer of the shape.

The chain is `eval_formula_folded` -\u003e `eval_expr` -\u003e `Expr::Ref` -\u003e `evaluate_fold` -\u003e `eval_formula_folded` again, and nothing memoises it. Before the PR, the fold summed its members' `evaluate_aggregated`, and those hit `formula_cache`. Now every reference to another formula target is re-evaluated in full at every use, and every leaf is a `fold_stored` scan over each covered member's records. The cost is therefore exponential in how often the formula DAG reuses a node. A diamond like `Margin = Profit / Revenue` + `Profit = Revenue - Cost` already pays for it. `grid_of` re-evaluates the whole grid every frame (gotcha 44), so this lands on the held-key path.\n\nMeasured on an Apple M4 Max (Mac16,6), `--release`. The document has 18,000 cells: Month 12 (four quarters) x Region 25 x Product 20 x 3 measures. Product and Month are on Row, `_Measure` on Column, Region on None. Each figure is `GridLayout::new` plus an evaluation of every cell, best of 5.

A chain of 12 costs 2^13 nodes, 2.1 ms for one cell. That is cheap there, because each leaf is an O(1) `data.get`. The PR routes the common OverHidden + fold case through the same uncached recursion, and makes every leaf a scan.\n\nFix direction: memoise per top-level fold evaluation, with a map keyed by the resolved `CellKey`, owned by the `evaluate_covering` call and threaded through `Reach::Fold`. Circularity detection must survive it, so an in-progress marker should yield \"circular\". `r_circular` in the review's scratch tests is the guard.

That is number-shaped Text (007, 1e3, inf, nan, Infinity, 2024) and a raw CellValue::Error, whose edit_text is 'ERR:msg' and which an untouched commit turns into Text('ERR:msg'). In every such case skipping keeps v, which is what an untouched commit means. The only write it refuses is 'convert this text cell to a number by pressing i Enter', which is not a real intent: type 7. Four design constraints: (1) compare against the seed CAPTURED AT OPEN, not a seed recomputed at commit. The TUI's ctx.display_value and the browser's projected edit_text both move if another client writes the cell mid-edit. Comparing to the current seed makes an untouched editor write its stale text over the other client's value, and the browser's basis claim, taken at compose time, will not reject it. Capturing at open fixes that lost update too. (2) Skip only the WRITE. CommitAndAdvance's advance and re-seed, the mode change, and the records-mode transient-row cleanup (Tab contract) must still run. (3) The browser mouse editor (web/app.js edit/close) calls client.typed_cell unconditionally on commit, so the skip must reach typed_cell_frame too. Put it in one shared protocol function beside typed(), not in JS. (4) It does NOT fix genuinely typed '007' becoming Number(7). That is classification, and it stays out of scope.","created_at":"2026-09-23T05:04:39Z"}],"dependency_count":0,"dependent_count":0,"comment_count":1}

The required check `Browser harness (OPFS contract + shell)` is the `browser` job, which has `needs: build`, and GitHub creates its check run only when `build` completes. On PR #186's own head the check-run IDs show it: the six CI jobs are 107047718800..107047719088 (created 04:41:45), and the harness is 107048169932, created about 04:43:53, after `Build all bundles` completed at 04:43:52. `Test and lint (host)` had already completed at 04:43:45.\n\nSo for a window of about 1-3 s per push, every registered check is COMPLETED and SUCCESS, the required harness check does not exist yet, and GitHub reports MERGEABLE/BLOCKED. A poll that lands in that window (roughly window/interval, so about 5-15% at the default 20 s) gets:\n- on main (before #186): exit 0 on a PR whose required browser check has not run.

A required check that is not registered yet is the ordinary case, not a rare one.\n\nSuggested fix: treat MERGEABLE/BLOCKED with no failed check as a wait, the same way UNKNOWN is treated. A required check that never runs then reaches the timeout and exits 3. That is still not 0, and \"not answered yet\" is the accurate report for it. The `table: MERGEABLE/BLOCKED` expectation changes from 1 to 3, and a gap-sequence case is added.

That is what turns a failed client AddItem, LoadModel and similar into `Rejected(MutationRefused)` with rollback.\n- #185 adds `App::refuse(msg)`, which sets `status_msg` **and** a per-batch `batch_refused`, with **no** abort. The headless exit code reads only `last_batch_refused()`. `context/code/cli.md` §10 states that \"AddItem refuses without stopping anything\".\n\nMerged as they stand, each loses the other's guarantee:\n- With #181's helper at a site, `batch_refused` is never set, so a headless run whose `LoadModel` fails exits 0 (udt2's bug, back).\n- With #185's helper at a site, the frame is not aborted, so the wire reports `Accepted` (bok4's bug, back).\n\nBoth PRs rewrite the same lines, so git will conflict, and a resolver must pick one side.

This is a fourth instance of that PR's own lesson (\"a registry with two construction arms demotes the weaker caller\"). The Codex round closed the first three.\n\n`commit-cell-edit` (CommitAndAdvance, AdvanceDir::Down) is registered with `register`, and its two arms mean different things:\n- the pure arm reads `\u003cmode\u003e \u003cvalue\u003e \u003ccoords...\u003e`: value = args[1], key = parse_cell_key_from_args(\u0026args[2..]);\n- the interactive arm reads only args[0] (the mode). It DISCARDS the value and coords, takes the value from the \"edit\" buffer and the key from ctx.cell_key().\n\nSince #151, `improvise cmd`/`improvise script` and the TUI `:` line build every segment through the interactive arm. The whole-line `parse_line` syntax gate still runs through the pure arm, and it accepts the explicit form. So the gate passes and the other arm runs.\n\nMeasured in the headless CLI on a document with Region = North, South, East, where North=1 and East=3:\n\n  improvise cmd 'commit-cell-edit editing 5 Region/East' -f a.improv\n\n- pre-#151 (f7573bff): East = 5, North = 1. That is the intended result.\n- gh/main (40b8913): **North is DELETED** and East is still 3. Exit code 0 and nothing on stderr. The empty edit buffer was committed to the cursor cell, which is the origin.\n\nSo a script line that names a cell and a value silently destroys a different cell instead. The failure is partial and silent, and it loses data.\n\nRepair shape: the same one #151 used for clear-cell/yank/paste/drill-into-cell. When args carry a value and coords, the interactive arm must honour them. The regression test should write to a cell the cursor is NOT on and assert that the cursor cell survives.\n\nA sibling of the same shape, not yet run (PLAUSIBLE): `toggle-panel-and-focus \u003cpanel\u003e [open] [focused]`. The pure arm honours explicit open/focused. The interactive arm ignores them and toggles based on current state, so `:toggle-panel-and-focus formula false false` now opens the panel when it is closed. It is view-only and not destructive, but it is the same demotion.\n\nA durable guard worth considering: for every `register` entry, whenever the pure arm accepts an argument vector, the interactive arm must build an equal command from it against a context whose cursor is NOT on the named cell.

The loss was only caught because the orchestrator noticed kb-merge print \"529 before\" where it had last printed 805, and compared the count against HEAD.\n\nLIKELY CAUSE: a background `scripts/kb replace` was killed mid-write when the previous Claude Code process exited -- it completed with exit code -1. So a truncated file was left on disk, and every later `kb add` built on it. Nothing committed was lost (HEAD, origin/main and gh/main all held 801); the working tree was restored from HEAD and the six new facts re-added, giving a diff of 6 insertions and 0 deletions.\n\nTWO FIXES, both cheap, both in scripts/kb:\n1. WRITE ATOMICALLY: write to a temp file in the same directory and rename(2) over kb.pl, so a killed write leaves the old file intact rather than a truncated one.\n2. REFUSE A SHRINK on `add`: an `add` must leave count(after) == count(before) + len(delta). kb-merge ALREADY PRINTS both numbers (\"529 before, 4 in delta, 533 after\") -- the check is to compare `before` against the count in git HEAD and refuse if the working tree has fewer facts than HEAD with no `rm` recorded. The tool reported the symptom in its own output and nothing read it.\n\nCheck_the_checker: truncate kb.pl to half, run `kb add`, and assert it REFUSES. Then kill a `kb replace` mid-write (or simulate by truncating between the two phases) and assert the old file survives.\n\nThis is doctrine(a_prose_count_is_checked_by_no_one) in executable form: a number the tool prints every run and no gate compares.","notes":"CAUSE CORRECTED: the user reports having moved git underneath the session at around this time, which is at least as likely as the killed 'kb replace' this ticket first named -- treat the cause as UNKNOWN between the two. That changes the priority of the two fixes: an atomic write only covers the killed-write cause, while REFUSE-A-SHRINK (compare the working-tree fact count against HEAD before any add) catches BOTH, since either leaves a file with fewer facts than HEAD and no rm recorded.

The interactive arm, which builds CursorState::from_ctx(ctx), is never reached from a script. See command/cmd/core.rs:188 for the two-arm register.\n\nConsequence: every Move command (move-selection, scroll-rows, page-scroll, all four jump-*) and enter-advance snapshots a ZEROED cursor at PARSE time, clamps to (0,0), and emits SetSelected(0,0). It is worse than a no-op -- it RESETS the cursor. There is no way to position the cursor from a script, so every cursor-reading command is permanently pinned to the origin: clear-cell, yank, paste, cycle-axis-at-cursor, hide-selected-row-item, edit-or-drill, drill-into-cell, toggle-group-under-cursor, delete-*-at-cursor, commit-and-advance.\n\nDEMONSTRATED AT HEAD (a9cad15), web/demo.improv, Product on row:\n  script A: \"move-selection 2 0\" then \"hide-selected-row-item\"\n  script B: \"hide-selected-row-item\"\nBoth documents came out IDENTICAL, both carrying `hidden: Product/Espresso` -- row 0. diff reports IDENTICAL.\n\nBOTH DIRECTIONS DEMONSTRATED.

The two found by Codex\non the PR are the interesting ones and are bash-5-only:\n  - `local n=\"$1\" name=\"$2\" f=\"...$n...\"` is NOT left-to-right on bash 5: every\n    name is created before the assignments run, so $n is unbound under set -u.\n    macOS ships bash 3.2, where it works.

{"_type":"issue","id":"improvise-e0ex","title":"A ratio renders as an integer: number_format is per view, which is too coarse for one grid","description":"USER 2026-09-22: \"Right now, a Formula like `Margin = Profit / Revenue` displays\nuseless numbers. Probably, in most cases 2 decimal places displayed is sufficient\"\n\nTHE IMMEDIATE CAUSE IS THE FORMAT, NOT THE ARITHMETIC, and that is worth stating\nplainly because the user's own diagnosis pointed at decimal math (filed separately\nas the numeric-tower ticket, which is legitimate on its own merits but is NOT what\nproduces this symptom).\n\nView::default() sets number_format to \",.0\" (improvise-core/src/view/types.rs:56),\nand web/demo.improv sets \",.0\" explicitly on both views. `.0` is ZERO DECIMAL\nPLACES. So Margin = Profit / Revenue, a ratio around 0.66, is rounded\nhalf-away-from-zero (gotcha 8) and drawn as \"1\". Exact decimal arithmetic would\nnot change that by one character: 0.66 formatted with \",.0\" is still \"1\".\n\nTHE REAL DEFECT IS THAT number_format IS PER VIEW, WHICH IS TOO COARSE. One\nformat cannot serve Revenue (18,400 -- wants \",.0\") and Margin (0.66 -- wants\n\".2\" or a percent) in the same grid. Blanket-changing the default to 2 decimals\njust moves the damage: every currency measure becomes \"18,400.00\". So the fix is\nNOT a new default; it is a format that can vary per measure.\n\nWHAT TO DECIDE, in the PR body, rather than assume:\n  - PER WHAT? Per _Measure item is the obvious unit and matches how a user\n    thinks (\"Margin is a percentage\"). Per formula is another candidate and is\n    narrower -- note a formula TARGET is a _Measure item (gotcha 7), so the two\n    are not independent and picking both would be two answers to one question.\n  - WHERE DOES IT LIVE? A per-measure format is document data, so it persists --\n    which means the .improv grammar gains something and persistence/improv.pest\n    is the single source of truth (design-principles section 3). Grammar first,\n    then the tree-walker.\n  - WHAT IS THE FALLBACK? The view's number_format must remain the answer for a\n    measure with no format of its own, or every existing document changes\n    appearance on load.\n  - IS A SENSIBLE DEFAULT INFERRABLE? A formula whose expression is a division\n    is almost always a ratio. Inferring is tempting and is the kind of rule that\n    is wrong 10% of the time and unexplainable when it is -- if you propose it,\n    propose it as a DEFAULT THE USER CAN OVERRIDE and say how they override it.\n\nROUND-TRIP IS THE TEST THAT MATTERS: persistence/roundtrip_tests.rs and the\ngrammar-walking generator. A new format field that does not survive\nformat_md -\u003e parse_md is a silent data loss, and the generator is what will find\nthe spellings you did not think of.\n\nNOTE FOR SCOPE: this is display only. format_f64 is called in rendering and\nnowhere else; formula eval uses full f64 and must keep doing so (gotcha 8 -- never\nfeed a rounded value back into eval). Nothing here touches the evaluator.","notes":"USER RULING 2026-09-22, which NARROWS this ticket from what it was filed as:\n\"We need to default to showing decimals: the expectation is that 2/3 shows\nsomething like .66... rather than 1 for this sort of application, unless the\nformat is explicit in the formula\"\n\nTWO CLAUSES, and the second changes the design:\n\n1. THE DEFAULT SHOWS DECIMALS. View::default()'s \",.0\" becomes decimal-showing.\n   Combined with the user's earlier \"in most cases 2 decimal places displayed is\n   sufficient\", that reads as \",.2\": Revenue draws 18,400.00 and Margin draws\n   0.66. Accounting applications do exactly this, so the noise on whole-number\n   measures is the expected cost rather than a regression.\n\n2. THE OVERRIDE IS SPELLED IN THE FORMULA. This SUPERSEDES the \"per-_Measure\n   item\" framing this ticket was filed with. Per-formula is narrower and is what\n   the user asked for -- and the two nearly coincide, because a formula TARGET is\n   a _Measure item (gotcha 7). So: a formula may carry its own format, which wins\n   for its target; a RAW measure keeps the view's format. Clean split, and the\n   grammar change lands in the `## Formulas` line rather than in a new section.\n\nTHE MIGRATION IS CLEANER THAN EXPECTED -- verified, not assumed. format_md writes\n`format: \u003cfmt\u003e` whenever number_format is non-empty (persistence/format.rs:121),\nand View::default() is non-empty, so EVERY DOCUMENT IMPROVISE HAS EVER WRITTEN\ncarries an explicit format line. format_line is optional in the grammar\n(improv.pest:118/126), so changing the default affects only (a) newly created\nviews and (b) hand-written documents that omit the line. No migration is needed\nfor round-tripped files.\n\nBUT web/demo.improv SETS \",.0\" EXPLICITLY ON BOTH VIEWS (lines 11 and 19), so the\ndefault change alone leaves the front page showing the bug the user reported.\nChange the demo in the same commit, and note tests/web_demo_model.rs asserts\nproperties of that document.\n\nGRAMMAR NOTES for the formula-side format:\n  - The `## Formulas` line already carries a bracket suffix for the target\n    category: `- Tax = Revenue * 0.1 [CustomCat]`. A format needs a spelling that\n    cannot be confused with a category name. Decide it in improv.pest FIRST --\n    the grammar is the single source of truth and the tree-walker follows\n    (design-principles section 3).\n  - The grammar-walking generator reads improv.pest via pest_meta and will\n    exercise whatever you write, including spellings you did not intend. Note it\n    SKIPS PREDICATES (gotcha 34), so a rule guarded only by a lookahead is a rule\n    the generator can violate -- use a real token, as WHERE's `sp+` does.\n  - Formula::raw is what the writer emits, not the reconstructed text, so a\n    format that round-trips through `raw` may appear to work while being dropped\n    from the parsed structure. gotcha 34 records exactly that failure for the\n    formula TARGET: the round-trip tests never saw it because raw was unaffected.\n    Assert the PARSED format, not the re-emitted line.\n\nSTILL DISPLAY ONLY. format_f64 is called in rendering and nowhere else; eval uses\nfull f64 and must keep doing so (gotcha 8). ADR 005 (improvise-l2b8) is the\nseparate question of what the arithmetic itself is, and nothing here waits on it.\nUSER CONSTRAINT 2026-09-22: \"improvise-e0ex should not affect persistence at all,\nexcept to store format metadata.\"\n\nALREADY TRUE BY CONSTRUCTION -- verified before recording, so the job is to NOT\nBREAK IT rather than to build it:\n\n  - DISPLAY formatting is format_f64 in improvise-core/src/format.rs. Its only\n    callers are rendering paths.\n  - PERSISTENCE formatting is a DIFFERENT function in a DIFFERENT crate:\n    persistence/format.rs:38 `fn format_number(n: f64)`. It writes `{n}` --\n    Rust's shortest round-trip representation -- for non-integers, `{n as i64}`\n    for integers below 1e15, and named forms for inf/-inf/nan.\n  - `grep format_f64` over crates/improvise-io, crates/improvise-core/src/*.rs\n    and src/*.rs returns ONLY format.rs's own definition and its tests.\n    PERSISTENCE NEVER CALLS THE DISPLAY FORMATTER.\n\nSo stored values keep full round-trip precision regardless of what any view's\nnumber_format says, and a ,.2 default cannot round anything on disk.\n\nTHE REGRESSION TO WATCH FOR, stated because it is the one way this constraint\ngets violated by someone trying to be helpful: routing a save through the display\nformatter \"so the file matches what the user sees\". That would make the on-disk\nvalue depend on a VIEW's setting -- and a model has many views (gotcha 29), so\nthere is no single right answer and the last save would win. gotcha 8 already\nforbids feeding a rounded value back into eval; this is the persistence twin of\nit and is now written down.\n\nWHAT IS IN SCOPE ON THE PERSISTENCE SIDE, and it is only metadata:\n  1. The per-formula format spelling in the `## Formulas` line -- grammar first\n     in improv.pest, then the tree-walker.\n  2. The `format:` line's VALUE for newly created views changes with the default\n     (\",.0\" -\u003e the decimal default). That is metadata, not data, and existing\n     documents are unaffected because format_md has always written the line\n     explicitly (format.rs:121) whenever number_format is non-empty.\n\nNOTHING ELSE IN .improv CHANGES. No data line is rewritten, no number is\nre-rendered, no migration is needed.\nFIXED in PR #125 (merge 5fdce21). 1654 tests, all gates green.\n\nMEASURED, not asserted -- web/demo.improv through project::grid_of, the path both\nfront ends use:\n              Revenue     Cost      Profit     Margin\n  before      18,400      6,200     12,200     1\n  after       18,400.00   6,200.00  12,200.00  0.66\n  with FORMAT .4 on a ,.0 view                 0.6630\n\nONE CORRECTION TO THIS TICKET AND TO THE BRIEF I WROTE FROM IT: the demo has NO\nMargin formula -- only `Profit = Revenue - Cost`. Verified on main. So the front\npage was never literally showing the reported symptom; it was showing ,.0 on\nevery measure. My brief asserted the demo would \"still show the bug\" after a\ndefault change, which was wrong because I assumed a ratio that is not there.\nThe agent declined to ADD a Margin formula: that is demo content nobody asked for\nand it moves tests/web_demo_model.rs's asserted column list plus harness\nassertions. It is a two-line change if the user wants the ratio on the front page.\n\nTHE GRAMMAR DESIGN IS BETTER THAN THE BRIEF ASKED FOR. improv.pest is UNCHANGED\n-- verified. formula_raw already takes the `## Formulas` line verbatim up to the\noptional [Category] suffix, so the format rides in the FORMULA TEXT:\n  format_clause = ${ ^\"FORMAT\" ~ sp+ ~ format_spec }\nin formula.pest, after the optional WHERE, with sp+ rather than a lookahead for\nWHERE's reason (the grammar-walking generator skips predicates). Consequences:\nthe generator has no new spelling to exercise, and the text a user types into the\nTUI minibuffer is the text the file carries -- one namespace, one spelling rule.\nRejected: a `{.2}` line suffix, which puts the format somewhere a user cannot\ntype it.\n\nTHE raw-VS-PARSED TRAP WAS ANSWERED WITH A MEASUREMENT. Injecting a walker that\nDISCARDS the format clause fails exactly ONE test and passes 242 others in\nimprovise-io, including the whole format_md/parse_md characterization suite and\nthe grammar-walking properties. No text-comparing test can see the field go\nmissing -- which is the gotcha-34 shape this ticket warned about, now quantified.\n\nBOTH CODEX FINDINGS WERE REAL, and both are the kind that only review catches:\n  1. FormatPlan used a HashMap keyed by target. A target category need not be\n     _Measure, so a key can be claimed twice and HASH ORDER DECIDED THE SPELLING\n     while model order decided the value -- gotcha 18's shape in a new place.\n     Now: every formula's (cat, target, Option\u003cformat\u003e) in MODEL order, FIRST\n     match wins, and a match naming no format falls through to the view.\n  2. A column total took its format from ROW 0. The agent's own context/ prose\n     had argued this was safe \"for the case it cannot arise in\" -- and it arises,\n     because a formula's target category is any category and can own a ROW-AXIS\n     item. New GridLayout::column_key(col) gives the coordinates surviving the\n     row aggregation.\n\nTWO FIXTURES PINNED TO ,.0 RATHER THAN RE-BASELINED, and the first is the\nimportant one: improvise_gp::dataset::a_cell_reaches_the_table_unrounded asserted\nits fixture's format WAS ,.0 as a precondition, then checked a stored 5.25\nreaches a fit unrounded. UNDER A ,.2 DEFAULT THAT TEST WOULD HAVE GONE VACUOUS\nWHILE PASSING. The fixture now sets ,.0 explicitly.\n\nNO .improv DATA LINE CHANGED.

True, and\nMISLEADING. Two paths do this:\n\n  - effect::apply_coordinate_rename (ui/effect.rs:655), inside ApplyAndClearDrill,\n    which is deliberately off the wire (gotcha 38).\n  - commit.rs::rename_record_coordinate (cmd/commit.rs:366), the plain records path,\n    which ALREADY decomposes into [AddItem, ClearCell(old), SetCell(new)] -- three\n    commands that all have ModelCommand forms.\n\nSo it reads as though the plain path were already wire-expressible. IT IS NOT, for a\nreason the ticket does not state: ModelCommand::SetCell takes a RecordCell, whose\nRecordHash is an OPAQUE SURROGATE the server resolves against cells that ALREADY\nEXIST (App::resolve_record, ui/app.rs:516). The renamed record does not exist yet, so\na client cannot name it.\n\nTwo things that look like they solve this and do not. `will_be_created_by_the_frame`\n(ui/reduce.rs:284) exempts such a record from the BASIS CHECK -- it says nothing about\nhow to NAME one, and the two are easy to confuse. And RecordHash::of being pub is not\na licence: a client computing surrogates is precisely the invention ADR 002 exists to\nprevent.\n\nWHAT TO ADD: one position-free variant naming the existing record by surrogate and the\nnew coordinate by value --\n\n  ModelCommand::RenameRecordCoordinate { record: RecordHash, category: String, item: String }\n\n-- mapped to a SINGLE effect factored out of the two copies above. Position-free, so\nimprovise-hkbc's rule still holds. Add it to records_named's match: it names one\nrecord, and creating the ITEM is internal to the effect, as both existing copies\nalready do.\n\nCONSOLIDATING THE TWO COPIES IS WORTH DOING REGARDLESS. They differ today only in how\nthey report the empty-value refusal, and gotcha 19 already warns that the synthetic-\nrecords branch and the plain branch drift.\n\nREMEMBER gotcha 1: renaming a category coordinate in wide records mode moves EVERY\nmeasure cell in the row, not just the one under the cursor. That is also why the basis\nunit is the record (gotcha 40) -- a cell-level unit is violated by this one legal edit.\n\nRELATED: improvise-o9uq is about the same code.

RenameRecordCoordinate would be a ModelCommand that nothing composes, which is the promise-not-kept shape vocabulary_is_composed.rs refuses for Command. Composing it needs the browser half of commit_plain_records_edit, and that needs RecordCol, which is session-local by gotcha 1. bd9o records that as a design question.

The user should be editing the row it just added. Instead: the new row 2 is created and left empty, THE CURSOR LANDS ON ROW 0, the editor is pre-filled with row 0's Region coordinate \"East\", the typed text APPENDS, and Enter goes through commit_plain_records_edit -\u003e RecordCol::Category -\u003e rename_record_coordinate, WHICH RENAMES THE PRE-EXISTING EAST RECORD TO EastNorth and moves all its measure cells.\n\nA user adding a row silently corrupts an unrelated one.\n\n## Two independent causes, both needed for the full damage\n1a (longstanding). AddRecordRow::execute (cmd/grid.rs:518) returns only SetCell + set_status — it NEVER POSITIONS THE CURSOR. EnterEditAtCursorCmd then opens an editor on whatever the cursor is on. Contrast CommitAndAdvance's Tab-at-bottom-right path (commit.rs:547), which calls the same AddRecordRow and DOES follow it with viewport_effects(cursor.row + 1, 0, ..). One of the two AddRecordRow call sites places the cursor; the `o` binding is the one that does not.\n\n1b (regression of improvise-ni6k / gotcha 24). AddRecordRow's SetCell is Model(CellData), so the frames_basis arm diffs every view's frame; appending a row changes the hash, moved.contains(view) is true, and reset_cursor() fires MID-BATCH, before EnterEditAtCursor. Isolated and demonstrated:\n    apply_effects([SetCell(CellKey::new(vec![]), Number(0.0))]) from sel=(1,0)\n    -\u003e sel (1,0) -\u003e (0,0), cursor_epoch 2 -\u003e 3\n\n1b IS A DEFECT ON ITS OWN TERMS: appending a row does not renumber any existing row, yet view_frame hashes entries.len() and every entry, so ANY APPEND REFRAMES and throws the cursor to the origin. In records mode that is every record insert. The Tab path only escapes it by re-placing the cursor afterwards.\n\n## Also observed, same root, lower severity\nPressing `o` twice with no page-axis category adds ONE row, because both emit SetCell(CellKey::new(vec![])) — the same empty-coordinate record — while the status says \"Added new record row\" both times.\n\n## Acceptance Criteria\n- AddRecordRow::execute appends viewport_effects(new_last_row, 0, ..) after its SetCell, so the cursor lands on the row it created. Harmless at the CommitAndAdvance call site, whose own later viewport_effects wins and survives because the observation is inside the loop. Fixes 1a and masks 1b at this site.\n- A test driving the exact key sequence above and asserting the East record is UNTOUCHED.\n- 1b proper wants the frame observation to distinguish \"rows appended\" from \"rows renumbered\" — a separate, larger question. File it rather than fold it in.\n- Two `o` presses should add two rows or say why not.\n\nScope: TUI only. resolve.rs:237 puts add-record-row in declined(), so no browser client reaches it.\n","notes":"FIXED in PR #126 (merge 4625593). TUI-only.\n\nTHE MECHANISM, which is more interesting than the symptom: o is\n[add-record-row, enter-edit-at-cursor records-editing], and AddRecordRow::execute\nreturned SetCell plus a status and NEVER PLACED THE CURSOR. Appending a record\nchanges view_frame's hash, so the frame observation INSIDE apply_effects\ninvalidated the cursor to the origin MID-BATCH (gotcha 24). EnterEditAtCursor then\npre-filled the editor with ROW 0's category coordinate, and Enter went through\nrename_record_coordinate -- which by gotcha 1 moves EVERY measure cell of that row.\n\nREPRO through App::handle_key, not a hand-placed state: Region{East,West},\nRevenue 10/20, R, sel=(1,0), then `o N o r t h Enter` -- East's Revenue cell GONE,\nrows [\"0\",\"1\",\"2\"], East renamed EastNorth.\n\nTHE ORDER IS THE ENTIRE FIX, and the rival proves it: moving viewport_effects\nAHEAD of the SetCell fails both tests and IS THE BUG VERBATIM. That rival is the\none worth keeping, because the acceptance criteria say \"append viewport_effects\"\nand do not say WHERE, and the two orders are indistinguishable by reading.\n\ntarget_row is row_count() (an append is last) UNLESS the record already exists, in\nwhich case it is that record's index found by scanning record_row(r).coords --\npredicting row_count() unconditionally puts the cursor one past the end in that\narm. That arm also stops claiming \"Added new record row\" for a row it did not add.\nIt is deliberately NOT made a refusal: CommitAndAdvance's Tab-at-bottom-right path\ncalls the same command and depends on seeding an empty-coordinate row.\n\nDOES NOT NEED improvise-fdk1, and fdk1 does not subsume it. o9uq is TUI-side\ncursor placement; add-record-row is in declined(), so no browser client reaches\nthe path. fdk1 is a COMMIT-side protocol gap. They meet only at\ncommit.rs::rename_record_coordinate -- the function o9uq stops being reached\nwrongly, and the one fdk1 wants factored into a single effect. Closing fdk1 would\nstill leave o editing row 0.\n\nTHE TELL WORTH GENERALISING: CommitAndAdvance's Tab path ALREADY did this fix, at\nthe CALL SITE. One of two callers of AddRecordRow placed the cursor and the other\ndid not -- so the placement was a property of the caller where it is a property of\nthe command. Look for that wherever two call sites of one command differ in what\nthey do afterwards.\n\nFOLLOW-UPS NOT FILED (no bd writes from the agent):\n  1. o twice with no page-axis category still adds one row (both build\n     CellKey::new(vec![])); it now says so rather than claiming otherwise.\n  2. view_frame hashes entries.len() and every entry, so it cannot distinguish\n     \"rows appended\" from \"rows renumbered\" -- every append throws the cursor to\n     the origin.

That would also have caught this when GridCache::totals and page_coords were added (improvise-n10).\n\n## Acceptance Criteria\n- RenderModel gains page_coords and totals, fed straight off state.grid, and app.js/shell.js::gridPlan paint them.\n- SEPARATELY AND FIRST IF NEED BE: extend render_surface.test.js to the widget caches. File the guard even if the painting is deferred — an unpainted field with an argument in UNPAINTED is debt; an unpainted field nothing can see is the next one.\n- A harness assertion that the page bar names the selected item, since the demo ships with a page axis.\n","notes":"USER RULING 2026-09-21, PROMOTED P2 -\u003e P1: 'there is no UI at all for page-level dimensions'.\n\nVERIFIED at 523d571, and the shape matters -- this is not 'unbuilt', it is built to one step short of the screen:\n\n  improvise-protocol/src/render.rs:433   pub page_coords: Vec\u003cPageAxis\u003e   on GridCache\n  improvise-protocol/src/render.rs:475   GridUpdate::PageCoords(..)       seeded in the bootstrap\n  improvise-protocol/src/render.rs:620   GridUpdate::PageCoords(coords) =\u003e self.page_coords = coords\n  improvise-wasm-client/src/render.rs    *** page_coords / PageAxis ABSENT ***\n  web/app.js                             *** paints nothing page-related ***\n\nSo the server projects it, the browser's GridCache folds it and maintains it\ncorrectly, and RenderModel never exposes it. The page bar's data is sitting in\nthe client, one field away from being drawable.\n\nThis also explains why the parity sweep did not catch it. That audit checked\n'every field RenderModel EXPOSES is painted' and found that set empty -- a true\nand useful result. It could not see a field that never reaches RenderModel at\nall. A missing field is invisible to an exposed-but-unpainted check, which is\nworth remembering before trusting that audit's clean bill again.\n\nWHY THIS IS NOW P1 RATHER THAN A COSMETIC GAP: three user reports converge on\nit.\n - improvise-z336: clicking a category item PUTS the category on the Page axis.\n   With no page bar, the user has moved a dimension onto a surface that is\n   invisible, which is most of why the filter felt impossible to clear.\n - The TUI's [ and ] page cycling has no browser affordance, so the one\n   navigable axis (gotcha 27: Page is navigable, Filter is not) cannot be\n   navigated.\n - A pivot table whose page dimension is invisible is missing a third of its\n   layout vocabulary -- Row, Column and Page are the three visible axes.\n\nSCOPE NOTE: this bead also covers column totals, which are the same shape --\nGridCache::totals is projected and held, and the browser paints nothing. Those\nmust be PROJECTED rather than client-derived, because the sum runs over every\nrow including ones a viewport scrolled past (gotcha 44). If whoever takes this\nwants to split totals out, that is fine; do not 'fix' them by summing in the\nclient.\n\nRelated and not the same: improvise-pcje is the residue of the parity sweep\n(col_widths, column ancestry, AxisColor, tile overflow) after this bead's two\nitems are removed.\nCLOSED: both halves are done, verified by re-running THIS TICKET'S OWN REPRO\nCOMMAND against d46ec59.\n\nThe ticket's evidence was:\n  $ grep -rn \"page_coords|totals\" crates/improvise-wasm-client/src/ web/\n  (no matches)\n\nRe-run now:\n  render.rs:37   pub totals: Vec\u003cRenderCell\u003e\n  render.rs:40   pub page_coords: Vec\u003cRenderPageAxis\u003e\n  render.rs:282  totals: totals_strip(state)\n  render.rs:283  page_coords: page_axes(state)\n  app.js:518-526 paints the totals strip\n\nHALF 1, the page bar: painted, and since improvise-rw6l (PR #123) each navigable\naxis is a button carrying a down-arrow that opens a menu of its items, with\nClick::PageItem composing SetPageSelection.

Suggested wording: the values are too large for 32-bit arithmetic because their spread overflows; scale the measure (thousands, millions) and fit that.\n- The check is on the DERIVED quantities (mean, std) after standardize, not only on the inputs.\n- A test at a spread that overflows and one just below it, so the guard is not satisfied by refusing everything.\n- Note the same overflow silently corrupts cv_regress's quality numbers today with NO panic to announce it — so a fix that only catches the panic leaves wrong R2 values being reported.

Eight rows at a 1.5e20 spread give 1.8e40, past f32::MAX, so std = inf; every normalized target becomes +/-0 and denormalize computes 0.0*inf + mean = NaN, surfacing two crates away. EVERY INPUT WAS FINITE, which is why fit_measure's input guard saw nothing -- the overflow is in the DERIVED quantity.\n\nTHE SHAPE OF THE FIX: Scaling is a type with private fields and one constructor that refuses a non-finite part, so standardize returns Option\u003c(rows, Scaling)\u003e and denormalize cannot be handed a poisoned map at all. Rejected: a finiteness check at the call site, and the is_finite guard at lib.rs:288 -- both leave the arithmetic intact. cv_regress also pools nothing for a fold it cannot standardize, which closes the SILENT half: before, the same overflow corrupted R-squared with no panic to announce it.\n\nONE CORRECTION TO THIS TICKET'S OWN TRACE: the proposed sibling path (mean = inf while NaN.max(1e-6) launders std to 1e-6) does not occur from finite inputs -- (t-inf)^2 is +inf, so the variance is +inf, never NaN. The mean half of the constructor's check is a contract of the type, not a reachable path. Documented in context/code/gp.md section 7.\n\nSCORING BIT PATTERNS UNCHANGED. scoring_known_answers.rs shows 3 insertions / 3 deletions, which looks alarming and is call-site adaptation only; every literal is identical.

DEMONSTRATED end to end through the real import path. Orchestrator re-verified each link independently.\n\nCategoryKind::Label is not persisted. format.rs writes every category as a bare `## Category: Name`; improv.pest has no syntax for a kind; parse.rs:325 reads every section back through `wb.add_category(\u0026pc.name)?` and NEVER add_label_category. So the kind is dropped on the way out AND on the way in, which is why no round-trip equality test can see it (doctrine a_roundtrip_equality_is_blind_to_a_loss_both_sides_share, exactly).\n\n## Why this is a lost document, not a lost flag\nLabel is deliberately OUTSIDE the 12-category pivot limit:\n  - Model::add_label_category (core/model/types.rs:295) has NO limit check. Verified.\n  - The wizard's precondition ImportPipeline::proposed_category_count (io/import/wizard.rs:97) scores `FieldKind::Measure | FieldKind::Label =\u003e 0`. Verified.\n\nSo the wizard correctly accepts 12 categories + N labels. On load each label is re-created as Regular, and Model::add_category checks the limit BEFORE the idempotent-duplicate check, so the 13th is refused and parse_md fails.\n\n    ANY DOCUMENT WHERE regular + label \u003e 12 IS PERMANENTLY UNLOADABLE.\n\n11 regular + 2 labels fails too.\n\n## Steps to Reproduce\nA JSON/CSV with 12 low-cardinality text columns, one measure, and one high-cardinality text column (\u003e20 distinct values — analyzer.rs:161 auto-classifies it FieldKind::Label, accepted: true). An id, description or free-text note column does this in any real CSV.\n\n    proposals include (\"Note\", Label, true)\n    proposed_category_count() == 12          \u003c- precondition asserted, within the limit\n    wb.model.category(\"Note\").kind == Label  \u003c- precondition asserted\n    parse_md(format_md(wb))  -\u003e  Err(\"Maximum of 12 categories reached\")\n\nAlso reproduced at the Workbook level: 12 add_category + 1 add_label_category.\n\n## The quieter half, below the limit\n    Region + label Note  -\u003e  round trip  -\u003e  kind: Regular, expected Label\nA label silently becomes a pivot category: it enters regular_category_names() pickers, counts against the limit, and gains axis auto-assignment.\n\n## Acceptance Criteria\n- The format carries the kind. Suggested: a kind suffix on category_section (`## Category: Note [label]`), written by format_md when cat.kind == Label, read by build_category into add_label_category. GRAMMAR FIRST — improv.pest is the source of truth (design-principles §3).\n- A round-trip test asserting the KIND, not just the name and items. Note the existing suite cannot see this class; a test that only compares formatted output will pass either way.\n- Decide what an older file without the marker means on load. Regular is the compatible reading and is what happens today.\n\n## Two independent mitigations, each correct on its own merits\n- Swap the two guards in Model::add_category so the duplicate check precedes the limit check. Filed separately as improvise-f86q.\n- Give add_label_category a limit of its own, so the unloadable document cannot be CREATED.\nNeither alone recovers documents already written; only the format fix does.\n","notes":"FIXED in PR #129 (merge bf83294).

It suggested `## Category: Note [label]`. THE GRAMMAR FORBIDS IT:\nheader_name takes the name as the WHOLE line, totally (improvise-pczv, gotcha 34),\nso the suffix is indistinguishable from a category literally named \"Note [label]\".\nAdopting it would have made a legal name unspellable and re-opened the ambiguity\nheader_name exists to close.

Grammar first --\nkind_line = { \"kind: \" ~ kind_kw ~ NEWLINE ~ blank_lines }, kind_kw = @{ \"label\" }\nas a category_entry alternative, verified by the orchestrator. A REAL TOKEN and\nnot a lookahead, because the generator reads the grammar through pest_meta and\nSKIPS predicates.\n\nABSENCE MEANS REGULAR, so every pre-dy3j file parses unchanged and a pivot\ncategory's section is byte-identical. parse_kind_kw is an exhaustive\nResult-returning match rather than a bool read off the rule's PRESENCE, so a\nfuture second keyword fails at the walker instead of being silently read as\n\"label\" because it arrived on a kind_line.\n\nTHE RIVAL THAT MATTERS: a reader that parses the kind and DISCARDS it. The file\ntext is then correct, so every output-comparing test passes -- which is why the\nnew assertions are on the parsed Category::kind and never on the emitted line.\nThis is a second worked instance of\ndoctrine(a_roundtrip_equality_is_blind_to_a_loss_both_sides_share): the kind was\ndropped symmetrically, out and in, so the whole characterization suite was silent.\n\nAND THE SEVERITY WAS REAL: Label is outside MAX_CATEGORIES = 12 while the wizard\nwill happily build 12 + a label, so any such document was PERMANENTLY UNLOADABLE.\na_document_at_the_category_limit_plus_a_label_reloads also asserts\nregular_category_names().len() == 12, because a \"fix\" that merely raised the limit\nwould load the document while putting a high-cardinality label into the pivot\ncount.\n\nNOTE THIS TICKET'S MITIGATION LIST IS STALE: it names improvise-f86q as\noutstanding, and f86q is already fixed -- Model::add_category has idempotence\nbefore the limit check, with the ticket cited in a comment.","status":"closed","priority":1,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-21T20:23:30Z","created_by":"Edward Langley","updated_at":"2026-09-22T08:32:22Z","closed_at":"2026-09-22T08:32:22Z","close_reason":"Closed","dependency_count":0,"dependent_count":0,"comment_count":0}

The view-configuration half of `ModelCommand` — SetAxis, CycleAxis,\nTransposeAxes, SetPageSelection, HideItem, ShowItem, ToggleGroup, TogglePruneEmpty,\nSetNumberFormat — acts on \"the active view\", which is now an ambiguous phrase.\n\n`Sessions::apply_model` routes with no SessionId (gotcha 38, correctly: the change\nis addressed to no one session, because a `View` is document state shared by every\nclient sitting on it). But it must still name WHICH view, and today it names it\nimplicitly: `apply_command` runs the effect against the `App`, and the effect reads\n`App::view()`, which is the HOST's slice. So a connected client on another view\nmoves the host's view rather than its own.\n\nBefore jytm every client was on the same view, so the implicit answer was right.\nIt is now wrong exactly when two clients are on different views, which is the\ncapability jytm exists to add.\n\nThe honest fix is for those variants to name their view — a protocol change — so\nthe command carries the operand rather than borrowing an ambient one. Rejected\nduring jytm: retargeting `app.view_state.active_view` around `apply_command` at the\ndoor. It makes the host's own UI slice a parameter channel, and `reset_cursor`/\n`cursor_epoch` would then write the asker's key into the host's cursor map.\n\nNote the `_Drill`/`_Records` virtual views make this sharper than it looks: a host\nin records mode is on a view no client can name.\n\n## Steps to Reproduce\n\n1.

The axis moves on \"Default\" — the view B is not on — and B's next projection\n   shows nothing changed while A's shows a change A did not ask for.\n\nNot reachable from the TUI, which is the only client that drives the App's own\nslice, and not reachable from `web/app.js` today because it sends no SwitchView.\n","acceptance_criteria":"The view-configuration ModelCommand variants name the view they act on, so a connected client's SetAxis moves the view that client is on and not the host's.

This is deferrable, but it is deferred on a CONDITION rather than on a judgement, and the condition is one line of somebody else's future work away. It is unreachable today ONLY because no shipped client emits Command::SwitchView. That is the whole of the argument. The browser already emits view-configuration model commands -- keys.rs resolves a keypress to ModelCommand::TransposeAxes locally and sends it -- so the machinery on the other side of the ambiguity is live. THE DAY ANY WAVE WIRES A VIEW SWITCH INTO THE BROWSER, THIS GOES LIVE ON THE NEXT TRANSPOSE KEYSTROKE, AND SILENTLY: a client on Second presses transpose, the axes of Default move instead, that client's grid does not change and every other client's does. Two consequences. (1) Do not close this by arguing it is unreachable -- reachability is the thing that is about to change, and gotcha 47 already records that 'unreachable today' was the argument under which the lost update CheckedBatch later fixed had shipped. (2) There is a cheap interim guard worth landing before the real fix: assert that no shipped browser client emits Command::SwitchView, a test over improvise-wasm-client's key resolver. It turns the silent failure into a loud one at exactly the moment the premise stops holding, which is the only moment anybody would otherwise not be looking.\nTHE PREMISE IS ALREADY FALSE (verified 2026-09-20 at 585f25b by wave3 protocol agent, by enumerating the resolver rather than reasoning about it).\n\nThis ticket's own note says it is deferred on a CONDITION -- 'it is unreachable today ONLY because no shipped client emits Command::SwitchView' -- and asks for an interim guard that asserts exactly that. I wrote the guard. IT FAILED IMMEDIATELY. Two live paths, both in the browser's own resolver at crates/improvise-protocol/src/resolve.rs:359-368:\n\n  VIEWS: switch-view-at-cursor  -\u003e switch_view_at() -\u003e Command::SwitchView\n  VIEWS: create-and-switch-view -\u003e CreateView + Command::SwitchView\n\nand the other half is live too: resolve.rs:331 composes ModelCommand::TransposeAxes locally. So the exact scenario the note describes -- 'a client on Second presses transpose, the axes of Default move instead, that client's grid does not change and every other client's does' -- is reachable TODAY from the shipped browser view panel. It is not a future risk; it is a live P2-turned-P1 bug.\n\nEscalated to P1 on that evidence.\n\nThe guard landed anyway, as the_keys_that_compose_a_switch_view_are_these in resolve.rs, but as an ASSERT_EQ against those two names rather than an assert-empty -- it pins reality and fails on a third live path, and its message says the list is not an exemption list. When lltt is fixed the list goes empty and the test goes with it.\n\nNOT FIXED HERE, deliberately: the honest fix is the protocol change this ticket describes (the nine view-configuration ModelCommand variants naming their view), which means every view-writing effect taking a view name instead of calling App::view_mut(). That is a whole work unit and it should not be smuggled into one alongside nine other tickets.\nNOT CARRIED BY PR #78. Releasing the claim so the tracker stops implying someone is on it.\n\nWHAT #78 CONTAINS: only the DETECTOR. the_keys_that_compose_a_switch_view_are_these (improvise-protocol/src/resolve.rs) enumerates every binding every mode can reach and asserts the set composing Command::SwitchView is exactly {switch-view-at-cursor, create-and-switch-view}. That is what overturned this ticket's deferral premise and got it escalated to P1. It fails if a THIRD live path appears; it does not fix any of the two that exist.\n\nWHAT #78 DOES NOT CONTAIN: the fix. No ModelCommand variant names a view; no effect takes a view name; App::view_mut() is still what every view-configuration effect writes through. The bug is exactly as described in the original report.\n\nWHY NOT: the honest fix is the protocol change this ticket describes -- the nine view-configuration variants (SetAxis, CycleAxis, TransposeAxes, SetPageSelection, HideItem, ShowItem, ToggleGroup, TogglePruneEmpty, SetNumberFormat) naming their view, which means every view-writing effect taking a view name instead of reading the ambient App::view_mut(). That touches ui/effect.rs broadly and ui/reduce.rs's mapping, and it is a work unit. Landing it inside a PR already carrying nine other tickets would have got it the least review of anything in the PR, which is the wrong trade for a P1 in the concurrency layer.\n\nONE THING FOR WHOEVER TAKES IT, which the ticket does not say: the bug is already written into a PASSING TEST'S COMMENT. a_reshape_of_one_view_leaves_a_client_on_another_view_alone carries 'Aimed at the host's own view... HideItem writes view_mut()' -- a correct description of the defect, read for as long as it has been there as a fixture note. Worth grepping for siblings of that shape before starting.\n\nUnclaimed, still P1, still open.","status":"closed","priority":1,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-20T18:05:49Z","created_by":"wave2-e-active-view","updated_at":"2026-09-21T20:15:00Z","started_at":"2026-09-21T03:28:15Z","closed_at":"2026-09-21T20:15:00Z","labels":["area:active-view"],"dependency_count":0,"dependent_count":0,"comment_count":0}

If code comments are needed, at most two consecutive lines of comments and possibly a context/ doc reference for more details (but don't overdo this).\"\n\nSCOPE RULED BY THE USER, both maximal:\n * The two-line cap applies to `///` and `//!` DOC COMMENTS as well as `//` implementation comments.\n * It applies to TEST doc-comments too. The bug narratives this repo's doctrine puts on a regression test move to prose keyed by test name.\n\n## The measurement\n\n103 Rust files, 12,533 comment lines, 2,961 comment runs of which 1,306 are longer than two lines, and 12 doctest fences inside doc comments. Worst single runs: worker.rs 121 consecutive lines, ui/reduce.rs 119, improvise-gp/lib.rs 84, gp-tree/examples/fit_csv.rs 79, wasm-client/keys.rs 78, cmd/fit.rs 59, dataset.rs 57, registry.rs 56, basis.rs 56, vfs.rs 55.\n\n## What makes this hard, and why it is not a formatting change\n\nTHE REASONING IN THOSE COMMENTS IS THE MOST EXPENSIVE ARTEFACT IN THE REPOSITORY. The post-wave documentation review concluded that the code's doc comments are now BETTER than context/repo-map.md, naming src/ui/grid.rs, worker-server/src/lib.rs, ui/reduce.rs and protocol/render.rs as carrying the full argument correctly. Several of them were written in response to a bug that cost a review round to find, and they exist because someone could not re-derive the rule from the code.\n\nSO THIS IS A MOVE, NOT A DELETION. Every argument either lands in context/ prose or is dropped DELIBERATELY as a restatement of what the code plainly says. The failure mode to avoid is a tidy diff that quietly loses the one sentence explaining why a check exists — which is the shape that reintroduces the bug the check guards.\n\n## The convention\n\n * A comment run is AT MOST TWO CONSECUTIVE LINES.\n * It may carry a `context/` reference for the rest -- but SPARINGLY, per the user (\"don't overdo this\"). A pointer on every function is noise; a pointer where a reader would otherwise re-derive a rule wrongly is the point.\n * Prose lands in context/ files owned by ONE area each, so parallel work does not collide.\n * Test evidence -- what broke, what was injected, why the test can fail -- lands in a test-evidence file keyed by TEST NAME.\n\n## Known hazards\n\n * TWELVE DOCTEST FENCES live inside doc comments. Capping a `///` block that contains a ``` example DELETES A RUNNING TEST. Find them first and decide each: promote to a real test, or keep the fence and cap around it.\n * A `//!` module doc is often the only orientation a file has. Losing it entirely costs more than it saves; the cap applies, so what survives must be the two lines that matter.\n * `#[allow(...)]`, `#[cfg(...)]` and clippy directives are ATTRIBUTES, not comments -- do not touch them.\n * A test name is the key into the evidence file, so RENAMING A TEST ORPHANS ITS ENTRY. Whatever convention is chosen must make that detectable.\n","acceptance_criteria":"No comment run in any .rs file exceeds two consecutive lines, verified by a script that is kept in the repo so the rule is checkable rather than remembered. Every argument that was in a capped comment is findable in context/ -- spot-checked by sampling the worst ten files and confirming their reasoning survived. cargo test --workspace --no-fail-fast stays at 1309 passing (or higher, if a doctest fence was promoted to a real test), and git diff filtered for non-comment lines is EMPTY -- no behaviour changed.

RenderModel gained a RenderRow ENUM so a group header cannot carry cells.\n\nEVIDENCE: the_whole_frame_is_unchanged passes byte for byte, which is the proof the TUI did not move -- and its doc comment now states honestly what it does NOT cover (both its axes are single-level, so it exercises no multi-level suppression), with the multi-level half pinned by the new tests/grid_frame_agreement.rs. That test drives the ratatui widget into a buffer and the browser client through a Snapshot OF THE SAME CACHE and compares WHAT EACH DRAWS -- comparing caches would be vacuous, since it is one cache.

The sharp case is an AXIS SWAP rather than a rename: two categories may legally share an item name, so the preserved CellId::Record stays VALID and addresses the OTHER record, a genuine misdirected write. And it was wrong end to end, not only in apply: grid_updates diffs cells against the FRAMED mirror, so an apply that kept them made the producer agree they matched and SEND NOTHING AT ALL, leaving the client re-identified with nothing in the stream that could ever correct it -- wrong forever, the direction Dirty::of is deliberately sloppy to avoid. Fixed with frame-only regression tests (no Cells or Totals behind them) and a load-bearing negative arm.\n\nWHAT THE ACCESSOR MIGRATION COST, which no test could see: replacing GridLayout access with AxisFrame accessors put an O(n) scan behind every item(idx), so a draw loop calling it per position per level became quadratic AND proportional to the absolute scroll offset. The old widget's one materializing line was load-bearing.

Now: attach indexes nothing, write indexes and un-queues a pending delete of the name, refresh skips zero-byte entries.\n 2. A second tab could break the first's picker -- found by reading the fix for (1). refresh now measures sizes, and a file under another context's exclusive sync handle is not readable by the promise API. An unmeasurable entry counts as a document: wrong in the cheap direction.\n 3. A directory is not an unmeasurable file (Copilot). keys() yields directories; getFileHandle rejects TypeMismatchError, which the fail-open in (2) would have listed. Tested rather than argued -- the harness creates a real OPFS directory.\n\nIT ALSO ABSORBED THE JS TEST-INFRASTRUCTURE DECISION that PR #21 declined. playwright.config.js states that this is the one place a line of web/*.js is executed and why Playwright rather than a headless-DOM runner: what goes wrong in those files is a real Worker, a real WebSocket, real OPFS and real event ordering, none of which a DOM shim has. That decline now holds something.\n\nWHAT IT STILL CANNOT SEE: Safari (Playwright's WebKit provides no OPFS -- getDirectory() itself rejects; kept as a runtime PROBE-skip so it starts running the day that changes, and an unexpected skip on any OTHER engine FAILS as a regression). bindings.rs and web/worker.js as code paths.

Strictly tighter, and it retired the \"was anything rejected\" guard beside it.\n\nTHE ROOT CAUSE, which is the generalisable part and is now doctrine(a_derivation_correct_per_element_can_be_wrong_for_a_set): improvise-kmgs derived ModelCommand from the effects ONE AT A TIME and was right about every element -- but the key path never emits SetCell alone, it emits the PAIR with MarkDirty. So the wire got the mutation without its companion and no client edit ever marked the document dirty. When deriving a vocabulary from a set of primitives, ask what the existing callers COMPOSE, not only what each primitive is.\n\nTHREE BEHAVIOUR CHANGES CAME WITH IT, all recorded in the PR body:\n 1. Switching views, paging and stepping view history now mark the document dirty, so :q refuses after them. The user ruled this CORRECT -- Initial View and page selections are persisted, so discarding them silently was the bug, and :q! remains.\n 2. LoadModel leaves the document dirty, because it does not move file_path -- so the in-memory document really is a different one from the file the path names. A test pins the REASON, not just the flag.\n 3. A drill exited with no edits, and view-back, also mark it dirty -- a WRONG answer to no divergence, unlike (2).

Two coherent answers:\n * ADD Command::Save. But Save is genuinely ViewOnly and genuinely per-host -- a client asking a host to write to a path the client cannot see is a different thing from a client mutating the document, and it needs an answer for \"which path\" and \"what if there is none\" (improvise-lae already exists for the no-path case).\n * SAY EXPLICITLY THAT HOSTS OWN PERSISTENCE, and make each host trigger on its own terms. That is what improvise-9x6 did for the worker, and in a browser it is arguably RIGHT rather than a workaround: there is no file the user owns and no Ctrl-S semantics -- the document IS the OPFS entry.

The argument for the frame: a Command is something the shared state FOLDS, and saving mutates no shared state and no client's slice, so reduce_view had nothing to fold and Checked had no basis to answer for -- both arms were shims.

{"_type":"issue","id":"improvise-ondj","title":"[bug] reduce_full/apply_command apply a Command::Model without the basis check","description":"Found by the code review of ADR 001 layer 1 (2026-09-19). CONFIRMED, not live today, and it should be closed BEFORE the browser worker lands.\n\nui/reduce.rs is documented as \"the one place a command is applied to the authoritative state\" and \"Every deployment mode -- the native TUI, a websocket server, a browser worker -- reaches the model through the functions here\". Both pub fn apply_command and pub fn reduce_full accept a \u0026Command including Command::Model, and:\n\n    Command::Model { cmd, .. } =\u003e {          // the basis is DISCARDED by `..`\n        let effects = model_effects(app, cmd);\n        app.apply_effects(effects)\n    }\n\nThe check lives ONLY in Sessions::apply_model.\n\nWHY THIS IS THE INTERESTING SHAPE: making Command::Model a struct variant made the basis impossible to OMIT FROM THE MESSAGE. It did nothing to make it impossible to IGNORE ON ARRIVAL -- and `..` in a pattern is exactly the syntax for ignoring it, with no compile error. So the design got half of what a struct variant is usually reached for.\n\nNothing in-tree routes a client command through reduce_full (only tests), so nothing is broken now. But improvise-9x6 (the browser worker) is precisely the host that will reach for the function the module doc points it at, and it would apply client-supplied model commands unchecked.\n\nREMEDIES, pick deliberately:\n * Have apply_command take a ModelCommand from a private caller and expose only Sessions::apply for a wire Command -- makes the door unreachable rather than guarded.\n * Or have reduce_full return a Rejected-shaped result for Command::Model.\n * At absolute minimum, a compile-visible note AND a test that names the door, so the next person meets it.\n\nThe first is the one that matches this repo: invariants are made unrepresentable, not validated (doctrine(an_invariant_is_made_unrepresentable_not_validated)).","status":"closed","priority":1,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-20T01:05:13Z","created_by":"Edward Langley","updated_at":"2026-09-20T01:54:29Z","closed_at":"2026-09-20T01:54:29Z","close_reason":"Fixed as option 1 -- make the door unreachable -- but as a TYPE rather than as visibility.\n\napply_command and reduce_full now take Checked\u003c'a\u003e, a private-field newtype over a \u0026Command whose ONLY constructor is Checked::against(\u0026App, \u0026Command) -\u003e Result\u003cSelf, Rejection\u003e, which is also the only caller of stale_basis. So there is no longer a spelling of 'apply this batch and ignore what it claims': the  that discarded the basis is now a Rejection the caller must handle. Sessions::apply answers ONCE, before the dispatch, and hands the proof to apply_switch/apply_model -- so neither has to remember to ask, and apply_model lost its basis/model parameters entirely.\n\nWHY NOT pub(crate), which is what the ADR literally suggested: it works, but reduce_full then has NO non-test caller anywhere in the workspace, so it becomes a dead_code warning in the non-test build, and the only ways out are deleting a documented host API or cfg(test)-gating it. The newtype keeps both functions public and useful to a future host -- including the browser worker, which now gets a door that WORKS and is safe -- while making the unchecked path unconstructible. It also holds INSIDE the crate, which visibility does not: a second in-crate mutation path cannot be written without the check either.\n\nEVERYTHING THE TICKET SAID MUST SURVIVE, DOES: the check is still a property of the session door and not of every mutation (the key path, model_effects and App::apply_effects are untouched, and a host's own ModelCommand still needs no basis); caught_up(\u0026App, cmd) is unchanged and still not a bypass; the 10 basis_check tests are untouched and all pass.\n\nTHE REGRESSION GUARD IS THE SIGNATURE. The demonstration test (committed first, failed on the old code) NO LONGER COMPILES after the fix, which is the better outcome. What survives asserts that Checked::against returns Err(Rejection::LayoutMoved) and the document is untouched, with a doc-comment saying in prose that the signature is the real guard. Check-the-checker: making against() never refuse fails 8 tests -- the new one plus 7 of the 10 basis_check ones.\n\nNATIVE CLI EXERCISED FOR REAL, not merely compiled: improvise cmd and improvise script both land their changes on disk. They go through the keymap/registry path and never touched reduce_full.\n\nTHE THING THE TICKET DID NOT PREDICT, and it is the reason this defect could sit unnoticed: reduce_full HAS NO PRODUCTION CALLER IN THE ENTIRE WORKSPACE, and apply_command's view-slice arm is unreached outside tests. Every host reaches the model through Sessions::apply or reduce_key. So ui/reduce.rs's 'the signature the three hosts share' is ASPIRATIONAL -- a door pointed at by documentation and used by nobody, which is exactly the shape that hides a defect until the next host arrives.

DrillState holds an Rc, so it fails\nthe portability half of ViewState membership, and drill_state.pending_edits are\nuncommitted writes belonging to whoever staged them -- which is exactly why\nApplyAndClearDrill was REMOVED from ModelCommand (gotcha 38, improvise-tom1): a\nCommand::Model is routed with no SessionId, so an unaddressed\nApplyAndClearDrill lets client B commit client A's uncommitted typing.

Any wire form has to carry an order that is stable across processes.\n\nNote improvise-s8h7 (P1) is the user-visible symptom on the 'i' key and\nimprovise-l3hm (P3) is its sibling on CellId::Create. Both should close with or\nafter this, not before -- a louder refusal is not what the ruling asks for.\nUSER RULING 2026-09-21: \"The state drill manipulates (the view stack) should be local to the client.\"\n\nThis REDIRECTS the ticket. It had been scoped to the addressed command form (ADR 001 layer 2) -- a mutation carrying a SessionId. The ruling puts the view stack in the class of state this repo has ALREADY taken off the wire, which is a much cheaper shape.\n\nTHE PRECEDENT IS EXACT. Gotcha 38: ViewBack and ViewForward were removed from ModelCommand for precisely this reason -- \"their operand is ViewState::view_back_stack, session-local residue belonging to whoever navigated.\" And gotcha 29 records the earlier ruling that the model is shared and the UI is not, with ViewState::active_view already AUTHORITATIVE PER CLIENT; two clients may sit on different views of one document.\n\nWHAT IS SHARED AND WHAT IS NOT, on this reading:\n - the view stack, and which _Drill view this client sees: CLIENT-LOCAL (the ruling)\n - drill_state.pending_edits: already session-local residue (gotcha 30 -- holds an Rc, uncommitted writes belonging to whoever staged them)\n - the COMMIT: a genuine model change -- but as ordinary SetCell/ClearCell commands it is already on the wire, already basis-checked, and needs NO addressed form\n\nIf that holds, the SessionId-carrying mutation leaves this ticket entirely and ApplyAndClearDrill never returns to the wire -- which is what gotcha 38 removed it for.\n\nTHE OPEN QUESTION, and it may be the real work: a client has no Model. Entering a drill needs the record set for a cell, which is GridLayout::drill_records(r, c) and is server-side. So either the server PROJECTS the drilled record set -- the \"enrich the projection rather than move resolution back\" answer gotcha 47 already prescribes -- or a client cannot compose a drill locally at all. Settle that first; it decides whether this is a projection ticket or something larger.\n\nTRAPS THAT SURVIVE EITHER SHAPE:\n - gotcha 1: pending edits are keyed by (row, RecordCol), and _Dim carries the column INDEX, not a label, because a category and a measure may share a name.\n - gotcha 18: a drill snapshot frozen in HASH ORDER made the same drill address DIFFERENT RECORDS in a second process -- silent misdirected writes. Whatever the client holds needs an order stable across processes.\n\nNote the view-back decline in resolve.rs says explicitly it is NOT \"not built\": it COMMITS A DRILL FIRST, so composing it in a browser would silently commit pending edits. Under the client-local shape that commit is the client's own to sequence, which removes the reason for the decline rather than working around it.\nUSER RULING 2026-09-21 (second): \"Drilling should be an ephemeral view, not something that gets persisted.\"\n\nHALF OF THIS ALREADY HOLDS, and the other half is the work. Verified at 523d571:\n\n - NOT PERSISTED: already true. VIRTUAL_VIEW_NAMES is [\"_Records\", \"_Drill\"] (core/src/view/types.rs:14). Both are never written and are dropped on load if an older file carries them; saving from drill mode writes the first real view as Initial View.\n - BUT IT IS SHARED: DrillIntoCell (command/cmd/grid.rs:348) builds the _Drill view and puts it in the WORKBOOK's views map, which is shared document state. So today drill is ephemeral with respect to the FILE and not with respect to other CLIENTS.\n\nTAKEN WITH THE FIRST RULING -- that the view stack is client-local -- the consequence is that _Drill should not be in Workbook::views at all. It is a client-side construct: built by the client that drilled, seen by nobody else, and discarded when that client leaves it. \"Ephemeral\" and \"client-local\" are the same statement viewed from the file and from the session.\n\nWHAT THAT BUYS, and why it is cheaper than the addressed command form this bead originally proposed:\n - no SessionId-carrying mutation is needed for the view itself\n - ApplyAndClearDrill never returns to the wire, which is what gotcha 38 removed it for\n - the view-back decline stops needing a workaround: its comment says it is not \"not built\" but that it COMMITS A DRILL FIRST, and a client that owns its own stack sequences that itself\n\nWHAT THE SERVER STILL OWES, which is the open question: DrillIntoCell captures a RECORDS SNAPSHOT at drill time (grid.rs:365 onward, \"Capture the records snapshot NOW\"), built from ctx.model.data -- which a client does not have. So either that snapshot is projected, or a client cannot compose a drill. gotcha 47's rule applies: enrich the projection rather than move resolution back.\n\nNote gotcha 10 while you are here: drilling a FORMULA cell strips the _Measure coordinate when it names a formula target, or matching_cells returns nothing instead of the raw records. Whatever composes a drill has to keep that, and a client does not know which measures are formula targets unless told -- another thing the projection may owe.\n\nAnd gotcha 18's warning is sharpened by \"ephemeral\": the snapshot is frozen at drill time and pending_edits are keyed by ROW INDEX into it, so the order must be stable for as long as the drill lives, even though the drill itself is not.\nUSER RULING 2026-09-21, answering the product question PR #115 left open: \"The staging scheme should be identical, because they're solving different problems.\"\n\nTHE QUESTION IT ANSWERS. The agent proposed that a browser could WRITE THROUGH with ordinary SetCell commands instead of staging, on the grounds that those are already basis-checked. The ruling rejects that, and the reason is the important part: BASIS-CHECKING AND STAGING SOLVE DIFFERENT PROBLEMS, so the first does not substitute for the second.\n\n - the basis check is ANTI-STALENESS COORDINATION between clients. It answers \"is your picture of this record current\" (ADR 001, gotcha 43). It is explicitly NOT a security boundary and explicitly not about intent.\n - staging is an EDITING-SESSION abstraction for one user. It answers \"does this person want to keep what they just typed\" -- several edits accumulate and commit atomically on leaving, or are discarded on cancel.\n\nWrite-through would have silently removed the ability to ABANDON a drill. That is a user-facing capability, not an implementation detail, and losing it is not visible in any test that only asks whether an edit lands.\n\nSO: the browser stages, identically to the TUI. DrillState::pending_edits becomes client state -- which is consistent with the other two rulings rather than in tension with them, since the view stack is client-local and drill is an ephemeral view. All three say the same thing: a drill is one person's transient workspace.\n\nTHE CONVERGENCE WORTH NOTING, because it makes the commit cheap: clause 4 IS NOW DELIVERED (improvise-yqpd). ClientFrame::Commands is answered whole and applied whole -- CheckedBatch::against checks the frame before anything runs, and a failure rolls the document, the mirrors and the session slice back. So a staged drill's commit is a BATCH OF SetCells and gets its atomicity from the transaction that already exists, with no new mechanism. Before clause 4 that batch could have half-applied, which is precisely the partial-and-silent failure a staged commit must not have.\n\nTWO THINGS THE COMMIT STILL NEEDS, from the same PR's findings:\n - the category-column arm has NO ModelCommand. ApplyAndClearDrill's RecordCol::Category(_) path is apply_coordinate_rename -- add an item, then move EVERY measure cell in the row (gotcha 1) -- and no wire variant exists for it. Filed separately.\n - gotcha 18's order warning binds the staging, not just the snapshot: pending_edits are keyed by ROW INDEX into a frozen list, and a list frozen in hash order made the same drill address DIFFERENT RECORDS in a second process. Client-side staging inherits that requirement exactly.\nTRAP OPENED BY PR #117 (improvise-cfly), found in orchestrator review 2026-09-22.\n\nThe browser's view-back resolver emits [Command::ViewBack] where the TUI's\nViewNavigate{forward:false} emits [ApplyAndClearDrill, ViewBack]. That omission is\ncorrect TODAY only because a browser cannot stage a drill: drill-into-cell is\ndeclined, and edit_or_drill's CellId::Aggregate arm answers with a sentence.\n\nWHEN THIS TICKET LANDS, THAT STOPS BEING TRUE AND NOTHING FAILS. Stepping back in\na browser would silently discard staged drill edits that the TUI commits -- a\ndata-loss divergence, invisible across the whole suite.\n\nWorse, the guard points the wrong way.\nresolve::tests::the_view_history_keys_answer_in_both_directions asserts the arm\nemits EXACTLY vec![Command::ViewBack], so it PINS the current behaviour rather\nthan guarding the transition. It keeps passing while the bug exists, and a change\nthat FIXED the bug would fail it.\n\nSO THIS TICKET'S ACCEPTANCE GAINS A CLAUSE: making drill reachable in a browser\nmust also answer what stepping back does with staged edits, and must change that\ntest rather than work around it.\n\nRecorded here rather than as its own bead because the addressed-command form this\nticket is about is exactly what makes ApplyAndClearDrill expressible at all\n(gotcha 38 / improvise-3x3u) -- they are the same piece of work, and a separate\nbead would sit unread until someone hit the bug.","status":"closed","priority":1,"issue_type":"task","owner":"el-github@elangley.org","created_at":"2026-09-20T00:18:34Z","created_by":"Edward Langley","updated_at":"2026-09-23T01:37:03Z","closed_at":"2026-09-23T01:37:03Z","close_reason":"Decomposition landed in PR #140 (ViewStep/records_spine/records_steps/drill_steps in improvise-core; cmd/grid.rs keeps only steps_into_active_view).

In\n    render_state: {\"Aggregate\":\"750ab1f5ffa96d5e00f605b3c8e36aac\"}.\n  - render.rs::editable correctly answers false for it (ADR 002), so the page\n    offers no editor on an aggregate.\n  - resolve.rs reaches the CellId::Aggregate arm of edit_or_drill.\n  - The TUI path is intact: 12 drill tests pass across cmd/grid.rs, cmd/mode.rs,\n    ui/effect.rs and ui/app.rs.

The user sees why.\n\n  - `\u003e` (drill-into-cell) is SILENT. It is a command name resolve::step does not\n    handle, so it falls through to KeyOutcome::Upstream -\u003e ClientFrame::Key -\u003e\n    Host::handle, whose Key arm is an explicit `Vec::new()`. Gotcha 47: an\n    upstream key is a black hole, not a slow path. Pressing `\u003e` produces no\n    status, no mode change, nothing at all.\n\n`\u003e` is the key the help hint advertises for drill (\"\u003e:drill\" in the Normal-mode\nhint line), so the advertised gesture is the silent one and the honest refusal\nis on a key the user was not told to press.

Gotcha 46 puts exactly one category on each visible axis\nprecisely so every cell is a Record, and tests/web_demo_model.rs asserts it.

Three envelope vocabularies for two deployments become ONE pair: improvise-protocol::frame owns ClientFrame { Viewport, Command, Key } and ServerFrame { Snapshot, Commands(Vec\u003c_\u003e), Rejected }; improvise-ws-server and improvise-wasm-client each pub use them and neither defines one. Both wire.rs files DELETED.\n\nTHE QUESTION THE TICKET SAID TO DECIDE FIRST -- do the worker and the socket want the same vocabulary -- IS ANSWERED YES, and the test applied to each difference was whether the ARGUMENT for it names the thing they differ in. None did:\n * Viewport is deployment-independent. Its justification is that the extent is a fact about a terminal or a browser window, is not in ViewState, and no effect produces it, so no derivation reaches it. Nothing transport-shaped. Its handshake role is a property of GridCache::seed (a Snapshot seeds the VISIBLE cells), not of sockets. A worker hosting the same Sessions owes set_extent the same answer.\n * Key is deployment-independent. Its justification (gotcha 38) is that a binding names an INTENT resolved against a CmdContext a thin client does not hold -- which says nothing about what the bytes travel over. Decisive evidence: the wasm client ALREADY PRODUCES a Key frame on both paths and tests/lockstep.rs round-trips it. So the socket's 'no Key' was never a statement about the socket, it was an unfinished feature (improvise-bpq2) that the separate envelope made invisible.\n * Commands(Vec\u003c_\u003e) vs Command(_): the batching is a property of the FOLD, not the transport -- a fan-out must arrive whole and in sequence because a cell update that overtakes its labels is DROPPED (gotcha 33), and an in-process postMessage interleaves exactly as a socket does. Commands(vec![c]) expresses everything the singleton could; the reverse is false.\n\nAND THE WORKER PAIR WAS INCOHERENT, NOT MERELY DIFFERENT -- the strongest evidence its differences were staleness. Written before ADR 001, it could carry Command::Model { basis, .. } and had NO Rejected variant, so a client speaking it composed a claim that could never be answered. It was missing a variant its own payload type demands.\n\nA FIND THE TICKET DID NOT PREDICT: the worker envelope was NOT 'unused by anything'. It was the return type of Client::set_cell/set_cell_at/key/on_key_event and the input to apply/handle_message/on_message. The wasm client was carrying TWO PARALLEL FOLD SURFACES OVER ONE STATE, identical except that the worker one had no Rejected arm. Once the envelopes unified they were literal duplicates, so the worker trio is deleted; web/app.js calls neither.\n\nBOTH MIRROR TESTS DELETED, which was the stated measure of success. What they checked is now TYPE IDENTITY: a rename is a compile error at every call site in both crates, and 'a variant added on one side and not the other' is not a constructible state. Strictly stronger than a hand-written fixture list. The check-the-checker MOVES rather than dies -- the_retired_spellings_do_not_parse keeps the injected-fault discipline and aims it at the one thing still possible, the retired Bootstrap/Command spellings returning as serde ALIASES, which would be two homes again wearing one type. End-to-end compatibility is now browser_round_trip.rs handing the wasm client's own serialized frame to a real Host::handle.\n\nHost::handle gains an explicit ClientFrame::Key =\u003e Vec::new() arm.

{"_type":"issue","id":"improvise-bpq2","title":"Client-side key resolution: what must the projections carry?","description":"USER RULING (2026-09-19): keys are converted into commands IN THE BROWSER; the keymap is a client-only concept the server must not know. Follows from the standing principle -- the model is shared, the UI is not, and a keymap is UI. It also buys something real: two clients may have DIFFERENT bindings over the same document, which is impossible if the server owns the keymap.\n\nThis inverts improvise-gsw conclusion (which had keys travelling upstream unresolved) and closes the keypress-door ticket. The work is now to make client-side resolution POSSIBLE.\n\nTHE PROBLEM TO SOLVE. A binding names an INTENT resolved against a CmdContext -- Model, GridLayout, cursor, yanked cell, expanded cats, mode. A Command is the RESOLVED MUTATION, e.g. SetSelected { row, col }. A thin client holds ViewState plus the widget caches. So for each binding ask: can a client holding only that state compose the Command? Where the answer is no, the fix is to ENRICH THE PROJECTION, not to move resolution to the server.\n\nKNOWN GAPS, from the gsw agent own analysis of what it could not resolve:\n * CURSOR MOVEMENT -- GridCache is indexed by position WITHIN THE VIEWPORT, so a client cannot distinguish \"last visible row\" from \"last row\" and cannot clamp. It needs the total row/col count, or an explicit \"can I move further\" fact.\n * PANEL CURSOR MOVEMENT -- move-panel-cursor walks a flattening that depends on expanded_cats. Either the cache carries the flattened list, or the client re-derives it -- and re-deriving is how two ends drift.\n * MODIFIED CHARACTERS -- KeyPattern::AnyChar matches a Char under ANY modifiers on the host. A client mirroring that is fine now that the client owns the keymap outright; the old constraint (local resolution may only ever be a strict subset) DISSOLVES once there is no host keymap to be a subset of.\n\nMETHOD: enumerate the bindings, not the commands -- the keymap is the thing being made client-side, so walk it. doctrine(binding_dump_diff) already says most bindings have no direct test, so a green suite is not evidence here either.\n\nALSO IN SCOPE: move ClientMessage/ServerMessage into improvise-protocol. The vocabulary is there and the framing that says which a JSON blob is, is not; the ws-server will want the same envelopes and two crates should not define them.\n\nBlocks improvise-1ey.","notes":"\n--- THE COMPOSABILITY LIST (improvise-q08 agent, 2026-09-19) ---\nWhich Commands a thin client holding ViewState + the five widget caches CANNOT compose. This is the real content of this ticket.\n\nHARD BLOCKERS:\n1. SetCell { key: CellKey } and ClearCell(CellKey) -- THE BIG ONE, and it blocks\n   the most basic action there is. A client sees a grid of LABEL STRINGS indexed\n   by viewport position. A CellKey is the full sorted coordinate tuple: every Row\n   and Column category, plus every Page AND Filter selection (gotcha 27). Nothing\n   in GridCache says which category a row label belongs to; nested row axes\n   flatten several categories into one label; the page/filter constraints are not\n   projected at all; and records mode encodes a COLUMN INDEX in _Dim (gotcha 1).\n   There is no client-side derivation. NOTE THIS BLOCKS improvise-1ey DIRECTLY --\n   its stated scope is \"type a number into a cell and see the value update\".\n2. ToggleGroup { category, group } and AddItemInGroup -- CategoryRow.items is a\n   flat Vec\u003cString\u003e; groups, group membership and collapsed state are not\n   projected. The server does the cat_tree flattening.\n3. RemoveFormula { target, target_category } -- FormulaCache is Vec\u003cString\u003e of RAW\n   text. The client would have to re-parse to get target (dragging\n   improvise-formula into a thin client), and target_category is simply absent, so\n   a formula written [CustomCat] cannot be addressed at all.\n4. LoadModel(PathBuf) / ImportJsonHeadless -- paths name documents in the HOSTs\n   Storage (gotcha 2) and nothing projects a listing, so a client cannot compose a\n   path it has reason to believe exists.\n5. ApplyAndClearDrill / AcceptWizardModel -- nullary so constructible, but nothing\n   projects drill or wizard state, so a client cannot know when either is\n   meaningful. (Both are already off the wire per improvise-3x3u.)\n\nCOMPOSABLE BUT TRAPPED:\n* SetSelected { row, col } is ABSOLUTE; GridCache is VIEWPORT-RELATIVE. The client\n  must add row_offset/col_offset from its own ViewState -- it has them, but the two\n  index spaces are not distinguished by any type and getting it wrong is silent.\n* The grids TOTAL row/column count is not projected, so a client cannot clamp its\n  cursor or size a scrollbar.\n\nFINE TODAY: SetAxis/CycleAxis/TransposeAxes/TogglePruneEmpty/SortData/\nCleanEmptyRecords, AddCategory/RemoveCategory, AddItem/RemoveItem/HideItem/\nShowItem/SetPageSelection WHEN DRIVEN FROM THE CATEGORY PANEL (not from the grid\ncursor -- same reason as 1), CreateView/DeleteView/SwitchView/ViewBack/ViewForward,\nAddFormula, SetNumberFormat (though the CURRENT format is in no cache, so it cannot\nbe pre-filled), and the whole view half.\n\nSUGGESTED ORDER: item 1 first and alone -- it is what 1ey needs and it is a\nprojection design question (how does a client name a cell?), not a plumbing one.\n\n--- ADR 002 ACCEPTED (user, 2026-09-19): see context/adr/002-naming-a-cell.md ---\nA projected cell carries an OPAQUE SURROGATE KEY, and its ABSENCE means the\ncell is an aggregate:\n    CellDisplay { text, numeric, error, key: Option\u003cCellId\u003e }\nSome -\u003e a stored cell this client may set, named by a token it echoes back.\nNone -\u003e an aggregate: drill, do not set.\n\nWHY THE NULLABILITY IS THE POINT: a client cannot compose SetCell for an\naggregate because there is NO KEY TO PUT IN IT. That is make-invalid-states-\nunrepresentable (design-principles 3), strictly stronger than a server-side\nrejection. It also mirrors a fork the model ALREADY makes -- EditOrDrill in\ncmd/mode.rs branches on exactly this -- so the wire projects an existing\ndistinction rather than inventing one. And it follows the precedent\nCellDisplay::numeric set, whose doc says the server decides \"because it is the\nside that knows\".\n\n_INDEX WAS CONSIDERED AND REJECTED, and the reason is worth keeping: right\nontology, unsafe representation. CategoryKind::VirtualIndex is documented as\n\"Items are 0, 1, ... N where N = number of matching cells\" -- POSITIONAL over\nthe currently matching set, not an identity. _Index = \"3\" names a different\nrecord after a filter change, an insert or a delete, and a different one again\nin another view. A client echoing a stale _Index writes to the WRONG CELL,\nSILENTLY -- worse than a surrogate that fails to resolve, and the same hazard\nclass as viewport-relative-vs-absolute and the stale cursor under a renamed key.\n\nBUT KEEP WHAT IT POINTS AT: the surrogate should name the RECORD, not the cell.\nA record is the coord tuple minus _Measure (record_row_identity), which is\nalready ADR 001 unit of atomicity and already what record_versions is keyed by.\nAddress a cell as (record surrogate, measure) and ONE IDENTITY serves both\naddressing and staleness, instead of each ADR inventing its own.\n\nOPEN, for the implementer to decide with evidence: hash vs interned id (the\ncodebase interns Symbols already); how the server resolves a surrogate back --\nnote that REGENERATING FROM THE CURRENT LAYOUT means a stale surrogate simply\nfails to resolve, which IS ADR 001 stale-basis rejection at cell granularity,\nso the two compose; and what DRILL addresses with, which this does not answer.\n\n--- SURROGATE DECIDED (user, 2026-09-19): hash of the normalized record, maintained as an index ---\nNOT a hash of the cell -- of the RECORD (the coord tuple minus _Measure), which\nis already ADR 001 unit of atomicity and already what record_versions is keyed\nby. A cell is (record hash, measure).\n\nWHY: it makes stale edits cheap to identify, three ways at once. The surrogate\na client already holds IS the lookup key for its own version, so record_versions\nbecomes HashMap\u003cRecordHash, u64\u003e -- fixed size, no allocation, no CellKey\nreconstruction on the hot path. A basis is a list of (record hash, version)\npairs: compact on the wire, O(1) to check. And a record that no longer exists\nsimply fails to resolve, so that whole class of staleness needs no version\ncomparison at all.\n\nIt is well-defined because CellKey ALREADY has a canonical form -- CellKey::new\nsorts by category name and equality/hashing rely on it (gotcha 5). Normalized\nmeans that form with _Measure removed; the normalization is a property the type\nguarantees, not a new convention.\n\nRESOLUTION IS A MAINTAINED INDEX, IN DataStore -- a hash is one-way, and\nregenerating from the layout would be O(visible cells) per resolve AND would\nonly cover the visible window, while a client may hold a surrogate for a record\nthat scrolled away. DataStore is the right home: it already interns every name\ninto a SymbolTable and already maintains HashMap\u003c(Symbol,Symbol), HashSet\u003cInternedKey\u003e\u003e\nfor hot-path lookups. The RecordHash index is the same shape, updated at the same\npoints, and that existing (Symbol,Symbol) index is what makes INVALIDATION\ntractable -- when a category or item disappears, the records mentioning it are\nfindable without a scan.\n\nTWO THINGS THAT FALL OUT: the index and record_versions want to be ONE structure\n(RecordHash -\u003e (record, version)) since both are keyed the same and invalidated\ntogether, giving both ADRs their answer in one lookup. And structural vs data\nstaleness separate cleanly: does not resolve = the record is GONE (reject,\nnothing to write to); resolves with a differing version = the record CHANGED\n(reject as stale, offer force). Regenerating from the layout would have\nconflated those, because a record scrolled out of view would look identical to\none that no longer exists.\n\nTHREE SILENT-BREAKAGE TRAPS, each producing a WRONG WRITE rather than an error:\n * NOT DefaultHasher / RandomState -- randomly seeded PER PROCESS, so hashes\n   would differ across a restart and between processes.\n * NOT #[derive(Hash)] as the definition -- Rust guarantees no stability across\n   compiler versions or platforms. Hash an explicit BYTE SERIALIZATION of the\n   sorted (category, item) pairs.\n * Pick the WIDTH BY CONSEQUENCE: a collision is a silent write to the wrong\n   record, which is exactly why _Index was rejected. 64 bits hits birthday risk\n   near 2^32 records; 128 bits costs 8 more bytes per VISIBLE cell (~8KB on a\n   50x20 viewport). Argue it, do not default to u64 for convenience.\n\n--- CellId IS A TWO-VARIANT ENUM (user, 2026-09-19), not Option ---\n    enum CellId { Record(RecordHash), Aggregate(AggregateHash) }\nSetCell takes a Record and nothing else; Drill takes an Aggregate and nothing\nelse. An aggregate surrogate is a hash of its COORDINATE CONSTRAINT -- the row\nand column coordinates plus page/filter selections -- so it costs one hash per\ncell, the same width and the same DataStore index as a record.\n\nWHY NOT Option\u003cCellId\u003e with None meaning aggregate: an aggregate is NOT the\nabsence of an identity, it is a different KIND of identity. Option made SetCell\nsafe and left Drill with nothing to address, which is exactly how drill\naddressing became an open question. Two variants close it by construction and\nmake BOTH operations unrepresentable-if-wrong rather than just one.\n\nDEFERRED, filed separately: shipping a bounded keyset per aggregate for hover\npreviews. The unbounded version is untenable -- the payload would scale with the\nDATA while the rest of a projection scales with the VIEWPORT, ~16MB to render\n1000 cells over a million-record document -- and drill-on-demand works without\nit.\n\n--- ADR 002 SPINE LANDED (2026-09-19). What remains here is the KEY RESOLUTION half. ---\nMerged: RecordHash/AggregateHash, the record index in DataStore, CellId on\nCellDisplay, SetCell/ClearCell taking a surrogate, and Client::set_cell /\nset_cell_at in the wasm client. 1017 tests, 16 faults injected and all fired.\n\nSO A CLIENT CAN NOW COMPOSE A WRITE -- improvise-cr3 can call set_cell_at\ntoday. What is NOT done, and is this ticket own subject: WIRING IT TO A\nKEYSTROKE. The wasm client still forwards editing keys upstream unresolved,\nwhich is exactly the thing the user ruling (keymap is client-only) says must\nchange. The composability list earlier in these notes is still the map; item 1\n(SetCell) is now answered, items 2-5 are not.\n\nDECISIONS THE IMPLEMENTER MADE THAT ARE WORTH KNOWING:\n * The wire form of a surrogate is a 32-char HEX STRING, not a number. serde_json\n   writes u128 as a bare number and a JavaScript host parses every JSON number as\n   f64, so anything above 2^53 comes back CHANGED. This trap was not in the ADR.\n * CellId::Record carries RecordCell { record: RecordHash, measure: Option\u003cString\u003e },\n   not a bare hash. The ADR says both \"hash the record\" and \"a cell is (record\n   hash, measure)\"; both cannot hold if the hash covers the measure, because then\n   record_versions could not be keyed by it -- which is the reason the ADR chose\n   the record over the cell. Carrying the measure beside the hash satisfies both.\n * id: None is NOT \"aggregate\" (that is Some(CellId::Aggregate)). It means no\n   projected cell: a padded/invalidated GridCache slot, or a records-mode\n   COORDINATE column, which renames across the whole row (gotcha 1) and is a\n   different intent from SetCell.\n * A zero cell count is a TOMBSTONE, not a removal -- dropping the entry would let\n   a delete-and-recreate reset the version to 0, so a client holding version 0\n   against the OLD record would be told its basis is current and its write\n   applied. resolve_record filters on liveness; record_version reads through.\n * Resolution is INDEX FIRST, LAYOUT SECOND. The index covers every record holding\n   data on screen or not; the layout answers cells with NO DATA YET -- and typing\n   into an empty cell IS improvise-1ey.","status":"closed","priority":1,"issue_type":"feature","owner":"el-github@elangley.org","created_at":"2026-09-19T23:42:49Z","created_by":"Edward Langley","updated_at":"2026-09-20T02:36:27Z","closed_at":"2026-09-20T02:36:27Z","close_reason":"Done for the cursor half, with a named list of what still needs the host so closing the rest has to come here and say so.\n\nTHE FINDING THAT REFRAMED THE TICKET: Host::handle answers ClientFrame::Key with an EXPLICIT EMPTY VEC, so an upstream key is a BLACK HOLE, not a slow path. Combined with the improvise-9x6 finding (nothing in the projection stream carries the host's ViewState, so host-side resolution DIVERGES), every KeyOutcome::Upstream was a binding that does nothing at all in a browser. That turns the ticket's measure into simply 'how much of the keymap can the client answer'.\n\nMETHOD WAS THE TICKET'S: walked KeymapSet::default_keymaps() -- all 16 modes, ~170 bindings -- via a throwaway dump test, per doctrine(binding_dump_diff). Resolved client-side now: hjkl/arrows, 0/$/Home/End, G, PageUp/Down, Ctrl-d/Ctrl-u, panel cursor, tile cursor. ~15 more need NO enrichment and were deliberately left rather than half-done.\n\nTHREE PROTOCOL ADDITIONS, each argued as the smallest thing:\n * GridExtent { rows, cols } via GridUpdate::Extent -- the ticket's gap 1. Deliberately NOT framed by the labels: it is the size of the grid the labels are a window ONTO, so fit_to_labels leaves it alone and its batch position is not load-bearing (it addresses no position, so it can neither overtake nor be overtaken). The producer reads GridLayout::row_count()/col_count(), never the projected ranges -- reading it off the ranges is INVISIBLE IN THE TUI, which builds at offsets zero, and is exactly the browser bug.\n * ClientFrame::Command -\u003e Commands(Vec\u003cCommand\u003e). FORCED: one cursor key is SetSelected plus up to two scroll offsets, and a host that folds the selection but not the offset projects the wrong window. Same argument ServerFrame::Commands already carried.\n * ClientState::window (session-local) + Client::set_viewport. NOT DERIVABLE: row_labels.len() is the window CLIPPED to the grid, which equals the window everywhere except the bottom edge -- exactly where the scroll arithmetic matters. Nothing added to ViewState; both gating tests hold; transient_prefix untouched.\n\nTWO CORRECTIONS TO THE TICKET'S OWN GAP LIST:\n * Panel cursor movement WAS NEVER A GAP. improvise-edp already made viewmodel::flatten_cat_tree the one home both ends call, so calling it is the SHARED derivation, not a second one. Nobody had noticed. Worth checking other old 'known gaps' against what has landed since.\n * The unmodified-characters rule was MIS-SCOPED, not wrong. It was about KeyPattern::AnyChar, which is bound ONLY in the text-entry modes; in Normal there is no such fallback, so Ctrl-d has an exact binding and mirroring it is a faithful subset. Kept where it was earned, dropped where it was never true.\n\na_key_resolved_on_the_host_moves_state_no_client_can_hear STILL HOLDS and was not flipped -- it states a true property of host-side resolution, which bpq2 now AVOIDS by construction rather than contradicts.\n\nEach resolver mirrors its Cmd LINE FOR LINE, including where siblings disagree about a no-op move (Move and MoveTileCursor emit anyway; MovePanelCursor does not). Unifying them would make the client a second derivation, which is what lockstep testing exists to rule out.\n\nSIX INJECTED FAULTS, ALL FIRED. The five new lockstep tests build the client's cache with the server's OWN grid_of, drive client and real reduce_key over the same keypresses, and compare ViewState. nothing_in_a_non_text_mode_resolves_locally became FALSE and was replaced by a named list of the Normal-mode keys that still need the host.\n\nSTILL NEEDS THE HOST, truthfully: all prefix keys (transient_prefix is an address, not a keymap -- gotcha 13, left intact); save/wq/commit-export (Storage by definition); : execute-command; the wizard's Any binding (WizardCache has no Projection by design); CommandMode Backspace; enter-advance (its AbortChain is a fact about the effect chain, not a cursor); records/drill toggles (session-local residue).\n\nOrchestrator applied the one line the agent flagged and could not make: web/app.js now calls client.set_viewport rather than the associated Client.viewport, without which the client never learns its window and every cursor key vanishes upstream.\n\n1172 passing, clippy/fmt clean, wasm32 clean on all seven bundle crates.","dependency_count":0,"dependent_count":0,"comment_count":0}

{"_type":"issue","id":"improvise-9x6","title":"Worker-hosted server bundle (wasm, MessageChannel transport)","description":"New wasm bundle that hosts the full App + command pipeline + projection layer + VFS persistence inside a browser worker. Communicates with the main-thread side via a MessageChannel carrying Command messages in the same shape as the websocket protocol. The worker-server is the 'server' half of the standalone deployment — structurally it mirrors improvise-ws-server but swaps tokio + tungstenite + std::fs for wasm + postMessage + OPFS. Both ws-server and worker-server reuse the same projection layer (improvise-cqq); only the transport and persistence backend differ.","design":"crates/improvise-worker-server/. Depends on improvise-core, improvise-formula, improvise-command, improvise-io (persistence half), improvise-protocol, and the OPFS Storage implementation from improvise-i34. wasm-bindgen entry points: init(opts) initializes App and VFS-backed Storage, loads an initial file from OPFS if present; on_message(serialized_command) deserializes the Command, feeds it through the App + projection layer, posts any outbound projection commands back via self.postMessage(). OPFS is async; handle by returning JsPromise from on_message or by queuing outbound messages and letting the event loop deliver them. Projection layer (improvise-cqq) is reused wholesale — transport-agnostic, already tracks per-session viewport state. The only new code specific to this issue is (a) wasm-bindgen bootstrap, (b) MessageChannel binding via self.onmessage / self.postMessage, (c) wiring VFS/OPFS storage into the persistence layer. Worker choice: Dedicated Worker first. Service Worker later if PWA install is desired.","acceptance_criteria":"(1) Crate compiles to wasm32-unknown-unknown. (2) Worker bundle runs the full App end-to-end: loads file from OPFS, processes commands, persists changes, emits projections. (3) Size budget: under 3 MB compressed. (4) Driven by a test harness that simulates main-thread postMessage traffic.","notes":"Companion to improvise-djm — two halves of the standalone deployment. Depends on improvise-cqq (projection layer), improvise-cqi (protocol), improvise-ywd (wasm compat), improvise-6mq (VFS abstraction), improvise-i34 (OPFS impl). Effectively a wasm-flavored analogue of improvise-q08 (ws-server); both wrap the same projection layer with a different transport + persistence.","status":"closed","priority":1,"issue_type":"feature","owner":"el-github@elangley.org","created_at":"2026-04-14T07:39:29Z","created_by":"spot","updated_at":"2026-09-20T02:10:39Z","closed_at":"2026-09-20T02:10:39Z","close_reason":"Done. The server as a wasm blob in a Web Worker: same App, same Sessions, same Host, behind self.onmessage/self.postMessage with OPFS underneath. Closed with --force because the graph still lists improvise-xf1 (browser verification of OpfsFs), which is DEFERRED by user decision -- that block is waived, not satisfied.\n\nAC 1 met (wasm32 clean, builds through wasm-pack, added to the CI wasm job). AC 3 met with room: 1,334,892 bytes raw / 496,965 GZIPPED plus 6,700 of JS glue -- about 492 KB against a 3 MB budget; with the client's unchanged 122,599 the pair is ~600 KB. AC 4 met: tests/post_message.rs drives a real Worker with nothing but the JSON a MessagePort carries.\n\nAC 2 IS MET HOST-SIDE, NOT BROWSER-SIDE, and the line is exact. Tested: worker.rs (16t), vfs.rs, post_message.rs (6t) -- handshake, Addressed filter, rejection path, persist trigger, seeding and list are all on this side. Untested: bindings.rs (cfg wasm32) and web/worker.js -- compile-checked, node --check-ed, all three calls confirmed in the generated .d.ts with matching arity, nothing more. createSyncAccessHandle exists in no harness, so OPFS ITSELF REMAINS NEVER RUN: if persistence misbehaves in a browser it is the first place to look.\n\nHOST WAS MOVED, NOT MIRRORED -- the one non-additive call, sanity-checked at merge. Host is App + Sessions + handle, contains no socket, and lived in a tokio crate the worker cannot depend on. It now lives in improvise_command::ui::host beside Sessions; ws-server re-exports so every path resolves; registry stayed behind because a worker hosts ONE document. Re-implementing the loop would have been the mirror improvise-xks6 had just deleted for the frames, and a drifting Applied/Broadcast match is invisible until a client sees it. Verified at merge: host.rs imports only crate::ui::{app,project} and improvise_protocol, and improvise-command's dependency list is unchanged.\n\nTHE DOCUMENT IS NAMED OUT OF BAND, in the worker's URL -- the analogue of the socket naming it in the ws:// path. NO FOURTH ClientFrame. Per the user's ruling mid-flight, loading is THE VFS, not a bespoke entry point: a seed is a Storage::write read back like any other document, so a fetched demo, an upload and a saved file share one parse path and a seed never clobbers an edit.\n\nClientFrame::Key IS LEFT ANSWERING NOTHING, and the brief's premise that a worker could resolve it was WRONG for a reason worth keeping. A worker CAN call reduce_key; the blocker is downstream and identical on both transports -- NOTHING IN THE PROJECTION STREAM CARRIES THE HOST'S OWN ViewState. A client's slice moves only by folding Commands, and project emits document projections, a grid diff and a basis, none of which is a mode or cursor change. So resolving a key host-side does not under-deliver, it DIVERGES: the host believes it is in Editing while the client draws Normal, and viewport() reads the mirror's cursor so the grid would not even scroll. That is improvise-bpq2, now a DEMONSTRATED property rather than prose -- a_key_resolved_on_the_host_moves_state_no_client_can_hear fires reduce_key against a real App and asserts the mirror did not follow.\n\nFOUR REAL OBSTACLES, AND NONE WAS OPFS: Host in the wrong crate; Save unreachable from the wire; dirty never set by a wire edit; the async seam unreachable through a Box. THREE OF THE FOUR ARE GAPS IN THE SHARED LAYER THAT THE SOCKET SERVER HAS TOO -- it never noticed, because its documents are opened from a CLI and saved by a human pressing a key in a TUI that is not there. Filed separately. Being the second real consumer of an abstraction is what audits it.\n\n1155 passing (+22), clippy/fmt clean, wasm32 clean on all SEVEN bundle crates, actionlint clean. Delivery stayed cheap: two lines in build.sh, one cp -rf plus one cp in the assemble step.","dependencies":[{"issue_id":"improvise-9x6","depends_on_id":"improvise-6mq","type":"blocks","created_at":"2026-04-14T00:40:12Z","created_by":"spot","metadata":"{}"},{"issue_id":"improvise-9x6","depends_on_id":"improvise-cqi","type":"blocks","created_at":"2026-04-14T00:40:11Z","created_by":"spot","metadata":"{}"},{"issue_id":"improvise-9x6","depends_on_id":"improvise-cqq","type":"blocks","created_at":"2026-04-14T00:40:10Z","created_by":"spot","metadata":"{}"},{"issue_id":"improvise-9x6","depends_on_id":"improvise-i34","type":"blocks","created_at":"2026-04-14T00:40:13Z","created_by":"spot","metadata":"{}"},{"issue_id":"improvise-9x6","depends_on_id":"improvise-xf1","type":"blocks","created_at":"2026-08-31T23:11:01Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-9x6","depends_on_id":"improvise-ywd","type":"blocks","created_at":"2026-04-14T00:40:12Z","created_by":"spot","metadata":"{}"}],"dependency_count":6,"dependent_count":3,"comment_count":0}
{"_type":"issue","id":"improvise-bck","title":"Standalone web MVP: end-to-end offline demo","description":"Final milestone of the standalone epic. Open the deployed static site (or run it locally from file://), load a bundled demo .improv file, edit cells, add a formula, save to OPFS, reload the page, verify persistence. No server process running anywhere. This is the architectural payoff — improvise running entirely in the browser.","design":"Architecture under test: main-thread wasm-client (thin client), dedicated worker hosting worker-server bundle, MessageChannel transport between them, OPFS persistence via the VFS abstraction. Test plan: (1) Visit the deployed GH Pages URL or run the shell locally. (2) Bundled demo file loads automatically via the worker on init. (3) Navigate with arrow keys — view effects dispatched locally in the thin-client wasm, no postMessage round-trip. (4) Enter edit mode, type a number, commit — command flows to worker via MessageChannel, worker updates model + persists to OPFS, projection command flows back. (5) Add a formula — same path, plus formula recompute in worker. (6) Trigger save (explicit save to user-picked path via File System Access API, or implicit autosave to OPFS). (7) Close the tab, reopen the URL, verify edits persisted. (8) Upload a different .improv file via file picker, verify it opens. Performance: cursor moves under 16ms (local, no worker hop); edit commits under 100ms (worker hop + OPFS write).","acceptance_criteria":"(1) All test plan steps pass in Chrome and Firefox.

(5) README updated with link to live demo.","notes":"INHERITS improvise-d31's AC 4 -- a bundled demo model -- which could not be satisfied there. TWO DISTINCT SUB-GAPS, both real:\n\n(a) NOTHING IN THE BROWSER LOADS A .improv AT ALL. The ws-server takes the file on its CLI; the worker needs an 'init from these bytes / this URL' entry before a bundled file has any consumer. So this is genuinely after improvise-9x6, not merely sequenced after it.\n\n(b) examples/demo.improv IS UNUSABLE AS A DEMO and the fix is not an axis flip. Customer and Date sit on the None axis, so every cell is an aggregate and nothing is editable -- correct behaviour, useless demo. Moving Date to page does NOT obviously fix it: Product x Region by Date_Month x Measure with Customer and Date fixed can still aggregate. This needs a model BUILT AND CHECKED against the 'is every visible cell a Record' question, not an axis changed and hoped for. The check is cheap now that ADR 002 exists -- a cell is settable iff its CellId is Record -- so write the assertion first and make a model that satisfies it.\nGROOMED 2026-09-20 after wave 1. Most of this milestone is now DEMONSTRABLE BY TEST rather than by hand, which is a better outcome than a manual sign-off, and the remainder is narrowed.\n\nDEMONSTRATED by harness/ (improvise-vvl3), running in CI and able to fail the build:\n * the seeded demo document drawing in the STANDALONE WORKER deployment -- no server process anywhere;\n * click-to-edit committing through the host and the host's formatted value coming back;\n * PERSISTENCE ACROSS A RELOAD at the storage layer, including that a committed delete stays deleted -- which was the one acceptance criterion no test in this repo could structurally reach;\n * every #status message the shell must write.\n\nNOT DEMONSTRATED, and one of them is a real gap in the criteria rather than in the harness:\n * 'ADD A FORMULA' -- the browser has no formula entry at all. That is the honest remaining item and it is a FEATURE, not a verification gap. It wants its own bead before this milestone can be called met as written.\n * Safari (Playwright's WebKit has no OPFS -- improvise-xf1);\n * two tabs;\n * bindings.rs and web/worker.js as CODE PATHS -- the harness drives OpfsFs directly and never instantiates the shim, so bindings.rs is now the dark corner OpfsFs used to be.\n\nAlso note improvise-plcx: web/demo.improv has no groups and one category per axis, so the harness never exercises the multi-level and group paths PR #23 added.\nVERIFICATION PASS, wave 2 WU-P, 2026-09-20 at 52507a6. Each acceptance\ncriterion walked against the DEPLOYED page, the harness and the code. Two are\nmet with evidence, one is met and was previously only asserted, and two are\nnot met — the ticket stays OPEN and the reason is (1), not paperwork.\n\n(1) ALL TEST PLAN STEPS PASS IN CHROME AND FIREFOX — NOT MET, two reasons.\n    First, test-plan step 5, \"add a formula\", has no implementation: a browser\n    can ENTER FormulaEdit and cannot commit it (improvise-fdt6, which this\n    ticket already depends on). Second, \"and Firefox\" is not true even for the\n    steps that do work. harness/playwright.config.js runs shell.spec.js on\n    CHROMIUM ONLY; Firefox and WebKit are restricted to opfs.spec.js by\n    `testMatch`, and WebKit skips that on a runtime OPFS probe. So the whole\n    shell — the page drawing the demo out of the worker, click-to-edit\n    committing — is verified on exactly one engine. That second half is NOT\n    recorded anywhere in this ticket's earlier annotation, which said \"Chrome\n    and Firefox\" was covered by the harness.\n\n(2) PAGE LOAD TO INTERACTIVE UNDER 3 SECONDS — MET, measured rather than\n    argued. Three cold loads of https://fiddlerwoaroof.github.io/improvise/\n    driven with Playwright Chromium, a freshly launched browser per run (so\n    empty HTTP cache and empty OPFS), timing `goto` until `#grid table` AND the\n    first `#grid td.editable` are both visible: 1172 ms, 278 ms, 408 ms, zero\n    page errors, `#status` reading \"in-page worker · demo.improv\" and 12 cells\n    drawn. The honest caveat: that is a fast connection with no throttling, so\n    it bounds instantiation and handshake, not \"a typical connection\". The\n    transfer it has to make is small enough that this is unlikely to be the\n    binding constraint — see (3).\n\n(3) WASM BUNDLE UNDER 3 MB COMPRESSED — MET, by an order of magnitude, and\n    measured OFF THE DEPLOYED SITE rather than off a local build. Requested\n    with `Accept-Encoding: gzip` from GitHub Pages:\n      improvise_wasm_client_bg.wasm      151,522 B gzipped\n      improvise_worker_server_bg.wasm    547,952 B gzipped\n      both .js glue files                 10,019 B\n      app.js + worker.js + style.css       7,741 B\n      index.html + demo.improv             2,161 B\n    Two wasm binaries total 699 KB gzipped; the whole site is about 719 KB.\n\n(4) SCREENCAST OR SCREENSHOT SERIES ATTACHED TO THE ISSUE — NOT MET, and not\n    meetable as written: bd has no attachments. A full-page screenshot of the\n    live site was captured during this pass and the numbers in (2) came off the\n    same run. The earlier annotation's argument stands and is the right one —\n    harness/tests/shell.spec.js proves the path in CI where a screenshot proves\n    a moment — so the useful outcome is to REWRITE this criterion, not to\n    satisfy it.\n\n(5) README UPDATED WITH LINK TO LIVE DEMO — MET. README's \"In the browser\"\n    section carries https://fiddlerwoaroof.github.io/improvise/ and describes\n    the no-server deployment. Wave 2 also corrected the same section's claim\n    that a deploy waits on \"cargo test and the wasm32 check\": it waits on the\n    browser harness too (`needs: [test, wasm, browser, pages-build]`).\n\nREMAINING CONTENT OF THIS TICKET: improvise-fdt6, plus deciding whether \"and\nFirefox\" in (1) is a requirement or a date. If it is a requirement it is a\n`testMatch` change in harness/playwright.config.js and the reason it is\nChromium-only today (routeWebSocket being slower and flakier across three\nengines) applies only to the FOUR ?ws= specs, not to the two standalone ones.\nCORRECTION TO THE NOT-DEMONSTRATED LIST, from adversarial review of PR #47.\n\nThat list says \"bindings.rs and web/worker.js as CODE PATHS\" are not\ndemonstrated, \"the harness drives OpfsFs directly and never instantiates the\nshim\". That is no longer true, and has not been since improvise-vvl3.\n\n`harness/tests/shell.spec.js`'s standalone tests load /app/index.html with no\n?ws=, which spawns the real worker: app.js -\u003e worker.js -\u003e the worker bundle's\n`start()` in bindings.rs -\u003e `OpfsFs::open().await`. Both `bindings.rs` AND\n`web/worker.js` are therefore executed under Chromium on every CI run, and the\nspec's own comment says so. Verified by running it at 2ccd21f and watching\n/app/worker.js and /app/worker-pkg/improvise_worker_server_bg.wasm fetched and\nthe grid drawn from OPFS.\n\nSo one item on that list is met rather than unmet. What genuinely remains\nunmet: Safari (improvise-xf1), two tabs, and \"add a formula\" (improvise-fdt6).\nFirefox is improvise-zkkw — a second ENGINE for the shim, which is a real gap\nand a different claim from \"never run at all\".\n\nA criterion recorded unmet when it is met is the same defect as one recorded met\nwhen it is not: both are a claim nobody rechecked.\nURL CORRECTION to the verification annotation above.\n\nThat annotation cites `https://fiddlerwoaroof.github.io/improvise/` as what was\nmeasured for criteria (2) page-load-to-interactive, (3) bundle size and (5) the\nREADME link. Those measurements were taken against the browser APP, and were\ncorrect when taken — but this same PR then moved the app, on a user ruling\n(improvise-kh8): the site root is now the LANDING PAGE and the app is at\n`https://fiddlerwoaroof.github.io/improvise/app/`.\n\nThe measurements stand — 1172/278/408 ms to an editable grid, 699 KB gzipped for\nthe two wasm binaries — and every URL that produced them now names the wrong\npage. Read every bare `…github.io/improvise/` in that annotation as\n`…github.io/improvise/app/`. Anyone re-running them against the root will be\ntiming four asciinema players instead, and would get a number that looks\nplausible and means nothing.\nGROOM 2026-09-21: this bead read READY -- every dependency closed -- while its own criterion (1) was failing. Two blockers added, both found today and neither existing when the tree was last true:\n\n - improvise-1wft: the browser's boot fails silently for five distinct causes. One of them (improvise-i0v9) is the SHIPPED DEMO showing a blank grid with a reassuring status line for 8 seconds and then blaming the browser. A demo that does that has not met 'all test plan steps pass'.\n - improvise-p7lh: the shipped demo has a page axis and the browser draws no page bar, and no column totals.\n\nCriterion (1) also says Chrome AND FIREFOX. harness/tests/shell.spec.js is CHROMIUM ONLY by deliberate configuration (engine-independent logic; routeWebSocket is slower and flakier across three), so nothing currently runs the shell on Firefox. improvise-zkkw is closed and recorded that gap; the criterion still names Firefox. Decide whether to run the shell spec on Firefox or to amend the criterion -- do not close this bead by quietly reading 'Chrome' alone.\n\nCriteria (2) load under 3s, (3) wasm under 3MB compressed, (4) screencast and (5) README link are unverified here and are cheap to measure. They are the actual remaining work on this bead.","status":"open","priority":1,"issue_type":"feature","owner":"el-github@elangley.org","created_at":"2026-04-14T07:34:38Z","created_by":"spot","updated_at":"2026-09-21T21:27:14Z","labels":["area:epic"],"dependencies":[{"issue_id":"improvise-bck","depends_on_id":"improvise-1wft","type":"blocks","created_at":"2026-09-21T21:31:53Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-bck","depends_on_id":"improvise-9x6","type":"blocks","created_at":"2026-04-14T00:40:17Z","created_by":"spot","metadata":"{}"},{"issue_id":"improvise-bck","depends_on_id":"improvise-d31","type":"blocks","created_at":"2026-04-14T00:40:16Z","created_by":"spot","metadata":"{}"},{"issue_id":"improvise-bck","depends_on_id":"improvise-djm","type":"blocks","created_at":"2026-04-14T00:40:16Z","created_by":"spot","metadata":"{}"},{"issue_id":"improvise-bck","depends_on_id":"improvise-fdt6","type":"blocks","created_at":"2026-09-20T16:21:00Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-bck","depends_on_id":"improvise-p7lh","type":"blocks","created_at":"2026-09-21T21:31:54Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-bck","depends_on_id":"improvise-tm6","type":"parent-child","created_at":"2026-09-25T01:07:37Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-bck","depends_on_id":"improvise-zkkw","type":"blocks","created_at":"2026-09-20T18:02:34Z","created_by":"wave2-p-milestones","metadata":"{}"}],"dependency_count":7,"dependent_count":0,"comment_count":0}

A classic worker fails to parse it, and that failure does reach the error listener.\n\nTHE WEBSOCKET PATH IS KEPT, worker is the default: ?ws= selects the socket, its absence spawns the worker, and THE PRESENCE OF THE PARAMETER IS THE WHOLE SELECTION MECHANISM -- a second knob (?transport=) would name the same fact twice. Kept because improvise-ws-server is the only way a TUI-hosted document is shared, and deleting the page's path to it would leave a working server nothing could reach. The cost is not 'two things to keep working': the transports differ only in WHERE STRINGS COME FROM. Handshake, on_frame, repaint, typed_cell and keydown are all above the seam, so the difference is confined to two ~15-line factories returning { send, ready }.

Every JS call confirmed against the generated .d.ts with the right arity.\n\nNOT VERIFIED, and this is the whole remaining risk: NOBODY HAS OPENED THE PAGE. No browser, no headless DOM. Every line of app.js and worker.js is read, not run -- the module-worker spawn, OPFS, ResizeObserver arithmetic, click-to-edit, keydown, the CSS. The Pages workflow has also never run.\n\nAC 4 is partly blocked: cell edit, formula entry and reload work through Commands; keyboard-driven interaction needs improvise-bpq2, and today NO KEY PRODUCES A VISIBLE CHANGE -- Host::handle answers ClientFrame::Key with an empty vec, and keys.rs resolves locally only in minibuffer modes you can only enter via an upstream key.

Same Command protocol and DOM renderer as mode 2; transport is an in-process command bus. Persistence abstracted behind a Storage trait (or the vfs crate) with PhysicalFS backing for native and OPFS backing for wasm. This makes sqlite/parquet formats a later orthogonal win — VFS handles bytes→medium, new format modules handle data→bytes.

Two more edges reach the re-key before their own steps land, and the ticket does not name either.\n\n1. **The .improv reader and writer, before cq1q.5.** After .4, the keys are slugs (`region`, `east`) and the displays are the typed names. Until .5 lands, the only file format is the old one. So:\n   - the old-format loader must already assign ids by slugify and resolve references against displays (clause 5's old arm, currently .5's scope);\n   - the writer must write displays, not keys.\n\n   If the writer writes keys, every save between .4 and .5 lowercases and strips the user's names (`Region` → `region`, `Café` → `caf`), and nothing can restore them.\n\n2. **Wire operands and projection names, before cq1q.7/.8.** After .3, the browser's panels show displays taken from the projections, and the browser composes `SetAxis { category, .. }`, `HideItem` and the rest from the same strings. After .4 the host keys by id, so between .4 and .8 every such command names a key that does not exist. That covers almost every real name, because slugify folds case. The fix is one of:\n   - `ui/reduce.rs::model_effects` resolves display→id as an interim input edge;\n   - the projections keep carrying the key alongside the display.\n\n   ViewState's name-keyed cursors, expanded_cats and view history (cq1q.7) meet the same seam.\n\nADR 007 clause 11 orders the migration the same way (re-key, then persistence, then projections, then vocabulary), so this is a gap in the step boundaries rather than in the ADR's decisions. What is needed: .4's acceptance criteria say the suite stays green, and they name these two interim edges. Or .4 is split so that each step leaves main shippable. A test for edge 1: a document with display `Region` survives save/load between .4 and .5 with its display intact.\n\nA smaller point: cq1q.3 depends on cq1q.2, but adding a display field needs neither slugify nor the allocator.

Citations are at gh/main b639266b.\n\nEight view-scoped commands in the command language build `ViewTarget::Active`, and take no view operand:\n\n- `set-axis`, `set-page`, `toggle-group`, `hide-item`, `show-item`, `set-format` (`crates/improvise-command/src/command/cmd/effect_cmds.rs:338`, `:351`, `:364`, `:377`, `:390`, `:412`)\n- `transpose` (`command/cmd/cell.rs:711`)\n- `toggle-prune-empty` (`command/cmd/grid.rs:882`)\n\nWhat each one changes therefore depends on which view the running session is on. The wire closed the same gap with improvise-lltt, where every view-scoped `ModelCommand` carries `view: String` (gotcha 29), but the command language, which is the first-class product surface for `improvise cmd`/`script`, did not. So a script cannot say \"set the axis in view B\" without first `switch-view B`, which is session UI state. Nor can any record of a view-configuration change be replayed without replaying the UI. There is also no explicit-operand command at all for `CycleAxis` (only `cycle-axis-at-cursor`/`cycle-axis-for-tile`).\n\nNot covered by improvise-31oe.2 (unknown names are silent no-ops) or improvise-31oe.3 (pipe quoting, extra arguments). Neither mentions a view operand. improvise-lltt is the wire half and is closed.\n\nFix direction: an optional view operand on each command, defaulting to the active view so interactive use is unchanged. It resolves strictly: a view the document lacks is refused, not a fallback, as wpxr ruled for `SetCell`/`ClearCell`. The spelling (a trailing argument, or a flag) has to agree with improvise-31oe.3's argument-count rules, so coordinate with it.

There is no spelling that forces text, so:\n\n- `set-cell 100 Region/East _Measure/Code` stores Number(100).\n- `set-cell \"100\" …` stores Number(100). The parser strips the double quotes before the command sees them.\n- `set-cell |100| …` stores Text(\"|100|\"): the command language does not read pipe quoting (improvise-31oe.3), so the pipes are kept literally, and the file writes `|\\|100\\||`.\n- `set-cell inf …` stores a Number (`f64::from_str` accepts `inf`, `infinity` and `nan`, case-insensitively), where a user writing the word almost certainly meant text.\n\nSo a text cell holding `100`, which `.improv` writes pipe-quoted precisely so it reads back as text (gotcha 34, `pipe_quote`), cannot be written from the command language at all.

This is broader than improvise-i0n7 (which covers only the CategoryRow shape of _Measure formula-target rows).\n\nADR 007 does not say how a formula and its target are identified in the file or the model. An implementer hits these at once:\n\n1. **No grammar for the formula line.** Clause 5's grammar block gives header_decl, item_decl and grouped_item, but no `formula_line` or formula `target` rule for answer 5's F1 (`- Profit(profit) = revenue - cost [cat]`). `formula.pest`'s `formula = { SOI ~ target ~ \"=\" ~ expr ... }` has no id tag, and today the whole line is `formula_raw`.\n2. **Whose id is in the parentheses?** Answer 5 (Q2) is *formula* id placement. Answer 19's `Profit (profit)` is described as \"the target's id\". For a `_Measure` target these coincide (clause 1: the target's handle is its FormulaId). For a target outside `_Measure`, `Model::add_formula` creates a real item. Under answer 22 (ids globally unique), that item's ItemId and the formula's FormulaId must differ. So the file must reference the target item by id somewhere, and the ADR does not say where.\n3. **Where a `_Measure` target's display lives.** Clause 2 gives `display` to Category, Item and View, but not to Formula. km71's section says \"a target change becomes a display rename of the target\", and a `_Measure` target has no item to hold that display.\n4. **Which ItemId a formula cell's CellKey carries** for a `_Measure` target, which has no item. Also `RecordCell.measure: Option\u003cString\u003e` and `CellId::Derived { target: String }` (render.rs) name the target.\n5. **WHERE / IS filter values.** formula.pest has `filter_value = { string | pipe_quoted | bare_ident }`. Is a double-quoted `\"East Coast\"` in id-form text an id or a display? Answer 3 says every reference is an id, but a quoted string has no stated meaning under ids.\n6. **Resolving typed names at the panel edge.** If a typed display name is ambiguous (answer 19), or equals some other thing's id, which wins, or is it refused?\n","status":"open","priority":2,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-24T22:49:30Z","created_by":"agent-review-210","updated_at":"2026-09-24T22:49:30Z","labels":["adversarial-review","pr-210"],"dependencies":[{"issue_id":"improvise-m56i","depends_on_id":"improvise-cq1q","type":"parent-child","created_at":"2026-09-25T01:04:54Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-m56i","depends_on_id":"improvise-sboz","type":"discovered-from","created_at":"2026-09-24T22:49:30Z","created_by":"agent-review-210","metadata":"{}"}],"comments":[{"id":"0c2ab9a3-bfb7-5273-89bb-99fc544e5a06","issue_id":"improvise-m56i","author":"agent-adr007","text":"agent-adr007 planning.

That is false for one id: `format`.\n\nIn improv.pest, `view_entry = _{ format_line | prune_line | hidden_line | collapsed_line | axis_line }` is an ordered choice, and `format_line = { \"format: \" ~ rest_of_line ~ ... }`. So the axis line for a category whose id is `format` (`format: row`, `format: page, east`) matches format_line first and is read as the view's number format. The axis assignment is lost with no error. (`prune: row` and `hidden: row` fail their own rule and backtrack to axis_line, so only `format` collides.)\n\nToday this is masked by accident: `quote::KEYWORDS` contains `FORMAT` (a formula keyword, from d00cea24), matched case-insensitively, so `format_md` writes `|format|: row`. Under ADR 007, slugify folds to lower case (answer 16(b)), so any category displayed `Format` gets the id `format`, and `id_ref` cannot quote it.\n\nThe implementation must pick one: reserve `format` from slugify (suffix it like any collision), give `id_ref` a pipe-quoted arm, or reorder or disambiguate the view-section rules.

I materialised the merge of the two heads.\n\n1. **The merge does not compile.** Git merges `client.rs` cleanly, but each side adds its own `ClientState::notify`, so the result has E0592 (duplicate definitions). The only textual conflict is in `context/test-evidence/clients.md`. A clean merge of the Rust files is exactly what makes this easy to miss.\n   - #266's version queues the sentence through `fold_outgoing` (at the tail of `in_flight`).\n   - #279's version writes `view.status_msg` directly and calls `settle_status`.\n\n2. **Keep #266's `notify`; #279 should adapt.** #279's direct write is the shape n0pb removed: a rebase erases it. #266's version already records an owner: `fold_outgoing` → `apply` → `settle_status`. The owner lives on `ClientState`, not per slice, so settling the queued entry later does not lose it.\n   - With #279's `notify` deleted, the merged tree passes the whole workspace, including #279's `a_rejection_that_arrives_in_an_open_editor_stands_beside_it`.\n\n3. **After the merge, `rebase()` must also call `settle_status()`.** #266's `rebase()` calls `replay`, `settle_mode` and `settle_editor`, but not #279's `settle_status`.

Returning to an equal editor then makes the message stand again, which contradicts #279's rule that \"an equal editor opened later is another opening\".\n   - Probe, in the merged tree:\n     1. `SetSelected(1,1)` → `ChangeMode(editing)` → `SetStatus`; the message stands.\n     2.

PR #282 introduces this; PR #277 alone (aab62a36) does not have it.\n\n`ClientState::settle_declined_editor` runs after every fold, including the fold of the client's OWN outgoing frame. The frame for an advance is `scrolled_to` (SetSelected, SetRowOffset/SetColOffset) and then the open (SetBuffer, SetOpenedEditor, ChangeMode). By the time ChangeMode(Editing) is folded, the view's offsets are the NEW ones, but the GridCache still holds the OLD window, because the host has not answered yet. `declined_at` -\u003e `cell_at` subtracts the new offsets and indexes the old cache, so it reads a different cell from the one under the cursor.\n\nA one-step scroll happens to read the cell just committed, which is editable, so it is harmless. A Down that WRAPS from the bottom row to (0, col+1) does not. It jumps the row offset back to 0, and cache row 0 is then the old window's top row.\n\nRepro (reviewer's scratch test on 942f57e5, not pushed). `_Measure` on rows [Revenue, Profit, Cost], where Profit is an explicit item AND `Profit = Revenue - Cost`.

Kit is expanded, so the client does not refuse. It composes HideItem{Region, item: \"Coast\"}, a group name, and the twin host accepts it and writes 'hidden: Region/Coast'.

So the next such relay erases the sentence, and the user loses the one notice that their edit was not applied. `last_rejection` survives, but the sentence is gone.\n\nReproduced through the page's own entry point, `Client::fold_frame`:\n1.

The fold keeps running while the editor is open, so another client's write to the same record bumps that counter, and the commit claims the fresh one and is accepted.\n\nReproduced with a scratch test (not committed): a real Host, two sessions, North/Revenue = 1200, window 2x1.\n- Client A presses `i Backspace 4 2` (buffer \"12042\").\n- Client B writes North = 999 through the host.

If the record has no stored cells, it falls back to record_in_layout, which reads self.layout, and that is the HOST's active view. Since improvise-jytm, the host's view is not the client's. So a client's write to an EMPTY cell succeeds or fails depending on which view the host is on.\n\nWITNESS (a scratch test in ui/host.rs, run and then discarded). It uses host() (Region x _Measure, no stored cells) and adds a view \"Other\" that hides Region/South. The client connects and its Snapshot names view \"Default\", where South's empty cell is drawn.\n- Control: with the host on Default, the client's `host.model(SetCell(addressed(\"South\"), 3))` is Accepted.\n- Same setup with the host switched to Other (switch_to_view plus rebuild_layout): the identical write is Rejected(RecordGone). The client is still on Default and can see the cell.\n\nThis is the record-shaped twin of improvise-obtu, which covers aggregates only. gotcha 44 says a RecordHash is \"document-scoped\" and \"works from any view\". That holds only for records with stored cells. An empty record is layout-scoped, through the host's layout.\n\nLikely fix shape: resolve against a layout derived for the ASKING session's view, as obtu proposes for aggregates. Or resolve an empty record from the document's categories, independent of any layout. The second must still refuse a group, formula or aggregate cell (unwritable, ciw8/xur5).\n\nNOTE for tests: improvise-3til's test (PR #267) deliberately has no follow-up write.

This bug is PRE-EXISTING. I reproduced it against gh/main 202e7eac's protocol and command sources, with the same numbers. It is the same class as improvise-mdfc, but reached through a door that #227 does not touch.\n\nmdfc made the ADVANCE await whenever any awaited frame is in flight. The other door into the cell editor is `i`/`a`, resolved by edit_or_drill, which calls opened_on(cell.edit_text). That door still seeds from the client's cache with no in-flight check. The same holds for any other opener that reads seed_at/edit_seed while a write is unanswered, for example a click-edit, which is the improvise-ugj4 path; I did not probe that one.\n\nProbe: a real Host and ClientState. The fixture is one measure column. The cursor is on North = 1, which is the rightmost column.

It is a regression that #227 introduces. It is the 3tt4/3uzg harm again, reached by pipelining.\n\nresolve::advanced reopens the editor as OpenedEditor::awaiting() only when THIS commit writes. A commit that writes nothing (an untouched Enter or Tab) still seeds at once from the cache: `false =\u003e opened_on(seed_at(state, nr, nc), edit_mode)`. protocol.md §3 justifies this with \"Nothing changed, so the cache is current\". That is false while an EARLIER write is still unanswered: the cache still predates it. settle_awaited_seed never repairs the seed, because the editor it opened is not awaiting.\n\nReproduced in two ways:\n1. Real Chromium over the worker, harness fixture tall.improv, R01/Cost = 50 (the rightmost column), keys pressed back to back: i 9 Tab Tab 5 Enter. The browser stores 505 in 5 runs out of 5.

That is false under `prune_empty`. A commit that empties the last value in a row (or a column) prunes that row.

It does not track a multi-line quoted string or a heredoc body, and it does not apply YAML's folded (\u003e) or plain-multiline scalar rules. So a bare `./scripts/checkers.sh` on a line of its own reads as a bare invocation, which checkers.sh --would-run answers as EVERY suite. A suite that no step runs then passes, silently. This is the same fail-open class as improvise-maax item 1 (a bare mention reads as every suite runs), reached through a different mechanism.\n\nDemonstrated against the real ci.yml, with a planted suite zz-new (scripts/zz-new plus zz-new-test.sh) that no step runs. The gate exits 1 on the plant alone. It exits 0 after either of these edits:\n1. A step-summary heredoc (a realistic step):\n   run: |\n     cat \u003e\u003e \"$GITHUB_STEP_SUMMARY\" \u003c\u003c'EOF'\n     To reproduce locally, run\n     ./scripts/checkers.sh\n     from the repository root.\n     EOF\n2. Folding the kb job's last step as `run: \u003e` with `./scripts/checkers.sh` on one line and `pr-watch release-preflight pr-reviews fmt-workspaces` on the next. yq confirms that the YAML value is `./scripts/checkers.sh pr-watch release-preflight pr-reviews fmt-workspaces`, so only four suites run.\n\nThe same result comes from a multi-line double-quoted string that contains the bare line, and from a plain multi-line scalar (`run: ./scripts/checkers.sh` followed by an indented `kb`). A third mechanism gives the same result: `\"--command\" in words[k:]` matches any command, so `echo use --command ./scripts/checkers.sh` also reads as every suite.\n\nThe claim in context/code/tooling.md, \"A line shlex cannot parse contributes nothing, which fails closed\", is true of that one line only. The following lines are then misread. The same paragraph also says \"a CI step that spells it anywhere is a usage error rather than a green step that ran nothing\". That is false for the first position: `checkers.sh --would-run kb` in a step exits 0 and runs nothing. The gate still catches it, because asking `--would-run --would-run kb` is exit 4, so nothing is counted. But the step itself is green.\n\nFix direction (fail closed): tokenise the whole script rather than each line, so quotes span lines. Contribute nothing from a heredoc body, or refuse a script that contains `\u003c\u003c`. Fold `\u003e` and plain-multiline values the way YAML does.

{"_type":"issue","id":"improvise-jpba","title":"A client refusal replays from a settled slice that never folded the host's relays: after a reframe, the next refused frame splits the client cursor from its mirror","description":"Found while adversarially reviewing PR #230 (improvise-wdmp) at head 93c455db. It is pre-existing: reproduced at gh/main 194d8f52. It is not caused by #230.\n\n`ClientState::refused` rolls back by `replay()`: `view = settled.clone()`, then re-folding every in-flight frame. But `settled` only ever absorbs the client's OWN frames, in `accepted()`. A command the host RELAYS to the asker (`ResetCursor` from `adopt_cursor_epoch`, the per-client `SwitchView` from `adopt_deleted_views`, and now #230's echoed placements) is folded into `view` only. The next refusal therefore rewinds the client past every relay it has heard, while the host's mirror keeps them.\n\nReproduction, as a host test in ui/host.rs with a real `Host` and a real `ClientState` (it folds every frame addressed to the asker):\n1. The asker sends `[SetSelected(1,0)]`. It is accepted, and client, settled and mirror are all at (1,0).\n2. The asker sends `[ChangeMode(Normal), AddCategory(\"Product\")]`. The mirror is reset to (0,0) and `ResetCursor` is relayed, so the client view is (0,0). `settled` stays at (1,0).\n3. The asker sends an `AddCategory` whose basis was taken before step 2. It is refused (stale layout), and `refused()` calls `replay()`.\nResult: the client is at (1,0) and its mirror at (0,0). This is the client/mirror cursor split improvise-wdmp closes, reopened by any later refusal.

Debug renders Model::formula_cache, a HashMap\u003cCellKey, CellValue\u003e the serde form skipped (#[serde(skip)]). recompute_formulas clears and refills it, and the refilled map iterates in a different order.\n\nDemonstrated: a temporary test built a workbook with 8 regions x Revenue/Cost and two formulas (Profit, Margin), then applied RebuildLayout, a correct ViewOnly effect that calls recompute_formulas. The Debug fingerprint differed before/after in 90/200 and 82/200 runs.

The formula works, but it sits in the last position rather than Total's.\n\nCause: `replace_formula` copies `add_formula`'s \"a non-_Measure target becomes a real item\" (`cat.add_item(\u0026formula.target)`) and never removes the old target's item. A `_Measure` target is implied by `measure_item_names()`, so it follows the formula's slot. That is why km71's in-place tests, which are all `_Measure`, cannot see this.\n\nRelated, and NOT new to km71 (the same holds for `remove_formula` / `d`):\n- `Model::remove_formula` also leaves a non-`_Measure` target's item behind.\n- A `_Measure` rename or delete leaves stored cells under `_Measure=\u003cold\u003e` in the DataStore. They are invisible, because no item names them any more, and they persist in `## Data`.\n- It also leaves a stale `measure_agg` entry and stale hidden/collapsed/page-selection entries.\nThe formula shadowed those cells, so nothing the user could see is lost. `context/code/core.md` §18 names measure_agg and hidden. It does not name the stored cells.\n\nOptions: (a) the rename moves the old target's item: rename it in place when nothing else stores data under it, otherwise refuse or keep it; (b) refuse a rename for non-`_Measure` targets until improvise-sboz gives formulas stable identities; (c) document it. The acceptance test should use a Region-targeted formula at a NONZERO position of at least three items, and assert both the item order and that the old item is gone.\n","status":"closed","priority":2,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-23T14:52:53Z","created_by":"agent-review-214","updated_at":"2026-09-23T16:00:12Z","closed_at":"2026-09-23T16:00:12Z","close_reason":"Fixed in PR #214 (formula editing, user-requested), merged after adversarial review (77f059c, then the kb1d delta at f3fb83e).

Two places where the ADR's projection and `ViewState` clauses do not match the code at 4b880846.\n\n1. **`CategoryRow.items` cannot become `(ItemId, String)` for `_Measure`.** `project.rs::category_rows` fills `items` from `Model::effective_item_names`, which for `_Measure` is the explicit items plus the formula targets (gotcha 7). Clause 1 says a formula target in `_Measure` \"has no item of its own to carry\" an id. So the clause 6 shape has no id to put in those rows. The category panel does act on them today: `resolve.rs::delete_at_cat_cursor` composes `RemoveItem { category, item }` for any item row, formula targets included, and fz77's rename will too. The ADR must say what a formula-target row carries (its `FormulaId`? nothing?) and what remove or rename means on it.\n\n2. **`ViewState` holds more name-keyed state than the two fields clause 6 names.** Clause 6 warns only about `active_view` and `cursors` for a future view rename. But:\n   - `ViewState::expanded_cats: HashSet\u003cString\u003e` is keyed by **category** name. fz77's category rename, which this ADR unblocks now rather than later, collapses the renamed category's panel node for every client, with nothing in the stream to correct it.\n   - `view_back_stack`/`view_forward_stack` hold `ViewFrame { view_name }`, which a view rename orphans exactly as it orphans `cursors`.\n\n   These are per-client state the host cannot rewrite.

The ADR's wire clauses (6 and 7) leave four things unsaid, each checked against the code at 4b880846.\n\n1. **An id removed earlier in the same frame.** `CheckedBatch::against` answers every command against the pre-frame `App`. So `[RemoveFormula(3), EditFormula(3)]` passes the check, since id 3 resolves before anything runs. The per-mutation structural re-check that catches this for records is `reduce.rs::broken_chain` (`Rejection::ChainBroken`), and it only walks `records_named`. The ADR adds `Rejection::Gone` to the pre-frame check and says nothing about the in-frame case. So whether the frame is refused loudly (via `MutationRefused`) or half-applied silently depends on how each new effect behaves on a missing id. The ADR should say that `broken_chain` gains an id arm, and that an exhaustive `ids_named(cmd)` (the analogue of `records_named`) is the server's decision about which ids a command names.\n\n2. **`Rejection` is `Copy`, and `Gone(Named)` breaks it under the Q1 recommendation.** `basis.rs` derives `Copy` on `Rejection`, and relies on it: the `SaveFailed` doc says it carries no message *because* `Rejection` is `Copy`. `Rejection::all(sample: RecordHash)` walks the variants with a `RecordHash` sample only. Q1 recommends that ids be \"a small string internally\", which makes `Named`, and so `Rejection`, non-`Copy`. Q1 does not list that cost. Nor does it define \"max id seen + 1\" (clause 3) when ids can be words.\n\n3. **\"Create by name\" operations also address a parent.** `AddItem { category }`, `AddItemInGroup { category, group }` and `AddFormula { target_category }` create one thing and address an existing one by name. Clause 6 files them under \"keep names\", while its own rule says a migrated variant takes ids for \"all of its addressing operands\". An `AddItem` racing a category remove-and-re-add lands on the namesake, which is the hazard the ADR exists to close. The fdk1 variant does the mixed form (category by id, item by name), so the ADR already accepts it. It should say which rule governs the create variants.\n\n4. **Create-then-address in one frame already ships.** `resolve.rs` \"create-and-switch-view\" sends `[CreateView(name), SwitchView(name)]`. Clause 7's \"no id exemption to write, and none should be\" holds only while `SwitchView` stays by name. Clause 6 requires `ViewState` keys to move to `ViewId` before any view rename. When they do, this frame cannot be composed, because the client cannot know the new view's id. \"The host assigns every id\" is therefore a decision, not a consequence. The alternative (a client proposes an id on create, as Q1's word ids would allow) is not presented.\n","status":"closed","priority":2,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-23T06:36:11Z","created_by":"agent-review-210","updated_at":"2026-09-25T06:35:45Z","closed_at":"2026-09-25T06:35:45Z","close_reason":"Answered by accepted ADR 007 (revision 8); verified by the PR #318 review (issuecomment-5827855684)","dependencies":[{"issue_id":"improvise-gkyo","depends_on_id":"improvise-cq1q","type":"parent-child","created_at":"2026-09-25T01:04:51Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-gkyo","depends_on_id":"improvise-sboz","type":"discovered-from","created_at":"2026-09-23T06:36:11Z","created_by":"agent-review-210","metadata":"{}"}],"comments":[{"id":"9b3b442b-340b-55a2-b820-fe7f8e6b80f2","issue_id":"improvise-gkyo","author":"agent-adr007","text":"agent-adr007 planning: revision 8 answers all four items.

Measured on the M4 Max:\n- that rival plus gotcha 18: the guard fires 200 of 200;\n- clean: the law passes 200 of 200.\n\nRelated, and not a defect in #208: the drill is the law's **only** witness for gotcha 18 in the demo. With `drill_snapshot` switched to `iter_cells().filter(matches_partial)` and gotcha 18 injected, the law passes 200 of 200. That pass is correct, since no command then follows hash order. But no other command's compared text is sensitive to `matching_cells` order in this fixture.\n","status":"closed","priority":2,"issue_type":"bug","assignee":"agent-hzjo2","owner":"el-github@elangley.org","created_at":"2026-09-23T06:23:24Z","created_by":"agent-review-208","updated_at":"2026-09-23T14:56:22Z","started_at":"2026-09-23T06:25:44Z","closed_at":"2026-09-23T14:56:22Z","close_reason":"Fixed in PR #208, merged as bf2de49.

Two of #205's stale-seed guards have no test that can fail.\n\n(1) EnterMode's SetOpenedEditor(None) in cmd/mode.rs, pushed when entering an editing mode. Deleting it leaves the whole workspace green (1829 passed, 0 failed).\n(2) The same line in resolve.rs::entered(), the browser twin. Deleting it also leaves 1829 passed, 0 failed.\n\nGuard (1) is reachable. A scratch test (not committed) does the following: grid_holding(Text(\"007\")), cursor (1,1). Press i, then Esc; opened_editor keeps seed \"007\" in Normal mode, since nothing clears it on exit. Move to (0,1), which holds Number(2.0). Type `:enter-mode editing`, Enter, then type 007 and press Enter. At 5df8ed2c this stores Number(7.0), which is correct. With guard (1) deleted it stays Number(2.0): a typed value is swallowed by an escaped editor's seed. The test passes at 5df8ed2c and at gh/main, and fails only under the injection, so it discriminates.\n\nRelated gap: a trimmed comparison in untouched() (seed.trim() == text.trim()) also passes the whole workspace. A text cell ' x' edited to 'x' would then write nothing. No test separates exact from trimmed equality.\n\nFix: add the scratch test as a TUI regression, plus a resolve.rs twin driving `entered()`, plus one untouched() case whose seed and buffer differ only by whitespace.

So an editor the user deliberately edited BACK to its seed writes nothing, and a concurrent write that landed while it was open wins silently.\n\nCONFIRMED with a scratch test in crates/improvise-command/src/command/cmd/commit.rs (not committed): grid_holding(Number(7.0)), cursor (1,1) = West/Revenue. Press i (seed \"7\"). Apply effect::SetCell(West/Revenue, 5.0), standing in for another client's write. Press Backspace, then 7, then Enter. At 5df8ed2c the cell stays Number(5.0), and the user who typed 7 is told nothing. At gh/main 98d10ca5 the same test stores Number(7.0). So #205 introduces this. The browser keyboard path (resolve::written) and the mouse path (typed_cell_frame) behave the same way by construction, because they share untouched().\n\nThis is the other side of #205's own an_untouched_edit_does_not_overwrite_a_write_made_while_it_was_open, which is right for a truly untouched editor. A content comparison cannot tell 'never touched' from 'touched and put back'.\n\nIt composes badly with improvise-0j0f / PR #188. Once the basis is claimed at open, a touched write over a concurrent change should come back Rejected(RecordMoved), which is loud. #205 swallows it before it is composed, so the refusal the user would have seen never happens. The TUI host has no basis check, so there the outcome flips from 'my 7 wins' to 'their 5 wins, silently'.\n\nOptions (a decision is needed):\n(a) Keep a touched flag on OpenedEditor. Any append-char or pop-char into the edit buffer sets it, and untouched() requires !touched. Both #205 tests still pass, and so does this one.\n(b) Accept content semantics and document them.\nNote: (a) lives in ViewState, so the browser's append/pop resolvers and reduce_view must set the flag too.

Category.id and Item.id are usize values assigned on add, never keyed on and never persisted. Formula has no id at all and is effectively identified by (target, target_category).

Also how a client learns the ids (projection: CategoryTreeCache, FormulaCache).\n(4) How this interacts with ADR 002's RecordHash / CellId surrogates, and the basis check (ADR 001), e.g. an edit naming a formula id that no longer exists is RecordGone-like.\n(5) The migration path.

In `RecordRewrite::of`, change `(false, true) =\u003e vec![(None, row.coords.clone())]` to `Vec::new()`. Renaming a row seeded by `o` / add-record-row then leaves `CellKey([])` behind, so the row loses its coordinates. No test in the workspace fails. A handle_key fuzz trace does catch it. This gap predates #204: the same branch lived in `rename_record_coordinate` and the test set is unchanged.\n2. Sparse drill row. In the second loop of `of` (measures the row has no cell for), change `renamed(\u0026row.cell_key(measure))` to `row.cell_key(measure)`.

It relaxes `a_creating_column_is_named_rather_than_left_as_no_cell` from \"exactly one None on row 0\" to \"all Some on row 0\". It adds `a_coordinate_cell_is_named_rather_than_left_as_no_cell`, which pins the exact kind at ONE cell, (1, region). The whole-grid enumeration in that test then asserts only that no cell is `None`.\n\nThat enumeration answers \"is every cell something\", not \"is every cell the right thing\". The dangerous mis-projection is a coordinate projected as `CellId::Record`: `render.rs::editable` then offers it, and a typed value becomes a `SetCell` with `measure: Some(\"Region\")`. The enumeration cannot see that, and after the PR no other test sees it off row 1.\n\nCONFIRMED by injection in `cell_id` (ui/project.rs), at 6b3dd8c:\n    RecordCol::Category(c) if row == 0 =\u003e Some(c.clone()),   // falls through to CellId::Record\nEvery test in `cargo test --workspace --no-fail-fast` passed, including all 26 in ui::project::cell_identity.

So any document whose active view is not \"Default\" hands every newly connected client a back-stack frame `{view_name: \"Default\", mode: Normal}` that the client never visited. `Sessions::rebase` goes through `reseed` -\u003e `fresh_view`, so a document swap does the same. The doc comment says the slice is \"empty\", so the intent is clear.\n\nCONFIRMED with a probe test in ui/project.rs tests (not committed): `app_with_two_views()`, connect, then `install_workbook(other_document())` with \"Default\" deleted, then `rebase`. The snapshot's `view_back_stack` is `[ViewFrame { view_name: \"Default\", mode: Normal }]`. That frame names a view the incoming document does not have.\n\nConsequences:\n- If the document has a view named \"Default\" (every `Workbook::new` does) but opens elsewhere, `\u003c` in the browser moves the client to \"Default\", which it never visited. That is improvise-lrrx's symptom on the client side.\n- If it has no \"Default\", the client and its server mirror both step onto a dead name (`reduce_view::stepped` does not check). `resolve_view` falls back to the default, so `\u003c` visibly does nothing and pushes a forward frame.\n- The TUI host does not have this. `App::with_storage` sets `active_view` directly, so host and client histories differ from the first frame.\n- #193's new command.md paragraph says the client's stacks \"cannot hold a dead name: ForgetView purges them, and a load arrives as a fresh Snapshot\". This is the counterexample. That claim is the stated reason `reduce_view::stepped` may stay unchecked while `effect::stepped_to` refuses a dead frame.\n\nRepair shape: build fresh_view with `ViewState { active_view: workbook.active_view.clone(), ..ViewState::default() }`, as App::with_storage does. Do not fold a SwitchView. Test: connect and rebase against a document whose active view is NOT \"Default\" and that HAS a \"Default\" view. Assert the snapshot's back stack is empty.

Over 60 failing runs, exactly one (command, args) pair ever diverged: `drill-into-cell [\"Product/Latte\", \"Quarter/Q2\"]`. That drill is one record with two values, so each other instance agrees with probability 1/2, and (1/2)^3 is 12.5%. `fit-measure` never diverged, although the evidence entry says the injection is \"reached through `drill-into-cell` and `fit-measure`'s record order\".

Many effects are unit structs that do their work in `apply`: `ApplyAndClearDrill`, `SortData`, `CleanEmptyRecords`, `Save`, `RebuildLayout`, `AcceptWizardModel`. Hash-order nondeterminism inside an `apply` is therefore invisible to the law, and improvise-uo2p is a live P1 instance of it. `context/code/command.md` says the law guards \"the one kind of nondeterminism this repo has actually shipped\".

Measured through `Host::handle`: with views Default/Scratch/Other, the frame `[DeleteView(\"Scratch\"), DeleteView(\"Scratch\")]` answers `Accepted`, and a single `DeleteView(\"Ghost\")` is also `Accepted`. `on_view`'s own premise is that \"a view the document no longer has is a failure to report\", and it applies that to nine effects but not to DeleteView.\n\n2. **AddFormula into a category the document does not have.** For a non-`_Measure` target, `effect::AddFormula` runs `let _ = app.model_state.workbook.add_item(\u0026formula.target_category, \u0026formula.target)` and then `add_formula` anyway. Measured: `[RemoveCategory(\"Region\"), AddFormula { raw: \"Total = 1\", target_category: \"Region\" }]` answers `Accepted`, and the document now holds a formula `Total [Region]` for a category that does not exist. It persists: `format_md` writes `- Total = 1 [Region]` and `parse_md` reloads it with no Region category. A single `AddFormula { target_category: \"Ghost\" }` is also Accepted. PR #181 converted AddFormula's parse-error arm but missed this `let _`.\n\nFix shape: DeleteView refuses when the named view is absent. AddFormula refuses when `add_item` errs, before `add_formula` runs.

It must be enabled for EVERY build that parses a frame.

The premise does not hold here, because the model already evaluates a formula over aggregated inputs for Axis::None. The comparison to pivot tables is also doubtful: calculated fields in a spreadsheet pivot table evaluate the formula over the summed inputs. A collapsed group is conceptually a partial aggregation, just like a None axis, yet the two now give different answers for one formula.\n\nNote that the totals strip already sums a ratio column (1.50 here). That is pre-existing, and it is why the fold \"agrees with the total\". Agreement with that total therefore does not show the fold is correct.\n\nPossible fix: for a formula target at a group key, evaluate the formula with its refs resolved through `evaluate_aggregated` at the group key, since refs to raw measures already fold once over the group's records.

On a collapsed group's row (key `Month=Q1`), `DrillIntoCell` opens a `_Drill` view with **0 rows** (`drill_snapshot` matches no record, because no record carries the group name). That is exactly the empty drill that `EditOrDrill`'s refusal and `context/code/core.md` §14 say must not happen. The drill puts `Month` on `Filter` with the selection `Q1`, and `o` (`add-record-row`) then builds its key from `filtering_cats()` and writes `SetCell({Month=Q1, _Measure=Revenue}, 0)`. That is a record at a coordinate which is not an item, which is the write §14's settability section exists to prevent.\n\nThe result persists. `format_md` writes `Month=Q1, _Measure=Revenue = 0` into `## Data`, and it round-trips through `parse_md`.

Pre-existing, not introduced by #171; #171 NARROWS it.\n\n`improvise cmd 'move-selection 2 0 . commit-cell-edit editing 9 Region/South'` on a 3-row document (cursor ends on the last row) writes South=9, SAVES the document, prints nothing to stderr, and exits 1. Same for `add-category Foo . commit-cell-edit editing 5 Foo/x` on an empty document.\n\nCause: CommitAndAdvance's advance is EnterAdvance, which returns AbortChain when the cursor is already bottom-right (navigation.rs, \"the advance premise no longer holds\"). The CLI maps `last_batch_aborted()` to exit 1 (context/code/cli.md section 3). But the abort here is not a refusal: the write already landed, and the document is saved because `changed` is true.\n\nMeasured with real binaries:\n- pre-#151 (f7573bf): EVERY scripted commit-cell-edit exited 1 with the write saved, because the pure arm built CursorState::default() (row_count 0), so the advance always aborted.\n- #171 head: exits 0 when the cursor is not bottom-right, 1 when it is. The write lands and is saved in both cases.\n\nWhy it matters: a caller that trusts the exit code believes the document was not written, retries or rolls back, and has nothing on stderr to explain it. It is the mirror image of improvise-udt2 (a refusal that exits 0): here a success exits 1.\n\nLikely fix direction: an advance that has nowhere to go is not an abort of the user's intent in a headless run; either EnterAdvance clamps instead of aborting when it is the tail of a commit, or the CLI distinguishes \"a chain stopped after its mutation landed\" from a refusal.

Every HashMap it reached was the same instance, iterated in the same order both times, so it could only restate that a pure function is a function. Build two contexts INDEPENDENTLY from equal data (two Apps loaded from the same document) and each HashMap/HashSet gets its own RandomState. A command whose effects depend on hash iteration order then gives DIFFERENT effects, and the law fails.\n\nThat's the one kind of nondeterminism this repo has actually shipped: gotcha 18. The drill snapshot froze records in HashSet order, so the same drill in two processes addressed different records and pending edits were misdirected. And import::analyzer built distinct values through a HashSet, so the same CSV imported twice gave two different .improv files.\n\nNAMING: the old test was called an \"involution\" law but tested determinism. Involution (z twice returns to the start) needs the effects applied in between, and is improvise-6qet's business. Keep the two properties separate and named correctly.\n\nSHAPE: a property over EVERY command in the registry, not just toggle-group. For each registered command that parses from a fixture context: build the context twice from the same document, execute, and compare the effect lists by their Debug text. Commands that legitimately depend on something outside the context (time, rng) must be listed with a reason, and that list must be checked in both directions, as vocabulary_is_composed does, so it can't go stale. Beware improvise-c7mu's lesson: Debug text is also a source-text proxy.\n\nINJECT THE RIVAL: make one command iterate a HashMap from the context, e.g. ViewState::cursors or a buffers map, and emit in that order. The law must fail, and must fail ONLY for two distinct instances, not for a single reused one. That second half is what proves the distinct-instance construction is load-bearing.","status":"closed","priority":2,"issue_type":"task","assignee":"agent-registry","owner":"el-github@elangley.org","created_at":"2026-09-23T03:51:25Z","created_by":"Edward Langley","updated_at":"2026-09-23T05:52:25Z","started_at":"2026-09-23T04:12:56Z","closed_at":"2026-09-23T05:52:25Z","close_reason":"Fixed in PR #187, merged after adversarial review (content at fc0b13c, fixture delta at 0825f99; later changes were an evidence-only merge and doc corrections).

Fixture: Month with Q1={Jan,Feb}, Q2={Apr,May} on Row, Type on Column,\ncursor at data row 0. Pressing `z` (toggle-group-under-cursor) three times:\n\n  1. names Q1, collapses it\n  2. names Q2, collapses it     \u003c- NOT the group just collapsed\n  3. returns no effects at all  \u003c- row_count() is 0\n\nMechanism. expand_category skips every item of a collapsed group, so the group\ncontributes zero AxisEntry::DataItem. ToggleGroupAtCursor resolves through\nGridLayout::row_group_for(ctx.selected.0), which is indexed by DATA row and walks\nback to the nearest preceding GroupHeader. A collapsed group therefore has no data\nrow from which its own header is the nearest preceding one -- so the cursor can\nname it only while it is expanded.\n\nTwo consequences, and the second is the one a user hits:\n\n - Pressing `z` twice collapses two groups rather than restoring one. The cursor\n   did not move; the grid moved under it.\n - A collapsed group can be re-expanded only by `:toggle-group`, which names the\n   group in text. From the grid there is no way back.\n\nThis is the third bead in a family about exactly that way back -- improvise-lhi4\n(prune_empty dropped the header) and improvise-0o6x (a leading header was never\ndrawn) both fixed the header's VISIBILITY. AxisEntry's doc comment says a\nGroupHeader is always visible \"so its label and collapse state show\". Both of\nthose are now true and neither makes the header ADDRESSABLE, which is the half\nleft over.\n\nNot fixed under ub4o, which is a test bead: the three tests landed there pin the\nbehaviour above as it stands (a_second_toggle_at_the_same_cursor_names_the_next_\ngroup_not_the_collapsed_one, a_fully_collapsed_row_axis_leaves_the_command_\nnothing_to_address), so whichever answer is chosen here must edit them, which is\nthe point -- they are where the decision will be visible.\n\nOPTIONS, none obviously right:\n\n (a) Let the cursor address a header. That means a cursor position that is not a\n     data row, which row_group_for's whole signature (data_row -\u003e visual) is built\n     to avoid, and which every other cursor-addressed command would then have to\n     answer for. Expensive and wide.\n (b) Make ToggleGroupAtCursor remember: if the view has a collapsed group whose\n     header is the nearest preceding one in the VISUAL entry stream at the\n     cursor's visual position, expand that instead. Keeps the data-row cursor and\n     reads the entry stream, which is how lhi4 was resolved -- from the entries,\n     with no \u0026View.\n (c) A separate expand-all / cycle-collapse binding, leaving `z` alone.\n (d) Decide it is acceptable because `:toggle-group` exists, and record that here\n     plus in the gotcha, so the next person stops re-finding it. The family of\n     three beads is evidence somebody keeps re-finding it.\n\nWhichever is chosen, the guard must inject a rival that collapses a neighbour:\n\"some group is named\" is satisfied by the current behaviour.","notes":"USER RULING 2026-09-23, and it reframes the bug. \"When collapsing a group, I'd generally expect the cursor to move to whichever place the group collapsed into. In some cases, the right thing to do might be to attach an argument to the command that is used to invalidate later commands.\"\n\nSo this is NOT \"the header is not addressable\". It is \"THE CURSOR DID NOT FOLLOW THE CONTENT IT WAS ON\". The four options above are all answers to the wrong question, and the chosen shape is a FIFTH that none of them listed.\n\nDECIDED (user, from a presented fork): A COLLAPSED GROUP CONTRIBUTES ONE DATA ROW, WHOSE CELL IS AN AGGREGATE OVER THE GROUP.\n\nThe change is one statement. layout.rs:755 today reads:\n\n    // Skip the data item if its group is collapsed.\n    if item_group.is_some_and(|g| view.is_group_collapsed(cat_name, g)) { continue; }\n\nA collapsed group emits its GroupHeader and then skips EVERY item, contributing zero AxisEntry::DataItem -- that `continue` is the whole mechanism of this bug. Instead it should emit ONE DataItem for the group.\n\nWHY THIS SHAPE RATHER THAN THE OTHERS. It dissolves the problem instead of working around it:\n\n- The cursor lands on the collapsed group BY ARITHMETIC, with no special case. Fixture Q1={Jan,Feb}, Q2={Apr,May}, cursor at data row 0 (Jan). Collapse Q1: data rows become [Q1, Apr, May], so data row 0 IS Q1 -- exactly \"the place the group collapsed into\". Pressing z again re-expands it, so z is an involution again without anything being taught about involution.\n- NOTHING about ViewCursor, row_group_for or any cursor-addressed command changes. The alternative that literally delivered the ruling (a cursor that names a visual entry) would have changed row_group_for's signature and forced every cursor-addressed command to define what it does on a header row.\n- It is what a pivot table MEANS by a collapsed group: the group's totals in one row. Collapsing currently hides the rows and shows nothing in their place, which is the part that reads as broken.\n- Settability is already answered. ADR 002 puts CellId on the projected cell and grid_of decides it, so the row comes back as CellId::Aggregate and is non-editable in BOTH front ends with no second derivation. Do NOT re-derive editability from \"is this a group row\".\n\nTHE ORDERING CONSTRAINT THAT WILL DECIDE THE IMPLEMENTATION, and it is easy to miss. ToggleGroup is EffectKind::Model(LayoutGeometry) (verified, effect.rs:444). Gotcha 24: since improvise-ni6k the cursor is invalidated by OBSERVING the grid's frame, and apply_effects diffs the frame after every model effect INSIDE the loop. So a collapse RESETS the cursor unless the batch places it afterwards. The placement must therefore come AFTER the ToggleGroup effect in the emitted vec -- the same shape as improvise-o9uq, where \"the order is the entire fix\" and the injected rival was the SWAP rather than the omission. A test that only checks the cursor ends up right must be shown to fail with the two effects reversed.\n\nPART 2 OF THE RULING, FOLDED IN HERE rather than filed as a general mechanism (user's choice): ToggleGroup may carry the group it acted on, so a later command in the same batch can be invalidated by it. State honestly what that does and does not buy. A Binding::Sequence flattens into ONE effect vec (gotcha 21), so `z z` bound as a sequence composes both toggles against the SAME pre-batch context -- that case the argument would fix. TWO SEPARATE KEYPRESSES are a different batch each and were never affected. AND UNDER THE CHOSEN DESIGN THE SAME-BATCH CASE MAY ALSO STOP MATTERING, because the second toggle resolves against a grid where the collapsed group is an addressable row. So: implement the aggregate row FIRST, then check whether the invalidation argument still buys anything. If it does not, say so here and do not add it -- a mechanism with no reachable case is the guard-one-level-away shape this repo keeps paying for.\n\nWHAT ELSE MOVES, since row_count() grows by one per collapsed group:\n- CSV export. persistence/export.rs::render_csv builds with with_frozen_records, NOT new (improvise-iot6, gotcha 1) -- a collapsed group will now appear as a row in exports. Decide whether that is wanted and say so; it is arguably correct and is certainly a behaviour change with round-trip tests to update.\n- Column totals, the browser grid and the viewport arithmetic all read the same GridLayout, so they follow for free -- that is the argument for making the change THERE rather than in a renderer.\n- The three tests PR #156 landed pin the CURRENT behaviour (a_second_toggle_at_the_same_cursor_names_the_next_group_not_the_collapsed_one, a_fully_collapsed_row_axis_leaves_the_command_nothing_to_address). They MUST be edited -- that is deliberate, they are where this decision becomes visible.\n- collapsed_group_has_header_but_no_data_items in layout.rs asserts the premise being changed and must be inverted, not deleted.\n\nGUARD. The rival to inject is a collapse that names a NEIGHBOUR: \"some group is named\" is satisfied by the current broken behaviour. Assert the cursor's position after a collapse of a group that is NOT first on the axis, because a group at data row 0 is right by accident under both the old and new behaviour -- the same trap as a fixture whose expected count is 1.\nIMPLEMENTED (agent-collapse3, branch fix/6qet-collapse-row).

But I should be able to\nreproduce any state of the whole system by spinning up a fresh copy of an\napplication and replaying a recorded sequence of commands.\"\n\nTWO CLAUSES, and the second is much stronger than the first. \"Everything is a\ncommand\" is a discipline. \"Replay reproduces any state\" is a TESTABLE PROPERTY,\nand it is the one that makes the discipline enforceable rather than aspirational.\n\nWHAT THE TREE ALREADY GIVES US, measured:\n  - The Cmd/Effect pipeline IS the Emacs shape: a named command in a registry,\n    resolved against a read-only CmdContext, returning effects that are the only\n    mutation site. Nothing about that needs inventing.\n  - `improvise script \u003cfile\u003e` ALREADY REPLAYS a command sequence into a fresh\n    process (src/main.rs::run_headless_script), and PR #131 made it and\n    `improvise cmd` one function so they cannot diverge. So half the machinery\n    exists and is shipped.\n  - Determinism work is largely done and was done for this reason without\n    knowing it: gotcha 18 (DataStore iteration order, analyze_records first-seen\n    order) and gotcha 37b (a gp fit records seed AND FitConfig, because the same\n    seed under a different config lands on a different tree).\n  - THERE IS NO RECORDER. parse.rs parses a script; nothing writes one.\n\nSO THE WORK IS (a) the recording side, and (b) closing the paths that bypass the\ncommand layer.\n\nTHE HARD QUESTION, WHICH THE ADR MUST ANSWER FIRST: WHICH VOCABULARY IS RECORDED?\nThere are THREE command-ish layers and they are not interchangeable:\n  1. `Cmd` -- a NAME plus args, resolved against a CmdContext. The Emacs\n     analogue, and what `improvise script` already replays.\n  2. `Effect` -- the resolved mutation, the only thing that touches App.\n  3. `Command`/`ModelCommand` -- the WIRE vocabulary, derived from the effects.\n\nGotcha 38 draws the line that matters: A KEYMAP LOOKUP CANNOT RETURN A `Command`,\nbecause a binding names an INTENT resolved against a CmdContext (\"move-cursor\ndown\") while a Command is the RESOLVED MUTATION (\"SetSelected{row,col}\").\nimprovise-gxi's AC 4 asked for something that split forbids.\n\nThat cuts both ways for replay:\n  - Recording layer 1 is small, human-readable and editable, and replays only if\n    the CONTEXT evolves identically -- which is the Emacs model and is fine from\n    a known start state.\n  - Recording layer 2 or 3 is robust to context drift but is not \"commands\" in\n    the user's sense, and a log of SetSelected{3,4} is not something a person\n    reads or edits.\nThe ADR should probably choose layer 1 and say what that costs.\n\nWHAT BREAKS REPLAY TODAY -- enumerate before designing:\n  - ANY ACTION THAT DOES NOT GO THROUGH A COMMAND. Audit for it: the browser's\n    click surfaces compose Commands (Click::PageItem does), but viewport/resize,\n    the ResizeObserver, and the OPFS persist trigger are observations rather than\n    commands. Decide whether an observation must become a command or is outside\n    the log by construction.\n  - EXTERNAL INPUT. LoadModel(path) and the import wizard read files; replay\n    reproduces the state only given the same inputs. Does the log reference them,\n    or must it capture them?\n  - TIME AND RANDOMNESS. A gp fit already records seed + config; anything else\n    that samples a clock or an RNG has to.\n  - MULTI-CLIENT. \"The state of the whole SYSTEM\" with several sessions means the\n    log has to carry WHO acted, which is ADR 001's addressed-command question\n    from a new direction -- and gotcha 29 says the model is shared and the UI is\n    not, so a replay reproducing every client's UI needs per-session logs.\n\nWHAT THE PROPERTY BUYS, and why it is worth the ADR: a replay harness is the\nstrongest possible regression test for this codebase -- record a session, replay\nit, diff the resulting document. It would have caught the whole class this repo\nkeeps rediscovering (a test that passes while the thing it names is broken),\nbecause a replay diff cannot be vacuous.\n\nDO NOT START BY WRITING A RECORDER. Start by auditing what currently bypasses the\ncommand layer, because that list decides whether the property is reachable at all.","notes":"TWO REFINEMENTS FROM THE USER, 2026-09-22, and the second changes what this bead\nis:\n\n  \"(Ignoring nondeterminism like rng seeding)\"\n  \"This was how the app used to work, but maybe the web refactor broke it\"\n\nSO RNG/CLOCK DETERMINISM IS OUT OF SCOPE. Strike that bullet from the enumeration\nabove; a gp fit's seed+config recording (gotcha 37b) is a separate concern and\nalready handled.\n\nAND THIS IS ARCHAEOLOGY, NOT DESIGN. The property existed. The first task is to\nfind WHEN and WHERE it stopped holding, not to invent a mechanism. That reframes\nthe whole bead: start with `git log` and a bisect-shaped question, not with a\nrecorder.\n\nWHAT THE WEB WORK INTRODUCED THAT IS A CANDIDATE, found in a first pass:\n\nThe browser refactor deliberately replaced several hand-kept tables with\nOBSERVATIONS, and each is a state change that happens WITHOUT A COMMAND FIRING:\n  - App::document_generation += 1   (app.rs:444, bumped by install_workbook)\n  - App::cursor_epoch += 1          (app.rs:653, on cursor invalidation)\n  - App::layout_version += 1        (app.rs:945, per LayoutGeometry effect)\n  - view_frame / view_frames        (app.rs:73-124) -- the cursor is invalidated\n    by OBSERVING the grid's frame (gotcha 24, improvise-ni6k), which is why no\n    effect calls reset_cursor any more\n  - model_state.dirty raised in apply_effects off EffectKind (gotcha 45), which\n    is why MarkDirty was DELETED as an effect\n\nEACH OF THOSE WAS A DELIBERATE MOVE AND THE ARGUMENT FOR IT IS GOOD: a table of\n\"which effects renumber the grid\" is a second description free to disagree with\nthe first, so the repo chose to observe instead. Gotchas 24, 39 and 45 all say\n\"observed, not predicted\" in as many words.\n\nSO THERE IS A REAL TENSION TO RESOLVE IN THE ADR, and it is the interesting part:\n\"everything is a command\" and \"observe rather than predict\" pull in opposite\ndirections.\n\nBUT PROBABLY NOT A CONTRADICTION, and the ADR should test this claim first\nbecause it may dissolve the whole problem: AN OBSERVATION IS A PURE FUNCTION OF\nSTATE. If replaying the commands reproduces the state, every observation\nre-derives identically and nothing is lost. Observations are DERIVED, not\nprimitive, so they do not need to be in the log -- they need to be REPRODUCIBLE\nFROM it. That is a weaker and much cheaper requirement.\n\nWHAT WOULD GENUINELY BREAK REPLAY is an action whose result is NOT determined by\nthe command sequence. The candidates to audit, in order:\n  - VIEWPORT EXTENT. Client::set_viewport records what the PAGE announced, off\n    the browser window size and a ResizeObserver. That is external input, not a\n    command, and gotcha 47 says it is \"not derivable\". A replay on a different\n    window size gets a different extent -- and therefore a different projected\n    grid.\n  - EXTERNAL FILES. LoadModel(path) and the import wizard read the filesystem;\n    replay reproduces state only given the same inputs.\n  - MULTI-CLIENT ORDERING. \"The state of the whole system\" with several sessions\n    needs the log to carry WHO acted and in what order -- ADR 001's addressed-\n    command question from a new direction.\n\nFIRST CONCRETE STEP: `improvise script` already replays a command sequence into a\nfresh process (src/main.rs::run_headless_script, one function with\nrun_headless_commands since PR #131). So the check is cheap -- take a document,\ndrive it with a script, and see whether the result is reproducible. If it is, the\nTUI path still holds the property and the regression is browser-side only, which\nnarrows the search to the list above.\nAUDIT COMPLETE 2026-09-22 (read-only, base a9cad15). Baseline measured on the auditing host: 1699 passed / 0 failed / 7 ignored over 38 binaries, longest single binary 0.70s.\n\nTHE USER'S HYPOTHESIS IS WRONG FOR THE MAIN DEFECT. Replay is broken, but not by the web refactor: see improvise-6uva, broken by 35946af on 2026-04-04, five months before the first wasm-client commit.\n\nTWO DEFECTS FOUND, FILED SEPARATELY: improvise-6uva (script cannot move the cursor) and improvise-up8g (viewport extent is external on both front ends). THE SECOND IS MASKED BY THE FIRST -- fix 6uva and up8g becomes live, so they must be closed together or the repair will look like it works and then be flaky.\n\nTHE TICKET'S STATED SAFETY ARGUMENT IS FALSE, and the false version is dangerous. The ticket claims \"an observation is a pure function of state\". IT IS NOT -- it is a pure function of the TRAJECTORY. Measured, two routes to an IDENTICAL document:\n  no commands                                      -\u003e layout_version 0, cursor_epoch 0, dirty false\n  set-axis Product column, then set-axis Product row -\u003e layout_version 2, cursor_epoch 2, dirty true\nThe weaker true claim (\"reproducible from the log\") is all replay needs. But the stronger false one is exactly what you would cite to justify SNAPSHOT-PLUS-SUFFIX LOG COMPACTION, and that would be wrong, silently, in the direction that looks like it works: Basis puts document_generation and layout_version ON THE WIRE and clients compare them for equality, so a compacted replay is not basis-compatible with any client holding a claim. model_state.dirty is the same shape and is the worker's OPFS persist trigger (gotcha 45), so a replay reaching the same document by a different route persists a different number of times.\n\nGOTCHA 40 IS STALE, and the truth is stronger than the doc. It says layout_version bumps \"per ModelChange::LayoutGeometry effect\". It actually bumps from an OBSERVED view_shapes diff (observe_reshape, app.rs:938), so three idempotent set-axis calls bump nothing and batching two real changes into one line or two gives the same 2. The observed form is what the ADR should lean on. Correction applied to context/repo-map.md.\n\nDETERMINISM OTHERWISE CHECKS OUT: no clock or RNG is reachable from any command or effect except App::last_autosave (Instant::now(), debounce only, writes to a separate autosave_path and never the document), and fit-measure takes its seed as an explicit argument with a fixed default. One genuine clause-1 violation that costs replay nothing: autosave_if_needed writes a file on a wall-clock timer with NO COMMAND FIRING, so \"everything is a command\" is literally false there.\n\nTHE FIVE GENUINE EXTERNAL INPUTS, ranked by cost to close:\n1. Viewport extent (improvise-up8g) -- cheapest, one pair of integers, already has a wire spelling.\n2. Document identity at startup (get_initial_workbook, -f \u003cpath\u003e) -- cheap: the log header names the starting document by content hash.\n3. External files mid-session (LoadModel, ExportCsv, SaveAs, ImportJsonHeadless, StartImportWizard) -- moderate. Storage is ALREADY the seam (gotcha 2), so a Storage that replays recorded bytes is a clean mechanism needing no effect change.\n4. Import-wizard interaction -- moderate/hard: the keys go through a command but the wizard state is session-local residue with no Projection. Replayable in principle; nothing tests it.\n5. Multi-client ordering and authorship -- HARDEST, and partly a design question. apply_model's basis check means a differently-interleaved replay can REJECT a batch the original accepted, so the log must carry SessionId AND the arrival order across sessions.\n\nWHICH VOCABULARY TO RECORD -- the ADR's central question. The auditor's reading, offered for the ADR to accept or reject: the user's ruling has two clauses wanting different layers. Clause 1 (\"everything is a command, like Emacs\") is a LAYER-1 discipline about what a user can type, bind and read. Clause 2 (\"replay reproduces any state\") is a LOG property, and LAYER 3 (Command/ModelCommand) is strictly better at it -- already Serialize/Deserialize, already carries a Basis, already has one door and one interpreter, already transactional via ClientFrame::Commands, and ALREADY WHAT THE BROWSER EMITS. Note a layer-1 log CANNOT BE PRODUCED BY THE BROWSER AS BUILT: gotcha 38 says a keymap lookup cannot return a Command, so the browser resolves keys to layer 3 and never constructs a layer-1 name.\nThe two are not in conflict if the log records layer 3 and layer 1 keeps its status as the human surface, with ExecuteCommand being just another producer of layer-3 traffic. WHAT THAT COSTS is closing layer 3's three DELIBERATE holes -- ApplyAndClearDrill and AcceptWizardModel off the wire (gotcha 38), ClientFrame::Save a frame not a command (gotcha 45), SwitchView carrying no basis -- each of which has a written argument that would have to be REOPENED. That is the real price and belongs in the ADR rather than being discovered later.\nLayer 2 (Effect) declined: 58 types, no text syntax, no parser, no Serialize, and a log of effects cannot be edited by a person, which is most of what the user asked for.\n\nNOT VERIFIED: the browser half was not driven (no Playwright, no wasm build) -- everything about Client::set_viewport is read, not run, though the TUI analogue WAS run and is the same mechanism. Multi-client interleaving was not exercised. The import wizard was not replayed. No bisect between 35946af and HEAD for ADDITIONAL regressions -- a second archaeology pass after 6uva is fixed is cheap and is where to look next. Only two terminal sizes probed.","status":"in_progress","priority":2,"issue_type":"task","assignee":"agent-adr006","owner":"el-github@elangley.org","created_at":"2026-09-23T00:55:57Z","created_by":"Edward Langley","updated_at":"2026-09-25T04:45:22Z","started_at":"2026-09-25T04:45:22Z","lease_expires_at":"2026-09-25T04:50:22Z","heartbeat_at":"2026-09-25T04:45:22Z","dependencies":[{"issue_id":"improvise-ilvl","depends_on_id":"improvise-31oe","type":"parent-child","created_at":"2026-09-25T01:05:08Z","created_by":"Edward Langley","metadata":"{}"}],"dependency_count":0,"dependent_count":0,"comment_count":0}

You can use a nix shebang line\n(nix-shell manpage has details here).\"\n\nWHY, MEASURED RATHER THAN ASSERTED. improvise-xgra (PR #133) shipped two bugs that\nwere invisible on the machine that wrote them:\n  - `local n=\"$1\" name=\"$2\" f=\"...$n...\"` is NOT left-to-right on bash 5 -- every\n    name is created before the assignments run, so $n is unbound under set -u.\n  - macOS ships bash 3.2 (2007, GPLv2, frozen), where it works.\nRESULT: scripts/pr-reviews-test.sh passed 19/19 LOCALLY AND 2/19 IN CI ON THE SAME\nCOMMIT. Both bugs surfaced as exit 2 with no output, because a dead command\nsubstitution hands jq an empty --argjson and jq answers with a USAGE error.\n\nTHE INVENTORY, as of 22ab58f: 16 scripts, with 11 `#!/usr/bin/env bash`,\n4 `#!/bin/sh` and 1 `#!/usr/bin/env sh`. So the bash/sh split is already\ninconsistent, and the sh ones are running as macOS bash-in-sh-mode locally and\ndash in CI -- a SECOND undetected platform difference of the same kind.\n\nTHE TWO OPTIONS THE USER NAMED:\n  a. A NIX SHEBANG, e.g.\n       #!/usr/bin/env nix-shell\n       #!nix-shell -i bash -p bash\n     which pins ONE bash for every developer and CI alike. Cost: nix-shell\n     startup on every invocation, which matters for scripts CI runs per job and\n     for anything in a tight loop -- MEASURE IT before committing, and say what it\n     costs on a cold and a warm store.\n  b. ZSH, which macOS ships current and which is the login shell there. No startup\n     cost, but it is a different language in the places that bite (word splitting,\n     array indexing from 1, `setopt` needed for sh-compatible globbing), so\n     PORTING IS NOT A SHEBANG CHANGE -- every script would need reading.\n\nDECIDE ONE AND APPLY IT UNIFORMLY. A per-script choice reintroduces exactly the\ninconsistency above.\n\nCHECK BEFORE CHOOSING, because it may decide it:\n  - Does CI have nix on every job that runs a script? The kb job uses\n    `nix shell nixpkgs#trealla`, so nix is present there; confirm for build, test\n    and browser.\n  - Does the git merge driver (scripts/beads-merge-driver.sh) tolerate a\n    nix-shell startup? It runs inside git's merge machinery.\n  - Does .envrc / direnv already put a nix bash on PATH? If so, `#!/usr/bin/env\n    bash` may already be correct INSIDE the dev shell and wrong only outside it --\n    which would make the fix \"run scripts through direnv\" rather than a shebang\n    change, and would be cheaper than either option.\n\nWHATEVER LANDS, THE GUARD IS THE POINT: the bug this closes was invisible to a\nlocal run, so the fix must be verified by something that RUNS BOTH SHELLS, or by\npinning so there is only one.

But pkgs.mkShell ALSO EXPORTS ~30\nGENERICALLY-NAMED LOWERCASE VARIABLES THE RUNNER DOES NOT HAVE -- name, out,\noutputs, system, shell, builder, stdenv, phases, patches, buildInputs, doCheck,\nstrictDeps and more.

A fix aimed only at the shell would have\nshipped.\n\nVERIFIED BY THE ORCHESTRATOR, and my first check was confounded: `nix shell\nnixpkgs#bash` appeared to set `name` too, until I re-ran with `env -u name` and\nit came back UNSET while `direnv exec .` still gave nix-shell-env. My check had\ninherited the variable from my own direnv-loaded shell -- it answered \"does name\nend up set\" where the question is \"does nix shell set it\". The agent's control\nwas right and mine was not.\n\nTHE NIX SHEBANG WAS DECLINED ON AVAILABILITY, NOT SPEED. Measured warm, 20\ninvocations: ambient `bash -c true` 5.1ms; `nix shell nixpkgs#bash --command`\n61.8ms; `nix-shell -p bash --run` (THE MANPAGE FORM) 675.2ms, 132x. 675ms inside\ngit's merge machinery for beads-merge-driver.sh is bad -- but the decider is that\nNIX IS ON ONLY THE kb JOB. build, test, wasm, js, harness-lint, browser and\npages-deploy have none, so a nix shebang needs install-nix-action added to three\nmore jobs, paid every run, to reach a bash those runners already ship. zsh\ndeclined too: not a shebang change, sixteen scripts to read, and no zsh on the\nrunner either.\n\nWHAT LANDED: scripts/checkers.sh, the ONE entry point for every check_the_checker,\ncalled verbatim by CI and by the local gate.

{"_type":"issue","id":"improvise-clso","title":"Ctrl-S saves and also opens the browser's own save dialog","description":"Found by the improvise-jz6w agent (PR #134) as a consequence of its own fix, and\ncorrectly NOT fixed there because every available fix crosses a doctrine line.\n\nNOT A REGRESSION -- verified by the orchestrator. web/app.js:786 calls\npreventDefault only when `!e.ctrlKey \u0026\u0026 !e.altKey`, with the deliberate comment\n\"Ctrl/Alt combinations are left alone: they are the browser's\". So Ctrl-S ALWAYS\nopened Chrome's \"Save page as\" dialog; before improvise-jz6w it did that and\nnothing else. Now it saves the document AND opens the dialog. The save is\ncorrect; the dialog is the wart, and it is newly VISIBLE rather than newly\nintroduced.\n\nWHY IT WAS NOT FIXED IN #134, and this is the useful part:\n  - Parsing the frame in app.js gives the page PROTOCOL KNOWLEDGE\n    (design-principles section 5).\n  - A `e.key === \"s\" \u0026\u0026 e.ctrlKey` test puts a KEYBINDING FACT in the page.\n  - Widening the wasm surface so Rust can say \"this key is claimed exclusively\"\n    is a new decision the ticket did not authorise.\n\nTHE HONEST SHAPE: the DECISION -- \"is this key exclusively claimed by the app?\" --\nbelongs in Rust as a third thing a resolver already knows, beside Local and\nRequest. That is a natural follow-up to the KeyOutcome variant #134 added, not a\npatch to app.js.\n\nWHATEVER LANDS, THE ASSERTION GOES IN harness/tests/shell.spec.js (gotcha 48: a\nchange to web/*.js belongs in that spec directory). Note harness/node_modules does\nnot exist in a fresh worktree, so `npx playwright test` fails with an error about\nthe PACKAGE rather than the harness -- run npm install in harness/ first.\n\nCHECK BEFORE BUILDING: whether any other Ctrl chord is now in the same position.\nThe preventDefault rule is blanket, so the answer is \"every Ctrl binding the\nresolver claims\", and today that is one.","notes":"SECOND INSTANCE, AND IT IS WORSE: Ctrl-W. Found by the improvise-htl6 agent while hunting for a free key; verified by the orchestrator at keymap.rs:611 --\n\n  normal.bind_args(KeyCode::Char('w'), ctrl, \"enter-mode\", vec![\"save-prompt\".into()])\n\nwith the comment \"Ctrl-S saves to the known path; Ctrl-W asks for one\" (improvise-lae).\n\nIN A BROWSER, Ctrl-W CLOSES THE TAB. Same mechanism as the Ctrl-S wart -- web/app.js calls preventDefault only when !e.ctrlKey \u0026\u0026 !e.altKey -- but the consequence is not a spurious dialog the user dismisses, it is THE DOCUMENT'S TAB CLOSING. Whatever the save prompt does is invisible, because the surface it would draw on is gone.\n\nTHE GENERALISATION, which is why this belongs here rather than in its own ticket: THE KEYMAP IS SHARED BETWEEN THE TWO FRONT ENDS (improvise-bpq2, gotcha 47), so a Ctrl- chord chosen for a terminal is one the browser must live with, and the browser has a reserved set the terminal does not. Ctrl-R (reload), Ctrl-S (save page), Ctrl-W (close tab), Ctrl-T, Ctrl-N are all browser-owned. So the fix for this ticket should be stated over the CLASS -- what happens to a browser-reserved chord in a shared keymap -- rather than per key, or a third instance arrives the next time somebody needs a free Ctrl- binding.\n\nNote the constraint that makes this hard is already recorded above: every available fix crosses a doctrine line, because preventDefault-ing selectively needs the page to know which chords the app binds, which is protocol knowledge (design-principles section 5). The shared keymap is where that knowledge already lives, which is a hint at where the answer is.\n\nALSO WORTH RECORDING: Ctrl-R is NOT bound today, and the htl6 agent deliberately did not take it for view-forward for exactly this reason -- it chose ',' instead. So this ticket has already changed one decision.\nANALYSIS 2026-09-22 by agent-helpkeys2 (NOT fixed; this needs a ruling). Read at gh/main 4d71c01.\n\nTHE DECISION IS ALREADY IN RUST. web/app.js calls preventDefault when on_key_event returns a frame, and a frame exists only when resolve() claimed the key (Local/Request/Upstream; Ignored gives none). The ONLY keybinding knowledge in the page is the extra rule `if (!e.ctrlKey \u0026\u0026 !e.altKey)` at app.js:786. So the obvious fix is to DELETE page knowledge, not add it: preventDefault whenever a frame comes back, whatever the modifiers. That fixes Ctrl-S (and Ctrl-d/Ctrl-u, which today scroll the grid AND whatever the browser does) with no protocol knowledge in the page. It is not safe to ship alone, for the reason below.\n\nTHE CLASS HAS THREE MEMBERS, not one, and they want different answers:\n\n1. PREVENTABLE chords the app binds on purpose (Ctrl-S, Ctrl-d, Ctrl-u; Ctrl-R/Ctrl-P/Ctrl-F if ever bound). Answer: the page honours the claim, per above. Rust already decides.\n\n2. UNPREVENTABLE chords (Ctrl-W, Ctrl-T, Ctrl-N, Ctrl-Shift-T/N/W, Ctrl-Tab; Ctrl-Q on Linux Chrome). Believed, NOT measured here: Chromium does not deliver these to a normal tab's keydown at all, and preventDefault cannot stop them. So no page code fixes Ctrl-W. Its consequence is also narrower than the note above suggests: `enter-mode save-prompt` is a mode `declined` refuses in the browser anyway, it is advertised nowhere the browser paints (not in advertised(), not in help pages), and the worker persists every accepted command to OPFS, so a closed tab loses nothing. The rule this member needs is a KEYMAP rule: a command bound only to a browser-reserved chord is unreachable in a browser, so it must have a second key or be one the browser declines. That is checkable in resolve.rs's tests over the shared keymap, given a named list of reserved chords (a fact about browsers, living beside BrowserKey).\n\n3. ACCIDENTAL claims through the AnyChar fallback. Keymap::lookup_local retries a modified Char without its modifiers and then falls to AnyChar, so in every text-entry mode Ctrl-C, Ctrl-V, Ctrl-R, Ctrl-L TYPE A LETTER — pinned on purpose by resolve::tests::a_modified_character_now_types_because_the_fallback_is_the_shared_one (Ctrl-x types 'x'). Today, in a browser minibuffer, Ctrl-V types 'v' AND pastes; Ctrl-R types 'r' AND reloads. Applying fix 1 alone would make it type 'v' and SUPPRESS the paste — strictly worse. So fix 1 is blocked on a ruling about member 3.\n\nTHE RULING NEEDED (the user's, not an agent's): should a Ctrl/Alt-modified character reach AnyChar at all? Options:\n (A) No: lookup_local stops retrying Ctrl/Alt-modified Chars as bare/AnyChar. Shared table, so the TUI changes too (Ctrl-x in the TUI minibuffer stops typing x — probably correct there as well). Risk: AltGr on Windows arrives as Ctrl+Alt, so international characters (e.g. @ on a German layout) would stop typing in the browser; BrowserKey would need to treat ctrl\u0026\u0026alt as AltGr and drop both. Then fix 1 is safe and the page loses its modifier rule.\n (B) Browser-only: BrowserKey (wasm-client/keys.rs) drops Ctrl-modified printable characters before resolve, the way it already drops Meta. No shared-table change; the TUI keeps today's behaviour; the page's rule moves into Rust where it is testable. Then fix 1 is safe.\n (C) Keep typing modified chars, keep the page rule, and fix only Ctrl-S by making Request outcomes claim regardless of modifiers. Smallest, but it is per-key again, which is what this ticket asks not to do.\nRecommended by this agent: (B) + fix 1 + the member-2 keymap guard; (A) is cleaner but changes the TUI and needs an AltGr decision.\n\nWhatever lands, the assertion belongs in harness/tests/shell.spec.js (gotcha 48) and needs `npm install` in harness/ first.","status":"open","priority":2,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-22T20:59:53Z","created_by":"Edward Langley","updated_at":"2026-09-23T04:22:55Z","labels":["browser"],"dependencies":[{"issue_id":"improvise-clso","depends_on_id":"improvise-fhj0","type":"parent-child","created_at":"2026-09-25T01:05:37Z","created_by":"Edward Langley","metadata":"{}"}],"dependency_count":0,"dependent_count":0,"comment_count":0}

{"_type":"issue","id":"improvise-n6t8","title":"Header layout must be reserved, not fitted: the mode pill, the hint and the status all reflow","description":"USER 2026-09-22: \"the top bar jumps around a lot because the layout isn't fixed\nenough: The messages like 'the command line is not available in the browser yet'\nshould be toasts that do not cause relayout and should disappear eventually\n(maybe where the minibuffer is?)\"\n\nHOW IT WORKS TODAY, read before filing:\n  - web/shell.js::composeStatus joins TWO independent facts into #status with\n    \" . \": `shell` (the transport -- \"in-page worker\") and `model`\n    (RenderModel::status, which is ViewState::status_msg). They are composed\n    rather than overwritten deliberately, so a repaint cannot silently erase a\n    connection error (gotcha 46).\n  - #hint also carries variable-width content, one line per mode, off\n    help::hint_line.\n  - Both live in the flex \u003cheader\u003e. So the bar reflows when EITHER a status\n    message arrives or the MODE changes -- the second is worth naming because it\n    reflows even with no message at all.\n\nTHE TRAP IN THE OBVIOUS FIX, and it is the thing to get right:\nViewState::status_msg is STATE, not an event. web/app.js's repaint() calls\nshell.setModel(model.status) unconditionally, and repaint() runs on every\nkeydown. So a toast dismissed on a timer RESURRECTS on the next keypress, because\nnothing cleared the underlying string -- and Rust only replaces status_msg when\nsome later command sets one. A naive setTimeout(hide) produces a message that\nflickers back whenever the user does anything, which is worse than a message that\nsimply stays.\n\nSo dismissal must be keyed to MESSAGE IDENTITY (\"I have already shown this\nstring\") rather than to a timer alone, or the same string arriving genuinely\ntwice must be distinguishable from a repaint of the old one. Decide which, and\nsay so -- if two identical messages in a row should both be shown, identity alone\nis not enough and something must carry a sequence.\n\nSCOPE -- PRESENTATION ONLY, and that is a deliberate limit. Do NOT split\nstatus_msg into transient-vs-persistent in ViewState. That is a protocol change\nwith a portability argument attached (gotcha 30), the TUI shows status_msg in its\nbottom bar where it costs no layout at all, and nothing here forecloses it later.\nThe browser's problem is where it draws the string, not what the string is.\n\nTHREE THINGS THE FIX OWES:\n  1. THE HEADER MUST STOP REFLOWING ON ITS OWN, independently of toasts. #hint\n     changes per mode, so a fixed/reserved layout is needed regardless. Reserving\n     space is the fix; making the text shorter is not.\n  2. THE TOAST MUST NOT TAKE PART IN LAYOUT AT ALL -- out of flow, so it cannot\n     push anything.\n  3. THE CONNECTION-ERROR FACT MUST SURVIVE. composeStatus exists because a\n     repaint used to erase it. A toast that auto-hides must not take a transport\n     failure with it: \"disconnected\" is not transient and must stay visible.\n     That is the mirror of the bug gotcha 46 records.\n\nPLACEMENT: the user suggests near the minibuffer. PR #120 put the minibuffer as a\nraised bordered card over the grid, so that region is consistent -- but DECIDE\nWHAT HAPPENS WHEN BOTH ARE PRESENT. A user typing in the minibuffer who triggers\na status message must not have the prompt covered or displaced. Say what you\nchose.\n\nTESTABLE, and therefore required: harness/tests/ can assert that the header's\nbounding box does not change when a status message arrives and when the mode\nchanges (the two reflow causes above), and that the toast overlaps rather than\ndisplaces. gotcha 48: a change to web/*.js belongs in that spec directory. The\ncolour and the animation are not testable there and should be argued instead.\n\nSEQUENCING: branch ui/page-menu is in flight and owns web/app.js, web/shell.js\nand web/style.css. START THIS AFTER IT LANDS, or expect a conflict in all three.","notes":"USER 2026-09-22, widening this ticket: \"the other display annoyance is that the\nnormal/categories/etc. pill changes sizes constantly: it should have a fixed\nallocated size and not move the layout around. As a general rule, there shouldn't\nbe motion of layout elements I expect to be fixed.\"\n\nSO THIS TICKET IS NOW ABOUT HEADER LAYOUT STABILITY GENERALLY, and the toast is\none instance of it. THE RULE IS THE DELIVERABLE, not three separate patches.\n\nTHREE KNOWN MOVERS, all in the flex \u003cheader\u003e:\n  1. THE MODE PILL. Its label comes from AppMode::label() -- NORMAL, CATEGORIES,\n     FORMULA, INSERT, RECORDS, ... -- and the pill is sized by its text, so every\n     mode change resizes it and shifts everything after it.\n  2. #hint. One line per mode off help::hint_line, so it reflows on the same\n     event as the pill, compounding it.\n  3. #status. Composed from the transport fact and ViewState::status_msg (see\n     the original description).\n\nTHE OBVIOUS FIX IS THE FRAGILE ONE, AND IT WILL BE CHOSEN BY DEFAULT: a\nhardcoded min-width in ch, sized by eye to today's longest label. That silently\nresumes the jitter the day an AppMode variant with a longer label is added.\nAppMode's per-variant facts are exhaustive-match methods, so the COMPILER makes\nyou fill in label() for a new variant (repo-map, AppMode) -- but nothing anywhere\nchecks that the CSS still fits it. The gap between \"the compiler caught the Rust\"\nand \"the pixel is wrong\" is exactly where this regresses.\n\nSO THE GUARD IS THE POINT, and it is genuinely testable: a Playwright spec that\nwalks every reachable mode and asserts the header's bounding box -- and the left\nedge of the element AFTER the pill -- do not change. That catches a new long\nlabel, not just today's set. Prove it discriminates by injecting a mode label\nlonger than the reserved width and watching it fail. Without that injection this\nis a test that passes because nothing moved anyway.\n\nNote which modes a browser can actually reach: improvise-6acs and improvise-y11g\nmean some text-entry modes are not reachable there yet, so a spec that walks\n\"every mode\" may be walking four. Say how many it really covered -- an\noverstated scope is worse than a narrow one honestly described.\n\nTHE GENERAL RULE TO WRITE DOWN, since the user stated it as one: an element whose\nCONTENT varies but whose POSITION the reader treats as fixed must have its space\nRESERVED, not fitted. That covers the pill, the hint, the status, the document\ntitle and the view chip, and it is the reason a toast must be out of flow rather\nthan merely short.\nFIXED in PR #127 (merge d46ec59).\n\nTHE TICKET'S FRAMING WAS WRONG ABOUT WHICH ELEMENT COMPOUNDED, and the spec found\nit rather than the author. The ticket (and the user's report) named the mode pill.\nOn its first run the new spec failed on the header's HEIGHT: #status was\nflex: 0 1 auto beside a flex: 1 1 auto hint, so a longer hint took the shrink out\nof #status, which WRAPPED TO TWO AND THEN THREE LINES -- 52.5px to 71.0px. THE\nOLD HEADER WAS TWO LINES TALL AT NORMAL WITH NO MESSAGE AT ALL.\n\nSo reserving the pill alone would have left the bar moving and the PR would have\nshipped looking correct. Fixed with flex: 1 1 0 on the hint (zero basis, absorbs\nthe remainder, contributes nothing to overflow) and nowrap + flex: 0 0 auto on\n#status.\n\nTHE RESERVE IS A FLOOR, NOT A CAP, and that is the load-bearing choice: a width\nor max-width absorbs an over-long value inside a box that never grows, so every\nbounding-box measurement stays identical and the regression is INVISIBLE. min-width\nlets an over-long mode label grow the box, which is the only way the guard can see\nit. Proved by injection: removing the 21ch reserve fails \"the bar moved in\nCATEGORIES\" AND the 16-char check-the-checker.\n\nDISMISSAL IS KEYED ON WHAT WAS LAST ACCEPTED, not on a timer, because\nViewState::status_msg is STATE re-offered by every repaint. Consequence, stated\nrather than hidden: TWO IDENTICAL MESSAGES IN A ROW SHOW ONCE. That is forced --\nnothing beside status_msg carries a sequence, model.revision moves for a cursor\nkey as readily as for a re-issued command, and of the two readings of an ambiguous\noffer only one avoids reintroducing the reported bug. A sequence number is the\nprotocol change the scope forbade.\n\nGOTCHA 46 IS NOW STRUCTURAL RATHER THAN CONVENTIONAL. composeStatus is DELETED:\nthe transport fact and the document fact go to two ELEMENTS, not one string joined\nwith a separator, so a repaint reaches onModel and CANNOT ADDRESS onShell AT ALL.\nThe join's unit test was REPLACED, not dropped -- \"a repaint's model status cannot\nreach the transport's sink at all\", verified present by the orchestrator. A\nseparation with no guard is how one regresses into a single sink.\n\nNINE MODES WALKED, not the four I guessed: NORMAL, CATEGORIES, FORMULAS, VIEWS,\nTILES, HELP, INSERT, NEW CATEGORY, FORMULA. Excluded with reasons:\nSavePrompt/ExportPrompt/CommandMode refused by resolve::stranding, records mode\ndeclines out loud, ImportWizard has no browser entry, Quit is not a screen. Each\niteration asserts #mode BEFORE measuring, so a key that failed to reach its mode\ncannot make the comparison vacuous.\n\nMINIBUFFER AND TOAST COEXIST: #bottom-dock is position: fixed and anchored at its\nBOTTOM, stacking upward. The minibuffer's box is byte-identical with and without a\ntoast. A top-anchored stack, or an offset from the minibuffer's height, would both\nhave moved the prompt.\n\nTHE TOAST KEEPS ITS TEXT WHEN IT HIDES, deliberately: the element is the record of\nwhat was last said, and drill.spec.js's discrimination between two refusals reads\nit -- an emptied node would satisfy not.toContainText(\"aggregate\") VACUOUSLY the\nmoment the timer fired.\n\nNOT VERIFIED: prefers-color-scheme is exercised nowhere (dark was screenshotted by\nhand; pre-existing, now stated in clients.md). Colour, contrast, spacing and the\ngrouped/multi-level header DOM remain argued. Text ALIGNMENT inside a fixed box is\ninvisible to a bounding-box guard -- honest scope, not a gap.

Also have a down-arrow indicating there's a\nmenu.\"\n\nTHE GOOD NEWS, VERIFIED BEFORE FILING: almost everything needed already exists.\nThis is NOT a protocol change and needs no new derivation.\n\n  - improvise_core::view::layout::PageAxis ALREADY carries\n    `items: Option\u003cVec\u003cString\u003e\u003e` -- Some exactly for Axis::Page, None for a\n    Filter axis, which constrains without being navigable (gotcha 27). So the\n    ITEM NAMES ARE ALREADY PROJECTED: GridCache::page_coords is Vec\u003cPageAxis\u003e.\n  - ModelCommand::SetPageSelection { .. } ALREADY EXISTS on the wire\n    (improvise-protocol/src/reduce.rs:127), and is in records_named's match at\n    :185. So the mutation half is done.\n\nTHE ONE GAP is that the browser THROWS THE NAMES AWAY. wasm-client/src/render.rs\nRenderPageAxis (:157) keeps `cat`, `selected` and `cycle: Option\u003cRenderPageCycle\u003e`,\nand RenderPageCycle (:168) is `{ at: usize, count: usize }` -- a POSITION and a\nCOUNT. That was enough for improvise-p1ym, which asked \"can [ and ] cycle\"; it is\nnot enough for \"can the user pick\", which needs the names.\n\nSo: widen RenderPageAxis to carry the item names it is already handed. That is a\npass-through, not a second derivation -- the names come from the projection, and\nnothing in the browser may compute them (design-principles section 5).\n\nTHEN THE UI, which is the actual work:\n  - a down-arrow affordance on a page chip that HAS a menu. Note the affordance\n    must follow `items.is_some()`, NOT the presence of a page bar entry: a Filter\n    axis appears in page_coords and must NOT get an arrow, because there is\n    nothing to pick. Getting that wrong offers a menu that cannot do anything.\n  - click opens a menu of the items; choosing one composes\n    Command::Model(SetPageSelection{..}).\n  - the currently selected item should be marked in the menu.\n\nEVENT HANDLING: the user has already ruled on the shape (improvise-b8ot) -- one\ndelegated handler per surface on a stable root, not one listener per node, and\nIDs/classes/data attributes as needed to disambiguate. A menu built with per-node\nlisteners would be new work in exactly the style b8ot exists to remove. Read b8ot\nbefore starting, and prefer landing this in the shape b8ot wants rather than\nadding another per-node listener to migrate later.\n\nKEYBOARD: the menu must be operable without a mouse, and must not swallow keys\nthe grid needs. web/app.js's window keydown handler returns early when `editing`\nis true; a menu is a third mode of that kind and needs the same treatment or it\nwill eat hjkl. Say which you chose.\n\nNOT IN SCOPE, adjacent, filed separately or noted:\n  - the TILE bar above it (the \"Quarter Pag\" chips) is a different widget. Its\n    three-character labels come from Axis::short_label(), which exists so the\n    TUI's tile bar has fixed-width columns; in a browser that reads as a\n    truncation bug. Axis::plain_label() already says \"Page\". That is a separate\n    change and NOT this ticket.","notes":"FIXED in PR #123 (merge 7470b61).\n\nTHE DESIGN DECISION WORTH KEEPING: `items` is relayed INSIDE `cycle`, not beside\nit. One predicate, not two. A Filter axis has no cycle, so it gets no arrow, no\nmenu, no items, is painted as a \u003cspan\u003e rather than a \u003cbutton\u003e, and\nClick::PageItem composes nothing if a click reaches it -- FOUR answers off\nPageAxis::cycle, the one home gotcha 27 already named. `items.is_some()` appears\nnowhere. That is stronger than the guard I asked for in the brief, which was a\ntest that a Filter axis gets no arrow: here the wrong state is not constructible.\n\nEvery test carries a Filter axis beside the Page one, and the pass-through fault\n(items: Vec::new()) is caught by\nrender::tests::a_navigable_page_axis_relays_the_items_it_may_be_fixed_to.\n\nKEYBOARD: the menu is the third state of the kind `editing` already was --\napp.js's window keydown returns early into shell.js::menuKey. Same mechanism, not\na new one, because the menu hangs over the grid and hjkl reaching through would\nscroll the thing it points at out from under it. menuKey answers EVERY key with\n`ignore` as the default (swallowed, never passed on), and count: 0 closes rather\nthan wrapping modulo zero.\n\nCODEX FOUND A REAL BUG and it was correct: the pageMenu branch originally sat\nABOVE app.js's metaKey guard, so with the menu open Cmd-R was answered `ignore`\nand then preventDefault'ed -- reload blocked -- and Ctrl-j/Alt-Home moved the\nmenu, two lines below a comment saying Ctrl/Alt stay the browser's. Fixed by\nordering plus one bail. VERIFIED BY THE ORCHESTRATOR on the merged branch: the\nmetaKey guard is above the branch, and pageMenuKeydown returns on\nctrlKey || altKey before claiming anything.\n\nBOUNDARY CROSSING, flagged and accepted: resolve.rs gained Click::PageItem and\nlib.rs a click_page_item. Unavoidable -- the ticket asks that choosing an item\nCOMPOSES SetPageSelection, the page holds no Basis, and design-principles\nsection 5 forbids it deriving one. No wire change: Command, ModelCommand and the\nframe pair are untouched. Indices, matching every existing Click variant, so the\npage never spells a category or item name.\n\nNOT VERIFIED: Firefox and WebKit run none of pages.spec.js (the config is\nChromium-only outside opfs/shell). The menu's position: fixed placement off\ngetBoundingClientRect is the part that could plausibly differ by engine.","status":"closed","priority":2,"issue_type":"task","owner":"el-github@elangley.org","created_at":"2026-09-22T06:07:10Z","created_by":"Edward Langley","updated_at":"2026-09-22T06:41:45Z","closed_at":"2026-09-22T06:41:45Z","close_reason":"Closed","labels":["browser"],"dependency_count":0,"dependent_count":0,"comment_count":0}
{"_type":"issue","id":"improvise-nn4s","title":"ADR 004: an Emacs-like face system, so a theme is UI-agnostic data the front ends apply","description":"USER DIRECTION 2026-09-22: \"I think we want to iterate towards having a way to\ntheme the app like emacs does: faces, etc. described in a UI-agnostic format that\nthe different frontends can apply (there's probably a swift version down the road\nand maybe Qt, etc.)\"\n\nNote \"iterate towards\". This is a DIRECTION, not a feature request, and the first\ndeliverable is an ADR (004 is free) rather than code.\n\nWHERE THE REPO ACTUALLY IS TODAY, measured:\n  - AxisColor { Row, Column, Page, Filter, Inactive } in improvise-core/view/axis.rs\n    -- names ROLES. This is the pattern working.\n  - MinibufColor { Green, Cyan, Yellow } in improvise-protocol/lib.rs -- names\n    COLOURS. draw.rs::minibuf_fg is an IDENTITY MAP (Green -\u003e Color::Green). Its\n    doc comment says \"semantic palette only\" and the type makes that false: there\n    is nothing to theme. The roles exist at the call sites (green is editing,\n    yellow is the prompt/destructive family, cyan is search) and were spelled as\n    colours.\n  - 124 `Color::` literals across 10 TUI files (draw.rs, grid.rs, every panel,\n    help, the wizard). No theme, palette or color_scheme concept anywhere.\n  - PR #120 just built a CSS custom-property palette for the browser. So the two\n    front ends are AT A FORK: either colour roles become shared vocabulary each\n    end maps to its own palette, or the web palette and the TUI's 124 literals\n    drift permanently and one document looks unrelated in two clients.\n\nSEVEN QUESTIONS THE ADR MUST ANSWER. They are listed because each is a place this\ngets decided by accident otherwise.\n\n1. THE TERMINAL-PALETTE TENSION, WHICH IS THE HARD ONE. A face's colour may want\n   to be \"the terminal's green\" rather than an RGB value. Today Color::Green means\n   whatever the USER'S TERMINAL calls green, so their terminal theme applies. A\n   format carrying only RGB would LOSE that -- a regression, not a gap, and one\n   that would be discovered late and be expensive to undo. Emacs answers it with\n   named colours plus tty approximation. Decide whether a face attribute can be\n   a NAMED terminal colour, an RGB value, or either, and what a browser does with\n   \"terminal green\".\n\n2. INHERITANCE is what makes a face system tractable rather than 124 entries.\n   Emacs derives most faces from a few. Decide whether faces inherit, and if so\n   whether the resolution happens in shared code (once, correctly) or per front\n   end (three times, differently).\n\n3. A THEME IS CLIENT-LOCAL. Gotcha 29 / the user's own ruling: the model is shared\n   and the UI is not. So a theme must NOT be a Command, must NOT live in\n   ViewState, and must NOT be projected -- otherwise one client's theme reaches\n   another client's screen, which is the exact bug improvise-g0f is about. State\n   this explicitly in the ADR; it is cheap now and a protocol change later.\n\n4. WHERE THE VOCABULARY LIVES. AxisColor is in improvise-core, which is supposed\n   to have no UI; MinibufColor is in improvise-protocol. That inconsistency\n   predates this and the ADR should resolve it rather than inherit it.\n\n5. WHICH ATTRIBUTES ARE PORTABLE. Foreground, background, weight, slant,\n   underline map onto ratatui Modifier, CSS, Swift and Qt. Box, shadow and\n   rounded corners do not reach a terminal. Decide the minimum common set, and\n   decide what a front end does with an attribute it cannot render -- Emacs\n   ignores it, which is probably right and should be SAID.\n\n6. THE FORMAT. A Swift or Qt front end means the theme is DATA, not Rust -- so it\n   needs a file format. TOML, JSON, or a small pest grammar in this repo's usual\n   style. It is NOT part of .improv: a theme is configuration, not document data,\n   and putting it there would make a document dictate a reader's colours.\n\n7. HOW IT ARRIVES WITHOUT A FLAG DAY. A big-bang refactor of 124 literals is how\n   this dies. The ADR needs a migration path where the vocabulary lands first and\n   the literals move opportunistically.\n\nTHE INCREMENTAL STEPS THAT FORECLOSE NOTHING, cheapest first:\n  a. Rename MinibufColor's variants to roles. Pure vocabulary, no behaviour, and\n     it converts \"semantic palette\" from a false doc comment into a true type.\n  b. Name PR #120's CSS custom properties after the same roles, so the web\n     palette is already a theme in the making rather than a second vocabulary.\n  c. Let the 124 literals migrate as files are touched for other reasons.\n\nNOT IN SCOPE YET: a theme picker, user-supplied theme files, or live reloading.\nThose follow the vocabulary; none of them is the hard part.","status":"in_progress","priority":2,"issue_type":"task","assignee":"agent-faces","owner":"el-github@elangley.org","created_at":"2026-09-22T05:44:55Z","created_by":"Edward Langley","updated_at":"2026-09-25T04:45:30Z","started_at":"2026-09-25T04:45:30Z","lease_expires_at":"2026-09-25T04:50:30Z","heartbeat_at":"2026-09-25T04:45:30Z","dependencies":[{"issue_id":"improvise-nn4s","depends_on_id":"improvise-gtn7","type":"parent-child","created_at":"2026-09-25T01:05:33Z","created_by":"Edward Langley","metadata":"{}"}],"dependency_count":0,"dependent_count":0,"comment_count":0}
{"_type":"issue","id":"improvise-oujb","title":"A release should carry the web app too: today a tag captures only the native binaries","description":"USER RULING 2026-09-22, asked whether the release workflow builds a package for the\nweb version and told it does not: \"Attach the site to releases too.\"\n\nWHAT IS TRUE TODAY. .github/workflows/release.yml has ZERO references to wasm, web,\npkg, pages or assemble -- verified by grep. It builds four native targets\n(aarch64/x86_64 x macOS/Linux) plus a shell installer, per dist-workspace.toml.\nThe web app ships by a completely separate route: ci.yml's pages-deploy, gated on\n`github.event_name == 'push' \u0026\u0026 github.ref == 'refs/heads/main'`. Continuous\ndeployment from the default branch, not a release artifact.\n\nFOUR CONSEQUENCES, none of them written down anywhere:\n  - A TAG DOES NOT DEPLOY THE SITE. pages-deploy fires only on a push to main, so\n    tagging leaves the site wherever main last was. Tag from main's tip and they\n    coincide BY ACCIDENT; tag an older commit and they diverge silently.\n  - There is no web version of a release to download, self-host or roll back to.\n  - THE PAGE NAMES NO VERSION AT ALL. web/assemble.sh stamps the cache-bust token\n    with $GITHUB_SHA, but nothing in web/index.html shows a version or commit, so\n    a visitor cannot tell what they are running and neither can a bug report.\n  - A binary user and a site user are running different code, potentially months\n    apart: v0.1.0-rc2's binaries are from 2026-04-11 and the site is from whatever\n    merged most recently. README's Installation section does not say so.\n\nTHE ASK: a tagged release also carries the assembled site as an artifact, so a\nrelease has a self-hostable web bundle and a rollback target.\n\nFIVE TRAPS, each of which is how this gets done wrong:\n\n1. release.yml IS AUTOGENERATED BY cargo-dist and says so on line 1. A hand edit\n   is clobbered by the next `dist init`. Use dist's own supported mechanism for\n   extra artifacts (see its `extra-artifacts` / custom build configuration in\n   dist-workspace.toml) so the addition SURVIVES REGENERATION. If no supported\n   mechanism fits, say so explicitly and argue for the hand edit rather than\n   making it silently -- and leave a comment in dist-workspace.toml so the next\n   `dist init` has a warning.\n2. DO NOT WRITE A SECOND WAY TO BUILD THE BUNDLE. ci.yml's `build` job carries a\n   long comment explaining that everything downstream DOWNLOADS from one\n   wasm-pack run precisely so \"the harness runs against the tree Pages publishes\"\n   is true by construction. A release job that builds its own bundle a different\n   way reintroduces exactly what that comment prevents. Use web/build.sh and\n   web/assemble.sh, the same scripts a developer runs.\n3. THE CACHE-BUST STAMP TAKES AN ARGUMENT AND THE RIGHT ONE DIFFERS. CI passes\n   $GITHUB_SHA; a local run defaults to `dev`. A release should almost certainly\n   pass the TAG. Decide, and note scripts/assemble-stamp.sh verifies each stamped\n   reference independently -- check it still passes with whatever you choose.\n4. THE RELEASE JOB NEEDS A TOOLCHAIN IT DOES NOT HAVE: wasm32-unknown-unknown,\n   a PINNED wasm-pack (ci.yml pins v0.15.0 and explains that pinning is what makes\n   a local measurement evidence about a CI run), and node for the prose site.\n   Reuse those pins rather than picking fresh ones.\n5. wasm-opt REJECTS LLVM's memory.copy WITHOUT --enable-bulk-memory, and the\n   worker bundle ALSO needs --enable-nontrapping-float-to-int because it carries\n   the whole App and so chrono's date arithmetic (gotcha 45). Those live in the\n   crates' Cargo.toml metadata; do not re-specify them.\n\nALSO IN SCOPE, because it is the cheap half of the same problem: GIVE THE PAGE A\nVISIBLE VERSION OR COMMIT. A site that cannot say what it is makes every bug\nreport about it unanswerable. Small, and worth more than the tarball.\n\nDECIDE AND STATE, do not default: whether tagging should ALSO deploy Pages, or\nwhether the site keeps tracking main and a release merely captures a copy. The\nuser chose \"attach the site to releases\", which does not by itself answer this.\nBoth are defensible; supporting both by accident is not.\n\nNOT IN SCOPE: bumping a version or cutting a tag (improvise-3tj / improvise-l36,\nboth need the user), and RELEASING.md, which improvise-gx5d owns on another branch.","notes":"USER RULING 2026-09-22, settling the open decision this ticket flagged: \"I like\nPages showing the latest main for now.\"\n\nSO: pages-deploy is UNCHANGED. It keeps its `github.event_name == 'push' \u0026\u0026\ngithub.ref == 'refs/heads/main'` gate; a tag does not deploy the site. A release\nmerely CAPTURES a copy of the assembled site as an artifact.\n\nNote the words \"for now\". This is a current preference, not a permanent\narchitecture decision, and whoever reads it later should be able to tell the\ndifference. Do not record it as settled forever.\n\nTHREE THINGS THAT FOLLOW, and they change the emphasis of the work:\n\n1. THE TWO LINEAGES DIVERGING IS NOW DELIBERATE, so it gets DOCUMENTED rather than\n   fixed. A binary user runs whatever was tagged; a site visitor runs latest main.\n   One sentence in README's Installation section.\n\n2. THE VERSION STAMP IS THE MOST VALUABLE PART OF THIS TICKET, not the tarball.\n   With the lineages deliberately different, a page that cannot say what it is\n   makes every bug report about it unanswerable. web/index.html names no version\n   at all today. If only one thing lands from this bead, it is the stamp.\n\n3. THE ARTIFACT'S PURPOSE IS NARROWER THAN IT SOUNDS. With Pages tracking main,\n   the release tarball is NOT what anyone visits -- it is a self-hostable copy and\n   a rollback target. Saying \"the web version of v0.1.0\" invites a reader to\n   assume the tarball is what is deployed, which is false and costs an afternoon.\n   State the narrow claim.\n\nThe cache-bust token question narrows too: since pages-deploy is untouched, the\nrelease capture is the only new caller of web/assemble.sh, so the tag is the\nobvious token.

So the workflow has run end to end and\nproduced everything it is supposed to produce.\n\nWHAT ACTUALLY HAPPENED: v0.1.0-rc3 was pushed to gh, origin and gitea while every\ncrate still said 0.1.0-rc2. dist matches the tag against the ROOT PACKAGE version\n(dist-workspace.toml says members = [\"cargo:.\"], so only the root package counts\nand gp-tree sitting at 0.1.0 is not a finding). It refused with \"This workspace\ndoesn't have anything for dist to Release!\" and named the right answer itself, and\nthe four jobs behind `plan` skipped.\n\nReproduced both directions locally: `dist plan --tag=v0.1.0-rc2` gets past the\ncheck; `--tag=v0.1.0-rc3` gives the CI error verbatim.\n\nA CORRECTION WORTH KEEPING, because it nearly became a false fact in context/: I\nfirst concluded rc1/rc2 had never triggered the workflow, inferring it from an\nempty `gh run list`. GitHub Actions logs AGE OUT AT 90 DAYS and those tags are\nfive months old.

Verified by the orchestrator while\nscoping the ruling:\n\n  - ModelCommand::LoadModel(PathBuf) is ON THE WIRE (protocol/src/reduce.rs:159).\n  - effect::LoadModel (command/src/ui/effect.rs:914) calls\n    persistence::load_from(\u0026*app.storage, \u0026self.0) with the CLIENT'S path.\n  - PhysicalFs (io/src/storage.rs:94) has NO root and NO confinement:\n    File::open(path) and File::create(path) on whatever arrives.\n  - improvise-ws-server builds its App with App::new(workbook, path), which\n    supplies that unconfined PhysicalFs.\n\nSo ANY CONNECTED WEBSOCKET CLIENT CAN ASK THE HOST TO READ ANY FILE THE SERVER\nPROCESS CAN READ. A .improv-shaped file loads wholesale and is then projected\nback to the client. A file that does NOT parse is still a leak risk: the error\ngoes into view_state.status_msg as \"Load error: {e}\", and pest errors quote the\noffending input.\n\nWRITE IS NOT YET CLIENT-REACHABLE -- Save/SaveAs are ViewOnly and off the wire --\nBUT IT IS ABOUT TO BE. improvise-y11g (the : command line, a core feature per the\nuser) reaches `:w \u003cpath\u003e`, and improvise-2mqz adds the export/download frames.\nLanding either without this is how arbitrary file WRITE ships.\n\nPAIR WITH improvise-kc7n: the Origin check answers what PAGE is driving a client,\nnever WHO is connecting, and improvise-kpnr (authentication) is open. Confinement\nis the control that does not depend on either.\n\nWHERE IT BELONGS: THE BACKEND, NOT THE CALL SITES. Gotcha 2 -- every document read\nor write goes through App::storage, and the host picks the backend. So this is a\nROOTED PhysicalFs (e.g. PhysicalFs::rooted(dir)), and every caller is covered by\nconstruction rather than by each remembering to check. That is\ndoctrine(an_invariant_is_made_unrepresentable_not_validated), the same answer\nprune_axis_items and gp-tree's Row\u003cT\u003e got.\n\nCRITICALLY, THIS IS A PROPERTY OF THE SERVER, NOT OF Storage. A TUI user may open\nany file they own; confining App::new would be WRONG. The server constructs the\nrooted backend; the TUI keeps the unrooted one. Gotcha 2 already says the host\npicks, so this fits without a trait change.\n\nSIX IMPLEMENTATION TRAPS, each of which is the standard way this fix is got wrong:\n\n1. std::fs::canonicalize REQUIRES THE PATH TO EXIST. A write to a NEW document\n   fails it. Canonicalize the PARENT and join the final component -- and reject a\n   final component that is itself `..` or contains a separator.\n2. REJECT, DO NOT SANITIZE. Stripping or collapsing `..` is the classic broken\n   fix; `....//` and percent/unicode variants defeat it. Canonicalize, then\n   compare.\n3. COMPARE COMPONENT-WISE, NOT AS STRINGS. `/srv/docs-evil`.starts_with(\"/srv/docs\")\n   is TRUE as a string and false as a path. Use Path::starts_with, which is\n   component-wise, and canonicalize the ROOT once at construction (a relative or\n   symlinked root defeats the comparison otherwise).\n4. SYMLINKS: canonicalize resolves them, so a link inside the directory pointing\n   out IS caught -- but only because the check runs on the resolved path. Do not\n   \"optimise\" it into a lexical normalisation.\n5. TOCTOU IS A STATED RESIDUAL, NOT A SOLVED PROBLEM. Between the check and the\n   open, a component can be replaced. openat2(RESOLVE_BENEATH) is the real answer\n   and portable Rust does not have it. The user has ruled that containerization\n   carries this; SAY SO in the code's context/ prose rather than implying the\n   check is total.\n6.

Decide and state whether the\nexisting multi-file form survives as \"these files, which must be under the root\"\nor is replaced by \"this directory\". Both are defensible; silently supporting both\nis not.\n\nTESTS -- and the check_the_checker discipline applies, because a confinement test\nthat passes against an unconfined backend is worse than none:\n  - ../ escapes, absolute escapes, a symlink inside the root pointing out, a root\n    that is itself a symlink, and the `/srv/docs-evil` string-prefix case.\n  - A NEW file inside the root must be WRITABLE -- the case trap 1 breaks.\n  - Drive it through ModelCommand::LoadModel over Sessions, not just against\n    PhysicalFs directly: the vulnerability is reachable from the wire and the test\n    should be too.\n  - INJECT THE FAULT: point the rooted backend's root at `/` and watch the escape\n    tests fail. A confinement test that cannot fail is the characteristic defect\n    of this repo.\n  - Consider whether io/src/storage.rs::contract::storage_contract should gain a\n    confinement clause.

It is filed now as a VERIFY-FIRST ticket, because the obvious\ndiagnosis is wrong and the real cause may already be fixed.\n\nWHY IT IS NOT A PAINTING BUG. web/app.js (:247-251) paints the minibuffer, and\nrender.rs::every_minibuffer_mode_paints_what_is_being_typed asserts all four\ntext-entry modes paint their prompt and the typed value. That test exists because\npainting WAS the bug once (improvise-fdt6, evidence in\ncontext/test-evidence/clients.md) and it was fixed.\n\nWHY THE TEST CANNOT SEE THE REPORTED SYMPTOM, which is the interesting part: it\nfolds Command::ChangeMode(mode) DIRECTLY. It never presses a key. So it proves the\npaint works GIVEN the mode, and says nothing about whether a keypress can REACH the\nmode. That is this repo's characteristic defect -- a test that passes while the\nthing it names is broken -- sitting in the exact place the symptom points.\n\nSO THE HYPOTHESIS TO TEST IS REACHABILITY, not rendering: does a browser keypress\nactually put the client into AppMode::CategoryAdd? resolve.rs::stranding() refuses\nonly SavePrompt, ExportPrompt and CommandMode, so category-add is not stranded --\nbut `search-or-category-add` sat on the_command_names_that_still_need_the_host_are_these\nuntil PR #114 moved it off (improvise-koh6).

Verify against current main FIRST and close on evidence\nif so -- do not build anything before reproducing.\n\nIF IT REPRODUCES: the fix is whatever makes the key reach the mode, and the test\nthat earns its place is one that goes from a KEYPRESS to a painted minibuffer, not\nfrom a folded ChangeMode.

Both are Commands. Composable in one\n   line; the cheapest single win in the audit.\n\n   BUT IT MUST NOT SHIP ALONE. search-navigate scans the model for matching cells and\n   the client has only a viewport-windowed GridCache, so it is NOT composable --\n   shipping `/` without `n` gives a browser user a search box that finds nothing,\n   which is a WORSE failure than the current silence.

So the guard works; its reach is the defect.\n\nCONSEQUENCE: a command name bound only under g/y/Z, or on a function key, can be unregistered -- OR have args that will not parse, since improvise-s13 moved enter-mode into the args-carrying class -- and the whole suite stays green. That is the exact failure the guard was written for, surviving in the region it does not reach.\n\ndump_every_binding DOES descend into prefixes via which_key, but it is a DUMP gated on IMPROVISE_BINDING_DUMP, not an assertion -- inert in CI, so it does not cover the gap.\n\nTHE CONTRAST THAT MAKES THIS WORTH FIXING RATHER THAN NOTING: nothing_declined_is_also_composed in improvise-protocol/src/resolve.rs is the STRONGER guard -- its bound_commands helper DOES recurse into Binding::Prefix and into parents. So the resolution side is guarded where the registration side is not, and an agent reading either test alone would reasonably conclude its bindings are checked. Only comparing the two shows which half is real.\n\nFIX SHAPE: descend into Binding::Prefix in the walk, and make probe_keys cover what probe_keys_pub already does. Both are small. The acceptance is the injection above failing -- test it with a name behind a prefix AND one on an F-key, because they are two different blind spots and one fix may not close both.\n\nRelevant: gotcha 13 (prefixes are stored as an address; KeymapSet::prefix_keymap walks parents so RecordsNormal reaches Normal's g/y/Z) and gotcha 15 (the guard checks BOTH halves of dispatch -- the name resolves and the args parse).\n","status":"closed","priority":2,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-22T00:49:14Z","created_by":"Edward Langley","updated_at":"2026-09-22T02:27:16Z","closed_at":"2026-09-22T02:27:16Z","close_reason":"Fixed in PR #112 (wave/q-keymap, head b4bd6bc), both blind spots closed and each injection fails SEPARATELY -- which was the acceptance, because a fix for one need not close the other.\n\n - PREFIX: reachable_names now recurses into Binding::Prefix.

Read indices off data- attributes\n(data-row/data-col on a cell, data-index on a row or tile) with\nevent.target.closest(..).\n\nFOUR THINGS A NAIVE REWRITE BREAKS. All are documented and load-bearing:\n\n1. THE GRID USES mousedown, NOT click, DELIBERATELY (improvise-0x9u). From an\n   editing state the input's blur repaints first, so the \u003ctd\u003e is gone before a\n   click could fire. Delegation does not change that -- the target is detached\n   before the event -- so it must stay mousedown.\n\n2. IT CALLS preventDefault(). Dropping that reintroduces focus/selection\n   behaviour the editor depends on.\n\n3. IT CONDITIONALLY SKIPS THE REPAINT. On an editable cell it calls edit(..) and\n   does NOT repaint, because a repaint would take the \u003cinput\u003e away. The comment\n   at :356-360 says so. A delegated handler must keep that branch.\n\n4. IT CLOSES A LIVE EDITOR FIRST (`if (editing) editing.close(false)`), before\n   composing the click. Order matters.\n\nTHE EDITOR'S OWN TWO LISTENERS (keydown, blur at :414/:424) are a different\ncase: one transient node, one at a time, attached at creation and gone with it.\nDelegating those buys nothing and would need the blur/keydown to find the input\nthrough a root that does not own it. Leave them direct unless there is a reason;\nsay so in the change rather than silently keeping them.\n\nWHY THIS IS NOT PRIMARILY A PERFORMANCE TICKET, and should not be argued as one:\nthe cell count is bounded by the VIEWPORT, not the document -- set_viewport\nannounces a real window and GridCache is viewport-indexed for the browser\n(gotcha 47) -- so it is a few hundred closures per repaint, not thousands. And\nit does not leak: replaceChildren drops the nodes and their listeners with them.\nimprovise-i5tk's rule applies -- do not claim a performance win without a\nbenchmark, and \"it is fine\" is exactly as unevidenced as \"this dominates\".\n\nThe real argument is the repo's own: design-principles section 5 wants web/app.js to\ntrend to \"paint and wire\", and one handler per surface is wire where one handler\nper node is bookkeeping that grows with the data.\n\nTESTING: a change to web/*.js belongs in harness/tests/shell.spec.js (gotcha 48),\nnot a new ad-hoc surface. The assertions that matter are the four above, each of\nwhich is a behaviour a rewrite can silently lose: a click from an OPEN EDITOR\nstill lands (that is 0x9u's own case), the editor is not taken away when opening\none, and a click on the panel/tile surfaces still dispatches after a repaint.\nPure decision logic (target -\u003e indices) can go in web/shell.js, which is\nnode --test-able with no DOM.\n","notes":"USER LATITUDE 2026-09-21: \"We can use IDs, classes or data attributes as necessary to disambiguate the action to be taken.\"\n\nThe mechanism is open.

{"_type":"issue","id":"improvise-636d","title":"Introduce a global keymap that almost all modes inherit from","description":"User ask, 2026-09-21: confirm keymap inheritance works and the keymaps are\nactually shared, and put `?` in a base keymap overridden only in insert mode.\n\nVERIFIED at 523d571. Three findings, and the first is good news.\n\n## 1. THE KEYMAPS ARE GENUINELY SHARED. No drift is possible.\n\n  browser: resolve.rs:53  Keymaps::shared().lookup(..)\n  TUI:     improvise-command/src/command/keymap.rs:127  Keymaps::default_keymaps()\n\nDifferent constructors, but `shared()` (keymap.rs:446) is a OnceLock over\n`default_keymaps` itself:\n\n    static KEYMAPS: OnceLock\u003cKeymaps\u003e = OnceLock::new();\n    KEYMAPS.get_or_init(Keymaps::default_keymaps)\n\nSo there is ONE definition and two callers -- a cached copy and a fresh one of\nthe same function. Content is identical by construction, not by a test holding\ntwo copies in step. This is the shape design-principles section 5 asks for and it\nis already right.\n\n## 2. INHERITANCE WORKS AND IS USED TWICE IN SEVENTEEN MODES.\n\nThe mechanism is real -- Keymap::with_parent, and lookup() walks parents. But\n`with_parent` is called at exactly two sites:\n\n    keymap.rs:656   RecordsNormal  inherits Normal\n    keymap.rs:834   RecordsEditing inherits Editing   (via TextEntry::with_parent)\n\nEvery other mode is a ROOT keymap. PanelKeymap::new and TextEntry::new both\nbuild with Keymap::new(), so the three panel modes, TileSelect, SearchMode,\nHelp, ImportWizard and the seven other text-entry modes inherit from nothing.\n\nThere is no base keymap. What looks like sharing across modes is actually\nSPINES -- PanelKeymap::new and TextEntry::new each re-bind a common set into a\nfresh map. That is duplication-by-builder rather than inheritance: correct\ntoday, and nothing makes it stay correct.\n\n## 3. `?` RESOLVES IN 2 OF 17 MODES.\n\nIt is bound once, keymap.rs:551, on `normal`:\n\n    normal.bind_args(KeyCode::Char('?'), none, \"enter-mode\", vec![\"help\"])\n\nSo it works in Normal and -- via the one inheritance edge -- RecordsNormal.\nIt does NOT resolve in: CategoryPanel, FormulaPanel, ViewPanel, TileSelect,\nSearchMode, ImportWizard, or Help itself. Those are exactly the modes a user is\nmost likely to be lost in.\n\nIt correctly does not resolve in the eight text-entry modes, where `?` must type\na literal `?`.\n\n## THE PROPOSED FIX IS FREE, and this is the load-bearing detail\n\nPut `?` in a base keymap and let every non-insert mode inherit it. **Text-entry\nmodes need NO explicit override**, because of the existing lookup order:\n\n    lookup_local:  exact(key,mods) -\u003e Char(NONE) -\u003e AnyChar -\u003e Any\n    lookup:        lookup_local(..) THEN parent\n\n`lookup_local` is exhausted BEFORE the parent is consulted (keymap.rs:261-264).\nSo a text-entry child's own `AnyChar` -\u003e append-char shadows a parent's exact\n`?` automatically. The override the user asked for already falls out of the\nfallback order; it does not have to be written.\n\n## WHAT TO DECIDE WHILE DOING IT\n\n - Which keys belong in the base besides `?`. `:` (command mode) is already\n   re-bound by both PanelKeymap::new and normal, and is a candidate. Do not\n   sweep everything in: a base keymap that binds too much makes every mode's\n   keys harder to reason about, which is the opposite of the ask.\n - Whether `?` in Help CLOSES the overlay. Today Help has no `?` at all. Toggling\n   is the obvious reading and is not what the current binding does anywhere.\n - Whether the panel spines should BECOME inheritance rather than re-binding.\n   That is the larger change and can follow; it is what would stop the\n   duplication from drifting.\n\n## GUARD TO ADD\n\nThere is no test that a key resolves in every mode that should have it.\n`every_hint_key_resolves_in_its_mode` checks each mode's HINT against its own\nmap, which cannot see a key that no hint mentions. `prefix_keymaps_are_flat`\nand `every_bound_command_name_is_registered` are the other two and neither\ncovers this. So the acceptance is a test naming the base keys and asserting they\nresolve in every non-text-entry ModeKey -- and, in the other direction, that\nthey resolve to append-char in the text-entry ones.\n\nRelated: improvise-uln5 records that the help OVERLAY advertises eight keys that\ndo nothing in the browser. `?` being unreachable from most modes is the other\nhalf of the same complaint -- the help is hard to reach and then wrong.\n","notes":"USER RULING 2026-09-21: 'Almost all the command modes should inherit from a global mode.'\n\nThat supersedes this bead's original framing. It is no longer 'put ? in a base\nkeymap' -- ? is one symptom. The work is the global keymap itself, and the panel\nand text-entry SPINES become inheritance rather than re-binding.\n\nWHAT IS DUPLICATED TODAY, which is the concrete scope:\n\n  bind_panel_toggles(\u0026mut km)  is called TWICE -- keymap.rs:367 (PanelKeymap::new)\n  and :555 (normal). It binds one toggle-panel-and-focus per Panel::ALL. So the\n  panel toggles are already written once and APPLIED twice into two roots; that\n  is the duplication-by-builder this ruling removes.\n\n  ':' -\u003e enter-mode command   bound in PanelKeymap::new (:369) and again in normal.\n  '?' -\u003e enter-mode help      bound ONLY in normal (:551). The asymmetry between\n  these two is itself evidence nothing is keeping the spines in agreement.\n\nWHY THIS IS SAFE FOR 'ALMOST ALL' RATHER THAN NEEDING EXCEPTIONS -- the existing\nfallback order does the work:\n\n    lookup_local:  exact(key,mods) -\u003e Char(NONE) -\u003e AnyChar -\u003e Any\n    lookup:        lookup_local(..) THEN parent      (keymap.rs:261-264)\n\nLocal is exhausted BEFORE the parent. Two consequences that make the ruling\ncheap:\n - a TEXT-ENTRY mode inheriting the global still types a literal '?', because its\n   own AnyChar -\u003e append-char is found locally first. No override needed.\n - IMPORT WIZARD binds KeyPattern::Any, which catches everything locally, so it\n   inherits harmlessly -- nothing ever reaches the parent.\n\nSo the modes that must NOT inherit are those where a global key would be actively\nwrong AND is not already shadowed. Name them explicitly rather than assuming;\nthe honest answer may be 'none', which would make it 'all' rather than 'almost\nall' and is worth saying out loud if so.\n\nWHAT STILL NEEDS DECIDING, and these are the product calls:\n - Which keys are global. '?' and ':' and the panel toggles are the candidates\n   the duplication already nominates. Resist sweeping more in: a global that\n   binds too much makes every mode harder to reason about, which is the opposite\n   of the ask.\n - Whether '?' in Help CLOSES the overlay. Today Help binds no '?' at all.\n - Esc is NOT a candidate: it means something different in nearly every mode.\n\nGUARDS THE CHANGE OWES. There is no test that a key resolves in every mode that\nshould have it -- every_hint_key_resolves_in_its_mode checks a mode's hint\nagainst its own map and cannot see a key no hint mentions. So:\n - every global key resolves in every mode that inherits the global\n - in the eight text-entry modes it resolves to append-char instead\n - bind_panel_toggles has ONE call site afterwards, which is the mechanical\n   check that the duplication is actually gone\n\nNote gotcha 13: prefix keys are stored as an ADDRESS and resolved via\nKeymaps::prefix_keymap, which walks parents -- so RecordsNormal already reaches\nNormal's g/y/Z that way. prefix_keymaps_are_flat must still pass; a global\nkeymap must not introduce a nested prefix.\n\nThe good news from the original investigation stands and is not affected: the\nkeymaps are genuinely SHARED between the two front ends. Keymaps::shared() is a\nOnceLock over default_keymaps itself, so there is one definition and two callers,\nnot two copies held in step by a test.","status":"open","priority":2,"issue_type":"task","owner":"el-github@elangley.org","created_at":"2026-09-22T00:33:38Z","created_by":"Edward Langley","updated_at":"2026-09-22T00:33:55Z","labels":["protocol","ux"],"dependencies":[{"issue_id":"improvise-636d","depends_on_id":"improvise-gtn7","type":"parent-child","created_at":"2026-09-25T01:05:32Z","created_by":"Edward Langley","metadata":"{}"}],"dependency_count":0,"dependent_count":0,"comment_count":0}

Every other click surface in\n   this panel has an inverse -- a Category row calls toggle_cat_expand_at -- so\n   the one gesture that changes the DOCUMENT is the one with no way back.\n\n2. IT SILENTLY DESTROYS THE CATEGORY'S PREVIOUS AXIS. SetAxis overwrites Row,\n   Column or None with Page and nothing records what it was. So even a future\n   \"clear\" cannot restore the prior layout; the best it could do is guess None.\n   The status line says \"Filter: ...\" while what actually happened is a LAYOUT\n   change, which is also why it reads as undoable when it is not.\n\n3. THE ESCAPE ROUTE EXISTS AND IS UNDISCOVERABLE. click_tile (resolve.rs:148)\n   cycles a tile's axis on a SECOND click of an already-selected tile, so\n   Page -\u003e None is reachable by clicking the category's tile twice. But:\n     - nothing says so, and the status line points at \"Filter\", not the tile bar\n     - it cycles Row-\u003eColumn-\u003ePage-\u003eNone, so \"clear\" is up to three more clicks\n     - the TUI's other route, [ and ] page cycling, has no browser affordance:\n       improvise-p7lh records that the browser draws NO PAGE BAR at all, and\n       GridCache::page_coords does not reach RenderModel\n\nSo the feature is reachable in principle and absent in practice, which is worse\nthan absent -- the user concludes it cannot be done.\n\nWHAT A FIX HAS TO DECIDE, and it is a product call rather than a bug:\n - Should a second click on the SAME item clear the filter? That makes the\n   gesture reversible and is what \"filter\" implies. It also needs an answer for\n   what axis the category returns to, given (2) destroyed it.\n - Or should clicking never move a category to Page at all, and instead set a\n   page SELECTION only when the category is already on Page, leaving the\n   layout alone? That is the smaller, more honest gesture and it makes (2)\n   moot -- but it changes what the click does for every category not already\n   paged.\n - Either way the page bar wants painting (improvise-p7lh), because that is\n   where a paged category is visible and cyclable in the TUI, and its absence\n   is what makes the state feel trapped.\n\nNote gotcha 27: Page and Filter are different axes, and only Page is navigable.\nThis code uses Page, correctly -- but the STATUS LINE calls it a filter, which\nis the vocabulary of the non-navigable one. Worth aligning whichever way the\nproduct call goes.\n","notes":"MECHANISM CORRECTED 2026-09-21 by driving it under Chromium. My original code-read was right about the click path and WRONG about the way out, and the real defect is one neither the report nor I named.\n\nCONFIRMED: filter_to_item_at emitting SetAxis{Page} + SetPageSelection + the status is correct. Clicking an item gives 'Filter: Product = Espresso', the tile goes Row -\u003e Pag, the grid collapses 4 rows to 1. A SECOND click on the same item is a genuine no-op -- not a toggle. Clicking a DIFFERENT item switches the filter, so you can move a filter but not lift it.\n\nWRONG IN MY READ: the tile-bar double-click is NOT the only way back, and the tile bar IS visible and clickable in the shipped page (#tiles .tile, five of them). There is a second, KEYBOARD route: Space in the category panel (cycle-axis-at-cursor), which is advertised in that mode's own hint as 'Space:cycle-axis' and works directly after the click with no re-focus. So the escape is more discoverable than I claimed.\n\nTHE ACTUAL DEFECT: NEITHER ROUTE CLEARS ANYTHING. They only hide the filter, and it comes back. Measured, cycling Product all the way round:\n\n    Pag(Espresso) -\u003e None (63,700, unfiltered)\n                  -\u003e Row  (all 4 products)\n                  -\u003e Col\n                  -\u003e Page -\u003e 18,400   \u003c- Espresso is BACK, unasked\n\nView::set_axis (improvise-core/src/view/types.rs:118) does NOT touch\npage_selections. Only on_category_removed and on_item_removed ever clear one. So\nthe selection survives every axis move and is silently reinstated the moment the\ncategory returns to Page.\n\nThere is NO ClearPageSelection anywhere -- not in ModelCommand, not in the View\nAPI, AND NOT IN THE TUI. So this is a product gap at parity, not a browser\nregression. The browser is simply the first place anyone tried it with a mouse.\n\n[ and ] cannot clear it either: measured, they cycle the page selection among the\ncategory's items (18,400 -\u003e 17,100 -\u003e 15,800 -\u003e 20,300 -\u003e 24,600) with no 'All'\nentry to land on.\n\nTHIRD FINDING, and it may be what produced the original report: THE STATUS LINE\nLIES. 'Filter: Product = Espresso' stays on screen after the axis has gone to\nNone, Row and Col, and after five ] presses moved the page to a different item.\nThe one piece of feedback about the filter is stale exactly while the user is\ntrying to get rid of it -- so a user who DID clear it correctly is told for the\nrest of the session that it is still on. That mechanism can manufacture this\nexact bug report from a working code path.\n\nSilent-Space is split out as improvise-25bf.","status":"closed","priority":2,"issue_type":"bug","assignee":"agent-refuse-fu","owner":"el-github@elangley.org","created_at":"2026-09-22T00:17:00Z","created_by":"Edward Langley","updated_at":"2026-09-23T15:02:18Z","started_at":"2026-09-23T15:00:20Z","closed_at":"2026-09-23T15:02:18Z","close_reason":"Already fixed by 7a446166 (PR #114): View::set_axis forgets the page selection when a category leaves Page/Filter.

What is lost is the case where the\nuser wants neither -- a wide numeric category left alone while the fit uses the\nmeasures.\n\n## Steps to Reproduce\n\nBuild a model with a Regular category `Year` holding 100 numeric items\n(1900..1999), a Label category for record identity, and two measures `Cost` and\n`Score` where Score = 4000 if Cost \u003e 50 else 1000.

The fixture is\n`wide_category_beside_a_good_measure()` in crates/improvise-gp/src/fit.rs.\n\n## Acceptance Criteria\n\nThe honest fix is a budget that can decline A COLUMN rather than the whole\ntable: `encoded_width` (and the exact check beside it) would drop the widest\ncategory and report it as a `Dataset::warnings` notice -- gotcha 37(a), it comes\nback as DATA and nothing prints. That keeps the zv8t decision intact (a category\nis still never inferred numeric) and changes only what the budget does when it\ncannot afford one.\n\nDo NOT close this by making the forcing conditional on cardinality: that is\ninference by another name, and makes the ENCODING depend on a budget rather than\non what the document says.\n","notes":"=== TRACKER DEFECT, RECORDED BEFORE THE CLOSE ===\nTHIS TICKET'S STORED DESCRIPTION IS VERBATIM improvise-e8no'S BODY (the wide-\nnumeric-category budget) and contradicts its own title.

TWO DISTINCT OVERFLOWS, and this ticket names only the\nfirst:\n  1. THE MULTIPLY. A lone importance above f32::MAX/100 ~ 3.4e36 makes\n     100.0 * 3e37 = inf before the divide that would have returned it to range.\n  2. THE SUM -- THE SILENT TWIN, and it is real. Two importances at 2e38 are each\n     well inside f32, but their f32 TOTAL is inf, so every share came back NaN.\n     No panic, no refusal, just NaN% in the report. Exactly cv_regress's shape\n     from improvise-pv3g.\n\nREACHABLE PAST pv3g, traced rather than guessed: both callers score importance in\nthe document's OWN units (fit_csv -\u003e real_unit_mse; fit_measure -\u003e mse over\nUNNORMALIZED rows), so an importance is an MSE difference and grows as the\ntarget's SQUARE. That leaves a live window between pv3g's standardize refusal\n(spread ~5e18 at 12 rows) and this overflow (~1.8e18). As with pv3g, every INPUT\nwas finite and the overflow was in the DERIVED quantity.\n\nTHE FIX makes the arithmetic incapable of it rather than checking afterwards: sum\nand ratio in f64, narrowing only the share, which is bounded by 100 and therefore\nalways finite. One guard remains for an importance that ARRIVES non-finite -- note\nNaN \u003c= 0.0 is false, so the pre-existing early return passed NaN straight through.\n\nTHE RIVAL IS THIS TICKET'S OWN TITLE. Reassociating to 100.0 * (imp[j] / total)\nin f32 -- \"multiplies first\", so divide first -- passes the lone-importance test\nAND the shares-sum-to-100 test, and FAILS the twin and the non-finite guard:\n58 passed, 2 failed. It converts NaN% into a serene 0% FOR EVERY FEATURE, which is\nworse for being readable. THE AC AS WRITTEN WOULD HAVE SHIPPED A HALF-FIX.\n\nAND THE REASON IT SAT OPEN IS THE BEST PART. context/code/gp.md section 7 --\npv3g's own write-up -- did not merely mention this bug, it DEFERRED IT ON A COST\nTHAT IS FALSE: \"reordering it moves the bit patterns\nmisclass_rate_and_importance_are_bit_for_bit_what_they_were pins\". That test pins\npermutation_importance's RAW SCORES, which importance_ranking consumes afterwards.\nVERIFIED BY THE ORCHESTRATOR: scoring_known_answers.rs is absent from the diff\nentirely -- byte-identical across the fix. A cost predicted from a test's NAME\nrather than from what it CALLS is how a one-line fix stays filed, and it reads as\ndiligence, which is why it survives review. Corrected in place rather than\ndeleted.\n\nThe tell was visible all along: pv3g's own\nthe_cli_does_not_abort_when_an_importance_share_overflows says IN ITS NAME that a\nshare overflows at 1e18. The clamp stopped the abort; the inf% it was clamping\nnever stopped.\n\nNOT VERIFIED: the f64 round-trip is not bit-pinned for the ORDINARY range.\nimportance_ranking's shares have never been pinned and this did not start; a \u003c=1\nulp shift in a printed {:\u003e5.1}% is possible in principle and nothing would catch\nit.

Verified by the orchestrator.\n\nThe spelling that reaches the second workspace root:\n\n    cargo fmt --manifest-path harness/opfs-contract/Cargo.toml -- --check   # exit 0\n\nWHY THIS MATTERS MORE THAN A TYPO: an earlier agent reported this gate as\n\"clean\" during the wave's integration review. Either it used a different\nspelling and did not say so, or it read exit 1 as a pass -- and neither is\ndistinguishable from the report as written. A gate whose failure mode looks\nexactly like the thing it checks for will eventually be \"fixed\" by deleting it,\nand in the meantime it launders a non-run into a pass.\n\nThis is the same family as the pipe-into-tail trap that scripts/pr-reviews\ncarries a warning about: `$?` belonging to something other than the thing you\nmeant to test.\n\nWHERE THE RECIPE NEEDS CORRECTING: wherever the harness gate is written down --\nAGENTS.md's gate list, the wave brief template, and any CI step that spells it\nthis way. CI itself uses `cargo fmt -p opfs-contract` from INSIDE\nharness/opfs-contract, where it resolves, which is why CI has been right while\nevery local invocation of the documented form was not.\n\nCONTEXT: harness/opfs-contract carries its own [workspace] table, so\n`cargo fmt --all` does not reach it. Exactly two workspace roots exist --\n`grep -l '^\\[workspace\\]' $(find . -name Cargo.toml -not -path '*/target/*')` --\nso one extra gate is complete, not the first of an unknown number.\n","notes":"SHARPENED 2026-09-21: the boundary is POSITIONAL, and that changes who is at fault.\n\n  cargo fmt -p opfs-contract -- --check   from the REPO ROOT      -\u003e exit 1, 'not a member of the workspace', --check never runs\n  cargo fmt -p opfs-contract -- --check   from INSIDE the crate   -\u003e exit 0, works\n  cargo fmt --manifest-path harness/opfs-contract/Cargo.toml -- --check   from the root -\u003e exit 0, works\n\nSo CI AS WRITTEN IS CORRECT -- its working-directory: is exactly what makes the -p form resolve. The hazard is a BRIEF or a local pre-push habit telling someone to run it from the root, which is what the orchestrator did in six wave briefs.\n\nThe failure mode is worse than 'wrong spelling' in both directions: from the root the gate reports FAILURE when the crate is clean, and it cannot report SUCCESS when the crate is dirty. It is decoupled from the thing it checks entirely, while wearing the exit code of a real formatting failure.\n\nThis also explains a discrepancy in the wave's records: one agent reported this gate 'clean' and the orchestrator later measured exit 1. Both were telling the truth -- that agent had cd'd into the crate directory and never saw the error. A gate whose result depends on the working directory, with no indication in the output which one it ran in, cannot be audited from a report.\n\nFIX: correct the recipe wherever it is written for humans or agents (AGENTS.md gate list, the wave brief template).

An\n   async fn in Effect::apply is a DIFFERENT TRAIT, and it reaches the native TUI\n   too. Load-bearing, not plumbing.\n   NARROWER VARIANT worth costing first: keep Storage sync over an IN-MEMORY\n   document, flushed asynchronously from the message loop -- the shape\n   commit_deletes() already has. Storage never becomes async; a fifth awaited\n   method persist() joins the four. UNCOSTED: what holds a document in memory\n   across a LoadModel, and what a crashed tab loses that a sync handle would not.\n\nB. Nested dedicated worker under a SharedWorker. DEAD. Firefox allows it and the\n   nested worker gets a real working sync handle with OpfsFs unchanged; Chromium\n   and WebKit do not implement nested workers in shared workers at all\n   (\"ReferenceError: Worker is not defined\"). The one shape that would have cost\n   nothing works in exactly one engine.\n\nC. Keep the dedicated worker, add a RELAY owning no storage -- a SharedWorker or\n   BroadcastChannel moving ClientFrame/ServerFrame JSON between follower tabs and\n   the one tab whose dedicated worker holds the handle.\n   improvise_protocol::frame is already THE one pair for all deployments\n   (improvise-xks6), and the argument recorded there is explicitly\n   transport-agnostic. A third transport is the case that consolidation was made\n   for.\n    - probably free: Worker::on_frame's \"one client by construction\". Gotcha 45\n      already says the Addressed filter is honoured against a future SharedWorker.\n      Session ids, fan-out and per-session mirrors need nothing new.\n    - LOAD-BEARING: leader election and failover. The handle IS released when the\n      leading tab closes, but bindings.rs::boot has NO RETRY PATH, so a follower\n      cannot be promoted without a reload -- the same \"dead until you reload\"\n      through a different door.\n    - LOAD-BEARING: the relay must serialize frames onto one tail promise.\n      web/worker.js had this exact race and web/serial.js exists because of it\n      (gotcha 48). A relay forwarding async reintroduces it ACROSS TABS, where\n      gotcha 33 answers an overtaken update by DROPPING it.\n    - REVISIT: persist-on-dirty. Storage is whole-document (gotcha 41), so N\n      editing tabs is N whole-file rewrites through one handle.\n\nRECOMMENDED ORDER (agent's read, not a ruling): C first, A's narrow variant\nsecond, read-only as the fallback it now is. C's real price -- leader failover --\nis THE SAME MISSING RETRY PATH the read-only fallback needs anyway, so that work\nis not wasted either way.\n\nDO NOT treat this as small because Sessions is ready. That readiness is real and\nis the good news; the no is entirely on the storage side.\n\nUNTESTED: Safari proper. Playwright's WebKit has no OPFS in any context so it is\nunaskable here. Safari 17+ ships OPFS; whether createSyncAccessHandle is\ndedicated-only there too is an EXPECTATION, not a measurement.\nUNPROBED: whether BroadcastChannel beats a SharedWorker relay for C.

Tab in Normal is \"cycle-panel-focus\", which is meaningless unless panels\n     stay open while unfocused.\n  3. The panel hint spells \"enter-mode normal\" as \"back\", not \"close\".\n\nEverything else in the note above stands, in particular the launch-state\nargument: category_panel_open starts TRUE while the mode is Normal, so an open\npanel in Normal is the state the app boots in -- if that were the bug, the app\nwould boot in the bug.","status":"closed","priority":2,"issue_type":"bug","assignee":"agent-refuse-fu","created_at":"2026-09-21T20:32:39Z","created_by":"box","updated_at":"2026-09-23T15:12:27Z","started_at":"2026-09-23T15:00:18Z","closed_at":"2026-09-23T15:12:27Z","close_reason":"USER RULING 2026-09-23: keep as is.

The documented syntax is wrong, on the product's own quick-start page, for the headline feature.\n2. The refusal NAMES A COMMAND THE USER DID NOT TYPE — they typed `formula`, the message says `add-formula`. The alias resolves in CmdRegistry::resolve before the arity check in effect_cmds.rs:204.\n3. The refusal states the ARITY, not the SHAPE, so it is unactionable: \"requires 1-2 argument(s), got 6\" does not suggest quoting.\n\n## Why the help escaped the guard that would have caught it\nhelp.rs derives HelpLine::Keys rows from the keymap and DROPS a row whose command resolves to nothing, guarded by every_help_page_key_row_names_keys_that_exist. The ex-commands are HelpLine::Literal rows — the part that escaped the derivation. That is the whole unguarded surface and this is what was in it.\n\n## The non-broken path, worth keeping in mind\nThe formula panel (F, then n) takes free text `Name = expression` and works on both surfaces. The help is pointing new users at the one door that is jammed.\n\n## Acceptance Criteria\n- Quote the examples in all three places: :formula Product \"Total = Widget + Gadget\"\n- The welcome popup's `\u003cexpr\u003e` becomes `\u003cName=expr\u003e`; `\u003cexpr\u003e` alone is not accepted.\n- The refusal names the command as typed and states the SHAPE: formula: expected `formula [\u003ccategory\u003e] \"\u003cName\u003e = \u003cexpr\u003e\"` — got 6 words; quote the formula.\n- Check the four asciinema casts in docs/: if any shows the unquoted spelling it inherits this and needs re-recording.\n","notes":"FIXED in PR #131 (merge 9d2bdd3).\n\nPR #126 HAD NOT CHANGED THE SYMPTOM -- checked before reproducing from this\nticket's text, as asked. improvise-55l5/#126 changed KeymapSet::dispatch -\u003e\nregistry.interactive; this message comes from registry.parse, the HEADLESS path,\nuntouched.

This one is a potential LOST/MISDIRECTED WRITE and deserves settling before it is dismissed.\n\nweb/app.js:146 — `if (editing) return;` in repaint. So while the DOM editor is open the screen is frozen. But onFrame() KEEPS FOLDING: client.on_frame(text) runs before repaint() and is not guarded. The cache moves while the screen does not.\n\nedit(td, row, col, seed) captures VIEWPORT COORDINATES at paint time (:336), and commit calls client.typed_cell(row, col, input.value) (:360), which resolves (row, col) against the CURRENT GridCache — not the one the user was looking at.\n\n## Steps to Reproduce\nTwo clients on one ws-served document. Browser user clicks the cell showing North / Revenue and starts typing. Another client (or the TUI host) hides an item above it, or toggles a group — the rows renumber. The browser folds the new RowFrame and Cells silently; the screen still shows the old table.

Two keystrokes to reach, with pruning on.\n\n## Acceptance Criteria\n- A header whose run is empty BECAUSE IT IS COLLAPSED survives pruning.\n- A header whose run is empty because every item pruned away still goes.\n- A test distinguishing those two, or the fix is satisfied by never pruning any header.\n\n## Note on the fix\nNot a one-liner and worth deciding deliberately. prune_axis_items cannot tell the two cases apart: GridLayout drops the \u0026View after construction.

The wave-I\nhand-back for improvise-t6db reported this hazard as \"argued and NOT observed\",\non the strength of a fixture that was said to put Product on the None axis in\none view and on Column in another. It did not: add_category defaults a new\ncategory to Column and nothing moved it, so all three views had none_cats\n{_Index, _Dim} and the stated input to the hazard was absent. An unprobed path\nreported as a negative result. Setting Product to Axis::None explicitly made the\nproperty test fail on the first run.\n\nMECHANISM. App::rebuild_layout calls recompute_formulas(\u0026none_cats) for the\nHOST's view, populating Model::formula_cache. project::grid_in on the elsewhere\npath builds the other view's GridLayout against that same, stale cache. The\ncache is keyed by the coordinates the recompute used, so with Product on None in\nthe host's view the Total cells are keyed WITHOUT a Product coordinate; the other\nview, which has Product on Column, asks for (Region, Product, _Measure=Total),\nfinds nothing, and -- because prune_empty is on -- drops both Total columns.\n\nMEASURED, two-view fixture, formula Total = SUM(Revenue):\n\n  host on Second, projecting Second   6 columns  incl.

The wire carries Command::ChangeMode(AppMode::Normal); improvise-protocol/src/reduce.rs:195 folds it as `view.mode = mode.clone()` with no resolution. improvise_protocol::resolve — re-exported as improvise_wasm_client::resolve, and the LIVE browser resolver; keys.rs holds only BrowserKey — emits it at resolve.rs lines 369, 692, 972, 1461, 1613 and 2045.\n\nDemonstrated with a lockstep-shaped probe (resolve + ClientState::fold against reduce_key; enter records with R, open a panel, Esc):\n    left:  Normal          (client)\n    right: RecordsNormal   (host)\n\n## What the bad state then breaks\nresolve.rs:685 commit() early return — host counterpart CmdContext::is_records_mode() via CommitAndAdvance. The client is meant to DECLINE a records commit it cannot compose. With the mode wrong it does not decline: it composes typed_cell_command(id, \u0026text) and a Basis claim against a records grid, whose columns are [coords.., +cat, measures.., +] (gotcha 1). That is A WRONG WRITE, strictly worse than the black hole it was written to produce.\n\nresolve.rs:708 create_column() exit mode — picks Normal where it should pick RecordsNormal, re-entering the same wrong state after every column creation.

The client returns None to decline what it cannot name; with the mode wrong it clamps and re-enters, so TAB AT THE BOTTOM-RIGHT OF A RECORDS GRID SILENTLY STOPS APPENDING ROWS.

Its records coverage (typing_at, records_pair) sets host.view_state.mode = AppMode::records_editing() by ASSIGNMENT and seeds the client with client.view = app.view_state.clone() — it starts from a state where mode and layout ALREADY AGREE, and every divergence above requires them to disagree. A guard seeded on agreement cannot detect drift: the same vacuity shape as gotcha 36's bystander already sitting on the relayed value.\n\n## Acceptance Criteria\n- lockstep DRIVES THE KEYS into records mode and back out of a minibuffer rather than hand-placing the mode. Without this, any fix is unguarded.\n- The projection carries what the client needs to settle the mode (gotcha 47: where a client cannot compose the answer, ENRICH THE PROJECTION rather than moving resolution back).\n- All three decision points answer the same question the host answers.\n- Or: a written argument that ChangeMode(Normal) should not be on the wire, plus its removal — which still leaves the substitution at the three sites.\n\nDo NOT close this by having the client re-derive records-ness from the axes: that is a second derivation, improvise-edp's disease.\n","status":"closed","priority":2,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-21T11:04:35Z","created_by":"Edward Langley","updated_at":"2026-09-21T20:15:01Z","closed_at":"2026-09-21T20:15:01Z","dependency_count":0,"dependent_count":0,"comment_count":0}

It also sits awkwardly beside this crate's own rule (gotcha\n37(d), gp.md §11: the check asks the document, never the name's shape) and\nbeside a_coordinate_is_spelled_as_one_even_when_an_item_shares_the_one_hots_name,\nwhich exists precisely to show the two spellings cannot collide.\n\nNeither NumericCategory nor AbsentCoordinate has a test today; they were\ninvented by the wd6n branch and only three of the five families are reached by\nits fixture.\n\n## Acceptance\n\nA fit over a view with a numeric-valued or date-valued regular category emits a\n`Cat IS Item` coordinate for it rather than being refused, demonstrated by a\ntest that fails before the fix.

{"_type":"issue","id":"improvise-mcq4","title":"The frame fingerprint is a 4x regression on the held-key path improvise-748f just optimized","description":"MEASURED, not suspected. Found while merging PR #78 (improvise-ni6k) with PR #76 (improvise-748f), which landed first.\n\nimprovise-748f split the geometry fingerprint so that a batch which writes NO cell -- the held-key path, [/] and axis cycle and hide/show -- stays O(config) instead of walking 18,000 cells. improvise-ni6k's App::view_frame builds a GridLayout per view via with_frozen_records, and with_frozen_records applies prune_empty, and prune_empty WALKS CELLS. So for a view with prune_empty on, ni6k puts the O(cells) walk straight back onto the path 748f had just taken it off.\n\nMEASURED on the merged tree, benches/reshape_observation.rs, one CycleAxis batch, prune_empty ON, frame fingerprint disabled vs enabled:\n\n  400 cells      93.6us  -\u003e   283.2us   3.0x\n  9,600 cells     1.97ms -\u003e    7.34ms   3.7x\n  18,000 cells    3.04ms -\u003e   12.41ms   4.1x\n  90,000 cells   28.5ms  -\u003e   91.7ms    3.2x\n\nThe 16.7ms frame budget is crossed at 18,000 cells, where the pre-fingerprint tree sat comfortably inside it at 3.0ms.\n\nWHY 3-4x AND NOT 2x: view_frames builds every view's layout, before AND after each model effect. The bench fixture has two views, so that is four pruned layout builds against the one rebuild_layout already does.\n\nWHY THE COST WAS NOT SEEN EARLIER: ni6k's own benchmark measures a SetCell batch, where 748f's document_content walk dominates and the fingerprint reads as +2 to +5 percent. And the geometry case, when first added, used the dense_app fixture as-is -- prune_empty OFF -- where with_frozen_records does not walk cells at all and a CycleAxis batch reads 17-176us. THAT FIXTURE MEASURES THE CHEAP HALF AND CALLS IT THE COST. It is the same non-discriminating-fixture failure this repo names everywhere; the numbers above come from turning prune_empty on, and the benchmark now does.\n\nOPTIONS, none taken:\n- Fingerprint only the ACTIVE view for the cursor and fall back to the cheaper config hash (last_reshaped_views) for the client audience. Over-resets bystanders on other views, which is the safe direction per gotcha 35, and removes the per-view multiplier. Probably the right answer.\n- Memoise the pruned layout across the before/after pair.\n- Accept, on the argument that prune_empty plus a large document plus a held key is rare. That argument needs the user, not an agent.\n\nDO NOT close this by re-running the benchmark with prune_empty off.","notes":"FIXED to 1.9x, not closed: one pruned build per model effect remains.\n\nThe coordinator ruled this must be fixed before PR #78 lands, and was right -- a cost measured to four significant figures is a decision to ship, not a thing to file.\n\nWHAT WORKED, AND IT IS NOT WHAT THE TICKET PROPOSED. The ticket's first option (and my own suggestion) was to fingerprint only the ACTIVE view and fall back to the config hash for the client audience. Implemented and measured: it bought NOTHING -- 12.41ms -\u003e 12.56ms at 18,000 cells. The bench's second view is one created fresh with everything on Axis::None, so building it costs nothing. THE PER-VIEW MULTIPLIER WAS NEVER THE COST; two EXPENSIVE builds were. That is only known because it was measured after implementing rather than reasoned about before.\n\nWHAT ACTUALLY WORKED: the opening basis is free. At batch start App::layout already IS the active view's pruned layout, so opening_view_frame() hashes it instead of building a second one. frame_of() is the shared hash and view_frame() builds then calls it.\n\n  one CycleAxis batch, prune_empty ON:\n                     before      after     fingerprint off\n      400 cells     283.2us    167.0us            93.6us\n    9,600 cells      7.34ms    3.879ms           1.967ms\n   18,000 cells     12.41ms    5.752ms           3.043ms\n   90,000 cells     91.69ms    56.54ms           28.52ms\n\n4.1x -\u003e 1.9x at the canonical size, back inside the 16.7ms frame budget.\n\nTwo guards on the free basis: it is gated on drill_state.is_none(), because a drill freezes the record list and the held layout is then not what view_frame would build; and it is opening-use only, because App::layout is stale mid-batch (gotcha 23).\n\nTHE NARROWING WAS KEPT anyway, because it is the honest shape -- the cursor's question is about one view. The audience half is now the config diff observe_reshape already computes free. It over-reports (safe direction) and is read only behind the epoch gate in adopt_cursor_epoch, so its imprecision cannot reach a batch that reframed nothing. a_reshape_of_one_view_leaves_a_client_on_another_view_alone still passes, so it has not widened into improvise-nynk's negative arm.\n\nBOTH SUBSUMPTION PROOFS RE-RUN AFTER THE NARROWING, since narrowing is exactly what could quietly stop covering something: #76's own two arms still pass with no per-effect reset anywhere; AddFormula/RemoveFormula and SortData are still covered; disabling the narrowed observation fails ten tests.\n\nWHAT REMAINS, AND WHY THIS STAYS OPEN: one pruned layout build per model effect. The LAST one duplicates work rebuild_layout does immediately afterwards, and eliding it means moving the check after the loop -- which is the position that clobbers a deliberate cursor placement in the same batch (the three records-mode tests that caught it the first time). A restructure that knows which effect is last, including on abort, is possible and was not attempted at this hour.\n\nThe benchmark now carries the held-key case with prune_empty ON and a comment saying not to turn it off, because that fixture is the only reason any of this was visible.\nTHE NARROWING BOUGHT ITS SPEED PARTLY WITH CORRECTNESS, and the adversarial review of PR #78 caught it. Correcting my own note above.\n\nI narrowed the frame fingerprint from every view to the active one, measured that it moved 12.41ms to 12.56ms, kept it anyway \"as the honest shape\", and reported that it bought nothing. It bought a P1: a CellData write that prunes a row out of ANOTHER client's view became invisible. view_shapes is config-only -- it hashes the prune_empty FLAG, not which rows survive -- so last_reshaped_views is empty, the one-view frame covers only the host's, and the bystander is never sent ResetCursor while its grid loses a row. Gotcha 24's permanently-stale case.\n\nTHE LESSON I WANT ON THIS TICKET: a measurement showing a change is free is not evidence that it is correct. I answered \"what does this cost\" and reported the answer as though it had also answered \"is this right\". The two questions were asked in the wrong order and only one of them was asked at all.\n\nTHE REPAIR, and the cost trade is accepted deliberately rather than hidden:\n- LayoutGeometry arm keeps the cheap one-view frame. view_mut() writes only the active view, and the structural cases (AddCategory, RemoveCategory, Add/RemoveItem) are already covered by view_shapes.\n- CellData arm restores the all-views frame, because a cell write can prune a row out of any view.\n\n  Measured, my own numbers, one batch, prune_empty ON:\n    held-key (CycleAxis)  18k cells   5.69ms  -- UNCHANGED, 0%\n    SetCell               18k cells  10.66ms -\u003e 11.26ms   +5.7%\n\nThe +5.7% scales LINEARLY IN VIEW COUNT on the CellData arm. A ten-view document pays it ten times. That is the trade and it is accepted, not hidden.\n\nTHE ABSOLUTE, stated plainly because it should not be discovered later: even after the mcq4 fix, this PR roughly DOUBLES held-key latency on large pruned documents -- 3.04ms to 5.69ms at 18,000 cells -- and 56ms at 90,000 cells is 3.4 frames. The 16.7ms budget is respected at the canonical size and is not respected at the pathological one, which was also true before at 28.5ms.\n\nA SECOND BUG FOUND WHILE WRITING THE REGRESSION TEST, filed as improvise-t6db: the test's precondition failed because grid_in built a non-active view with GridLayout::new, which does not prune. The bystander's projected grid never lost a row, so the P1 was unobservable -- a bug hiding a bug.\n\nSTILL OPEN, unchanged: one pruned build per model effect. The last duplicates rebuild_layout and can only be elided by moving the check after the loop, which clobbers a deliberate cursor placement in the same batch. With the arms now split, moving the LayoutGeometry arm alone after the loop fails 2 tests; the reviewer measured 4 against the unified arm before the split.\n","status":"open","priority":2,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-21T04:20:08Z","created_by":"claude-agent-protocol","updated_at":"2026-09-21T05:00:28Z","dependencies":[{"issue_id":"improvise-mcq4","depends_on_id":"improvise-pmt0","type":"parent-child","created_at":"2026-09-25T01:05:06Z","created_by":"Edward Langley","metadata":"{}"}],"dependency_count":0,"dependent_count":0,"comment_count":0}

The claim in both doc comments is that a new variant cannot be omitted, because after() has no None arm so the only way to answer for a new variant is to NAME ANOTHER ONE.\n\nThat is half true and the half it gets wrong is the half that matters. ANSWERING after() FOR a new variant is forced by the compiler. POINTING AN EXISTING ARM AT IT IS NOT. A probe variant whose after() arm returns some existing variant, with nothing in the cycle pointing back to it, is simply never walked: all().len() came back 17, not 18, with the suite green.\n\nSo the consolidation replaced five grep-visible lists with one derivation whose totality is asserted in prose and checked by nothing. THE REVIEWER'S META-POINT IS THE REAL TICKET: five disagreeing AppMode lists were visible to grep; all() under-enumerating is visible to nothing. A consolidation owes a test that the surviving derivation is TOTAL, not merely that it agrees with what it replaced.\n\nWHAT IS STILL BETTER THAN BEFORE, so this is not a revert: the compiler now forces a human to look, and two of the five lists it replaced were ALREADY WRONG (both missing SavePrompt). This is a gap in a guarantee, not a regression.\n\nOPTIONS, roughly in order of cost:\n- A test that walks the cycle and asserts every variant is visited, driven by something independent of after() -- which needs an independent enumeration, and that is the problem restated.\n- A derive macro or a dependency (strum). Rejected during PR #78 only because adding a workspace dep mid-wave collides in Cargo.toml; on its own it is the honest answer and cheap.\n- Accept and document the residual precisely, replacing both doc comments, which currently overclaim.\n\nWHATEVER IS CHOSEN, FIX THE DOC COMMENTS FIRST: they presently say the omission is impossible, and a reader checking this property will believe them.

Its comment said \"a fourteenth declaring LayoutGeometry must come here and say so\". That is false for exactly the reason this ticket names: adding is compiler-forced only where an EXISTING arm must point at the new thing, and here nothing must. `assert_eq!(cases.len(), 13)` is a count, not a totality check -- it catches a case being deleted from the list, never one being absent from it.\n\nCorrected in #78 to say what it is rather than what it is not; the mechanism is unchanged and the cursor consolidation does not depend on it. Filed here rather than fixed because the honest fix is whatever 5ubs settles on, and a fourth hand-rolled attempt in a fourth place is the disease.\n\nWHAT MAKES THIS ONE WORTH RECORDING: it is the same defect as AppMode::all(), in the PR whose own consolidation work surfaced AppMode::all().

The artefact is worth more preserved than rushed.\n\n---\n\n### A check that looks like the answer, answering a neighbouring question\n\nThe characteristic defect in this repo is not a wrong line; it is a check that is *adjacent* to the thing it names. Three instances landed in one campaign (PRs #59/#60), in three different layers, which is why it is worth stating as a shape rather than three gotchas:\n\n- **A vacuous assertion.** `set_panel_open_and_cursor` asserted `category_panel_open` was true after an effect set it true -- once the launch default supplied `true`, the effect could be replaced by a **no-op** and 1391 tests passed. It answered *is the flag true* where it meant *did the effect set it*.\n- **A vacuous repair of it.** The first fix folded `[open:false, open:true]` and asserted the final state -- which a reducer that folds nothing also satisfies. It answered *does the text mention the other direction* where it meant *does the writer move the flag both ways*. **Reading the diff is what failed**, and it failed because the vacuous version contained `open: false`.\n- **A clean auto-merge.** `git merge-tree` reporting no conflict answers *can git combine these texts*, where the question is *does the combination do what both sides meant*. Two PRs edited the same four files with no conflict and neither side CI-tested together.\n\nEach has the same remedy shape: **name the question you actually mean, then find an input that separates it from its neighbour.**\n\n- For an assertion: **assert the direction the default cannot supply.** Closing the panel discriminates; opening it proves nothing.\n- For a repair: inject a **one-directional** fault (`if open { set true }` -- can raise, never lower). A vacuous repair cannot see it, because a test that only asserts the `true` direction is satisfied by a writer that only ever writes `true`.\n- For a merge: **materialise it and run the gates**, and check that a count which should MOVE actually moved. Playwright going 16 -\u003e 17 is what showed the other side survived; \"no conflict\" and an unchanged total would both have been consistent with losing it.\n\nThis generalises the existing `doctrine(fold_tests_must_test_order_not_the_axiom)` (asserting `fold(prefix)+fold(rest) == fold(whole)` is the definition of a left fold, so it answers a neighbouring question too). What the campaign adds is that the pattern recurs in **test repairs** and in **merge hygiene**, not only in production code and not only in fold tests.\n\n---\n\nAcceptance: the section is in §7; `doctrine(fold_tests_must_test_order_not_the_axiom)` cross-references it or is subsumed by it.

With it stuck true, pressing `C` on a CLOSED category panel decides to *close* it rather than open it — the panel becomes unopenable by its own key — and no test notices.\n\n**Why it is invisible:** `cmd/mod.rs`s `test_helpers` sets `category_panel_open` explicitly on the context it builds, so no command test ever exercises the real propagator. The tests construct the value they then assert on.\n\n**This is PRE-EXISTING and was not caused by the launch-default ruling (PR #60).** That distinction was established by control rather than assumed: with the default inverted, this mutation fails *exactly the same two tests as inverting the default alone* and nothing more. So it was unguarded before the ruling too. The remedy is therefore \"a test at all\", not the precondition-stating fixture that fixed the two genuinely-disarmed tests (`set_panel_open_and_cursor`, `panel_commands_address_the_named_panel_only`).\n\n**The method that found it is worth more than the finding** and is written up in `context/test-evidence/clients.md` under \"How to know a launch default has stopped disarming things\": mutate every site that writes, propagates or reads the value; sites where nothing fails are suspects; then re-run each suspect with the default inverted to separate *vacuous* (fix the fixture) from *unguarded* (file it). Grep cannot do this — it finds sites that NAME the flag, not tests that merely start from a default-built state.\n\nAcceptance: a command-layer test that drives the real `App::cmd_context` rather than a hand-built context, such that `toggle-panel-and-focus` on a closed panel opens it; proved by hardcoding the propagator and watching it fail.\n\nSibling note: `improvise-wasm-client/src/render.rs` has the same propagator shape for `RenderModel`. Hardcoding THAT one true is improvise-wsaw reintroduced one layer up, and Rust sees nothing — only the Chromium harness catches it, at `contract.spec.js`s `toBeHidden`.

This is what the TUI runs.\n- `crates/improvise-protocol/src/reduce.rs` — `reduce_view`'s `Command::SetPanelOpen` arm, the same three-way match writing the same three fields on a client's own `ViewState`. This is what the browser folds.\n\nFound while repairing the fallout of the launch-default ruling (PR #60). Both copies' Category arm had gone vacuous for the same reason, and **each had to be fixed independently** — the Chromium harness passed 3/3 against a no-op'd `effect::SetPanelOpen`, correctly, because the browser never executes it. That is the tell: a fault in one copy is invisible to the other's tests by construction.\n\nThis is design-principles §5's named disease (\"a derivation done twice is the defect, even when both copies are correct today\"), and it is the same shape as improvise-edp (the category tree flattened twice) and gotcha 44 (the grid frame derived twice). Both of those were cured by moving the derivation to one home both ends call.\n\nWhy it is filed rather than fixed in #60: the fix is a shared `fn set_panel(view: \u0026mut ViewState, panel: Panel, open: bool)` in `improvise-protocol` that both arms call, and that is a change to the effect layer's shape rather than to the pointer work #60 is about. It is also not urgent — both copies are correct today, and now both are guarded.\n\nTwo things to preserve when fixing it:\n\n1. **The cure is one home, not a test holding two copies in step.** `doctrine(a_consolidation_that_keeps_its_compatibility_test_is_unfinished)` — if the fix leaves a \"the two agree\" test alive, it is not finished.\n2. **`Panel::ALL` already exists** in `ui/app.rs` and drives the toggle keys, so a fourth panel reaches every keymap from one entry.

No TUI test covers the launch frame at all.** The browser half is asserted end to end in `harness/tests/contract.spec.js` (visible with no keypress, and `C` still hides it — two states, because either alone passes against the wsaw bug). The terminal half is asserted nowhere: nothing renders a first frame and looks at it. So the sidebar could vanish from the TUI, or appear when it should not, with the suite green. That is not a regression this PR introduced — the launch frame was never covered — but the PR is what made the launch frame carry a decision.\n\n**2. The panel-focus cycle with all three panels open is now untested, and the uncovered case MOVED rather than shrank.** `panel_focus_cycles_from_the_focused_panel_not_the_first` used to inherit \"category panel closed\" from the default; it now states that precondition explicitly, which is the right fix and preserves what the test is for (skipping a *closed* panel). But the state nothing covers is now the launch-adjacent one: all three open. Worth a case.\n\nNote what should NOT be done here: do not re-derive the launch state from anywhere else. It is stated in exactly one place (`ViewState::default()`), asserted by exactly one Rust test (`a_fresh_session_opens_with_the_category_panel`, which also asserts the other two panels stay shut so it cannot pass against a default that opens everything), and reverting it fails exactly that one test under `--no-fail-fast`. That shape is correct and a second statement of the fact would be the disease.\n\n**This ticket is also the place to record a refinement if the user scopes the ruling back to the browser.** If they do, the change is NOT \"special-case the browser\" — it is to give the two front ends different *initial* values through something that is not a shared default, and the argument for why that is not a divergence would have to be made first.\n\nAcceptance: a TUI test that renders the first frame and asserts the category panel is drawn; the all-three-open cycle case; both proved by injection.\n","status":"closed","priority":2,"issue_type":"task","owner":"el-github@elangley.org","created_at":"2026-09-20T21:01:46Z","created_by":"wave3-webui","updated_at":"2026-09-20T21:10:59Z","closed_at":"2026-09-20T21:10:59Z","close_reason":"User ruled BOTH (TUI + browser); TUI launch frame now tested in tests/tui_launch_state.rs","comments":[{"id":"547f7ff6-32fa-556f-8479-9c6be120a2d9","issue_id":"improvise-4ibz","author":"wave3-webui","text":"ANSWERED by the user, 2026-09-20, relayed through the orchestrator: **BOTH**.

The TUI launch frame is tested.** `tests/tui_launch_state.rs` (root crate — the TUI's own crate), three tests:\n- `the_terminal_app_launches_with_the_category_panel_open`\n- `the_other_two_panels_are_shut_at_launch` — so \"open everything at launch\" cannot pass the first\n- `the_terminal_constructor_inherits_the_shared_default_rather_than_setting_it` — walks `Panel::ALL` comparing `App::new` against `ViewState::default()`, which is what would catch a TUI-only launch state being reintroduced (the divergence improvise-wsaw closed)\n\nNot a rendered-frame test: design-principles §7 says not to test ratatui `Widget::render`, and there is no `TestBackend` anywhere in the repo. The honest target is the TUI's own constructor; `src/draw.rs`'s one-line read of the flag stays argued-not-tested per gotcha 48. Proved by injection — putting the default back to `false`, and separately making `App::new` override it, each fail the expected tests and only those.\n\n**2. The all-three-panels-open cycle: deliberately NOT added, and the reviewer's reasoning is better than the diff-size one I gave.** `panel_focus_cycles_from_the_focused_panel_not_the_first` is about *skipping a closed panel*; that is its property and it is correctly pinned by its now-explicit precondition. A three-open case tests plain rotation, which the two-open assertions already establish structurally. Not a gap.\n\n**What this ticket did not predict, and is the most valuable thing it produced.** A launch default **disarms every test that asserted the thing the default now supplies**. Three tests asserted `category_panel_open` was *true* after doing something to make it true, and all three then passed without the code under them working:\n\n- `set_panel_open_and_cursor` (`ui/effect.rs`) — the serious one. With it vacuous, `effect::SetPanelOpen`'s Category arm could be replaced by a **no-op** — `C` doing nothing in the terminal — and the entire workspace stayed green at 1391 tests.\n- `panel_commands_address_the_named_panel_only` (`reduce.rs`) — the browser's copy of the same mapping, vacuous the same way. **Its first repair was ALSO vacuous**, which is the subtle part: folding `[open:false, open:true]` and asserting the final state is *true* still passes against a reducer that folds nothing, because the default already supplies `true`. Only asserting the **`false`** direction discriminates.\n- `panel_focus_cycles_from_the_focused_panel_not_the_first` — inherited its precondition from the default; now states it.\n\n**The rule to carry: assert the direction the default cannot supply.** Closing the panel is the discriminating move; opening it proves nothing. Every one of these was caught by injection, not by reading — including the failed first repair, which reported NONE failing and would otherwise have shipped looking fixed.\n\nOne thing filed rather than fixed: **improvise-56ek** — `effect::SetPanelOpen` and `reduce_view`'s `Command::SetPanelOpen` are two three-way matches in two crates, so a guard on either says nothing about the other, and both had to be repaired independently here.\n","created_at":"2026-09-20T21:10:58Z"}],"dependency_count":0,"dependent_count":0,"comment_count":1}

Gotcha 47 says every KeyOutcome::Upstream is a black hole —\nHost::handle answers ClientFrame::Key with an explicit empty vec — so any key\nthe app ADVERTISES and then resolves upstream does nothing at all in a browser\nand reads as broken rather than as unavailable.\n\nTHE LIST, advertised in a hint line AND unhandled by resolve::step:\n\n  \u003e        drill-into-cell            Normal            (fixed in PR #59)\n  P        toggle-prune-empty         Normal\n  R        toggle-records-mode        Normal\n  o        add-record-row             RecordsNormal\n  d/Del    delete-formula-at-cursor   FormulaPanel\n  :        enter-mode command         Normal, RecordsNormal, FormulaPanel,\n                                      CategoryPanel, ViewPanel, TileSelect\n\nThe `:` row is a DIFFERENT case and must not be lumped in. Its name IS handled;\nit is refused on purpose by strands_the_user, because CommandMode is a prompt\nthis client can enter but cannot commit — a dead room is worse than a locked\ndoor. So for `:` the refusal is RIGHT and only the silence is wrong. Fixing it\nmeans saying so, not implementing it.\n\nHOW THE CROSS-REFERENCE WAS MADE, because the method is reusable and the naive\nversion is wrong. help::advertised() is a table of (command, args, caption) —\nCOMMAND NAMES, not text — so the hint line can be crossed against what\nresolve::step handles exactly, with no tokenisation of the rendered string and\nno guessing which character in \"hjkl arrows :nav\" is a key. Anything that\ntokenises the hint TEXT is solving a harder problem than exists.\n\nMY FIRST PASS OVER-REPORTED AND I ALMOST BELIEVED IT. Resolving every bound key\nagainst an EMPTY ClientState flags edit-or-drill, commit-cell-edit,\ncreate-and-switch-view, page-prev/page-next and delete-formula-at-cursor as\nupstream — but most of those are handled names refused by STATE (no cell under\nthe cursor, no published basis), which is correct behaviour and not this bug.\n\"Upstream in an empty fixture\" and \"the name is unhandled\" are different\nquestions, and the first is not evidence for the second. The list above is the\nsecond, separated by checking each name against step's arms directly.\n\nAND THE NAMED LIST IS HONEST FOR ONE MODE ONLY — this is the point with reach.\nresolve.rs's `the_command_names_that_still_need_the_host_are_these` is the\nguard gotcha 47 says must be kept accurate, and it IS accurate — but it is\nbuilt with in_mode(AppMode::Normal), so it only ever asks about Normal-mode\nbindings. add-record-row (RecordsNormal) and delete-formula-at-cursor\n(FormulaPanel) are outside its reach entirely: they could never have failed it.\nA named list that silently scopes itself to one mode is a guard that LOOKS\nbroader than it is, and that is the same shape as every other defect this repo\nkeeps finding — a check passing while the thing it names is unexamined.\n\nTHE DECISION THIS TICKET WANTS, which is why nothing beyond `\u003e` was touched:\n\n  (a) Do the same interim for the remaining five: each says what is true, in\n      the client's existing status mechanism. Cheap, honest, reversible, and\n      each needs its own TRUE wording — the `\u003e` fix was nearly routed through a\n      message about aggregates, which would have been true-sounding about the\n      wrong thing and worse than silence.\n  (b) Implement some of them client-side instead. toggle-prune-empty and\n      toggle-records-mode are view-shape changes and may be composable from\n      existing ModelCommands; add-record-row and delete-formula-at-cursor\n      touch the document and need checking against gotcha 38 first.\n  (c) Make the class unrepresentable: a test asserting that every command named\n      by help::advertised() either resolves locally or appears on a per-mode\n      exemption list. That is the \"make the wrong thing impossible\" move and it\n      would have caught all six at once. It is also the only option that stops\n      the SEVENTH appearing.\n\nI did not pick. (c) is the one I would argue for, and it is independent of\nwhether (a) or (b) happens to the five.\n\nNot chased: whether any key is advertised in a hint for a mode whose keymap\ndoes not bind it at all. every_hint_key_resolves_in_its_mode covers that from\nthe keymap side, so it should be empty — but I did not verify it, and it is the\nmirror-image question.","status":"closed","priority":2,"issue_type":"bug","assignee":"claude-wasm-keys-agent","owner":"el-github@elangley.org","created_at":"2026-09-20T20:23:03Z","created_by":"wave3-webui","updated_at":"2026-09-21T00:24:01Z","started_at":"2026-09-20T23:21:14Z","closed_at":"2026-09-21T00:24:01Z","close_reason":"Fixed and merged: rmvx/fdt6/gcvb in PR #71, the harness four in PR #72.

For the host, resolving means the registry answers. For a browser, it means `resolve::step` answers with `Some` rather than falling through to `KeyOutcome::Upstream`. The list of keys that legitimately still need the host already exists as `the_normal_mode_keys_that_still_need_the_host_are_these`, so the check is plausibly: every key named in a hint either resolves locally or is on that named list — which also forces closing one to come and say so.\n\nOne live instance, for scale: `\u003e` was advertised and silent, and that was one of six.

Mode stays VIEWS, the row list is byte-identical before and after, the active marker does not move, the panel cursor does not move.\n\nWHY THIS IS THE ONE A USER HITS FIRST: a user who has just learned that category rows are clickable will click a view row and read the silence as broken — which is LITERALLY the bug report that produced improvise-7ybz ('I can't expand categories' meant 'clicking does nothing'). Shipping the cure for one panel and not its two siblings reproduces the original report.\n\nIt is also the CHEAP one: the resolver already has everything. view_at_cursor, switch-view-at-cursor and delete_view_at_cursor exist, and the formula panel already has a formula_cursor in reduce_view's SetPanelCursor arm. Click::ViewRow(usize) under the commit's own stated rule is a near-copy of click_category_row.\n\nADJACENT, same class, lower confidence and not chased by the reviewer: grid GROUP HEADERS (th.group) are collapse-toggles in the TUI and are not clickable here either; row/column header \u003cth\u003es likewise.\n\nNOT covered by the drill work: improvise-gd28 is refused-by-design because no wire vocabulary exists.

Applied to\nthe tile bar it gives: select the tile AND cycle its axis, because Enter in\nTileSelect is cycle-axis-for-tile. So there is NO click that merely selects a\ntile. A user cannot point at a tile to inspect it, or to see which one they are\nabout to act on. It is the one widget where a single click MUTATES THE DOCUMENT\n— every other click in the page moves a cursor, opens a panel, or expands a row.\n\nThat is consistent with the rule and it may still be wrong. A pointer carries an\nexpectation a keyboard does not: `T` then arrow then Enter is three deliberate\nacts, and collapsing them into one click removes the step where the user sees\nwhat they have selected before committing. The keyboard equivalent of \"click\"\nis arguably `T`+arrow (select), not `T`+arrow+Enter (select and act).\n\nTHE OPTIONS, none of which I have taken:\n  (a) Keep it. One rule, no exceptions, and cycling is reversible in four\n      clicks since Axis::next() is a rotation.\n  (b) A tile click SELECTS only; cycling stays on Enter/Space and r/c/p.

That is a property of the whole pointer story, not a tile-specific concession, and the strongest version of the argument is a consequence the ruling was made without: a tile cycle is an `EffectKind::Model(LayoutGeometry)` change, so it bumps `App::cursor_epoch`, which `Sessions::adopt_cursor_epoch` broadcasts as `Command::ResetCursor` **to every connected client** (gotcha 24). A single stray click therefore used to cost every other viewer their cursor position. The pointer is the easiest input to trigger by accident, and it was wired to the one class of change that reaches other people.\n\n**What it cost, accepted knowingly.** Two clicks for the common action, and a **deliberate divergence from the keyboard**, where `Enter` cycles in one keystroke. Record it as a divergence chosen on purpose, not an inconsistency to tidy later — otherwise someone reads the keymap and \"fixes\" the pointer to match, which silently reinstates the broadcast-on-accident.\n\n**The implementation detail that is easy to get wrong.** \"Already selected\" must be `mode == TileSelect` **and** `tile_cat_idx == index`. The index alone is not enough: `tile_cat_idx` is 0 before anything has selected anything, so an index-only test reads tile 0 as already selected and cycles it on its very first click — the guarantee then holds for every tile but one. And \"second click\" must mean *on the already-selected tile*, not merely the second click of a session, or clicking A then B cycles B and the guarantee holds only for a session's first click. Both are asserted (`the_first_click_on_tile_zero_selects_it_like_any_other`, `clicking_a_different_tile_selects_it_rather_than_cycling_it`).\n\nEvidence discipline: the non-mutation is asserted **positively as well as negatively** — a test saying \"the axis did not change\" passes against a page where nothing happened at all. The fixture publishes a basis deliberately, so a missing `Command::Model` is a decision rather than a client that could not compose one.\n","created_at":"2026-09-20T20:41:14Z"}],"dependency_count":0,"dependent_count":0,"comment_count":1}

The arithmetic is not subtle: the player is\ntold `cols: 120`, the container is ~356px wide inside the page's 16px gutters,\nand 356 / 120 gives about 3px per character, so the player scales the font down\nto 4.83px to fit. Desktop is **13.11px** and perfectly fine, so this is purely a\nnarrow-viewport effect and nothing about the current desktop rendering needs to\nchange.\n\nWHY THE PRIORITY IS HIGHER THAN IT LOOKS: until the user's ruling on\nimprovise-kh8 the landing page sat at `/landing/` and this was a page few people\nwould reach on a phone. It is now the SITE ROOT — the first thing a phone\nvisitor sees is four panels of unreadable grey mush above the call to action.\n\nPROPOSED FIX (the reviewer's, and it is the right shape): stop asking the player\nto fit 120 columns into the viewport and let it overflow instead —\n`overflow-x: auto` on `.player`, plus either `fit: false` or an explicit\n`terminalFontSize` in the `AsciinemaPlayer.create()` options, so the font is\nchosen rather than derived from the width.\n\nONE THING TO CHECK WHEN FIXING, because getting it wrong trades this bug for a\nworse one: the overflow must be contained INSIDE `.player`. A fix that lets the\npage itself scroll sideways breaks the whole document on a phone rather than one\nsection of it. The check is that `document.documentElement.scrollWidth` still\nequals `clientWidth` at 390px afterwards.\n\nNOTE A CANDIDATE that would close this for free: improvise-2oxt re-records the\ncasts. If they are re-recorded at a narrower geometry than 120 columns, the\narithmetic changes by itself — so whoever takes 2oxt should decide the geometry\nwith this ticket in front of them rather than after.\n\nA fix was written and measured during PR #47 (4.83px -\u003e 11.95px via a\n`max-width: 900px` media query giving `.player` `overflow-x: auto` and an 880px\nmin-width, page scrollWidth unchanged at 390) and then REVERTED on the user's\nruling that this should be filed rather than fixed in that PR. The measurements\nare evidence that the approach works; the code is not in the tree.\n\n## Steps to Reproduce\n\n1. `./web/build.sh \u0026\u0026 ./web/assemble.sh site dev`\n2. `python3 -m http.server 8099 --directory site`\n3.

Press play on any of the four players and read the computed style of\n   `.ap-terminal`: `font-size` is 4.83px.

At 18,000 cells -- the size gotcha 41 already treats as\nrealistic -- a TUI redraw takes about four tenths of a second, and the TUI redraws\non every keypress.\n\nWHY: the whole grid is evaluated roughly THREE TIMES per frame.\n\n1. `ui/viewport.rs::compute_col_widths` walks every (row, col) calling\n   `layout.display_text`, to size the columns.\n2. The SAME function then walks every (row, col) AGAIN summing column totals, to\n   size the total row.\n3. `project::grid_of` then evaluates the visible cells via `cell_display`, and\n   `column_totals` sums every row again for each visible column.\n\nEvery one of those goes through `Model::evaluate_aggregated`, and every result is\nthrown away at the end of the frame.\n\nWHAT THIS IS NOT: it is not the viewport question. improvise-i5tk asked whether\nnarrowing the TUI's `GridCache` to its viewport would help, and the benchmark says\nit buys only 1.2-1.5x, because passes 1 and 2 are viewport-INDEPENDENT by\nconstruction -- `compute_col_widths` takes no viewport and a column total must sum\nevery row including scrolled-past ones (gotcha 44). So narrowing removes part of\none pass out of three.

Note what the measurement already rules out: windowing the cache to a viewport is not the fix (1.2-1.5x measured, improvise-i5tk), because compute_col_widths takes no viewport and a column total must sum every row (gotcha 44).

Criterion (1) is\n\"all test plan steps pass in CHROME AND FIREFOX\", and bck's own grooming note\nrecords the standalone deployment as demonstrated by harness/. Both are true of\nChromium and neither is true of Firefox.\n\n`harness/playwright.config.js` declares three projects, and only the chromium\none has no `testMatch`. Firefox and WebKit both carry\n`testMatch: /opfs\\.spec\\.js/`, so `shell.spec.js` — every assertion about\nweb/app.js, including \"the page draws the demo document out of the worker\" and\n\"committing an edit sends one frame and shows the host's value\" — runs on\nChromium alone. The config's own comment says so (\"The shell spec is\nChromium-only\"), and the stated reason is that `routeWebSocket` is slower and\nflakier across three engines.\n\nTHAT REASON APPLIES TO FOUR OF THE SIX SPECS, NOT SIX. The four `?ws=` specs\nmock a peer with `routeWebSocket`. The two under \"the standalone deployment\"\ndo not: they load `/index.html` with no query and drive the in-page worker over\nOPFS — which is precisely the deployment bck's criterion is about, and\nprecisely the code Firefox exercises differently (its OPFS implementation is\nalready run by opfs.spec.js, so the engine is known to support the path).\n\nSo the cheap and honest change is to let the standalone describe block run on\nFirefox while leaving the routeWebSocket block Chromium-only. That is a\n`testMatch`/grep split rather than a third copy of the spec.\n\nWHAT MUST NOT HAPPEN: turning the whole file on for Firefox and then quieting\nwhatever flakes.

{"_type":"issue","id":"improvise-864a","title":"Concurrent merges to main race on one Pages environment and the superseded deploys fail","description":"DIAGNOSED 2026-09-21 (PR #88). The cause is neither direction this ticket offered, and it is not concurrency in the sense the ticket meant.\n\nMEASURED over all 100 push-to-main CI runs 2026-09-19T22:02Z..2026-09-21T05:02Z, from the run/job/step/log APIs:\n\n  12/12 artifact-not-found deploy failures had ANOTHER run's SUCCESSFUL Pages\n        deployment complete inside their own upload-\u003edeploy window\n   2/56 successes had the same\n   0/4  other deploy failures (those are the unrelated 'Create Pages site failed')\n\nDIRECTION IS SETTLED. The oldest run of the 17:47Z batch failed at 17:47:23Z, BEFORE the next deploy started (17:47:31Z) and before any Pages deployment existed at all, since deploy-pages fetches artifact metadata before creating one. It cannot have been caused by its own deploy, by supersession, or by a concurrent one. The artifact was already gone.\n\nTHE DECISIVE OBSERVATION, and it is scoped by artifact NAME rather than by run: run 35560726456 finalized harness-serve, wasm-bundles and github-pages seconds apart, each with an id; 2m21s later its own lookup reported 'Found 2 artifact(s)' with no github-pages. Same run, same token, same call, same retention. That single line rules out service flakiness, eventual consistency, retention, token scope and a v3/v4 backend mismatch simultaneously — any of them would have taken the siblings too.\n\nRULED OUT: queue depth (the three deploys never queued — 9s and 17s apart, each failure taking 1s); retention (all shared retention-days: 1, and the newest-finalized expires LAST, so expiry can yield 0/1/1 or 0/0/1 but never this ticket's 0/1/0); deletion by the action (an upstream feature request asks for that capability, open precisely because nothing does it); action-version drift (successes and failures alternate minute by minute on identically-resolved SHAs).\n\nONE CLAUSE OF THIS TICKET'S OWN CORRECTION IS FALSIFIED. It argued the tip-of-main guard would have skipped the publishing deploy 'and let 52507a6 deploy and fail anyway', assuming 52507a6's loss was independent of its neighbour. It was not: 5f871f7's deploy completed FOUR SECONDS before 52507a6's began. PR #46 aimed at the right quantity for the wrong reason.\n\nIT STILL MUST NOT SHIP. The association is not a mechanism, and the mechanism is not deterministic — 5f871f7 had a foreign deploy land inside its own window and survived. A guard measured at nothing, against a probabilistic effect, is doctrine(measure_the_obvious_fix_before_reporting_it_as_the_fix).\n\n## Acceptance Criteria (REPLACED — the old one asked for the guard this evidence does not support)\n- Either: no two runs hold a github-pages artifact across another run's Pages deployment.\n- Or: narrow the upload-\u003edeploy window and measure the failure rate against it.\n- Before any fix, reproduce deliberately: two pushes seconds apart on a scratch repo, polling /runs/{id}/artifacts every few seconds through both deploys, and watch the github-pages entry disappear at the moment the other deploy completes. Cheap, and it is what turns an association into a mechanism.\n\nFull argument: context/code/tooling.md §3. WHAT IS STILL UNKNOWN: why GitHub removes it. 12/12 vs 2/56 is an association; no upstream issue, changelog or doc describes the behaviour, and both the reaped and surviving artifacts are 404 now (retention-days: 1), so the state is gone.","acceptance_criteria":"A run whose commit is no longer the tip of main skips actions/deploy-pages instead of failing; a burst of merges to main produces exactly one deploy attempt and no red X on the superseded runs.","notes":"CORRECTION 2026-09-20, from adversarial review of PR #46 — THE ORIGINAL DESCRIPTION'S PREMISE IS WRONG, and the fix built on it was closed unmerged.\n\nThe description says only the NEWEST run keeps its artifact. Re-checked against the API, it was the MIDDLE one:\n\n  04e4e3d (oldest)  run 35526758561  artifacts=0  deploy=failure\n  5f871f7 (middle)  run 35526767814  artifacts=1  deploy=SUCCESS\n  52507a6 (newest)  run 35526774007  artifacts=0  deploy=failure   \u003c- tip of main\n\nSo a 'skip unless this commit is the tip of main' guard would have skipped 5f871f7 — the one deploy that actually published — and let 52507a6 deploy and fail anyway. Pages never updates, main still red: strictly worse than the status quo. PR #46 closed on that evidence.\n\nThe guard also aimed at the wrong failure class: it reduces the NUMBER of deploys, while the observed error is a missing artifact within a run's OWN scope. Queue depth is not what makes an artifact survive.\n\nWHAT IS STILL UNKNOWN, and what any future fix must establish FIRST: why two of three artifacts were deleted when the upload step was green in all three. Note the surviving artifact belongs to the run whose deploy SUCCEEDED, which suggests the causation may run the other way (the deploys failed because their artifacts were already gone, not the reverse).

It is the one acceptance criterion of the standalone web MVP that is not a verification gap but a MISSING FEATURE.\n\nimprovise-bck says: \"load a bundled demo .improv file, EDIT CELLS, ADD A FORMULA, save to OPFS, reload the page, verify persistence\". Everything in that sentence is now demonstrated by harness/ except adding a formula, because THE BROWSER HAS NO FORMULA ENTRY AT ALL.\n\nWHAT EXISTS: the formula PANEL has a projection (FormulaCache) and the browser receives it. What does not exist is any way to compose one — `commit-buffer formula` is in the hand-written list of text-entry commits the client cannot resolve (see improvise-e24v and the audit on improvise-g9jb), so FormulaEdit is a mode a browser can ENTER and not COMMIT. That is the dead-room shape doctrine(a_doorway_to_a_black_hole_is_worse_than_the_key) names, and `strands_the_user` currently refuses SavePrompt and ExportPrompt but NOT FormulaEdit.\n\nSO THERE ARE TWO HONEST OUTCOMES AND THEY SHOULD BE DECIDED TOGETHER:\n 1. Implement `commit-buffer formula` client-side. All its operands are in ViewState (improvise-e24v lists it under \"needs nothing added to the protocol\"), so this is the cheap half — and then the browser can add a formula and improvise-bck's criterion is met as written.\n 2. Or refuse FormulaEdit in `strands_the_user` until (1) lands, so the browser stops offering a room that swallows typing — and improvise-bck's criterion is amended to say formulas are a TUI-only affordance for now.\n\nDOING NEITHER IS THE CURRENT STATE AND IT IS THE WORST OF THE THREE: the mode opens, the user types a formula, and nothing happens.\n\nNOTE FOR WHOEVER TAKES IT: the emitted formula must go through the same add_formula path as a hand-typed one, so _Measure target handling stays identical (gotcha 7) — the same constraint improvise-vx3 worked under. And parse_formula strips pipes off a target (gotcha 34), so the client must not pre-quote.\n\n## Steps to Reproduce\n\n1. Open the document in the browser and press `F` (or `:enter-mode formula-edit`).\n2. The mode opens — `enter-mode` resolves locally in the wasm client.\n3. Type a formula and press Enter. `commit-buffer formula` has no arm in `keys.rs::step`, so `resolve` returns `Upstream`, and `Host::handle` answers `ClientFrame::Key` with an explicit empty vec.\n4.

So the aborting effect itself is counted.\n\n## Steps to Reproduce\n\n1. Fill a document to MAX_CATEGORIES (12), then add a 13th via `:add-cat X` or the `+cat` records column. The category is NOT created — `AddCategory` now sets abort_effects on refusal (PR #27) — yet `layout_version` goes 12 -\u003e 13 and `model_state.dirty` -\u003e true.\n2. Or simply `:add-cat Region` twice. `Model::add_category` returns Ok for a duplicate (types.rs:177), so this does not even abort: a pure no-op bumps both.\n\n## Consequences\n\n * EVERY OTHER CONNECTED CLIENT'S NEXT Command::Model IS REFUSED with Rejection::LayoutMoved, for a keystroke that changed nothing.\n * The browser worker's `if app.model_state.dirty { persist() }` (worker.rs:178) rewrites the whole OPFS document — and Storage is whole-document (gotcha 41).\n\n## Why this is a contradiction and not just an over-approximation\n\nThe `dirty` half IS argued as acceptable over-approximation in the comment at app.rs:617-622. The `layout_version` half is NOT — the same comment block says \"an aborted batch must not claim the effects it never ran (gotcha 21)\", which is exactly what it does. The code and its own stated rule disagree, four lines apart.\n\n## Note before fixing\n\nMoving the two bumps below the abort check closes the MAX_CATEGORIES arm but NOT the duplicate arm, because a duplicate AddCategory does not abort at all. The reachable, silent case is the duplicate. Consider bumping on observed change instead — `apply_effects` already fingerprints records for the CellData tier (gotcha 40), so \"did anything actually change\" is machinery that exists.\n","acceptance_criteria":"A refused AddCategory (MAX_CATEGORIES) and a duplicate AddCategory both leave layout_version and model_state.dirty untouched.

{"_type":"issue","id":"improvise-yqpd","title":"Transactional rollback: a frame of mutations applies whole or not at all (ADR 001 clause 4)","description":"Clause 4 of the transaction contract the user specified 2026-09-20. Clauses 1-3 landed in PR #26; this is the half that was deliberately deferred with a costed design note.\n\nTHE CONTRACT, in the user's own words: \"a sequence of commands sent to the server should assume that it's played in order from start to end and that each command sees the state after the previous command runs\", as \"a single transaction from a given base\". Four clauses:\n\n 1. A frame states ONE basis, describing the base the client composed against.        [DONE, PR #26]\n 2. Checked ONCE, before anything is applied.                                          [DONE, PR #26]\n 3. Applied IN ORDER, each command seeing what its predecessor left.                   [DONE, PR #26]\n 4. ALL OR NOTHING -- a failure leaves the document exactly as the base described.     [THIS BEAD]\n\nWHERE THE MECHANISM BELONGS: App::apply_effects, NOT Host::commands. A boundary drawn around a sequence of COMMANDS gets redrawn the day one command becomes a sequence -- and the user has said a command could eventually be \"run script\", which makes an unbounded number of mutations internally. So arity is not a property of a variant (doctrine(arity_is_not_a_property_of_a_variant)): a classifier can honestly say WHETHER a command changes the document, never HOW MANY TIMES. Design at the one mutation site and let both the frame case and the future script case use it.\n\nTHE CORE PROBLEM IN ONE LINE: abort_effects stops a batch and UNDOES NOTHING. That is an abort, not a rollback (gotcha 21), and clause 4 needs the latter. Two live examples sit in main today: a failed Save, and AddCategory refusing on MAX_CATEGORIES (PR #27).\n\nTHE DESIGN NOTE FROM PR #26, whose arguments should not be re-derived:\n * SNAPSHOT AND RESTORE, not speculative validation and not inverse effects. Speculation fails a concrete divergence argument: AcceptWizardModel calls take_built(), which CONSUMES the operand a real run would need. Inverse effects degenerate -- the general inverse of a document-replacing effect IS a snapshot -- so they do not avoid the clone, they multiply the surface by ~50.\n * THE FINGERPRINTS CANNOT BE AN UNDO LOG. The per-record XOR (gotcha 40) is a change DETECTOR, not invertible, and covers CellData only.\n * THE BOUNDARY IS THE DOCUMENT AND ITS TIERS, NOT ALL App STATE. AddCategory writes its refusal into view_state.status_msg and THEN aborts, so rolling that back would undo the explanation along with the damage.\n * WHY ROLLBACK IS SOUND AT ALL, structurally rather than by a flag: the three storage-WRITING effects (Save, SaveAs, ExportCsv) are all ViewOnly and unreachable from ModelCommand; LoadModel and ImportJsonHeadless only read. That is testable, and it becomes an acceptance criterion for any future RunScript -- a script language that can run :w breaks it.\n\nTWO ACCEPTANCE CRITERIA THAT CAME OUT OF THE P1 THE REVIEWER FOUND, and they are not obvious:\n * THE CHECKS MUST STAY BEFORE ANY APPLICATION. A frame that writes ONE RECORD TWICE is legitimate and likely -- two measures on one record IS one record -- and it works only because the second write is compared to the record's PRE-FRAME counter rather than the one its own sibling just bumped. Proved by injection: moving the record check into the apply loop fails that arm. `a_later_write_in_a_chain_still_answers_for_its_own_record` arm 3 is the guard.\n * CLAUSE 4'S ROLLBACK IS NOT THE RECORD TIER. They fail on DISJOINT frames, which is exactly why the P1 could not be deferred into this bead: rollback never fires on a frame where every command SUCCEEDS, and the lost update was a wrong answer fully applied.\n\nTHE TRADE NOBODY HAD NAMED, and the reason arm 3 exists: INTERLEAVING THE RECORD CHECK WITH THE APPLIES WOULD CLOSE THIS BEAD'S SILENCE FOR FREE. [RemoveItem(North), SetCell(North)] under interleaving is refused RecordGone instead of silently half-applying. So check-before-apply is not a free win -- it BUYS the legitimate double-write and SELLS the loud failure on a broken chain. Clause 4 must pay that back some other way, and arm 3 is what stops someone taking the trade without noticing they made it. Confirmed by two independent injections (the author's and the reviewer's, which differ in detail and agree on the direction).\n\nTHE BIGGEST AND LEAST OBVIOUS COST: ROLLING BACK THE App IS NOT ENOUGH. Host::command projects PER COMMAND, and apply_switch/apply_model adopt mirrors inline, so by the time a later command fails every session's mirror and believed grid cache have already moved. Deferring projection and relay to commit is the right fix and is also a bandwidth win -- but it changes Applied and restructures project.rs, so it is a merge-order problem as well as a size one.\n\nPROTOCOL MOVE THAT BELONGS HERE: clause 1 says the FRAME states one basis, but the wire still carries a Basis inside each Command::Model -- right when one command was one transaction. Later commands' Basis fields are currently IGNORED. Moving it to ClientFrame::Commands makes \"one basis per frame\" unrepresentable-otherwise instead of a convention.\n\nALSO FOLD IN: the `answered`/`frame_basis` classifier is a matches! whose failure direction is safe (a missed variant over-checks, never under-checks) -- make it exhaustive when the classifier returns, for the reason mutates_the_document was made exhaustive before it was deleted.\n\nESTIMATED COST from the design note: ~350-450 lines of production and as much again in tests, across app.rs, reduce.rs, project.rs, host.rs, improvise-protocol and an ADR section.\n\nINVERT `a_frame_whose_later_mutation_fails_is_not_yet_undone` when this lands. It currently characterizes the hole; all three of its assertions flip.\n","acceptance_criteria":"A ClientFrame::Commands whose later command fails leaves the document exactly as its stated basis described. The mechanism sits at or near App::apply_effects, not Host::commands, so a future multi-mutation command (RunScript) uses the same machinery. The checks stay BEFORE any application — a frame writing one record twice is legitimate and refuses itself otherwise, which a_later_write_in_a_chain_still_answers_for_its_own_record arm 3 guards. Rolling back the App is not enough: Host::command projects per command, so mirrors and believed grid caches must be deferred to commit. a_frame_whose_later_mutation_fails_is_not_yet_undone inverts.

Host::commands snapshots the document and clones the whole Sessions before the frame, and restores both on failure. Two failure signals: an effect setting abort_effects -\u003e Rejection::MutationRefused, and a command whose record no longer resolves -\u003e Rejection::ChainBroken.\n\nTHE BEAD COSTED IT WRONGLY, and that is the finding. It said interleaving the record check would buy clause 4's silence but SELL the legitimate double-write. True of the record tier's COUNTER half, false of its STRUCTURAL half -- writing a record twice cannot make it stop resolving. So the tier splits: 'does it resolve' is asked again before every mutation, 'is its counter what you claimed' stays pre-frame.

{"_type":"issue","id":"improvise-0o6x","title":"A group header first on its axis is never drawn, so a leading collapsed group has no way back","description":"Found by the independent adversarial review of PR #23, which calls it \"the most valuable thing I found that nobody named\". PRE-EXISTING and correctly characterized, but improvise-anr9 changes what it costs.\n\nTHE BEHAVIOUR: body_from(idx) starts at the first ITEM, so at row_offset == 0 a leading FrameEntry::Group is skipped. GROUPED_FRAME shows it plainly -- the group header \"Coastal\" above \"East\" is simply not drawn -- and that constant is BYTE-IDENTICAL to main, so the TUI has always behaved this way and the characterization is honest.\n\nWHY IT MATTERS MORE NOW: a COLLAPSED group that is first on its axis has NO HEADER ANYWHERE ON SCREEN, in either front end, and therefore NO WAY BACK. Its rows are hidden and the only affordance for unhiding them is the header that is not drawn.\n\nAND IT SITS EXACTLY WHERE THE WINDOWING RULE SAYS IT MUST NOT. improvise-anr9's axis_frame carries ALL headers between two in-window items specifically because \"a collapsed group's header is the only thing on screen the user can click to get its rows back\". That clause is correct and the rule is right. Position zero is the one place the rule does not reach -- not because the frame omits the header (it does not) but because body_from drops it on the way to the screen.\n\nTHE AUTHOR KNEW, WHICH IS WHY THIS IS FILED RATHER THAN REDISCOVERED: tests/grid_frame_agreement.rs deliberately orders its fixture with \"Carol\" before \"Family\" to dodge the case, and says so in a comment. It was not in the PR body and no ticket was cited, so the knowledge lived in one comment in one test.\n\nFILE THIS BEFORE ANYONE BUILDS GROUP INTERACTION IN THE BROWSER. web/app.js's group \u003cth\u003e has no click listener today and `toggle-group-under-cursor` is Upstream -- a black hole, doctrine(an_upstream_key_is_a_black_hole) -- so the affordance does not exist in the browser at all yet. The moment it does, a leading collapsed group becomes a trap: rows hidden, nothing to click.\n\nWHAT THE FIX TOUCHES, so nobody starts casually: body_from/visual_of decide what a renderer paints from a window offset. Drawing a leading header changes the row count of the painted body, which moves the exact-frame characterization buffers in src/ui/grid.rs -- so this is a deliberate re-pinning with the reason in the commit message, the same acceptance clause improvise-q0vb had. Check the interaction with the windowing rule's first clause (the nearest header ABOVE the window is carried for group_of and discarded by body_from): at offset zero there is no \"above\", so the leading header is an in-window entry that body_from is discarding, which may make the fix a one-line boundary condition rather than a redesign. Establish which before estimating.\n\nRELATED: improvise-plcx (the harness needs a grouped, multi-level fixture) is what would put this in front of a browser at all.\n\n## Steps to Reproduce\n\n1. Build a view whose row axis has a group as its FIRST entry — e.g. a category whose first item belongs to group `Coastal`.\n2. Open it in the TUI at `row_offset == 0`.\n3. The `▼ Coastal` header is not drawn at all: `body_from(0)` starts at the first ITEM and skips the leading `FrameEntry::Group`. `GROUPED_FRAME` in `src/ui/grid.rs` pins this, byte-identical to pre-anr9.\n4. Now collapse that group. Its rows disappear and its header is still not drawn — so there is nothing on screen to act on, in either front end.\n","acceptance_criteria":"A group header that is first on its axis is drawn, in the TUI and in the browser, so a collapsed group at position zero has an affordance.

It PASSED on PR #23's merged head, which means the DOM rewrite that PR shipped is genuinely browser-verified.\n\nBUT ONLY ON THE SIMPLE PATH. web/demo.improv has NO GROUPS AND ONE CATEGORY PER VISIBLE AXIS -- deliberately, per gotcha 46, because before improvise-anr9 a second category on an axis put the slash-join gap on the front page.

{"_type":"issue","id":"improvise-kc7n","title":"improvise-ws-server never checks Origin, so any page a user visits can drive their session","description":"Found by Copilot on PR #21 round 5, against a reverse-proxy recipe whose IP allow-list had itself been added two rounds earlier to close a DIFFERENT hole. Verified independently by the orchestrator: `grep -rni origin crates/improvise-ws-server/src/` returns NOTHING. The server never inspects the Origin header and accepts every handshake.\n\nTHE HOLE: a WebSocket is EXEMPT FROM THE SAME-ORIGIN POLICY -- there is no CORS preflight on a handshake. So any hostile page that an allowed user visits can open a socket to the endpoint FROM THAT USER'S OWN ALLOWED ADDRESS, and read and edit every document the server holds. That is cross-site WebSocket hijacking.\n\nWHY NETWORK CONTROLS CANNOT SEE IT: an IP allow-list, a private network, loopback binding -- all answer \"may this CLIENT reach the endpoint\", and in this attack the answer is genuinely yes. The request really does come from an allowed client; it is simply being DRIVEN by a page the user did not intend to trust. Only Origin separates the two.\n\nLOOPBACK IS NOT EXEMPT, and this is the half a documentation-only fix cannot reach. In the local pairing case there is no proxy at all, so there is nothing in front to check Origin -- and loopback is not a boundary a browser enforces. While the server runs, ANY page open in that browser can reach ws://127.0.0.1:8787. So the local development path, which is the one the project actually recommends, is the least protected.\n\nDISTINCT FROM improvise-kpnr, and both are needed. kpnr is AUTHENTICATION: who is allowed to talk to this server at all. This is CSWSH: given that someone is allowed, what may put words in their mouth. An answer to either leaves the other open.\n\nTHE FIX IS CHEAP AND SERVER-SIDE: an allow-list of permitted origins checked at the handshake, defaulting to something safe for the local case (the page's own origin, and whatever --bind implies), with a flag to widen it. Refuse the upgrade rather than accepting and ignoring.\n\nTWO THINGS TO GET RIGHT:\n * A MISSING Origin header is not the same as a disallowed one. Non-browser clients (the repo's own tests, curl, a native client) send none, and the browser always does. Decide explicitly what absent means rather than letting the match arm decide by accident.\n * PR #21 has already documented Origin filtering in the PROXY as a required companion to the network control, phrased as \"in addition to, never instead of\". When this lands, the README should say the server does it too, and the proxy line becomes defence in depth rather than the only defence.\n\nTHE GENERAL LESSON, now doctrine(who_may_connect_is_two_questions): ask of any access control whether it constrains the CLIENT or what may DRIVE the client. Three consecutive rounds of that PR reasoned about the page's capabilities and none about the attacker's.\n\n## Steps to Reproduce\n\n1. Run `improvise-ws-server` on any document.\n2. From a browser that is allowed to reach it — the user's own machine, or any address an IP allow-list permits — visit an unrelated page that opens `new WebSocket(\"ws://127.0.0.1:8787\")`.\n3. The handshake succeeds. A WebSocket is exempt from the same-origin policy, so there is no CORS preflight and `grep -rni origin crates/improvise-ws-server/src/` returns nothing — the server never looks.\n4.

So a status_msg written while a minibuffer is open is never drawn at all -- not truncated, not overwritten, simply never rendered.\n\nWHO IS AFFECTED TODAY:\n * CategoryAdd / ItemAdd: a failed `commit-buffer category` is INVISIBLE. Worse, improvise-6t3 deliberately ordered that command's effects so the add effect is emitted LAST, specifically so its failure message would WIN over the command's optimistic status. It wins a race to a surface nobody can see.\n * A failed `:w \u003cpath\u003e` from CommandMode, which is the regression Copilot found on PR #27: the abort stops the batch before ReturnToNormalUnlessMoved and clear-buffer run, so the app stays in CommandMode with the stale command in the minibuffer and the new error hidden behind it.\n\nTHE WORKAROUND ALREADY SHIPPED, and it is a workaround: CommitSave emits [ChangeMode(Normal), SaveAs] so the error lands when the bottom row is the status bar again. That works for one command and does not generalise -- every other text-entry commit has the same hole.\n\nTWO CANDIDATE FIXES, and the choice is the ticket:\n * Draw both: give the minibuffer and the status line separate rows, or render the status into the minibuffer row when a message is pending. Cheap to describe, and it changes frame geometry, which is pinned by exact-frame characterization tests (see improvise-q0vb for what that costs).\n * Make it unrepresentable: a status message set while a minibuffer is open is a bug in the CALLER, so make the caller unable to do it -- e.g. commit paths always leave the mode before reporting. That is what CommitSave now does by hand, promoted to a rule.\n\nPREFER WHICHEVER MAKES THE FAILURE LOUD. The current state is the quiet kind: the code sets a message, the test asserts the message was set, and the user never sees it.

The only control today is that it binds loopback.\n\nTHE README NOW TELLS USERS TO PUT A PUBLIC TLS PROXY IN FRONT OF IT (improvise-o8fa, per the user's ruling that the reverse proxy is the supported path to reaching a TUI-hosted document from an https origin). That instruction REMOVES THE ONLY CONTROL. TLS is confidentiality, not access control, and in a copy-pasteable recipe the two read alike.\n\nSo proxy-side auth is now LOAD-BEARING DOCUMENTATION rather than a server feature. PR #21 mitigated it -- the warning leads the section, the Caddyfile carries basic_auth marked not-optional, the --bind note now separates what loopback buys from what it does not, and the tunnel line says cloudflared/ngrok print public URLs and authenticate nothing -- but mitigation in prose is not the same as a property of the system.\n\nTHE DECISION TO MAKE, and it is a real fork rather than an oversight to correct:\n * The server grows a shared secret or token, checked at the websocket handshake. Small, and it makes the documented path safe by default rather than safe if followed.\n * Or \"auth is the proxy's job\" is the PERMANENT answer, stated in the server's own docs as a design position rather than left as an absence. Defensible -- it is what most single-binary dev servers do -- but then the README recipe is the security boundary and should say so in those words.\n\nDO NOT SPLIT THE DIFFERENCE. A token that is optional and off by default is the worst of both: it reads as a feature and defends nothing.\n\nNOTE THE GENERALISABLE PART, worth keeping whichever way this goes: DOCUMENTATION THAT INSTRUCTS AN ACTION CARRIES THAT ACTION'S CONSEQUENCES. The PR #21 section was scrupulous about one axis (build complexity, the cost of a second binary to a one-binary tool) and blind on another (exposure), and the --bind paragraph actively REASSURED the reader -- \"not reachable from anywhere else\", true of the port and false of the deployment. Neither the ticket, nor gotcha 48, nor the agent's own /code-review pass caught it; a reviewer reading the server's source did.\n\n## Rationale\n\nimprovise-ws-server has no authentication by design and `transport.rs` says so outright: anyone who can open a socket to the port can rewrite every document it serves. The only control was loopback binding — and improvise-o8fa's README now instructs users to put a public TLS proxy in front of it, which REMOVES exactly that control. TLS is confidentiality, not access control, and in a copy-pasteable recipe the two read alike.\n\nSo proxy-side auth is now load-bearing documentation rather than a property of the system. PR #21 mitigated it in prose; mitigation in prose is not the same as a mechanism.\n\n## Alternatives Considered\n\n**A shared secret or token checked at the handshake.** Small, and it makes the documented path safe by default rather than safe-if-followed. Note a URL query parameter is the one credential `new WebSocket(url)` can carry — the API sets no headers.\n\n**\"Auth is the proxy's job\" as a stated permanent position**, written into the server's own docs as a design decision rather than left as an absence.

Fixed: every mutation answers for its own records against the FRAME'S basis, with an exemption stated over a property -- a record that neither resolves nor is claimed is one the frame is creating.

Type into Profit and the write lands -- then recompute_formulas overwrites it on the next pass and the value REVERTS with no explanation.\n\nWHY IT IS NOT SIMPLY A BUG IN editable: a formula target IS a stored coordinate; the cell is a record. What makes it unwritable is not its identity but that a FORMULA OWNS IT. So the fix is a fact the projection does not currently carry -- something like \"this cell is derived\" -- and it belongs beside numeric/error on CellDisplay, which already exists precisely because the SERVER is the side that knows.\n\nCHECK THE TUI BEFORE CHANGING ANYTHING: it has the same behaviour, so whatever is decided should land in both, or the divergence becomes the new bug (gotcha 44 is what that looks like).

A fitted measure cell is evaluated at a CellKey context. In any view that aggregates over the split category -- Region on Page or None -- context.get(\"Region\") is None, and today Formula::filter falls straight through to aggregate_raw. So a categorical fit would SILENTLY DEGRADE to something else in exactly the views a pivot-table user spends most of their time in. That is a product decision about what a fit MEANS for an aggregated cell, not an emitter detail.\n\nSCOPE, once that is answered:\n * Expr::Is(Filter) evaluating to 1.0/0.0. This keeps the f64-only evaluator and avoids introducing string comparison into eval_expr. The primitive already exists in the right shape -- types.rs reads context.get(\u0026filter.category), the current cell own coordinate.\n * A grammar production plus tokenizer handling in the 1109-line parser.rs, with quoting rules for the category and item inside it (gotcha 34 -- one home, improvise_formula::quote).\n * Arms in BOTH evaluators: eval_expr and eval_expr_cached.\n * Coverage in the grammar-walking generator.\n * Thread Dataset::columns (the ColumnSpec/ColumnKind plan) into the emitter, so feature index -\u003e role is read off preprocess own plan.

It asked what a CATEGORICAL split means in a cell that aggregates over the split category. PR #25's review established the question has nothing to do with the split being categorical:\n\nA tree is fitted on individual RECORDS. A formula is evaluated at a CellKey, and in any aggregating cell evaluate_aggregated aggregates each Expr::Ref FIRST and then evaluates the IF. A linear formula survives that -- SUM(Revenue) - SUM(Cost) is SUM(Revenue - Cost) -- and a tree does not, because AGGREGATE-THEN-ROUTE IS NOT ROUTE-THEN-AGGREGATE. So EVERY fitted tree, numeric splits included, means one thing on a record row and something else one row up.\n\nIT IS NOT THEORETICAL: fit-measure Revenue on the repo's own shipped web/demo.improv is refused, naming Product=Espresso/Product=Latte. And because which features a champion picks is a property of the SEARCH, on a document with several categories the same command refuses or succeeds DEPENDING ON THE SEED. That is not a contract.\n\nWHAT THE RULING COSTS, stated plainly because it is the expensive answer and was chosen anyway: evaluate_aggregated deliberately does NOT iterate the underlying records for a formula cell -- it aggregates the refs and evaluates once. Routing per record means a formula cell must be able to ask for the records behind it and fold over them. That touches the evaluator, and it interacts with gotcha 9 (fixed-point recomputation) and with Model::formula_cache, which is where derived values live precisely so raw data and derived data stay separate.\n\nNOTE WHAT IT BUYS BESIDES CORRECTNESS: it is what a user means. A fitted rule applied to a group should say what the rule says about the members, summed -- not what the rule says about a fictional average member. The second is the thing that looks right and is wrong, which is the failure mode vx3's own ticket warned about ('a rule the user will believe').\n\nALSO NOTE: this ruling supersedes improvise-8xhy's remedy 1 (refuse at emit) as the END STATE, but not as the interim -- the refusal stays until this lands, or fit-measure silently produces the wrong number in aggregating views.\n\nTHE TWO THIRDS THIS STILL DOES NOT COVER, unchanged from the original text: col.missing means 'this record has no value for measure X', a different vocabulary; and the date sub-features (when.year, when.month) need date arithmetic improvise does not have at all.

Consistent with improvise-bpq2 (ClientMsg has no Key variant server-side) but larger than it: even a LOCAL key, one that needs no round trip, does nothing. improvise-1ey acceptance (3) is \"arrow keys move the cursor locally with no round-trip\", and nothing in the page can do it.\n\n2. A MALFORMED FRAME IS QUIET. client.on_frame(event.data) returns Result\u003c_, JsError\u003e, which wasm-bindgen turns into a THROWN EXCEPTION. It is thrown inside the message listener with no try, so it surfaces as an uncaught error in the devtools console and the following repaint() is skipped.

That is an ENCODING ARTEFACT, not an item of the document, so the emitted formula Expr::Ref fails Model::find_item_category and EVERY CELL of the fitted measure evaluates to Error(\"ref:Region=North\"). col.missing and the col.year / col.month date sub-features are in exactly the same position.\n\nSo \"fit a tree and get a working formula\" holds ONLY for a fit over numeric measures.\n\nTHE TEST THAT SHOULD HAVE CAUGHT IT WAS LYING: improvise_evaluation_matches_gp_tree_eval cannot see this, because its improvise_eval helper FABRICATES a _Measure item for every feature name, including outlook=rainy. It asserts the emitter and gp_tree::eval agree, which they do -- against a model that could not exist.

Nothing outside the crate called fitted_formula.\n\nWHY THE EMITTER AND NOT THE DATASET LAYER: dropping categorical columns before the fit is smaller, but it throws away real signal (permutation importance, and any future remedy-3 emitter) and makes the crate's halves disagree -- one-hot encoding is gp-tree's whole job. The defect is that the EMITTER spells a formula the document cannot evaluate.\n\nWHY THE CHECK ASKS THE DOCUMENT, NOT THE NAME'S SHAPE: refusing names containing '=' or matching .missing would be a syntactic proxy and a wrong one, because a measure LITERALLY NAMED Region=North is a legal document and must be accepted. The two are indistinguishable as strings; only the document can tell them apart. So it calls Model::find_item_category -- the exact precondition Expr::Ref has -- which covers .missing, the date parts, and any future sub-feature naming scheme with no second copy of preprocess's expansion rules to drift from. Both directions pinned.\n\nTHE LYING TEST IS KEPT, NOT DELETED. Quoting and threshold routing are real things improvise_evaluation_matches_gp_tree_eval checks, and outlook=rainy earns its place there as an awkward NAME TO SPELL.

The property it could not state is asserted separately against a real document: a_formula_the_emitter_accepted_evaluates_everywhere -- if fitted_formula says Ok, no cell of the target is a ref: error. That test and the refusal test are each other's check; without the accepting case the refusal could pass by refusing everything. The characterization is flipped to a_split_on_a_one_hot_feature_is_refused.\n\nREMEDY 3 IS STILL RIGHT AND IS NOT THIS TICKET -- successor filed. It is much larger than it looked: improvise has NO SCALAR COORDINATE PREDICATE (Filter gates a formula or an aggregate, it is not an Expr), it would still leave col.missing and the date parts uncovered, and it must first answer what such a predicate means where context.get(cat) is None.","dependency_count":0,"dependent_count":0,"comment_count":0}

A real latent bug in improvise-core, out of that ticket scope, worked around there by sorting.\n\nDataStore::matching_cells returns cells in HashSet iteration order, so RecordRow::group -- and therefore RECORDS-MODE ROW ORDER IN THE LIVE UI -- is not stable across processes. The same document opened twice can list its records in different orders.\n\nWHY IT MATTERS BEYOND TIDINESS:\n * gotcha 18 says IndexMap insertion order is load-bearing for persistence, and DataStore::cells is IndexMap precisely so \"records mode can display rows in the order they were entered\" (its own doc comment). The SECONDARY INDEX walk defeats that.\n * f32 accumulation is order-dependent, so anything summing over matching_cells is reproducible only within one process. improvise-4s8 had to sort before building a feature matrix or a SEEDED FIT would not reproduce across runs -- see the known-answer vectors in gp-tree, which exist because that class of drift is silent.\n * A user watching rows reorder between sessions has no way to tell whether the document changed.\n\nFIX: make matching_cells (or its callers that care) yield in the primary IndexMap order rather than the index HashSet order. Note the index exists for O(1) LOOKUP, not for iteration, so the fix is probably to intersect the index result back against the insertion-ordered primary rather than to change the index.\n\nTEST IT THE WAY THE INSTABILITY ACTUALLY SHOWS: a single-process test cannot distinguish \"sorted\" from \"hashed that way today\".

The index does lookup, the primary map does ordering.\n\nTHE BLAST RADIUS WAS LARGER THAN FILED -- five callers, and the one nobody knew about is worse than the headline:\n * view/layout.rs::group_records -- records-mode row order in the live UI (the filed case).\n * command/cmd/grid.rs::DrillIntoCell -- THE DRILL SNAPSHOT froze its record list in hash order while drill_state.pending_edits are keyed by ROW INDEX (gotcha 1). So the same drill opened in a second process keyed staged edits to DIFFERENT RECORDS: silent misdirected writes, not a cosmetic reorder. Never filed; inherits the fix.\n * eval_agg, evaluate and aggregate_raw fold f64 over the result, and f64 addition is not associative, so a formula's value could differ in the last bits between two openings of the same document. Min/Max/Count are order-free, and so is the text-unanimity rule (gotcha 7).\n * improvise-gp dataset.rs::visible_records was already sorting as a workaround (improvise-4s8). The sort is KEPT -- removing it would change the fit's row order and gp-tree's known-answer vectors are bit-level -- but its comments claimed the sort is what buys stability, which this fix makes false, so they now say it is a choice of CANONICAL order: a fit's rows should be a property of the data, not of the typing history.\n\nMEASURED, release, 18,000 cells, 2000 iterations: worst case +20% on matching_values (a sort plus one hash lookup per candidate); matching_cells is 7% FASTER, because sorted positions resolve CellKeys with better locality. Nothing became O(store) -- the alternatives (an ordered index value type, or scanning the primary) would have moved the cost onto every set or onto every query.\n\nTHE TEST SHAPE IS THE POINT: a single-process test cannot tell 'sorted' from 'hashed that way today on this machine'. So the order is compared against iter_cells -- the primary map's own order -- rather than a literal, and the_same_cells_entered_in_opposite_orders_list_in_opposite_orders builds the same logical store by two different histories and requires each to list its own.","dependency_count":0,"dependent_count":0,"comment_count":0}
{"_type":"issue","id":"improvise-rucf","title":"Read arbitrary SQLite databases as a data source","description":"SUPERSEDED BY context/adr/003-live-backed-models.md, and rewritten 2026-09-19 to match it. The original text framed this as an open choice between import-once and live-backed, and said \"READ-ONLY for now\" as though that were a scoping convenience. ADR 003 decided both, and in the opposite direction from what this ticket assumed.\n\nWHAT THE ADR DECIDED, and this ticket now means:\n\n * LIVE-BACKED, not import-once. Import-once was explicitly REJECTED as the only answer -- it makes the model a snapshot, so source changes are invisible until re-import and the data must fit in memory. The model is a view over the source and queries go to it as the user pivots.\n * READ-ONLY IS A FEATURE, not a limitation accepted reluctantly. Pointing a pivot tool at a production database and being unable to write to it is the point. No write-through, no overlay, no reconciliation.\n * THEREFORE: Model becomes a FACADE OVER A DATA SOURCE, of which today's in-RAM DataStore is one implementation and a SQL query engine is another. That is a change to what Model IS, not to where its bytes come from.\n\nSTATUS: NOT A PRIORITY, per the ADR's own header. Deferred 2026-09-19 during the whole-backlog campaign, by user ruling, together with improvise-qddo and improvise-mjy7. Nothing here outranks the browser work. It is written down so the option stays open, because several decisions made recently could foreclose it by accident.\n\nTHE THREE THINGS THAT MAKE IT TRACTABLE, from the ADR, which should shape the design rather than be discovered late:\n 1. Aggregation is ALREADY the interface and it is ALREADY SQL. apply_agg computes Sum/Avg/Min/Max/Count over a matching cell set; those are exactly SQL's aggregates. GridLayout asks for a VALUE, not for the rows behind it. The pushdown is not a translation layer to be invented.\n 2. Formula results are ALREADY separate from stored data. Evaluation is fixed-point and derived values live in Model::formula_cache, not in DataStore. Raw data is queried; derived data stays in RAM. Formulas do not become SQL.\n 3. Clients are ALREADY insulated. A client sees CellDisplays and never learns where a value came from, so live-backing and the browser deployment compose rather than compete. A browser never needs SQLite at all.\n\nTHE CONSEQUENCE NOBODY ASKED FOR, and the reason this is three tickets rather than one: a live-backed document splits into OUR configuration and THEIR data, and .improv does not distinguish them. The format grows a SOURCE SPECIFICATION where a live model would otherwise have a ## Data section, and categories become derived (SELECT DISTINCT) rather than declared. improv.pest is the single source of truth, so the grammar comes first.\n\nCHILDREN (all filed and deferred alongside this one):\n * the .improv source specification and the grammar change\n * the SQLite source implementation, native-only and feature-gated\n * projection freshness for a source an external writer can change\n\nWHAT ADR 001 DOES AND DOES NOT OWE THIS: a read-only model has no concurrent EDITS, so the basis check simply does not apply -- the guarantee is scoped to documents improvise owns, which is what it always meant. What remains is a different and smaller question, which is the freshness child.\n\nTHE MACHINERY TO EXPRESS READ-ONLY ALREADY EXISTS, built for something else: ADR 002 makes SetCell take a CellId::Record and nothing else, so a source that projects no Record ids makes a write UNCONSTRUCTIBLE by the client -- no runtime check, no error path, no read-only dialog. One design consequence for the source trait follows: writes must NOT be in the trait a query source implements, or a read-only source has to fail at runtime for a method it structurally cannot serve.\n\nTHE DEPENDENCY CONSTRAINT THAT CARRIES OVER FROM improvise-9ix: improvise-io is in the wasm bundle (the wasm job in .github/workflows/ci.yml gates it) and libsqlite3-sys does not build for wasm32-unknown-unknown under this repo's nix cc-wrapper. Native-only and feature-gated, with the wasm job passing untouched. Verify the gate rather than assuming it.\n\nWHAT THIS IS NOT: improvise-9ix, which proposed SQLite as improvise's OWN PERSISTENCE FORMAT and was declined on measurements (22% larger than .improv, 4.7x gzipped, a second implementation of the pest grammar). Reading someone else's database has no round-trip obligation and no grammar duplication.\n","notes":"\n--- SUPERSEDED IN FRAMING by ADR 003 (user, 2026-09-19) ---\nThe user chose LIVE-BACKED over import-once, and the goal is stated as: have\nTHE OPTION of essentially using improvise as a DB CLIENT.

A git worktree does NOT load that pin: .envrc is unallowed in a fresh worktree, so a process there falls through to ~/.nix-profile/bin/bd. Verified 2026-09-19 with a scrubbed DIRENV env: \"Found RC allowed 0\".

The flake pin exists to prevent this and an unallowed worktree bypasses it.\n\nWHY MANUAL ALLOW DOES NOT SUFFICE: agent worktrees are created FRESH PER DISPATCH. Allowing the ones that exist right now does not help the next one, so any manual pass is stale the moment another agent starts. Confirmed today -- allow entries were created at 16:35 and a worktree from earlier still reported allowed 0.\n\nMITIGATION 1 -- make the allow automatic. direnv allow (or an equivalent: a whitelist.prefix entry in ~/.config/direnv/direnv.toml covering the worktree root, which would cover every future worktree in one stroke and is probably the better answer) at worktree creation. Note whitelist.prefix is currently [] per direnv status.\n\nMITIGATION 2 -- assert the version rather than trust it.

ADR 001 layer 1, the correctness floor.\n\nTHE THREE THINGS THE ADR IS EMPHATIC ABOUT:\n * NO BYPASS, AND NONE DESIGNED IN. Basis has NO Default and NO public constructor -- a zero basis is not 'no claim', it is the claim that the document is fresh, which in a new App is TRUE, so a default would be forgeable. BasisCache::claim is the only door a client has and it withholds until the server has published one. There is no force flag anywhere; re_composing_against_the_republished_basis_is_accepted walks the actual force path (refused -\u003e fold the republished basis -\u003e re-compose -\u003e accepted) with nothing that skips the check.\n * STRUCTURAL AND DATA KEPT APART. RecordGone (nothing resolves, nothing to write to, nothing coherent to force -- force never creates structure) vs RecordMoved (resolves at another version, force is one keystroke). The RecordGone test deliberately brings the LAYOUT claim up to date first so the tier above cannot mask it.\n * COUNTERS ON THE App. Nothing added to ViewState; cursor_epoch went beside document_generation for the same reason.\n\nWHERE THE ADR MET THE CODE AND WAS WRONG -- the important part. ADR 001 says 'a batch carries the basis it was composed against' and NEVER SAYS HOW A CLIENT COMES TO KNOW ONE. Nothing in the projection stream carried any of the three tiers, so the check as specified was satisfiable only by a client FORGING a basis: the invariant deleted with extra steps, arriving through the front door. Closed with Projection::Basis + BasisCache -- the server publishes the two document tiers plus the write counters for the records THIS CLIENT'S GRID NAMES (exactly the set it can address a write to, per ADR 002), diffed against what that client was last told and seeded in the bootstrap. Emitted AFTER the grid updates in a batch: the counters describe cells those updates carry, so a basis arriving first would let a client claim a version for a value it had not been shown. Mirror image of gotcha 33. The ADR is amended.\n\nTHREE SMALLER UNDER-SPECIFICATIONS, all now decided:\n * 'Any record the batch touches' -- WHOSE LIST? If the client's, a client that omits a record has a FORCE BY OMISSION: the record tier skipped, no flag to remove, nothing in the message saying so. records_named is the server's own exhaustive read of the ModelCommand (one or-pattern for the 24 that name none, so a new record-writing variant fails the build), and a claim that omits a record the server knows is written gets Rejection::RecordUnstated -- its own case because 'you lost a race' and 'you were never in one' are different things to tell a user.\n * Command::SwitchView carries no basis -- it is LayoutGeometry but sits outside Command::Model, so apply_switch is unchecked. Not a corruption risk (the workbook refuses a view it does not have, and every mirror takes what was ACCEPTED), but a hole in the rule. Filed.\n * reduce_full/apply_command do not check, and that is right: the check is a property of the SESSION DOOR, not of the mutation path, because a host holding the App is the truth rather than a claimant. ui::reduce::caught_up(\u0026App, cmd) serves that host and is not a bypass -- it takes \u0026App, so nothing reachable from a wire can call it.\n\nClient side: the wasm client folds Projection::Basis and BasisCache::claim gates both compose sites, so a client with no basis composes nothing.","dependencies":[{"issue_id":"improvise-fkfg","depends_on_id":"improvise-3x3u","type":"blocks","created_at":"2026-09-19T23:27:47Z","created_by":"Edward Langley","metadata":"{}"},{"issue_id":"improvise-fkfg","depends_on_id":"improvise-5a5y","type":"blocks","created_at":"2026-09-19T23:27:44Z","created_by":"Edward Langley","metadata":"{}"}],"dependency_count":2,"dependent_count":1,"comment_count":0}

The TUI grid widget overlays staged drill edits (src/ui/grid.rs, drill_state.pending_edits) and so does App::display_value_at_cursor. SetDrillPendingEdit is ViewOnly, so Dirty is empty too. A remote client in drill mode sees neither the staged edit nor any update for it, until ApplyAndClearDrill (CellData) lands.\n\nThis is the 'second, silently divergent description' the producer's own module header warns against: three answers to what text is in a cell (GridLayout::display_text, src/ui/grid.rs, project::cell_display) and only two agree.\n\nNote the tension with the user's principle 'the model is shared, the UI isn't': pending drill edits are UNCOMMITTED writes belonging to whoever staged them (that is why gotcha 30 keeps drill_state off ViewState).

Client B sees neither the staged value nor any update for it — `SetDrillPendingEdit` is `ViewOnly`, so the `Dirty` is empty and nothing is projected — until `ApplyAndClearDrill` (`CellData`) lands.\n3. Meanwhile A's own TUI *does* show it, because `src/ui/grid.rs` overlays `drill_state.pending_edits` and so does `App::display_value_at_cursor`, while `project.rs::cell_display` resolves through `layout.records_display(row, col)`.\n\nSo there are three answers to \"what text is in this cell\" and only two agree.

That is create, attach, write, read and persist through OpfsFs -- the first real execution of a backend that had only ever been compile-checked.\n\nSo the headline risk this ticket carried is retired: OpfsFs is not fundamentally broken, and gotcha 28's sync-access-handle design holds in practice.\n\nWHAT THIS DOES NOT COVER, and why the ticket stays open at P2 rather than closing:\n * storage_contract has still never been RUN against OpfsFs. The happy path working is not the contract passing -- list semantics, delete/commit_deletes, the flat-root disagreement (improvise-2f4y), and re-attach after close are all untested.\n * One real OpfsFs-related bug was already found and fixed by reading rather than testing (attach creates and indexes the entry, so vfs::open skipped the seed -- see improvise-9x6 and the vfs test that stands in for attach). A harness would have caught it in seconds and it cost a deploy cycle instead.\n * Everything found in the browser so far was found BY A PERSON PRESSING KEYS. That is not a repeatable check.\n\nSo the argument shifts: this is no longer 'does OPFS work at all', it is 'run storage_contract against the one backend that owes it'. Fold into the Playwright harness ticket rather than treating it as a separate browser investigation.\nNARROWED 2026-09-20 by PR #24 (improvise-vvl3), not closed. Two engines of three now satisfy this ticket's acceptance criteria.\n\nWHAT IS NOW COVERED, by harness/ under Playwright on BOTH Chromium and Firefox: OpfsFs::open gets the origin root; attach acquires a sync access handle and creates the file; the full storage_contract sequence passes (write/read/replace/list-sorted/delete/read-fails/delete-twice-errors/shorter-write-truncates) at dir \"\" AND at \"docs\"; refresh lists what attach created; commit_deletes actually removes entries, verified ACROSS A RELOAD. Both of the failure points this ticket named are covered by targeted checks -- the hand-rolled keys() async-iterator walk through js_sys::Reflect (three entries, out of order) and FileSystemReadWriteOptions' 'at' handling (long write then short).\n\nIt found three real bugs doing it; see improvise-vvl3's close reason.\n\nWHAT REMAINS, and it is the whole of this bead now: SAFARI. Playwright's WebKit build provides NO OPFS AT ALL -- navigator.storage.getDirectory() itself rejects with UnknownError -- so the sync-access-handle path cannot be exercised there by this harness. The ticket's own note that 'Safari 16.4+ has synchronous handle methods, so no IndexedDB fallback' is a claim about Safari that remains UNTESTED.\n\nHOW IT IS PARKED, deliberately, rather than skipped-and-forgotten: the spec keeps the WebKit project and skips on a RUNTIME PROBE, so it starts running the day that build gains OPFS. An unexpected skip on any OTHER engine FAILS with 'that is a regression, not a known gap'.\n\nTO CLOSE THIS: either run the battery against a real Safari (a WebKit build with OPFS, or a manual run against Safari 16.4+ with the result recorded), or rule that Safari is out of scope for the browser deployment and say so -- which is a product decision, not a testing one.\nCORRECTION 2026-09-20, from the user (MDN browser-compatibility table): THE REASON RECORDED ABOVE WAS WRONG IN A WAY THAT MATTERS, even though the conclusion was right.\n\nnavigator.storage.getDirectory() has had FULL SUPPORT IN SAFARI SINCE 15.2 (released 2021-12-13) -- desktop Safari, Safari on iOS, and WebView on iOS. So 'WebKit provides no OPFS' is FALSE AS A CLAIM ABOUT SAFARI. What is true is narrower: PLAYWRIGHT'S BUNDLED WEBKIT BUILD does not expose it, and getDirectory() rejects there with UnknownError. Playwright's WebKit is not Safari, and a capability absent from that build says nothing about the browser it is derived from.\n\nKEEP THE TWO CAPABILITIES APART, because this ticket needs the second and not the first:\n * navigator.storage.getDirectory() -- the origin root. Safari 15.2+.\n * FileSystemFileHandle.createSyncAccessHandle() -- the BLOCKING read/write/truncate/flush handle that gotcha 28's whole design rests on, worker-only. That is the Safari 16.4 claim in this ticket's original text, and IT IS STILL THE UNVERIFIED ONE.\n\nSO THIS IS A TOOLING GAP, NOT A PLATFORM GAP, and that changes what closing it costs. The routes, cheapest first: a newer Playwright whose WebKit exposes OPFS; driving real Safari via safaridriver (Playwright cannot, WebDriver can); or a recorded manual run against Safari 16.4+ with the result written down. None of those needs a decision about whether Safari is in scope -- which is what the previous note implied and should not have.\n\nTHE GENERAL POINT, worth more than the correction: a capability missing from a TEST BROWSER was written down as a fact about the BROWSER. That is the same failure as doctrine(a_verified_spelling_is_not_a_verified_behaviour) pointed the other way -- an unverified ABSENCE asserted as a platform limit. The harness observed 'getDirectory() rejects here'; everything past that was inference.\n\nSTATUS CHANGED TO DEFERRED, 2026-09-20 (orchestrator, wave 2). The reasoning above is unchanged and is the reason: this is a TOOLING gap, so there is no work here anyone can do today. vvl3 landed the harness; it installs webkit and the OPFS spec skips on a RUNTIME PROBE rather than by configuration, so the day a Playwright WebKit build exposes createSyncAccessHandle the check begins running with no CI change and no edit here. Deferred rather than closed because the criterion is genuinely unverified and closing it would assert Safari coverage the harness cannot currently produce.\n\nPROCESS NOTE, recorded because it nearly cost this history: this addendum was first written with `bd update --notes`, which REPLACED all 5352 characters above rather than appending. They were recovered from the previous .beads/issues.jsonl export in git. Use `--append-notes` on a ticket that already carries reasoning -- `--notes` is a destructive overwrite and warns only after the fact.","status":"deferred","priority":2,"issue_type":"task","assignee":"wave-1","owner":"el-github@elangley.org","created_at":"2026-09-01T06:10:42Z","created_by":"Edward Langley","updated_at":"2026-09-20T17:56:26Z","started_at":"2026-09-20T05:32:36Z","labels":["area:browser"],"dependency_count":0,"dependent_count":1,"comment_count":0}

ViewState (crates/improvise-command/src/ui/app.rs:381) holds transient_keymap: Option\u003cArc\u003cKeymap\u003e\u003e. Keymap lives in improvise-command, which will depend on improvise-protocol once improvise-gxi puts reduce_full there taking \u0026Command — so a ViewState in the protocol crate carrying a Keymap is a hard dependency cycle, independent of serde.\n\nFLIP THE ARC. The transient keymap is never arbitrary: it is always the sub-keymap of a Binding::Prefix at a specific (mode, key, mods), set during dispatch and consumed on the very next keypress. There are exactly three, all flat, all on the normal keymap (g, y, Z at keymap.rs:634-642); RecordsNormal reaches them through parent fallback. So ViewState can hold the ADDRESS rather than the keymap:\n\n  - transient_keymap: Option\u003cArc\u003cKeymap\u003e\u003e\n  + transient_prefix: Option\u003c(KeyCode, KeyModifiers)\u003e\n\nand let KeymapSet — which already owns every keymap — resolve it. Both consumers can: App::handle_key has keymap_set and the mode; src/draw.rs:238 only needs binding_hints() for the which-key popup.

A ViewState in protocol carrying a Keymap is a hard cycle.

But they are a per-client concern: in the multi-client server architecture, one client scrolling or moving its cursor must not move another client's viewport.\n\nI classified all three EffectKind::ViewOnly for improvise-mae, on the grounds that projection must not broadcast them. That is the right call for projection, but it leaves a genuine inconsistency: they are the only ViewOnly effects that mutate state stored in the shared workbook, and view_only_effects_leave_shared_state_alone has to special-case them for exactly that reason (crates/improvise-command/src/ui/effect.rs).\n\nOptions:\n(a) Move selected/row_offset/col_offset out of View into ViewState, and stop persisting them. Cleanest, but changes the .improv format — a saved file would no longer restore the cursor where you left it, which may be a feature worth keeping.\n(b) Keep them in View as the saved STARTING position, and track the live per-client cursor in ViewState. The server then never projects cursor moves, and only the owning session writes back on save.\n(c) Leave as is and rely on the projection layer to filter.\n\n(b) looks right but is the most work.

{"_type":"issue","id":"improvise-907","title":"Import wizard step machine: validate early, allow going back, make the terminal step real","description":"Supersedes improvise-gfq, improvise-o1c and improvise-c6j. All three are defects in one mechanism — the WizardStep transition table in crates/improvise-io/src/import/wizard.rs plus the per-step key tables in crates/improvise-command/src/command/cmd/wizard.rs — and they interlock badly enough that fixing any one alone makes the wizard worse.\n\n(1) from improvise-gfq — build_model raises 'At least one category must be accepted' only on Enter at NameModel, the final step. An import with no category-classified field walks the user through ReviewProposals, DefineFormulas and NameModel before refusing. improvise-mzv already added an early pre-check for the opposite failure (too many categories) at the step where the user can still act; this wants the same treatment.\n\n(2) from improvise-o1c — every browsing step binds Esc to close-the-wizard and no step binds a back key. Reaching ConfigureDates or NameModel and wanting to change a field kind means Esc, losing every proposal toggle, formula and name, then restarting the import.\n\n(3) from improvise-c6j — advance() maps NameModel -\u003e Done, but the key layer never calls advance() at NameModel: Enter there runs BuildWizardModel, which closes the wizard outright. Done is reachable only from unit tests that force it. Either drop the variant and its close-on-any-key branch, or route a successful build through it as a real confirmation step.\n\nWHY TOGETHER, NOT SEPARATELY: (1) adds a gate that refuses to advance, and (2) is the observation that there is no way back once gated — shipping (1) alone strictly worsens the dead end that (2) describes. (3) decides whether the machine even has a terminal state, which determines what 'advance' means at the last step and therefore where (1)'s gate belongs. One coherent redesign of advance/previous/validate, one set of characterization tests.\n\nScope note: improvise-ych (JSON null becoming the literal item 'null') is deliberately NOT folded in — that is a data bug in build_model_with_warnings, not the step machine, and shares no code with these.\n\nSuggested shape: WizardStep::previous(), a validate(step) gate consulted by advance(), a back key (Backspace or Left) bound on every browsing step, and a decision recorded on Done.

Retraces the path actually taken rather than re-deriving the reverse of each conditional transition, so it can't drift from the forward table.

The ticket said 'only buffer name, commit command, and exit mode vary'. Tab and Backspace vary too: Tab is absent in FormulaEdit/ExportPrompt/CommandMode, duplicates Enter in CategoryAdd/ItemAdd, and runs commit-and-advance-right in Editing/RecordsEditing; CommandMode's Backspace is command-mode-backspace (exits on an empty line) rather than pop-char.

A category and a measure item can share a name, so a label cannot say which column an edit landed on. Resolved through GridLayout::record_col -\u003e RecordCol {Category, Measure, NewMeasure}.

Formula targets are computed, so there is nothing to type into them.\n- The '+' column was the user's call over two alternatives, because a blank model has no measures and wide format would otherwise leave nowhere to enter a number — that is the onboarding path pinned by the old edit_record_row_in_blank_model_persists_value test. Adding a measure is a schema change, so it applies immediately even inside a drill rather than being staged.\n\nVerified end-to-end, not just by unit tests: tests/records_wide_smoke.rs imports a real CSV, loads the .improv, and asserts the records grid is two rows with both measures side by side. My first two expectations there were wrong (measure order and row order come from the file/store, not the source CSV) — the code was right both times.\n\nSix existing tests encoded long-format behavior and were rewritten, not deleted: the two-row helper now uses two Region items rather than two measures on one, and the blank-model test drives the new '+' flow.\n\nAlso removed prune_empty's records branch, which was unreachable behind the function's own early return; filed improvise-2yk in case the early return is itself the bug.","dependency_count":0,"dependent_count":1,"comment_count":0}

There is no aggregate RenderCache on the wire.\n  * The ONE exception is the initial state transfer: a newly connected\n    client gets a Snapshot to seed from, then follows the event stream.\n    Snapshot stays bootstrap-only (wire_carries(snapshot,bootstrap_only)).\n\nConsequence for this ticket: read \"RenderCache\" as \"that widget's own cache\ntype\", and expect updates to arrive as folded projection commands rather\nthan as a rebuilt snapshot.","status":"closed","priority":2,"issue_type":"task","owner":"el-github@elangley.org","created_at":"2026-04-14T07:48:38Z","created_by":"spot","updated_at":"2026-09-19T23:40:22Z","closed_at":"2026-09-19T23:40:22Z","close_reason":"PREMISE CHECK FIRST, and the ticket as written is DEAD: RenderCache::from_app(app, subs) -\u003e RenderCache cannot be written because that aggregate does not exist and will not (improvise-rkeq, gotcha 32).

THE ROOT CRATE COULD NOT NAME A CACHE TYPE. improvise had no improvise-protocol dependency and improvise-command re-exported core/formula/io but NOT protocol, so no ratatui widget in src/ could write fn new(cache: \u0026FormulaCache). That was the hard blocker and nothing complained because nobody had tried. Fixed by re-exporting the protocol through improvise-command (and the root crate), so a host names the caches through the crate that builds them and the root takes no new dependency.\n2. THE BUILDERS RETURNED PAYLOADS, NOT CACHES. Added category_tree_of/formulas_of/view_list_of/tile_bar_of, each one line over the existing payload fn so there is no second derivation. document_projections and the tests server_truth now both derive FROM the caches, so what a widget holds and what a client folds cannot disagree.\n\nThree widgets migrated off \u0026Model/\u0026View: formula panel, view panel, tile bar. No aggregate type and no adapter type -- a caller wanting several caches calls several builders, and no widget names the seam, so deleting the temporary half is deleting call sites.\n\n6 tests, each an EQUIVALENCE between the cache and what the widget used to read off the model (plus pinned render output where drawing has layout logic).

One binary process, two halves: a 'server' holding the full App + projection layer, and a 'client' holding ViewState + render cache + ratatui widgets. Commands flow through a direct in-process channel (same shape as websocket/postMessage protocols, zero serialization overhead). The server emits projection commands back to the client's cache. Result: the ratatui path is architecturally identical to the browser paths — same reduce_full, same Command vocabulary, same cache-based rendering. Widgets stop reading \u0026App directly.","design":"Four deployment modes all share one architecture: (1) native TUI = in-process client + server with direct-call transport, (2) network thin-client = browser main thread + ws-server with websocket transport, (3) standalone web = browser main thread + worker with postMessage transport, (4) hybrid = in-process native client + server PLUS remote ws-server subscriber = native TUI with remote browser observer. Under this epic, mode (1) gets restructured to match (2) and (3). The shared pieces: reduce_full, projection layer with per-client subscriptions, Command vocabulary, render cache shape. The difference per mode is only the transport + which clients subscribe to which projection kinds. Native TUI subscribes to every projection kind because it renders everything (grid, panels, help, wizard); browser thin-client MVP subscribes to grid only. Staging: introduce a temporary RenderCache::from_app adapter, migrate widgets one at a time with the adapter bridging, split the binary and delete the adapter at the end. Every widget migration is individually landable.","notes":"Implications for other epics: (A) improvise-cqq (browser epic projection layer) gains a prerequisite on issue 1 of this epic (unified reduce_full). (B) improvise-3mm (crate-epic step 5) needs its design updated to put App in improvise-command, not improvise-tui, so reduce_full can live alongside App without pulling ratatui into ws-server or worker-server. (C) improvise-cr3 (browser DOM renderer) and issue 3 of this epic (ratatui grid cache consumer) share the RenderCache grid shape and can share the GridViewModel type — coordinate the two to avoid duplication.

Option (a) is cleaner; the abstraction issue (improvise-6mq) should probably commit to async up front if OPFS is the target. Directory layout: one root directory under OPFS for improvise, with subdirectories per purpose (autosave, user files, session state). File picker integration: when the user says 'open a file' in the browser, use the native file picker and either copy the file into OPFS or open it directly via the File System Access API's handle-based API.

NOTE: still not startable in the current dev environment — no wasm32-unknown-unknown std in the Nix toolchain and no rustup. See improvise-ywd notes.\nToolchain unblocked 2026-08-30: wasm32-unknown-unknown added to the flake (improvise-ywd), and all four bundle crates check clean. See improvise-fuj first — the two effects that still call std::fs directly need a decision on how a wasm build injects its Storage backend, which is the same decision this ticket needs.\nSYNC-VS-ASYNC RESOLVED (2026-08-30) — the abstraction does NOT need to become async, so improvise-6mq stands as built.\n\nThe DESIGN here says 'OPFS is async-only' and the NOTES say this 'may reveal a need to change the abstraction from sync to async, in which case update 6mq before starting'. That premise is incomplete. OPFS exposes two APIs:\n\n  - the promise-based one (getDirectory, getFileHandle, createWritable) — async\n  - FileSystemFileHandle.createSyncAccessHandle() -\u003e FileSystemSyncAccessHandle,\n    whose read/write/truncate/flush/close are SYNCHRONOUS, and which is available\n    ONLY inside a dedicated Web Worker. It exists precisely so wasm can do\n    blocking file I/O; it is the mechanism SQLite's WASM build uses for its OPFS\n    VFS.\n\nimprovise-9x6 puts 'the full App + command pipeline + projection layer + VFS persistence inside a browser worker'. So the persistence layer never runs on the main thread, and the sync path is available to it.\n\nShape that falls out:\n  - ASYNC, once, at worker init(): navigator.storage.getDirectory(), getFileHandle(), createSyncAccessHandle().\n  - SYNC, thereafter: the Storage impl holds the access handles; read/write are ordinary blocking calls, satisfying the existing two-method trait unchanged.\n\nThis avoids an invasive async migration through persistence::save/load and every caller, which is the outcome 6mq's Option-B choice was already hedging toward.\n\nCAVEAT: asserted from API knowledge, not tested — there is no browser here. Confirm createSyncAccessHandle availability against the target browsers (it is the weakest on Safari) before relying on it. The IndexedDB fallback this ticket already calls for is the hedge, and IndexedDB IS async-only — so the fallback, not OPFS, is what would force the async question. Decide whether the fallback is in scope before starting.\n\nPREREQUISITE: improvise-fuj — how a wasm build injects its Storage instance. App holds no Storage today; persistence::save/load hardwire PhysicalFs, and two effects bypass the trait entirely.

Native build wires PhysicalFS; later issues wire OPFS for wasm. Behavior-preserving refactor — .improv files still save and load identically on native. Foundation for the standalone web deployment and for alternative formats (sqlite, parquet) that can target any backend.","design":"Option A: adopt the vfs crate directly (vfs::VfsPath, vfs::PhysicalFS). Pros: batteries included, filesystem-path-based API, open-source implementations. Cons: sync-only; wasm backends may need async. Option B: define our own narrow Storage trait with read_bytes/write_bytes/list/stat methods, sync for native and async-wrapped for wasm. Pros: tailored to our needs. Cons: more code to maintain. Recommend starting with Option A (vfs crate) and falling back to Option B if OPFS's async-only nature forces the issue. Refactor persistence::{save_md, load_md, save_json, load_json} to take \u0026dyn Storage (or VfsPath) as the target parameter. Autosave path resolution (currently uses the dirs crate) goes behind the abstraction too — native resolves to a dirs path, wasm resolves to a fixed OPFS path.","acceptance_criteria":"(1) Persistence functions take a storage parameter rather than reading/writing files directly.

The design section recommends starting with the vfs crate. I measured the actual surface first: persistence touches the filesystem in exactly two places — write the whole document in save, read the whole document in load. autosave_path is pure path manipulation with no I/O. That does not justify a dependency plus a VfsPath abstraction. The ticket's own con for Option A is decisive: it is sync-only while OPFS, the actual wasm target, is async — adopting A would mean doing B later anyway. The trait is two methods:\n\n  fn read(\u0026self, path: \u0026Path) -\u003e Result\u003cVec\u003cu8\u003e\u003e\n  fn write(\u0026self, path: \u0026Path, bytes: \u0026[u8]) -\u003e Result\u003c()\u003e\n\nPaths are opaque document names, not a directory tree, so an OPFS or map-backed backend implements it without pretending to have directories, metadata or seeking.\n\nAC 3 IS VACUOUS: 'dirs crate usage is isolated behind a function that can be stubbed for wasm' — there is no dirs usage. dirs = \"6\" is declared at root Cargo.toml:36 and referenced nowhere under src/ or crates/*/src/. It is simply an unused dependency; noted on improvise-v9w, which already covers removing unused root deps.\n\nGzip moved from streaming File+GzEncoder to encode-then-write. The .gz suffix still selects it, which makes gzip a property of the document name rather than of the backend. physical_and_memory_backends_write_identical_bytes pins that swapping backends does not change the bytes.\n\nAC 5 (memory-backed fixture): MemoryFs, plus three persistence tests that round-trip a workbook with categories, items and data through it — no tempfile, no disk. That is the shape a browser backend plugs into.\n\nVerified beyond unit tests: import to .improv, headless add-cat against it, and the .gz path all still work through the CLI.","dependencies":[{"issue_id":"improvise-6mq","depends_on_id":"improvise-8zh","type":"blocks","created_at":"2026-04-14T00:40:08Z","created_by":"spot","metadata":"{}"}],"dependency_count":1,"dependent_count":5,"comment_count":0}

Since improvise-xks6 both deployments speak one\n    frame pair and `Host::handle` is one implementation, so the untested\n    difference is the transport alone — but that is an argument, not a run, and\n    the earlier annotation did not say so.\n\n(3) ARROW KEYS MOVE THE CURSOR LOCALLY WITH NO ROUND-TRIP — MET.\n    crates/improvise-wasm-client/tests/lockstep.rs::\n    a_locally_resolved_cursor_move_lands_where_the_host_would_put_it, plus\n    a_locally_resolved_jump_to_the_last_row_agrees_with_the_host and\n    a_client_with_no_window_answers_no_cursor_key for the edges. `resolve`\n    returns KeyOutcome::Local, which is by construction the no-host path.\n\n(4) TYPING A NUMBER + ENTER ROUND-TRIPS AND THE NEW VALUE APPEARS — MET twice,\n    at two levels. crates/improvise-wasm-client/tests/browser_round_trip.rs::\n    a_browser_client_seeds_types_a_number_and_sees_it_come_back drives the\n    client's own serialized frames through a real Host over a real App;\n    shell.spec.js's \"committing an edit sends one frame and shows the host's\n    value\" does it in Chromium and asserts the HOST's formatting (\"20,000\"),\n    not the string typed.\n\n(5) SCROLLING FETCHES CELLS FOR THE NEW VIEWPORT — NOT MET BY AN EXECUTED\n    TEST, and this is what keeps the ticket open. browser_round_trip.rs::\n    a_resize_reprojects_the_grid_at_the_new_extent covers a RESIZE, which is\n    the extent changing at a fixed offset; scrolling is the offset moving,\n    which is where gotcha 47's \"the window is the client's own fact\" and the\n    GridExtent arithmetic actually bite. web/demo.improv is too small to\n    scroll, so the fixture is the blocker: improvise-plcx, an open dependency\n    of this ticket, is what closes it.\n\n(6) RELOAD RECOVERS CLEANLY FROM CURRENT SERVER STATE — PARTIALLY MET, and\n    less than the earlier annotation claimed.

That rule lives in transport::connection alone, which keeps Host::connect total.\n\nNO KEYPRESS DOOR: the retraction arrived before one was built, so nothing had to be removed.

See improvise-ywd notes. The rest of this ticket is host-verifiable.\nCORRECTION (2026-08-29): the DESIGN section's justification for ViewState serialization is wrong, and misleading in a way that would invert the architecture.\n\nIt says: 'Server imports Command + ViewState so it can serialize wire messages and maintain a mirror of each client's view state.' The server does NOT serialize ViewState to maintain the mirror. Per improvise-cqq, it updates each session's view state 'via the shared reduce_view' — i.e. by applying the same commands the client applies. ViewState is a PROJECTION of the command stream, not a wire message. improvise-ltq (commands both directions) and improvise-m91 ('a command log is a deterministic replay') say the same.\n\nViewState: Serialize is still needed, but for exactly one reason: improvise-q08's bootstrap — 'On connect: create App + ClientSession, send initial Snapshot (full ViewState + render cache filled from current viewport)'. A client that never saw the earlier stream needs a value to fold onto. Snapshot-then-stream, not state-on-every-change.\n\nConsequences for whoever picks this up:\n- AC 3 stands, but do not build a server that ships ViewState on change. Steady-state traffic is Commands only.\n- RenderCache is local, rebuilt by applying projection commands; it needs Serialize only to ride in that same bootstrap Snapshot.\n- Because the only serialization point is bootstrap, host-only fields must NOT be in ViewState: a fresh client should not inherit a half-open import wizard, a pending prefix key, or staged drill edits.\n\nBLOCKER FOUND (2026-08-29): ViewState as it stands cannot live in this crate at all. crates/improvise-command/src/ui/app.rs:381 holds transient_keymap: Option\u003cArc\u003cKeymap\u003e\u003e. Keymap is in improvise-command, which will depend on improvise-protocol (improvise-gxi puts reduce_full there, taking \u0026Command) — a hard dependency cycle, independent of serde. wizard: Option\u003cImportWizard\u003e is a softer version (improvise-io is acyclic but outside AC 2's allowlist); drill_state and AppMode simply lack derives.\n\nProposed fix for the hard one, per the maintainer: flip the Arc. The transient keymap is always the sub-keymap of a Binding::Prefix at a specific (mode, key, mods), set during dispatch and consumed on the next keypress. ViewState can hold that address — Option\u003c(KeyCode, KeyModifiers)\u003e — and let KeymapSet, which already owns every keymap, resolve it. Both consumers can: App::handle_key has keymap_set and the mode; draw.rs only needs binding_hints() for the which-key popup. Nothing between set and consume changes the mode, since a Prefix binding emits SetTransientKeymap and nothing else.","status":"closed","priority":2,"issue_type":"feature","assignee":"Edward Langley","owner":"el-github@elangley.org","created_at":"2026-04-14T07:23:10Z","created_by":"spot","updated_at":"2026-09-01T09:03:56Z","started_at":"2026-09-01T08:55:39Z","closed_at":"2026-09-01T09:03:56Z","close_reason":"crates/improvise-protocol created.

The design section offered a per-struct method; making it required instead means a new effect cannot forget to classify itself. That matters because the failure mode is silent — a mis-declared ViewOnly edit would simply never reach connected clients. It paid off immediately: the compiler found a 58th Effect impl, SetTransientKeymap, living in command/keymap.rs rather than effect.rs, which I would have missed classifying by eye.\n\nDERIVED THE CLASSIFICATION, THEN VERIFIED IT. I extracted what each apply() body touches and reasoned about it in Prolog rather than eyeballing 58 effects. Two things that came out of it:\n\n1. The naive signal is WRONG for 21 effects. The View is stored inside model_state.workbook, so 'touches model_state' does not mean 'is a model change'. SetAxis, SetPageSelection, ToggleGroup, HideItem, ShowItem, TransposeAxes, CycleAxis, SetNumberFormat, SwitchView, ViewBack, ViewForward, CreateView, DeleteView and TogglePruneEmpty are LayoutGeometry, not CellData; Save/SaveAs/MarkDirty touch model_state for bookkeeping only and are ViewOnly. A classification done by grepping for model_state would have had the projection layer broadcasting cell updates for cursor moves.\n\n2. My own extraction was wrong twice, and I caught it by disbelieving the output rather than by luck: multi-line method chains hid workbook.model.set_cell(), and free-function helpers hid ApplyAndClearDrill's writes, so SetCell, SortData, RemoveItem and others first came out ViewOnly — obviously false. Fixed the extraction (flatten chains) and re-derived, then read the remaining suspicious ones directly.\n\nTESTS VERIFY DECLARATIONS EMPIRICALLY, not by restating them (AC 3). Rather than a table asserting kind() == what kind() returns, the tests apply each effect to a probe App and fingerprint the shared state it claims not to touch: view_only_effects_leave_shared_state_alone (16 effects, model data and view config both unchanged), cell_data_effects_actually_change_model_data, layout_geometry_effects_actually_change_view_config. Verified they bite by mislabelling SetCell as ViewOnly — the exact silent-drop bug — which fails cell_data_effects_actually_change_model_data.\n\nJUDGEMENT CALL, recorded rather than buried: SetSelected/SetRowOffset/SetColOffset write the shared, persisted View but are per-client concerns — one client scrolling must not move another's viewport — so they are ViewOnly. They are the only ViewOnly effects that mutate shared workbook state, which the test has to special-case.

Client reduce_view pattern-matches commands and applies view-slice effects; client never runs formula eval or touches Model. Server emits projections by walking the effect list after each command and computing per-viewport deltas per connected client. Effect split (model vs view) is a server-internal tag driving projection emission — never crosses the wire.

The headless import suite (tests/headless_cli.rs) does not see three faults at the CLI boundary, although the user treats that boundary as a product and context/code/cli.md section 13 states its contract. Each fault below was injected alone, and the whole workspace suite was run:\n\n1. **Every bad formula is named.** cli.md section 13 says: \"Every bad formula is named on stderr\". The headless test passes one bad and one good formula, so naming only the first bad one (the author's rival R5) is caught only by the io unit test `a_formula_that_does_not_parse_stops_the_build_and_is_named`. The fix is cheap: pass two bad `--formula`s in `an_import_formula_that_does_not_parse_refuses_names_it_and_writes_nothing`.\n2. **A CSV float measure.** With `csv_parser::number_in`'s f64 branch disabled (integers only), `1000.50` and similar measures are silently dropped. Only io unit tests failed (4 csv_parser tests and one wizard test). No headless or root integration test imports a CSV with a decimal measure and checks the value.\n3. **`:import-json` / ModelCommand::ImportJsonHeadless on a CSV.** With its CSV branch changed back to `ImportPipeline::new(Value::Array(recs.to_vec()))`, the JSON constructor, only `import_headless_refuses_records_that_collide` failed, and it failed only incidentally, because Revenue stopped being a measure. No test for this path asserts that a numeric CSV column is proposed as a Measure, or that a category's text is kept verbatim.\n\nThe wizard-only rivals R6 and R8 have no headless surface, so a unit test is the right level for them.

The hierarchical date import (improvise-8jk6.3) keeps a value the detected format cannot parse as a raw, ungrouped item in the SAME category as the generated items. So a raw value spelled like a generated item or group (`2024-01`, `2024`) merges with it. `Category::add_item_in_group` returns the existing item whichever came first, so either the raw record lands in the grouped month, or the month's later records land in an ungrouped raw item. The warning \"kept its raw value … ungrouped\" is then inaccurate.\n\nLATENT today: `detect_date_format` requires EVERY distinct value to parse, and `date_format` is written nowhere else outside tests. So no shipped input reaches the unparsed branch. The review checked this with a CSV mixing valid dates and `2024-01`: no format was detected, and the column became a plain category. It becomes live the moment a format can be chosen or detected from a sample.\n\nFix before that: refuse, fall back to Split for the column, or give raw values a namespace that cannot collide.

Citations are at gh/main b639266b.\n\nTwo writes go around `App::storage` (gotcha 2, improvise-fuj). Each calls the path-taking `persistence::save`, which always writes the real filesystem, whatever backend the host picked:\n\n1. **Autosave.** `App::autosave_if_needed` (`crates/improvise-command/src/ui/app.rs:1215-1224`, called from `src/draw.rs:93`) writes `persistence::autosave_path(path)` through `persistence::save(\u0026self.model_state.workbook, \u0026ap)`. It also runs on a wall-clock timer, with no effect and no command firing.\n2. **The headless final write.** `run_headless_commands` (`src/main.rs:442-446`) ends with `persistence::save(\u0026app.model_state.workbook, path)` rather than the `Save` effect through `app.storage`. `run_headless_import` (`src/main.rs:312`) does the same.\n\nConsequence: an `App` built with `App::with_storage(MemoryFs)` still writes to disk on autosave. So \"effects never touch std::fs\" holds only because these two are not effects. improvise-fuj's close reason says every document write goes through `App::storage`, and these two do not. Today both callers happen to use `PhysicalFs`, so nothing breaks yet. It is latent. It becomes live the moment a replay or test runs the TUI loop, or the headless loop, over `MemoryFs` (ADR 006 clause 6 proposes exactly that).\n\nFix direction: route both writes through `app.storage` (`persistence::save_to` or the `Save` effect).

None of this blocks. Clause 12 resolves the contradiction it was written for. These are details the implementer of clause 12 will hit.\n\n1. **The required regression test can pass without exercising the mapping.** It says \"Commit the unedited text\". A host or client that treats an unedited commit as a no-op (the text equals what was shown, so send nothing, or `raw == was`, so write nothing) passes both assertions without resolving any name. That is the \"a rival that fails the setup\" vacuity shape. The test should change something the user typed that is not a name, for example `Revenue - Cost` → `Revenue - Cost * 1` (Codex's original scenario: \"edit only the constant/operator\"). Then assert that the stored formula references the original item's id.\n\n2. **Which side holds the captured mapping, and what `ReplaceFormula.raw` carries on the wire, is unstated.** Clause 12 cites `OpenedCell` (client-side, in `improvise-protocol/src/client.rs`) as the model. But it also says a name not in the mapping \"is resolved against the document at commit\", which only the host can do. So either:\n   - `raw` travels as id-form text for the captured names and display text for new ones (a mixed rendering, which needs a rule for telling them apart, even though ids are globally unique); or\n   - the mapping travels with the command; or\n   - the host keeps a per-session open-editor record.\n\n   The TUI (host-local) and the browser (remote) must reach the same answer. This overlaps improvise-m56i item 6 (resolving typed names at the panel edge).\n\n3. **Clause 11 (Migration)** does not list clause 12's capture step. The Consequences bullet \"the host must resolve display names typed there back to ids\" now describes only the names that are new to the edit.\n\n4. **Minor factual drift in the revised Context paragraph.** \"The only reader is one test\" is wrong: `category.rs`'s `add_item_returns_sequential_ids` and `add_item_duplicate_returns_same_id`, and `types.rs:1385`, all read the ids. `Category::add_item` returns the id on every call, not only on the idempotent path.

These are places where the id namespace and the list of re-keyed state are incomplete:\n\n1. **Virtual views.** `view::VIRTUAL_VIEW_NAMES` is `[\"_Records\", \"_Drill\"]`. Answer 23 reserves `_` for virtual things, but clause 1 reserves only `_index`, `_dim` and `_measure`. Slugify's step 4 turns `_Drill` into `drill`, which collides with a user view named `Drill` or takes a gensym suffix. So a virtual view's id is neither reserved nor stable. They are never persisted, but they are addressed on the wire (`SwitchView`, and `_Drill` in improvise-obtu/t219).\n2. **`_Index` and `_Dim` items.** These are synthetic, such as record indices, and `_Dim` carries a column index (gotcha 1). Answer 22 makes ids unique across every kind. The ADR does not say whether these items take part. If they do, `_Index`'s `0` collides with a user item whose id is `0` (for example a display `0`).\n3. **`ViewState::active_view` and `Workbook::active_view`** are view names (`String`). Clause 6 lists cursors, expanded_cats and the view history as keyed by id, but not the active view itself.\n4. **`collapsed:` names a group.** `collapsed_line = \"collapsed: \" name \"/\" name` is category/group. Groups have no id (answer 9), but clause 2 says \"hidden and collapsed sets are keyed by ids\", and clause 5 lists `collapsed:` among references that carry the id. Only `[Coastal]` is exempted. So the collapsed set is (CategoryId, group name).\n5. **CheckedBatch's created-record exemption** (gotcha 43: a record that neither resolves nor is claimed, for `[AddItem(East), SetCell(East)]`). Clause 6 says a frame cannot address what it creates, so that exemption has no remaining producer.

ClientState::settle_relay (crates/improvise-protocol/src/client.rs) inserts a relay directly behind in_flight's head (improvise-jpba). That is right when the host processed the relay after the head frame. But a relay that another client caused can reach the host BEFORE the head frame and still arrive at this client before the head's answer. Then the host's mirror has applied relay, then head, while this client replays head, then relay. If the head is accepted and its view commands do not commute with the relay (for example SetSelected in the head and ResetCursor or SwitchView as the relay), the client and its mirror diverge. The divergence is in view state only; document data is unaffected. It is often masked because the change that emits such a relay also moves the basis, so the head is refused, and on a refusal the ordering is right. The client cannot tell the two orders apart from the stream it receives, so the fix probably needs a marker from the host, such as the count of this session's frames it had processed when it sent the relay. Codex's wording (a later local view command) does not match the code: a later unawaited frame already stays behind the relay. The real case is ordering relative to the head frame itself.

The calls are: CheckedBatch's record tier (will_be_created_by_the_frame, stale_record), broken_chain, and model_effects (unwritable -\u003e resolve_cell and aggregate_refusal, then resolve_cell again). That is five or six derivations per write, before grid_in derives the same layout once more to project it.\n\nWithout formulas each derivation is only GridLayout::with_frozen_records, which is cheap (about 2.4ms measured). But App::with_layout_of goes through project::rederived_for. When the two views' none_cats differ and the document has any formula, that CLONES THE MODEL AND RUNS recompute_formulas on every call.\n\nMEASURED (release build, Apple Silicon laptop under load, so noisy; a scratch test, discarded). Document: Region(150) x Product(120) x _Measure{Revenue, Cost}, about 18k stored Revenue cells, plus one formula (Profit = Revenue - Cost). The host sits on \"Other\", which puts Product on None. The client names \"Default\".\n- ClearCell of an empty record: best of 5 = 1.82s.\n- SetCell of a stored record, same host: 0.65s.\n- One resolve_record of the empty record alone: 227ms.\n- So about 1.1s per write is repeated derivation.\n- For contrast, with no formula the empty-record write costs the same as the host-on-Default case (about 0.24-0.34s, dominated by the pre-existing projection cost, which is improvise-swre).\n\nWho pays: the browser worker deployment most of all. There, the App's view_state is the host's own, so every client on a non-default view is \"not on the host's view\". Holding clear-cell or paste over a column of empty cells pays about 1s+ per key on a mid-size document with a formula.\n\nFix shape: derive once per command, or once per frame. For example, resolve the named view's layout once in model_effects and in the CheckedBatch record tier and pass it down. Or memoise the derived (model, layout) keyed on (view name, layout_version, document_generation), together with improvise-swre. Correctness is not in question: #281's resolution is right.

In 5 runs: 5095 twice, 5 three times. The TUI always stores 5095. With a 200 ms pause after the second Tab, the editor shows `509` and the browser stores 5095 in 5 of 5 runs.

The key REPLACES the value the TUI would have extended. #227 accepted this as a cost (\"what the user sees is what gets written\", protocol.md §3).

That shape is real, but it has a side effect. `mergeable == CONFLICTING` breaks the loop on the first poll whether the state check exists or not. So the CLOSED \"read once, not waited on\" case now holds by the loop's structure: no rival can fail it without also failing the CLOSED exit-code case.\n\nA different live closed shape does need the fix. Closed PR #46 has every check green and reports MERGEABLE/BLOCKED. A green BLOCKED rollup is waited on, and no test has that shape.\n\nRival (R8) that passes pr-watch-test.sh 52/52: exit 5 at the top of the loop for MERGED only, and exit 5 for CLOSED only after the loop breaks.

The PR body and `context/code/tui.md` say that leaving the minibuffer, \"by a successful commit or by Esc\", drops the message. For two of the eight text-entry modes that is false. `Editing` and `RecordsEditing` commit with `commit-cell-edit` and `commit-and-advance-right` (`CommitAndAdvance`). That command drops to Normal, commits, advances, and then `EnterEditAtCursor` re-enters the same `AppMode::editing()`/`records_editing()` value. So the mode after an Enter or Tab that committed and moved to ANOTHER cell equals the mode before it. The commit writes no message, so the stale one is restored beside a different cell's editor. It keeps being restored across every commit until Esc or some key writes a message.\n\nReproduced with a scratch test driving `press`, not committed. Workbook: Region{North}, measures Cost/Revenue, one cell. Keys: `R`, `o`, `5`, Tab, `7`. After `o` the status is \"Added new record row\", in RecordsEditing at (1,0). Tab commits \"5\" and moves to (1,1). \"Added new record row\" is still `status_msg` and is still drawn beside `edit: 7`. With a second `o` on the existing row, the refusal \"That record row is already here — ... fill this one in first\" survives the Tab that filled the coordinate in. At base 202e7eac (#233) both vanish on the first key.\n\nWhy the test misses it: `a_minibuffer_refusal_stands_while_the_user_fixes_it` uses only FormulaEdit. That is the one-category fixture shape. FormulaEdit's successful commit leaves the mode AND writes \"Formula added\", so the test cannot tell \"same mode\" from \"same editor session\".\n\nMode equality stands in for \"the same minibuffer session\", and a commit that re-enters the same mode breaks it. Candidate discriminators, for the author to judge: the cursor/`opened_editor` also unchanged, or a restore only when the key did not reach a commit. The second is the keymap copy the PR rightly avoided.

In records mode, project::cell_id projects every measure cell of every stored record as CellId::Record. That includes a record whose category coordinate names no item.

But `deliver` models what the host sends, which `context/code/clients.md` says is `fold`'s door. The PR comment says \"the two remaining `fold` calls model what the host sends\", but `deliver` is a third host-side call, and it is on the wrong door.\n\n   Latent today: `deliver`'s only caller (`switching_between_a_records_view_and_a_pivot_view_settles_both_ways`) sends view-only frames, so nothing is awaited and both doors settle immediately. With an awaited frame in flight, `fold_outgoing` would queue the host's relays at the BACK as the client's own frame, not directly behind the head as `settle_relay` does.

But `ui/reduce.rs::a_model_command_lands_where_its_keypress_lands` compares `format!(\"{:?}\", workbook)` across TWO Apps (`by_key` vs `by_command`).

The fix is `cell_position(key)` in place of `record_position(hash)`. Relative to gh/main this is NOT a regression, because before ciw8 nothing was refused.\n\n**Setup:** Month={Jan,Feb in Q1; Apr,May in Q2} on Row, with Q2 collapsed. `_Measure`={Revenue,Cost} on Column, with every month stored. The record {Month=Q2} is not stored, so `resolve_record` finds it only through the layout, at the Q2 fold row.\n\n**The write:** a caught-up wire `SetCell { record: RecordHash({Month=Q2}), measure: M }`. Results:\n\n| M | at bc060f67 (by record) | at 6026768c (by whole key) |\n|---|---|---|\n| Revenue (drawn: the fold cell) | refused | refused |\n| Cost, hidden in the host's view | refused | ACCEPTED, stores {Month=Q2,_Measure=Cost}=7 |\n| Bogus (no such measure) | refused | ACCEPTED, stores {Month=Q2,_Measure=Bogus}=7 |\n| None | refused | ACCEPTED, stores {Month=Q2}=7 |\n\nEach accepted write stores `Month=Q2`, a group name, as a coordinate. That is the improvise-gw18 / improvise-ciw8 shape. The cause is that `cell_position(key)` returns None for a whole key the host does not draw, and \"not drawn\" is read as \"not refused\". The fold is visible in the RECORD half, `{Month=Q2}`, and the old by-record lookup saw it there. No honest client composes these writes, since every client that sees Q2 as a fold sees an Aggregate there. They are hand-rolled or forged, but that also describes b114.\n\n**Repro** (reviewer probe, `ui::host::tests::review_217b::probe_fold_hidden_measure`, not pushed): build the fixture above with `hide_item(\"_Measure\",\"Cost\")`, then `wire`-write {Month=Q2} with measure Cost and assert `refused`.

A bool cannot express that without the client sniffing names, so carry the CategoryKind (already Serialize, and in improvise-core, which protocol depends on) in TileEntry in place of regular: bool, and let opening_tile rank Regular, then VirtualMeasure/Label, then the rest. _Measure should NOT be the primary opening: it is on an axis in every shipped document, and T Enter reads as confirm on the user's own dimension.

The usage text promises exit 4 when \"the file scan itself failed\".\n\nReproduced in a throwaway repo with two tracked files: a.md cites a known id, b.md cites a dead id.\n- Control, both readable: exit 1, names the dead id.\n- b.md chmod 000: prints `grep: context/b.md: Permission denied`, then \"all 1 cited ids resolve\", exit 0.\n- b.md deleted from the worktree but still tracked (ls-files --cached lists it): prints \"No such file or directory\", then exit 0.

Both fail loudly, not silently:\n- Run outside a git repo: `cd: null directory`, exit 1. Exit 1 is the \"dead id\" code; the contract says 4.\n- bd prints a JSON array of objects with no `id` field: jq yields `null`, so `known` is non-empty. Every cited id is then reported dead, exit 1.

The first `dd` starts at x=329, past the right edge of the 320px viewport.\n\nThe same numbers come out with gh/main's web/app.js and style.css, so #215 did not cause this. On a phone, every key description sits off-screen to the right, and the only way to read them is to scroll the overlay sideways.\n\n**Part two is new in #215.** `.help-footer` (improvise-1c5m) is `position: sticky; bottom: -1.25rem`. It sticks to the bottom only. So when the user scrolls the overlay sideways to read those descriptions, the footer scrolls away with the content. With scrollLeft at its maximum on Navigation, the footer's box is at x = -199..7, and `elementFromPoint` does not find it.

That fixes both parts. Adding `left: 0` to the footer alone fixes only part two.\n\n**How to reproduce.** Add a Playwright case at 320x568 that opens help, presses `l`, and sets `#help.scrollLeft = scrollWidth`.

The only production constructor today is the paste fallback closure in `registry.rs`, which builds it from `ctx.value_cell_key()`. That closure runs only when `parse` refuses, and `parse` refuses only an empty argument list. So nothing is broken today. But the rule \"a Resolved key came from a cursor door\" is a naming convention: any code in the crate, or outside it through the pub path, can write `PasteAt::Resolved(anything)` and skip every check.\n\nThis is the shape `Checked\u003c'_\u003e` was built to close (gotcha 43, `doctrine(an_invariant_is_made_unrepresentable_not_validated)`). The proposed fix is a private-field newtype such as `DoorKey(CellKey)`. `value_cell_key` (and `committable_cell_key` if it helps) returns it, and it is the only way to build one. Then `PasteAt::Resolved` carries a `DoorKey`, and a raw key cannot reach the unchecked arm. The guard is the signature.\n\nThe alternatives: keep the enum and make `Resolved` constructible only through a `pub(super)` fn.

On an axis with two grouped categories, pruning now changes a surviving row's group.\n\nRepro (Region outer: North in Upper; Month inner: Jan in Q1, Mar ungrouped; only North/Mar funded):\n- prune off: `[Upper, Q1, North/Jan, GroupEnd, North/Mar]`, so `row_group_for(North/Mar)` is `None`\n- prune on at #200: `[Upper, North/Mar]`, so it is `Some(Region, Upper)`\n- prune on at gh/main 98d10ca5: `[Upper, GroupEnd, North/Mar]`, so it is `None`. The layouts agree there, but Upper is a header drawn over nothing.\n\nEnumerated over 300,580 (axis x collapse x prune-mask) cases (2- and 3-level, collapsed and non-contiguous groups):\n- gh/main: 274,584 header-over-nothing, 0 membership changes.\n- #200: 0 header-over-nothing, 45,806 membership changes. Every one is this shape: the inner header was pruned, so its GroupEnd is dropped too, and the ungrouped inner item joins the outer group.\n\nUnder a flat membership model the two properties cannot both hold. In the unpruned layout the outer group has no flat members (the inner header takes over at once), so the unpruned answer is the lossy one. #200's pruned answer, that North/Mar is in Upper, is arguably the right one per level. The fix is a levelled GroupEnd, or per-level membership, so that prune on and prune off give the same answer. Choose which before fixing.\n\nA related cosmetic issue, on gh/main and #200 both: a pruned axis can end in a trailing GroupEnd (75k cases at #200, 57k on main), which `cross_product` strips from the unpruned axis.\n","notes":"USER RULING 2026-09-23: membership is per level (option A, levelled group markers), and z toggles the innermost group, the one closest to the cursor.","status":"closed","priority":3,"issue_type":"bug","assignee":"Edward Langley","owner":"el-github@elangley.org","created_at":"2026-09-23T05:53:36Z","created_by":"agent-review-191-200-198","updated_at":"2026-09-24T21:45:09Z","started_at":"2026-09-23T18:00:32Z","closed_at":"2026-09-24T21:45:09Z","close_reason":"Landed in main via #250 (reviewed; merged 2026-09-24).","comments":[{"id":"b83ba7c3-248b-5435-a96f-a222009d197f","issue_id":"improvise-e265","author":"agent-docs-wave","text":"_Posted by Claude (Opus 5.5), an agent in Edward Langley's session. This is a design write-up; nothing is implemented._\n\n# improvise-e265: design options\n\n## Where things stand (checked at gh/main 5932ad74)\n\n#200 has merged, so the drift in membership is what `main` does now. The ticket's example, run through a scratch probe (not committed) against `GridLayout::with_frozen_records`:\n\n| prune | `row_items` | `row_group_for(North/Mar)` |\n|---|---|---|\n| off | `[Upper, Q1, North/Jan, GroupEnd, North/Mar]` | `None` |\n| on | `[Upper, North/Mar]` | `Some(Region, Upper)` |\n\nNeither answer is correct at every level. North/Mar is in `Upper` at level 0 and in no `Month` group at level 1.\n\nThe cause is not really pruning. It is the flat interpretation of the markers. `Month`'s `GroupEnd` is read as \"close everything\", so `Upper`'s run ends at an inner boundary. A flat reading can't reconcile the two layouts: whichever one it matches, the other disagrees.\n\n## Who reads membership\n\n- **Core:** `GridLayout::row_group_for` / `col_group_for`, which decide what `z` (`ToggleGroupAtCursor`) collapses.\n- **Protocol:** `AxisFrame::groups`, `group_of`, `group_runs`, `group_run_heads`.\n- **TUI:** the column group band (`src/ui/grid.rs` uses `groups()` and `group_run_heads()`). Rows draw headers inline from the entries and never ask about membership.\n- **Browser:** `col_groups` in `wasm-client/src/render.rs` (uses `group_runs()`). `z` is a no-op in the browser (improvise-uln5), so it reads no row membership.\n- **Also affected:** `app.rs`'s layout fingerprint hashes `GroupEnd`; `axis_frame` (projection windowing) and `prune_axis_items` both produce marker sequences.\n\n## Options\n\n### A. Levelled markers with stack membership (recommended)\n\nEach marker says which level it belongs to:\n- core: `AxisEntry::GroupHeader { cat_name, group_name }` is unchanged, since its level is `cats.position(cat_name)`, and `GroupEnd` becomes `GroupEnd { level }`;\n- wire: `FrameGroup { level, name, collapsed }` and `FrameEntry::GroupEnd { level }`.\n\nMembership becomes a per-level stack:\n- a header at level L sets `open[L]` and clears every deeper level;\n- `GroupEnd { level: L }` clears level L and every deeper level.\n\nAn item's membership is the whole stack. The single answer `row_group_for` and `groups()` return is the **innermost open level**. For North/Jan that is still `Q1`, as today. For North/Mar it becomes `Upper`, whether or not pruning is on.\n\nPruning keeps a `GroupEnd` only when the header it closes was kept. Matching is by level, so dropping an inner pair can't close an outer run. The same trailing-`GroupEnd` strip `cross_product` applies runs after pruning too, which fixes the cosmetic issue in the ticket.\n\nCosts:\n- **Core `layout.rs`:**\n  - `expand_category` sets `level` on `GroupEnd`.\n  - `prune_axis_items`: its `pending` becomes a per-level stack, and `close_runs_of` already truncates by category.\n  - `row_group_for` / `col_group_for` walk a stack instead of finding the nearest marker.\n  - The trailing-strip becomes one helper that both `cross_product` and prune call.\n  - `run_start` is untouched.\n  - The about 12 `GroupEnd` literals in tests gain a level.\n- **`app.rs` fingerprint:** hash the level as well. One line.\n- **`project.rs::axis_frame`:** a windowing rule changes. Before the window opens it now keeps the nearest header **per level** (at most `cats.len()` entries), not just the single nearest one. Otherwise a window opening inside `North/Q1` loses `Upper`. The payload stays O(levels), not O(groups), so the reason in `command.md` (\"only the nearest, or the payload grows\") still holds with \"per level\" added.\n- **Protocol `render.rs`:**\n  - `groups()` and `group_of` keep a stack (one pass still).\n  - `group_runs` / `group_run_heads` are unchanged: they coalesce whatever `groups()` returns, and h0iv's `std::ptr::eq` rule still applies.\n  - About 13 `FrameGroup` literals and 6 `GroupEnd` literals gain a level.\n  - `body_from` (0o6x) needs checking: at the top of a windowed axis it must drop every carried header, not only one.\n- **TUI:** no code change beyond constructing the new variants. The band still shows one group per column, now the innermost open one. In the example, the band over North/Mar reads `Upper` where it now reads nothing.\n- **Browser:** the same. `col_groups` is unchanged.\n- **Wire:** a serde shape change to `FrameGroup` and `FrameEntry::GroupEnd`. Both ends are one bundle, and the cache-bust stamp covers a stale page.\n- **A side effect worth having:** `level` indexes `AxisFrame::cats`, so a client can name the category of any group. That is the piece a browser `z` would need to compose `ToggleGroup` (improvise-uln5), and it does not bring back the dead field improvise-7xyx removed. `level` is read by `groups()`, so it is live, and the category *name* comes from `cats` rather than being carried a second time.\n\nWhy the level goes on `GroupEnd` and not only on the header: in principle a stack could pair an unlevelled `GroupEnd` with its header by position. That only works if every producer emits a balanced sequence, and there are three producers: `expand_category`, `prune_axis_items` and `axis_frame`'s windowing. The last two both cut sequences. A levelled marker can be read correctly on its own, even inside a pruned or windowed fragment. Every bug in this area (gd83, u6gc, lhi4, b5zh, and now e265) has come from a producer changing marker placement, so a marker that can be read without its neighbours is the property to buy.\n\n### B. Membership stored on the item; markers derived\n\n`DataItem` carries `groups: Vec\u003cOption\u003cString\u003e\u003e`, parallel to `tuple`, filled in `expand_category`, which is the one place it is known. Membership becomes an attribute of the item, so pruning can't change it. `prune_axis_items` becomes: filter the data items, then **re-derive** the markers from the survivors with the same function expansion uses. That removes the `pending`/`run_open`/`close_runs_of` machinery, which is where the bugs listed above lived. It also removes `GroupEnd` completely, since it exists only so that membership is not inherited. Both \"header over nothing\" and \"trailing `GroupEnd`\" become impossible to represent.\n\nCosts:\n- **Core:** the largest rewrite of the three. The `DataItem` shape, `expand_category`, `prune_axis_items`, `cross_product`, `run_start`, `row_group_for`, the fingerprint, and every `AxisEntry` literal in the tests.\n- **Wire:** `FrameEntry::Item` would carry per-level groups. That is O(items × levels) in the payload where A is O(markers). Otherwise the host still has to send levelled markers, and the client-side membership walk is option A anyway. `FrameEntry::GroupEnd` would be deleted.\n- **h0iv must be argued again.** Runs can no longer be \"opened by the same header entry\" if the header is derived. The key becomes `(prefix up to L, level, group)`, which does separate `North/Q1` from `South/Q1`. But it is a new rule, and the h0iv evidence has to be re-pinned.\n- **Both front ends:** every `FrameEntry` match changes.\n\nB is the stronger invariant: an invariant made impossible to break, not one that is validated. It is also about three times the change, and its wire cost is real.\n\n### C. Membership computed before pruning (the ticket's example option)\n\nCompute `row_group_for` on the unpruned layout and carry it through pruning. This fixes the lossy flat answer, and makes it canonical: North/Mar is `None` while the user sees it under the `Upper` header row. It still needs either a second layout or an attribute carried per item. The second of those is B's cost with a worse answer, so I recommend rejecting C.\n\n### D. Keep flat membership and choose which property to lose\n\nFor example, go back to pre-#200 behaviour: `[Upper, GroupEnd, North/Mar]`, with membership stable and a header drawn over nothing. This is the cheapest option, and the ticket's enumeration shows flat membership cannot make both properties hold (274,584 cases against 45,806 at the two ends). Only acceptable as a documented leftover.\n\n## Recommendation\n\n**A.** It is the smallest type change that makes pruning on and off agree while also giving the answer that is correct at every level. It keeps h0iv's identity rule and the windowing payload bound. It also gives the browser what it would need to name a group's category for `z`.\n\nIf the user would rather pay for the invariant, B is the right shape. In that case I would take B in core first and put A's levelled markers on the wire: the host derives them, so the wire does not pay for O(items × levels).\n\n## Questions for the user\n\n1. **Which group does a row belong to?** Under A (and B), North/Mar is in `Upper`: `z` there collapses `Upper`, and the column band shows `Upper` over it. Today, unpruned, `z` there does nothing and the band is blank. Is the per-level answer the one you want?\n2. **What does `z` toggle when a row is in more than one open group?** I propose the innermost, which matches what `z` does today on North/Jan (`Q1`).\n3. **Is one column band enough?** A still paints one group per column (the innermost). One band per level would be a separate feature; I'd file it rather than fold it into this.\n\n## Proposed evidence for the fix\n\n- A property test over 2- and 3-level axes × collapse state × prune masks, the ticket's own enumeration, now as an assertion:\n  - for every item that survives pruning, the membership stack of the pruned layout equals the unpruned layout's;\n  - every header that is kept has at least one member.\n  - Rival: today's flat `prune_axis_items`. It should fail on the ticket's 45,806-case shape. A pre-#200 rival should fail the no-empty-header half instead.\n- A frame-agreement test: `AxisFrame::groups()` on the projected frame equals `GridLayout`'s per-item membership, including a window that opens inside `North/Q1`. That is the per-level windowing rule, and a nearest-single-header rival must fail it.\n","created_at":"2026-09-23T16:01:42Z"}],"dependency_count":0,"dependent_count":0,"comment_count":1}

It does not measure how many records a *built command* actually ordered in the effects the comparison compared. So it is a parallel derivation. It can pass while the comparison has lost its wide drills.\n\nRival (run, not argued): with gotcha 18 re-injected (`positions.sort_unstable()` in `DataStore::matching_positions` commented out), change the `drill-into-cell` parser in `registry.rs` from `if args.is_empty()` to `if args.len() \u003c 2`. The one-coordinate drills are then refused by `parse`, and the registry's cursor fallback builds them as a one-record cursor drill. `widest_drill` still reports 4 and the guard is silent. The law then **passed 38 of 300 runs** (~13%), the same as the pre-e1sm rate. Without the parser rival it failed 300 of 300.\n\nSo two statements are false as written:\n- `context/test-evidence/command.md`: \"The width guard reads the same argument list the comparison uses, so it cannot pass while the comparison has lost its wide drills.\"\n- `context/code/command.md`: \"That guard reads the argument list the law uses, not a copy of it, so dropping the derived drills fails it\".\n\nBoth are true for the one rival that was tried (dropping the `extend` line). They are false for a rival that keeps the list but changes what gets built from it.\n\nSuggested fix: measure the width from what was compared. For example, have `compare` record the largest `StartDrill` record count among the drill-into-cell effects it actually compared, and assert on that.

So when row0 is renamed onto row1's coordinates, row0's values overwrite row1's, even though row1 is the later row. Plain mode does the same.\n- A no-op rename (row1 Type Clothing-\u003eClothing) makes row1 write, which flips the winner to row1.

It is latent: the new scanner's output is token-identical to the old one on every .rs file in the workspace. But it contradicts the PR's stated property, that a test-only item hides nothing after it and that an item which cannot be bounded is a panic.\n\n## The shape\n\n`item_end` (crates/improvise-protocol/src/source_scan.rs) knows only two terminators: a `;` at depth 0, and the `}` closing a body. A test-only element that is separated from its siblings by a **comma** has neither. So the scan runs on to the bracket that closes the enclosing list, and the `')' | ']' | '}' if depth == 0 =\u003e return Some(k)` arm accepts that bracket as \"the item was the last expression\". Every later sibling is dropped, silently, with no panic.\n\nReproduced through `production_text`, with the output after `--- new ---`:\n\n1. **Match arm.**\n   ```\n   match k {\n       #[cfg(test)]\n       K::T =\u003e Command::TestArm(0),\n       K::P =\u003e Command::ProdArm1(1),\n   }\n   ```\n   Output: `match k { }`. So `Command::ProdArm1` is invisible to `vocabulary_is_composed`.\n2. **vec!/array element.** `vec![ #[cfg(test)] Command::TestElem(0), Command::ProdElem(1), ]` gives `vec![ ]`.\n3. **Struct-literal field.** `S { #[cfg(test)] t: .., p: Command::ProdField(1), }` gives `S { }`.\n4. **Enum variants and struct fields** behave the same: every later variant or field is dropped.\n\nSecond shape, same class. `continues()` tests `rest.starts_with(\"else\")` with no word boundary. So after a test-only block statement:\n```\n#[cfg(test)]\n{ setup(); }\nelsewhere(Command::ProdAfterBlock(1));\n```\nThe production statement `elsewhere(...)` is swallowed up to its `;`.\n\nThe old line scanner was worse on all of these: it hid to EOF. So this is not a regression; it is an unclosed part of 59q8's class.\n\n## Suggested fix\n\nRefuse rather than guess. If `item_end` reaches the enclosing close bracket having crossed a depth-0 `,`, panic with \"could not be bounded\". A plain `,` terminator would mis-bound generics such as `impl\u003cA, B\u003e` and `where A: X, B: Y`.

None of these shapes occurs in the tree today (surveyed every `#[cfg(...test...)]` in crates/*/src and src/), so this is latent. But both vocabulary guards now depend on this scanner, and two of the misreads fail silently.\n\n## Steps to Reproduce\n\nFeed each text to `source_scan::production_text` (run as a scratch test and then reverted):\n\n1. **A test-only item that ends in `];`, `);` or `};`, or a `#[cfg(test)]` statement spanning lines.**\n       impl X {\n           #[cfg(test)]\n           const NAMES: \u0026[\u0026str] = \u0026[\n               \"a\",\n           ];\n           fn prod() { let c = Command::Hidden1(1); }\n       }\n       fn after() { Command::Visible(2) }\n   Output: `impl X {` and nothing else. The first line does not end in `;`, so `strip_test_items` looks for `    }` at the attribute's indent, never finds it, and drops everything to EOF. The `#[cfg(test)] let x = foo(\\n 1,\\n);` statement form does the same.\n2. **A one-line `#[cfg(test)] use foo::bar;`.** It drops the whole rest of the file, because the attribute's own line is also the item line.\n3. **`#[cfg(all(test, not(target_arch = \"wasm32\")))]`** is kept as production, because `is_test_cfg` rejects any line containing `not(`.\n4. **Inner `#![cfg(test)]`** at the top of a module file is kept as production, because only `#[cfg(` is recognised.\n5. (Minor) C raw strings (`cr#\"…\"#`): the `r` has a word character before it, so the string is lexed as ordinary quotes and its contents leak.\n\nDirections: 1 and 2 **hide** production code. In `vocabulary_is_complete` a hidden effect is silently absent, so a new unlisted effect after such an item passes. 3 and 4 **count** test code, so in `vocabulary_is_composed` a variant composed only by such a test reads as composed.\n\nThe lexer half held against nested block comments, `r##\"…\"#…\"##`, byte strings containing `//` and `\\\"`, `'\"'`, `b'\"'`, `'\\u{27}'`, loop labels, and `'a` next to `'a'`.\n\n## Acceptance Criteria\n\n- Each shape above is a case in `source_scan`'s tests, and each fails against the current scanner.\n- `strip_test_items` either brace- or bracket-balances the item (on blanked text), or refuses (panics) on an item shape it cannot bound. It must not scan to EOF silently.\n- `is_test_cfg` evaluates the cfg predicate rather than using a substring test for `not(`, and handles `#![cfg(test)]`.\n","status":"closed","priority":3,"issue_type":"bug","assignee":"agent-wire2","owner":"el-github@elangley.org","created_at":"2026-09-23T04:16:04Z","created_by":"agent-review-172","updated_at":"2026-09-23T05:15:40Z","started_at":"2026-09-23T04:49:32Z","closed_at":"2026-09-23T05:15:40Z","close_reason":"Fixed in PR #195, merged after adversarial review at 43ba5e6.

Three documentation defects around the new completeness guard; none is a code bug, all are where the next reader looks.\n\n1. **The refusal offers the committed-loss hole as a way out.** On an unexplained loss `scripts/kb` prints `kb: restore it from HEAD and re-apply your deltas, or commit the removal.` The second option, taken on a loss nobody intended, commits the loss, and `context/code/kb-tool.md` itself says \"a bad commit of kb.pl becomes the new floor\". An agent following the message literally makes the incident permanent and invisible. The message should say commit only a removal you intended and verified, and point at `kb rm` as the way to record one.\n\n2. **The `kb` skill (`.claude/skills/kb/SKILL.md`), which AGENTS.md says to read before the first write, was not updated.** It still says \"Every write verifies the result reads back as intended and runs `kb_consistent`\", with no mention of the HEAD comparison, the ledger, exit code 3, what the new refusal means, how to recover, or that a committed loss is the new floor. The argument is only in `context/code/kb-tool.md`.\n\n3. **`kb-tool.md` states a residue hazard that does not exist, and understates the residue.** It says a SIGKILL'd `kb.pl.cand.*` \"shows as untracked in prolog-sessions/, where a git add -A would pick it up\". Ran it: SIGKILL via `KB_TEST_KILL` on a copy inside `prolog-sessions/` left `rvcopy.pl.cand.XXXX`, `.cand.XXXX.base`, `.cand.XXXX.ledger`, `.cand.XXXX.removed` and `.lock`; `git status --untracked-files=all` and `git add -A --dry-run` both show nothing, because `.gitignore:40` ignores `prolog-sessions/*`.

Until the next write, the entry excuses the loss of that exact clause by any path, which is the loss the guard exists to catch.\n\nSteps to reproduce (fixture copies, KB_FILE/KB_BASELINE, so the ledger is `$KB.removed`; the pruning logic is identical to the git-path one):\n1. copy = HEAD kb.pl. `printf \"location(cli_args,'src/main.rs',_).\\n\" \u003e rmX.pl; kb rm rmX.pl` -\u003e ledger holds `location(cli_args,'src/main.rs',A)`.\n2. Undo it the way the refusal message recommends: `cp HEAD-kb copy` (a restore; not a write, so no prune).\n3. Lose that clause by another path: `grep -v '^location(cli_args,' HEAD-kb \u003e copy`.\n4. `kb add \u003cnew doctrine\u003e` -\u003e exit 0, `complete -- baseline 809, result 809, 1 removal(s) recorded`. The loss was excused.\n- Control: the same step-3 copy with no ledger is refused, naming `location(cli_args,'src/main.rs',clap)`.\n\nThe branch-switch variant: `kb rm X` on branch A (committed or abandoned), switch to B whose HEAD has X; nothing prunes until a write, so a merge-resolution that drops X on B is excused by A's entry.\n\nThe window is narrow (one specific clause, until the next write). Pruning against the kb as read at the next write does NOT close it: by then the loss has already happened and the read kb lacks X too. One option is to record the HEAD commit and the kb stamp with each entry and discard entries whose recorded kb state is not the one being written onto (the rm's own output file is the only kb its entries may excuse); another is to key the ledger by HEAD commit so a commit or branch switch discards it.

The **whole workspace passes** (38 test binaries, 0 failures). The second test still passes because after Q1 collapses, row 0 is Apr in Q2, which is exactly what the rival also answers.

Low severity: a claim in the evidence is false, and nothing is broken at runtime.\n\n`context/test-evidence/command.md` says of `a_rolled_back_load_tells_nobody_and_puts_every_mirror_back`: \"the `document_generation` equality is checked first, so 'the frame was rejected' cannot be confused with 'the frame never got that far'\". It can be confused, because generation equality is exactly what holds when the frame never got that far. Nothing in the rollback test witnesses that the LoadModel inside the frame actually ran before the rollback. The control (`the_load_this_fixture_performs_rebases_every_client`) runs the load in a separate, single-command frame, so it proves the fixture CAN load, not that this frame did.\n\nCONFIRMED at 40b8913. Injected at the top of `Host::commands`: reject up front, before CheckedBatch, any multi-command frame containing a LoadModel. Both `a_rolled_back_load_tells_nobody_and_puts_every_mirror_back` and its sibling `a_rolled_back_load_leaves_no_ghost_view_and_no_false_status` PASS against a host that never applied the load, so neither `undo_frame` nor the mirror clone is exercised. Reverted.\n\nToday the tests are not vacuous: the evidence's `let _ = mirrors` injection fails them, because the current CheckedBatch lets the frame through to apply. But if the record tier ever moves up front for this frame, both tests go silently vacuous. Cheap fix: assert the asker's reply is `ServerFrame::Rejected(\u003cthe apply-time reason\u003e)`, a reason CheckedBatch cannot produce up front, or otherwise observe that the load was applied (e.g. a counter or a probe) before concluding anything from the rollback.\n\nOn gotcha 39's fixture warning: `host_over_a_loadable_document` does RENAME the active view (\"Loaded\").

So this is consistency, not taste.\n\nTHE TRAP, AND IT IS THE WHOLE TICKET: THE TOKEN IS NOT ALWAYS A SHA. Pages passes\n$GITHUB_SHA; a RELEASE passes the tag (improvise-oujb). Truncating blindly turns\n`v0.1.0-rc2` into `v0.1.0-r`, which is not a shorter version -- it is a WRONG one,\nand it is wrong in the one build a user is most likely to quote in a bug report.\n\nSo truncate ONLY when the token is a 40-hex SHA. That test already exists in this\nrepo: scripts/build-doc-site.mjs:21 is\n`const ref = /^[0-9a-f]{40}$/.test(token) ? token : \"main\";`\n-- SHARE the rule rather than writing a third copy of it, or at minimum point at\nthat line so the two cannot drift. Two answers to \"is this token a SHA\" is the\ndisease design-principles section 5 names.\n\nKEEP THE FULL VALUE REACHABLE. The 40-char SHA renders today only because CSS\n`text-overflow` clamps it, and the #121 agent measured that selecting the text\nstill copies the WHOLE SHA. Truncating the text loses that unless the full value\ngoes somewhere -- the `title` attribute already exists and is the obvious home,\nor a `data-` attribute. A build id you cannot copy in full is a build id that\ncannot be pasted into an issue.\n\nTHE GATE MUST MATCH WHAT IS DISPLAYED. assemble.sh:88 passes `${token}` as the\nexpected pattern; if the displayed text is truncated, that argument becomes the\ntruncated form. Getting it wrong REFUSES THE ASSEMBLY rather than shipping an\nunstamped page, so it fails safe -- but it fails loudly during a release, so get\nit right rather than relying on that. scripts/assemble-stamp.sh verifies each of\nits five pairs independently (improvise-x4wv), so a wrong pattern names itself.\n\nTEST IT AT BOTH SHAPES. scripts/assemble-stamp-test.sh is the check_the_checker\nand already runs 9 checks; a tag token and a SHA token are two cases and only one\nof them is the interesting one.

The \"useless numbers\" the user saw\nare a FORMATTING defect (improvise-e0ex): number_format defaults to \",.0\", zero\ndecimal places, so a 0.66 ratio draws as \"1\". Exact arithmetic would not change\nthat by one character. This ticket is the numerics change on its own merits, and\nthose merits are real -- which is why it is filed rather than folded in.\n\nWHY IT IS WORTH DOING INDEPENDENTLY:\n  - A spreadsheet that answers 0.1 + 0.2 with 0.30000000000000004 is wrong in the\n    way users notice and never forgive. CellValue::Number(f64) does.\n  - gotcha 18 records a REAL BUG this would have prevented: f64 addition is not\n    associative, so SUM/AVG drifted in the last bits when DataStore iteration\n    order changed. Min/Max/Count were unaffected because they are order-free.\n    EXACT RATIONALS ARE ASSOCIATIVE -- the whole class disappears rather than\n    being fixed by pinning iteration order.\n  - gotcha 17's FLOAT_EQ_EPSILON (1e-10, shared by =, != and the div/0 guard in\n    both evaluators) exists BECAUSE of binary floats. Exact arithmetic makes\n    equality exact and the epsilon unnecessary -- six uses, one constant, gone.\n\nWHAT THE TOWER MEANS HERE. Scheme's rule: exact integer -\u003e exact rational -\u003e\ninexact real, with operations preserving exactness where they can, and `/` on two\nexacts yielding an exact rational rather than a float. So Profit / Revenue is an\nexact ratio, rounded only at display. Decide explicitly what makes a value\nINEXACT and whether improvise has any such operation today (POW with a\nnon-integer exponent is the obvious candidate; there are no transcendentals).\n\nSEVEN THINGS TO ANSWER BEFORE WRITING CODE:\n  1. WHAT IS THE STORED TYPE? CellValue::Number(f64) is in improvise-core and\n     reaches everything. A new arm, a replaced arm, or a wrapper -- each has a\n     different blast radius, and CellValue is Serialize/Deserialize and crosses\n     the wire.\n  2. DENOMINATOR GROWTH. Summing thousands of exact rationals with unrelated\n     denominators is how exact arithmetic becomes slow and memory-hungry. Say\n     what bounds it. Measure at the 18,000-cell and 90,000-cell sizes gotcha 24\n     already uses, so the numbers are comparable.\n  3. THE WASM BUNDLE. improvise-core is a browser-bundle crate. A bignum\n     dependency is bundle weight on every page load; check with `cargo tree\n     --edges normal` per crate (the default output includes DEV edges and reads\n     like a leak -- see the Wasm section of repo-map).\n  4. .improv ROUND-TRIP. The format stores numbers as TEXT, so exact decimals\n     round-trip BETTER than f64 does today. That is a point in favour, but the\n     grammar and the round-trip tests must be re-read: \"1/3\" and \"0.333...\" are\n     not the same value and the format has to say which it holds.\n  5. gp-tree IS NOT IN SCOPE. It fits over f32 feature matrices and its\n     tests/scoring_known_answers.rs pins f32 BIT PATTERNS plus an RNG-call-order\n     witness (gotcha 37c). It must keep binary floats; the seam is\n     improvise-gp::dataset, and what crosses it needs stating.\n  6. WHAT DOES A THIN CLIENT SEE? CellDisplay carries text today, so a browser\n     may be unaffected -- confirm rather than assume, because if a number crosses\n     as a number, its type is a protocol change.\n  7. MIGRATION. Every existing .improv must load unchanged. Exactness is a\n     property the current format does not record, so decide what an existing\n     decimal literal BECOMES on load, and whether that is a behaviour change to\n     existing documents.\n\nTHIS IS AN ADR, NOT A TICKET, and should be one before any code -- the type\nchoice reaches improvise-core, the wire, the grammar and the browser bundle at\nonce. Note ADR 004 is being drafted for the face system, so this is 005.\n\nDO NOT START BY REPLACING f64. Start by writing down what exactness means in a\npivot table, where most cells are user-entered decimals and most operations are\nSUM.","status":"in_progress","priority":3,"issue_type":"task","assignee":"agent-adr005","owner":"el-github@elangley.org","created_at":"2026-09-22T06:11:47Z","created_by":"Edward Langley","updated_at":"2026-09-25T04:45:31Z","started_at":"2026-09-25T04:45:31Z","lease_expires_at":"2026-09-25T04:50:31Z","heartbeat_at":"2026-09-25T04:45:31Z","dependencies":[{"issue_id":"improvise-l2b8","depends_on_id":"improvise-felo","type":"parent-child","created_at":"2026-09-25T01:05:18Z","created_by":"Edward Langley","metadata":"{}"}],"comments":[{"id":"da77dcfd-15a1-5256-9e46-bb12f61582d8","issue_id":"improvise-l2b8","author":"Edward Langley","text":"Evidence from the ADR 009 agent (PR #309, examples/retraction_drift.rs, M4 Max): TODAY's eager f64 SUM over 18k cells is up to 5.8e-10 from the exact decimal sum, above FLOAT_EQ_EPSILON (1e-10) at 7 of 8 checkpoints, so IF(SUM(..) = typed value) can already be wrong.

It discriminates \"settles at all\" and \"settles against the ending layout\", but not \"settles from either mode\".\n\nThe arm is live, proved reachable in production:\n\n    records mode -\u003e apply_effects([SetAxis { \"_Index\", Axis::None }])\n      layout.is_records_mode() == false, mode was RecordsNormal\n      -\u003e settle yields AppMode::Normal\n\nOne extra case in the existing loop — seed the mode as RecordsNormal, cross OUT — closes it, and the one-way injection must then fail by name.\n\n## Gap 2 — the SwitchView path, raised by Codex and VERIFIED CORRECT\nCodex reviewed PR #91 at c186909 (round 1, the per-effect resolution) and pointed out that SwitchViewAtCursor emits [SwitchView(target), ChangeMode(Normal)]: open the view panel over a records view, select a pivot view, and round 1 would leave RecordsNormal over the pivot grid, with the inverse leaving Normal over records.\n\nRound 2 (a10e95e) moved the settle to ONE call after rebuild_layout at the end of apply_effects, so it resolves against the POST-batch layout. Verified on main at ce895ff with a throwaway probe driving a real `:` line that crosses records-ness within one batch:\n\n    start_records=true  -\u003e ended_records=false mode=Normal\n    start_records=false -\u003e ended_records=true  mode=RecordsNormal\n\nCorrect in both directions. So the behaviour Codex named is fixed.\n\nTHE GUARD IS STILL MISSING. Codex asked specifically for \"a regression that switches between records and pivot views through the view panel\", and no such test exists. The path it names is different from the one the crossing test drives (toggle-records-mode, not SwitchView), and records-ness is auto-detected from the axes (gotcha 1), so a view switch can change it.\n\n## Acceptance Criteria\n- The gap-1 case added to the existing loop; the one-way-guard injection fails by name.\n- A regression driving SwitchViewAtCursor over the view panel, records view to pivot view AND back, asserting the mode matches the grid the batch ends on.\n- Both must fail if the settle is moved back before rebuild_layout.\n","status":"closed","priority":3,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-21T11:29:18Z","created_by":"Edward Langley","updated_at":"2026-09-21T18:04:27Z","closed_at":"2026-09-21T18:04:27Z","dependency_count":0,"dependent_count":0,"comment_count":0}

Both prior copies\n— `src/ui/grid.rs`'s `group_name != prev_group` and\n`improvise-wasm-client/src/render.rs::col_groups`' `run.label == label` —\ncoalesced by name alone, so name-only is what the consolidation had to preserve\nto stay a consolidation.

That is the cost of a good consolidation\nand the reason to file rather than to note.\n\nReachability today: two categories on one axis, where the inner category has\ngroups of the same name under two different outer items — e.g. `Month` grouped\ninto `Q1` nested under `Region`, giving `North/Q1` and `South/Q1` adjacent.

I re-derived it: insert West/North/East, call sort_by_key, and both live_records() and the records-mode GridLayout reorder to East/North/West.\n\nWHY MY FIXTURE HID IT -- not the reviewer's guess (insertion already sorted), and better than that: MY FIXTURE ENTERED RECORDS MODE BY PRESSING R, and ToggleRecordsMode (command/cmd/grid.rs:476) pushes effect::SortData AS ITS FIRST EFFECT. So the store was sorted by the act of entering records mode, and the SortData I then applied was a genuine no-op. My two-record store did reorder at the DataStore level -- I checked after the review -- so the fixture, not the store, was the problem.\n\nTHE GENERAL TRAP, worth carrying: a records-mode fixture built through the key path has an already-sorted store by construction, so it cannot demonstrate anything order-sensitive. Build one by setting _Index/_Dim axes directly. That is now written into context/test-evidence/command.md under sorting_the_store_in_records_mode_invalidates_the_cursor.\n\nTHE FIX: the layout.records coords hash I removed is restored in App::view_frame, and sorting_the_store_in_records_mode_invalidates_the_cursor pins it -- asserting the row COUNT and the LABELS are both unchanged, so it is the sharp case and not a shape change wearing its name. Proved by removing the coords hash again: that test fails and NOTHING ELSE IN THE CRATE does.\n\nMY PROCESS ERROR, for the record: I concluded 'cannot reproduce' from ONE fixture without varying it, and then filed that conclusion as a finding. Removing the unverified mechanism was right; concluding the hole was not real was not. 'I could not reproduce it' and 'it does not reproduce' are different claims and I filed the second having only earned the first.\n\nClosing.","status":"closed","priority":3,"issue_type":"bug","owner":"el-github@elangley.org","created_at":"2026-09-21T03:47:15Z","created_by":"claude-agent-protocol","updated_at":"2026-09-21T04:01:44Z","closed_at":"2026-09-21T04:01:44Z","close_reason":"Closed","dependency_count":0,"dependent_count":0,"comment_count":0}

This ticket asks whether that decision is still right. It is filed rather than answered because overturning something written down deliberately is a product call.\n\nEVIDENCE, which is observed rather than argued. The convention has already failed three times inside the code that states it:\n\n1. web/app.js categoryList inlined U+25B8/U+25BE (SMALL triangles) and did not call indicator(), which returns U+25B6/U+25BC. So the browser's category panel disagreed with src/ui/category_panel.rs:78 AND with the browser's own grid group headers. Fixed on PR #55 (323677b) by calling indicator().\n2. harness/tests/widgets.spec.js asserted the divergent pair, so the obvious cure would have failed a test. Fixed in the same commit.\n3. harness/tests/pointer.spec.js had INDEPENDENTLY grown the same wrong assertions on a different branch. Three files converging on a spelling nothing compares is the failure design-principles §5 predicts, and this is it observed with data rather than argued from doctrine.\n\nStill outstanding after those fixes: web/app.js viewRow spells the active-view marker \"▶ \" as a literal, duplicating src/ui/view_panel.rs:62. The two AGREE today (both U+25B6), so it is the hazard rather than the divergence — which is exactly the state categoryList was in before it drifted.\n\nTHE DECISION. Either (a) glyphs move to the shared layer the way Axis::short_label()/initial()/glyph() already did, making the TUI and the browser draw one spelling by construction; or (b) the per-page convention is kept and the comment is corrected to say 'one spelling PER PAGE, which may differ from the TUI', which is what it actually means today. What must not persist is the current state, where the comment says 'only this spelling is the page's' (singular) while nothing enforces it.\n\nNote (a) is not free: a glyph is presentation, and design-principles §5 explicitly lists 'the mapping from a semantic value to a framework type' as what legitimately stays per-framework (AxisColor -\u003e ratatui::Color). The counter-argument is that a terminal and a DOM can both render U+25B6, so unlike a Color there is nothing to translate — which is why this is a decision and not an obvious cleanup.\n\nFound by the review agent on PR #55.","status":"open","priority":3,"issue_type":"task","owner":"el-github@elangley.org","created_at":"2026-09-20T19:50:18Z","created_by":"wave3-webui","updated_at":"2026-09-20T19:50:18Z","dependencies":[{"issue_id":"improvise-h04z","depends_on_id":"improvise-gtn7","type":"parent-child","created_at":"2026-09-25T01:05:33Z","created_by":"Edward Langley","metadata":"{}"}],"comments":[{"id":"246755fe-5911-5924-96d1-9f3403529bf8","issue_id":"improvise-h04z","author":"wave3-webui","text":"COUNTER-ARGUMENT, recorded before anyone decides — because the evidence in the\ndescription supports two readings and the incident makes only one of them salient.\n\nTHE READING THE DESCRIPTION IMPLIES: the convention is wrong, so glyphs should\nmove to the shared layer as Axis::short_label()/initial()/glyph() did.\n\nTHE OTHER READING, which fits the same evidence: the convention is RIGHT and was\nsimply not followed, because nothing enforced it. Gotcha 26's pattern is that the\n*fact* is shared and the *rendering* is local — exactly what AxisColor -\u003e\nratatui::Color does — and a third front end would rightly pick its own glyph. On\nthis reading the fix is to enforce one-home-per-front-end and to correct\nindicator()'s comment, which claims a singular spelling that nothing checks.\n\nWHAT DECIDES BETWEEN THEM, and it is a fact rather than a preference:\n`web/app.js indicator()` and `src/ui/category_panel.rs:78` ALREADY AGREED —\nU+25B6/U+25BC in both. Fixing `categoryList` to call `indicator()` made the two\nfront ends agree with NO shared-layer change at all. That is direct evidence the\nconvention was sufficient and merely unenforced.\n\nI OVERSTATED THE EVIDENCE AND WANT THAT ON THE RECORD. I wrote that three files\nconverging \"answers 'is one duplicated literal worth a protocol change' with data\ninstead of doctrine.\" It does not. The three are not three independent\nderivations:\n\n  1. categoryList BYPASSED indicator(), the one home the page already had.\n  2. widgets.spec.js asserted the page's resulting (wrong) output.\n  3. pointer.spec.js asserted the same output, on a later branch.\n\nOnly (1) chose a glyph. (2) and (3) are downstream of it — tests pinning an\nobserved rendering, which is the \"a test cements the wrong state\" failure and is\nserious, but is NOT evidence about where glyphs should live. So the three answer\n\"was the page's own one-home rule enforced?\" (no), not \"is a protocol change\nwarranted?\" — a different question from the one I claimed.\n\nTHE ONE PIECE OF EVIDENCE THAT DOES SURVIVE FOR THE PROTOCOL READING:\n`web/app.js viewRow` spells the active-view marker \"▶ \" as a literal duplicating\nsrc/ui/view_panel.rs:62. That one is NOT a bypass — there is no browser-side\nmarker helper to bypass — so it is a genuine second spelling of a fact the TUI\nalso spells, and it is the only true cross-front-end duplication left after the\ncategoryList fix. A decision should turn on that case, not on the three.\n\nWHAT MUST NOT PERSIST EITHER WAY: indicator()'s comment says \"only this spelling\nis the page's\" (singular) while nothing enforces it — which is how the bypass\nwent unnoticed. Whichever reading wins, that comment is currently false.\n\nRecorded at the orchestrator's request so the decision is made against both\nreadings.

Kept open only to record the numbers\nand the one remaining, declined, optimisation.\n\n## What it was\n\nThe stall was **not** the fold itself. It was the fold running through\n`eval_expr_cached`: at a member-record key, `Expr::Ref` looks the value up in\n`formula_cache`, which is keyed by stems with `none_cats` STRIPPED, so it could\nnever hit — and fell through to `aggregate_raw`, one poorly-narrowed scan PER\nMEMBER. An O(n^2) shape, which is why it was superlinear.\n\nThat is the same defect as the review's finding 1 (the two evaluators\ndisagreeing). Fixing the divergence — both evaluators hand the fold the same\nrecord-level `eval_expr` — fixed the cost.

At the SAME 18,050 cells, the old code cost 51 ms at a 25x361 shape and\n244 ms at 95x95 — a 4.8x spread from group COUNT alone, which is what a\nper-member `aggregate_raw` scan predicts and a constant factor does not. After\nthe fix those two shapes are 16.9-17.2 ms and 16.4-17.5 ms: indistinguishable.\n\n**The shape-dependence itself is gone**, and that is the confirmation. Scaling\nre-checked linear out to 72,200 cells (4x the cells, 4x the time, 17 -\u003e 68 ms).\nIndependently: a `SUM(Rev) - SUM(Cost)` baseline measures the same 7.1-7.8 ms as\nthe `Rev - Cost` one, so the 2.3x ratio is not an artefact of comparing against\na cheaper formula.\n\nAnyone re-measuring this must state the region/tag shape, not just the cell\ncount.\n\n## The remaining optimisation, and why it is declined\n\n`recompute_formulas` runs exactly TWO passes (measured, by counting, not\nassumed): one to compute and one to confirm stability. Raw data does not change\nwithin a recompute, so the member set per `partial` is stable across those two\npasses and could be computed once. That caps the win at ~2x on the fold's share\nof an already-linear 18 ms.\n\nDeclined as not worth it: a memo is state, and a memo keyed by anything less\nthan the whole `partial` is a second answer to \"what does this cell depend on\",\nwhich is the disease this repo names. Reopen with a document that makes 18 ms\nhurt.\n\n## What was considered and is wrong, so nobody re-proposes it\n\nRaised during the wave as a possible direction — NOT by the code review, which\ndid not propose it — and rejected on inspection:\n\n\"Fold only where folding changes the answer — if `inner` has no If and no Is,\naggregate-then-route equals route-then-aggregate\" does NOT hold. It fails for\nMIN/MAX over any non-trivial expression, and for any non-linear BinOp:\n`SUM(Rev * Cost)` is not `SUM(Rev) * SUM(Cost)`. Worse, the cheap path it would\nfall back to never computed aggregate-then-route at all — it summed the raw\nmatching cells and DISCARDED the expression. The only provably-equal case is the\nbare `Expr::Ref` fast path, which is already special-cased.\n\n## Termination, checked rather than assumed\n\nThe cached path's hand-off to `eval_expr` resets depth to MAX_EVAL_DEPTH at each\n`Agg`, while the uncached `Agg` threads its own `depth` through. That asymmetry\nis what keeps a chain bounded and must not be \"tidied\" into one rule. Verified\nterminating and cached/uncached-agreeing on: mutual reference, self-reference, a\n24-deep chain of folded formulas, nested SUM(SUM(..)), and a derived measure\ninside the fold.\n\n## Steps to Reproduce (the original stall)\n\n1. `direnv exec . cargo run --release -p improvise-core --example fold_bench`\n2.

The only provably-equal case is the bare Expr::Ref already special-cased.\n\nALSO from the re-review, and it is better evidence than the single-point improvement: the two benchmark fixtures did NOT measure the same thing before the fix and DO now.

Post-fix the spread is gone (16.9-17.2 vs 16.4-17.5). The diagnosis is confirmed by the DISAPPEARANCE OF THE SHAPE-DEPENDENCE, not merely by a smaller number.

That argument is a read, not a test, and it is the kind of read this repo has\nbeen wrong about before.\n\nTwo things to do, in order: write the test that decides whether it is reachable, and\nif it is, stop `display_value_in` consulting `drill_state` for a layout that is not\nthe host's — the drill snapshot is the host's session-local residue and a foreign\nlayout is by definition not its addressee.\n\n## Steps to Reproduce\n\nNot confirmed reachable; establishing that is the first half of the work.\n\n1. Host opens a drill and types into a cell without committing, so\n   `App::drill_state.pending_edits` is non-empty.\n2. A connected client switches to a different view (`Command::SwitchView`), so\n   `grid_in` derives a layout that is not `App::layout`.\n3. Project that client's grid and read `CellDisplay::edit_text`.\n\nIf any cell's `edit_text` comes from `pending_edits`, that is the bug: the row index\nthose edits are keyed by addresses a row in the host's drill, not in this client's\nlayout.\n","acceptance_criteria":"A test establishes whether the drill arm of display_value_in is reachable with a layout that is not App::layout. If it is, drill_state is not consulted for a foreign layout. If it is not, the test stays as the guard that says so, because the argument for unreachability is currently a read rather than a check.","status":"closed","priority":3,"issue_type":"bug","assignee":"claude-agent-cmd","owner":"el-github@elangley.org","created_at":"2026-09-20T18:33:24Z","created_by":"wave2-e-active-view","updated_at":"2026-09-21T04:43:49Z","started_at":"2026-09-21T03:27:55Z","closed_at":"2026-09-21T04:43:49Z","labels":["area:active-view"],"dependency_count":0,"dependent_count":0,"comment_count":0}

{"_type":"issue","id":"improvise-ni6k","title":"Invalidate the cursor by observing the grid frame, not by a per-effect table","description":"Successor to improvise-9mo9, proposed by the agent that implemented 9mo9 against its own work.\n\n9mo9 made ten effects call app.reset_cursor(). That is a PER-EFFECT TABLE, and this repo names that shape as the disease: 'a table of variants would be a second description of it, free to disagree' (gotcha 24, which says exactly this about why cursor_epoch is watched instead of matching on command variants).\n\nThe disagreement arrived the same day it was written: improvise-7kvw is SetPageSelection renumbering the grid under prune_empty without resetting — a gap in the new table, found immediately.\n\nThe repo's own preferred mechanism was available and not taken:\n * cursor_epoch beats matching on CycleAxis (gotcha 24)\n * document_generation beats matching on LoadModel (gotcha 39)\n * model_state.dirty beats a table of command variants (gotcha 45)\n\nAll three are observations. The equivalent here is to fingerprint the grid's FRAME (row/col identity, not contents) before and after a model batch in App::apply_effects, and reset the cursor when it moves. Then no effect declares anything, no new geometry effect can forget, and 7kvw closes as a consequence.\n\nThe agent's reason for not doing it is legitimate and recorded: the ticket and its acceptance criteria both asked for per-effect, and the change touches apply_effects, which WU-B and WU-E were editing concurrently. So this is a deliberate follow-up, not an oversight.\n\nTwo constraints any implementation must keep, both learned the hard way in 9mo9:\n 1. Reset only on SUCCESS. The epoch is document-wide, so a REFUSED add otherwise sends every client a ResetCursor for a change that never happened. The first version of 9mo9 had this bug with 1312 tests green; it was caught by reading the diff, not by a test.\n 2. The negative arm must stay tested, and there are now two arms that cannot see each other's bug: SetNumberFormat (succeeds, reshapes nothing) and a refused AddItem (reshapes nothing because it was refused).\n\n## Steps to Reproduce\n\nNot a defect report — 7kvw is the concrete instance. This ticket is the structural fix that makes instances like it unrepresentable.","acceptance_criteria":"reset_cursor is driven by an observation — the grid's frame fingerprinted before and after a model batch, reset when it moves — rather than by each effect declaring it. improvise-7kvw and any sibling gap close as a consequence rather than needing their own fix. The negative arm still holds: a batch that reshapes nothing invalidates nothing, including a REFUSED one.","notes":"THE GAP IS SIX COMMANDS WIDE, NOT ONE (enumerated 2026-09-20, at a6258f7, after\nthe adversarial review of PR #49). improvise-9mo9 closed the ten it named and\nfiled improvise-7kvw as \"the residual\". That framing undersells this ticket:\n7kvw is one instance of a class, and here is the whole class.\n\nEffects that call app.reset_cursor() -- twelve: AddCategory, AddItem,\nAddItemInGroup, CycleAxis, HideItem, RemoveCategory, RemoveItem, SetAxis,\nShowItem, ToggleGroup, TogglePruneEmpty, TransposeAxes.\n\nModelCommand variants that CAN renumber the grid and do NOT reset:\n  - SetPageSelection -- under prune_empty, a different page prunes different\n    rows (improvise-7kvw, already filed)\n  - AddFormula / RemoveFormula -- a formula target is a _Measure item, so it is\n    a column whenever _Measure is on Row or Column\n  - SetCell / ClearCell -- under prune_empty, writing into or clearing the last\n    value in a row makes that row appear or disappear\n  - CleanEmptyRecords -- drops records, so rows, in records mode\n  - SortData -- reorders records, which renumbers EVERY row in records mode\n    while changing neither the row count nor any label\n\nSortData is the sharpest of these and the best argument for observing rather\nthan declaring: it is the one case where row_count() and the label set are both\nunchanged and every position still names a different record. A guard written as\n\"did the shape change\" would miss it; the frame fingerprint would not, because\nthe fingerprint is over row_items/col_items, which carry the labels IN ORDER.\n\nWHY THIS WAS NOT FIXED PER-EFFECT TOO: the F1 round of the review showed the\ncost. Six accepted-but-no-op commands each needed their own change-detector\n(SetAxis comparing try_axis_of, HideItem/ShowItem comparing is_hidden,\nAddItem/RemoveItem via a shared has_item, RemoveCategory via category().is_some())\n-- six chances to get it wrong, three of which had already been taken across two\nrounds. Adding six more effects to that table doubles the surface without\nchanging the shape of the mistake.\n\nTHE COST THAT STILL HAS TO BE MEASURED BEFORE DOING THIS: a per-batch frame\nfingerprint sits on the keypress path, and benches/grid_projection.rs (landed in\nPR #49) measures a whole-grid pass at ~150ms for 18,000 cells. A fingerprint over\nrow_items/col_items is much cheaper than grid_of -- it hashes labels, it does not\nevaluate cells -- but \"much cheaper\" is the kind of claim that ticket's own\nacceptance criterion exists to refuse. Benchmark it against the same fixture\nsizes before landing.\nTWO MORE INSTANCES, from the adversarial review of PR #49 (2026-09-20).\n\n(1) TogglePruneEmpty on a grid with nothing empty resets the cursor and bumps the\nepoch. It is the only residual no-op that is ORDINARY USE rather than a bad name,\nand it is ONE KEYSTROKE in the TUI. It is not guarded per-effect because guarding\nit means computing the pruned layout to find out whether pruning would change\nanything -- i.e. building the very frame this ticket proposes fingerprinting. It\nis the cleanest single argument for doing this the observed way.\n\n(2) HideItem / RemoveItem on a category parked on Axis::None: the data changes,\nrow_items/col_items do not. A frame fingerprint is right by construction here,\nwhere a per-effect predicate would need its own notion of \"visible axis\" -- and\nPage/Filter make that a judgement call (gotcha 27), not a lookup.\n\nWHAT PR #49 DID FIX PER-EFFECT, so this ticket is not inheriting it: SetAxis on an\nunregistered category, HideItem/ShowItem on a name the grid never drew,\nToggleGroup on a nonexistent group, and AddItem/AddItemInGroup/RemoveItem via an\neffective-items comparison across the mutation (which is itself an observation,\nand the reason it is correct in both directions at once).\n\nThe AddItem case is worth carrying into this ticket's design: the predicate that\nfailed read `category.items` while _Measure's effective items are explicit UNION\nformula targets (gotcha 7). Any fingerprint must be taken over what the GRID\ndraws, never over what the model stores.\nDONE except SortData, which is improvise-gfvj.\n\nClosed as a consequence: improvise-7kvw (SetPageSelection under prune_empty), pinned by paging_across_a_prune_that_drops_a_row_invalidates_the_cursor. Note 7kvw is claimed by claude-agent-cmd with an expired lease -- if that agent also patched it per-effect, the two changes overlap and the per-effect guard should go, since the observation covers it.\n\nAlso covered, with no arm of their own: AddFormula/RemoveFormula (added to the shared reshaping_commands table), TogglePruneEmpty on a grid with nothing empty, and HideItem/RemoveItem on a category parked on Axis::None -- all three now answer by observation.\n\nCost measured as the AC required, benches/reshape_observation.rs: +13% to +20% on one SetCell batch at 400 / 9.6k / 18k / 90k cells. The batch is dominated by rebuild_layout and recompute_formulas.\n\nTHE DESIGN POINT WORTH CARRYING: the cursor's question and layout_version's question are NOT the same, so this is a second observation beside view_shape and not a replacement for it. AddCategory of an empty category moves no row or column but does change the coordinates a client's CellKey hangs off. Unifying them broke tests in both directions -- that is how the distinction was found, not by reasoning.","status":"closed","priority":3,"issue_type":"task","assignee":"claude-agent-protocol","owner":"el-github@elangley.org","created_at":"2026-09-20T18:23:51Z","created_by":"orchestrator","updated_at":"2026-09-21T03:47:21Z","started_at":"2026-09-21T03:28:18Z","closed_at":"2026-09-21T03:47:21Z","close_reason":"Closed","dependency_count":0,"dependent_count":0,"comment_count":0}

The principle answers it: the DEFAULT belongs to the DOCUMENT and a SWITCH belongs to the CLIENT, and they are different things that happen to name the same kind of value.\n\n - Workbook::active_view is the document's default -- what a freshly connected client opens, and what .improv writes as `Initial View`.

THEY PREDATE THE RECORDS COLUMNS. `improvise-2zq`'s `+cat` column landed in\n   `6a929c1` on 2026-09-19 and `improvise-c5v`'s `+` measure column with it —\n   five months after the recording. `drill.cast` shows records/drill mode as it\n   was BEFORE either column existed, so the drill cast is the one that is\n   materially wrong rather than merely old. What still matches: the tile bar's\n   `short_label()` vocabulary (`Row`/`Col`/`Pag`/`·`) and the mode line, both\n   verified against `crates/improvise-core/src/view/axis.rs`.\n\n2. THEY CARRY THE RECORDER'S SHELL PROMPT. Every cast opens and closes on\n   `(0) Mac:edwlan--s059 ~gf/u/edwlan/improvise git-\u003emain \u003cdate\u003e`, which is a\n   local hostname and home-directory path on a public page. `formulas.cast` and\n   `import.cast` are the worst: the visible opening frame is the prompt, not\n   improvise.\n\n3. THE GEOMETRY DISAGREES WITH ITS OWN TICKET. improvise-d4w's description says\n   \"Terminal: 100x30\" and improvise-e61 repeats it as the player config; the\n   cast headers say `\"width\": 120, \"height\": 37`. The landing page therefore\n   sets `cols: 120, rows: 37`, because a 30-row player clips the bottom seven\n   rows of a 37-row cast — which is exactly where the tile bar and status line\n   are. The recordings also use only about twenty of the thirty-seven rows, so\n   each player is roughly half empty.\n\nRE-RECORDING FIXES ALL THREE AT ONCE and needs nothing built: record at the\ngeometry the page declares, from a clean prompt (`env -i` or a bare `PS1`), and\nmake the drill cast show the `+cat`/`+` columns that now exist. Then update the\n`cols`/`rows` in `docs/index.html` if the new geometry differs.\n\n## Steps to Reproduce\n\n1. `python3 -m http.server 8123 --directory docs` and open\n   `http://127.0.0.1:8123/index.html`.\n2. Press play on \"Formulas over dimensions\": the first frame is a zsh prompt\n   reading `Mac:edwlan--s059 ~gf/u/edwlan/improvise`.\n3. Press play on \"Drill into an aggregate\" and watch the records grid: there is\n   no `+cat` column and no `+` measure column, both of which the current build\n   draws (`crates/improvise-core/src/view/layout.rs::records_columns`).\n4. `head -c 200 docs/casts/pivot.cast` — the header says `\"width\": 120,\n   \"height\": 37`, not the 100x30 improvise-d4w's description claims.","acceptance_criteria":"All four casts under docs/casts/ are re-recorded from a clean prompt (no hostname or home-directory path in any frame), at a geometry matching docs/index.html's cols/rows, with drill.cast showing the current records grid including the +cat and + measure columns. docs/index.html's player config is updated if the new geometry differs.

This is a WRONG answer to no divergence at all, on a routine navigation keypress. Calling them the same over-approximation flattens a distinction another test in the same PR was making.\n\nPRE-EXISTING: true since improvise-gv9r's fix (0b298d7) made dirtiness come off the effect kind, and invisible until now only because ApplyAndClearDrill's tests drove apply directly, bypassing apply_effects -- they measured the effect in isolation rather than the path production takes.\n\nTHE OBVIOUS FIX IS UNAVAILABLE, stated so the next person does not try: Effect::kind(\u0026self) takes no App, so the classification CANNOT be state-dependent. An effect cannot declare \"Model if there is a drill to commit, ViewOnly otherwise\".\n\nTHE CHEAP FIX ALREADY EXISTS IN THE CODEBASE: apply_effects already computes a per-record XOR fingerprint diff whenever a batch declares a CellData effect (gotcha 40), so \"did any record actually change\" is ALREADY KNOWN at the end of the batch.

COPILOT IS RIGHT AND THIS IS A REAL BUG.\n\nAxisFrame::group_of answers with the NEAREST PRECEDING GROUP HEADER, which is not the same as the item's group membership. GridLayout::expand_category emits a header on ENTERING a group and NO BOUNDARY ON LEAVING ONE, so an ungrouped item appearing after a grouped run inherits that group -- in the frame, and in the span the TUI paints.\n\nIT IS GridLayout's BUG, NOT THE FRAME'S. The TUI has painted that span forever; improvise-anr9 faithfully reproduced the existing rule when it moved the frame onto the wire, which is what a migration should do (doctrine(characterization_survives_the_move)). What changed is that the rule is now WRITTEN DOWN and therefore visible.\n\nWHY IT WAS RIGHT TO DECLINE IT THERE: fixing it means changing AxisEntry in improvise-core to carry a group-end boundary, and changing what the TUI DRAWS -- which would destroy `the_whole_frame_is_unchanged`, the exact-buffer characterization that was PR #23's only evidence the migration changed nothing. Same shape as improvise-q0vb's decline on PR #12: a finding that is correct and still wrong to fix in that PR, because of what it costs in evidence.\n\nTHE EVIDENCE IS ALREADY WRITTEN AND IT IS THE GOOD KIND. `the_two_front_ends_draw_the_same_column_header` asserts the WRONG answer as the current one -- Q1 spanning all six columns -- with THE CORRECTED EXPECTATION `[(Some(\"Q1\"), 4), (None, 2)]` WRITTEN BESIDE IT. So the day someone fixes AxisEntry, that test fails and the fix is one line of expectation away, with the intended answer already argued. The doc on group_of states the rule and names the defect.\n\nWHAT THE FIX COSTS, so nobody starts it casually: AxisEntry is in improvise-core; a group-end boundary changes the shape every consumer of row_items/col_items walks; and the characterization buffers in src/ui/grid.rs move, which means re-pinning them deliberately and saying so in the commit, exactly as improvise-q0vb's acceptance clause required.\n\n## Steps to Reproduce\n\n1.

Ask `AxisFrame::group_of(idx)` for the ungrouped item's index.\n3. It answers with the nearest preceding header, so the ungrouped item is reported as a member of the group that ended before it.\n4. The TUI paints the same span, so this is `GridLayout`'s rule faithfully reproduced rather than a frame defect.\n\n`the_two_front_ends_draw_the_same_column_header` in `tests/grid_frame_agreement.rs` asserts the wrong answer as the current one, with `THE_MEMBERSHIP_CORRECT_SPANS` and an `assert_ne!` beside it that starts failing the day this is fixed.\n","acceptance_criteria":"AxisEntry carries a group-end boundary, so group_of answers membership rather than nearest-preceding. THE_MEMBERSHIP_CORRECT_SPANS in tests/grid_frame_agreement.rs becomes the asserted value and its assert_ne! is removed.

{"_type":"issue","id":"improvise-xps8","title":"The handshake watchdog overwrites a genuine mid-session disconnect eight seconds later","description":"Found by improvise-vvl3's harness (PR #24) -- the first time web/app.js had ever been executed -- and it is a THIRD bug in the same family, distinct from both of the ones already dealt with.\n\nTHE SEQUENCE, measured rather than argued:\n\n  open-then-close:  connecting... -\u003e connected -\u003e disconnected\n                    -\u003e \"accepted the connection but sent no document\"   \u003c- EIGHT SECONDS LATER\n\nOn the open-then-close arm the handshake watchdog IS armed (armWatchdog runs after transport.ready, which resolves on `open`), and nothing disarms it when the socket later closes. So a genuine mid-session disconnect is correctly reported, and then silently replaced eight seconds later by a message that is FALSE -- the peer did not fail to answer a handshake, it answered and then went away.\n\nIT SURVIVES improvise-taxx'S FIX, confirmed rather than assumed: the harness simulated the `opened` flag and the assertion still fails. taxx distinguishes never-connected from was-connected-and-dropped in the CLOSE listener; this is the TIMER overwriting whatever that listener concluded. Different mechanism, same surface.\n\nIT IS THE SAME CLASS AS THE BUG setShellFailure ALREADY FIXED -- a timer firing later and replacing a more precise message (gotcha 48, \"a watchdog must be disarmed, not pre-empted\"). The fix for that one cleared the timer on a LOUD failure. This arm is not loud: a close after a successful open is an ordinary event, not an error, so it never reaches setShellFailure. The likely answer is that the close listener disarms the watchdog on the opened path, since once a socket has opened the handshake question is settled either way -- but check whether any path legitimately wants the watchdog to survive a close before assuming it.\n\nWHY IT IS NOT A CI GUARD, and this is the part worth reading before trying to test it: the harness shipped an assertion for this and HAD TO REMOVE IT. It reproduces on macOS/Chromium and NOT on the GitHub runner, because the trigger is the ORDER of error/close/timer on the host's network stack. A Playwright test.fail is green when the bug is present and red when it is absent, so an expected-failure whose trigger is platform-dependent does not merely flake -- IT INVERTS CI'S MEANING, and it failed the browser job twice reporting \"expected to fail, but passed\". See doctrine(an_expected_failure_must_not_be_platform_dependent). The measurement and the reproduction recipe are recorded in harness/tests/shell.spec.js.\n\nNOTE THE SAME CAVEAT NOW APPLIES TO improvise-taxx: its bug is also only locally reproducible, which is why the two assertions the fix owed could not be shipped as guards either. The fix is still right; it is the pinning that is unavailable.\n\n## Steps to Reproduce\n\n1. Serve the page and point it at a reachable `improvise-ws-server` so the socket actually OPENS (status reads `connected`).\n2. Stop the server, or otherwise drop the connection mid-session.\n3. The status line reads `disconnected` — correct.\n4. Wait eight seconds. The handshake watchdog, armed on open and never disarmed, replaces it with `accepted the connection but sent no document`.\n\nReproduces on macOS/Chromium. Does NOT reproduce on the GitHub runner, where the order of `error`/`close`/timer on the host's network stack differs — which is why this cannot be pinned as a CI guard. See `harness/tests/shell.spec.js` for the measurement.\n","acceptance_criteria":"The watchdog is disarmed when a socket that had OPENED subsequently closes, so a mid-session disconnect keeps its own message. The never-opened path is unchanged (the watchdog is the only thing that speaks there).

A European CSV therefore imports with days and months SWAPPED, silently, and every date in the column is wrong in a way that still looks like a date.\n\nWHY IT IS TRACKED RATHER THAN FIXED, and this is the argument that carried:\n * The import wizard SHOWS the detected format and lets the user override it, so the mis-read is visible at the point of import to a user who looks. That is the same argument detect_short_year_format already recorded for its own guess.\n * Changing the default to day-first only moves which half of the world imports silently wrong.\n * The honest fix is larger than the heuristic: an AMBIGUOUS column should surface its ambiguity rather than resolve it, which changes the analyzer's return shape (FieldProposal) and the wizard step that displays it. Worth doing deliberately, not as a patch.\n\nWHAT PR #22 DID CHANGE, and it is why this is now a stable known limit rather than a lottery: analyze_records used to iterate a HashSet, so the ten samples detect_date_format looks at were a DIFFERENT TEN EVERY RUN -- meaning a column whose eleventh value rules out %m/%d/%Y detected a different format run to run. Same CSV, same import, different dates. That is fixed (first-seen order, invariant(analyzer_first_seen_order)), so the heuristic is now WRONG DETERMINISTICALLY, which is the precondition for anyone being able to reason about it at all.\n\nPINNED BY: an_ambiguous_date_is_read_american_first, whose doc-comment states plainly that this silently mis-reads a European CSV, with the day-first reading asserted to parse so the test is a statement about AMBIGUITY rather than about parsing. a_day_first_only_value_settles_the_ambiguity is the discriminating other arm.\n\nSTILL TRUE AND UNCHANGED: the ten-sample window itself.

That is already better than improvise-8tk left it -- the user is told where to go. The open question is whether being told is enough, or whether the vim reflex should just land somewhere useful.\n\nTHE OBSTACLE THE ORIGINAL TICKET NAMED, still true: CmdContext does not expose file_path, so a Cmd cannot currently decide \"is there a path\" at execute time. Adding the field is small; note improvise-2ud is separately proposing that CmdContext borrow the ModelState/ViewState slices rather than copying ~20 individual fields, which would make this free. Coordinate rather than adding a 21st copied field ahead of it.\n\nTHE CONSTRAINT PR #27 ESTABLISHED, and it must be respected by whatever lands here: the prompt is SESSION-LOCAL and was deliberately kept in the COMMAND layer rather than routed through effect::Save. Save is becoming a wire command (improvise-368h), and a prompt is addressed to precisely one session -- routing it through the effect would open a prompt on a host nobody asked, which is gotcha 38's argument for keeping AcceptWizardModel off the wire. So: a Cmd that inspects the path and emits a mode change, never an effect that decides to prompt.\n\nDECIDE ALSO what ZZ means once the prompt is open. ZZ is \"save and quit\"; if the prompt commits to SaveAs and the batch was aborted, the quit is gone. Should committing the path then quit? That is a second composition and the answer is not obviously yes -- a user who hit ZZ, got a prompt, and typed a path plausibly wants to leave, but making the prompt's Enter mode-dependent is the kind of hidden state improvise-ct5 just declined to add for `i`.\n\n## Decision\n\nOpen.

So under a fold-relative diff the ColWidths that a reframe currently carries becomes REDUNDANT and is suppressed. The client is correct either way; what changes is whether the reframe still SENDS the widths.\n\nTHE REASON IT WAS NOT SPENT IN PR #20: that assertion is gotcha 33(c)'s standing evidence -- it is the test that catches \"a late ColWidths put the mismatch straight back\".

The ADR calls this \"worth doing first regardless of the eventual shape\"; the user's ruling is that the whole direction waits, so it waits as a unit rather than landing a seam with nothing on the other side of it.\n\nTHE WORK IS UNCHANGED: introduce a source trait in improvise-core and make the current in-RAM DataStore AN implementation of it rather than THE implementation. No behaviour change -- doctrine(characterization_survives_the_move) applies and the existing tests must carry across unchanged in meaning.\n\nTODAY Model holds a DataStore directly and a Workbook loads ENTIRE; there is no partial-load path anywhere in the tree (verified while declining improvise-9ix). So \"where cell values come from\" is not a seam, it is an assumption spread across GridLayout, evaluation and persistence.\n\nWHAT ADR 003 ADDS TO THE ORIGINAL FRAMING, and it is the part worth re-reading before starting:\n\n * AGGREGATION IS THE INTERFACE, AND IT IS ALREADY SQL. apply_agg computes Sum/Avg/Min/Max/Count over a matching cell set -- exactly SQL's aggregates -- and GridLayout asks for a VALUE, not for the rows behind it. Shape the trait around \"give me the aggregate for this coordinate set\", never around \"give me the cells\": shaping it around cells forecloses pushdown, which is the entire point of the eventual live source.\n\n * WRITES MUST NOT BE IN THE TRAIT. This is new since the original text and it is a real constraint. If writing were in the trait a query source implements, a read-only source would have to FAIL AT RUNTIME for a method it structurally cannot serve. Keep reads and aggregates in the trait every source implements; let writing be a capability only the owned in-RAM implementation has. Read-only then becomes UNREPRESENTABLE rather than enforced -- the same discipline as CellId (ADR 002) and doctrine(an_invariant_is_made_unrepresentable_not_validated).\n\n * FORMULAS DO NOT MOVE. Evaluation is fixed-point and derived values live in Model::formula_cache, not in DataStore, so the split is clean: raw data is queried, derived data stays in RAM.\n\nCONSTRAINT: forbidden(improvise_core, io). The TRAIT belongs in improvise-core; any IO-touching implementation belongs in improvise-io. Do not let the trait signature drag IO types into core; if it needs Result, that is a boundary decision worth arguing rather than defaulting (AGENTS.md keeps Option/Result at the edges).\n\nWHY IT IS STILL WORTH DOING ON ITS OWN WHEN IT IS UN-DEFERRED: it is the seam every later option needs -- live-backing, a test double, or the import-once path ADR 003 rejected as the ONLY answer but did not forbid as A path; it makes \"the model is fully in RAM\" an explicit property of one implementation rather than an invisible assumption of the whole crate; and done as a pure refactor it is cheap and reviewable, where doing it AS PART OF adding a SQLite source mixes a large refactor with a large feature and makes both unreviewable.\n","notes":"\n--- READ-ONLY DECIDED (user, 2026-09-19), and it shapes the trait ---\nA live-backed model is READ-ONLY, and not reluctantly: for many use cases\nediting capabilities would be a DOWNSIDE.

Sessions does not own the App -- connect(\u0026mut self, app: \u0026App, ..), apply(\u0026mut self, app: \u0026mut App, ..) and project_all(\u0026mut self, app: \u0026App, ..) all take it as a parameter.

Two residual issues:\n\n(a) SPURIOUS PROJECTIONS. Dirty comes from the EffectKind, not from whether anything happened, so a no-op still dirties everything at that level and reaches every client. Measured: ApplyAndClearDrill dirties grid+category_tree+formulas; AcceptWizardModel dirties those plus view_list+tile_bar, emitting a non-empty projection list for a no-op.\n\n(b) THE STAGED STATE IS GLOBAL AND THE COMMAND IS NOT ADDRESSED. Sessions::apply routes Command::Model with no SessionId, while drill_state and wizard live on the single authoritative App. So client B sending Model(ApplyAndClearDrill) commits client A uncommitted staged edits, and Model(AcceptWizardModel) installs the workbook A half-finished wizard built -- replacing the document under everyone.\n\nThat collides with the user ruling on improvise-tom1: staged drill edits belong to whoever staged them and must not be visible to others. Committing them on someone else behalf is the stronger version of the same violation. Gotcha 30 calls this state session-local residue; the command layer now lets an unaddressed message act on it.\n\nDECIDE: either these commands become addressed (a SessionId, and the effect acts only on that session staged state -- which means the staging map moves off the single App), or they are removed from the wire vocabulary and stay key-path only.

Goal: let a user fit a decision tree over the model's own data and land the result as a first-class computed measure.\n\nThe enabling fact: gp-tree's Tree maps 1:1 onto improvise's EXISTING formula AST. Tree::Split{feat,thresh,lo,hi} is IF(feat \u003c thresh, lo, hi) and Tree::Leaf(s) is a number. improvise-formula already parses exactly this shape, nesting included — see parser.rs:765, parse_formula(\"X = IF(A \u003e B, IF(C \u003e D, 1, 2), 3)\"). So a fitted tree can be emitted as formula TEXT and inherit everything the formula layer already does: fixed-point recomputation, persistence in the ## Formulas section, the formula panel, drill-down. No changes to the formula engine, evaluator, or file format.\n\nThree known obstacles, addressed by the child issues: (1) gp-tree's preprocessing (type inference, one-hot encoding, imputation) lives in examples/fit_csv.rs, 1261 lines that library consumers cannot call; (2) the GA search loop lives there too — the library exposes operators (Population, GaConfig, breed) but no fit entry point; (3) gp-tree's Rng is a trait the caller implements by design, and improvise has no PRNG dependency.","design":"New bridging crate improvise-gp depending on gp-tree + improvise-formula + improvise-core, keeping the enforced-boundary graph from improvise-xgl intact: the emitter cannot live in gp-tree (that would invert the dependency) and cannot live in improvise-formula (which must not know about GP). improvise-gp sits above both.

For each impl Effect for Foo, audit which slice(s) it mutates. If apply only touches ModelState (or only ViewState), narrow its signature from fn apply(\u0026self, app: \u0026mut App) to fn apply(\u0026self, model: \u0026mut ModelState) (or ViewState). Cross-cutting effects (read layout, change mode that triggers layout rebuild, etc.) stay on \u0026mut App. Improves type-level documentation and enables finer-grained effect tests. Lower priority — vb4's acceptance criterion (4) explicitly allows leaving cross-cutting on \u0026mut App.","design":"Hidden trait-design decision surfaced during vb4 step 4 review: the issue's\nphrasing — \"narrow its signature from fn apply(\u0026self, app: \u0026mut App) to\nfn apply(\u0026self, model: \u0026mut ModelState)\" — is not directly possible. You\ncannot change one Effect impl's signature without changing the Effect\ntrait. Three approaches, none picked:\n\n(A) Split into multiple traits — ModelEffect / ViewEffect / AppEffect.\n    Each impl becomes the narrower thing it actually is. Cost: ~50\n    existing impls reorganize across three traits, and Vec\u003cBox\u003cdyn Effect\u003e\u003e\n    has to become an enum wrapper (or three parallel queues) to keep\n    apply_effects working. Highest fidelity to the issue's literal wording.\n\n(B) Keep one trait, rebind inside the impl body — e.g.\n    fn apply(\u0026self, app: \u0026mut App) { let view = \u0026mut app.view_state; view.mode = ... }\n    so the slice is visible at the call site without changing the\n    signature. Lowest disruption. Doesn't strictly satisfy acceptance\n    criterion (1) (a \"narrower borrow\") — only the body is narrower.\n\n(C) Default-method dispatch on a single trait — Effect grows\n    apply_view(\u0026mut ViewState) and apply_model(\u0026mut ModelState) with\n    default impls that fall through to apply(\u0026mut App). Each impl\n    overrides only the method that matches its slice. Middle ground:\n    type-level narrowing for impls that opt in, \u0026mut App stays available\n    for cross-cutting effects. Wraps cleanly around the existing\n    apply_effects loop.\n\nPicking (A) commits to the architecture for downstream effect tagging\n(improvise-mae) and the protocol extraction (improvise-cqi).

CAUTION, new since this ticket was filed: App::apply_effects now reads dirtiness, layout_version and the record fingerprints off the EffectKind (improvise-gv9r, gotcha 40) — narrowing a signature must not put an effect somewhere that loop cannot see.","notes":"DECLINED 2026-09-20 (wave 2), with counts. Reasoning in context/code/command.md,\n'Effect::apply stays on \u0026mut App'. NOTE: this bead carries the `human` label, so\nthe decline is a recommendation the user may overturn; it is recorded rather than\nsmuggled.\n\nCOUNTED over the 49 `impl Effect` blocks in ui/effect.rs:\n  now (this branch)    8 view_state-only,  9 model_state-only, 32 cross-cutting\n  base 52507a6         9 view_state-only, 16 model_state-only, 24 cross-cutting\nThe narrow set fell from 25 to 17 in one wave. The mover was improvise-9mo9,\nwhich made nine reshaping effects call app.reset_cursor(): a reshape lives in\nmodel_state.workbook and the cursor it invalidates lives in ViewState, so the\neffects that matter most are precisely the ones that reconcile the two slices.\nNarrowing bets against the direction the code moves in.\n\nFOUR GROUNDS\n1. The narrow set is small and shrinking, for that architectural reason.\n2. The type-level documentation already exists and is CHECKED: Effect::kind()\n   has no default (gotcha 3) and apply_effects reads that one answer three times\n   (gotchas 40, 45). A narrowed signature is a second statement of the same fact,\n   free to disagree -- the defect, not the cure.\n3. Every offered mechanism weakens a guard. (A) three traits needs three queues\n   (destroys batch order, which gotchas 21/23/43 lean on) or an enum wrapper (a\n   fourth classification beside EffectKind). (C) default methods give `apply` a\n   DEFAULT, exactly what kind() does without and for the same reason: overriding\n   apply_view on an effect that needs the model compiles and writes the wrong\n   slice silently; overriding neither compiles as a no-op. (B) does not meet the\n   ticket's own acceptance criterion.\n4. \"Finer-grained effect tests\" is not blocked: effect.rs's 64 tests already call\n   Effect.apply(\u0026mut app) against a one-line App::new(wb, None) fixture.\n\nWHAT IS NOT DECLINED: approach (B), rebinding the slice at the top of an apply\nbody, remains available as a per-function style choice. It is not mandated.\nUSER CONFIRMATION 2026-09-20: the decline is CONFIRMED and the bead stays closed. This bead carries the 'human' label, so the WU-N agent correctly recorded its decline as a recommendation rather than acting on it unilaterally; the user was shown the counts (8 view-only / 9 model-only / 32 cross-cutting of 49, down from 9/16/24 at the wave base) and all three approaches (A: three traits; B: rebind in the body; C: default-method dispatch), and chose to confirm the decline.\n\nThe reasoning the user accepted: the classification ALREADY EXISTS and is checked — Effect::kind has no default and apply_effects reads that one answer three times — so a narrowed signature is a second statement free to disagree with it. Three traits need three queues (destroying batch order) or an enum wrapper (a fourth classification). Default methods would give apply a DEFAULT whose wrong answer is silent, which is precisely what kind()'s no-default rule exists to prevent.\n\nThe fact worth carrying past this bead: improvise-9mo9 moved nine effects from 'touches one slice' to 'cross-cuts' INSIDE THE SAME BRANCH that declined this, and that is not a coincidence to route around. The App exists because the grid's shape lives in model_state.workbook and the cursor into it lives in ViewState, so the effects that matter most are exactly the ones that RECONCILE the two slices. A design that rewards single-slice effects would have been pulling against the repo's actual centre of gravity.\nCOUNTS CORRECTED 2026-09-20, after adversarial review of PR #49. The decline\nstands; the numbers it was argued on were wrong twice and the user confirmed it\npartly on them, so the correction is recorded loudly rather than restated.\n\nPUBLISHED (wrong): 49 effects; 8 view-only, 9 model-only, 32 cross; narrow set\nfell 25 -\u003e 17.\nCORRECT:           57 effects; 16 view-only, 9 model-only, 32 cross; narrow set\nfell 32 -\u003e 25. Base 52507a6 was 16/16/25.\n\nTwo errors. (a) It counted only the 49 `impl Effect` blocks and omitted the 8\n`simple_effect!` invocations, which also expand to an impl and are ALL view-only.\n(b) It misclassified AddItem at the base commit, because the extraction regex\ncould not see `app` followed by a newline and `.model_state` -- which is\ndoctrine(derive_then_verify) catching the person quoting it, with the exact\nfailure that doctrine was written about.\n\nWHAT THIS COSTS THE ARGUMENT: 25 of 57 is 44% of effects that could narrow, not\nthe 35% claimed; and the fall is 22%, not 32%. The direction is unchanged and is\nstill the point -- the seven movers are SetAxis, HideItem, ShowItem, ToggleGroup,\nTogglePruneEmpty, RemoveItem and RemoveCategory, every one an effect\nimprovise-9mo9 gave a reset_cursor, so the shrinkage is architectural rather than\nincidental. But the headline was overstated by about half again, and anyone\nre-opening this should argue from 32 -\u003e 25 of 57.\n\nThe other three grounds for the decline are untouched by this: the classification\nalready exists and is checked; three traits break batch order and default methods\nreintroduce a silent default; and finer-grained tests are not blocked.","status":"closed","priority":3,"issue_type":"task","assignee":"wave2-n-cleanups","owner":"el-github@elangley.org","created_at":"2026-04-26T18:16:52Z","created_by":"jeeves","updated_at":"2026-09-20T18:57:42Z","started_at":"2026-09-20T18:08:16Z","closed_at":"2026-09-20T18:11:26Z","close_reason":"Closed","labels":["area:command","human"],"dependencies":[{"issue_id":"improvise-drg","depends_on_id":"improvise-99k","type":"blocks","created_at":"2026-04-26T11:17:16Z","created_by":"jeeves","metadata":"{}"}],"dependency_count":1,"dependent_count":0,"comment_count":0}

Effects can self-heal mid-batch, but commands cannot.\n\nTrue command-level transactionality would require, between Sequence steps: apply effects-so-far, rebuild layout, build a fresh ctx, then dispatch the next command.

IT WOULD SILENTLY REOPEN improvise-8tk, A P1 DATA LOSS. apply_effects resets abort_effects at entry and when it breaks, because the flag is per batch. Applying between steps dispatches step 2 into a FRESH batch with the flag cleared -- so the Quit after a failed Save lands and the model is discarded.

Of 21 shipped Sequence bindings, 20 are TextEntry's [\u003ccommit\u003e, clear-buffer] or [clear-buffer, enter-mode], whose second step reads nothing from ctx. The one real composition, records `o`, already works because EnterEditAtCursor's effect self-heals with rebuild_layout.

Any design that applies between steps must first answer what abort_effects means across batch boundaries -- and note PR #26 has since made that harder rather than easier, because clause 4 (improvise-yqpd) wants a ROLLBACK at apply_effects, and an abort is not a rollback.

No code written; the tree was left untouched.\n\nALL THREE OF THE TICKET CLAIMS WERE TESTED:\n\n(1) \"Works over any VFS backend because the storage layer is abstracted\" -- FALSE. improvise-6mq did not deliver a VFS. Storage is four whole-document operations (read/write bytes, list, delete) with no offsets, seeking, handles or locking; invariant(storage_is_two_ops) states it as doctrine. An sqlite3_vfs needs xRead(offset,len)/xWrite/xTruncate/xLock and only the first two could even be faked -- by rewriting the whole database on every page access.\nBUT the agent PROVED SQLite can still fit before declining: rusqlite with features=[bundled,serialize] round-trips a database through bytes with zero filesystem contact (probe test passed; a one-row DB serializes to 8192 bytes). So the decline rests on VALUE, not on imagined plumbing trouble -- \"declining on a capability that actually exists would have been the wrong decline\".\n\n(2) \"A more scalable container than plaintext for very large models\" -- FALSE, MEASURED on an 18,000-cell model using the ticket own schema, VACUUMed:\n    big.improv     1,280,846 bytes\n    big.sqlite     1,568,768        +22%\n    big.improv.gz    136,264\n    big.sqlite.gz    642,897        4.7x LARGER\nFloor case: a 5-table schema holding 3 rows is 24,576 bytes against roughly 150 bytes of .improv -- about 160x. And because writes go through Storage::write(whole bytes), every save still rewrites the entire document, so the one dimension where SQLite normally wins -- incremental page writes -- is unavailable.\n\n(3) \"Enables structured queries over model state\" -- NOT DELIVERED by this design. The artifact is a closed blob; querying means deserializing the whole database into RAM beside the Model that is already fully in RAM. Anything you could ask it you can already ask DataStore::matching_values/matching_cells over interned, indexed data.\n\nALSO: cargo check --target wasm32-unknown-unknown fails in libsqlite3-sys C build. The agent was precise that this is the NIX CC-WRAPPER injecting -fzero-call-used-regs, not proof bundled SQLite can never target wasm -- but it is real evidence the repo wasm CI gate would break the day this landed.\n\nTHE COST THE TICKET DOES NOT PRICE: .improv is grammar-defined and the pest grammar is the single source of truth. A SQLite writer/reader is a SECOND IMPLEMENTATION OF THE WHOLE FORMAT -- groups, formula target categories, hidden items, collapsed groups, number formats, page/filter selections, IndexMap insertion order, the _Measure explicit-vs-formula-target split, virtual-view suppression -- which must track every future grammar change forever. And the ticket own acceptance test (model-\u003esqlite-\u003emodel identity) CANNOT DETECT DRIFT from .improv, because it never compares the two. That missing cross-format test is what made the ticket look cheap.\n\nFormat dispatch and naming were both checked and are NOT the problem: save_to/load_from are the only chokepoints, SQLite 16-byte header is a cleaner discriminator than the existing leading-brace JSON sniff, and .improv.sqlite would follow invariant(gzip_is_a_name_property).\n\nSALVAGE FILED SEPARATELY: the one claim with standing is INTEROP -- opening a model in sqlite3 or DB Browser. That is EXPORT, not persistence.","dependencies":[{"issue_id":"improvise-9ix","depends_on_id":"improvise-6mq","type":"blocks","created_at":"2026-04-14T00:40:34Z","created_by":"spot","metadata":"{}"}],"dependency_count":1,"dependent_count":0,"comment_count":0}

That is deliberate, since `every_shipped_document_loads` reads the real checkout. Trace2 can also be enabled from config: `trace2.eventTarget`, `trace2.normalTarget` and `trace2.perfTarget`, which git reads from system and global config. Pointed at `/dev/stdout`, these write into `ls-files -z`'s output exactly as the `GIT_TRACE*` variables did (improvise-2iws). Removing the environment variables, which is what PR #276 does, does not reach config.\n\n## Steps to Reproduce\nAt PR #276 head ddcdf93a (git 2.55.0), write a config file containing `[trace2] eventTarget = /dev/stdout`. Run the test binary with `GIT_CONFIG_GLOBAL=\u003cfile\u003e` (or `GIT_CONFIG_SYSTEM`) and `every_shipped_document_loads --exact`.

The env var outranks the config target. Verified: with the config above plus `GIT_TRACE2_EVENT=0`, or with `normalTarget` plus `GIT_TRACE2=0`, `ls-files -z` prints only the path.\n\n## Acceptance Criteria\n- A child-process test sets `trace2.eventTarget` (and `normalTarget`) to `/dev/stdout` in a `GIT_CONFIG_GLOBAL` file and re-runs the walk tests, which pass.\n- The same test goes red when the `=0` overrides are dropped.\n\nSame severity as improvise-2iws: the failure is loud and the setting is self-inflicted.

The author noted this in the PR body and in `context/code/tui.md` and did not file it.\n\nIn the browser, `status_msg` is shown only as a toast. `web/shell.js::createToasts` hides it after `TOAST_MS` (6000 ms) whatever the mode. The minibuffer element (`web/app.js`, `mb.prompt + mb.value`) never shows the message. So a message that belongs beside an open minibuffer, such as a refusal the user is still fixing, disappears on a timer while the prompt is still open. This is su4u's bug with a different expiry mechanism.\n\nIt is LATENT for su4u's headline case, and that is the reason to file it rather than fix it now. A formula refusal never reaches a browser at all. The client folds `CommitBuffer`'s optimistic \"Formula added\" and `ChangeMode(FormulaPanel)`. The host's \"Formula error\" is a ViewOnly write to the host's own slice. `crates/improvise-wasm-client/tests/lockstep.rs::a_formula_the_client_cannot_parse_diverges_on_the_status_line` still asserts that divergence at 2b1c5bf7, although improvise-cl7y is closed.

The rule should be the one #257 gives the TUI (see improvise-sx7h for where that rule's mode-equality proxy is wrong).

Two small things, both\nabout what happens at the edges of the fallback improvise-jytm introduced.\n\n**The panic message got worse.** `App::resolve_view` falls back to\n`workbook.active_view` for a name the document has not got, then indexes\n`workbook.views[default]`. `Workbook::active_view()` — which several of these call\nsites used before — carries `.expect(\"active_view always names an existing view\")`.\n`IndexMap`'s `Index` impl panics with no such message. So a `Workbook` whose\n`active_view` names nothing (which only a hand-built or deserialized-from-elsewhere\nworkbook can be, since `create_view` and `delete_view` both maintain it) now fails\nwith a bare index panic where it used to name the invariant that was broken. Cheap\nfix: keep the `.expect` string.\n\n**A host-initiated `DeleteView` bypasses `adopt_deleted_views`.** That function runs\nin `Sessions::apply_model`, which is the door a *client's* command comes through. A\nhost driving `App::apply_effects` directly — through `Host::app_mut()` — deletes a\nview without any session mirror being moved off it.\n\n**Read the unreachability argument carefully, because it is weaker than it looks.**\nA first version of this ticket said `app_mut()` had one caller, in\n`improvise-ws-server/src/main.rs`, at startup, before any client had connected. That\nwas wrong, and review caught it. The one caller is\n`crates/improvise-worker-server/src/worker.rs:64`, inside `persist()` — which runs\n**after every accepted model command, with a client connected**. The bypass is still\nunreachable, but only because `persist()` happens to pass `effect::Save`, which\ndeletes no view. \"The one existing caller passes a harmless effect\" is a much thinner\nguarantee than \"nobody is connected yet\", and it is the exact shape of premise this\nrepo has been burned by: gotcha 47 records that the lost update `CheckedBatch` later\nfixed had shipped under an unreachability argument too.\n\nThe second is the interesting one to decide rather than to patch: it is the general\nshape of \"session bookkeeping that only the session door performs\". `Host::project`\nis already where every outbound path funnels, so whether the adoption belongs there\ninstead is the design question.\n\n## Steps to Reproduce\n\nThe panic message:\n\n1. Build a `Workbook` whose `active_view` names a view not in `views` (only reachable\n   by constructing the struct directly — the constructors maintain the invariant).\n2. Call `App::view()`. It panics from `IndexMap`'s `Index` impl with no message,\n   where `Workbook::active_view()` would have said which invariant broke.\n\nThe bypass:\n\n1. A client connects and switches to \"Second\".\n2. The host calls `host.app_mut().apply_effects(vec![Box::new(DeleteView(\"Second\"))])`\n   — the same door `improvise-worker-server`'s `persist()` uses for `effect::Save`\n   after every accepted model command.\n3.

Not filed as a bug because nothing misbehaves today; filed because the signature promises something the body does not do.\n\n`Model::evaluate_aggregated` takes `none_cats: \u0026[String]` and only ever tests `none_cats.is_empty()`. The aggregation itself is over `key.0` via `matching_values`. So the parameter is a BOOLEAN WEARING A LIST'S TYPE.\n\n## Steps to Reproduce\n\n1. Read `Model::evaluate_aggregated`'s signature: it takes a slice of category names.\n2. Read the body: the slice is consulted once, for emptiness. No element is ever examined.\n3. Pass a list with different contents but the same emptiness — the result is identical.\n\n## Why it is worth an hour\n\nThe name promises the function filters by that list. It does not. A caller reasoning about which categories are on `Axis::None` will believe this function honours them, and the next person to add a case will thread a carefully-built list into a parameter that cannot use it. That is the same shape as `prune_axis_items` taking a flag vector before it took a predicate: a parameter whose type admits states the body cannot distinguish.\n\n## The fix is a decision, not a rename\n\nEither the emptiness test is the real dispatch — in which case take a `bool` (or better, an enum saying what the two states MEAN) and let the caller compute it — or the function was meant to filter and does not, which is a behaviour question and needs a test first.

The better question, worth one line of thought first: should `add_category` refuse a leading underscore outright?

The category therefore never appears in a pivot, while every other consumer believes it is a normal one.\n\nFour lines away, `is_records_layout()` (`:67-74`) asks `CategoryKind`, and `CategoryKind` is imported at `:6`.\n","acceptance_criteria":"Both sites use CategoryKind, so there is one answer.

This is EXPORT for interop -- a user opening their model in sqlite3 or DB Browser to run their own queries. One-way, no round-trip obligation, and therefore none of the grammar-duplication risk that killed improvise-9ix: a second FORMAT must track every future change to improv.pest forever, a second VIEW need not, because nothing loads it back. It sits naturally beside export_csv/export_csv_to in crates/improvise-io/src/persistence/export.rs.\n\nWHY IT IS DEFERRED ANYWAY: it is the one bead in the SQLite cluster with no dependency on ADR 003, but it carries the same cost as the cluster's real work -- a rusqlite dependency and a wasm-gate verification -- for a capability nobody has asked for concretely. The user's ruling was to defer the cluster as a unit. Un-defer on a concrete interop request, or alongside improvise-rucf.2 (the SQLite source), where the dependency is being added anyway and the incremental cost of an exporter is small.\n\nNOTE THE DIRECTION IS OPPOSITE TO ADR 003'S. ADR 003 is about READING someone else's database as a live source. This is about WRITING ours out as a convenience. They share only the rusqlite dependency and the gating constraint; do not let one justify the other.\n\nTHE ONE REAL COST: cargo check --target wasm32-unknown-unknown fails in the libsqlite3-sys C build under this repo's nix cc-wrapper, so this must be NATIVE-ONLY AND FEATURE-GATED with the wasm CI job passing untouched. VERIFY that rather than assume it -- the improvise-9ix agent was careful to note the failure is the nix wrapper injecting -fzero-call-used-regs rather than proof that bundled SQLite cannot target wasm, so the gating is about protecting the browser bundle, not about an impossibility.\n\nSCOPE WHEN IT LANDS: choose a schema that is USEFUL TO QUERY rather than one that mirrors internal storage -- a reader wants cells joined to their coordinates, not an interned key blob.

Projecting the full keyset for every aggregate is untenable and the cost runs OPPOSITE to the value. A stored cell has fixed coordinates so it lands in exactly one displayed cell -- the keysets PARTITION rather than multiply -- but that still makes the payload scale with N (the data) while everything else in a projection scales with the VIEWPORT. Aggregation is precisely what makes a large document fit a screen, so shipping the keysets undoes that compression. Worked numbers for a 1000-cell viewport at u128: ~16KB at one record per cell (where the cell would be settable anyway and no keyset is needed), ~160KB at ten, and ~16MB over a million-record document -- to render a thousand cells. Per client, re-diffed as data changes. And the cheap cases are the ones where drilling barely matters.\n\nTHE SHAPE THAT WORKS: ship at most k record hashes per aggregate PLUS A COUNT, so the payload is viewport-proportional again, and fetch the full set on demand when the user actually drills. k is a product decision -- enough rows to make a hover useful, e.g. 3 to 5.\n\nPREREQUISITE: ADR 002 (context/adr/002-naming-a-cell.md). An aggregate already carries CellId::Aggregate(AggregateHash), so drill-on-demand works without this ticket; this is purely the latency optimisation for hover. Do not conflate the two -- drilling must stay correct without any preview.\n\nNote the preview hashes are RECORD hashes, so they resolve through the same DataStore index and obey the same staleness rules: a preview row whose record has since gone simply fails to resolve.","notes":"\n--- BLOOM FILTER IDEA (user, 2026-09-19): right tolerance, different question ---\nProposal was a Bloom filter instead of an explicit keyset, on the grounds that\nfalse positives are fine given a deterministic aggregate id to ask\nauthoritatively. The tolerance argument is right; the direction needs\ncorrecting.\n\nA BLOOM FILTER CANNOT ENUMERATE. A hover preview needs ROWS -- identities and\nvalues -- while a filter answers \"is X probably in this set?\" for an X you\nalready hold. The client holds aggregates, not the underlying records, so it has\nno candidates to test. So this does not serve previews directly.\n\nWHERE IT FITS INSTEAD, and it fits well: the REVERSE question, \"which visible\naggregates does record R feed?\" A client staging an edit to R tests R against\neach visible cell filter and marks the hits pending -- greyed, spinner -- with\nno round trip. A false positive marks one extra cell pending; it never misses\none. That asymmetry is exactly gotcha 35 rule: over-reporting costs work,\nunder-reporting is the bug, which is why Dirty::of is a deliberate\nover-approximation. Same shape.\n\nSIZE CORRECTION THAT MAKES IT CHEAP: a conventionally-sized filter still scales\nwith N -- roughly 9.6 bits per element at 1% FP, so ~1.2KB for a cell\naggregating 1000 records, and the payload again scales with the DATA. FIX THE\nWIDTH instead: a fixed 64- or 128-bit filter per cell is viewport-proportional\nby construction. Small aggregates are precise; large ones SATURATE and answer\n\"maybe\" to everything, degrading to mark-everything -- the safe direction, and\nthe same failure the design already tolerates.\n\nThe deterministic aggregate id is what makes the sloppiness safe: the\nauthoritative answer is one Drill(AggregateHash) away, so the filter is never\nload-bearing for correctness. Same structure as ADR 001 advisory reservations,\nwhere correctness never rests on the advisory layer.\n\nSO THIS TICKET NOW HOLDS TWO SEPARABLE IDEAS -- split them when picked up:\n (a) hover previews: needs a BOUNDED EXPLICIT keyset (k hashes + a count),\n     because a preview needs rows;\n (b) optimistic edit feedback: a FIXED-WIDTH Bloom filter per aggregate,\n     answering which visible cells a pending record edit affects.\n(b) belongs with ADR 001 layer 2 rather than here.\nDEFERRAL RE-AFFIRMED 2026-09-19 during the whole-backlog campaign, status set to deferred so it stops appearing as ready work.\n\nThe reason it is recorded rather than closed is unchanged and is the important part: drilling is already correct without it (CellId::Aggregate resolves on demand), and the trap this bead exists to prevent is someone building the UNBOUNDED version -- projecting every aggregate's full keyset, whose payload scales with the data while every other projection scales with the viewport.

A prefix was rejected because it puts a sigil into the name space where a category and a measure may legitimately share a name, the exact ambiguity _Dim carries an index to avoid (gotcha 1). Committing a name does NOT set the coordinate: that would move every measure cell in the row (gotcha 1) on the same Enter as a schema change, in an app with no undo.\n\nMAX_CATEGORIES refuses VISIBLY, which took a second fix: the refusal was written and never drawn, because CommitAndAdvance re-enters editing and draw_bottom_bar renders the minibuffer instead of the status line. AddCategory now aborts the batch and CommitAndAdvance emits its mode change FIRST. The limit stays checked in exactly one place, Model::add_category.\n\nFOUR characterization tests updated knowingly, each recording why.\n\nFOLLOW-UP FOUND BY THE POST-WAVE REVIEW: a refused or DUPLICATE AddCategory still bumps layout_version and dirty -- improvise-75ld.","dependencies":[{"issue_id":"improvise-2zq","depends_on_id":"improvise-c5v","type":"blocks","created_at":"2026-08-29T12:32:45Z","created_by":"Edward Langley","metadata":"{}"}],"dependency_count":1,"dependent_count":0,"comment_count":0}

A media query under 900px now scrolls each\nplayer sideways at a legible size instead: 11.95px, measured the same way, with\nthe PAGE's own scrollWidth still equal to its clientWidth, so the overflow is\ncontained inside the player and there is no horizontal page scroll.\nTWO CORRECTIONS TO THE NOTE ABOVE, and one thing it should not be read as saying.\n\nFIRST, THE NUMBERS IN THAT NOTE ARE NOW WRONG.

They were, and `drill.cast` fails: it shows the narrow records\nformat with a single `Value` column, which improvise-c5v and improvise-2zq\nreplaced with a column per measure plus the `+cat` and `+` columns.

Leaving `pkg/` and\n  `worker-pkg/` at the root would have meant editing the wasm-pack generated\n  glue; every path in app.js and worker.js is relative, so moving the bundle\n  together keeps all of them correct and the glue untouched. `worker.js`'s\n  `fetch(\"demo.improv\")` resolves against the WORKER's url, so the seed follows\n  the move for the same reason.\n* `web/assemble.sh`'s four `stamped` guards had to follow the files. They are\n  the only check that the cache-bust substitution worked, and a guard pointed at\n  a path nothing writes fails in the direction that looks like success.\n* `harness/tests/shell.spec.js` navigates to `/index.html` six times, including\n  the `?ws=` and `?doc=` variants. Every one of those now lands on the landing\n  page, so all six were repointed at `/app/index.html`. The browser harness is a\n  CI job that can fail the build, so this was not optional and not someone\n  else's to discover.\n\nVERIFIED against the ASSEMBLED tree, not against docs/ directly, because a path\nmove is exactly what re-arms the trap this page already caught once: the four\ncasts play 37 lines each at the root, the primary call-to-action resolves to\n/app/ and returns 200, and there are no failed requests and no page errors. The\ncall-to-action check was proved able to fail by pointing the link at ./aap/,\nwhich returns 404 while the page still looks entirely correct.","status":"closed","priority":4,"issue_type":"feature","assignee":"wave2-p-milestones","owner":"el-github@elangley.org","created_at":"2026-04-09T04:05:53Z","created_by":"Edward Langley","updated_at":"2026-09-20T18:10:48Z","started_at":"2026-09-20T18:02:40Z","closed_at":"2026-09-20T18:04:51Z","close_reason":"Both children terminal: improvise-3gy was already closed, improvise-e61 closes\nwith this wave.\n\nTHE COLLISION THIS TICKET ASKED TO RESOLVE FIRST, resolved: Pages serves the\nstandalone web app at the root (improvise-d31/bck), and the landing page now\nsits BESIDE it at /landing/ rather than replacing it.
