- gen is a reserved keyword (→ renamed module to generator)
- ref in patterns with implicit borrowing (→ removed ref)
- & pattern with implicit borrowing (→ added & to outer pattern)
Update application initialization and example data.
- `App::new` now recomputes formulas on startup to ensure formula-derived
values are available immediately.
- Updated `examples/demo.improv` to reflect changes in formula and category
structure.

Update persistence logic for formulas and categories.
- Formulas targeting `_Measure` no longer include the category suffix in
Markdown.
- `_Measure` items are now excluded from the category section in Markdown
to avoid duplication with the formulas section.
- Improved Markdown parsing to correctly handle formulas without an
explicit category suffix, defaulting them to `_Measure` .
- Added logic to skip virtual index and dimension categories during
persistence.

Refactor command execution and buffer management.
- `CommitFormula` now defaults to targeting `_Measure` .
- `CommitFormula` no longer automatically clears the buffer; buffer
clearing is now handled by keymap sequences.
- Added `ClearBufferCmd` to the command registry.
- Updated `AddFormulaCmd` to support optional target category.
- Added `SetBuffer` effect to allow clearing buffers.

Implement keymap inheritance and sequence bindings.
- Added `parent` field to `Keymap` to support Emacs-style inheritance.
- Implemented `lookup` in `Keymap` to fall through to parent keymaps.
- Added `bind_seq` to allow multiple commands to be bound to a single key
pattern.
- Refactored existing keymaps to use sequences for common patterns like
Esc/Enter/Tab to clear buffers and change modes.

Refactor formula handling to use a virtual '_Measure' category.
- Formulas now default to targeting '_Measure' if no category is specified.
- '_Measure' items are dynamically computed from existing data items and
formula targets, preventing redundant item storage.
- Updated persistence to handle '_Measure' formulas and items correctly in
Markdown.
- Updated UI and model to use 'effective_item_names' for layout and item
resolution.
- Updated tests to reflect the new '_Measure' behavior.

Replace "Measure" with "Foo" as target_category in formula parser
tests so they don't depend on a specific category name convention.

Add VirtualMeasure to CategoryKind description, document _Measure as
third always-present virtual category, add section on fixed-point
formula evaluation strategy.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
_Measure is now a virtual category (CategoryKind::VirtualMeasure),
created automatically in Model::new() alongside _Index and _Dim.
Formula targets are added as items automatically by add_formula.
Formula evaluation uses a fixed-point cache: recompute_formulas()
iterates evaluation of all formula cells until values stabilize,
resolving refs through the cache for formula values and raw data
aggregation for non-formula values. This fixes formulas that
reference other measures when hidden dimensions are present.
evaluate_aggregated now checks the formula cache instead of
recursively evaluating formulas, breaking the dependency between
formula evaluation and aggregation.

Model::add_formula now ensures the formula target exists as an item in
the target category (same fix as AddFormula effect, but at the model
level — covers file loading and headless paths).
Formula panel now shows raw formula text instead of debug-formatted
string with redundant target name and quotes.

When there are more tiles than fit in the available width, the tile
bar now auto-scrolls to ensure the selected tile is always visible.
Overflow indicators (◀ ▶) show when tiles exist beyond the visible
area. Scroll offset is computed fresh each frame from tile_cat_idx.

Circular or self-referencing formulas now return CellValue::Error
instead of stack overflowing. eval_expr uses Result<f64, String>
internally so errors (circular refs, div/0, missing refs) propagate
immediately through the expression tree via ?. The depth limit (16)
is checked per evaluate_depth call — normal 1-2 level chains are
unaffected.
Also adds CellValue::Error variant for displaying ERR:reason in the
grid, and handles it in format, persistence, and search.

When adding a formula interactively, the target (e.g. "Margin") was
registered as a formula but never added as an item to the target
category. The grid layout never created cells for it, making the
formula invisible. Now AddFormula::apply calls add_item before
registering the formula.

40-row CSV with obviously-fake sales data (fictional companies like
Acme Corp, Wonka Industries, Cyberdyne Systems). demo.improv generated
via headless import with Profit formula and a default view showing
Region+Product on rows, Date_Month+Measure on columns. Added the
import command to the README quick-start section.

Add dedicated sections for the data model (formula examples), views and
axes (tile mode, records mode, drill-down), the .improv file format
(annotated example), import wizard and headless scripting, and the
command/effect architecture. Link docs/design-notes.md from the "Why"
section. Update build instructions to use `nix build .`.

Audited SPEC.md against code — mostly accurate but redundant with
repo-map.md and design-principles.md. Minor drift in storage internals,
wizard step count, and mode representation. Salvaged product vision and
non-goals into docs/design-notes.md with staleness disclaimer.

Add CL/SQL-style symbol quoting using pipe delimiters for formula
identifiers. This allows category and item names that collide with
keywords (WHERE, SUM, IF, etc.) or contain special characters
(parens, operators, spaces) to be used unambiguously in formulas:
|WHERE| + |Revenue (USD)|
SUM(|Net Revenue| WHERE |Region Name| = |East Coast|)
Pipes produce Token::Ident (same as bare identifiers), so they work
everywhere: expressions, aggregates, WHERE clauses. Double-quoted
strings remain Token::Str for backward compatibility.
Also updates split_where and parse_where to skip/strip pipe delimiters.
