A variant nothing composes at all is immune to both, since its only pattern occurrence is its own fold arm, which `=>` identifies. +### And forwards: every effect is on the wire or has a verdict (improvise-h3y7) + +`vocabulary_is_composed.rs` checks that the vocabulary does not name more than +production composes. The other direction is *does the vocabulary name +everything it should?* That was the direction `ViewBack` and `ViewForward` +failed: they were missing, and no client had a back history. Until improvise-h3y7 +nothing checked it, and the audit that finally ran it by hand under-reported. +Brace-matching `impl Effect for` blocks misses the eight `simple_effect!` +expansions and `SetTransientPrefix` in `command/keymap.rs`. All nine are +`ViewOnly`, which is the half the `ViewBack` bug was in. + +`improvise-command/src/ui/reduce/vocabulary_is_complete.rs` is that direction. +It scans the crate's `src/` for both ways an effect is declared, and requires +each name to be a `Command` or `ModelCommand` variant (read off serde's derive) +or to appear in `NOT_ON_THE_WIRE` with a verdict. A verdict is one of four +kinds, and the check verifies each kind: + +- `Command(v)`: on the wire under another name (`HelpPageNext`/`Prev`/`Set` → + `Command::HelpPage`). `v` must be a real variant. +- `Frame(v)`: answered by a `ClientFrame` that is not a `Command` (`Save` → + `ClientFrame::Save`, gotcha 45). `v` must be a real frame. +- `Off(why)`: excluded on purpose, with the argument: session-local residue + (gotcha 30), host-local caches, or batch-relative control flow. +- `Gap(ticket)`: missing, and a ticket owns closing it (`SaveAs`, `ExportCsv` → + improvise-2mqz). + +The list is also checked in reverse. An entry that is now on the wire fails, +and so does an entry that names no effect. A test-only fake effect is scanned +on purpose. It fails loudly and never passes silently. + +What it does **not** check is whether a same-named pair *agrees*: whether +`reduce_view`'s arm does what the effect does. The name match is the +completeness half. The semantic half stays a per-pair read (improvise-h3y7's +notes put it at about 21 pairs). The resolver lists in `resolve.rs` +(`declined()` and the host-only names) are also not checked against the +vocabulary yet. The audit found them stale in three places. + +### No `ModelCommand` field is a position (improvise-hkbc) + +improvise-6nsd closed "a stale layout tier misdirects a mutation" on one +condition: no `ModelCommand` carries a row or column index. `position_free` +in `reduce.rs`'s tests enforces that at compile time. It destructures every +variant with no `..`, down into `RecordCell`, and hands each field to a +function that accepts only a name, a path, a surrogate, a value or an axis. So +a new variant, a new field, or a field retyped to `usize` fails to build, and +the build failure forces the ADR conversation. It **cannot** see a position +spelled as a `String`. It also does not make the client position-free: +improvise-2wu3 resolves a painted `(row, col)` against the current cache before +it ever builds a command. + ### Why two model effects are key-path only A command on this wire is routed by `Sessions::apply` with **no diff --git a/crates/improvise-command/src/ui/reduce.rs b/crates/improvise-command/src/ui/reduce.rs index 55d78cd7..e59e54cf 100644 --- a/crates/improvise-command/src/ui/reduce.rs +++ b/crates/improvise-command/src/ui/reduce.rs @@ -10,6 +10,9 @@ use crate::ui::app::App; use crate::ui::effect::{self, Effect, ViewTarget}; use crate::ui::project::{Dirty, document_projections}; +#[cfg(test)] +mod vocabulary_is_complete; + /// A wire [`Command`] whose basis the authoritative state has answered for /// (improvise-ondj/7v62, ADR 001).

The guard +is the signature of `position_free`. It destructures every variant with no `..`, +down into `RecordCell`, and hands each field to a function that accepts only +`&str`, a path, a `RecordHash`, a `CellValue`, an `Axis` or an optional name. +The `#[test]` only keeps that signature compiled and reached. + +Faults injected, one per half, each compiling only `improvise-protocol`: + +- A new variant `ScrollTo { row: usize }`, also added to `records_named`'s + or-pattern the way an author would. The lib built. The test build failed + with `non-exhaustive patterns: ScrollTo` **at `position_free` and nowhere + else**. +- The same variant classified as `ScrollTo { row } => name(row)`. The test + build failed with `expected &str, found &usize`. + +A field added to an existing variant is caught too, but not in isolation, +because every constructor of that variant also fails. Reverted with +`git restore`.
