+summary: Glasses completion notifications now recognise a board whose finished lane is not called Done.
+category: fix
+dev: `diffSnapshots` declared a per-task `completeColumnsByTaskId` that no caller ever built, so its completion test fell through to the literal `"done"`. `notifier.ts` now builds it (per task, with a shared IR cache, and only when `alsoNotifyOnDone` is on). The `unwired-lane-parameter` guard now scans `plugins/`, walks inline options-object types, and scopes its "is it wired" search to files that name the declaring symbol — which surfaced 17 further unwired declarations, now recorded as a ratcheted baseline.

+The KNOWN-UNWIRED baseline, and why a guard that reported `[]` is being changed to report 18.
+
+This assertion used to be `toEqual([])` and it passed — because the mention rule it ran on ("the
+parameter name appears in ANY other file") is satisfied by coincidence for every ordinarily-named
+parameter. `completeColumns` alone is a local variable in 15 unrelated production files. The guard
+was not clean; it was answering a question too weak to fail.
+
+Tightening the rule to "the mention must come from a file that also names the declaring symbol"
+surfaced these 18 at once. Spot-checked before recording rather than assumed: `buildUnblockWeightMap`
+in `task-priority.ts` declares `terminalColumns` and `reviewColumns`, and the only files that pass
+either are its own tests — the production caller uses the built-in `{done, archived}` default, which
+is the inert-conversion shape this module exists to name.
+
+Recorded as a RATCHET, in the shape `scripts/lifecycle-column-census.mjs` already uses here: a new
+unwired declaration fails immediately, and each of these can only leave the list. Keyed on
+file + parameter rather than line so an unrelated edit above them does not manufacture a failure.
+
+Wiring them is not this change's job — they span core, engine and dashboard, i.e. three other
+batches — and pretending they did not exist for another week is worse than listing them.

+
+      `diffSnapshots` declared a per-task `completeColumnsByTaskId` that this — its only caller —
+      never built, so its completion test fell through to the literal `"done"` on every real poll.
+      That is the unwired-lane-parameter class, and it is what this change set exists to fix.
+
+      MY FIRST FIX USED THE WRONG SHAPE, which is worth recording because I wrote the warning against
+      it myself. I replaced the per-task map with a flat set from `resolveProjectColumnsForRoles`
+      because it was one read instead of N. But that helper is the READ-shaped answer: it ALWAYS
+      unions the legacy `done` in, which is inert for a query and a false positive for a per-card
+      decision. A workflow that declares `shipped` as its complete lane and reuses `done` as an
+      ordinary lane would have fired a "completed" notification for live work. The header of
+      `project-lane-vocabulary.ts` names this exact mistake — "answering a per-card question from
+      this union" — and I made it anyway, one module over.
+
+      The original author's shape was correct and their comment said why: the poll spans the whole
+      board, so one workflow's complete column can be another workflow's WIP column. Restored.
+
+      THE COST OBJECTION IS ANSWERED BY THE GATE, not by the shape. `alsoNotifyOnDone` decides
+      whether the map is consumed at all, and it is `false` here today — so the per-task reads cost
+      exactly nothing now, and the day someone enables the flag they get the correct answer rather
+      than a cheap wrong one. An IR cache is shared across the tasks so distinct workflows, not
+      distinct cards, drive the resolution count.
+
+      Best-effort per card: a card whose workflow cannot be resolved is simply absent from the map
+      and falls back to the documented legacy default, rather than dropping the whole poll.

+
+      `alsoNotifyOnDone` is a hardcoded `false` with no setting behind it — grep it: the only writer is

+      The mention must come from a file that also names the DECLARING symbol.
+
+      The original rule — "the parameter name appears in any other file" — is unusable for any name
+      that is also a common local variable, and I proved it on myself within one edit: renaming an
+      unwired parameter from `completeColumnsByTaskId` to `completeColumns` made the guard go quiet
+      immediately, because 15 unrelated production files happen to declare a local called
+      `completeColumns`. The check had not been satisfied; it had been switched off by a rename.
+
+      That is precisely the "evadable by a style choice" failure this module condemns, so the fix is
+      the cause rather than a name blocklist: a file that never references `diffSnapshots` cannot be
+      the thing that wires `diffSnapshots`'s options.
+
+      Still deliberately loose — this is a co-occurrence test, not a call-graph analysis. It keeps
+      the false-positive rate that makes the guard bearable while removing a false NEGATIVE that
+      scaled with how ordinary the parameter's name was.
