Reliably healable repairs run silently — the user-gated Repair banner retires

General ruling (2026-07-29): app-initiated covers every reliably healable repair — unambiguous, content-lossless — because heals are auditable: Pro's separate heal commit is the durable trail, base happens quietly, and a heal that changes user content announces with a warning-tone notice, never a consent gate. The user-gated class stays defined but has no current members. Duplicate-id healing goes silent under Lanework-owns-the-board (free to re-mint UUIDs at will): no condition banner, no Repair button — a scheduled heal remints withheld occurrences (memo-guarded, disk re-verified, no-op on vanished duplicates) and posts "Repaired duplicate id — 'Fix login'". Winner rule unchanged: earlier commit on git boards, filesystem birth date then traversal order without history. 06 keeps the Repair verb as the heal commit's name; 13 moves the remint outside undo with all heals. Dissolves the Repair-has-no-Nexus-row contradiction — no command, no row owed.

Board: Contradictions card ce5e7f60 → Resolved (lane now empty); Implementation card 50ed2b5d (Active) retitled "Dedupe duplicate ids and heal them silently" and realigned mid-flight.

 - **One stack per board, owned by the board session.** Not per-window: every window over a board (board window, its card windows) shares the store and shares the stack. `window.undoManager` for board surfaces returns the session's manager; 06 ▸ Undo routing applies unchanged — text-editing surfaces get their session-scoped text undo, everywhere else ⌘Z/⇧⌘Z hit the board stack. Undo is board-local, exactly as git undo was.
 - **Registration at the Writer boundary.** Every app-mediated mutation already passes through the Writer as a `WriteOperation` (02-architecture.md) — that closed enum is the exact inventory of undoable operations. Each Writer call site registers the inverse operation, computed from the pre-write snapshot the store already holds: move → move back (original lane, original `order`); reorder → restore original `order`; rename → restore title; restyle → restore prior style; resize → restore prior width; Edit-session body save → restore prior body bytes; card or lane delete (⌫) → move back out of `.trash/` (lanes rejoined the trash 2026-07-29 — the recreate-from-capture inverse retires with the last destructive delete); restore-by-move → move back in; create → remove the created folder.
-- **What is not undoable** (settled): **Permanently delete** (Delete Immediately, Empty Trash) — `purgeIsUnrecoverable` stays true in base, and the existing confirmation rule (03-board-ui.md) already fires on all base boards, since none have git history: the confirm *is* the safety. **Repair** (01-storage-format.md's duplicate-id remint) — undoing a remint would recreate the duplicate id the operation exists to remove. Both match their existing "destructive, confirmed, final" posture.

Permanently delete matches its existing "destructive, confirmed, final" posture; the remint sits outside undo as all heals do.
 - **Coalescing follows commit granularity** (settled): one gesture, one undo step — a multi-card move is one step with a plural title; an Edit session is one step, registered at the Edit→Preview flip (the effective Save — 05-card-window.md); a styling batch is one step (03's one-gesture-one-commit rule, substrate swapped). The 06 vocabulary supplies menu titles ("Undo Move 3 Cards"), via NSUndoManager's dynamic retitling — the same naming machinery both editions use.
 - **Session-only persistence** (settled): the stack lives with the board session and dies at close/quit — standard macOS behavior. Git undo's survive-relaunch property is a Pro difference, stated honestly (12's matrix).
 - **Foreign writes never join the stack** (settled): NSUndoManager can only undo what the app mediated. An agent's or hand edit is not a step — the honest capability gap vs Pro (12's matrix). Foreign changes also do not clear the stack wholesale; collisions are handled lazily, per step, by validation:
