claude code agent 227 e6d8eda8e5 fix(comment): dismiss owner/admin authz + atomic conditional delete + 404-only onError (#329 review)
Maintainer escalation decision (B) + reviewer findings on the ephemeral-
suggestion PR.

Authz (decision B): POST /comments/dismiss-suggestion now gates the destructive
branch on owner-OR-space-admin, mirroring POST /comments/delete exactly (same
SpaceCaslAction.Manage / SpaceCaslSubject.Settings, same owner short-circuit,
same ForbiddenException). A non-owner non-admin who tries to dismiss another's
childless suggestion gets Forbidden before the service runs. Apply stays on
canEdit (accepting an edit is the editor's semantics), unchanged.

F1 [blocking] — atomic conditional delete closes the hasChildren→delete race.
New repo `deleteCommentIfChildless(id)` runs a single
`DELETE FROM comments WHERE id=:id AND NOT EXISTS (SELECT 1 FROM comments child
WHERE child.parent_comment_id = comments.id)` (verified by compiling the Kysely
expression to SQL — the correlated subquery references the OUTER comments.id).
deleteEphemeralSuggestion strips the mark first, then the conditional delete: if
it removed the row → commentDeleted + outcome 'deleted'; if a reply raced in
(0 rows) → fall back to resolveComment (outcome 'resolved') so the discussion and
the new reply survive. No reply can be cascade-deleted anymore.

F2 [warning] — the apply/dismiss onError success-noop is narrowed from 404||400
to 404 ONLY. A 400 means the comment is ALIVE (apply's 400 = the thread was
resolved-not-applied), so it now shows a real error (surfacing the server
message) and KEEPS the comment in cache instead of a false "applied" + dropping a
live thread.

F3 [suggestion] — the 404-race client tests assert the success toast fired.

Tests: server — dismiss authz (owner ok / non-owner-non-admin Forbidden /
space-admin ok), the delete→resolve race (hasChildren=false but conditional
delete returns 0 → resolve, no commentDeleted), delete-path asserts switched to
deleteCommentIfChildless; client — apply-400 and dismiss-400 (kept in cache, red,
not success) + the toast assertions.

server tsc clean, comment+collaboration jest green; client tsc clean, comment
vitest 54 passed.

claude code agent 227 8d8ecaed82 feat(comment): ephemeral suggestion-edits — Apply/Dismiss remove the comment (#329)
Agent suggestion-edits (comments with suggestedText, #315) piled up: Apply
auto-resolved the thread, cluttering the resolved tab, and the anchors stayed in
the document. Make them ephemeral: resolving (Apply OR the new Dismiss) makes the
comment DISAPPEAR — hard-delete + remove the Yjs `comment` mark — UNLESS the
thread has replies, in which case resolve it (preserve the discussion). Manual
Resolve is unchanged. Scope: only comments with `suggestedText`.

Server:
- New collab event `deleteCommentMark` (collaboration.handler) mirroring
  resolveCommentMark, wiring the existing removeYjsMarkByAttribute to strip the
  anchor from the doc.
- `finalizeAppliedSuggestion` forks on `hasChildren`: replies → apply + resolve
  (outcome 'resolved'); none → apply + hard-delete + mark removal (outcome
  'deleted').
- New `dismissSuggestion` (validates top-level + suggestedText + not applied/not
  resolved) with the same fork; permission `canComment` (NOT canEdit — dismiss
  doesn't change page text); audit COMMENT_SUGGESTION_DISMISSED. New
  POST /comments/dismiss-suggestion; apply stays canEdit.
- Both return `{ outcome: 'deleted' | 'resolved' }` so the client picks the
  optimistic action.

Data-integrity (review F1): the shared `deleteEphemeralSuggestion` removes the
anchor mark FIRST and FATALLY, then deletes the DB row only on success. The row
delete is irreversible, so a mark-removal failure — including the
COLLAB_DISABLE_REDIS "no live instance" hard-error — must abort the whole
operation (→ 5xx, repeatable) rather than swallow the error and leave a permanent
orphan anchor pointing at a deleted comment. `deleteCommentMark` is no longer
best-effort (unlike resolve, where the row is kept and a failed mark is
recoverable).

Client:
- `canShowDismiss` (canComment) alongside `canShowApply` (canEdit); a "Dismiss"
  button next to Apply in the suggestion block.
- `useApplySuggestionMutation`/`useDismissSuggestionMutation` reconcile the cache
  on `outcome` ('deleted' → remove; 'resolved' → relocate to the resolved tab).
- Idempotent races (review F2): BOTH apply and dismiss onError reduce 404/400 to
  success (comment already gone/resolved), dropping it from the cache instead of
  a red error — restores the #315 apply idempotency the ephemeral delete would
  otherwise break.
- i18n Dismiss / "Не применять" (ru/en).

Not done (flagged): deleteCommentMark on the normal /comments/delete path — left
out (would change every non-suggestion delete + needs gateway injection; the
interactive client already strips the mark via unsetComment). Out of scope per
the issue.

Tests: server — apply/dismiss delete-vs-resolve fork, all four dismiss state
guards, the deleteCommentMark handler, controller authz (dismiss=canComment,
apply=canEdit), AND a mark-removal-failure test proving the row is NOT deleted +
the error propagates (F1). client — Dismiss show-conditions, outcome cache
reconciliation, and 404 idempotent race for BOTH dismiss and apply (F2).

Verified: server tsc clean; comment+collaboration jest 144 passed. client tsc
clean; vitest 905 passed | 1 expected-fail.

claude code agent 227 48c1ec46f7 fix(comment): store the real anchored substring as expectedText + pin authz (#318 F1/F2)
F1 [blocking]: a suggestion whose anchor matched via normalization could never
be applied (spurious 409). The comment mark lands on the doc's ACTUAL text
(Docmost auto-converts to typographic quotes/dashes/nbsp), but the stored
selection — used as expectedText at apply — was the raw ASCII agent input
(+substring(0,250)). So replaceYjsMarkedText's strict joined!==expectedText
always failed and threw "text changed" though nobody edited. Fix: new pure
getAnchoredText(doc, selection) reconstructs the exact raw doc substring the mark
covers (slicing identical to spliceCommentMark); on the suggestion path
client.createComment stores THAT as selection, so expectedText equals the marked
text and apply returns applied:true. Live anchoring still uses the raw agent
selection (normalization still finds the anchor). Truncation raised 250->2000
(+ DTO @MaxLength(2000)) so the anchored substring is never cut below the mark
span. Ordinary comments unchanged. AI-chat shares client.createComment, so
covered. Regression tests: getAnchoredText raw-vs-ASCII; create payload selection
is the typographic substring; apply with typographic expectedText -> applied.

F2 [blocking]: added comment.controller.spec.ts pinning that validateCanEdit runs
before applySuggestion (Forbidden -> applySuggestion never called; happy path ->
called; missing comment -> 404 without authorizing).

MCP 448 pass; server comment+yjs 54 pass. MCP build/ rebuilt.
