F4 [critical] — the anti-join `DELETE … WHERE NOT EXISTS(child)` was still racy
under Postgres READ COMMITTED: a reply INSERT holds FOR KEY SHARE on the parent;
the DELETE's start snapshot doesn't see the uncommitted child (NOT EXISTS true),
blocks on the reply's lock, and when the reply commits the parent was only LOCKED
(not modified) so EvalPlanQual does NOT re-check → the DELETE proceeds and CASCADE
destroys the just-committed reply. Replaced with a transaction: SELECT the parent
FOR UPDATE (conflicts with the reply's FOR KEY SHARE → serializes the concurrent
reply), re-check for a child with a FRESH statement in the same tx (a new RC
snapshot sees a just-committed reply), delete only if still childless (return 1)
else return 0 (caller resolves). The FOR UPDATE lock is held to end-of-tx so no
reply can insert between the re-check and the delete. Signature unchanged, so the
service + its mocked unit tests are untouched; docstrings updated.
F5 [warning] — the client Dismiss button was gated only on canComment, but the
server now gates dismiss on owner-or-space-admin, so a non-owner non-admin saw a
button the server 403s. `canShowDismiss` now also requires
`isOwnerOrAdmin = currentUser?.user?.id === comment.creatorId || userSpaceRole ===
"admin"` (the same gate the comment delete-menu already uses); threaded into both
call sites.
F6 [warning] — added a REAL-DB int-spec
(apps/server/test/integration/comment-delete-if-childless.int-spec.ts, + a
createComment seeder): (a) childless → returns 1, row gone; (b) committed reply →
returns 0, parent+reply survive; (c) CONCURRENCY — a second connection inserts a
reply (FOR KEY SHARE) and commits mid-operation while deleteCommentIfChildless
blocks on FOR UPDATE → asserts it returns 0 and both rows survive (a blind
anti-join would lose the reply here). Ran against live Postgres — 3/3 pass.
server tsc clean; comment jest 53 + int-spec 3 (live Postgres) pass. client tsc
clean; comment vitest 56 pass.

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.

For AI-agent-authored content (comments + page history), replace the text AI-AGENT
badge with an avatar stack: the agent in front, the human who launched it smaller and
behind. This fixes the inverted hierarchy (the action was the agent's; the human just
launched it). closes#300.
Backend: a single server-authoritative resolver resolveAgentProvenance normalizes to
{ agent, launcher } from server columns only (createdSource/lastUpdatedSource, aiChatId,
creator, chat role) — nothing from request input, so agent identity can't be spoofed.
Internal chat -> agent = chat role (name/emoji), launcher = human; external MCP
(aiChatId null) -> agent = the agent account, launcher = null; non-agent -> neither.
The role join (aiChatId -> ai_chats.role_id -> ai_agent_roles) deliberately does NOT
filter enabled/deleted_at, so a later-disabled role still labels historical content
(mirrors findById, not findLiveEnabled). Enrichment is applied on BOTH findPageComments
(list) AND findById (the create/resolve/update broadcast path), so the stack shows on
live comment events and doesn't vanish on resolve/edit.
Frontend: new AgentAvatarStack + AgentGlyph (avatarUrl -> role emoji on violet ->
IconSparkles on violet), integrated into comment-list-item and history-item where the
badge was; the deep-link-to-chat click moved onto the stack. ai-agent-badge removed.
Tests: AgentAvatarStack (role/no-role/MCP/click/non-clickable), the provenance resolver
+ recorder tests proving the role join never filters enabled/deleted, and findById
enrichment (guards the live-broadcast regression).
