* perf(issues): stop full timeline re-render on every WS event (MUL-1941) Two compounding causes made every Comment/reply WS event re-render every sibling thread on the issue detail page — visible during AI streaming as a flash across all 10 nested replies under a parent and as the green reply-input losing its draft. 1) `useCreateComment.onSettled` invalidated the timeline query, forcing a full `GET /timeline` refetch on every comment submit. The response replaced every entry's reference even when the content was unchanged, poisoning every downstream React.memo. The `comment:created` WS broadcast already keeps the cache fresh and `useWSReconnect` invalidates on disconnect, so the redundant refetch had no upside. Drop it. 2) The `timelineView` useMemo passed the full `repliesByParent: Map` to every CommentCard. Each WS event rebuilt the Map (new ref), so React.memo on CommentCard fell back to a re-render for *every* card, not just the one whose thread changed. Replace the Map prop with a per-thread `replies: TimelineEntry[]` slice, precomputed once via `collectThreadReplies` and stabilized against the prior render — when a thread's flat list is shallow-equal to last time, reuse the previous array reference so unrelated cards keep their memo. ResolvedThreadBar gets the same `replies` prop, so the collapsed count + author list still match the expanded view without re-walking the graph. Verified: pnpm typecheck + pnpm test for @multica/views and @multica/core (334 + 214 tests, all passing). Co-authored-by: multica-agent <github@multica.ai> * fix(realtime): mark timeline stale without refetching active queries (MUL-1941) Per GPT-Boy's review on PR #2329: dropping `useCreateComment.onSettled`'s invalidate wasn't enough. The global `useRealtimeSync` runs in WSProvider for the lifetime of the app and re-invalidates the timeline on every `comment:created` / `comment:updated` / `comment:deleted` / `comment:resolved` / `comment:unresolved` / `activity:created` / `reaction:added` / `reaction:removed` event. With `staleTime: Infinity` on the QueryClient default, the active timeline query refetches on every invalidate — replacing every entry's reference and busting the per-thread memoization the prior commit just put in place. Switch the global handler's `invalidateQueries` to `refetchType: "none"`. Active observers now stay fresh via the granular `setQueryData` handlers in `useIssueTimeline`; inactive issues' caches are still marked stale, so when IssueDetail mounts later, `refetchOnMount` triggers a fresh fetch the same way it did before. `comment:resolved` / `comment:unresolved` previously had no granular handler — only the global invalidate kept the cache in sync. Add useWSEvent handlers in `useIssueTimeline` that replace the matching entry via `commentToTimelineEntry`, and extend that helper to carry the resolved_at / resolved_by_type / resolved_by_id fields so resolved state survives the round-trip (it was silently dropped on every `comment:updated` too — fixed as a side effect). Tests: 3 new cases covering resolved / unresolved / cross-issue isolation in the timeline hook. All 337 + 214 unit tests + full monorepo typecheck pass.
