WalkthroughChangesActivity marker preview integration
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Comment markers may stop appearing or responding after a file-version transition when the direct viewer accessor briefly exposes a destroyed viewer. The issue is bounded to marker preview behavior but should be corrected before merge. Sequence Diagram(s)sequenceDiagram

In `@src/elements/content-sidebar/activity-feed-v2/ActivityFeedV2.tsx`:
- Around line 460-462: Move the assignments to filteredItemsRef,
markerSelectedIdRef, and onCommentSelectRef out of the render path and into a
ref-sync useEffect. Declare this effect before the marker attachment effect so
marker handling and the comment_marker_select handler read committed values
only.
In `@src/elements/content-sidebar/activity-feed-v2/useCommentMarkerSelectedId.ts`:
- Around line 41-48: Update useCommentMarkerSelectedId so ref mutations and
selection bookkeeping do not occur during render; derive the returned selection
from the last committed snapshot, then update that snapshot in a layout effect
or equivalent post-commit mechanism while preserving the existing alreadyEmitted
behavior.

485-487: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winReject destroyed viewers from
getViewer.If
getViewer()temporarily returns a destroyed viewer during a version transition, this branch attaches it and stops polling. When the accessor later returns the replacement viewer, the effect does not re-run, so comment markers and selection events remain attached to the destroyed instance.Match the destruction check used for the preview viewer.
Proposed fix
const loaded = getViewer?.() ?? null; -if (loaded) { +if (loaded && !loaded.isDestroyed?.()) { return loaded; }🤖 Prompt for AI Agents
