HeyItsChloe · 2026-05-28T22:27:32Z

Skip clearEvents on same-conversation remount (Settings → back)
Guard REST seed against stale React Query cache to prevent event mixing
Re-fire REST seed after active conv is stamped to fix empty chat state
Reject stale WebSocket messages from previous conversation's socket
Flush in-progress draft on unmount before debounce fires
Wire up clearPendingMessages on conversation switch (was never called)

❌ 7 snapshots differ from the main branch baselines. Add the update-snapshots label to acknowledge intentional changes.

How to resolve:

Unintentional diffs — the baselines on main may have moved since this branch was created. Merge the latest main into this branch and re-run CI.

Intentional changes — add the update-snapshots label. CI will pass and the new screenshots become the baseline when this PR merges.
