Palace Code is healthy. Here's the summary:

**All systems passing.** The self-healing agent tested all 10 API endpoints and found no broken functionality:

- Layout renders correctly (split-panel, header, CSS scoping all intact)
- Threads API returns 11 threads (1d) / 15 threads (7d)
- Session tails, attach, Linear sync, update, delete — all 200
- Time window selector (1h → 7d) works correctly
- No fixes were required

**Non-blocking observations noted:**
1. Several orphaned component files (`ChatReply.tsx`, `NewChatBar.tsx`, etc.) are unused — chat input is inline in `DetailPanel.tsx`
2. A past butler null error appeared in logs from ~23:07 last night — already fixed by existing `Array.isArray` guard
3. Sharp adapter warning is cosmetic, not a runtime issue
