Palace Code self-heal audit complete. All 10 checks passed — no fixes needed.

**Summary:**
- Page loads correctly at `/code/` with full layout (header, split-panel, thread list, detail panel)
- All 11 API endpoints returning expected responses
- 1 thread in Redis, 5 session log entries, 74 Linear issues loaded
- No console errors (only the recurring benign `sharp` warning)
- Dead code in `NewChatBar.tsx` and `ChatReply.tsx` noted — harmless, not bugs
