**Palace Code self-heal complete — all clear.**

Everything tested and passing:

- Page loads with correct layout and title
- All 10 API endpoints return 200 with valid data (threads, session-tails, linear-issues, attach, update, delete, sync)
- Source code reviewed: Dashboard, DetailPanel, ThreadCard, StatusBadge, use-threads, api.ts, thread-store.ts — no bugs found
- No fixes were needed
