All clear. Palace Code is healthy:

- Page loads and renders correctly at `/code/`
- All 8 API endpoints responding properly (threads, session-tails, linear-issues, attach-thread, update-thread, delete-thread)
- 22 threads returned over the 24h window, 5 session tail entries
- Caddy proxy routing is correct (page → port 6572, APIs → port 6573)
- All UI features intact: thread list, detail panel, time window selector, new chat button, swipe gestures, status badges, collapsible session log entries

No fixes needed.
