Palace Code audit complete — **everything is working**. Here's the summary:

**Layout:** Renders correctly with full split-panel layout, Palace Code title, thread cards (3 threads in last 24h), time window selector (1h–7d), and new chat button all present.

**APIs:** All 9 endpoints tested and passing — threads, session-tails, linear-issues, attach-thread, update-thread, delete-thread, sync-linear, chat-stream validation.

**No fixes needed.** Two known pre-existing non-issues remain (the `sharp` warning from `@astrojs/node`, and Postgres ECONNREFUSED from usage tracking — both handled gracefully).
