All clear. Palace Code passed every test:

- **Layout**: full split-panel renders correctly, all UI elements present (header, thread cards, time window selector, new chat button, status/cost/duration badges)
- **APIs**: all 12 endpoints responded correctly — threads, session-tails (log + transcript fallback), linear-issues, attach-thread, update-thread, delete-thread, sync-linear
- **Functionality**: thread list loads from Redis, session logs viewable, time window selector works, new chat modal opens

No bugs found, no fixes needed.
