All clear. Palace Code is healthy:

- **Layout**: Page renders correctly with split-panel layout, header, time window selector, and new chat button
- **APIs**: All endpoints functional — 18 threads loaded, session tails, linear issues, attachments all responding correctly
- **Components**: Dashboard, DetailPanel, ThreadCard, StatusBadge all intact and logically consistent
- **Infrastructure**: Palacering (port 6572) and palacecode standalone server (port 6573) both running, connected to Redis

No fixes were needed.
