All clear. Palace Code is fully operational:

- **Layout**: Page renders correctly with proper split-panel structure
- **Threads API**: Returns 2 threads, all data intact in Redis
- **Session logs**: Loading correctly for specific threads
- **Linear issues**: 74 issues synced
- **Attachments**: 7 entries, read/write working
- **All mutations**: update, delete, attach all return 200

Nothing broken, no fixes needed.
