Palace Code tested. Here's what was found:

**Layout & APIs: All passing**
- Page loads correctly with title, split-panel layout, time window selector, and new chat button
- 14 threads returned from `/code/api/threads`
- 5 session tail entries from `/code/api/session-tails`
- 74 Linear issues from `/code/api/linear-issues`
- All other endpoints (attach-thread, update-thread, delete-thread, transcribe) responded correctly

**Bug found and fixed: `thread-store.ts` missing status values**

`ThreadData.status` type was missing `"queued"` and `"archived"`, causing TypeScript errors:
- `chat-stream.ts` sets `status: "queued"` on new threads
- `chat.ts` sets `status: "queued"` on new threads  
- `update-thread.ts` accepts `"archived"` as a valid status

Fixed in `/Users/ace/palacering/apps/palacecode/src/lib/thread-store.ts` — added both values to the union type.
