**Palace Code — All Clear**

Ran a full self-heal pass. Every feature tested, nothing broken:

| Test | Result |
|---|---|
| Page layout & rendering | Pass |
| Thread list API (`/code/api/threads`) | Pass — 8 threads in 1d window |
| Session tails API | Pass — 5 entries returned |
| Linear issues API | Pass — 74 issues, 21 active |
| Thread attach/update/delete | Pass |
| Time window selector | Pass — correct counts per window |
| Status validation | Pass — rejects invalid values |

No fixes needed. The service is running cleanly.
