## Self-Heal Summary

The agent completed a full audit of Palace Code. Here's what was found and fixed:

**Everything working:**
- Page renders correctly at `/code/`
- "Palace Code" title present
- Split-panel layout (thread list + detail panel) properly structured
- Time window selector (1h, 6h, 12h, 1d, 3d, 7d) present
- New chat Plus button present
- All CSS variables defined
- All API endpoints responding correctly:
  - `/code/api/threads` — returns threads
  - `/code/api/session-tails` — returns session logs
  - `/code/api/linear-issues` — returns issues
  - Update/delete/attach endpoints — respond properly

**One bug fixed:**

In `Dashboard.tsx` line 147, `handleDraftSent` was setting the selected thread key as `web:${threadId}` instead of `code:${threadId}`. Since all threads use `channel: "code"`, this caused newly-sent threads to never appear as selected in the detail panel after sending. Fixed to use the correct `code:` prefix.
