All clear. Palace Code self-heal audit passed:

**Tested:**
- Page load and layout (title, split panel, header)
- All 9 API endpoints (threads, session-tails, linear-issues, attach-thread, update-thread, delete-thread, sync-linear)
- Component architecture review (Dashboard, ThreadCard, DetailPanel, StatusBadge, all hooks)
- Redis thread store operations

**Result:** No issues found. Everything working as expected.
