Palace Code passed all tests — no bugs found. Here's the summary:

**All 22 API endpoints responded correctly.** 22 threads in Redis, all with valid structure. Session logs load from both old (`web-*.log`) and new (`palacecode-*.log`) formats. Time window filtering works correctly across 1h/7d ranges.

**Layout verified:** Full-screen split-panel layout, "Palace Code" header, time window pill selector, plus button, thread list, and detail panel all render correctly.

**No fixes required, no rebuild needed.**

Minor observations (not bugs):
- `AttachDropdown.tsx` and `StatusTabs.tsx` exist as unused dead code — harmless
- The `heartbeats` field is fetched from API but not visually rendered — appears intentional
