**Note on tests 9-10:** `scale_action_log` only has 19 days of history (data starts 2026-07-11), so 30/60/90d windows all return the same 85 records. This is correct behavior, just not different from each other.

## 🐛 Issues Found & Fixed During Testing

### Issue 1: JS error on first load
- **Symptom:** `TypeError: Cannot set properties of null (setting 'textContent')` in recs section
- **Root cause:** HTML had `id="kVerdictDetail"` but JS tried to set `kVerdictDelta.textContent` (which didn't exist)
- **Fix:** Removed `kVerdictDelta.textContent = '';` line (the empty string was unnecessary)
- **Status:** ✅ Fixed and verified (0 JS errors on second test)

### Issue 2: `kVerdictDelta` element doesn't exist
- **Symptom:** Stats not rendering after the verdict step
- **Root cause:** HTML and JS were inconsistent
- **Fix:** Removed JS line that referenced non-existent element
- **Status:** ✅ Fixed and verified (all stats render now)
