All clear. Palace Mail passed the full audit.

**What was tested:**
- Layout: header with owner tabs (Junwon/Ace), account pills (manglasabang, palace.fund, palacering), split inbox/detail pane, compose button, folder tabs
- API endpoints: inbox (all 6 accounts), message detail, search, attachment, VAPID key
- Interactions: owner tab switching, account pill switching, compose modal, reply pre-fill, forward pre-fill, thread grouping
- Error handling: bad account, missing params

**Result: No bugs found. No fixes applied. No rebuild needed.**
