**Palace Mail self-heal complete — all tests passed.**

Here's what the agent verified:

**Layout:** Header with Junwon/Ace owner tabs, account domain pills (manglasabang, palace.fund, palacering), split list/detail pane layout, compose button — all rendering correctly.

**API endpoints (all passing):**
- `/api/mail/inbox` — 6 accounts tested, INBOX and Sent folders
- `/api/mail/message` — email detail with subject, from, to, html body, attachments
- `/api/mail/search` — text search working
- `/api/mail/attachment` — downloads with correct content-disposition

**Functionality:**
- Owner tab switching reloads correct inbox
- Account pill switching updates inbox
- Compose opens with correct To/From defaults
- Reply pre-fills To + "Re:" subject
- Forward pre-fills "Fwd:" subject + quoted body
- Swipe-to-archive and swipe-to-delete with undo timer
- HTML emails rendered in Shadow DOM with night-mode support

No fixes were needed. Palace Mail is fully operational.
