Palace Mail is fully operational. Here's what was tested and passed:

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

**API Endpoints** — all working:
- Inbox for all 6 accounts
- Message detail (with and without attachments)
- Attachment download
- Search
- Archive and Delete

**Functionality** — all working:
- Owner tab switching reloads inbox
- Account pill switching updates compose From dropdown
- Folder tabs (Inbox/Sent) work correctly
- Compose modal opens with correct fields
- Reply pre-fills To and adds "Re:" prefix
- Forward clears To and adds "Fwd:" prefix
- Thread view loads all messages in parallel
- Swipe-to-archive and swipe-to-delete gestures work
- Search with debounce works

No bugs found, no fixes needed.
