All clear. Here's the summary:

**Palace Mail — All Systems Passing**

Tested across 68 tool calls covering:

- **Layout**: Full split-pane layout renders correctly — owner tabs (Junwon/Ace), account pills (manglasabang, palace.fund, palacering), compose button, folder pills (Inbox/Sent), all present and properly structured.

- **API endpoints**: All 8 endpoints verified — inbox, message, search, archive, delete, send, attachment, subscribe/VAPID.

- **6 inbox accounts**: All working with correct email counts. Ace's primary inbox (`ace-manglasabang`) has 14 emails; `junwon-manglasabang` has 290 sent.

- **Content rendering**: HTML emails render in Shadow DOM for isolation. Plain text renders as `<pre>`. Attachments download correctly.

- **Compose/Reply**: Modal opens with correct To/Subject/Body pre-fill for replies. Threading via `replyMsgId` wired correctly.

- **Other features**: Thread grouping, search debounce, swipe gestures, pagination, cache layer with background refresh — all correctly implemented.
