Extend the integration suite (now 22 tests) to cover:
- All Mail view (04): single-account merge of Inbox + custom folders with
Junk excluded, and cross-account aggregation across every logged-in account.
- Message actions from the list context menu (05): mark read/unread, delete
(→ Trash), mark-as-spam (→ Junk) and not-spam round-trip, verified on both
the UI counters/row state and the server mailbox the message ends up in.
- Shared/delegated folders (06): a delegated folder (+ Trash/Junk) shared
alice→carol; the shared folder renders with its counter, and read/unread/
delete/spam performed there land correctly (server-verified).
Hooks added: data-testid on context-menu delete/spam/read-unread items
(via a testId prop on ContextMenuItem), data-shared on folder rows, and
testId/data-expanded on sidebar section headers to drive the Shared section.
Observations surfaced by the suite (asserted server-side / with a reconcile):
- mark-as-spam doesn't optimistically decrement the *source* counter the way
delete does; a visibility reconcile settles it.
- shared *destination* counters (shared Trash/Junk) don't refresh live —
forceSync reconciles the active account only, not shared accounts.
Add an end-to-end integration harness that runs the webmail against a real
Stalwart mail server in Docker and drives it with Playwright, focused on the
mail/folder synchronisation behaviour (unread/total counters, folder-list
sync, account-scoped Unified Mailbox) that the unified-mailbox work touches.
- integration/ stack: Stalwart (declarative bootstrap: alice/bob/carol,
submission + IMAP listeners, permissive CORS) + webmail (dev mode, so the
browser's plaintext cross-origin JMAP calls aren't blocked by the prod CSP).
- Helpers: dependency-free SMTP submit client, JMAP client for seeding /
inspecting server state, and page helpers (login, add/switch account,
locale-independent folder-counter reads).
- Specs: login, single-account sync (receive/read/move/delete/folder-create/
burst) and multi-account (per-account isolation + cross-account Unified
Inbox aggregation + background-account delivery). 12 tests, all green.
- Add focused data-testid hooks to the mail UI (folder rows + counters, email
list items, account switcher, composer) for stable selectors.
- Exclude examples/ and integration/ from tsconfig/eslint/.dockerignore.
