Security (ultimo-security-report.md):
- Security headers on every response, the app shell included: they lived at
server level and nginx dropped them in any location with its own header.
CSP, framing, nosniff, referrer, permissions (docker/nginx-security.conf).
- Plain HTTP forwarded by the reverse proxy is redirected to HTTPS; HSTS on
HTTPS responses. server_tokens off.
- Cross-site state-changing /api requests refused (login CSRF), WebSocket too.
- Validation errors in the usual error shape, without the request model.
- New-password policy: max 128, common/own-address/repeated refused,
breached-password check (HIBP k-anonymity, fails open).
- Message HTML: links keep only http(s)/mailto (sanitizer v6); the HTML
endpoint carries its own no-script CSP.
- Outbound fetches pinned to the checked IP (DNS rebinding); external
IMAP/SMTP servers re-checked before each connection; CGNAT and mapped
addresses counted as non-public.
Fixes from testing:
- IDLE loop catches up before idling: mail that came while the worker was
away no longer waits up to 10 minutes.
- Restore from Spam/Trash/Archive moves only the removed messages, not your
reply in Sent.
- Narrow desktop list stacks sender/subject/snippet (subject was squeezed
to nothing at the default width), with hover actions.
- Phone: wide emails scale to fit the screen.
- Singular forms ("1 message"); no zip button for a single attachment;
app passwords no longer claim "never used" for mail apps.
- ruff format across the backend.

Branding: the page titles and app name are now "Ultimo Email".
Admin panel (now two columns with a divider):
- Users: search by login or by a mail account's address or name (results
only, nothing listed until something is typed). A user opens a window to
change their quota, block/unblock them, or delete them; block and delete ask
for confirmation, and an admin cannot do either to their own account.
- Blocking (users.blocked_at, migration 0019) refuses sign-in with a clear
message and revokes every session; a new user.signed_out event sends the
user's open tabs to the sign-in screen at once. Any "not signed in" answer
now does the same, not only /auth/me. Deleting removes mail accounts (sync
stops), plugin rows (cleared inside the user's RLS context, since plugin
tables have no FK to users), blobs, the search index, sessions and the user.
- Outgoing system mail (migration 0020): SMTP server, port, security, login,
password (vault-encrypted, never sent back), From address and the public
address reset links point to, plus a "Send test" that reports the server's
error.
Password reset:
- "Forgot password?" on the sign-in page asks for the user name and always
answers "If this account exists you will receive an email to your recovery
email address"; the mail goes out after the response, so neither the reply
nor its timing reveals an account, and it is capped at 3 per hour.
- The emailed link (token in the URL fragment, single use, 30 minutes) opens a
page to set a new password. With 2-step verification on, the code is checked
before anything changes; five wrong codes burn the link.
- Settings > Profile: the recovery email can be added, changed or removed,
confirmed with the current password, which must be typed — autofill and
paste are refused (TypedPasswordInput).
Also adds frontend/icons/ultimo-logo-bimi.svg, an SVG Tiny PS version of the
logo for a BIMI record.

Each owned account is tiered by the coordinator; the runner shapes its work to
match — correctness identical, only latency/socket cost differ.
- hot: persistent INBOX IDLE + secondary poll every POLL_WARM.
- warm: no persistent socket; transient INBOX+special poll every POLL_WARM.
- cold: same transient poll every POLL_COLD.
- engine: poll_all_loop (transient full poll); secondary_poll_loop interval is
now a parameter; POLL_INTERVAL removed in favor of POLL_WARM/POLL_COLD.
- coordinator: tier eval every 120s from session heat (sess:active:{user}) +
recent mail (max internal_date within TIER_HOT_ACTIVITY_H), with the
HOT_BUDGET_PER_WORKER guard shedding least-recently-active session-less hot
accounts; user.active event promotes a user's accounts to hot at once (≤5s).
- API: login + WS connect/ping publish user.active and refresh sess:active
(TTL TIER_SESSION_GRACE_MIN). New sync:tier:{id} key, default warm on claim.
- config: POLL_WARM/POLL_COLD/TIER_*/HOT_BUDGET_PER_WORKER.
- tests: 5 tier tests (session/recent-mail promotion, cold, user.active,
budget demotion) alongside the lease/lifecycle acceptance tests.

- Coordinator subscribes to account.state_changed over Redis pub/sub: going
live marks the account claimable at once; disabled/deleted/error tears the
owning runner down immediately (≤30s) instead of waiting for the lease TTL.
- delete_account now publishes account.state_changed:deleted after dropping the
account from sync:live, so teardown is event-driven, not just fencing.
- AccountRunner gains a verify loop (defense in depth): it periodically confirms
the account is still live and flags itself dead if not; the coordinator reaps
dead runners and releases their lease. Zombie loops are structurally impossible.
- New core event user.active (SPEC §8.3), published on login and on every WS
connect; consumed for tier promotion in step 5.
- Acceptance: added event-driven teardown test (isolated from fencing/verify).
