Sending: a send the server could not take (unreachable, timeout, 4xx) is no
longer failed at once. It waits in Scheduled ("retrying") and is tried again
after 1, 2, 5, 10, 30 min, then hourly, for 24 hours — on the server, so it
works with the browser closed. A permanent refusal (5xx, wrong password) is
"failed" at once, with the server's reason. GET /outbox lists both;
POST /outbox/{id}/retry (Retry now) and /cancel (Edit, Delete) act on them,
and they are left out of Drafts. Mail delivered but not filed in Sent now
counts as sent, and a conditional claim keeps two jobs from sending one
message twice. The app says when a send failed and when it finally went.
Actions: arq retries a job only on Retry, never on a plain exception, so the
"retry x5, then revert" for flags and moves never happened. Flag, move,
archive, restore, delete and empty-folder jobs now raise Retry while the
server is unreachable (~24 hours of growing gaps), skip a change a later one
replaced, stop at the first connection failure instead of 20 s per message,
and delete/empty keep the rows until the server has the messages gone.
Account health: 3 failed connections in a row mark an account unreachable
(amber in the sidebar and Settings, cleared on the next success); 3 refused
sign-ins stop its syncing as auth_failed until the password is entered
again, so the provider does not lock the account. Sync loops back off 30 s
doubling to 10 min and log one line per expected failure; a refused
connection fails at once with its reason (the connect task is kept), and a
silently dead IDLE connection is noticed within ~11 min instead of ~29.
Also: the empty reading pane is clipped to its width when dragged very
narrow; tests no longer leave live accounts and outbox rows in the database.
Migration 0021: outbox attempts / next_attempt_at / retry_until, accounts
sync_error / sync_error_since.

Compose, Reply and Forward work offline. Drafts are kept on the device
(IndexedDB, lib/scheduled.ts), with files attached offline; Send becomes
"Schedule" and puts the message in a new Scheduled folder. When the server
is reachable again, scheduled messages are sent through the normal outbox
(Undo offered for a single one) and offline drafts become server drafts —
files uploaded first, each step recorded so nothing is created or sent
twice, under a Web Lock so two tabs never send the same message. Drafts
written offline show in Drafts as "On this device". Sign-out sends what
is scheduled, then wipes the device's copy.
Also: offline failures from keyboard shortcuts show "Not available
offline"; no recipient suggestions are asked for offline; a reply no
longer quotes an error page when the original is not saved.
The undo countdown counted to the server's deadline on the browser's
clock, so a few seconds of skew showed (18 s instead of 10). /send now
also returns undo_seconds, and the composer counts down from that.

A self-hosted LanguageTool (dev: docker/docker-compose.yml, started by
`make up`) checks what the user writes in the compose window, through
POST /api/spellcheck — the browser never talks to the engine directly.
- Marks are CSS highlights over the text, never written into the message: red
wavy for spelling, blue for grammar/style. Clicking one shows the message,
up to five suggestions (applied as typed, so Ctrl+Z undoes them) and Ignore.
The popup, like the link popup, opens above its anchor when there is no
room below.
- Checked after a pause in typing; the signature and quoted original are
skipped; marks on words just edited drop at once; a check overtaken by a
newer one, by turning checking off, or by closing the window is discarded.
- With "auto", text is checked in chunks of lines, each in its own detected
language — LanguageTool settles on one language per request, so a mixed
Polish/English message had every English word flagged as a Polish typo.
- Settings > Appearance: on/off and language (Auto-detect or any of the
engine's languages); the compose window's More menu overrides it for one
message. The browser's own spellcheck steps aside while ours runs, and comes
back when it is off or the server has no engine (503 from the endpoint).

System mail: the password-reset email (and the admin panel's test email) now
opens with the Ultimo logo, centered. It is a PNG rendered from
icons/ultimo-logo.svg and embedded in the message (multipart/related, cid:),
so it shows where remote images are blocked and in clients that do not
render SVG. The PNG is listed in package-data so the Docker image carries it.
Trusted devices: a 2FA sign-in offers "Don't ask for the code on this device
in future". Ticked with a correct code, the browser gets its own HttpOnly
trusted-device cookie (token in Redis, 90 days, renewed on use); later
sign-ins to the same account from that browser need only the password. Other
accounts and browsers are unaffected. The trust is revoked on a password
reset, when 2FA is turned off, and when an admin blocks or deletes the user;
signing out keeps it.

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.

A missing avatar was a 404, which the browser reports as an error for every
such sender on every page. It is now an empty 204: the <img> still fails to
decode it and the initials show through, but nothing is logged, and the miss
carries the same one-day browser cache as a hit so it stops being re-fetched.
On a phone the mail list's rows sit 20px apart instead of 7px.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The shared Redis client decodes replies as UTF-8 text, but the avatar cache
holds raw image bytes and a b"none" miss marker: an image could not be read
back at all, and a miss came back as str and crashed on .partition(b"\n").
Only a sender's first request worked; after that, a 500. The cache now goes
through a binary-safe client, get_redis_bytes().

<title> is not an allowed tag, so nh3 unwrapped it and kept its text —
"mailer", "Email template" or the subject rendered before the content.
It is now dropped with its content, both in the sanitized HTML and in the
text derived from HTML-only mail (snippet and search). SANITIZER_VERSION
goes to 4 so stored bodies re-sanitize from the raw blob on next render.

The sender column showed participants[0], and participants are rebuilt
newest message first — so replying to a thread put the user in that slot
and the list named them instead of the person who wrote in.
Thread summaries (list and search) now carry `senders`: the distinct From
addresses of the thread's visible messages, oldest first, with the same
Trash/Spam visibility as the message count. The list joins them and shows
the user's own account addresses as "me" ("me, Alice" for a thread the
user started), and the avatar prefers the other side of the conversation.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The first column listed a thread's `participants`, which the threader builds from
from + to + cc — so every ordinary email read "Sender, You", and the +N badge
beside the avatar counted the user themselves.
`participants` cannot simply be narrowed: the subject-fallback join matches an
incoming message's recipients against it (threader._by_subject), so dropping
recipients would change how mail is threaded. Hence a separate `threads.senders`,
holding only from addresses, newest writer first — which is also the right thing
for a conversation where several people replied.
Migration 0019 backfills it, so existing threads do not wait to be touched again.
The list falls back to `participants` if a row somehow has no senders, rather
than rendering an empty column.

Reported from the running app: a message showed as unread in the list — bold,
blue dot — while the reading pane showed it as read, and only a manual "mark as
read" reconciled them.
The two views read different things. The pane reads the message's own flags; the
list reads `threads.unread_count`, denormalized from them. `apply_delta` updated
message flags with a bare UPDATE and never recomputed the thread, so a flag set
anywhere but in this app — read on a phone, filed by a server-side rule — moved
one and not the other. Auto-mark-on-read could not fix it either: it sees a
message that is already \Seen and correctly does nothing, leaving the counter
wrong forever.
Expunges had the same hole, which also left `message_count` overstated.
`apply_delta` now collects the affected threads and re-denormalizes them after
the deletes, so a thread emptied by an expunge is removed rather than recounted.
Migration 0018 repairs rows that already drifted — recomputed from the messages,
so it is a no-op on a healthy database. One thread was stale here; installs that
have been syncing longer will have more.

Warming Bayes hung on a single event — `account.state_changed` reaching "live".
That covers an account added from now on and nothing else. An account that went
live before this plugin existed never gets one; neither does one whose Junk
folder was empty at the time and filled up later, or one whose owner enabled
spam-folder sync afterwards. A worker restarting at the wrong moment loses it
too. The result was a feature that quietly required someone to run it by hand
per account, which is not a feature.
An hourly sweep now walks every live account and offers each a bootstrap. That
works because the per-account job was already cheap to repeat: it returns at once
for an account already done, and declines — without marking it done — when the
corpus is still too small to learn from. So the sweep simply keeps asking until
there is something worth learning, then does it once.
`s.accounts.live()` is the new SDK surface it needs: cross-user by design,
because a sweep runs for the instance rather than a request. Ids and state only,
so reading anything still goes through the user-scoped accessors.
One failing account cannot stop the sweep — the mailbox that raises is logged and
the rest still get their turn.
docs/plugins.md now says this in general terms next to `JobSpec`: a state-change
hook is one-shot, so pair it with a sweep when the work must eventually happen
for everything.

"Mark as Spam" moved the message but left it on screen. Two causes, both fixed
generally rather than for this one action.
`move_job` published message.changed without a thread_id, so the WS handler
invalidated the message list but never the thread the user was reading — the
panel had no reason to refetch. It now names the thread.
And a thread whose last visible message has gone should not linger. MailLayout
closes the panel when the open thread comes back empty, whoever emptied it —
core action or plugin.
`move_to_special` now also publishes the move immediately rather than waiting
for the IMAP job, since a plugin acting on the user's behalf has no client-side
handle to update optimistically the way the core endpoint's caller does.
That exposed an ordering bug: the optimistic event reaches the passive-learning
hook, which would re-teach the lesson /learn had just taught. /learn now records
`learned` before moving, so the hook's dedup stands down — and records it with
an upsert, because provider-filed spam has no verdict row of ours to update.
One real mistake on the way: the event first reported the destination folder as
the source, which would have made every move look like a no-op to anything
reading the pair.

A button pinned to every message header is a persistent control; marking spam is
a verb you reach for occasionally, like Reply or Delete. It now lives in the
Actions menu, between Labels and Delete.
That needed a slot inside the dropdown, which the catalog had no name for:
`message.actions.menu`. The host wraps it so any click closes the menu, leaving
a bundle to do nothing but act.
The UI kit gains `.wm-menu-item`, @applying the exact utilities ThreadView's own
menu items use — the same trick the sidebar shell already relies on, so a plugin
verb is indistinguishable from a core one rather than approximately similar.
Labels follow the folder as before: "Mark as Spam" in the inbox or archive,
"Mark as not spam" in the spam folder, nothing in Sent/Drafts/Trash. A message
already taught shows that, disabled, instead of offering the lesson again.

Explicit teaching shipped with C1 (the Spam / Not spam buttons). This adds the
two halves that need no buttons at all.
Passive learning (§C.5). Moving mail into Spam says "this is spam" more honestly
than any button, because the user is doing it for their own reasons rather than
to train a filter; moving it back out says the opposite. Only those two
transitions teach — Spam to Trash is someone tidying up, Inbox to Archive says
nothing about spam. Teaching the same message the same thing twice is skipped,
since users move things back and forth, but reversing a lesson is allowed. If
the engine is down nothing is recorded, so a later move can teach it again.
This needed the transition, not just the destination: `message.changed` carried
only where a message landed, so `move_job` now also publishes
previous_mailbox_id and both special_use values.
Provider bootstrap (§C.5). An account going live enqueues a job that teaches
Bayes from mail the user already owns — up to 500 messages from the provider's
Junk folder as spam, and up to 500 Inbox messages older than 30 days as ham.
This is the constructive use of the history that classification deliberately
refuses to act on: the same backfill, read instead of judged. It sleeps between
messages so live classification never queues behind training, stops rather than
grinding if the engine disappears, and marks the account done in KV so it runs
once.
That needed `PluginMessages.sample`: the SDK could fetch a message by id but not
enumerate a folder. Ids only — bodies are pulled one at a time, so a 500-message
sample never materialises 500 bodies.
Verified against the running engine: teaching moved its `learned` counter 0 -> 2.

Plugin settings pages were stacked at the bottom of Settings -> Accounts, which
put antispam's thresholds and lists under a heading about mail accounts. Each
`settings.page` now gets its own entry in the Settings nav: "Antispam filtering"
and "Mail filters".
Slot gains an optional `title` for this — the host needs a label when it gives a
slot an area of its own, and falls back to the plugin name. PluginSlot gains an
optional `plugin` filter so a host can render one plugin's bundle rather than
every binding for a slot name.
Wording: the app calls that folder Spam (i18n `nav.spam`), so the plugin's copy
now does too — "filed into Spam", "Move to Spam", "marked as spam". The IMAP
special-use stays `junk`, which is what the protocol calls it; only what the
user reads changed.

message.new fires for imported history as well as new arrivals, and EventBus
awaits hooks inline. As written, adding an account would have scored every
message in its backfill — filing years-old inbox mail into Junk on the server,
and adding ~70 ms of serialized HTTP per message to the backfill loop (twelve
minutes on a 10k-message account). It is also when the filter is least able to
judge, because Bayes has learned nothing yet.
The envelope now carries account_state, and the hook returns unless it is
"live". The backfill window belongs to the C2 learning bootstrap (§C.5), which
reads that history as training data instead of acting on it.
Tests pin the gating: backfilling accounts are not even read from the blob
store, non-inbox folders are ignored, a live inbox arrival still classifies, and
an unreachable engine still delivers.

Three additive surfaces the antispam plugin (M7, Appendix C) needs and the
frozen §11 API did not have. None of them changes a core mail path.
`actions.move_to_special` moves ONE message into an account's folder by
special-use, wrapping the same optimistic-update + move_job path the core
endpoint uses. The existing `trash` moves a whole thread, which is right for
Delete and wrong for a spam verdict: one spam reply must not drag a legitimate
conversation into Junk. It returns False rather than raising when the account
has no such folder — an account whose server lacks a Junk folder must still
receive its mail.
`messages.raw` returns the stored RFC822 bytes. Spam scoring needs headers and
body; the SDK could only hand out one header at a time.
`envelope` now also carries account_id and mailbox_special_use. Appendix C must
classify only inbox arrivals, and neither the message.new payload nor the
envelope previously said where a message landed.
docs/open-questions.md gains OQ-6 (why these are additive rather than a spec
violation of "zero core diffs") and OQ-7 (why the engine is reached with plain
httpx instead of the SSRF-guarded sdk.http).

Three strands that only make sense together, so they land together.
Registration gate (migration 0016). POST /auth/register was open to anyone
who could reach the port. Now the first account on an empty instance is
always allowed, becomes the administrator, and closes registration behind
itself; after that it takes an admin reopening it. The decision is made
under a row lock on app_settings so two simultaneous first signups cannot
both see an empty table and both claim administrator. Existing installs
keep their oldest account as admin and start closed.
Instance default quota (migration 0017). users.quota_bytes is snapshotted
at creation from app_settings.default_quota_bytes, so changing the default
affects later accounts only and never resizes a mailbox that exists.
The panel is a separate app, not a page in the mail client. admin.html is
its own Vite entry (5.8 KB next to the client's 1.7 MB; they share only the
vendor chunk), with its own administrator sign-in. One nginx now serves two
listeners: :80 is the mail client and 404s both /admin.html and
/api/admin/*, :81 is the panel. docker-compose publishes them as WEB_PORT
and ADMIN_PORT. The boundary is nginx refusing paths on one listener, not
process isolation — CurrentAdmin still guards every admin route — so
ADMIN_PORT must be restricted to the LAN, which the runbook now covers for
both DSM and QNAP.
Also QNAP: deploy/webmail.sh finds Container Station's docker under
/share/*/.qpkg/container-station/bin, which is off an SSH session's PATH,
before anything shells out to it. docs/nas-install.md gains a QuTS hero
runbook (§2.6), splits the DSM firewall section into container-to-container
(§8.1) and the egress case that makes account-add time out while
autodiscovery appears to work (§8.2), and scopes both to Synology.

Everything needed to run the app on an Intel NAS that is also doing other
jobs: one published port, no host networking, memory/CPU caps and log
rotation on every container, and all state in bind mounts under DATA_ROOT
so mail survives image updates, project deletion in the NAS UI, and full
reinstalls — and so Hyper Backup/HBS3 can actually see it.
- docker/Dockerfile.backend: multi-stage, non-root (uid 10001), tini for
the <10s graceful lease release. Installs the four plugins as entry-point
distributions. One image, several roles via docker/entrypoint.sh
(api | worker-sync | worker-jobs | migrate | reindex | plugins).
- docker/Dockerfile.frontend + nginx.conf: SPA + /api reverse proxy with
the WebSocket upgrade for /api/ws, and X-Forwarded-Proto preserved so
the API still emits __Host-/Secure cookies when TLS is terminated by
the NAS reverse proxy (identity/cookies.py keys off request scheme).
- docker/docker-compose.prod.yml: project name webmail-prod, NOT webmail —
docker-compose.yml (dev services) owns that name, and two compose files
sharing one project name fight over each other's containers.
Meilisearch is an opt-in profile; SEARCH_BACKEND=pg is the default so a
small NAS pays nothing for search.
- migrate runs as a one-shot (core Alembic head + every plugin branch)
that everything else waits on, so a bad migration can never leave new
code running against an old schema.
- docker/backup.sh: nightly pg_dump verified with `pg_restore --list`
before it counts as a backup, with retention and a baseline on first
start.
- deploy/webmail.sh: init/doctor/up/down/status/logs/update/rollback/
backup/restore/reindex/psql/shell. `update` is backup -> images ->
migrate -> roll workers, api, web -> health-gate, with automatic
rollback to the previous version if the gate fails. `doctor` refuses to
be quiet when DATA_ROOT is on NFS/SMB (silent Postgres corruption).
- deploy/build-push.sh: build images off-NAS (the frontend build wants
~2GB RAM) and push to Gitea, or --save a tar to carry over.
- scripts/reindex_search.py: rebuild the search index from Postgres alone.
Every SearchDoc field is already stored, so the index is derived data
that never needs backing up — this closes the only real objection to
running Meilisearch on a box whose volumes may be wiped.
- pyproject: package-data for accounts/presets.yaml and the shared plugin
Alembic env. Without it a non-editable install (i.e. any image) silently
ships a package that fails at runtime.
- GET /api/version, used by the deploy health gate.
Verified end to end on a real stack: fresh install, all services healthy,
core + 4 plugin migration branches applied, login/SPA/plugin bundles
through nginx, WS upgrade returning 101, __Host- cookies under a
simulated TLS proxy, backup -> restore round-trip preserving user and
plugin schema, failed-update auto-rollback (both a bad migration and a
boot-crashing API), and Meilisearch profile serving a live query.
ruff + mypy --strict clean, 363/363 backend tests pass.

Sender avatars (privacy-safe, server-fetched, cached):
- New GET /api/avatar resolves Gravatar (d=404) then the sender domain's favicon
under the SSRF guard, Redis-cached (hit+miss); gated by SENDER_AVATARS_ENABLED.
GuardedResponse gains raw bytes. Shown in the mail list, reading pane, People
panel, and Contacts (overlay that falls back to initials on a miss).
PDF preview:
- Password-protected PDFs now prompt in-place and retry (pdf.js PasswordException),
with a clear error for other load failures instead of a blank overlay. The
password is remembered per attachment until the thread is left; clicking the
field no longer dismisses the overlay.
Contacts:
- Autosave reply recipients: message.sent now carries to/cc (name+email); the
contacts plugin subscribes and adds any non-contact recipients to the Autosaved
group. Contact avatars show the gravatar/favicon via /api/avatar.
Mail views / retention:
- Clicking an account shows all its mail except Trash/Spam (was inbox-only).
- Daily cron autopurge_trash_spam permanently deletes Trash/Spam older than
TRASH_RETENTION_DAYS (default 30; 0 disables) — server EXPUNGE + local rows.
UI polish:

Gmail sync (SPEC: Gmail sync):
- Provider fetches X-GM-LABELS when X-GM-EXT-1 is advertised; parses custom labels
(system labels dropped, mUTF-7 decoded) onto RemoteMessage.
- Engine syncs only system folders + All Mail for Gmail, skips every label folder,
and dedupes the All Mail pass by Message-ID — kills the INBOX/All-Mail duplication.
- Custom labels ride the message.new event; the labels plugin subscribes and maps
them to chips as "<name> [Gmail]" (per-message + thread aggregate + known set),
so labels fill in gradually with the sync window. Non-ASCII labels decode right.
Labels self-healing (message-driven reconcile):
- Per-message keys are the source of truth; t: aggregates and _labels are derived.
Reconcile drops labels of deleted messages, regroups survivors by their current
thread (fixing JWZ thread merges), rewrites changed t: keys, and rebuilds _labels
from live messages — keeping user labels, dropping orphaned Gmail ones.
- New SDK reads: sdk.threads.existing / sdk.messages.threads_of. Sidebar refreshes
live via a plugin.labels.changed WS event on new labels.
Account deletion: prune threads left empty after the cascade (they were user-scoped,
so only messages cascaded) + de-list the account from surviving cross-account threads.
Sync SPAM: opt-in per-account sync_spam (migration 0015, default off) — the engine
skips the Junk folder in backfill and poll unless enabled; wizard checkbox added.
Robustness / UX:
- WebSocket auto-reconnects with backoff and resyncs on (re)connect, and account
add/delete invalidates threads/labels — no more hard refresh for live updates.
- Backfill banner + sidebar ring also require done < total, so a completed account
can't leave a stuck "X of X".
- Scrub lone UTF-16 surrogates from parsed headers/bodies so bad messages no longer
crash the backfill on Postgres text/JSONB.
- Ultimo signet logo in the Mail/Calendar/Contacts sidebar header (and at the top of
the collapsed rail), via the shared plugin-ui.css + MailLayout.

Implements SPEC v1.5 §6.2.1–6.2.3 so Gmail (and Yahoo/iCloud/Outlook-personal)
onboard via a provider app password on the existing plain-password sync path —
no OAuth, no new sync code. Gmail was oauth2-only with OAuth unimplemented, so it
was previously un-addable.
Backend:
- presets.yaml: each preset declares an ordered `auth_strategy`; Gmail becomes
`auth: password` + `[app_password, oauth2]`. App-password providers ship a
data-driven `help:` block (deep_link, app_name_hint, i18n step keys, docs_url).
- discovery/types: CandidateConfig carries `auth_strategy` + `HelpBlock`; presets
load them and autoconfig candidates derive a default from the detected auth.
- schemas/api: CandidateOut exposes auth_strategy + help; DiscoverResponse adds
`google_oauth_enabled`.
- config: GOOGLE_OAUTH_ENABLED flag (default false) gates the OAuth fallback.
Frontend:
- ProviderCredentialPanel (wizard step 1.5): deep-link popup (user gesture),
rendered steps, single paste field that strips whitespace, instant verify
(auto POST /accounts/test at 16 chars → Connected ✓ / mapped error), and the
auth_failed recovery branch with a gated "Sign in with Google instead" button.
- AccountWizard routes app-password providers to the panel, then a details step.
- i18n keys (en) for the panel + provider steps.
Honors the §6.2.2 prohibitions: no page automation, no real-password capture,
no scraping — deep-link + guide + paste + test only. Adds the v1.5 spec.

Labels:
- Moved labelling out of the "+label" message slot into Mail: label chips on the
thread subject bar (removable ✕) and before list subjects, and a Labels submenu
in the per-message Actions menu (multi-select checkboxes + "Create new…").
Per-message storage kept; the reading pane writes a thread-union aggregate so the
list (no message ids) can show chips.
- Sidebar LABELS section rewritten: aligned monocolor tag rows, collapsible
(collapsed by default), inline "+" create popover, hover "−" delete with a confirm
popover, and click-to-filter the mail list by label.
- Backend: batch message/thread label reads, thread aggregate, create + delete
(delete unhooks from all mail), and GET /labels/{name}/threads. Core GET /threads
gained an `ids` param to power the label view. Removed the plugin-pages list from
the Mail sidebar.
Plain-text mail now renders in Lato (self-hosted at /fonts, @font-face'd into the
sandboxed message iframe) instead of the monospace <pre> default.
Calendar right-panel (embed mode): restored the "…" view-options menu, pinned the
toolbar + mini-calendar (only the agenda scrolls), plain "All calendars" button
(inline resets), and the event popover now closes on any outside click.

Mail:
- New "More" (⋯) menu in the list sorting bar with "Mark all as read": POST
/threads/mark-read marks every unread thread in the current view (unified /
folder:<special> / account:<uuid>) as \Seen, pushes + publishes updates.
- Message iframe: no longer shows a spurious vertical scrollbar (display:block,
getBoundingClientRect+ceil sizing, overflow-y:hidden on the doc) and has
rounded corners.
- Deep links from Contacts: /mail?compose=1&to= opens a maximized prefilled
composer; /mail?q= prefills the search box.
Contacts:
- Detail pane shows all populated fields (work subtitle, phones, address, urls,
nickname, birthday). Company name is used as the display name when there's no
personal name (existing rows too). Editable "Add notes".
- Selection: checkbox reveals on avatar hover only; Groups/More bulk menus in
select mode; "N contacts selected" panel; filled yellow VIP star in list +
detail; pagination bottom bar; Lato pinned on form controls.
- Groups: "+" on the GROUPS header and "Create new" in the group menus (bulk
add/remove via POST /groups/{id}/add|remove, ownership-guarded).
- Rounded Mail-style list rows; removed the ⋯ button from the search bar;
Compose→Mail, Find-all-conversations→Mail search; Message button removed;
delete confirmation; resizable sidebar + list/detail split.
Calendar: the right panel (agenda / search) is now resizable.

Calendar settings (Settings > Calendars):
- Reminders are now {method, minutes}: Add-reminder opens a boxed form with a
method dropdown (Show an alert / Email me) + time dropdown, bell icons.
Backend normalizes the legacy list[int] transparently.
- New Invitations section (auto-add emailed events): policy radios, "Add new
events from" (My contacts / Anyone), "Add to calendar", mark-read+file toggle.
Persisted to user settings (inbound iMIP processing still deferred).
- Time zone options show GMT codes, e.g. "Central European Summer Time (GMT+2)".
- Default calendar now defaults to "Personal" instead of a generic placeholder.
- Colour picker is a circular-swatch-only dropdown (sized so swatches don't overlap).
- Delete calendar / remove subscription now confirm via a modal.
- Create form: dropped the breadcrumb; heading stays "Create calendar" even after
a Publish toggle auto-creates the calendar.
Publish links: replaced the 244-char vault-sealed token with a 16-char random
slug (secrets.token_urlsafe). New sdk.public_session() (privileged, non-RLS) lets
the public /public/{token} feed resolve the slug directly with explicit filters.
Settings shell: "<- Mail" is now a context-aware "<- Back" via ?from=; Calendar
opens Settings with from=/p/calendar so Back returns to the calendar.

Calendar plugin (webmail_plugin_calendar, non-removable core plugin):
- Local calendars/events CRUD with RLS isolation; recurrence expanded at
query time (DST-correct), EXDATE + detached-override merge.
- Calendar app bundle: month/week/day/3-day views, mini-month, event form
(color, show-as, timezone combobox, repeat, reminders, guests w/ recipient
autocomplete, Jitsi video call), event popover with RSVP badges, resizable/
collapsible left panel + theme toggle, overlap layout.
- iMIP invites: sdk.mail sends REQUEST from the organizer's mailbox (HTML +
text/calendar + invite.ics); public /rsvp endpoint (vault-sealed token)
records accepted/declined/tentative per attendee.
- "This and following" edit + scoped delete (this / this-and-following), with
a delete confirmation dialog for recurring events.
Core:
- Settings: time_format (12/24h, default 24h) + jitsi_server; new Integrations
section; date order follows time format (en-GB vs en-US) across Mail.
- Plugin SDK: mail (send from a user's account), vault (envelope encrypt),
multi-method SSRF-guarded http; AppSwitcher product switcher; full-bleed
PluginPage.
Mail HTML rendering:
- Sanitizer allows <style> blocks + class (CSS sanitized: drop script-like,
strip @import/url() when remote images blocked); SANITIZER_VERSION 3 so
already-indexed mail re-sanitizes on view.
- Attachments: a Content-Disposition: attachment part is a real attachment
even when it also carries a Content-ID (fixes hidden invite.ics).

Server-side deletions now propagate to the DB. Previously poll() detected new
messages and CONDSTORE flag deltas but never expunges (the old TODO), so mail
deleted in another client lingered as phantoms outside the small Drafts reconcile.
- provider: enable QRESYNC when advertised (_maybe_enable_qresync + qresync_enabled
property). poll() harvests VANISHED (expunged UIDs) and changed FLAGS in one pass
via a raw `SELECT <mbox> (QRESYNC (uidvalidity modseq))` — issued as a low-level
SELECT because aioimaplib only surfaces untagged VANISHED lines on a sync command,
not on an async UID FETCH. CONDSTORE-only servers (e.g. Gmail) keep the CHANGEDSINCE
flag delta and fall back to the engine reconcile.
- parsing: parse_vanished() for `VANISHED [(EARLIER)] <uid-set>` with range expansion.
- engine: apply_delta now drops expunged rows from the search index, un-links any
local draft mirroring a vanished UID, and publishes message.deleted for the UI.
- tests: parse_vanished unit cases + apply_delta expunge (removal, draft un-link,
modseq advance).
Verified live: the worker issues `SELECT "INBOX" (QRESYNC (uidvalidity modseq))`
against QRESYNC-capable accounts. ruff + mypy --strict clean; 296 tests pass.

Frontend:
- Full-screen attachment preview overlay (AttachmentPreview) for image/pdf/txt
plus office docs: .docx via docx-preview (rendered live into the sandboxed
iframe so header/footer VML images survive), .xlsx via xlsx-preview, and
.odt/.ods/.odp/.odg via a JSZip+DOMParser ODF walker (officeConvert).
- Type-aware attachment icons (green spreadsheet, blue document, red PDF,
image/archive); new document/image/spreadsheet/print SVGs.
- Composer: drag-drop attachments (body drop inserts images inline, else
attaches); inserted images are selectable/resizable/deletable (RichTextEditor).
- Undo-send: "Sending…" banner with live "N seconds to Undo" countdown.
- Search result list: pin/archive/delete update correctly; grey-out only for
search hits; scoped "Search in Trash/Spam".
Backend:
- Search: prefix (search-as-you-type) matching, email-address search, and
address-first result ordering; Trash/Junk excluded with scoped folder search.
- Attachments: RFC 6266 Content-Disposition for non-ASCII filenames; one-time
inline image loading.

Claude-Session: https://claude.ai/code/session_01Rcj3TpydMTzTSmU7kunzf8
Search (PG backend):
- '@' terms match address substrings (from/to/cc), so a partial email like
"dyrektor@wfdif" resolves and narrows predictably as you type
- index each address split into parts, so a bare domain/local word ("wfdif")
finds the address (indexed as one lexeme otherwise); dotted terms fall back to
an address substring
- rank sender/recipient name+address matches above body/subject-only ones
(addr_hit tier, then recency); cursor extended to keep keyset pagination correct
- scripts/reindex_address_parts.py backfills address tokens into existing rows
Inline images:
- extract attachments via a full MIME walk instead of shallow iter_attachments(),
which missed inline images nested in mixed>related>alternative (cid: rendered
broken); has_attachments counts only real (non-cid) attachments
- scripts/backfill_inline_attachments.py stores previously-missed inline images
Folder-name i18n (SPEC §12 M2):
- accent/punctuation-insensitive, multi-delimiter (/ \ .) special-use inference
across ~13 languages; curated names (no substring false positives)
Link security (reading panel):
- links never navigate the message iframe: a parent-side click interceptor opens
http/https in a new tab (noopener) and mailto in the composer (recipient
pre-filled); all other schemes blocked
Backend 292 tests green, ruff + mypy --strict clean; frontend tsc/eslint/vitest clean.

Search:
- Meilisearch backend (app/search/meili.py) + factory wiring; pinned SDK 2.7
- Search-as-you-type: debounced query + Postgres prefix matching, built from
the DB tokenizer so full email addresses match (email stays one lexeme)
- Saved searches API + sidebar virtual mailboxes; save affordance in the box
Account sync windows (SPEC §12 M2):
- Choose at setup: All (recent 30d first, then remainder), Last 3 months, New only
- Per-account sync_window + "Sync remaining mail" from settings (idempotent re-run)
- Provider windowed backfill (SINCE/BEFORE), message_count, newest_uid
- migration 0012: accounts.sync_window + backfill_total/backfill_done
Backfill progress UX:
- Floating progress card (auto-dissolves after 10s) + spinning sidebar ring that
fills with the account colour; driven by sync.progress over WS
Thread list pagination:
- Server-side offset + accurate grand total, with filter/order in SQL; working
prev/next across all synced mail
Reading panel:
- "Load images" one-off now actually renders images (?images=1) without trusting
the sender; envelope carries images_allowed so a trusted sender shows no prompt
Threading:
- Subject fallback no longer merges messages that declare an explicit (different)
parent; true siblings still group via a shared-parent reference match. Fixes
unrelated auto-replies with the same subject landing in one thread
Backend 257 tests green, ruff + mypy --strict clean; frontend tsc/eslint/vitest clean.

Backend:
- Collapse identical cross-account deliveries in a thread: new messages.delivery_id
(migration 0011) preserves the real Message-ID even when message_id_hdr is
synthesized (§7.1); get_thread groups by it and reports also_in_account_ids; the
list count counts distinct deliveries. Backfill script for existing rows.
Frontend:
- Bundle Lato (SIL OFL) as the UI font; unread mail-list rows use Black weight.
- Mail-list selection: hover-avatar checkbox, tri-state "select all", bulk
Archive/Pin/Delete (Restore/Delete in Archive/Trash/Spam) with a count in the
reading pane; unread blue dot; "also delivered to" note in the thread.
- Spacing/size tuning: sender-column width, icon gaps, avatar size, bar heights,
and a round of -1px font sizes across the sidebar, mail list, and reading pane.

Claude-Session: https://claude.ai/code/session_01U72FZiF1W1pb8XxyWBTREA
Backend:
- Restore returns each message to its original folder (e.g. Sent/Archive) instead
of always the Inbox: new messages.restore_mailbox_id (migration 0010) +
restore_thread_job.
- Drafts: expunge reconciliation for the Drafts poll (provider.list_uids /
_reconcile_drafts) clears phantom "remote" drafts; send + discard drop the
mirrored DB row; adopting a remote draft carries its real attachments into the
compose flow.
- Thread detail/list are folder-aware: individually trashed/spam messages are
hidden outside their folder, Trash/Spam show only their own messages, and the
mail-list message count matches the view.
Frontend:
- Thread reading panel: fix newest-first card overlap/spacing (expand-all and
single expand), hide Reply/Forward on trashed messages, close the Actions menu
on message-body (iframe) clicks, scroll to the inline composer, and prompt
Save draft / Discard on the X close.
- Composer: remount when switching drafts, dirty-tracking to stop duplicate IMAP
mirrors, and close the From/More dropdowns on outside click.
- Sidebar: collapse/expand toggle (icons-only ~60px rail) and a log-out icon on
Sign out.
- Mail-standard printing in a new window with reliable page margins (lib/print.ts).

Rework the conversation view to match the new dark-theme mockups:
- Subject bar gains a print button and an expand/collapse-all toggle (default
action expands all; collapsing leaves only the newest message open).
- Collapsed messages are compact single-line cards (40px avatar, colored sender
name, snippet, relative date) that overlap into a stack; alignment follows the
sort order (top edge for oldest-first, bottom edge for newest-first) and the
always-open newest card overlaps its neighbour in both orders.
- Expanded messages show sender+address (whole header row toggles collapse), a
detail disclosure (From/To/Cc/Subject/Date/Size), the message location
(Inbox/Sent), a read/unread circle (per-message flag toggle), a quick
Reply/Reply-all, and an Actions menu (reply/forward/print/delete). The
Reply/Reply all/Forward bar now sits inside the newest card above a divider.
- Message body: the quoted original is hidden by default with a "•••" toggle
injected after the "On … wrote:" attribution; the iframe now collapses-then-
measures so it shrinks back when the quote is hidden.
- Avatars use the sender's IMAP-account colour when the address matches one of
our accounts, else a stable per-sender hue; two initials for multi-word names.
- Brighter dark-theme border token; new print/expand-all/collapse-all icons.
Backend: add size_bytes to the message envelope (shown in message details).

- loadtest/soak_sync.py + mock_provider.py: fully isolated soak for acceptance
criterion 7. Creates a throwaway webmail_soak DB + uses Redis DB 14 (both torn
down), simulates N accounts (default 1000, 20% active sessions) across 3
in-process coordinators with a mock MailProvider (no real IMAP). Asserts:
all accounts owned, persistent sockets <= hot*1.05, oldest lag < POLL_COLD*1.15,
RSS stable. Steady state = after every account has completed its first sync.
Configurable via SOAK_* / POLL_* env for fast smoke runs.
- engine: poll_all_loop and secondary_poll_loop now jitter their waits (first at a
random point in the interval, later +/-10%) so a fleet claimed together doesn't
poll in lockstep — anti-thundering-herd, a real improvement surfaced by the soak.
Validated: 60-account smoke passes all four criteria; full gate green (238 tests).

- Heartbeat JSON now carries {owned, sockets_open, tiers:{hot,warm,cold}, ts} per
§2 so peers and operators can see each worker's load and socket footprint.
- run.py runs the sync coordinator directly (not via a placeholder arq worker) so
SIGINT/SIGTERM can stop the claimer, cancel runners, and release every lease
explicitly within a 10s drain budget — peers adopt the accounts immediately
instead of waiting out the lease TTL. Removed the sync:control-queue hack and
the supervisor indirection (start/stop_supervisor, sync_on_startup/shutdown).
- Acceptance: graceful-shutdown test proves a peer adopts released accounts within
seconds under a 30s TTL (i.e. via release, not expiry).

- concurrency.loop_semaphore: per-event-loop semaphores (safe across pytest loops
and process restarts via a WeakKeyDictionary keyed by the running loop).
- provider: holds a per-account (≤4) and per-host (PER_HOST_CONN_CAP) slot for the
whole lifetime of an IMAP socket, released on close; SMTP send takes a per-host
slot for its duration. A worker can no longer open hundreds of sockets to one
host/account.
- indexer: parsing goes through a PARSE_CONCURRENCY semaphore, and a message over
STREAM_PARSE_MB is parsed from its blob file (parse_message_file) instead of an
in-memory tree, so peak RAM ~= PARSE_CONCURRENCY x STREAM_PARSE_MB regardless of
mailbox sizes. Backfill parallelism stays bounded by the bulk queue only.
- config: PER_HOST_CONN_CAP, PARSE_CONCURRENCY, STREAM_PARSE_MB.
- tests: per-account cap blocks the 5th connection / distinct accounts independent;
file-vs-bytes parse equivalence + large-message streaming routing.

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).

Ownership of an account now moves through a Redis lease so any number of sync
workers can run against the same account set with no double-IDLE.
- leases.py: sync:live registry + sync:lease:{id} (SET NX EX) with owner-checked
Lua renew/release; mark_live / mark_not_live helpers.
- coordinator.py: SyncCoordinator claims from sync:live up to MAX_ACCOUNTS_PER_
WORKER, renews every LEASE_RENEW (fences the runner on lease loss), reconciles
sync:live against Postgres, heartbeats a worker key, and rebalances when it
holds well above a fair share.
- supervisor start/stop now drive a coordinator; engine._set_state and
delete_account maintain sync:live membership (+ lease drop = fencing teardown).
- config: MAX_ACCOUNTS_PER_WORKER, LEASE_TTL, LEASE_RENEW.
- tests: acceptance 1-3 (single ownership, crash failover, create/delete
lifecycle) driving the real coordinator + Redis with faked IMAP loops.

Move the per-account INBOX-IDLE + secondary-poll loops out of the supervisor
into a self-contained AccountRunner (start/stop/teardown). The startup supervisor
now launches one runner per live account. Pure refactor, no behavior change.

Backend
- Sent copies: persist locally on send + periodic multi-folder CONDSTORE poll
(Sent/Archive/Trash/Junk) so they thread and show without an IDLE-only INBOX.
- Bcc: transmitted copy omits Bcc, Sent copy keeps it; store/display bcc_addr.
- Drafts: mirror local drafts to the IMAP Drafts folder (append/replace/expunge);
inbound sync of foreign drafts (un-threaded) with adopt-to-edit + dedup by UID.
- Per-user storage quota (5 GiB default) and manual "sync all folders" action.
- Account editing (display/color/server/password) and per-account HTML signature.
- Account view scoped to that account's inbox; new migrations 0006–0009.
Frontend
- Mail-list pagination, folder filters (All/Unread/Pinned), sort toggle, refresh.
- Aligned + widened mail-list margins; reading-pane bars fixed height.
- Rich-text composer: color palette, highlight, image; attachments; expand/pop-out.
- Signatures: auto-insert for new mail, replace on From change, reply insert.
- Restore/Delete actions per folder; drafts view merges local + remote, date-sorted.
