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).

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.

- 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.

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.
