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.

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:
- 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).

- 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).

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.

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.
