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.

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.

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).

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.
