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.

- 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.

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.
