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).

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.

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).
