Twelve mails carried hardcoded English while the app itself has enforced HU/EN parity since E5.
A mail is the one user-facing surface nobody can re-render by switching the UI language: it arrives
once, in whatever language we picked, and stays that way. That made the epic's own headline mail —
"one mail, one click" — English for a Hungarian reader.
The text moved to a catalog (`mailtext.py`) with a `text(key, lang, **vars)` renderer, and the parity
rule is now a test rather than a habit: every key must carry both languages AND the same
`{placeholders}`. A translation that drops `{link}` sends a mail with no link in it; one that invents
a placeholder raises inside a background task nobody is watching. Both are silent in production.
Every `send_*` takes the language as its second argument, resolved by the REQUEST handler and never
inside the mail — these all run as background tasks, after the request's session is gone, which is
the same reason the approval mail computes its link in the handler.
Where the language comes from, in order: the account's own preference; failing that, the language the
person asked us in; failing that, English. The middle one is new — `invites.lang`, migration `0082` —
because the mails an access request produces go to an address that usually has no account yet, and
the signal does exist: the page their form was submitted from, or the locale Google reported for a
sign-in we refused. Captured rather than derived, for the third time in this epic (`google_email` in
S3, `preferences.language` in S6 taught the same lesson): a signal that exists only in one moment
cannot be backfilled later. So the admin is asked in exactly one place — the invitation to an address
they typed in themselves, where nobody has ever told us anything.
That send is now a dialog rather than a bare click, which is also where the "you already wrote to
them" warning belongs — it used to live only in a tooltip the admin may never hover, guarding the one
action whose failure mode is mailing a real person twice.
S6's registration `lang` field turned out to be dead on arrival: the backend accepted it, the
frontend never sent it, so every account has been storing nothing. The request builders now stamp the
UI language themselves — a signal that has to be passed in by every caller is one every caller can
forget, which is exactly how it shipped unset.
Admins are notified one mail per language group instead of one blast to everyone. They are people
with their own UI language; a single message would have to pick one of them and be wrong for the rest.
Also removes a duplicated `invited_at` column declaration on `Invite` (two identical definitions
landed in S6).
Round 3's correctness/security pass came back clean; what was left said more than
the code does.
- emailOff promised the access-request list is where sign-ups show up. A sign-up
on an address that is already approved or already pending adds nothing to it
(roadmap UX-25), and "only" was falsified by this release's own inbox notice.
- deleteConfirm claimed the admin was dropping "an approval you already gave" —
it is the confirmation for pending and denied rows too.
- sendFailed blamed the mail server for rejecting a message; the reason covers
connect, DNS, TLS and login failures alike, so it now describes the symptom and
leaves the diagnosis to the log.
- ADMIN_EMAILS re-promotion happens in the Google callback only, not on any
sign-in.
Tests: the decided-list copy of the delete affordance was never rendered (both
new cases fail if that branch is dropped), and the throttle release — a
deliberate behaviour the notes advertise — was asserted by nothing; a drop with
no admin yet, or with a failing write, must not silence the following hour.
Three operator gaps, all found the same way — a person could not sign up and the
app showed nobody anything.
- DELETE /api/admin/invites/{id} with a delete control on both the pending
requests and the previously-decided list. Deny keeps the row so the person
cannot immediately re-ask; delete forgets the address. Refused with 409 while
a User row exists for it, because is_allowed reads that row and removing it
would revoke a live user's access with no other sign — the list ships
has_account so the UI withholds the button instead of offering one that fails.
- Email is fail-soft by design, which had come to mean invisible. _send() now
records an email_undelivered notification for every admin when a message is
skipped or rejected, naming the message that was lost, throttled to one an
hour. /api/me carries email_configured, driving a standing warning on
Configuration → Email / SMTP and above the access-request list.
- The sign-in card's Create account / Forgot password / Didn't get the email
views are history entries (useHistorySubview), so Back returns to the previous
view instead of only moving the address bar.
Also: the per-test rate-limiter reset sweeps every loaded app.* module rather
than a hand-kept list of three — this change added a limiter outside it.
