peter 6b0401b922 fix(logs): rule on every swallowed exception in the backend
114 exception handlers neither logged nor re-raised. The defect was never that
they are silent — plenty of them should be — it is that their silence said
nothing, so nobody could tell a decision from an oversight. Each one has now been
read. 44 got a line; the other 70 carry `# silent-ok: <why>`.

What the silent ones had been hiding, in the cases that got a line:
- A failed ffprobe sent every HDR file down the 8-bit pipeline, so playback
  degraded to a software transcode with nothing saying why; a failed audio probe
  collapsed a multi-audio file to one track and the player showed no language
  picker; a failed first-PTS probe left subtitles seconds out of sync.
- A subtitle sidecar that existed but would not parse made a PARTIAL track read as
  complete, permanently — the viewer loses every cue past the cached window.
- An unreadable crop/trim/cut-list in an edit spec was dropped, so the clip came
  out uncropped, untrimmed, or shorter than the one the user built.
- A dropped `max_height` downloaded at best quality against an explicit cap.
- A failed videos.list enrich made every candidate undroppable-from-judgement and
  therefore dropped: a working search rendered as "no results".
- An unusable password hash answered as "wrong password", locking the owner out
  and telling them they mistyped; a rotated TOKEN_ENCRYPTION_KEY turned every
  stored token into "not connected".
- A stored admin setting that would not coerce fell back to the env default while
  the settings page went on showing the saved value.
- A one-off InnerTube config failure pinned the whole process to the hard-coded
  fallback key, and searches return nothing when that goes stale.
- The HLS sweep reported 0 swept — like a clean run — when it could not list its
  own root, leaving every crashed session's segments on disk forever.

Four of them are counted rather than logged per item (dropped cues, dropped cut
list segments, unreclaimed GC files) and reported once per call, because the
alternative is one line per cue over a whole subtitle track.

ruff gains S110 and BLE001. Every blind `except Exception` that remains carries
`# noqa: BLE001 — <why>`, which is the point: catching everything is sometimes
right, and always worth a sentence. plex/sync.py's three best-effort backfill
catches now keep the traceback — a blind catch over a batch that fetches AND
writes could be Plex, the database or our own bug, and `%s` of the exception told
them apart badly. main.py's boot-time log-level read likewise.

logs.event's `code` is positional-only now: `event("x", code=...)` was a TypeError,
and `code` is exactly the word a caller reaches for when the thing that failed has
one of its own.

tests/test_swallowed_exceptions.py is the wider rule ruff cannot see: a handler
that neither logs nor re-raises must say why. Both cases mutation-checked — a
marker removed and a log line removed each fail it, naming the handler.

peter dc221338be fix(logs): keep what a person typed out of the backend log lines
The E22 redactor is a safety net over addresses and credential params, and every
one of these call sites was leaning on it to do the whole job. What it does not
cover went in whole, and what it does cover came out as a constant.

Not covered, so a real leak:
- routes/search.py logged the raw search term at ERROR. The privacy policy shipped
  in 0.88.0 says a search string is kept only at Teljes/TRACE, with the user's own
  consent. The ERROR line now carries the shape of the failure (source, candidate
  and collected counts) and the term follows on a TRACE line, which nothing emits
  unless that consent is in force.
- downloads/backfill.py logged the full source URL at INFO — a row of the user's
  download history. Now the asset id and the host.
- youtube/client.py logged the upstream error body, which is prose that quotes the
  request back. Every failing YouTube call now goes through one _upstream_failure()
  that logs the API's `reason` code, keeps the body for the same consented TRACE
  line, and raises a YouTubeError carrying `reason` as a field — callers put that
  error in log lines of their own (routes/channels.py) and in a 422 answered to the
  user, so the body must not travel in it either.

Covered, so merely useless: routes/auth.py named the account by an address that
reached both sinks as `[email]`, and app/email.py printed recipient lists that read
as `['[email]']`. Both now carry the uid (or a count) and a reason code, which is
also the first half of E22.5 S4's failed-sign-in coverage.

routes/channels.py branched on the text of that error message to recognise an
already-existing subscription. It now branches on `exc.reason`, with the substring
check kept beside it for a body that carried no reason at all.

tests/test_log_pii.py pins the call sites and the family: a source-level contract
test walks every log call in app/ and fails on an argument naming user-typed
content unless the line says why it is safe (`# log-pii-ok: <why>`). Eight sites
carry that marker today, each with its reason. Gate 8/8 green; all five cases
mutation-checked.

peter 11aef4ab7a feat: record when an account last signed in
users.last_login_at (migration 0085, no backfill) is stamped by _establish_session,
which the Google callback now shares with password login instead of repeating its
session setup inline. The demo entry does not stamp its shared account. The admin
user list carries the field.

peter 47d968eeea fix: review round 4 — an account switch unloads as the old account, a share link's lockout costs five networks
Deep-review round 4, targeted at round 3's changes (f569b19c..e7f38396).

Accounts
- Switching, adding or signing out an account moved the tab's pin before
  the page unloaded, so the players' resume beacons fired on the way out
  under the NEW account: one account's playback position saved into the
  other. The pin is now handed to the next page (pinOnNextPage) and taken
  over at import; clearActiveAccount is gone.
- Switching to a suspended account was refused but left it in the
  switcher, refused on every click; a deactivated one was not refused at
  all, and made the default it signed every account in the browser out on
  the next request. Every account _session_user would refuse — gone,
  deactivated, suspended, revoked — is refused and dropped from the list.

Share page (/watch)
- An IPv6 client is limited by its /64 (client_ip becomes client_key, for
  every limiter): keyed on the full address, one subscriber could rotate
  through endless identities. The comments now state what the per-link
  ceiling costs: guessing from five networks can keep a link shut for its
  window, and guesses already running when it fills are still checked.
- The link is looked up before the limiter records the attempt, so made-up
  tokens no longer grow it by an entry each.

Forms
- Failing the same way twice is announced again: the sign-in, passphrase
  and setup errors are keyed on the attempt (a clear and a set in one
  handler left the alert node untouched).
- The install wizard's own validation showed the generic error — it threw
  plain objects its catch did not read. It sets the step's message.

Tests: a re-pin leaving the previous account's notices behind; the pin
hand-over; switching to an ended account; the /64 viewer; made-up tokens;
the repeated alerts. Each mutation-checked RED for its own reason.

peter e7f38396a2 fix: review round 3 — a new tab keeps its account's notices, a revoked tab account lands on the default
Deep-review round 3 over main..improvement/watch-background-audio.

Account boot
- The notification history and settings, and the hints toggle, are read
  when their modules load, which in a new tab (bookmark, typed URL) is
  before BootGate pins the account: they read as nobody's, and the tab's
  first notice replaced the account's stored history (up to 100 entries)
  with a one-item list. They now read again when the tab is pinned
  (onAccountPinned, run by setActiveAccount); a notice raised before the
  pin stays, after the history.
- A tab pinned to an account still in this browser's wallet but whose
  session ended (suspended, deleted, or revoked by "log out everywhere")
  got "signed out" from /api/me while the default account was still
  signed in, and signing in again as anyone else left it there. A refused
  per-tab account now leaves the wallet, and the probe answers as the
  default, so the tab reloads onto it.

Share page (/watch)
- The password unlock is limited per viewer (link + client IP), under a
  per-link ceiling that counts only wrong passwords. Keyed on the link
  alone, ten wrong guesses every five minutes locked out every viewer,
  the ones with the password included. client_ip moves to app.ratelimit
  so the public routes can key on it.
- Its failure messages and the load-failure screen are announced
  (role=alert, the password input described by its error). The sign-in,
  passphrase, password-change and setup form errors get role=alert too.

Comments that still described removed machinery are corrected: App's
collapse flags, SettingsPanel's Save bar, ConfigPanel, authed_format_sig.

Tests: the account's history and hints across the pin; a revoked and a
suspended pinned account; the per-viewer limit and the ceiling; the
limiter's exhausted(); the share page's announced failures; a share
link's feed filters persisted. Each mutation-checked RED for its own
reason.

peter f569b19c49 fix: review round 2 — a signed-out tab acts as nobody, honest share-page failures
Deep-review round 2 over main..improvement/watch-background-audio.

Account resolution (server)
- A request naming an account that is no longer signed in to this browser
  (X-Siftlode-Account or ?account=) now acts as nobody instead of the
  session's default account. A tab still pinned to an account signed out in
  another tab went on acting as the default: its player checkpoints and
  preference saves landed in that account, the messages socket and Plex
  playback ran as it, and its Sign out signed THAT account out. A hidden tab
  never polls /api/me, so a tab playing in the background kept doing it.
  The /api/me bootstrap probe alone keeps the fallback, which is how such a
  tab learns who it now is: the app's 401 handler reloads, and BootGate
  re-pins the tab.

BootGate
- On an identity change the tab reloads without moving its pin first. The
  tree being torn down still runs its unmount saves before the page goes,
  and with the pin already moved they wrote into the new account's local
  keys (a player volume still pending). The reloaded page corrects the pin.

Share page (/watch)
- Only a 404 says the link is gone. A 5xx, a dropped connection, and the
  unlock's own rate limit all rendered "no longer available ... expired or
  revoked" to a viewer with a valid link, with no way to try again. A load
  failure now offers Retry; too many password tries says so and keeps the
  form; an unlock that gets no answer says so instead of doing nothing.
  Strings in en/hu/de.

Downloads
- A cookie-authed asset is recognised under the current signature version
  and the one before it, so a job queued before a deploy that bumps the
  version still downloads with its cookie instead of failing on the login
  wall with an error that says no cookie was used.

The app chunk is preloaded through lazyWithPreload, so a failed fetch no
longer leaves an unhandled rejection beside the ErrorBoundary. The panel
layout seed is one helper (seedLayout).

Tests: the stale-tab refusal, its harmless Sign out and the probe fallback;
the pre-bump authed asset; BootGate keeping the pin on reload and staying
mounted through a same-account change; the reveal clock's later-commit
hand-off; the prefs, panel layout and demo-scope seeds from the me cache;
the share page's failure states. Each mutation-checked RED for its own
reason.

peter a0114deff1 fix(api,ui): a refused write says why, wherever the refusal happens
Round 5 taught `notifyActionError` to discard a plain-string `detail` in favour
of the caller's translated fallback, because `req` leaves 403/404/429 to the
caller and those routes hand-write English. Three places did not get the
message.

**The demo account lost its explanation.** `require_human` refused with a plain
string, so from that commit on the shared demo account got its caller's generic
"couldn't do that" and no hint that the demo account was the reason — and the
gate is not backed by a UI gate everywhere: the comfort shelf has no `is_demo`
check, so the pin button is live and simply fails. A structured `{code: "demo"}`
and an `errors.demo` string in both locales. The two auth routes that hand-roll
the same check were swept with it.

**`ChatThread` carried a second copy of the contract.** It filtered 404/429
itself and then did `e.detail || t(…)`, the pre-fix order, so the central fix
could not reach it and "That member hasn't set up messaging yet." stayed English
under a Hungarian UI. It goes through the shared helper now, and a contract test
pins the remaining raw-`detail` consumers as an explicit SET — never a count —
so a new copy fails the gate instead of shipping. The five on that list are
inline surfaces (a form field's error line, a setup banner) and are deferred
with the ~60 backend routes whose details they print.

**The Plex "Add to playlist" dialog was still silent.** Same shape as the
collection editor round 5 fixed and the YouTube twin that already had the fix:
no catch, so a playlist deleted on another device answered a structured 404 that
nothing reported — the tick never flipped, the gone row stayed, and the floating
promise became an unhandled rejection.

Also: the `ABORTED` sentinel's VALUE was asserted nowhere. The consumer test
hand-built the error it expected, so replacing `xhr.onabort`'s rejection with a
friendlier message left the lane green — and every upload the user cancels would
then raise a red "the upload failed" toast, which is what the sentinel prevents.
Both producer tests assert through `isAborted` now.

And two backend tests were pinning fewer sites than their own docstrings claimed:
the channel-404 loop said "all five" and issued three requests (explore and
subscribe unexercised, the excuse for subscribe naming a different call site
with a different reason slug), and the recipient/job test named three refusals
and requested two — `share_download`'s `not_found("recipient")` had no test in
the suite at all, nor did the locale keys added beside it. Every site named now
has a request behind it.

6 tests, mutation-checked against 7 mutations: the demo detail at both the gate
and an auth route, a re-hand-rolled ChatThread, the silent Plex dialog, the
abort sentinel, and each unpinned 404 — all red on the test that names them.

peter f98b060e2b feat(admin): an account panel, and a set-password link that needs no email
Design option C, chosen by the user 2026-09-05. Nothing in the admin UI
ever showed an account's GATE STATE: an admin could see a "Pending
approval" chip but not whether the address was confirmed, whether SEC-10
had cleared the password, or which Google account was attached — so
every support conversation started by guessing. Clicking a row now opens
a drawer that says which gate the person is actually stuck behind, with
the recovery actions under that readout rather than in the row.

The drawer is `Modal placement="drawer"`, not a second dialog: the layer
stack, ESC, the focus trap, Back-to-close and the scroll lock are the
hard parts, and duplicating them is how two shells drift apart. It
slides in, and honours prefers-reduced-motion like the rest.

The link itself (SEC-15, SEC-16, and the everyday "no SMTP and someone
forgot theirs") reuses the existing token machinery and the SAME
`#reset=` entry the mailed link uses, so the signed-out card consumes it
with no new flow. It is a distinct token KIND for one reason: a mailed
reset arrives in the mailbox, so completing it proves ownership and
confirms the address; an admin-issued link proves nothing about the
mailbox — the admin hands it over by whatever means they choose — so it
must not satisfy the email gate. Claiming otherwise would be the same
false attestation SEC-15 is about.

Issuing does not revoke the current password: a misclick must not lock
anyone out. USING it rewrites the hash and bumps the session epoch,
which is what evicts a squatter — SEC-16's actual remedy. Spending
either kind burns the siblings of both, so a completed reset cannot
leave a live admin link behind. The non-consuming probe learned the new
kind too, or every admin link would have opened onto "this link is
spent". The audit log records that a link was issued, by whom, for whom
— never the link, which is a live credential-setting secret and the last
thing that belongs in a long-lived log a human reads.

Not gated on account state on purpose: it is useful for a pre-empted
address, a revoked password, a Google-only account that wants one, and a
plain forgotten password. Narrowing it would only make it refuse exactly
when the admin needs it. The shared demo account is the one exception.

Verified on localdev, both languages, end to end: issue from the panel
-> the signed-in tab shows the honest "reset links open in a signed-out
window" banner with the token still in the address bar -> signing out
draws the "Set a new password" form, which is only possible because the
probe recognises the new kind. Gate: pytest 925 -> 942, vitest 676.

peter 540ca244c8 revert(auth): the newest registration does not own an unverified account (E9.5 review round 2)
Round 1 fixed the address pre-emption chain by letting a later registration replace the password on
an unverified account and delete its outstanding verify tokens. Round 2 read that code and showed it
was worse than what it fixed, so it goes back out.

It closes nothing. The rule is symmetric and an attacker can simply register last — on a timer,
inside the five-per-five-minutes budget — while the owner registers once. What it does add is two
primitives an unauthenticated caller did not have: overwrite a real registrant's chosen password,
and delete the confirmation link already sitting in their inbox (the approval mail's 7-day token is
an ordinary verify token, so the blanket delete took that too). Worst of all it fired on the rows
SEC-10 left stripped — password_hash NULL, password_revoked_at set, active — installing an
attacker's password where the entire state means "there is none", and clearing the stamp that is the
only reason password-reset still accepts them. That is a straight takeover which did not exist
before, in the code written to prevent one.

The owner's recourse needed no new primitive and already worked: password-reset accepts a
pre-empted account, proves the mailbox, rewrites the hash and bumps the session epoch. What remains
is the bounded window between a confirmation click and that reset, which is SEC-16 — logged with
this attempt written down, so the next person does not reach for it again.

Two smaller round-2 findings go with it. `upsert_pending_invite`'s new exact-spelling tie-break ran
before any status preference, so it could deterministically pick a DENIED sibling over a pending one
and reopen it — the very outcome its comment claimed to prevent; the status preference now comes
first. And `send_invitation` activated the account before the send it might have to report as
failed, so a request the UI called a failure had quietly let someone in; activation now follows a
mail that actually left. The verify token minted to render that mail still commits either way — it
is single-use, expires on its own and was mailed nowhere, and the note says so rather than leaving
the next reader to wonder whether it was missed.

peter 563fa0513d fix(auth): close what the epic's own review found (E9.5 review round 1)
Eleven findings survived adversarial verification; these are the fixes.

**Address pre-emption.** S1 dropped the approval-time password revoke, arguing `password_login`
refuses an unverified account before it reads `is_active`. Two verifiers showed that holds only
while the address stays unverified — and S6's approval mail exists to get the real owner to end that
state, at which point the squatter's password works. While an address is unverified the NEWEST
registration now owns it: the password is replaced and every outstanding verify token deleted, so
the owner takes the row back simply by registering, and a link already in flight cannot confirm it
for anyone else. The residual (an owner who confirms and neither registers nor resets) is logged as
SEC-16 beside SEC-15, where the re-attestation path it needs already lives. The comments that
asserted the old, false invariant now say what actually guards this.

**The entry URL.** S2 moved `clearEntryUrl()` out of the signed-out auth card into a hook App mounts
unconditionally, and it blanket-stripped the whole query string, the fragment and `history.state` on
the FIRST commit. That broke first-run setup outright — the wizard mounts only after its query
resolves and then finds no `?token=` — and silently ate `?link=`/`?oauth=` (no toast, no refetch
after connecting Google), `?v=`/`?chan=` deep links, and scroll restoration. It now clears only the
fragment and the two one-time flags it owns, and preserves `history.state`.

**The env allow-list.** S3 canonicalised the Invite branch of `is_allowed` and left the
ALLOWED_EMAILS/ADMIN_EMAILS fallback matching literally — the 2026-09-03 lockout with a different
source of truth, plus a shadowing trick where an unauthenticated request under a sibling spelling
permanently masked an env grant. Canonical on both sides now, and the same for the delete dialog's
warning and the ADMIN_EMAILS role bootstrap.

**Honest states.** `send_invitation` stamped "I already wrote to them" before a fail-soft background
send; it sends inline and records only what left. The admin-side resend answered `{ok: true}` for a
dropped mail; it now says so. Both also activate/serialize consistently with the other decide paths.

**Correctness sweep.** The 7-day approval link said "expires in 168 hours" — durations render in
days once there is more than one. `_register_account`, `upsert_pending_invite` and `add_invite`
picked among canonical siblings with no ORDER BY and no exact-spelling tie-break, so which account
got the re-send, and whether a denied row was reopened over a pending one, was up to Postgres.
`purge_user` deleted every canonically-equal invite, revoking a surviving sibling account's access.
`ConfirmProvider` wrapped its ReactNode message in a `<p>`. Approving no longer leaves the
stuck-sign-ups list stale. The refusal panels announce and take focus.

**Tests.** Three mailers rewritten this epic never rendered in any test; every `send_*` now renders
in both languages. The orphan-key guard could not fail (it scanned the catalog that defines the
keys) and had no reverse direction. Newly pinned: canonical activation, the surviving sibling's
grant, a failed invitation and resend, an expired reset link, a throttled login's silence, the
per-language admin fan-out, and that the entry URL keeps what it does not own.

peter 10c0ca4cf7 feat(email): write to people in their own language (E9.5 S7)
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).

peter a76bab9b34 feat(auth): one mail, one click — the approval mail carries the confirmation link (E9.5 S6)
The funnel's common ordering made a person open TWO messages: one saying their access was approved,
another asking them to confirm their address. The approval mail now branches on what they actually
still have to do — carry the confirmation link, point at sign-in, or say a confirmation mail follows
once they register — so the usual case is one mail and one click. A mail that guesses wrong is worse
than a plain one: telling someone to sign in while their address is unconfirmed contradicts the
screen that will refuse them.

That embedded link lives 7 days rather than the usual 24 hours. Nobody sits waiting for an approval —
it can easily be read on Monday after a weekend, and an expired link spends the one-mail promise and
puts them back on two. The risk is small: the token only ever confirms an address; it signs nobody in
and sets no password.

The most likely root cause of the 2026-09-03 report that a confirmation mail "never arrived" is here
too, and it was never a delivery failure: re-registering an address that already had an unconfirmed
account returned in SILENCE — same cheerful "check your inbox", no mail sent at all. It now re-sends
the link. Nothing new leaks: the response and its timing are unchanged, and the public verify/resend
already does exactly this for the same input.

Whitelisting stays silent, and that is a decision, not an omission. The operator opens a door as a
possibility — usually already agreed with the person — and a row can sit approved for weeks with
nobody registering; a mail fired automatically there would be nudging someone who never asked.
Telling them is its own act on its own button, `invited_at` records it so a second click is a
decision rather than an accident, and the button only appears where nobody is behind the address yet:
"the door is open, come in" is meaningless to someone already inside.

Two things UAT caught that no test would have. Every fresh registration appeared in BOTH admin lists
at once, because the stuck-sign-ups filter keyed on "unconfirmed" — the rule is now "the address may
sign in, and this account still can't", which leaves an undecided request with the queue that owns
it. And the invitation button was offered on every approved row, half of which are existing users.

Also: the confirmation mail finally says what its link's rules are (once, 24 hours) — the reset mail
always has, while this one left the reader to discover both by meeting a dead link. The card's
"didn't get the email?" moves up under the form, and the three waiting messages name the spam folder,
which is where a first message to a fresh recipient sometimes lands.

Registration now records the language the sign-up page was in. Nothing reads it yet — the bilingual
templates are S7 — but it is the only moment that choice exists anywhere the server can see, and a
preference nobody recorded cannot be backfilled later.

UAT on localdev: re-registering re-sent the link (one token became two, one account); approval issued
a 7-day token and moved the account into the stuck list with only a re-send; whitelisting mailed
nobody; the invitation recorded itself and the row then warned that sending again would write twice.
Test data removed.

peter 7acdf5d577 feat(admin): surface the sign-ups that are stuck outside, and let an admin finish letting them in (E9.5 S5)
Approve an address BEFORE the person registers and their sign-up produces no queue row at all —
`_decide` only takes a still-pending invite — so the Access-requests screen sat empty, the tab badge
read zero, and the only working move was re-typing the address into the whitelist box. Nobody would
guess that, and on 2026-09-03 nobody did.

This is roadmap UX-25, where two earlier attempts were reverted after review. Both moved AUTHORITY:
auto-activating on registration turns a standing whitelist entry into a bearer grant for whoever
registers the address first, and reopening the approved invite to `pending` lets an anonymous sign-up
REVOKE a standing approval. What was actually missing was visibility, so this changes nothing about
what an unauthenticated caller can cause — the admin could already do exactly this by re-entering the
address; they just had no way to know they had to.

The section lists every account that cannot sign in yet and says WHICH gate is shut, because the two
dead ends look the same from the admin's chair: waiting for activation, or waiting on a confirmation
mail. Naming the unconfirmed ones is not decoration — on a no-SMTP instance that is the difference
between the owner and whoever registered the address first (SEC-15), and an admin about to let
someone in should see it. A person the queue above already covers is deliberately NOT listed here;
two buttons for one person is worse than one.

Activate is gated on `is_allowed` — the same function the sign-in paths consult, in core, so the
button that appears and the badge that counts cannot disagree. Without that gate it would
manufacture an inconsistent account: password sign-in only checks `is_active` and would let them in,
while their Google sign-in would be turned away and silently reopened as a fresh access request.
Letting in someone with no approved invite stays the whitelist box's job, which says so out loud.

The badge counts activations SEPARATELY from pending invites rather than widening an existing
field's meaning, and only counts what genuinely waits on the admin: an unconfirmed account waits on
its owner, so it is listed with a re-send but does not nag. The admin-side resend says plainly what
happened, including refusing when the instance has no working SMTP — mail is fail-soft everywhere
else, and that silence is exactly what left the 0.78.5 sign-ups with nothing to fall back on.

`send_verification_link` is now one function with three callers (registration, the public resend,
this one), so the link's shape and TTL cannot drift by who triggered it.

UAT on localdev, both languages: the UX-25 shape reproduced end to end (approve the address, then
register), the badge counting it, Activate letting them in and dropping the badge, the row losing
its Activate but keeping the re-send, a fresh token issued by the re-send, and both actions in the
audit log. Test data removed.

peter b1086e05dc fix(auth): stop drawing a reset form the link can no longer fill (E9.5 S4)
Reported from UAT: delete an account, then open its password-reset link. The card drew the full "set
a new password" form — because a `#reset=` fragment was present, and nothing more — and only after
the user had typed a password did the server answer 400. Measured first: no security hole. A user's
tokens cascade away with the row, so nothing can be set on a deleted or a re-created account. What
was left is a dead end of exactly the kind this epic exists to remove, and it is not rare: a reset
link lives one hour, mail is slow or lands in spam, and whoever got two mails clicks the older one.

password-reset/check answers whether a link is still usable WITHOUT spending it, so asking can never
cost the user their one real attempt — the property the tests pin hardest. It gets its own limiter,
because opening a link must not eat the budget for requesting one, and a throttled caller is told
"ok", never "dead": this check may only ever save someone a wasted form, so when it cannot answer it
degrades to the old behaviour instead of declaring a live link finished. The confirm endpoint stays
the authority, and its failure raises the same named screen, since the token can die between the two
calls or the probe itself may have failed.

A too-short password is deliberately NOT that screen. The length check runs before the token is
spent, so a typo costs the link nothing, and the card tells the two 400s apart by `reason` so only
one of them takes the form down.

Both email-link confirmations (verify, password-reset/confirm) now answer in the {code, reason}
shape S4 introduced. They were the last refusals a user meets by simply clicking an old link while
still being answered in hardcoded English under a bilingual UI. The seven remaining bare strings in
this module (register, request-access, the demo guards, set-password) sit behind client-side
validation the UI does first; they are logged as a follow-up rather than swept in silently here.

One bug found by the UAT itself, in the new code: the check went out FOUR times per opened link —
StrictMode double-invokes effects and the shell remounts the card as the session probe settles.
Harmless per request, but against a per-IP limit it would exhaust the budget in two reloads and then
silently fall back to drawing the form unchecked: nothing errors, the feature just stops working.
Deduped in a module-level map holding the in-flight promise (a ref dies with the remount that causes
it); a failed probe drops itself so a blip is never cached as "dead". The test renders the card
twice, because with one render the guard would rot undetected.

UAT on localdev: the reported scenario end to end (delete the account, open the link) shows the named
screen and no form; a live link still opens the form and completes; the CTA lands on the request-a-
link form; one probe per opened link. Throwaway accounts removed.
2026-09-04 02:38:01 +02:00
peter ed91c83dd7 fix(auth): name the state and the address behind a refused sign-in (E9.5 S4)
"Your account is awaiting admin approval." was true and useless. It never said WHICH mailbox the
account was on, and on 2026-09-03 that silence hid a Gmail alias mismatch for a day: a registration
as np.temu@gmail.com met a Google claim of nptemu@gmail.com, and every screen in the funnel agreed
to say nothing about it.

Every refusal password-login can answer with now uses the codebase's structured {code, reason}
detail, built in one helper. The three that arrive AFTER the password is proven carry the address on
the account plus both gate flags; the two that answer before it (invalid, rate_limited) carry
nothing, so a wrong password and an unknown account stay byte-identical. The frontend renders the
first three as a named screen in place of the form — there is nothing to retype once the password is
correct — with an icon, the two-gate checklist, the address in monospace, and a resend CTA where one
helps. Reporting each gate from its own flag is the payoff of S1: approved-but-unverified is a real
state now, and a screen that assumed a sequence would send that user off to wait for an admin who
has already decided.

The Google access-request notice names the address too, and says so when the request was already on
file under ANOTHER spelling of the same mailbox — the honest version of "we didn't open a second
one", stated only when it applies. It moved from the query string to the fragment: the notice now
carries an address, and a query string lands in every reverse-proxy access log. Same reasoning that
put the verify/reset tokens there, and the same owner already clears it. urlencode, not an f-string,
because URLSearchParams reads a bare + in a fragment as a space and would mangle exactly the
+tag addresses this epic exists to protect.

upsert_pending_invite returns the row it settled on beside the is-new flag, since the row's stored
address is what the notice has to name and what mail will go to.

Deviation from the PendingScreen mockup, deliberately: no "Sign out" button and no separate "Not
your address?" link. The mockup drew the panel in the app shell; the accepted decision (a) keeps the
pending user session-less, so there is no session to end, and the address is named directly above a
"Back to sign in" that answers the same question.

UAT on localdev, both languages: all three refusals with the typed spelling deliberately differing
from the stored one (the panel named the stored one), the resend CTA carrying the typed address into
the resend form, and both access-request banners with a +tag address surviving the fragment round
trip. Throwaway accounts and the language switch reverted.
2026-09-04 01:56:55 +02:00
peter a614ee2435 feat(auth): show the Google address beside the one the account registered with (E9.5 S3)
An account can now hold two true addresses: the one its owner typed, which a Google
sign-in no longer overwrites, and the one Google answers with. Only the first was
stored, so Settings could say 'Connected' without saying connected AS WHOM -- exactly
what someone who registered with a +tag needs to know.

users.google_email (migration 0080) records Google's answer at sign-in and at an
in-app link. /api/me exposes it ONLY when it differs from the account address, so the
comparison lives in one place and the majority, whose two addresses are the same
string, see no change at all. Rendered in the account menu as a muted third line under
the identity, and in the Settings sign-in row under the existing hint.

A short 'Google' label rather than a brand glyph: the app draws one icon set (lucide),
and a generic mail icon next to an email address says nothing. It also reads to a
screen reader, which an unlabelled logo would not.

No backfill is possible -- Google's answer is only known at sign-in -- so accounts
linked earlier stay NULL until their owner next signs in with Google.
2026-09-04 01:23:11 +02:00
peter c74487fbb3 fix(auth): keep the address the user registered with, and let it sign them in (E9.5 S3)
Two halves of one rule: the address someone typed is theirs to keep, and it must be
the one that gets them back in.

A plus-tagged or dotted Gmail is often a deliberate choice -- registering as
me+siftlode@gmail.com is how you find out later which site leaked your address. The
Google callback overwrote it with the account's primary, which can never contain a
'+', so the tag vanished on the first Google sign-in and, because sign-in matched the
stored address, took their chosen address with it. The rewrite line is older than
this epic, but S3 made it reachable here by matching adoption across spellings. It
now runs only when the mailbox GENUINELY changed, and lives in a named helper rather
than inline, so the rule has one home.

The three lookups that resolve a typed address -- password login, password reset,
verify resend -- go through find_user_by_email: exact spelling first, then the unique
canonical candidate, and None when several accounts share a mailbox rather than
guessing which one a password should open. Reset and resend previously answered a
different spelling with silence (they reply uniformly by design), which was a dead end
with no way out. Their mail now goes to the address on the account, never the one
typed into the form.
2026-09-04 01:07:54 +02:00
peter 876cece881 fix(auth): match identity on a canonical email, so one Gmail mailbox is one account (E9.5 S3)
Gmail delivers x.y@, xy@ and xy+tag@ to one inbox; the invite gate only lowercased.
On 2026-09-03 that turned an approved user's Google sign-in into a silent SECOND
access request -- OAuth returns the account's stored primary, which need not be the
spelling they typed -- and left prod with two user rows for one mailbox (ids 13, 14).
The +tag case fails every time: a Google account cannot contain +, so OAuth can only
ever answer with the base address.

Mail still goes to the address AS TYPED; only identity matching uses the canonical
form. utils.canonical_email is the single definition, and a model validator derives
users.email_canonical / invites.email_canonical on every write, so no call site can
forget it. Scope is narrow on purpose: dots are significant on most providers and the
Gmail rule does not hold for Workspace custom domains.

Swept every sibling of the same principle, not just the reported one: is_allowed,
upsert_pending_invite, the Google-callback adoption, _register_account (so no new
duplicate pair can be created), _activate_user_by_email, admin _accounts_for (an
invite backing a live user under another spelling used to look deletable) and
add_invite, plus purge_user, which now erases every canonically-equal invite instead
of leaving one behind that still grants access.

Migration 0079 backfills both columns and indexes them NON-uniquely: prod already
carries canonical duplicates (approved invite pairs since 2026-06-16), and merging
accounts is a judgement call about people's data, not something a migration does on
its own. A test pins the backfill SQL against the Python helper.
2026-09-04 00:14:12 +02:00
peter c134b514c1 fix(auth): confirm an emailed verification link wherever it is opened (E9.5 S2)
The token was only ever consumed inside Welcome.tsx, which App renders ONLY when
there is no session. Opening the emailed link in a browser that already held a
Siftlode session posted nothing, the fragment was then stripped, and the user got
no signal at all -- the link simply did nothing. Incognito worked, which is why it
survived. Confirmation now happens in App, above that branch: signed out the outcome
still drives the auth card's banners, signed in it drives a top-of-app bar.

The entry URL is snapshotted once at import time (lib/entryUrl) instead of per
component, so no future URL writer can strip a token before whoever needs it has
read it -- that ordering race is what broke this in the first place. POST /auth/verify
now names the address it confirmed, which matters when the browser holds a session
for a different account; the same reasoning as password_reset_required already
covers the disclosure.

Also here, from the 2026-09-02 review tail: the dead GET /auth/verify goes (both
senders emit the fragment form, and the last query-token link expired 24h after the
0.78.7 deploy), a spent #verify=/#reset= fragment is cleared while signed in, and
the auth-card banners get role=status. The verifyOkReset copy no longer blames
admin approval, which E9.5 S1 made false.
2026-09-03 23:45:31 +02:00
peter 243869401a fix(auth): stop discarding a legitimate password on admin approval (E9.5 S1)
SEC-10 revoked any password set while an account's email was unverified, on both
the Google-adoption and the admin-approval path. On the approval path that was
redundant: password_login refuses an unverified account before it ever reads
is_active, so approval hands a pre-emptor's password nothing it could use. All the
revoke achieved there was destroying the password a legitimate registrant had just
chosen -- and since the admin normally decides before the user reads their mail,
'your password was cleared for security' was the DEFAULT experience, not an edge
case. The guard stays on the Google-adoption path, where the real owner does attest
ownership.

password_reset_required and the ok_reset banner stay: accounts stripped on prod
before this change have no other way back in.

Two existing tests pinned the old rule, so they are rewritten rather than deleted,
and the SEC-10 recovery pack now builds the revoked state through the surviving
producer.
2026-09-03 23:32:34 +02:00
peter 3ac3d382e7 fix(auth): stop the address-bar mirror eating emailed auth tokens, and unlock revoked accounts
Two independent bugs made an email+password registration unrecoverable in prod.

The verification link did nothing. urlWithParams/clearParams rebuilt the URL as
pathname+query and dropped the fragment — but the one-time auth tokens ride the
fragment (#verify=/#reset=, SB3), and the providers that mirror nav params
(useUrlMirror in FeedFilters/Playlists/Plex/Channels) sit ABOVE the lazily-loaded
<App> in main.tsx. Their mount effect replaceState'd the token away before the auth
card's chunk had loaded, so the card read an empty hash: the link opened a bare
sign-in page, no request, no banner. Both helpers now carry the fragment over.

The account was then locked out for good. SEC-10 nulls password_hash when an
unverified account is attested (here: admin approval landing before the user could
verify — which the bug above made impossible). That is indistinguishable from a
Google-only account, and reset eligibility keyed off password_hash alone, so no
reset link was ever issued: no password to sign in with, and no way to get one.
users.password_revoked_at records the revocation, reset eligibility honours it, and
setting a password again (reset-confirm or set-password) clears it. An account that
never had a password stays ineligible on purpose — its owner adds one from Settings.

/auth/verify now also answers password_reset_required so the card can say why the
registered password stopped working, instead of leaving the user at the uniform
"Invalid email or password". Telling the holder of a valid verify token leaks
nothing: they have already proved they own the mailbox.

The 0078 migration backfills the stamp for rows carrying the exact lockout signature
(local, non-demo, no password, unverified), so existing victims recover unaided.

peter cb1f4f00b0 docs(auth): correct the last round of over-claiming comments and notes
Round 5's correctness/security pass came back clean; what was left was text that
said more than the code does.

- The register-path notify comment (and its test) claimed the admin "is still
  told". The call fires, but on a no-SMTP instance _send drops it — which is the
  open half of the problem, not something this branch fixed. Both now say so.
- The release notes tell admins what to actually do: an account whose address was
  whitelisted in advance has no pending request to approve, so the whitelist box
  is what activates it. That instruction only existed in the roadmap and in
  chores, which the dialog does not render.
- "That one line is the whole production change" now accounts for the test-only
  RateLimiter.reset() that also ships.
- The rate-limiter test claimed to pin that blocked attempts are not counted, on
  an assertion that held either way. Replaced with one that drives the clock
  across the window boundary and fails if hammering extends it.
2026-09-01 22:02:43 +02:00
peter f6e1d1e69f fix(auth): keep the admin notice unconditional on the register path
Round 4 showed the `inv is not None` gate added in b5a1002 removed a signal that
matters: for an address the admin had already approved, that email is their only
notice that someone has now created an account on it — the invite is not pending
so nothing lands in the Access-requests queue either. Suppressing it left the
registrant at "awaiting admin approval" with the admin unaware they existed. The
duplicate it avoided (Request access, then sign up) is mild noise by comparison.

The production change is now one db.commit(), which is all the reported bug ever
needed. Release notes corrected again: a previously-denied address was also
unaffected, the pending-request case never lost its queue entry (only the
account behind it), and the test inventory was missing a guard.
2026-09-01 21:48:40 +02:00
peter b64c3f514d fix(auth): drop the invite reopen — keep the fix to the lost account alone
Round 3 of the review killed the reopen from b5a1002: flipping an approved
invite back to pending let an unauthenticated POST /auth/register REVOKE a
standing approval for any whitelisted-but-unclaimed address, which then fails
is_allowed() and locks the real owner out of Google sign-in — the primary way
people get in here. It also re-armed the pre-emption window it was meant to
close, because with no SMTP email_verified is set True and the SEC-10 guard the
design leaned on never fires.

Two attempts at fixing the stranded-account UX in the same change both came back
worse than the wart. What remains is the narrow, real bug: the account was
silently rolled back and is now committed. An admin still binds the approval to
the account, exactly as before this branch. UX-25 in the roadmap records the
follow-up and both dead ends so they are not retried.

Also from round 3: the upsert docstring no longer claims the admin UI cannot
reach these accounts (re-entering the address in the same panel's whitelist box
does, and a test now pins it), the release notes are scoped to what the diff
actually changes with the operator note moved where the dialog renders it, and
RateLimiter has unit tests so reset() is not production code only a fixture
calls.
2026-09-01 21:34:38 +02:00
peter b5a1002412 fix(auth): reopen a pre-dated approval instead of auto-granting it
Replaces the activation added in ea931dc, which round 2 of the review showed was
a real weakening: on a no-SMTP instance it made a standing whitelist entry a
bearer grant — the first anonymous party to register an approved-but-unclaimed
address got an immediately usable account under that identity, with no
attestation, no admin action and no signal anywhere. The verify-time activation
had the same shape one step removed, and neither site ran the SEC-10 preset-
password guard or left an audit trail.

Keep a human in the loop instead. An approval granted before any account existed
was a decision about the ADDRESS, so registration reopens the invite
(upsert_pending_invite gains revive_approved, used only by the register worker).
The request lands in the Access-requests queue, approving it runs
_activate_user_by_email — and with it revoke_preset_password_if_unverified — and
the account activates. One mechanism, already audited, no new grant path, and
the "awaiting admin approval" copy is honest again.

The explicit commit from the previous commit still matters: with an invite
already pending, upsert returns without committing and _issue_token is gated on
SMTP, so a no-SMTP registration was still being rolled back.

Also from round 2: gate the admin notice on a fresh decision (matching the two
other upsert callers) so a retry no longer re-pings every admin, and reset the
module-level rate limiters between tests — the suite pooled every login into one
300s window and was two logins short of failing an unrelated test with a 429.
2026-09-01 21:18:14 +02:00
peter ea931dca30 fix(auth): honour an approval granted before sign-up instead of parking the account
Follow-up to the commit fix, from the deep-review. Persisting the account was
only half the story: when the admin had approved the address BEFORE the person
registered, the account landed is_active=False against an invite that is no
longer pending — absent from the Access-requests queue, and approve_invite 409s
on an already-decided invite. The sign-up worked and still could not sign in.

Derive activation from is_allowed() at the moment ownership is attested:
- verify_email_confirm activates a pre-approved account when the emailed link is
  confirmed (only the mailbox owner can follow it), so SEC-10 stays intact;
- _register_account activates only when there is no SMTP to verify with, where
  the admin whitelist is by design the sole gate — the same one add_invite
  already activates on.

Tests: the pre-approved no-SMTP case and the verify-activates case are real
regression tests (both fail without this change); guards cover the unknown-email
and denied->pending branches, verification of an unapproved account, and the
first end-to-end coverage of the /auth/register route and its
allow_registration gate. Release notes rewritten — the previous entry miscounted
its regression tests and advertised an email fix this release has no code for.
2026-09-01 20:56:43 +02:00
peter d954e71a77 fix(auth): commit the account on registration so a pre-approved sign-up isn't lost
_register_account() flushed the new User but relied on someone else to commit:
upsert_pending_invite() commits only when it actually writes an invite row, and
_issue_token() runs only when SMTP is enabled. For an email an admin had ALREADY
approved, on an instance where email is unavailable, neither fired — the session
closed and the account was rolled back. The would-be user got the uniform "ok"
and no account, could not sign in, and re-registering was a silent no-op.

Commit explicitly after the invite upsert (a no-op when upsert already committed
the same transaction). Three DB-lane regression tests cover the pre-approved
no-SMTP path (fails without the fix), the unknown-email path that always worked,
and the pre-approved path with SMTP on.

peter d37b6ef07f refactor(routes): delete 5 dead endpoints the frontend never calls (E3 S3, B-core-8)
None are referenced by the SPA or tests; the Scheduler dashboard's "run now"
covers every manual trigger. Removed: POST /api/sync/{rss,backfill,enrich}
(+ the now-dead _user_channels helper and three sync.runner imports),
POST /api/tags/recompute (+ its admin_user / run_autotag_all imports), and
GET /auth/me (a lesser duplicate of the canonical /api/me in routes/me.py).

This also retires a latent bug: POST /api/sync/backfill reset backfill_done /
backfill_cursor on already-fully-backfilled channels (tipping them back to
"needs full history") for up to 25 channels per curl. Full lane 365 pass.

request-access / demo / register / verify / verify-resend / password-login /
password-reset(request|confirm) / set-password each took an untyped `payload:
dict` and hand-picked fields with `.get(...)`. Replace with five small BaseModels
(EmailIn, EmailPasswordIn, TokenIn, TokenPasswordIn, SetPasswordIn) so FastAPI
validates the body shape and publishes the schema. Fields are `str | None` to
preserve exact behaviour — a missing/null field still coerces via the existing
`(... or "")`, no stricter 422s. Green under the auth-session suite (7), ruff clean.

peter 0340d0981c fix(e1): address /code-review high findings on the E1 stack
Review round on the whole E1 stack (main..HEAD). 6 findings, all low/medium,
none blocking; fixed for a clean gate-green handoff.

- plex/sync (correctness): the un-enriched cast guard compared the stored cast
  against THIS listing's length, so a trimmed Plex cast on a not-yet-enriched
  row was never applied. Compare against the listing CAP (_LISTING_CAST_CAP=20)
  instead: >cap = enriched (keep, survives a watermark reset), <=cap =
  listing-sourced (track edits in both directions). +2 regression tests.
- main (security): add X-Frame-Options: DENY as the legacy-browser fallback for
  the CSP frame-ancestors clickjacking guard.
- downloads/service (altitude): finalize_if_running now uses a SQLAlchemy 2.0
  update() construct instead of a hand-built text() UPDATE string — same atomic
  WHERE status='running', idiomatic, no identifier interpolation, no manual
  StrEnum coercion. Drops the now-unused text import.
- auth/admin (reuse): extract the SEC-10 "drop untrusted preset password + bump
  epoch" invariant into one helper (revoke_preset_password_if_unverified) so the
  Google-callback and admin-activation paths can't drift.
- tests/migrations (robustness): guarantee the shared schema is restored to head
  in a finally, so a downgrade/re-upgrade failure can't cascade into later tests.
- worker (simplification): align _finish_from_cache's display_name fill with the
  _download path's guard (no behavior change).

Gate green: ruff clean, 334 pytest (0 skip), frontend unchanged.

peter 18edbecb1e fix(auth): close the account pre-emption + wrong-account link holes (E1 S5, SEC-10/11)
SEC-10 (account pre-emption / "pre-hijack"): a password set on an account whose
email was never verified is untrusted — whoever registered the address (to
pre-empt the real owner) could have chosen it. Both the Google-adoption callback
and admin activation (_activate_user_by_email) now drop that pre-set password and
bump the session epoch when the account isn't email_verified, so a later Google
login / admin approval can't hand the pre-set password a working login. No-op for
a verified account (the legit no-SMTP flow). +2 tests.

SEC-11 (link/upgrade bound to the session default): the OAuth link/upgrade GETs
resolved to the session DEFAULT account, so a tab acting as a secondary account
would link Google / the YouTube grant to the wrong account. The frontend now
threads the active account through the navigation URL (withActiveAccount ->
?account=<active>), and _complete_link accepts any wallet account, not only the
default, so the identity lands on the account that started the flow.

Cleanup only, no behaviour change (ruff clean + pytest 193):
- keep the whole OAuth scope vocabulary together in app/auth.py: the bundles
  (BASE_SCOPES/READ_SCOPES/WRITE_SCOPES/_YOUTUBE_SCOPES) move back next to the
  atoms (READ_SCOPE/WRITE_SCOPE) as core; routes/auth.py imports the bundles it
  needs instead of rebuilding them from the atoms.

  limiters, the TTLs, the demo/scope constants) back into blocks.

peter 1b07d54663 refactor(auth): split app/auth.py — endpoints to app/routes/auth.py
R12 S2. app/auth.py (1154 lines) mixed the core auth surface with 18 HTTP
endpoints on one /auth router. Split by dependency graph:

- app/auth.py (223 lines) keeps ONLY the core surface other modules import
  (current_user, resolved_user_id, admin_user, require_*, has_*_scope,
  purge_user, count_admins, get_or_create_demo_user, google_enabled,
  is_allowed, operator_contact, optional_current_user) plus everything it
  transitively depends on.
- app/routes/auth.py (883 lines, new) gets the router + all 18 endpoints +
  their endpoint-only helpers, importing the core surface from app.auth.
- main.py includes auth_routes.router (was app.auth.router).
- test_oauth_redirect imports _oauth_redirect_uri from its new home.

The STAY/MOVE partition is driven by an AST scan of the COMPLETE external
surface (every `from app.auth import` incl. multiline + `from app import
auth; auth.X`), so no still-referenced symbol was moved. Behaviour-equivalent:
every symbol relocated verbatim (get_source_segment equality), route set
proven identical, no undefined names (symtable sweep).

Gate: ruff clean (backend + scripts), pytest 193 passed.
