A formatted value took the reader's language even when the notice was said in English for the
log. The platform-namespace contract matched only t("…"), so a domain key passed through msg()
in components/ui/ went unseen. Three comments pointed at localizeDetail's old home.
The rollback after the conflict puts the old name back on the row, so the refusal read
"you already have a view named 'hh'" when the taken name was 'gaming'.
The 10 s tick in flight when the player finishes (or a refusal rollback whose state write in fact
committed) wrote its mid-item position onto the freshly watched row and scheduled a resume push
after the scrobble, so Plex showed the item in progress again. The checkpoint is now a conditional
write that skips a row marked watched in the last 30 s and answers like a finish; a rewatch past
that is checkpointed as before. Marking an item (or a season/show) watched also supersedes resume
pushes still in flight, as the near-end finish already did.
The artifact guard parsed the sequence with int(), so a zero-padded or non-ASCII-digit name read
as a segment the session had reached and parked the sync route for the full 20 s wait. It now
also requires the canonical spelling segment_name() produces.
Stopping, replacing, culling or reaping a session waited up to 3 s for ffmpeg and deleted a whole
segmented film under _lock, which every segment request and checkpoint takes. Teardown now signals
the process and moves its directory aside under the lock, and waits/deletes after it. A new session
on the same path still waits for the dying ffmpeg first (it writes by path), and the orphan sweep
recognises a moved-aside directory left by a crash.
The player names what it plays in its own history entry (watch, wrel, wtab): a reload or a
bookmark reopens it on the page that hosts it, with that page's list as the queue, or alone
from the catalog (GET /api/videos/{id}/row); a page that hosts none gets the shell's. Back
lands on the page's address without it (useBackToClose's url; ui/Modal passes it on). The
Files viewer and player do the same (fview, fplay). The Plex and channel-manager views are
always written in full, as their fallback is remembered state.
pg_locks is the whole server's: under the parallel lane a worker's own advisory claim on the same playlist id, or its own lock wait, was counted by another worker's probe (a leak reported where there was none, a commit made before the second tab blocked).
The slot was kept as soon as search.list was about to be called, so a search refused before it went out (no connection, no token) cost the user a slot for nothing. It is kept now only once the client recorded the call's units, or the request went out and its answer never came (YouTube may have counted it): YouTubeError says whether a transport failure was sent, and the client counts what it spent.
The process lock around the budget check and the call is waited for at most ten seconds; past that the search is refused as busy (search_busy, a retry can help) and gets its slot back, instead of parking a request worker behind every slow call before it. The lock test now pins one hold around both steps, and the busy test fails on a wait without a bound.
An API-sourced live search that reached search.list has spent 100 units (the client records them
before it reads the status), so it keeps its daily slot: refunding it let a bogus cursor spend the
shared budget without ever counting against the cap. A failure before the call still gives the slot
back.
Every refund is rationed too (5 an hour per user and list): a cursor is a free string, and a request
built to fail would otherwise scrape YouTube from the server without end.
The API source asks the budget again right before search.list, under one process lock with the
call: checked apart, searches sent together at the last 100 units all passed and all spent.
Checked first and logged after search.list, requests sent together at the
last free slot all passed, and each spent 100 units of the shared budget.
Every live search now claims its slot (quota.claim_action) whatever the
source, and gives it back when it showed nothing. The cap counts the
zero-unit claims only, so search.list's own spend event is accounting,
not a second slot. log_action, the unlocked writer, goes.
Tests: the API source reads one page per request, is refused before the
call when the budget cannot pay, counts one slot per search and refunds a
failed one; the lock test now proves the count happens after the lock.
The watch frame alone read as "nothing related" — so a related column YouTube moved, or a list
drawn by renderers this does not read, answered an empty list instead of an error. Now only the
"isn't available" promo YouTube draws for a video it no longer has is an empty page; anything else
it cannot read is a ScrapeError.
The flattening of a video renderer and the read of the continuation token are one each, in
innertube, for the search and the related scrape.
A related list's cursor cost nothing, and a cursor is a free string: a replayed one read and
enriched without end. Every request now takes a slot of the user's daily cap — taken under a lock
before the work (`quota.claim_action`), so requests sent together cannot all pass the last free
one, and given back when the request fails outright (`quota.refund_action`). The live search's
scrape source takes its slots the same way.
A limit of 0 turns the feature off: a distinct 409 `related_disabled` / `search_disabled`, and
`/api/me` says `related_enabled` / `search_enabled` so the UI can leave it out.
A videos.list that fails no longer reads as an empty page: `ingest_candidates` raises, and the
search and the related list answer the refusal (the shared budget spent says "quota") instead of
"no results". The two routes' page loops are one (`_gather`).
`clear` deletes only what the caller found: a related list's rows carry no find, and any user
could name them.
The player shows what YouTube lists beside the video, without what the
user has watched or hidden. Wide, a Related tab beside the description;
stacked, a button beside the info opens them in a drawer. A row plays in
the same player (Back returns) and the list stays the opened video's.
A switch picks on-topic or Hungarian-trending lists, kept on the account.
Each related row says whether the user follows its channel; the row is
the video card's narrow form with its whole menu. VideoMenu moves to
features/video, where the player can reach it.
GET /api/search/related/{video_id} reads the list YouTube shows beside a
video from the website's InnerTube "next" endpoint (no quota), and brings
it into the catalog the way live-search results come in. It leaves out
what the user watched or hid, here or in their Takeout history (unless
taken back to "new" since), blocked channels and the video itself, and
pages on until 20 are gathered (at most 4 pages). region=topical|hu picks
the locale the list is filled in. Its own per-user daily cap
(related_daily_limit_per_user, one event per opened list); a failed
scrape answers 422 youtube/unavailable.
The InnerTube request (live key, consent cookie, errors) moves into
youtube/innertube.py, shared by the search scrape and the related one.
A subscription pulled in from YouTube left an explored channel flagged as an exploration's, so its
later videos came in hidden from the Library with their watched marks waiting for good; a subscribe
landing while an exploration's videos came in left those flagged too. One step, settle_explored,
now holds the rule by who follows the channel now: the subscribe here, the subscription import, the
watched-channel videos and the explore page all end with it. Migration 0116 clears what the gap
left behind.
The list's "may still grow" count no longer counts a channel it already shows from a stub row, and
the comments on the cleanup's keep rule and on the in-memory daily shares say what they do.
- A channel someone follows: the videos its exploration brings in (the list's
dialog, the channel page's explore) come in as the catalog's own, not
flagged via_explore, which subscribing would never clear and which kept
their watched marks waiting for good.
- The explore cleanup keeps the row of a channel a Takeout history shows
watched (it still reclaims the videos), so a looked-at channel no longer
drops off the list.
- The Shorts job takes up only users whose list still has lengths to ask or
channels to name, by each user's own follows, blocks and dismissals; a
naming that failed is tried again, and the list says it is not complete.
- The length lookups have a daily share of their own: a large history no
longer leaves the export's Watch later file waiting a day.
- Only a channel of the user's own history can be put out of the list.
- The dialog's videos have a query root of their own: the list's
invalidations no longer re-ask (and re-explore) under an open dialog.
The import asks YouTube how long the watched videos of the candidate
channels are (five or more watched, none the user follows, blocked, put
out or owns), keeps the length on the Takeout row and names the channels
that make the list: five videos of five minutes or more. The shorts job
asks what an import could not. A channel's counted videos come in as an
exploration's when its list is opened, ready to play; a channel can be put
out of the list and back.
- An ad-hoc request made while its target's run is under way is the run after it: the scheduler
dropped a second fire of a running id, so a second Takeout file was never imported and its key
stayed queued until a restart.
- Un-marking or resetting a video is remembered (video_unmarks): an import of an older YouTube view
no longer marks it watched again; un-marks take the user's Takeout lock.
- One user's failure in the Shorts job's Takeout pass is theirs: the job keeps its own result, the
others are settled, and a failed lookup spends none of the daily share.
- The upload reads the user's id before giving the read connection back.
- A watched row waits on a discovery video (search or explore) until the catalog keeps it, so a
mark never pins it against the cleanup jobs.
- The history is decoded a window at a time, a Watch later file over 2 MiB is refused unread, and
two uploads at once across all users (takeout_server_busy).
- A Watch later list goes in as one presence read and one insert.
- Uploads: one at a time per user and ten an hour, each refused only after its body arrived;
the history read an entry at a time (32 MiB cap), a Watch later list capped at YouTube's 5000,
a user's kept videos at 200k; any unreadable shape is a 422, not a 500.
- Quota: Watch later lookups stop at the backfill reserve and at a per-user daily share; what is
not asked about waits, known videos still go in, and the shorts job retries the rest.
- Staging and settling share one per-user advisory lock (no deadlock); a run settles only the
rows it read, so a row staged meanwhile is never called gone.
- A failed run's notice names a translated failure, never the upstream's text.
- The status says when an import is queued; the page watches it to its end even when left, then
reads the feed, its counts and the playlists again.
- Settings: one live region, the zone kept (unavailable) while a run goes, focus handed back,
a missed drop kept from the browser, an oversize file refused before it is sent.
- Scheduler and run lists show Takeout runs by the importing user.
A watched video the catalog did not know at import time waits in `takeout_items`. The Shorts job now
settles those rows right after its probe (the only place a video's Short-ness becomes known), every
user's, a commit each: `reader.takeout.apply_waiting`, its count in the job's result.
`GET /api/takeout` is what the settings page reads: the user's last import run (`jobruns.last_run`)
and the kept videos by kind and outcome, "waiting" for one not known yet.
The YouTube API reads neither a user's watch history nor their Watch later list, so the Takeout
export is the only way in. `POST /api/takeout` takes one file of it (watch-history.json or
Watch later-videos.csv, told apart by content), keeps its videos in `takeout_items` and queues the
user's `takeout_import` run, whose outcome reaches their inbox.
The run marks watched the known videos the Shorts probe has cleared, at the Takeout time; a Short
is not marked, and a state the user set here (watched, hidden, or changed after that time) wins, by
the upsert's own condition. A video the catalog does not know yet waits with no outcome. Watch later
videos are fetched if unknown and appended oldest first.
An ad-hoc run can now ask for a completion notice (`run_ad_hoc(..., notify=True)`).
- /auth/google/connect is a navigation and carries no headers: the tab names the account it
was built for in `expect`, checked by the same comparison as the request header
(built_for_another_account); a mismatch lands on /?account=changed
- the link marker names the OAuth state of its own flow: an older flow coming back no longer
spends the marker of the connect still open (which then returned as a plain sign-in)
- a 401 account_changed reloads the tab with a one-time flag, and the reloaded tab says it
now shows the account signed in
- a refused switch to a suspended or not-yet-approved account says so in the signed-in
app's words, naming the address a request was recorded for
- the prefs merge locks FOR NO KEY UPDATE, so a transaction that only added a row referring
to the account does not hold the save up; a test pins the lock
- giving up a lost page closes a channel page open over it
- e2e README names the chromium-only specs
A tab names the account it was claimed for on every request, beacon and upload
(X-Siftlode-Expect-Account); current_user and /auth/logout refuse a mismatch with
401 account_changed and keep the session, so a tab left showing the account
signed in before reloads instead of writing to the new one.
/auth/login clears a connect marker left by an abandoned connect, and a link
completes only on a session that still holds. The prefs merge reads the row
under a lock. A tab's sessionStorage records its own owner. A page the account
loses is given up, address bar and remembered page included. The panel layouts
are preferences; the storage contract also refuses a key handed to the Storage
API or to usePref outside its kind. A refused sign-in as someone else and a
failed sign-out say so. The chromium-only e2e specs are in the gate register,
the member walk waits for its requests, and devices.spec checks the save itself.
/auth/link and /auth/upgrade become /auth/google/connect?access=identity|read|write: one handler, one
table of what each access asks Google for, the same callback markers. An unknown access is refused
(422) instead of quietly meaning read, and an instance without Google answers ?link=error for a
grant too, not a silent return to the app. The frontend builds the URL in lib/googleConnect, and a
contract test holds it to the backend route and its access values.
The session held a wallet of up to six accounts, and a request picked one by a header or an
?account= parameter. It now holds one: user_id and its epoch. A sign-in replaces whoever was
signed in, sign-out and account deletion end the session, and an account refused mid-session
(revoked, suspended, deactivated) clears it. /api/me/accounts and /api/me/switch are gone, and
with them their refusal codes and the UI copy for them.
A cookie the multi-account build wrote carries no single epoch and is refused: its holder signs
in once more. A Google link finishing in a browser now signed in as someone else is refused, as
before for an account outside the wallet. A test holds that no app code reads the wallet keys or
the account header again.
The test's own writes are committed before a request, so a handler's Core DML can no longer hide
in a transaction the test had already opened. The entry-point probe answers on a marked line the
API's logging cannot mix into. A listed commit whose function no longer commits fails the fence.
CLAUDE.md and the backend README now name what an AST cannot see; the route-commit tests no longer
claim their read-back holds the commit.
A season marked watched, a pull from Plex and a YouTube resume point made their first row by a read
then an add, and failed on the unique key when a first checkpoint or the watched mark made it in
between. They go through the same insert-then-read as the checkpoint (the resume point is one
upsert); a pull that meets a local change still waiting for its push leaves it.
Folding duplicate Watch later lists moved their videos but not a Home pin, which the cascade then
deleted; the first pin of a dropped copy moves onto the kept list.
Marking one notice read trimmed before its own flag was flushed, so the trim left one past the cap.
The route test now crosses the cap and reads the result from a session of its own.
Each handler that now calls a service and commits is driven through HTTP once.
A second account's watch state, Watch later list and private download profile
are never read or changed. The autotag job's orphan prune is seen committed.
The first checkpoint of an item and the final flush beside it both read no
state and both inserted; the loser failed on uq_plex_user_item. Two first saves
each made a Watch later list. Both are created by an ON CONFLICT DO NOTHING
insert and then read; a partial unique index holds one Watch later per user, and
the migration folds an existing second list into the first. Plex keeps one
per-item state map (rollup.item_state_map).
The owner-filter check missed an aliased() model, an import alias, .in_() and
filter_by; four live inline filters on aliased VideoState go through owned_by now.
Cross-unit writes are seen under any import name, through sa.update and via
__table__. Core modules may commit only where CORE_COMMITS names the reason;
trim_read and audit.gc flush now and their callers commit. The pin target, the
debug-session header and a link's target fetch through owned_row. The docs
claim what the fence holds, and say what is beyond it.
A db.execute(update/delete) fires no flush and stages nothing, so a handler whose
only write was Core DML could forget its commit and stay green. The check now
asks Postgres whether the request opened a writing transaction. It found one
real case: a repeated issue send returned with the session row still locked.
The models now live in their units' packages, and a core model names a unit's by
string (User.subscriptions -> Subscription). The download child imports neither
catalog nor app.tables before db.get, so mapper configuration failed and every
download, clip, edit and upload job died with child_exit. Each entry point now
imports app.tables, and a test imports each one in a clean interpreter.
The per-file pin list and the unit-by-unit switch go: every route file is held
to zero database work, every unit's package to its edges, and core code says
whose a row is through userscope too. CLAUDE.md, the backend README and the
gate register describe the units as they now are.
Tokens, notifications, quota, debug sessions and the reset-link burn filtered
their owner inline. Ten of the fifteen filters had no test that noticed one
going missing; each now has a test where another account's rows must not
count, show or change.
The last Plex HTTP files do no database work of their own, so ALLOWED is empty: no route builds
SQL, touches the session or a unit's table. Discover's rails move whole into plex/discover.py; a
user's playlists, watch-state writes (the race-safe finish, an early checkpoint, a status, a
season or show at once) and the watch-sync link go through plex/queries.py and plex/service.py.
The plex package joins FENCED: it reads no other unit's tables, says whose a row is through
userscope (the rollup and the watch sync's 8 inline filters moved to owned_by), and commits only in
its named jobs — the library sync, TMDB enrichment, the watch sync and its background pushes.
A playlist's has-item probe keeps the plain key lookup, so a NUL in it is still the 422 a test pins.
Pins 178 -> 0; basedpyright baseline 118 -> 106.
The HTTP files browse, detail, people, collections and _shared do no database work of their own
now. New plex/queries.py (the rows a page shows, a user's watch state through userscope),
plex/service.py (the info pages' enrichment, a collection's editable flag, the row kept after a
failed follow-up read, the person bio's background fetch; none commits), plex/library.py (the
unified browse feed, its search and facets) and plex/collections.py (a collection's source,
editability, card, certificate and member order). Every watch-state join in the moved code names
its owner through owned_by.
Pins 354 -> 178 in 4 files; basedpyright baseline 132 -> 118.
PlexLibrary, PlexShow, PlexSeason, PlexItem, PlexPerson, PlexCollection, PlexState, PlexLink,
PlexPlaylist and PlexPlaylistItem leave app/models.py for app/plex/models.py; app.tables registers
them. Every import is re-pointed; no schema change.
Channels, search and sync do no database work in their routes any more: reads go through
catalog/queries, writes through catalog/service, and a live search's ingest is catalog/search.
What a catalog route needs from Reader (a playlist's channels, a user's tag links, the feed
projection of results) it asks reader/queries and reader/service. The scheduler and the runs page
read channel titles and the work queue through catalog/queries. Catalog is fenced below its HTTP
layer: its owner filters go through userscope, it reads no other unit's tables, and its ingest
jobs commit only where they are named.
Channel, Subscription, Video, SearchFind, ExploredChannel and BlockedChannel (and LIVE_OR_UPCOMING)
leave app/models.py for app/catalog/models.py; app.tables registers them. The User↔Subscription
relationship names its other side as a type only. No schema change.
A reorder's left-out item, a playlisted video beside one not asked about, another user's tag, and
the user's own channel link committed before the auto-tagger reads the table.
Feed, playlists, saved views, tags and the Home pins do no database work in their routes any more:
reads go through reader/queries (and feedquery for a feed page, its counts and facets), writes
through reader/service and discover/pins, which flush; the handlers commit. Reader is fenced below
its HTTP layer too: its owner filters go through userscope, and the catalog's jobs ask Reader
instead of joining its tables (the auto-tagger's system tags, the cleanup jobs' keep rule, the
maintenance notice). A playlist sync's catalog ingest moves to sync/videos.
