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.
VideoState, Playlist, PlaylistItem, SavedView, ComfortPin, Tag and ChannelTag leave app/models.py
for app/reader/models.py; app.tables registers them. No schema change.
Both Continue-watching rails built a show's card state inline; they now take it from rollup.show_state, so a show part watched with nothing to resume offers Play alone there too. A named reference counts only when its whole name is an HTML5 entity: html.unescape still decoded the legacy "¬" inside "¬ice;". Tests cover the grid's in-progress-but-not-resumable case through its SQL and both rails.
Show cards carry resumable (ShowState, from the same rollup) so a part-watched
show whose next episode is untouched offers Play, not a Continue and a Restart
that do the same thing; plexStarted is the one rule for cards and menus. The
Surprise rail's key sits under the discover root: whatever refreshes the rails
re-reads the draw (keep=) with its watch state now, kept past the 5-minute gc,
and only the reshuffle deals. Closing the player refreshes the Discover rails.
A show card's play acts on the last click only, and only where it was made.
The grid served Hungarian titles, but every other card surface (Discover rails, the
show page's episodes, search, collections, the person page, playlists, Home's resume
rail, hero and comfort shelf) served English. The card serializers now take a
required keyword-only lang (a forgotten call site fails instead of going English), and
each of those reads takes ?lang=hu, with the language in its query key. A Hungarian
search finds an episode by its Hungarian title too.
An episode on a poster rail showed its 16:9 still cropped into a poster, titled only
with the episode name; it now shows the show's poster and name, with S·E · title under
it (option A). Plex's generic season names (Season 1, Specials) are rebuilt from the
number in the reader's language; a season with a name of its own keeps it.
Home's comfort-shelf move wrote its optimistic order to the key without the language,
which nothing read any more; it writes the query's own key.
The comfort shelf resolved each pinned channel with three queries (the
row, its unwatched count, its newest video) and each playlist with two.
channels_summary gets the count and the newest row per channel as window
functions over one filtered set, playlists_summary reads every pinned list
in one query, and the rows come in one IN() each — so the shelf's cost no
longer grows with its length. A test counts the statements.
RAIL_LIMIT had two definitions held in step by a comment; the Plex Discover
route now imports the domain's. And rollup's "continue the latest-started
episode" was false: it takes the last in-progress one in broadcast order,
which is also what Home's next_episode picks.
The resume rail built its own SELECT instead of going through `filtered_query` and copied
only three of its predicates, so it dropped the per-user channel blocklist the module
docstring claims it inherits. Blocking a channel never touches `video_states`, so a
half-watched video from it kept its resume position and headed the rail — and, at the
default budget with the resume tier leading, became the landing page's hero: the app
answering "what should I watch" with the thing the user had just banned. The clause is now
`feedquery.not_blocked_cond`, shared with `filtered_query` rather than copied a second
time; the feed's SCOPE clauses stay deliberately unapplied, for the reason `yt_video_row`
already gives.
`next_position` returned the shelf's row COUNT while nothing ever renumbers positions —
`remove_pin` deletes, and every FK cascade removes a pin when its target disappears. Past
the first hole the count under-counts, so a new pin landed in the middle of the shelf and,
past the second, on a position another pin already held. `max(position) + 1`, the idiom
`routes/playlists` already uses.
`next_episode` took the FIRST in-progress episode in broadcast order while `plex.rollup`,
which drives the show page's Resume button, takes the last. One show therefore had two
different "continue watching" answers, with the Home tile ranking it by its most recent
touch and then offering the episode abandoned weeks earlier. The new test asserts the two
implementations against each other rather than against a literal.
All three mutation-checked: each new test goes red for the defect it names.
All three were measured before they were touched, and the diagnosis moved twice.
**Back from a Plex title played off Home landed on the Plex module's root.** One
click pushed three history entries: the page navigation, the sub-view opened by
the `jumpTo` hand-off, and — under StrictMode, whose effect body runs twice
before `setJumpTo(null)` re-renders — that same sub-view a second time. So the
first Back visibly did nothing and the second stranded the user on a Discover
page they had never visited.
A cross-module hand-off is the CONTINUATION of the navigation that brought you
there, not a second navigation, so it now REPLACES the page entry instead of
stacking on it (`useHistorySubview.open(view, {replace})`, asked for by the jump
target). Replacing is also idempotent, which is what disarms the StrictMode
double-run. The intent rides on `PlexJumpTarget` rather than being inferred,
because the header typeahead jumps from INSIDE the module, where the entry being
replaced would be a sub-view the user really was looking at.
**"Mást kérek" cycled nine cards and never left the resume tier.** Measured:
twelve presses, nine distinct titles, period nine, every one `tier: "resume"` —
the shelf and the surprise tier were unreachable by pressing the button. Two
causes multiplied: the tiers were tried in a fixed priority order over a 20-row
resume rail, so the button just walked down it; and the client's rolling
exclusion window of 8 guaranteed the wrap.
The press count now rotates which tier answers first (`start`), so each press
offers a different KIND of answer — the user's call, given the choice between
that, a wider window, and a surprise-only reroll. The fallthrough is kept, so a
press does not come back empty because the tier it led with had nothing. The
window is matched to the server's own cap rather than a smaller number of ours.
**A half-watched series on Home opened the show page.** A movie already went
straight to the player; only shows did not — and the comfort shelf and the hero
both resolved a show to its next episode while this rail alone did not, handing
back six seasons to choose between. The rail row now carries `next`, and the
client already played `next ?? card`, so this is a backend fix.
Affording it needed `queries.next_episode` to stop loading every episode of the
show into Python to pick one of them (236 rows for Friends, 227 for JAG) — three
ordered LIMIT 1 probes instead. The show→episode rule now lives in ONE function
(`rails.playable`), which is what the shelf, the hero and the rail all call; two
implementations are how they came to disagree.
Ten mutations run, all ten red for the right test — including a first pass where
the press count reached `api.discoverPick` and stopped there, invisible because
every Home test mocks that module. The slice now has its own URL test.
Verified in a clean browser tab against the live account: one Back returns to
Home, the rotation gives resume/comfort/surprise across nine presses with no
repeat, and Westworld opens at S1E1 rather than at its show page.
E24 S1. The anti-paralysis answer layer, served from our own Postgres with no
upstream call: one hero suggestion, one CROSS-SOURCE resume rail, and the user's
own comfort shelf.
Survey first, because the roadmap line was wrong about the starting point: Plex
already ships the whole trio (E5's Discover rails, including a reshuffling
Surprise me), the YouTube side ships none of it, and nothing anywhere answers
the question across both. The data already existed on both sides — VideoState
and PlexState are structurally identical, the feed has an `in_progress` filter
and a seeded shuffle, and the YT player already resumes position.
- app/discover/budget.py — the time bands. "How much time do you have"
(10 perc / 30 perc / egy este / mindegy) replaces 15/D's mood questionnaire:
deterministic, answerable from a column we have, and it picks the source for
free. Matched against REMAINING time, so a film with 8 minutes left is a
ten-minute answer. An unknown runtime fits only the unbounded band.
- app/discover/cards.py — a thin unified card that carries the NATIVE feed /
Plex payload, so the page renders with the existing card components instead of
a third one. `aspect` is the one new field: a rail needs to know poster from
16:9, and that is a property of the artwork, not of the module.
- app/discover/queries.py — the SQL, reusing feedquery and plex.rollup rather
than the Plex Discover ROUTE, whose LibraryFilters narrowing belongs to a
surface that has a sidebar. One seed drives both halves so a reroll moves
them together.
- app/discover/hero.py — resume -> comfort -> surprise, with the chosen tier in
the payload so the client labels it honestly instead of guessing.
- comfort_pins (0083): five nullable CASCADE-ing FKs under num_nonnulls(...) = 1
rather than a flag or a polymorphic string ref. A flag cannot order a shelf or
hold a channel; a string ref would let a deleted library item leave a dead tile
on the one surface whose whole job is to be reliable.
Two honest-state rules the tests pin: the surprise draw excludes anything
already started (the resume tier may have skipped it for not fitting, and
offering it back as "Meglepetés" would contradict the question), and which
source leads the draw follows the seed, so the Plex library can actually answer
"egy este".
