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.
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".
