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.
