- Guard episode deletion against double-submit with an isDeletingRef +
setIsDeleting pair threaded through buildDeleteEpisodeHandler, and
disable the MediaHeader delete button while a request is in flight.
- Restore MediaHeader title truncation by adding min-w-0 flex-1 to the
h2 so long titles shrink instead of pushing the delete button away.
- Normalize the headword in FrequencyRankTable before comparing it to
the (hiragana-normalized) reading so katakana-only entries like カレー
no longer render a redundant 【かれー】. Test strengthened to reject
any bracketed reading, not just the literal.
- Rewrite confirmBucketDelete copy to include the "and all associated
data" warning and handle singular/plural cleanly.
- Run Prettier across the stats files CI was complaining about
(EpisodeDetail, WatchTimeChart, SessionsTab + test, FrequencyRankTable
+ test, session-grouping test) to clear the format:check:stats gate.
Group sessions for the same video inside each day header so repeated
viewings of an episode collapse into a single expandable bucket with
aggregate active time and card counts. Multi-session buckets get a
dedicated delete action that wipes every session in the group via the
bulk delete endpoint; singleton buckets continue to render the existing
SessionRow flow unchanged.
Delete confirmation copy lives in delete-confirm for parity with the
other bulk-delete flows, and the bucket delete path is extracted into a
pure buildBucketDeleteHandler factory so it can be unit-tested without
rendering the tab. MediaSessionList is intentionally untouched -- it is
already scoped to a single video and doesn't need rollup.
