Deep-review R5 — five defects in the Remove button f76a2afb put inside the YT player:
- It removed from whichever playlist was selected by the time it was pressed, not the one the player
was launched from; the selection can change under an open player (the command palette opens over
it). The launch list is now part of the player snapshot, and the optimistic row removal only
touches the list actually on screen.
- A 403/404 failed in total silence: the catch claimed the global dialog had reported it, but `req`
deliberately leaves those to the caller. It now notifies, as moveItemTo already did (the silent
catch predates this round; the full-screen consumer did not). New key playlists.removeFailed, HU+EN.
- It computed the next item from the cursor as it was when the button was pressed, but prev/next and
auto-advance keep working under the confirm dialog: the viewer was thrown back onto a video they had
moved past. It reads the live cursor, and if they moved on it just drops the item from the queue.
- The button was disabled for the confirm's lifetime, so the dialog's focus restore hit a disabled
element and a keyboard user who cancelled was left on <body>, outside the aria-modal player. A ref
guards the double press instead.
- Its accessible name was a bare "Remove"; it now names its object, like the row control.
The call-site wiring (step on, drop from the queue, close on the last item, leave everything alone
when the removal did not happen) finally has tests. Verified on localdev in the real YT player: a row
reopened at the 136 s it had just stored; Cancel returned focus to the Remove button; a confirmed
removal stepped 1/3 -> 1/2. 10 mutations, each red on its assertion. Scratch list and positions reset.
Deep-review R4. 1630a3df wrote the YT player's stored position into the react-query cache so a
reopen could not rewind it — but only the feed actually read it back:
- Playlists renders from its own undoable copy of the list, re-seeded only when the SET of ids
changes, so the patched position never reached it: close a video at 830 s, reopen it from the
playlist, and it resumed at the old spot and the next checkpoint wrote that over the 830. A detail
with the same membership now rebases its fresh rows into every snapshot, keeping order and undo
history. (The ids-only guard is older than this round; the write that depended on it was new.)
- Live YouTube search results carry the same per-user position and open the same player, but their
cache was never patched. It is now — patched only, never invalidated, since refetching an
API-sourced search page spends 100 quota units.
Tests for what had none: a Playlists harness (PlayerModal stubbed to record its launch props) and a
PlayerModal harness with a fake IFrame API that records where each item is started — the latter pins
that stepping back to an item watched earlier in the same session resumes at THIS session's position.
3 mutations, each red on its assertion.
