Speed becomes a per-USER-per-BOOK preference that syncs across
devices, with a user-level default for books not yet played:
- new audio_playback_speed table (mirrors reading_speed's shape; a
preference, NOT a measurement and NOT a reading_progress column) +
users.default_audio_speed, schema in place
- chapters endpoint resolves per-book row → user default → 1.0 and
ships playback_speed + default_playback_speed (zero extra round
trips; default powers the dropdown marker)
- PUT /api/media-items/:id/audio-speed upserts (range-checked; the
client SPEEDS list stays the real gate; library visibility gates
writes)
- the user default rides the profile path like theme/timezone:
profile form gains a 'Default Playback Speed' select (server-side
SpeedOptions mirrors the web SPEEDS list), GET /profile carries it
- web: restorePosition applies the resolved server speed (localStorage
audio_speed demotes to a first-paint cache); setSpeed PUTs
fire-and-forget with a failure toast; the Speed dropdown gains a
'(default)' row marker and a 'Make N× my default' action with a
success toast
ALSO fixes a pre-existing profile-page bug surfaced by the §8 form
verification: the password section's current_password input was
required INSIDE the shared form, so HTML5 validation blocked every
Save Changes submission (dead since the shell migration). The
password flow keeps its own gates (disabled-button checkers + server
400).
Integration test TestAudioPlaybackSpeed pins the full contract (unset
→ 1x, upsert resolution, range rejection, default fallback for
row-less books, default updates re-satisfying unset books). Verified
live: 9 Playwright checks.
