listening_history was populated ONLY from the media server; the web player
recorded nothing. Now a play heard ~10s logs to listening_history AND bumps
tracks.play_count/last_played — so the existing 'recently played' query reflects
actual SoulSync listening, and the Phase-2 smart-radio recency signal gets real
data.
- core/playback/play_log.build_play_event(): pure, DB-agnostic normalizer from
player payload -> listening_history event shape. Caller supplies the
timestamp (stays pure). Composite/streamed ids never become the int
db_track_id; bool ids rejected; missing title -> skip. 9 unit tests.
- MusicDatabase.record_web_player_play(): inserts the history row + increments
play_count/last_played for the library track in one call.
- /api/library/log-play: thin endpoint, server-side timestamp, best-effort
(logging failure never 500s / never affects playback).
- Frontend: npMaybeLogPlay on timeupdate fires once per track at the 10s
threshold (flag reset in setTrackInfo, set-before-fetch so it can't
double-fire), fully fire-and-forget.
Pure builder is unit-tested; the DB write can't run in-sandbox (real DB throws)
so it's a thin straightforward insert+update. JS + web_server parse clean.
