- tracks carry a stream_url signed for the user for 12 h and the user's reaction; /stream checks the signature, expiry and that the user is not blocked, then hands the file to nginx by X-Accel-Redirect (or serves it with Range support when X_ACCEL=false) - original by default; formats browsers can't play and explicit high/medium/low go through Opus transcoding, never upwards: a lossy source under the target bitrate stays original; transcodes are cached per file and size, deduplicated in flight, limited by TRANSCODE_CONCURRENCY and trimmed hourly by LRU to the size limit - /events takes up to 500 events with client UUIDs, drops repeats and events older than 30 days, counts plays (≥ half or 4 min, or finished), early skips and history entries (≥ 30 s) - history with clearing, likes and dislikes with cursors and totals, track reactions, playback state with last-write-wins, tracks batch Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
