bvandeusenandClaude Opus 5.5	7e6228c13f	docs: library comments say what the scanner and resolver do, not how they came to be (#6277) ... Rewrites the internal/library comment blocks to rule 32. Task, milestone, decision and rule ids are gone; the incidents behind them are restated as the constraint they left (why a file is deleted before its row, why the missing mark is a mark, why duplicates block on duration). Counts and album names from one library are dropped from production comments; test comments keep the names their fixtures use. The tagReadVersion log keeps each version's before and after, without the measurements. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-23 12:27:34 -04:00
bvandeusenandClaude Opus 5.5	f34423a0e0	feat: leveled FLAC stream for Sonos/UPnP speakers (M464 #5001) ... Speakers fetch their own audio, so the phone cannot level it. A cast token minted with level=true (and the client's asAlbum, which only the queue holder knows) now returns GET /api/tracks/{id}/leveled.flac: the track rendered by ffmpeg at the user's gain (volume=XdB, plus alimiter at -1 dBFS for a limiter-mode boost), metadata stripped, FLAC at 16 or 24 bits and at most 48 kHz. The gain is computed server-side from the user's preference and the stored loudness, carried as ?g=<centi-dB>&lim=0|1 and signed into the token, so an edited URL does not verify. Unity gains get the plain stream. Renders are written beside the cache file and renamed in, keyed by the source's size and mtime, coalesced per file (singleflight, detached from the requesting speaker so a retry finds the render running), started at mint time so the fetch finds them ready, and evicted least recently used past leveled_cache_mb, a new admin setting (migration 0068, Loudness analysis card).

bvandeusenandClaude Opus 5.5	f3196b3443	feat(library): measure every track's loudness in the background (M464 #4995) ... The first step of loudness normalization: the server measures each track with ffmpeg's EBU R128 filter (true peak, mono as dual mono) and stores the integrated loudness, true peak and loudness range in track_loudness (migration 0065). It also keeps a histogram of the 400 ms gating blocks at 0.1 LU, so album loudness can be computed exactly later with no second decode (#4996). The histogram reproduces ffmpeg's own figure (-10.68 against -10.7 on the captured fixture), and the analyzer logs a warning if the two ever drift. - A background worker, cloned from the fingerprint backfill, measures every track, new ones included. Measuring inline in the scan was dropped: the analysis decodes the whole file, and a large import could pass the scan's one-hour stuck threshold. The scan only deletes a changed file's measurement; the worker ticks every 10 minutes. - Timeouts, the cancel/missing-binary split and settled verdicts follow the fingerprint runner. Silence and undecodable files are stored as verdicts; stalls are retried. The deadline scales with track length. - loudness_settings (enabled, files at once) and an admin card with the coverage gauge, under GET/PUT /api/admin/library/loudness-settings and GET /api/admin/library/loudness.
