A background Fingerprinter runs after every scan and at startup, one file
at a time, filling media_files.sha256 and track_fingerprints (fpcalc raw,
first 120 s). Without fpcalc only SHA-256 is computed and files stay
queued for Chromaprint. Changing a file's content resets its prints.
Similarity() compares raw prints with a ±80-point alignment search; it is
the basis for duplicate detection in the upload queue.

- /wave/options, POST /wave/sessions (activity, mood, seed),
/next with reactions, PATCH to switch the context on the fly, DELETE
- the recommender is called with an 800 ms budget; on failure the api
serves a fallback wave of likes, favourite artists and random
available tracks with the same dislike / recent / served filters
- every served track is an impression with its source and model; wave
events (context_type wave) set its outcome, reactions win
- library status shows the analysis queue and 7-day wave metrics:
listen-through, early skip and like rate

- covers are taken from the embedded picture of the first track or a
cover/folder/front image in the album folder, converted by ffmpeg to
WebP 64/300/1200 and named by content hash, so albums sharing a cover
share the files; a full scan looks again for albums without one
- a 3-colour palette (dominant, second, most saturated accent) from a
deterministic k-means feeds placeholders, page tints and the wave
- /covers/{id} is public but HMAC-signed and immutable; nginx serves
the file via X-Accel-Redirect, X_ACCEL=false serves it from api
- the web client picks the size by display size and pixel density
- install.sh and update.sh generate STREAM_SIGNING_KEY

- schema for sources, path patterns, media files, artists, albums,
tracks, genres (migration 00003)
- path patterns (RE2 with named groups, skip), merge with tags by
source priority, fallbacks from the file name and folder, name
normalization and multi-artist split
- scanner: walk, skip unchanged files by size and mtime, ffprobe in 8
workers with a single catalog writer, renames by content hash keep
the track, duplicates fold into one track with the best file as
primary, missing files are kept 30 days
- storage-agent mounts NFS with validated server, export and an option
whitelist, no shell; test mount counts audio files
- admin API: sources CRUD, connection test, patterns with preview,
scan, library status, file errors, host folder picker; scheduled
scans and health checks; mounts are restored on start
- catalog API: artist, artist albums, album with tracks, track
- api image is alpine with ffmpeg for ffprobe
