Music Library

Multidimensional music library catalog built WITHOUT touching the filesystem: the inventory and raw tags come from an existing gonic scan index (gonic.db, read over SSH with sqlite3 -json -readonly), so no array disk is ever woken by a directory traversal.

On top of the raw rows the scan method builds a star-schema cube:

• facts — one album resource per album directory (album → disc → track nesting, disc subdirs like CD1/ collapsed into their parent album)
• dimensions — one artist resource per artist (name variants, album refs, genre/format/year span) plus rollup dimension resources for genres, years/decades, formats, and quality buckets (lossless / lossy-high / lossy-mid / lossy-low)
• cross-cuts — an issues resource (untagged tracks, dirname-only albums, encoding fixes with before/after, DOS-mangled 8.3 names) and a library summary with totals and source breakdown

Every tag string passes through encoding recovery: legacy single-byte tags decoded as latin1 (cp1251 / koi8-r / cp866 / windows-125x / CJK mojibake such as "Êëàóäèî Ìîíòåâåðäè") are detected with jschardet and re-decoded; double-encoded UTF-8 is unwrapped. Tracks with missing tags fall back to directory/filename naming patterns ("1983. Artist - Album", "Artist - Album (Year) [FLAC]", "NN - Title", disc subdirs, bracketed artists, catalog-number prefixes).

The probe method deep-probes one file with ffprobe inside a docker container that has the music share mounted (all formats ffmpeg knows: mp3, flac, opus, m4a, ogg, ape, wma, wav, …), merging format-level and stream-level tags and reporting the encoding-fix trace — for debugging individual files.

Release 2026.07.16.2 — align model versions with manifests

Maintenance release across the @magistr extensions. For most packages this carries no functional change: the only edit is the model's version: field, brought back in line with its manifest version so the published model type version and the package version no longer drift.

Functional changes in this release are limited to:

• anime-cron: normalizeTitle now strips a ": subtitle" suffix and a trailing parenthesized year before comparison, fixing dedup false-misses where the torrent title carries a subtitle or year that the AniList romaji does not.

• arckit: first publish. Standalone ArcKit port — a 12-phase architecture governance state machine with 65 bundled templates, driven by a bundled skill.

Also tracks three extensions (kaiten, observability-agent, music-library) that previously existed only as untracked working-tree directories, recovered from stashes.
