Task 1 checkpoint:decision resolved by operator: hybrid-identity (path
row key, lazily-backfilled content-hash dedupe column), derived-albums
(computed at read time from track tags, not stored rows), a single
JSON index at data_dir/music/index.json matching content_server.rs's
load_catalog precedent, and both own-library + peer sources indexed.
MUSIC_SCHEMA_VERSION starts at 1; a newer-version index on an older
binary is treated as absent rather than reinterpreted or overwritten.
