* refactor(model): extract canonical 128-bit base62 id codec
* feat(model): generate random ids as canonical 128-bit base62 values
* feat(scanner): emit legacy PIDs in canonical base62 encoding
* feat(db): add id canonicalization transform for the uniform-ids migration
* feat(db): migrate all ids to canonical 128-bit base62 encoding
* fix(db): canonicalize ids in junction tables and JSON columns
* chore(jellyfin): update id-family notes for uniform canonical ids
* test(ids): harden codec input contract and migration edge coverage
* refactor(model): use log.Fatal for Encode128 contract guard per project convention
* fix(db): force full rescan after id migration for legacy PID configs
* test(db): guard id-column inventory against schema drift
* refactor(ids): compile-time Encode128 contract and unified column rewrite helper
* refactor(db): apply review feedback to id migration
Filter empty strings in collectColumn's SQL, reuse a prepared statement
for rewriteColumn updates, and clarify the legacy ID functions' comment
now that they emit the canonical encoding.
* feat(auth): split session and public-link JWT secrets, rotating sessions on id migration
* test(subsonic): initialize public token secret in helpers suite
The suite sets auth.TokenAuth directly instead of calling auth.Init, so the
new PublicTokenAuth was nil whenever Ginkgo's spec order ran a helpers spec
before any spec that calls auth.Init, panicking in publicurl.ImageURL.
* refactor(db): inline canonicalID into its only consumer, the uniform-ids migration
* refactor(model): rename Encode128/Decode128 to Encode/Decode
With every id now exactly 128 bits, the width suffix is redundant; the
package-qualified id.Encode/id.Decode carries the same information.
* test(db): make the id-columns guard classify JSON columns too
The guard only inspected columns named id/pid/*_id, so it could not see ids
embedded in JSON. Widen it to *_ids and to every JSON column, and drive the
"covered" set from a new embeddedIDColumns list instead of the inline calls
in the migration.
Every JSON column the schema has now carries a verdict. The four denormalized
caches -- media_file/album.participants, media_file/album.tags,
album.folder_ids and artist.similar_artists -- hold only artist, tag and
folder ids. Those all come from id.NewHash, whose 22-char base62 encoding of
a 128-bit MD5 is already in canonical range, so canonicalID is the identity
on them and the migration correctly leaves them alone. A new codec test pins
that invariant, since the exemptions depend on it.
Verified on a copy of a 727MB/96k-track production database: canonicalizing
those four columns changed zero rows, and artist, tag and folder ids were
themselves unchanged by the migration (only media_file ids moved, 95108 of
96666).
Introduced a typed Claims struct in core/auth to replace the raw
map[string]any approach used for JWT claims throughout the codebase.
This provides compile-time safety and better readability when creating,
validating, and extracting JWT tokens. Also upgraded lestrrat-go/jwx
from v2 to v3 and go-chi/jwtauth to v5.4.0, adapting all callers to
the new API where token accessor methods now return tuples instead of
bare values. Updated all affected handlers, middleware, and tests.
