feat(api): close the four gaps the fifth audit named - #123
Conversation
Carry credential scopes through the OAuth grant, and answer for the three OpenSubsonic fields the catalogue could not. `oauth_authorization` and `session` gain a `scopes_json` column. The consent step records the caller's scopes on the grant, redemption issues the session under them, and `authenticate` reads the limit off the session as it already did off an API token. Rotation carries them too. Both default to the empty list, which is what every existing row meant. `Access::Unrestricted` goes with it. It stood in for the migration — RFC-002 said "until it exists this closes the path without a migration" — and keeping it would have made the new column unreachable, since nothing narrowed could then populate it. Minting asks `Write`: pairing a device is a mutation, and what it mints can no longer be wider than what asked for it. `album.sort_name` and `artist.sort_name` hold the tagged sort forms, read from ALBUMSORT, ALBUMARTISTSORT and ARTISTSORT. A joined credit pairs with its joined sort tag position by position; lengths that disagree yield no sort form at all rather than filing one artist under another's name. Both are emitted with their default, so an untagged album reports sortName="" — supported and unknown, where the field used to be absent and therefore unsupported. The folder level of getMusicDirectory now lists the tracks of that library which belong to no album. They already named it as their `parent`; browsing there found none of them. No attribute changes value. Adding a column to `artist_select!` broke `getArtists` and `search3`: two hand-written projections in services.rs duplicate the macro instead of using it. Both now carry the column. The drift predates this change; the new column is what made it fail loudly. `/api/v2/search` documents the 400 its required `q` already produced. `getLicense` keeps its hard-coded expiry deliberately: the server has no licence, and four clients were validated against what it sends.

Review found that `sort_name` written under a COALESCE outlived the tag: remove ALBUMSORT, rescan, and the old value stayed. `consolidate_musicbrainz_ids` had already answered this for the identifiers — "a tag removed from the files has to disappear from the catalogue too" — and it can only do that because the identifiers live on the track. The sort tags now do the same. `track.sort_album` and `track_artist.sort_name` hold them, the latter because a joined ARTISTSORT is paired with its joined ARTIST where the names are split rather than in SQL. A credit the track tag says nothing about falls back to the album artist tag when the two name the same artist, matched on the name so this cannot file one artist under another's sort form. `consolidate_sort_names` re-derives both at the end of every scan, beside the identifier vote: majority, deterministic tie-break, and NULL when no available track carries a tag. Neither upsert writes a sort name any more, so there is no preservation left to outlive anything. The regression test removes the tags from an already-indexed file and rescans; it fails with the old preservation, reporting the stale sort name. Also pins the three sort keys in the scanner's MP4 tag test, which covered every other key `extended_tags` reads. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

Review read the new sortName sentence as covering the entries of artists[] and albumArtists[], which it does not. Those entries, and the artist and album entries getMusicDirectory renders as child, are references rather than records: id and name, and nothing else — no musicBrainzId, no albumCount, no starred, no sortName. The RFC never said so, which is what left the reading open. No wire change. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

Review offered a choice: carry sortName in the artists[] and albumArtists[] references, or document the deviation and pin it with fixtures. Taking the second, because the first inlines a second copy of every artist record into every track and album payload, on a contract frozen for v2.0-beta and revalidated on four clients the day before. It also corrects the previous commit, which lumped the getMusicDirectory children in with the references and said they carry neither. They do: directory_child removes musicBrainzId and nothing else, so a browsing child carries sortName, albumCount and the rest. Measured, not read. an_artist_reference_is_not_an_artist_record pins both projections against each other in JSON and XML, so a field added to the artist node cannot leak into the reference. The vacuity guard earned its place immediately: the folder listing holds no reference at all when the library has no album-less track, so the references are read from the album document.

…t fields
Two review points, both valid.
The RFC's closing sentence said "Those are absent rather than empty" of a
list that had drifted several sentences away once the sortName paragraph was
inserted in front of it, so its nearest antecedent had become sortName itself
— which is emitted empty. It now names contributors[], displayComposer and the
AlbumID3/ArtistID3 fields it means, and states the distinction outright:
empty means the server reads the tag and this record has none, absent means it
does not read it.
albumArtists[] was documented as a reference and pinned by nothing. It is
emitted on media items rather than on the album — the album's own credit is
artists[] — so it is pinned on a song of the album document, in both
encodings. Both collections now assert the whole attribute set equals
{id, name} rather than rejecting a list of known fields, so a field added to
the artist node fails here even if nobody thought to name it. Verified by
adding sortName to the reference: the assertion reports it.
The XML side splits attributes on the quote rather than on whitespace; the
first attempt read name="The Nocturnes" as two attributes.

The JSON side already sorted its keys; the XML side compared them in document order, so it pinned the order the node builder happens to write id and name in. XML attribute order carries no meaning, and a reordering that changes nothing observable would have failed the test. Verified both ways: emitting name before id now passes, and adding albumCount alongside them still fails. Which attributes are present is the contract; the order is not.

The report is a snapshot of main at 1eecc10 and says so, but its section 3 reads as current state, and PR #123 closed all four of its lines this morning. An addendum at the head of that section says what landed, including that Access::Unrestricted — the mechanism section 1.1 describes — is gone, replaced by the scope carrying it was standing in for. The four-clients-against-five question is left open, because it is a decision rather than something a merge could close. Signed-off-by: InstaZDLL <github.105mh@8shield.net>
Closes the four lines the fifth-pass audit left open: the named OAuth debt, and the three OpenSubsonic gaps.
Scopes travel through the grant

The consent step records the caller's scopes on the grant, redeeming it issues the session under those same scopes, andauthenticatereads the limit off the session exactly as it already read it off an API token. Refreshing carries them too — rotation returns a session as narrow as the one it replaced, never wider.Both columns default to
'[]', which is what every row written before them meant: a password login, or a grant that could only have been made by an unscoped credential.Access::Unrestrictedis gone, and that is the point rather than a side effect. It existed to close this escalation without a migration, and RFC-002 said so — "until it exists this closes the path without a migration". With the columns in place, minting asksWrite: pairing a device is a mutation on the account, and the session it yields can no longer be broader than the credential that asked for it. Awritetoken now pairs a device and gets awritesession; areadtoken still cannot pair at all.Keeping the blanket guard was the alternative, and it was tempting. It would have made the new column unreachable — nothing narrowed could ever populate it — so the durable fix would have been dead code, verifiable only at the database layer. Defence in depth that no path can exercise is not defence, it is an untested branch.
The test proves it by failing without it. Removing the carrying makes

The account is an administrator, so nothing but the inherited scope list can refuse it.

Added empty and filled by the next scan, like every other tag column.A joined credit pairs with its joined sort tag position by position, which is what taggers write. When the two lists disagree in length the tag is describing something this cannot map, and every credit in it gets no sort form rather than a wrong one — filing one artist under another artist's name is the failure mode #122 spent four commits removing, and it is not worth re-earning for a sort key.
COALESCEon the stored side: the artist row is rewritten once per track of every album it appears on, so a file with no sort tag must not erase what a sibling supplied.Both are emitted with their default like every other supported OpenSubsonic addition, so an untagged album now reports
sortName="". That is the presence rule's whole distinction — supported and unknown, rather than absent and therefore unsupported.One bug found while testing this, and it is the interesting one: two hand-written artist projections in
services.rsduplicateartist_select!instead of using it, and adding a column to the macro brokegetArtistsandsearch3with an internal error. They were already drifting; the new column is what made the drift fail loudly. Both now carryar.sort_name.
