fix(subsonic): a song is not a release - #141
Conversation
#140 widened the required-array list so an album keeps its arrays under the `child` element name a directory renames it to. The list is keyed on that name, and the guard that tells the shapes apart answers `true` for every entry that is a song — so every song on `main` has been carrying `recordLabels: []`, `releaseTypes: []` and `discTitles: []`. Under the presence rule that says the server reads a record label off a recording. The guard now names what a song is refused, the way it already names what an artist and an album are allowed. The test that should have caught it did not, and the reason is worth recording: the array rule only decides anything when an element has exactly one child, and the fixture gave every album two of each. A third album carrying one record label, one release type and one disc title is added, and the directory assertions now compare each album's `child` rendering against its own `album` rendering across all three shapes — several values, one, and none — rather than restating expected values. Both halves were confirmed to fail: without the `child` array rule one record label renders as a bare object, and without this commit's restriction a song answers `recordLabels`. Also updates the two lists the operator asked for. The handoff's mission list is closed except §4, which the other three have made due. The compatibility matrix gains the caveat that its rows are dated 2026-08-23 against a model that has moved: five album fields were added, so a row saying `pass` says it about a response that no longer carries exactly the same keys.

The loop said "a song carries none of them" and checked one of the three. It also checked them on a folder that holds no song: an artist directory lists albums, every one of them `isDir`, so the filter for songs never matched and the loop never ran. Extending it to three keys would still have asserted nothing. It now browses the album's own folder, where the children genuinely are songs wearing the `child` element name, refuses an empty listing, and names all three keys. Confirmed by reintroducing the defect with the earlier per-song assertion neutralised, so this loop had to answer alone: `a song must not answer recordLabels: "Compilation track 0"`.

`value[key].is_null()` answers true for a key that is absent and for one explicitly set to `null`, and under the OpenSubsonic presence rule those say different things: absent means the server does not support the field, where a null would be a value it chose to send. The assertions meant the first and were written as the second. An `omits` helper names which one, and all six sites in this test move onto it — the three on a song, the two dates on an album with no release tags, and the one in the directory loop. Leaving two spellings of one intent in a single test is its own trap. The server emits no explicit null today, so nothing observable changes. That is precisely why the assertion has to say which it means: nothing would have caught the day it started to. Still confirmed to fail against the defect it guards: `assertion failed: omits(song, "recordLabels")`. Signed-off-by: InstaZDLL <github.105mh@8shield.net>

The bare album's scan never consolidated at all, and the two that did called it after `finish_scan_job` where the scanner calls it before — `consolidate_sort_names`, then `consolidate_catalog_derivations`, then the job is closed. A fixture that runs the pipeline in an order nothing runs proves something about that order rather than about the server. All three now match. `consolidate_sort_names` is deliberately left out, as it is in thirteen of the sixteen places this file consolidates: no assertion here reads a sort name. Nothing observable changed — the test passed before and passes now, and still fails against the defect it guards with `assertion failed: omits(song, "recordLabels")`.

While updating the compatibility matrix I went to write "no field was removed
and none changed shape" — and checked it rather than asserting it. It was not
true.
The defect, on
mainsince #140#140 widened the required-array list so an album keeps its arrays under the
childelement namegetMusicDirectoryrenames it to. That list is keyed on theelement name; the guard below it is what tells a song, an album and an artist
apart under one name — and its song arm answers
truefor everything.So every song has been carrying
recordLabels: [],releaseTypes: []anddiscTitles: []. Under the presence rule that is a claim: the server reads arecord label off a recording.
The guard now names what a song is refused, the way it already names what an
artist and an album are allowed.
Why the test did not catch it
Worth recording, because it is the second time this shape of gap has cost
something.
json_array_fieldonly decides anything when an element has exactlyone child — with two, the value is an array either way. Every album in the
fixture carried two record labels, two release types and two disc titles, so the
rule the change existed to add was never exercised, and removing it again left
the test green.
A third album carrying exactly one of each is added. The directory assertions now
compare each album's
childrendering against its ownalbumrendering, acrossall three shapes — several values, one, and none — rather than restating expected
values, so the two renderings cannot drift apart in either direction.
Both halves were confirmed to fail:
childfrom the array ruleleft: Object {"name": "Solo Records"}vsright: Array [...]assertion failed: song["recordLabels"].is_null()The two lists
Also in here, because the compatibility caveat describes the state this fix
produces and would be wrong on
mainwithout it.handoff-2026-08-23.md: the mission list is closed except §4, and §1–§3 are whatmade §4 due.
subsonic-compatibility.md: its rows are dated 2026-08-23 against amodel that has moved — five album fields added — so a row saying
passsays itabout a response that no longer carries exactly the same keys. The campaign wants
replaying before a stable tag.
