The unit tests prove each method in isolation against a hand-made row.
They cannot prove the thing that actually broke this project once: that
the pieces are CONNECTED. `source_wiring` shipped a registry whose
sockets were empty and every test stayed green, because a pure-function
test has no bound user and a structural gate only proves the OLD path is
gone.
So this walks it: sweep a real page off the server, write it through the
same mapping the sync will use, bind the source exactly as the app binds
it, then claim -> tracks -> meta -> artwork -> playback, and finish by
pulling real bytes through the url the source produced. Nothing is
asserted from a type; everything is asserted from a server's answer.
The assertion with the most teeth is the identity round trip. A queue
row as `cached_to_queue_track` builds it — namespaced id plus the
server's id in the hint — must claim back to the server's id, and the
same row must ALSO resolve with no hint at all, through the cache. Those
are the two shapes a producer can hand over, and a mismatch between them
is bug 2 wearing a new source's clothes.
`assert_serves_audio` issues a Range request, which is what the
progressive feeder does: it checks seekability, refuses a chunked
(transcoding) answer, runs the Subsonic error-envelope guard over the
body, and keeps the test to 64 KB instead of a 100 MB FLAC.
Against the bench, 3/3:
jellyfin swept 500 of 4924 -> album "...And Justice For All",
9 tracks, tier "hires", cover image/jpeg (tokenless,
self-keying), stream 206 audio/flac
subsonic navidrome openSubsonic=true, swept 500 -> album
"POWERS OF VOICE (Disc 1)", 13 tracks, tier "cd",
cover image/webp keyed on subsonic:al-…_0 rather than on
the credentialed url, stream 206 audio/flac
registry each namespace routed to its owner, and a Plex id still
goes to Plex
The third needs no server and runs everywhere.
