Same treatment as AlbumApplicationResponse, but Track is the cleaner
case: OwnerUserId (local-only) and ExternalId (external-only) are
both genuinely exclusive to one side, so the base carries neither and
is abstract — every real value is one of the two derived types.
TrackApplicationResponse (abstract, shared fields + FromEntity dispatch)
LocalTrackApplicationResponse (+ OwnerUserId)
ExternalTrackApplicationResponse (+ ExternalId)
Hit a real gotcha along the way: the response already had an explicit
Source property, which collides with the "source" discriminator STJ's
polymorphism support injects ("contains property 'source' that
conflicts with an existing metadata property name" — only surfaced at
runtime in the Api integration tests, not at build time). Fixed by
dropping the now-redundant explicit Source field entirely; the
discriminator already serializes the identical "Local"/"YouTube"
value under the same name, so the wire contract is unchanged. Updated
the two call sites that read .Source directly (TrackSearchItemResponse
and a playlist track filter that needed flatMap instead of
filter().map() to keep the narrowing across the chain).
Musify
Music streaming platform: upload your own tracks (or import them from YouTube),
process them asynchronously (audio transcoded to .m4a, thumbnails generated)
and stream them without the bytes ever going through the API.

Run it
Development (Docker Desktop):
docker compose -f deploy/compose.yml -f deploy/compose.dev.yml up -d
Infrastructure plus stream-ticket keys, database migrations and Zitadel OIDC
provisioning — all as one-shot jobs baked into the compose file. Apps run from
the IDE by default; add --profile apps up -d --build as a second command to
run them in Docker instead.
Production, on a server with a domain:
cp deploy/.env.prod.example deploy/.env.prod # fill in the domain and secrets
docker compose --env-file deploy/.env.prod -f deploy/compose.yml -f deploy/compose.prod.yml up -d
docker compose --env-file deploy/.env.prod -f deploy/compose.yml -f deploy/compose.prod.yml --profile apps up -d --build
Idempotent — run the same commands again to deploy an update. See deploy/README.md for the details, the port map and the production prerequisites.
