Metrics are served on METRICS_PORT (default 2112, "off" to disable), never on
the public port. Besides the Go runtime and process metrics this adds:
- http_requests_total and http_request_duration_seconds per route pattern,
from an Echo middleware.
- musicserver_songs_requested_total and musicserver_songs_played_total by
pick mode (random, low, classic). The mode is now stored with each queued
song (migration 000006, not released yet).
- Library size, sync duration, last successful sync, broken songs from the
last full sync, and the database connection pool.

Echo compares allowed origins literally, so "https://*" and "http://*" never
matched a real origin and no CORS headers were sent. The allowed origins now
come from CORS_ALLOWED_ORIGINS (comma-separated, checked at startup). When it
is empty, only same-origin requests work, which is enough for the bundled
frontend.
Credentials are no longer allowed since the API uses Bearer tokens. Browsers
may now send Range and X-Queue-Id and read X-Queue-Id and Content-Range.
The queue lived in memory and was shared by all clients, so a restart or a
finished sync cleared it. Every client now has its own queue in the new
queue and queue_song tables (added to the undeployed migration 000006).
The music endpoints return the queue ID in the X-Queue-Id header and expect
it back. A request without an ID, or with an ended one, starts a new queue.
/music/reset ends the queue and returns a new ID, and a sync ends all
running queues. Ended queues are kept as history.
The deprecated legacy routes without the /api/v1 prefix are removed.
The bundled frontend gets a token with API_PASSWORD from config.js. The server now
generates config.js from its own config, so setting API_PASSWORD on the server
container is enough.
The spec is now built from the same calls that register the routes, so it
can't drift from the router like the swag comments did (all /api/v1
routes were missing).
- /api/v1 endpoints are typed Huma operations; the spec is OpenAPI 3.1 at
/openapi.json (3.0 at /openapi-3.0.json, YAML too), docs at /docs.
/openapi and /swagger/* redirect there
- Bearer token security is declared per operation; token creation and
the new GET /api/v1/health are public
- Legacy routes use the same handlers, are hidden from the spec and keep
the Deprecation header
- /sync/reset is hidden (debug only); the /sync/new, /sync/quick and
/sync/new/full aliases are removed (use /sync and /sync/full)
- Invalid parameters return 422 (validation); every error is
{"error": "..."}; empty lists are [] instead of null
- /sync/progress is documented as progress or result (oneOf)
- Tests validate the spec and check real responses of every documented
operation against it (kin-openapi)
- Removed swag annotations, cmd/docs, echo-swagger and the swag tool
- Unit tests use an in-memory fake database (internal/testutil/fakedb),
temp folders and httptest; `go test ./...` needs no Docker or env vars
- Integration tests (build tag "integration") start PostgreSQL with
testcontainers: migrations step by step, SQL dumps (skipped if
missing) and a full sync against a real database
- Removed tests that only checked copies of the logic or had empty
bodies, the broken root integration_test.go, compose.test.yaml and
.env.test with hardcoded paths
- testMusic MP3s replaced with tiny placeholders (sync never decodes
audio), 194 MB -> 168 KB
