# =============================================================================
# MetaFeeder · MusicBrainz — the MUSIC IDENTITY tier for MetaMesh.
#
# MusicBrainz names the *work*: album, artist, release group, cover art (via the
# Cover Art Archive) and the ids the audio tiers anchor on. Keyless, no config.
# It serves no audio and must not — pair it with a bytes tier
# (Internet Archive, Jamendo) or the delegated YouTube tier.
#
# ⚠ MusicBrainz publishes a hard 1 request/second ceiling, enforced per source
# IP — one misbehaving feeder blocks every peer behind the same NAT. The rate
# limiter is in the image; there is no knob here and there should not be.
#
# It needs, over the shared `pcs` network:
#   - the **MetaGateway** app — which must list this feeder's URL
#     (`http://metafeedermusicbrainz-feeder:8080`) in its feeders config so it gets discovered.
#     Discovery is startup-only, so restart the gateway afterwards.
#
# Everything is scoped under the `metafeedermusicbrainz-*` prefix + the per-stack `metafeedermusicbrainz` network +
# /DATA/AppData/metafeedermusicbrainz/ data root, so it installs beside the other Meta* apps with
# zero collisions.

      **The music identity tier for MetaMesh.**

      MetaFeeder · MusicBrainz names the *work* — album, artist, release group,
      cover art from the Cover Art Archive, and the ids every audio tier anchors
      on. Keyless and cheap.

      It serves **no audio**. Pair it with a bytes tier — **MetaFeeder · Internet
      Archive** or **MetaFeeder · Jamendo** — or with the delegated **MetaFeeder ·
      YouTube**: recordings matched to one MusicBrainz work converge on a single
      album page instead of fragmenting into one tile per spelling.
      **Requires:** **MetaGateway** — its meta-core stores the resolved records and
      announces them to the swarm. The gateway must list this feeder in its config.

      **La couche d'identité musicale de MetaMesh.**

      MetaFeeder · MusicBrainz nomme l'*œuvre* — album, artiste, groupe de sortie,
      pochette (Cover Art Archive) et les identifiants sur lesquels s'ancrent les
      couches audio. Sans clé.

      Il ne sert **aucun audio** : à associer à **MetaFeeder · Internet Archive**,
      **MetaFeeder · Jamendo** ou **MetaFeeder · YouTube**. **Nécessite** l'app
      **MetaGateway**.

  tips:
    before_install:
      en_us: |
        **Install order:** install **MetaGateway** first (its meta-core stores and
        announces what this feeder finds).

        **After installing this app:** in **MetaGateway**, add this feeder from the
        dashboard's *Add a feeder* box — name `musicbrainz-feeder`, URL `http://metafeedermusicbrainz-feeder:8080`.
        The gateway restarts itself: feeder discovery is startup-only.
        No API key. For anything playable, also install a bytes tier
        (**MetaFeeder · Internet Archive**, **MetaFeeder · Jamendo**) or
        **MetaFeeder · YouTube**. Pairs with **MetaListen**.
        **No web UI of its own:** configure it from the **MetaGateway** dashboard → this feeder → *configure* (the gateway proxies this feeder's config page, behind the gateway's login).

# Maison (Yundera dashboard) configuration. Read in preference to x-casaos.
# schema_version 2 is required for `folders`: an older Maison refuses the app
# outright rather than starting it without its directories.
x-compose-app:
  schema_version: 2
  # Created and chowned by Maison before any image is pulled, before any hook
  # runs and before the containers start — on the first boot and every one after.
  # Compose would otherwise create a missing bind source as a root-owned dir.
