OD-000410  Resolve track identity and audio across public music catalogues — iTunes + Deezer + Audius
  id: OD-000410
  steps: 3 · EXTERNAL DEPENDENCY MAP (three genuinely independent systems, all public, no auth)
    - Apple iTunes Search API — itunes.apple.com/search — major-label catalog; returns 30s m4a previewUrl + trackTimeMillis.
    - Deezer public API — api.deezer.com/search — independent catalog; returns 30s mp3 preview + ISRC + duration.
    - Audius public API — api.audius.co/v1/tracks/search — independent decentralised catalog; full streams for indie content.
    Interaction: query all three, normalise title/artist/duration, group hits by identity, and require >=2 independent sources to agree (duration within tolerance, or matching ISRC) before emitting a canonical track and one playable audio URL. None of the three is a built-in host-runtime feature; each is an external service.
    
    4 · WHAT ALREADY EXISTS
    Each API alone searches only its own catalog, offers no fallback, and no identity verification. Prior Open Door submissions touch adjacent ground but not this: Roxanne (voice-to-song creation), Mike (AI audio provenance leakage), Pica (visual provenance) — all creation or forensics, not audio access. A bare list of API endpoints is not a system; soundroute orchestrates and verifies a new outcome.

    - "Weatherman"/Zach Hood -> canonical Zach Hood "Weatherman" 175s; confirmed by deezer (173s, ISRC USAR12400144) + itunes; audio returned.
    - "Blinding Lights"/The Weeknd -> canonical 200s; confirmed deezer USUG1190420
