notes: >-
  Probed every Immutable host reachable from apis.yml and the OpenAPI servers[]
  blocks — www.immutable.com, immutable.com, api.immutable.com,
  api.sandbox.immutable.com, hub.immutable.com, auth.immutable.com,
  passport.immutable.com, rpc.immutable.com — on BOTH /.well-known/agent-card.json
  and the legacy /.well-known/agent.json. Exactly one host serves a card:
  docs.immutable.com, at the canonical A2A 1.0.0 path, returning
  application/json that parses as a JSON object with real AgentCard shape.
  The card is emitted by Immutable's documentation platform rather than by an
  Immutable product team, which is why `name` and `provider.organization` read
  "Documentation" instead of "Immutable"; that is recorded as a deviation below,
  not treated as a disqualification, because the document is genuinely served
  from a host Immutable controls.
