    Served from the documentation host, not the apex or the API host. The apex
    (orthogonal.com, www.orthogonal.com), the API host (api.orthogonal.com) and
    the MCP host (mcp.orthogonal.com) all return 404 for both the canonical
    /.well-known/agent-card.json and the legacy /.well-known/agent.json.
conformance:

  protocol_version: '0.3'

  deviations:
  - id: supportedInterfaces-instead-of-additionalInterfaces
    note: >-
      Card uses `supportedInterfaces[]`; A2A 1.0.0 names this field
      `additionalInterfaces`. Not a hard-check failure, but a real spec deviation
      an A2A client keyed to 1.0.0 will not read.
  - id: protocolVersion-not-fully-qualified
    note: 'Declares "0.3" rather than a patch-qualified "0.3.0".'
  - id: skills-tags-empty
    note: The single skill declares an empty tags[] array, so it is not discoverable by tag.

    The skill URL resolves (HTTP 200) to a real published SKILL.md — saved
    verbatim at skills/orthogonal-wellknown-agent-skill.md. The card is therefore
    a working discovery chain, not a dangling pointer.
