  A2A-flavored Agent Card served at /.well-known/agent.json on withone.ai (and byte-identically on
  www.withone.ai). Grade is measured against the A2A 1.0.0 AgentCard object: 'conformant' passes every
  structural check, 'near-conformant' is correctly shaped but omits optional fields, 'flavored' fails
  a hard check and is an agent card in spirit rather than in schema. Provider-published by
  construction — served from the provider's own host; nothing here is derived or generated.
  SUPERSEDES the 2026-07-28 manifest, whose saved body was a `{"_truncated": true}` placeholder and
  whose every card field therefore read null; the real 319,620-byte document was re-fetched
  2026-09-13 and is saved verbatim beside this file.

  deviation_notes: >-
    `capabilities` is an array of eight product names (cli, knowledge, auth, flow, bridge, relay, mcp,
    agents) where A2A 1.0.0 requires an object; there is no `skills` array, no `protocolVersion` and
    no `version`. name, description and url ARE present and correct. This is a hand-authored
    machine-discovery document for LLM crawlers — it carries a full site map, an MCP block, an SDK
    block, markdown-route conventions and an inline 789-platform knowledge directory — rather than an
    A2A agent card. It is real, useful, and not A2A-shaped.

    The card points at an MCP endpoint, not an A2A one — followed through in mcp/integration-os-mcp.yml.
