  A2A Agent Card observed at /.well-known/agent-card.json on the CustomerOS documentation host.
  Provider-published by construction — served from a host CustomerOS controls (docs.customeros.ai,
  CNAME to Vercel, the company's Mintlify docs site). Nothing in this manifest is derived or
  generated; the verbatim body is saved alongside it.

  path: /.well-known/agent-card.json
  canonical: true
  host: docs.customeros.ai
  notes: >-
    Probed on every CustomerOS host. customeros.ai returns 404 for both /.well-known/agent-card.json
    and the legacy /.well-known/agent.json; app.customeros.ai returns a Cloudflare 526 (origin TLS
    failure) for both; api.customeros.ai has no A record at all. Only the documentation host serves
    a card, and the card describes the DOCS site rather than the CustomerOS API — its url,
    provider.url and documentationUrl all resolve to https://docs.customeros.ai/, and skills is an
    empty array. It is emitted by the docs platform (Mintlify), not by the product API.

    Control-path diff run per the soft-404 rule — the host returns a real 404 for unknown paths, so
    the 200 on the agent card is genuine. Verbatim body saved; no field inferred.
