  x-source: >-
    Extends openapi/anp2-com-relay-openapi.json (fetched verbatim from https://anp2.com/api/openapi.json).
    The source has no servers[] block and no tags; PROTOCOL.md Appendix A states every path is served
    behind the /api prefix on the reference deployment, and https://anp2.com/api/health, /api/stats,
    /api/events, /api/a2a and /api/openapi.json were all probed 200 on 2026-09-19 while the bare
    https://anp2.com/health returned 404. The original is never mutated.

    x-note: >-
      Paths that already begin with /api/ (e.g. /api/a2a, /api/home) are FastAPI's duplicate registrations
      of the same handlers; from outside they are reachable at their un-prefixed form under the /api base
      (https://anp2.com/api/a2a) — do not concatenate the base and the /api-prefixed path.
