    This Overlay records the enhancements API Evangelist applies on top of the EAC JSON:API
    description. It is unusual among this catalog's overlays in that the base document is ALSO
    ours — the EAC publishes no OpenAPI — so the overlay's real purpose is to keep the
    consumer-facing guidance (traps, provenance, agent guardrails) separable from the
    probe-derived facts in the base document. Applying it does not mutate the base file.

      x-consumer-warning: >-
        The EAC does not document, announce or support this surface. It exists because Drupal's
        JSON:API module is enabled on www.eac.gov. Nothing here is a commitment by the EAC, and
        a routine CMS change could alter or remove any path without notice.

      x-agent-guidance:
        read_only: true
        write_verbs_return: 405
        safe_for_autonomous_use: true
        rationale: >-
          Every write verb returns HTTP 405 by site configuration, so no agent action against
          this surface can have a side effect. Reversibility, idempotency and dry-run are all
          `na` for that reason, not unaddressed.
        check_meta_omitted: >-
          A 200 with an empty data array plus meta.omitted means "not permitted", not "no
          records". 63 of 216 resource types behave this way.
        enumerate_from_index: >-
          Start at GET / and read the links map. Constructing paths risks an HTML 404 that will
          not parse as a JSON:API error document.

            The single most requested EAC dataset is distributed as bulk CSV/Excel/SPSS/Stata/SAS
            files catalogued in the Project Open Data document, not through this API. Agents
            asked for EAVS numbers must go there.
