          The OData CSDL document at {org}.api.crm.dynamics.com/api/data/v9.2/$metadata is the
          authoritative machine-readable schema for a Dataverse environment. It is per-tenant and
          requires a bearer token, so it cannot be harvested into this repository.

        note: >-
          Microsoft documents that a small set of internal system metadata operations is excluded
          from licence entitlement counting; service protection limits still apply.

      x-discovery: >-
        This is the runtime table catalogue. An agent should call it before attempting any typed
        read or write, because the Dataverse entity set is defined per environment.

      x-agentic-access:
        action-class: connected
        consequence: read
      x-purpose: >-
        Resolves the calling principal (UserId, BusinessUnitId, OrganizationId). Use it as the
        connection smoke test before any write, and to attribute audit trails.
