  note: >-
    Non-destructive Overlay of the enrichment pass's own findings. It never mutates the
    original contract, which is stored verbatim. Every action below adds information API
    Evangelist established from FHWA's own public repository — provenance, licence,
    contact, the self-hosted nature of the servers block, and the cross-references to the
    derived artifacts in this repository.

    description: >-
      Record that the sole server entry is a springdoc-generated localhost placeholder, not a
      hosted FHWA endpoint. This API is a self-hosted open-source component; the operator
      supplies the base URL.
    update:
      - url: http://localhost:8080
        description: >-
          Generated server url (springdoc default). FHWA operates no public instance of this
          API — it is deployed by the operator from the published repository and Docker
          Compose stack.

      Annotate the one deprecated operation with the successor pair evident in the contract.
      No sunset date is asserted, because FHWA publishes none.
    update:
      x-deprecation:
        stated-by: provider
        successor-operations:
          - postRegistration
          - postConnection
        successor-source: >-
          Inferred from the contract — this operation's own description says it performs
          registration then connection in a single call, and both component operations
          remain. FHWA states no successor and no removal date.
