  Lifecycle posture for FHWA's published API-bearing software. FHWA ships open-source
  components that operators deploy themselves, so the lifecycle signal is release cadence
  on GitHub and Docker Hub rather than a hosted-service SLA. There is no status page, no
  SLA, and no deprecation policy anywhere on the FHWA estate.
versioning:
  scheme: semver-ish (carma-system-<major.minor.patch> for CARMA, <major.minor.patch> for V2X Hub)
  api_versioning: URI path segment — /prd/v2/ on the V2X App API
  current:
    - component: V2X Hub
      version: 7.11.1
      released: '2026-01-30'
    - component: CARMA Platform
      version: carma-system-4.11.0
      released: '2025-08-14'
    - component: CARMA Streets
      version: carma-system-4.11.0
      released: '2025-08-14'
    - component: V2X App API
      version: null
      released: null
      note: >-
        Untagged and unreleased — the repository has zero tags and zero releases and ships
        from `develop`. Last commit 2026-07-30.
release_cadence:
  observed: >-
    V2X Hub cut six releases between 2024-09 and 2026-01 (7.8.1, 7.9.0, 7.10.0, 7.10.1,
    7.11.0, 7.11.1). CARMA Platform cut carma-system-4.10.0 (2025-06-25) and 4.11.0
    (2025-08-14) after a fourteen-month gap.
  published_policy: false
sla:
  published: false
  note: >-
    None exists and none should be expected — FHWA operates no hosted instance of these
    APIs. The SLA belongs to whoever deploys the container.
status_page:
  present: false
  probed:
    - url: https://status.dot.gov/
      status: 000
      note: DNS does not resolve.
  note: >-
    No status page was found for FHWA or for any of its published components. No StatusPage
    pointer is emitted.
deprecation_policy:
  published: false
  sunset_header: false
  deprecation_header: false
  rfc8594: false
  note: >-
    No deprecation or sunset policy is published, and the contract declares no Deprecation
    or Sunset response headers. No Deprecation pointer is emitted.
deprecated_operations:
  - operationId: postRegistrationConnection
    method: POST
    path: /prd/v2/registration-connection
    marked: 'deprecated: true in the OpenAPI contract'
    replacement_stated: false
    sunset_date: null
    note: >-
      The only operation flagged deprecated in the contract. It combines postRegistration
      and postConnection into one call; the contract does not name a successor or a removal
      date, though the two component operations remain and are the evident path forward.
