  note: The table above is served by the same code that sets the headers ("there is no second place to remember to edit"); /deprecation answers Accept application/json with the same rows. Most other routes are unversioned.

  note: >-
    The provider's RFC 9727 api-catalog registers liveness.json as the `status` link relation for the HTTP
    API, so it is the provider's own declared status surface and the StatusPage pointer follows it. It is a
    live, signed "is the Worker answering and when was the keeper last provably present" document with
    fail-closed instructions — not an uptime history, not an incident log, and it says so ("infrastructure
    liveness, nothing more"). /corrections (75 dated Atom entries) is the closest thing to an incident
    record. No third-party status page exists.
