    NotModified:
      description: Not Modified — the caller's If-None-Match matches the current snapshot, so no body is sent. The ETag is derived from the cache's refresh stamp, so it changes exactly when the payload would.
  parameters:
    IfNoneMatch:
      name: If-None-Match
      in: header
      required: false
      description: A previously returned weak ETag. When it still matches the cached snapshot, the endpoint answers 304 with no body — the cheap way to poll.
