    x-agentic-notes:
      idempotency: none published; PUT /measurements is upsert-shaped but takes no
        client idempotency key
      pagination: none; breadth is served by the 1-100 item bulk endpoints
      partial_failure: bulk responses are positional and per-item, so a failed item
        never fails the batch
      retry: userEstimationInProgress is the documented retry signal after a profile,
        measurement or closet write
