# Changes to Record a tool calibration: an external (vendor or customer) attestation, or an in-house
calibration with per-checkpoint measurements against the tool's current calibration template.
The server derives the result from the measurements and rejects a submitted result that
disagrees; reference gages never take calibration records. A save recording a failure
automatically opens an NCR, echoed as createdNcr. Creates are not idempotent: a retried
request records a second calibration (and opens a second NCR on a failure) — list the tool's
records before re-sending after a timeout.
