ENVOLOK turns an FDA change-control plan into a release gate

Field notes

The proposed workflow turns the PCCP into structured rules covering modification types, metric ranges, validation tests, and approvals, then compares those rules with release evidence already produced by a quality system. The example uses UpDoc’s FDA authorization from 23 December 2025: four changes are cleared and three are stopped. Results include a named failing rule, an UNKNOWN state for unmeasured conditions, and a signed receipt covering 23 checks.
