Fixed catalog. Explicit applicability.
Synthetic/public product explanation. Source-Control Reperformance Receipt v7 keeps the five-procedure catalog fixed while recording whether each procedure applies to each event.
Always applicable
SCR-01 source admission, SCR-02 envelope/provenance integrity and SCR-05 exception preservation.
Fact-dependent
SCR-03 applies to balance-bearing security events or any event that actually carries balance/instrument facts. SCR-04 applies to facility/project-document-dependent events and explicit missing/stale document states.
NOT_APPLICABLE is not PASS
The receipt distinguishes an irrelevant procedure from a successful control. Required balance or document evidence cannot be converted to NOT_APPLICABLE merely because it is missing.
Measurement, not assumed savings
Across one clean representative of each supported event type, the current policy has 47 applicable procedure-event cells versus 60 under an all-five-everywhere assumption. That is check-density arithmetic only, not a labor, savings, price or ROI claim.
