Operational permit-receipt gate (ORPRG): non-bypassable permit-before-commit control of external effects at effect boundaries

Systems and methods enforce non-bypassable, fail-closed permit-before-commit control of external-effect requests at an effect boundary between an execution substrate and one or more external interfaces. An interceptor captures each request, deterministically canonicalizes it, computes an action digest, and obtains a machine-verifiable permit receipt bound to a policy digest and epoch identifier with a time-bounded validity. Prior to commitment, the interceptor verifies receipt authenticity, authorization by digest match and / or cryptographic commitment verification, epoch-compatibility, and revocation status using signed revocation data and / or transparency-log proofs subject to policy-defined recency, including in intermittently connected environments, and may enforce scope and permit-provenance constraints. If required verification evidence is missing, stale, conflicting, or indeterminate, the external effect is denied. Optional embodiments use trusted execution boundaries, capability tokens for dual enforcement, and machine-verifiable decision, audit, and denial receipts.
