Settlement Admission Boundary (SAB): A Non-Operational Pre-Execution Admission Boundary for Settlement Finality

This publication defines the Settlement Admission Boundary (SAB) as a strictly referential, non-operational boundary object. SAB specifies a mandatory pre-execution admission condition for settlement-related payment execution in systems where execution is cryptographically final and non-reversible in normal operating mode. This record introduces no mechanisms, protocols, systems, implementations, services, or operational guidance. It provides no legal, regulatory, or compliance advice. The boundary is identified solely by its immutable specification and cryptographic digest. RIGHTS NOTE No rights to implement, derive, or operationalize are granted by this publication.
