A computer-implemented system architecture and method for securing data at the file format level using a strict, mandatory non-amorphous structural constraints layer bound to a variable payload. A single computational sweep of the structural layer concurrently handles network state validation, utility token transactions, payload integrity hashing, and zero-knowledge privacy authentication within a hardware-isolated secure enclave. Upon detection of structural tampering, the local runtime executes an immediate self-destruct routine by overwriting active memory sectors.
