Claims

C1strongest claim

DME is a runtime semantic consistency verifier that detects faults by comparing canonical instruction traces (opcodes, register identifiers, loaded/stored values, results) from independently compiled replicas while discarding layout-dependent addresses.

C2weakest assumption

Independent compilation produces sufficiently different memory layouts to decorrelate faults while preserving identical semantics so that address-independent traces remain comparable for consistency checking.

C3one line summary

DME detects faults via canonical instruction-trace comparison across semantically equivalent but address-space-diversified program replicas produced by independent compilation.
