EHOX 44ns Fail-Safe: Architecture-Level HEMP Resilience and Byzantine Collusion Proof via Non-Turing Silicon
Gerhard Hirschmann · Zenodo (CERN European Organization for Nuclear Research) · 2026
Corrected benchmark document (v2, 2026-08-11) for the EHOX Silicon Interlock system. Documents hardware fail-safe behaviour against APU dropout under EW jamming / HEMP-induced kernel panic and Byzantine multi-agent collusion. Key results: 44 ns gate reaction (R5F PMU, deterministic); CBMC 198 assertions, 0 violations (DOI 10.5281/zenodo.21863401); Z3 SMT 43/43 theorems proven (T12=Byzantine, T20a=44ns bound, T23b=31-rule completeness). Formal coverage: 2^48 = 281,474,976,710,656 discrete input vectors verified via SAT reduction (coverage factor 1.88e12 vs RS105 physical test approx. 150 points). Rice Theorem boundary established: OS-based guardrails are Turing-complete, so Byzantine fault is undecidable by Rice theorem. R5F with NRULES=31 hardcoded rules is NOT Turing-complete, therefore Byzantine immunity IS Z3-provable, and CBMC 198/0 is the machine-checkable certificate. This document supersedes the draft circulated 2026-08-10 and corrects: CBMC count (198, not 195/195), hardware grade (commercial KV260, not space-grade), compliance framing (architecture alignment demonstrated, not certified compliance). Audit chain: SHA-256 NOR-Flash, api.ehox.io/epistemic, Proof #304.
