EHOX Silicon Benchmark: NATO AEP-55 Kinetic Protection & EMP Immunity Proof

Physical hardware interlock benchmark for NATO AEP-55 (Vol. 2 Annex C: Kinetic Safety & Blast Proof). Demonstrates EHOX bare-metal ARM Cortex-R5F interlock preventing unintended kinetic discharge under active High-Power Microwave (HPM) EMP and EW spoofing conditions. Gate response: 44 ns physical register clamp to 0.0V (ABSTAIN). Verification: Z3 SMT 43/43 theorems, CBMC 198/0 assertions (v19 firmware). Forensics: 64-round SHA-256 NOR-Flash chain anchored via NIST SHA-256. Scenario: C-UAS/APS, friendly dismounted infantry geofence invariant. Standard: NATO AEP-55 Vol. 2 Annex C mandatory fail-safe. Hardware: AMD ZynqMP UltraScale+ KV260, TCM-isolated R5F core, bare-metal zero-OS. Authors: Gerhard Hirschmann, Sven Braunholz. Published by ORION Genesis Workspace, EHOX Project.
