      "summary": "Reviewed the ARM64 assembly routine for modular multiplication over p521; it contains only deterministic arithmetic, register save/restore, and stack frame setup/teardown. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain behavior in this target file.",
