{
  "summary": "Reviewed `src/cpu/intel.rs`, which implements x86/x86_64 CPU feature detection and feature-flag initialization using CPUID/OpenSSL glue plus a small test. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence tampering, and hidden subprocess execution; none were present in this file.\nReviewed `src/arithmetic/montgomery.rs`, which implements Montgomery multiplication/squaring with CPU-specific dispatch and a fallback C/Rust FFI path. I checked for install hooks, hidden subprocesses, network or credential access, dynamic code loading, obfuscation, persistence, or other supply-chain indicators, and found no concrete malicious behavior in this file.\nThe target file is a pure Rust SHA-2 fallback implementation: it defines the compression round logic, boolean/rotation primitives, and constant tables for SHA-256/SHA-512 family hashing. I checked it for install-time hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.",
