{
  "summary": "Reviewed `src/aead/chacha.rs`, which is a ChaCha20/QUIC helper implementation with CPU-feature dispatch, key/counter setup, and unit tests. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, or other hidden payload execution in this file.\nReviewed `tests/ecdsa_tests.rs`, which contains ECDSA signing and verification tests using fixed test vectors, PKCS#8 parsing, and in-memory key generation/validation. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration behavior, credential or secret access, dynamic code loading, obfuscation, persistence, or unrelated system probing.\nReviewed the x86_64 Montgomery arithmetic wrapper in `src/arithmetic/limbs/x86_64/mont.rs`, which contains FFI shims and bounds checks around limb-based multiply, square, scatter, gather, and power routines. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration paths, secret harvesting, dynamic code loading, obfuscation/decoding pipelines, or persistence/tampering behavior.",
