Review rev_354470115c15457fbfdc84dd67ef1e80

{
  "summary": "Reviewed `tests/hkdf_tests.rs`, which contains HKDF test cases and a small helper wrapper for output-length validation. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/bits.rs`, which is a small bit-length utility module for conversions and rounding helpers. I checked for install hooks, subprocess or network/exfiltration behavior, credential or environment access, dynamic code loading, obfuscation, and persistence; none are present in this file.\nReviewed `src/digest/sha1.rs`, which is a straight SHA-1 block-compression implementation with round constants, message schedule expansion, and state updates. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed `src/prefixed.rs`, which defines Rust macros for applying a consistent symbol-name prefix to extern functions, statics, and exported items. I checked this file for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/decoding, and persistence tampering, and found no concrete malicious or supply-chain indicators.\nReviewed `src/polyfill/array_flat_map.rs`, which implements a small `ArrayFlatMap` iterator wrapper plus tests for length overflow and byte-order mapping. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration code, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.",
