Review Summary

`src/rand.rs` is a small helper module that only allocates buffers and forwards to an injected `SecureRandom` implementation to produce random `Vec<u8>`, `u32`, and `u16` values. I reviewed it for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators. Reviewed `src/manual/mod.rs`, which is a documentation-only Rust module index that re-exports several manual sections via `#[path]` attributes. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file. `src/msgs/alert.rs` is a small Rust TLS codec for `AlertMessagePayload`, encoding and decoding an alert level plus description with a strict empty-tail check. I reviewed it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, and hidden subprocess use, and found no concrete malicious or supply-chain indicators. `src/key_log.rs` defines the `KeyLog` trait and a no-op `NoKeyLog` implementation for TLS secret logging, with an explicit note about `SSLKEYLOGFILE` behavior. I checked it for install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators, and found none in this file. `src/msgs/ccs.rs` defines a small TLS ChangeCipherSpec payload codec that serializes a single byte `1` and rejects any other value during parsing. I checked this file for install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.
