Review rev_fd46676ef9254cebb32c304f9be2aade

{
  "summary": "Reviewed `src/crypto/aws_lc_rs/pq/mlkem.rs`, which is a small ML-KEM key-exchange wrapper around `aws_lc_rs::kem` that generates encapsulation/decapsulation keys, derives shared secrets, and gates use to TLS 1.3. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution in this file.\nReviewed `src/manual/implvulns.rs`, which is a prose-only Rust documentation block describing historical TLS implementation vulnerabilities and rustls's state-machine approach to preventing them. I checked for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and hidden subprocess execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed `src/manual/features.rs`, which is a documentation-only module describing rustls feature support, explicit non-features, and the rationale for not exposing arbitrary custom TLS extensions. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `src/tls13/mod.rs`, which defines TLS 1.3 cipher-suite metadata and helper routines for constructing RFC 8446 CertificateVerify messages. I checked this file for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.\nReviewed `src/crypto/hpke.rs`, which defines HPKE suite, key, and stateful sealing/opening traits plus key containers and zeroization for the private key. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",
