  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ml_kem/mlkem/kem.c`, which implements ML-KEM key checking, keypair generation, encapsulation, and decapsulation with FIPS-oriented consistency checks and zeroization. I found no concrete indicators of supply-chain compromise or malicious behavior in this file: there are no install hooks, network or exfiltration paths, hidden downloads, dynamic code loading, obfuscation/deobfuscation, or persistence/tampering logic.\nReviewed this x86-64/AVX2 assembly implementation of the ML-DSA inverse NTT, including its ABI glue, stack save/restore, and modular arithmetic/data loads. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in the target file.",
