  "summary": "Reviewed the target assembly source, which implements a constant-time bignum modular-constant routine with register saves/restores and arithmetic-only loops. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or hidden subprocess execution.\n`aws-lc/crypto/fipsmodule/ml_kem/mlkem/native/x86_64/src/rej_uniform_table.c` is an auto-generated C lookup table for ML-KEM rejection sampling, wrapped in conditional compilation and an empty fallback translation unit. I checked it 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.",
