{
  "summary": "Reviewed `aws-lc/crypto/fipsmodule/ml_dsa/mldsa/packing.h`, which is a C header declaring ML-DSA packing/unpacking interfaces and their contract annotations. I found no concrete indicators of install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed the CMake module that generates Rust bindings via `bindgen-cli`, including its header discovery, wrapper generation, and custom command invocation. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network/exfiltration calls, credential access, dynamic code loading, obfuscation, or persistence/tampering behavior.\nReviewed the AArch64 assembly in `aws-lc/crypto/fipsmodule/ml_kem/mlkem/native/aarch64/src/rej_uniform_asm.S`, which implements rejection sampling for ML-KEM uniform coefficient generation and is marked as auto-derived from mlkem-native. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration paths, credential or environment access, dynamic code loading, obfuscation/deobfuscation, or persistence behavior.\nI reviewed this x86-64 assembly implementation of `bignum_madd_n25519`, which performs a modular multiply-add for Curve25519/Ed25519 field arithmetic and then stores the reduced result. I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in the target file.\nReviewed `aws-lc/crypto/fipsmodule/ml_kem/mlkem/native/x86_64/src/poly_decompress_d10.S`, an auto-derived AVX2 assembly routine for Kyber polynomial decompression that consists of fixed SIMD loads, bit-manipulation, and stores. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.",
