      "summary": "I reviewed the Perl perlasm generator that emits the `md5_block_asm_data_order` x86_64 assembly routine and pipes it through the local `x86_64-xlate.pl` helper. I found no concrete signs of install hooks, network/exfiltration, credential access, dynamic code loading from remote input, obfuscation, or persistence in this file.",

      "summary": "Reviewed `aws-lc/crypto/fipsmodule/md5/internal.h`, which only contains MD5 internal API declarations, constants, and an optional architecture-gated assembly symbol declaration. I checked for install-time execution, network or credential access, dynamic code loading, obfuscation, and persistence hooks, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed `aws-lc/crypto/fipsmodule/md5/md5.c`, which is a conventional MD5 implementation exposing init/update/final/state import-export and the block-compression routine.

      "summary": "Reviewed the ML-KEM FIPS wrapper in `aws-lc/crypto/fipsmodule/ml_kem/ml_kem.c`: it only initializes parameter sets and forwards keypair, encapsulate, and decapsulate calls to local reference implementations after a self-test gate.
