      "summary": "Reviewed `aws-lc/crypto/fipsmodule/bn/montgomery.c`, which implements Montgomery context setup, Montgomery multiplication, and conversion routines for big-number arithmetic. I checked for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed the Montgomery inverse and RR-initialization routines in `aws-lc/crypto/fipsmodule/bn/montgomery_inv.c`. The file is a deterministic big-number helper with constant-time arithmetic and assertions; I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.",
