      "summary": "Reviewed `aws-lc/crypto/fipsmodule/bn/montgomery.c`, which implements Montgomery-context setup and Montgomery modular multiplication/reduction for BIGNUMs, including a platform-specific s2n-bignum fast path. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration paths, credential/secret access, hidden downloads, dynamic code loading, obfuscation, or persistence behavior.",

      "summary": "Reviewed the Montgomery inverse and RR-initialization routines in `aws-lc/crypto/fipsmodule/bn/montgomery_inv.c`. The file is straightforward constant-time big-number arithmetic for Montgomery setup, and I found no concrete indicators of install-time execution, network or credential access, dynamic code loading, obfuscation, hidden subprocesses, or persistence behavior.",
