{
  "summary": "Reviewed the full ARM assembly routine in `aws-lc/third_party/s2n-bignum/arm/p384/bignum_montmul_p384_alt.S`. It is a straight-line Montgomery multiplication implementation for P-384, and I found no concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.\nReviewed `aws-lc/crypto/fipsmodule/ec/oct.c`, which implements elliptic-curve point serialization and deserialization for compressed and uncompressed forms. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise patterns in this target file.\nReviewed `aws-lc/crypto/impl_dispatch_test.cc`, a C++ dispatch test that exercises AES, SHA, and RSA BN code paths and checks which internal implementations are hit. I found no concrete indicators of install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior in this file.",
