  "summary": "Reviewed the ARM64 assembly in `aws-lc/third_party/s2n-bignum/arm/p384/unopt/p384_montjadd.S`, which implements P-384 Montgomery-Jacobian point addition plus helper routines for field multiply, square, and subtraction. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise patterns; the file is limited to local arithmetic, register/stack management, and conditional selection of computed values.",
