  "summary": "Reviewed `aws-lc/third_party/s2n-bignum/s2n-bignum-imported/arm/curve25519/bignum_sqrt_p25519_alt.S`, which is an ARM assembly routine for computing a modular square root and Legendre/Jacobi symbol modulo p_25519 using local arithmetic and subroutine calls within the same translation unit. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering in this file.\nReviewed `aws-lc/generated-src/win-x86/crypto/fipsmodule/x86-mont.asm`, a generated Windows x86 Montgomery multiplication routine for AWS-LC/BoringSSL. I found no concrete malicious or supply-chain indicators: the file stays within arithmetic/crypto assembly and lacks install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior.",
