{
  "summary": "Reviewed the x86-64 assembly implementation of `bignum_montsqr_p384_alt`, which is a handwritten Montgomery-squaring routine for P-384 using register-only arithmetic, conditional moves, and normal ABI save/restore. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the target x86-64 assembly implementation of `bignum_montsqr_p521_alt`, which performs Montgomery squaring and final reduction for the P-521 field using register arithmetic and stack scratch space only. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or other supply-chain compromise signals in this file.\nReviewed `aws-lc/include/openssl/ssl3.h`, which is a plain OpenSSL-compatible TLS/SSL header defining protocol constants, record sizes, alert codes, and legacy message aliases. I found no concrete indicators of install-time execution, hidden subprocesses, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence in this file.",
