{
  "summary": "Reviewed `aws-lc/ssl/tls_method.cc`, which defines TLS protocol/method factories and small state-transition helpers for SSL/TLS handshakes. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.\nReviewed this AArch64 assembly routine for 6-word big-number squaring. It is a straight arithmetic implementation with no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, or persistence behavior present in the file.\nReviewed this target ARM assembly file, which implements a constant-time Montgomery squaring routine for P-256 with inline reduction macros and final conditional subtraction. I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, or other hidden payload execution in the target file.\nReviewed `aws-lc/crypto/thread_win.c`, which implements Windows thread-local storage, one-time initialization, and SRWLOCK-based mutex helpers for AWS-LC. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators.",
