      "summary": "Reviewed the Perl x86 assembler-backend generator in `aws-lc/crypto/perlasm/x86gas.pl`, which mainly rewrites opcodes, labels, and section directives for different object formats. I checked for install-time hooks, subprocess or shell execution, network or secret access, dynamic code loading, obfuscation/decoding, and persistence tampering, and found no concrete malicious or supply-chain indicators.",
