{
  "summary": "Reviewed `aws-lc/crypto/x509/v3_lib.c`, which implements X.509 v3 extension registration, lookup, parsing, and add/replace/delete helpers. I found no concrete malicious or supply-chain indicators in this file: there are no install hooks, network or exfiltration calls, credential/secret access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed the Perl perlasm generator for the SSSE3 GHASH routines. It only constructs local x86_64 assembly text, pipes it to the repository's translator script, and emits the generated code; I found no concrete indicators of install hooks, network/exfiltration, credential access, dynamic code loading from untrusted sources, obfuscation, or persistence behavior in this file.\nReviewed the generated AArch64 GHASH/GCM assembly in aws-lc/generated-src/win-aarch64/crypto/fipsmodule/ghash-neon-armv8.S. It contains only straight-line cryptographic vector code, constant tables, and looped GHASH reduction logic; I found no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.",
