{
  "summary": "Reviewed `aws-lc/crypto/perlasm/ppc-xlate.pl`, a Perl-based PowerPC assembly translation script that rewrites mnemonics and emits platform-specific directives for the build. I found no concrete malicious or supply-chain indicators in the target file: no install hooks, no network or exfiltration behavior, no credential or secret access, no hidden dynamic code loading, no obfuscation/packing, and no persistence or environment tampering.\nReviewed an auto-derived AArch64 NEON assembly routine for Kyber/ML-KEM base multiplication and its prologue/loop/epilogue; it only performs arithmetic and bounded loads/stores on the declared buffers. I found no concrete malicious or supply-chain indicators in this file, and no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed `aws-lc/crypto/fipsmodule/bn/shift.c`, which implements big-number left/right shift, bit set/clear, mask, and low-zero-bit counting helpers. I found no concrete malicious or supply-chain indicators in the target file: there are no install hooks, network or exfiltration paths, credential/secret access, dynamic code loading, obfuscation, or persistence behavior.",
