{
  "summary": "Reviewed this Perl perlasm generator for SHA1 ARMv8 assembly. It only emits local assembly through `arm-xlate.pl` and contains no concrete indicators of install hooks, network or exfiltration, credential access, dynamic remote code loading, obfuscation, or persistence behavior beyond the expected build-time code generation logic.\nReviewed this AArch64 assembly implementation of `bignum_mul_8_16_base`, which performs fixed big-number multiplication and stack register save/restore. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other supply-chain indicators; none were present in the target file.\nReviewed this target file as a handwritten x86-64 assembly implementation of P-521 Montgomery multiplication. I checked for install-time hooks, hidden subprocess or network/exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence tampering, and unrelated system probing, and found no concrete malicious or supply-chain indicators.",
