      "summary": "Reviewed `aws-lc/crypto/fipsmodule/rand/asm/rndr-armv8.pl`, a Perl perlasm generator that emits ARMv8 RNDR assembly via the local `arm-xlate.pl` helper and writes it to the requested output. I checked for install hooks, network or exfiltration, credential access, hidden downloads, dynamic code loading beyond the expected local codegen pipe, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",
