{
  "summary": "Reviewed this generated AArch64 assembly implementation of `_beeu_mod_inverse_vartime`, which performs modular inverse arithmetic and stack register save/restore only. I found no concrete malicious or supply-chain indicators in the file: no install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or hidden subprocess execution.\nReviewed the generated AArch64 assembly in `p256_beeu-armv8-asm.S`, which implements `beeu_mod_inverse_vartime` for modular inversion in AWS-LC. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden payload execution, and found no concrete malicious or supply-chain indicators in this file.\nReviewed the generated AArch64 assembly in aws-lc/generated-src/win-aarch64/crypto/fipsmodule/p256_beeu-armv8-asm.S. It appears to implement a finite-field modular inverse routine using only register arithmetic, stack save/restore, and a normal return path; I found no concrete indicators of install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence tampering.",
