  "summary": "Reviewed the macOS x86 GHASH/CLMUL assembly implementation in the target file. It consists of generated crypto routines and constant data only; I found no concrete indicators of install hooks, network or exfiltration, credential access, dynamic code loading, obfuscation, or persistence behavior.\nReviewed this generated x86-64 assembly implementation of `_beeu_mod_inverse_vartime`, which performs finite-field arithmetic and stores its result through the caller-provided output pointer. I checked the file for install hooks, external calls, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other hidden payload behavior and found no concrete supply-chain indicators.\nReviewed the x86-64 assembly implementation of `bignum_montsqr_p521`, which performs Montgomery-style squaring and final reduction for P-521 using only register arithmetic and stack temporaries. I checked for install-time hooks, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, persistence, and other hidden payload behavior, and found no concrete malicious or supply-chain indicators in this file.",
