  "summary": "Reviewed the x86-64 assembly implementation of `bignum_emontredc_8n`, which is a Montgomery reduction routine that only performs register/stack setup, arithmetic, and looped limb processing. I found no concrete indicators of install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this target file.\nReviewed the x86-64 assembly implementation of `edwards25519_pepadd`, which performs field arithmetic for Edwards25519 point addition and ABI/register setup/teardown. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators in this file.",
