  "summary": "Reviewed the x86-64 assembly implementation of `sm2_montjmixadd`, which performs SM2 mixed Jacobian point addition with ABI setup, stack/register save-restore, and finite-field arithmetic macros. I found no concrete indicators of install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence in this file.\nReviewed the ARM assembly implementation of `edwards25519_epadd`, which is a handwritten field-arithmetic and point-addition routine for edwards25519. I checked for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
