  "summary": "Reviewed the x86-64 assembly implementation of `bignum_inv_sm2`, which is a pure modular inversion routine for the SM2 field and writes only its computed output back to the caller's buffer. I did not find concrete supply-chain or malicious indicators in this file: there are no install hooks, network or exfiltration paths, credential/secret access, dynamic code loading, obfuscation, or persistence behavior.",
