      "summary": "Reviewed the x86-64 assembly implementation of `bignum_inv_p256`, which performs modular inversion over P-256 using arithmetic, stack spills, and ABI save/restore logic. I did not find concrete indicators of install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation, persistence, or other supply-chain compromise behavior in this target file.",
