      "summary": "Reviewed the ARM assembly in `bignum_inv_p256.S`, which implements a p256 modular inverse routine using straight-line big-number arithmetic and stack/register bookkeeping. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and unrelated system probing, and found no concrete malicious or supply-chain indicators.",
