{
  "summary": "Reviewed the generated x86 assembly in `co-586.S`, which implements big-number Comba multiply/square routines (`bn_mul_comba8`, `bn_mul_comba4`, `bn_sqr_comba8`, `bn_sqr_comba4`). I checked for install hooks, hidden subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
