      "summary": "This build-tagged Go helper parses test vectors and converts Quotient and ModExp cases into hashed fuzzer corpus files under a caller-supplied directory. I checked it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",
