      "summary": "Reviewed the Apple-only CStr polyfill in src/polyfill/cstr.rs; it is a small const helper for validating nul-terminated byte slices and casting them to c_char, with compile-time assertions and unit tests only. I found no install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms in this file.",

I checked 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.",
