      "summary": "Reviewed `src/int/leading_zeros.rs`, which implements `__clz*` compiler-builtins for counting leading zeros with a default bisection routine and a RISC-V-specific branchless variant. I checked for install hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",
