      "summary": "Reviewed the benchmark helper in `benchmarks/rand09.rs`, which defines a small `StepRng` and uses `rand09::Rng` to benchmark random generation for several `time` types. I checked for install-time execution, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
