      "summary": "Reviewed `src/ext/numerical_std_duration.rs`, which only defines a sealed extension trait for converting `u64` and `f64` values into `std::time::Duration` with straightforward arithmetic, overflow checks, and nonnegative assertions. I found no install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, or persistence mechanisms in this file.",
