      "summary": "Reviewed `src/int/specialized_div_rem/norm_shift.rs`, which defines a Rust macro for computing a division normalization shift using `leading_zeros` or a local bisection fallback. I checked it for install-time execution, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",

      "summary": "`src/int/specialized_div_rem/trifecta.rs` defines a macro that generates optimized unsigned division-and-remainder routines using local arithmetic branches and helper multiplications. I reviewed it for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, persistence, and other hidden execution paths, and found no concrete malicious or supply-chain indicators.",
