      "summary": "Reviewed `src/int/specialized_div_rem/asymmetric.rs`, which defines a macro-generated unsigned division/remainder routine for asymmetric integer widths using arithmetic and `unsafe` calls to other division helpers. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration logic, credential access, dynamic code loading, obfuscation, persistence, or unrelated system probing.",

      "summary": "Reviewed `src/int/specialized_div_rem/binary_long.rs`, which defines the `impl_binary_long!` macro for unsigned binary long-division routines and contains one active restoring SWAR implementation alongside commented algorithm notes and alternatives. I checked the executable path for install hooks, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence, and found no concrete malicious or supply-chain indicators.",
