I checked for install-time hooks, network or exfiltration behavior, credential/secret access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed `src/arithmetic.rs`, which is a small Rust module that wires together arithmetic submodules, exports limb helpers, and defines limb-count bounds plus a slice-length error enum. I found no concrete malicious or supply-chain indicators in this file: no install hooks, network or exfiltration paths, credential access, dynamic code loading, obfuscation, or persistence behavior.",
