      "summary": "Reviewed `src/field.rs`, which implements `BitField` load/store conversions for `BitSlice`, `BitArray`, `BitBox`, and `BitVec`, plus helper routines for bit shifting, resizing, and sign extension. I checked for install-time execution, subprocesses, network or exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators in this file.",
