      "summary": "Reviewed `src/serde/visitor.rs`, which implements serde `Visitor` handlers for `Date`, `Duration`, `OffsetDateTime`, `PrimitiveDateTime`, `UtcDateTime`, `Time`, `UtcOffset`, `Weekday`, `Month`, and well-known offset datetime formats. I checked for install-time hooks, network or exfiltration behavior, credential access, dynamic code loading, obfuscation, and persistence tampering, and found no concrete malicious or supply-chain indicators in this file.",

      "summary": "Reviewed `src/sys/local_offset_at/imp.rs`, which is a minimal fallback implementation that always returns `None` for unsupported OS targets. 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.",
