{
  "summary": "`src/num_fmt.rs` contains low-level numeric formatting helpers and stack-backed string builders, with some `unsafe` UTF-8 and pointer arithmetic used strictly for in-memory digit formatting. I reviewed it for install-time execution, network/exfiltration, credential access, dynamic code loading, obfuscation/deobfuscation, and persistence, and found no concrete malicious or supply-chain indicators.\nReviewed `src/serde/visitor.rs`, which defines Serde visitors for `Date`, `Duration`, `OffsetDateTime`, `PrimitiveDateTime`, `UtcDateTime`, `Time`, `UtcOffset`, `Weekday`, and `Month`, plus a macro for well-known `OffsetDateTime` formats. I checked for install hooks, subprocess execution, network/exfiltration, credential access, dynamic code loading, obfuscation, and persistence behavior, and found no concrete malicious or supply-chain indicators.",
