- A logistics exception gate that reads carrier codes and free-text driver notes in one scan event and decides whether a shipment needs a human, which exception class it is, and how severe the delay looks.Jev Tools & CLIs#community#python#logisticsCommunity
- A localization pre-review gate that pairs source and target strings and judges meaning, terminology, tone, and placeholders as separate questions, so one failing dimension blocks a release without blending scores.Jev Tools & CLIs#community#python#localizationCommunity
