How it uses Jev
Jev Kit includes several Jev-backed agent tools. In its document classifier, it sends up to 6,000 characters of page text to a first Choice over document families, then a second Choice over members of the chosen family with that earlier decision in state. The Python classifier reads the returned choice and confidence, applies its gates, and can request human review.

Choose a specific document type within the decided family, or the escape option.
STATE
The same page text plus already_decided, which states the selected family and its definition; the member choices come from that family.

- chasing_letter
- not_in_this_list
App workflow
- Read a page
Take text from the document page and load the caller-supplied taxonomy.
- Choose a family
Ask Jev for a document family and check the choice and confidence against the configured gate.
- Choose a member
For a supported family, ask a second Jev Choice with the first decision in state, then check the narrower answer and its confidence.
- Return a label or review signal
Return the taxonomy label when supported; otherwise report an unmatched or low-confidence result for review.
Why it is interesting
Its two-stage document taxonomy keeps choices focused. Both stages include a not-in-this-list option, so a page outside the taxonomy need not be forced into a wrong class. The code treats low confidence as a review signal rather than a final label.
