USE CASE / Choice + Score

Document review triage

Choose fast path, request more data, or human review

A representative input (state)

Document, provenance, and applicable policy

Question type

Choice + Score

Question instruction

Choose fast path, request more data, or human review

When below threshold

Code validates required fields before queueing

Separate missing fields from hard judgments

A missing purchase-order number is a deterministic validation failure; ambiguous terms may need semantic judgment. Check format, access, amount, and duplicates before Choice routes to completion, data gathering, or review. A model result is not payment approval.

Three edge cases to test

  1. Missing PO number: request data
  2. Amount mismatch: rule block and review
  3. New layout with valid fields: test false alarms

  "state": "Invoice missing purchase order number.",
  "model": "jev-latest",

    "decision": {
      "type": "choice",
      "instructions": "Which review path should this document enter?",
      "criteria": {
        "fast": "All required information is present",
        "missing": "Required information is absent",
        "review": "An ambiguous or high-impact issue needs a person"
      }
    }
  }
}

Limits and fallback

High-impact legal or financial decisions still need qualified owners.
