Extract and validate

Let Jev propose or select candidate field values; deterministic validators own schema, ranges, and rejects.

Hands-on: candidate fields, then code validates

Pattern

1. Define the schema in code (types, enums, ranges).
2. Ask Jev for candidates (Choice among known fields, Score for quality, Noul for “present?”).
3. Run local validators (Zod, JSON Schema, DB constraints).
4. On failure → repair loop, ask clarifying questions, or human review.

Why not “extract everything as free text”

Free-form extraction invites silent schema drift. Candidate + validate keeps System One in the semantic lane and code in the contract lane. Community tools that pair Zod with Jev follow the same idea—use them as inspiration, verify against your stack.
