Lab: Watch a Real Model Extract to JSON

You built the field extraction, schema validation, repair and reconciliation as deterministic code. Now watch a real model read messy text and draft the structured JSON, live on your device.

The on-device model is small, so it may add prose or bend the schema. That is exactly why the validate-and-repair and reconcile steps you built still matter: the model drafts, and your code guarantees the shape.
