JSON Schema recipe
Validation gateway - your model is the validator
Validate real payloads against the governed model itself, never a stale copy.
A seeded proof that validation and governance are the same thing here. The sample Article schema is imported, then two instance payloads are validated against the project: one passes, one fails on a missing required title and an illegal status enum value - and the failure comes back as a precise error ledger (path, property, kind, message, line, expected type). Every validation regenerates the JSON Schema live from the governed model through the same profile the exports use, so the validator can never drift from the model.
