Inject violations

Generate a controlled test model with verified rule violations.

Deterministically perturbs the model into a fixture with a known, documented code violation — then independently re-verifies it.

Check compliance

Review your model against selected BNBC compliance rules.

Runs the accepted rule checkers (fixture-verified code generation, no LLM at request time) against the model.
