  "description": "A builder implements the task. A critic in a fresh context checks the diff and test output against a written checklist; failures return to the builder with REVIEW.md, and a pass goes to a human merge gate, whose rejection also returns to the builder. The loop stops when the bar passes, at its round cap, or at its dispatch budget. Builder and critic share a tier, which the validator flags; heterogeneous-critic is the same shape with the critic on another tier.",
