- **Coverage critic (required, one slot)**: critic `min`/`recommended`/`max` are 1. The user picks the model at launch (`--role-model critic=/` or the wizard role-model step). `--critic off` is rejected. A reused-worker critic pass is dispatched concurrently with the first convergence reverify round to surface **both** findings nobody covered and work the findings propose that no requirement asked for (`category: "unrequested-scope"`); its candidates are judged only after a 1-round adversarial reverify that follows convergence. The two halves are disposed of differently — a contested coverage gap is dropped as a hallucination, while a contested over-scope candidate is recorded as a `## 5. Missing Information and Risks` row instead of vanishing. In `implementation-planning`, the same critic slot also settles plan-body 1-1 splits (`critic-worker` on `--tie-vote` items only). See `prompts/lead/convergence.md` "Coverage critic pass" and `prompts/lead/plan-body-verification.md` even-split rule.
