Cap at 4 auditors total. 3. **Dispatch in parallel via background bash** -- never hand off to user. Prompt each: security findings, logic issues, reliability concerns, test gaps. ```bash codex "Review for security, logic, reliability, test gaps: <artifact>" & gemini "Review for security, logic, reliability, test gaps: <artifact>" & wait ``` 4. **Reconcile.** Deduplicate. Classify: - CONSENSUS -- flagged by 2+ auditors - CONTESTED -- flagged by 1 auditor only - PASS -- no issues 5. **Emit report** using the format below. ## Report format rule (all cross-audit outputs) Any reconciliation report presenting multiple paths MUST use this structure: ``` VERDICT <one-line converged recommendation> OPTIONS A -- <short-name>: <one-line what it is> B -- <short-name>: <one-line what it is> REVIEWER CONVERGENCE <reviewer>: <letter> <score> "<their call>" => Option <letter> -- <name> RECOMMENDATION Option <X> -- <name> because <one-sentence why>.
