+description: >
+  The Crimson Leaf board debates their independent design reviews in 2–3
+  structured rounds, reaching consensus on required changes before polish.
+
+participants:
+  - Peter
+  - David
+  - Sarah
+  - Elena
+
+iteration_limit: 3
+convergence_signal: "CONSENSUS REACHED"
+
+steps:
+  - type: boardroom
+    loop:
+      max_iterations: 3
+      condition: until_consensus
+    hint: |
+      You are {agent.name}.
+      {agent.identity}
+
+      You have the Company Design Specification and all independent reviews above.
+
+      COMPANY DESIGN UNDER REVIEW: {task.message}
+
+      YOUR REVIEW:
+      {this_agent_review}
+
+      OTHER REVIEWS:
+      [Peter] {peter_review}
+      [David] {david_review}
+      [Sarah] {sarah_review}
+      [Elena] {elena_review}
+
+      Round {task.iteration} of the design review debate.
+
+      Respond to the other board members' most critical points:
+      - Where you agree, say so clearly and move on.
+      - Where you disagree, argue your position with specific evidence.
+      - If you've changed your mind based on someone's argument, say so.
+
+      Focus on ACTIONABLE changes. The output of this roundtable will be used
+      to polish the design specification before bootstrap.
+
+      The group must converge on:
+      1. Final verdict: GO (proceed to polish) or KILL (abandon this company)
+      2. If GO: the exact list of changes to make during polish
+      3. Any unresolved risks that must be accepted or mitigated
+
+      When the group has reached sufficient consensus for the polish step,
+      end your response with: CONSENSUS REACHED
