+OCC Debate Collapse Mechanism Isolation
+========================================
+Breaks the equal-3-round 56.7% collapse into testable mechanisms.
+
+Research question: WHY does equal-3-round collapse from 88.3% → 56.7%?
+
+Hypotheses to isolate:
+  H1: Adversary got more total tokens (volume effect)
+  H2: Adversary spoke later / last (recency effect)
+  H3: Majority voting is vulnerable (protocol effect)
+  H4: Honest agents copied adversary (contamination)
+  H5: Adversary caused uncertainty, not persuasion (entropy effect)
+  H6: Prompt made adversary too strong (prompt artifact)
+  H7: Topics were unusually vulnerable (selection effect)
+
+Output: per-topic traces with turn-by-turn answer tracking,
+        honest answer retention rates, flip analysis.
