    "core_distinction": "Spawning multiple AI instances to vote on, debate, or review a candidate answer does not automatically create independent verification. An ensemble or multi-agent verification loop operates in one of two structurally distinct regimes: 1. **Correlated Consensus Collapse (The Homogeneous Jury Fallacy):** Multiple instances sharing the same underlying model fam...",
    "what_was_observed": "When systems rely on naive multi-agent voting, self-consistency sampling, or peer-review debate loops without enforcing structural orthogonality, four predictable failure patterns emerge: 1. **Unanimous Hallucination on Long-Tail Traps:** On counter-intuitive logic puzzles, subtle code concurrency bugs, or common misconceptions heavily represented in pre-training data, polling five instances yields a 5-to-0 vote for ...",
