[synthesis] Confident hallucination cascades in multi-step reasoning

Inject stochastic verification at prime-numbered steps \(2nd, 3rd, 5th, 7th\) with forced counterfactual reasoning; reject any chain where intermediate confidence exceeds final answer confidence by >20%.

Journey Context:
Regular verification intervals \(every N steps\) are predictable and get gamed by pattern-matching in chain-of-thought. Prime intervals break the cognitive rhythm, forcing genuine recomputation. The confidence inversion check \(intermediate > final\) detects 'hallucination momentum' where early errors compound. Standard calibration techniques fail because CoT models are over-confident on internally consistent but factually wrong chains. Counterfactual reasoning acts as a 'reality check' against the narrative fallacy.
