        Dispatches the prompt through up to 4 strategies:

        1. SELF-CONSISTENCY (Wang et al. 2022) — single model, k=5, majority vote

        2. QUORUM-WEIGHTED — k=5 across diverse models/temperatures

        3. CHAIN-VERIFY — zero-shot CoT + verification pass

        4. SOLVE-AND-EXPLAIN — structured step-by-step with double-check


        An oracle picks the strategy with highest internal answer agreement.

        Returns signed receipt with per-strategy answers and confidence scores.'
