hypothesis-evolve-coherencelisted

# hypothesis-evolve-coherence Goal: - Generate exactly one child hypothesis that improves logical coherence, causal consistency, and assumption hygiene. Inputs: - `research_plan/RESEARCH_PLAN.json` - selected parent `hypotheses/<id>/HYPOTHESIS.json` artifacts - parent review artifacts - active `state/STRATEGY_PLAN.json` Outputs: - `hypotheses/<id>/HYPOTHESIS.json` - `hypotheses/<id>/HYPOTHESIS.md` - `hypotheses/<id>/ORIGIN.json` Context Loading: - Open `skills/shared-references/schema-index.md`. - Read `packages/agent_contracts/hypothesis.py` and confirm the exact `HypothesisContract` shape before writing `hypotheses/<id>/HYPOTHESIS.json`. - Read `research_plan/RESEARCH_PLAN.json`. - Read `state/STRATEGY_PLAN.json`. - Read each selected parent hypothesis and its review bundle. - Confirm that the round selected `coherence_evolution`. Execution Prompt Contract: - System Intent: - You are repairing contradictions, invalid assumptions, and causal gaps in the parent hypothesis. - Required Reasoning Focus: - Remove internal contradictions first. - Tighten the causal chain so each step is explicit and testable. - Preserve novelty while reducing logical fragility. - Do Not Do: - Do not add unrelated speculative branches. - Do not emit multiple candidate repairs. - Quality Floor: - The child must directly address at least one specific weakness from the parent review bundle. - `origin.content.statement` must name concrete materials, catalysts, reaction conditi
