+"""
+Generate Proven Alphas — NO LLM REQUIRED.
+Uses the exact structure of Alpha 15 (Sharpe 2.76) and Alpha 6 (Sharpe 2.78)
+with novel fields (AC=0-1) swapped into the value leg.
+
+Run: uv run python -m alpha_factory.generate_proven
+
+This produces expressions that are GUARANTEED to be syntactically valid
+because they use hardcoded proven structures — no LLM hallucination possible.
