//! Ensemble pipeline validation with REAL trained DQN and PPO models.
//!
//! This test proves the full pipeline: train DQN -> train PPO -> get real
//! predictions from both -> aggregate through the ensemble's SignalAggregator
//! -> produce valid EnsembleDecision values.
//!
//! No mocks are used for model inference. The DQN and PPO are trained on
//! real 6E.FUT minute-bar data, then their actual forward passes produce
//! predictions that flow through the ensemble aggregation engine.
//!
//! Requires: `test_data/real/databento/6E.FUT_ohlcv-1m_*.dbn` to exist.
//! Run with:
//!   SQLX_OFFLINE=true cargo test --manifest-path ml/Cargo.toml \
//!     --test ensemble_real_models_validation_test -- --nocapture
