//! 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.
