The hyperopt preload_data() created a loader with default hyperparams (mbp10_data_dir=None), so MBP-10/trades data was never loaded. Each trial then set mbp10_data_dir → state_dim=51, but the preloaded data had no OFI features → shape mismatch [128,43] vs [51,1024]. - Pass mbp10_data_dir/trades_data_dir to preload hyperparams - Extract ofi_features from loader after preload - Store as preloaded_ofi_features: Option<Arc<Vec<[f64;8]>>> - Inject into each trial's DQNTrainer before training Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
