jgrusewski cfc44be13c fix: capture graph_mega at step 0 + remove MSE graph switch
Two root causes of cross-process non-determinism fixed:

1. MSE→C51 graph switch: graph_forward_mse and graph_forward were
   captured in different sessions with different cublasLtMatmul configs.
   Fix: always use blended graph_forward (c51_alpha controls blend).
   Deleted LossMode enum, graph_forward_mse, and all switching code.

2. Multiple capture sessions at steps 0-2: graph_forward, graph_ddqn,
   and graph_adam were captured individually before graph_mega at step 2.
   Each capture contaminated cuBLAS internal state.
   Fix: capture graph_mega at step 0 (single capture session).

Result: runs with same initial cublasLtMatmul capture are fully
bit-identical across all 30 epochs. Remaining cross-process variation
is from the single initial cublasLtMatmul call during graph capture.

ml

10-model ML ensemble for the Foxhunt HFT system, built on Candle v0.9.1.

Models

  • DQN (Rainbow) — deep Q-network with prioritized replay, dueling heads, noisy nets
  • PPO — proximal policy optimization with GAE, LSTM policies, clip-higher
  • TFT — temporal fusion transformer for multi-horizon forecasting
  • Mamba2 — state space model for sequence prediction
  • Liquid Networks — biologically inspired networks for non-stationary data
  • TLOB — transformer-based limit order book analysis
  • KAN — Kolmogorov-Arnold networks
  • xLSTM — extended LSTM architecture
  • TGGN — temporal graph neural network
  • Diffusion — diffusion-based generative model

Key Modules

  • ensemble — model ensemble coordination and confidence aggregation
  • hyperopt — PSO-based hyperparameter optimization with per-model adapters
  • trainers — unified training loops (DQN, PPO, supervised)
  • inferenceInferenceAdapter trait for prediction
  • checkpoint — model checkpointing and restoration
  • evaluation — walk-forward evaluation pipeline
