jgrusewski 9223795c70 Merge adaptive-learning-rootcause: distillation collapse fix + env-unify design
Brings the 4-commit work from wip/adaptive-learning-rootcause into main:

  24f96ab78  fix(n1): distillation now actually pulls weights during collapse
  f21a7d661  test(e1): 20-epoch smoke test + raw-q_gap assertion + disable early-stop
  a3fd02a95  fix(early-stop): log real training epoch, not internal call counter
  9dbd8d7e9  docs(design): unify training and validation environments

Key outcomes:
- Distillation mechanism now actually pulls weights during collapse (fixed
  three bugs: epoch-boundary grad_buf erasure, CUDA-graph scalar baking,
  wrong q_gap signal at snapshot gate). E1 smoke test passes deterministically.
- Design doc lays out the next step: unifying training and validation env
  kernels so validation Sharpe tracks training Sharpe (currently diverges
  catastrophically by ~-150 absolute).
- Incidental: early-stopping log now reports the real training epoch
  instead of its internal call counter.

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
