jgrusewski 71a0275f54 test(sp5): Task A3 — assert budget sum-to-1 invariant
Code-quality review caught that the two Pearl 2 unit tests verified each
output (c51, iqn, cql, ens) against its analytical expected value within
1% relative tolerance, but did NOT assert the structural invariant
`c51 + iqn + cql + ens ≈ 1.0` that the kernel maintains by construction
(`ens = max(0, 1 - iqn - c51 - cql)`).

A coefficient typo (e.g. BASE_IQN=0.111 instead of 0.11) would produce
individually-plausible per-component values that all still pass the
relative checks while quietly summing to 0.97 or 1.04. The sum check
catches that class of regression.

Adds `assert!((c51+iqn+cql+ens - 1.0).abs() < 1e-4)` inside both
per-branch loops in the flat-regime and sharp-regime tests.

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
