jgrusewski 697bb586d0 test(alpha): kill-criteria GPU smoke matching hand-computed observations
Adds the second of the two Phase E.1 kernel smoke tests in
alpha_kernels.rs (companion to the munchausen_target smoke from
91d1a52b9). End-to-end exercises the alpha_kill_criteria_compute_kernel
launcher with synthetic inputs covering all 4 outputs:

  q_values = [[1, 2, 3], [5, 5, 5]]   →  q_spread        ≈ 0.2041
  action_counts = [10, 30, 60]        →  action_entropy  ≈ 0.8980
  rollout_R=100, isv[547]=-5185,
                 isv[548]=4953       →  return_vs_random ≈ 1.0670
  q_init=50, q_early=55              →  early_movement   = 0.1000

ISV buffer is sized to 552 floats with slots 547/548 populated using the
committed Task 7c baseline values — this exercises the production
slot-indexing path through the kernel's
`isv[random_baseline_mean_slot]` / `isv[random_baseline_std_slot]` reads,
not just isolated kernel arithmetic.

Does NOT chain apply_pearls_ad_kernel afterward — the smoothing path is
canonical SP4 applicator territory already covered elsewhere. This test
isolates the kill-criteria producer arithmetic.

Tolerance 0.01 on all four observations; passes on RTX 3050 Ti in <2s
including kernel JIT.

`cargo test -p ml --lib alpha_kernels`: 3 pass (compile witness + both
GPU smokes). Audit doc docs/isv-slots.md updated per Invariant 7.

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
