jgrusewski d5e1214f25 fix(sp11): B1a — saboteur GPU multiplication + SimHash state_stride
Per feedback_cpu_is_read_only, saboteur effective scale now computed
on-device:
- saboteur_generate_params kernel signature gains isv ptr +
  saboteur_intensity_mult_slot parameter
- Kernel reads `mult = fmaxf(isv[saboteur_intensity_mult_slot],
  SABOTEUR_MIN)` (sentinel-0 defense for cold-start before A2's
  controller first runs) and applies `effective_scale = base × mult`
  to perturbation generation
- gpu_experience_collector.rs launcher updated; only one call site

SimHash state_stride parameter added to lookup + update kernels —
prepares for B1c replay-time curiosity wiring against trainer.
states_buf which is STATE_DIM_PADDED=128-strided. Kernel inner loop
reads `state[i × state_stride + d]` (was `i × 42 + d`). Proj-init
kernel unchanged (writes projection, doesn't read states).

Pre-requisite for B1c (curiosity wiring) and a small atomic step
toward full SP11 production behavior.

cargo check + build clean; 6/6 SP11 GPU tests + 14/14 contract tests
still pass.

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

Usage
