jgrusewski 0bbe97ed85 feat(dqn-v2): D.4c conviction consistency bonus — reward stable pre-entry deliberation
Plan 3 Task 6c.

Portfolio-state tail-append:
- PS_PRE_ENTRY_CONVICTION_EMA = 41 (EMA mean of conviction_core during Flat)
- PS_PRE_ENTRY_CONVICTION_VAR_EMA = 42 (EMA of squared deviations)
- PS_STRIDE 41 -> 43
- All 6 hardcoded-stride sites migrated in lockstep

Producer (experience_kernels.cu Flat branch):
- Per-bar EMA update alpha=0.05 (matches Task 1 reward-ema convention)
- Welford-style: delta = c - mean; var_ema = (1-alpha)*(var + alpha*delta^2)

Consumer (experience_kernels.cu entering_trade block):
- ratio = stddev/mean; stability = clamp(0, 1, 1 - ratio/0.2)
- Fires only when ratio < 0.2 (stable pre-entry conviction)
- bonus = shaping x vol_proxy x stability x conviction_core
- All multiplicands in [0,1] except vol_proxy (<=0.01); max bonus ~ 0.01
- Mirrors B.2 novelty-bonus structure — one bounded shape replaced (novelty -> stability)
- rc[5] += bonus; both EMA slots reset at entry, reversal, fold/episode boundary

Per pearl_one_unbounded_signal_per_reward.md: exactly ONE unbounded
multiplicand (vol_proxy); all others bounded. No `q_scale x |reward|`
style blowout possible.

No new ISV slot.

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
