Replace OnceLock<Ptx> + compile_ptx_for_device() with include_bytes! + Ptx::from_binary() in 13 Rust files: - gpu_action_selector.rs (epsilon_greedy) - gpu_statistics.rs (batch_statistics) - gpu_training_guard.rs (training_guard) - signal_adapter.rs (signal_adapter) - gpu_monitoring.rs (monitoring_reduce) - gpu_curiosity_trainer.rs (curiosity_training) - gpu_attention.rs (attention forward + backward) - gpu_backtest_evaluator.rs (env, metrics, gather, ppo, supervised, dqn) - gpu_experience_collector.rs (experience, nstep, her_episode) - gpu_her.rs (her_episode, her_relabel) - gpu_iql_trainer.rs (iql_value) - gpu_iqn_head.rs (iqn_dual_head) - gpu_ppo_collector.rs (ppo_experience) Remaining runtime compilation: inline utility kernels in gpu_dqn_trainer.rs (grad_norm, adam, ema, saxpy, zero, etc.) — small kernels that compile in ms. 883/887 tests pass (4 pre-existing failures in data_loader/hyperopt).

ML Models
Four production model architectures on Candle v0.9.1 with CUDA:
- DQN Rainbow -- Deep Q-Network with prioritized replay, dueling heads, noisy nets
- PPO -- Proximal Policy Optimization with GAE and LSTM policies
- TFT -- Temporal Fusion Transformer for multi-horizon forecasting
- Mamba2 -- State space model for sequence prediction
Each model has a standalone trainer and a UnifiedTrainable adapter for the hyperopt pipeline.
Infrastructure
- Git: Gitea at
git.fxhnt.ai(Tailscale-only), Scaleway DEV1-S - Observability: OpenTelemetry OTLP (env
OTEL_EXPORTER_OTLP_ENDPOINT) - Database: PostgreSQL with SQLx offline mode for CI
