Extract 9 new sub-crates from the ml monolith to enable parallel compilation across the workspace: New crates (this commit): - ml-features (282 tests): feature engineering, 21 modules - ml-labeling (45 tests): triple barrier, meta-labeling, fractional diff - ml-ensemble (116 tests): ensemble coordination, voting, confidence - ml-hyperopt (47 tests): core PSO/TPE optimizer, parameter space - ml-checkpoint (41 tests): checkpoint persistence, compression, signing - ml-regime (68 tests): CUSUM, Bayesian changepoint, regime classification - ml-data-validation (67 tests): FDR correction, CPCV, data quality - ml-risk (33 tests): neural VaR, Kelly criterion, circuit breakers - ml-validation (43 tests): statistical validation, walk-forward, DSR Extended existing crates: - ml-dqn: added evaluation/ (backtesting engine, metrics, reports) and checkpoint implementation - ml-supervised: added checkpoint implementations - ml-core: added shared types needed by new sub-crates Pattern: each module in ml/ becomes a thin facade (pub use subcrate::*) with bridge modules staying in ml for cross-model adapter code. Dead code deleted (~7K lines): - 13 undeclared files in microstructure/ (never compiled) - 7 undeclared files + tests/ in risk/ (never compiled) - parquet_io, cache_service, cache_storage, minio_integration (unused) - extraction_wave_d_impl.rs (bare fn outside impl block) All 2,746 sub-crate tests + 951 ml tests pass. Full workspace builds clean. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

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
