Eliminate ~4,260 clippy deny-level errors that blocked workspace-wide clippy runs. Errors cascaded: upstream crate failures (ctrader-openapi, risk-data) hid thousands of downstream errors in ml, tli, backtesting. Key changes: - ctrader-openapi: fix shadow_unrelated/shadow_reuse (renamed vars) - risk-data/risk: replace non-ASCII em dashes with ASCII equivalents - tli: allow deny lints on prost-generated proto code, fix shadows - trading_engine: fix let_underscore_must_use, wildcard matches, shadows - broker_gateway_service: allow dead_code on unused redis_client field - ml (4030 errors): remove local deny overrides for unwrap/expect/indexing (workspace warn level sufficient), add crate-level allows for non-safety mass-violation lints (non_ascii_literal, shadow_*, str_to_string, etc.), batch-fix em dashes, unseparated literal suffixes, format_push_string, wildcard matches, impl_trait_in_params, mutex_atomic, and more - backtesting: replace unwrap() on first()/last() with match destructure - tests: simplify loop-that-never-loops, fix mutex unwrap 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
