Codebase audit identified 23 findings across 4 dimensions (production safety, code health, deployment readiness, test quality). This commit fixes all of them. Broker execution layer (was entirely stubbed): - Real IBKR TWS client via ibapi crate (950+ lines, feature-gated) - ICMarkets ctrader-openapi now always-on (removed feature flag) - Real broker routing with health monitoring and exponential backoff reconnect - Validated against live IB Gateway Docker (6/6 connectivity tests pass) Deployment blockers: - Fixed 6 broken Dockerfiles (removed COPY foxhunt-deploy) - Created foxhunt K8s namespace, secret templates, migration job - Added liveness probes to all 7 K8s services - IB Gateway manifest (ghcr.io/gnzsnz/ib-gateway:stable) - IBKR credentials in Scaleway Secret Manager via Terragrunt - Fixed port collisions and mismatches across services Production safety (9 critical + 6 high/medium fixes): - Asset-class-specific VaR volatility (not flat 2%) - Real parametric VaR with z-score 95th percentile - Kyle's lambda regression (100-bar rolling window) - Per-feature running statistics from historical data - VWAP-based slippage reference, regime duration tracking - Real Databento JSON parsing for OHLCV/Trade/Quote Code health: - Removed #![allow(dead_code)] from ml, data, config - Fixed log:: → tracing:: in 4 production files - Removed dead workspace deps (ratatui, crossterm) Verified: cargo check --workspace (0 errors), trading_engine 330 tests pass.

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
