🎯 System Overview

Foxhunt is a high-frequency trading system built in Rust with ML/AI-powered decision making. It uses a microservices architecture with gRPC communication, PostgreSQL for persistence, and advanced ML models (MAMBA-2, DQN, PPO, TFT, TLOB).

Core Principle: REUSE existing infrastructure. DO NOT rebuild components.

Component Responsibilities

API Gateway: Single entry point, JWT + MFA auth, rate limiting, audit logging, routing for 37 gRPC methods.
Trading Agent Service: Orchestrates trading decisions (universe/asset selection, portfolio allocation) and sends orders to the Trading Service. Performance: <5s end-to-end decision loop.
Trading Service: Executes orders, manages positions, and tracks PnL.
Backtesting Service: Tests strategies using real DBN data with high-speed loading (0.70ms) and automatic price anomaly correction.
ML Training Service: Manages the model training pipeline, feature engineering, and hyperparameter tuning (Optuna). GPU-accelerated (RTX 3050 Ti) for all models, including MAMBA-2.

Service Credentials

PostgreSQL (TimescaleDB): postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt
Redis: redis://localhost:6379
Vault: http://localhost:8200 (Token: foxhunt-dev-root)

Service Ports

Service	gRPC	Health	Metrics
API Gateway	50051	8080	9091
Trading Service	50052	8081	9092
Backtesting Service	50053	8082	9093
ML Training Service	50054	8095	9094

GPU/CUDA Configuration

RTX 3050 Ti - CUDA enabled for ML training and inference.
Environment: CUDA_HOME, LD_LIBRARY_PATH, and PATH are pre-configured.
Verification: nvidia-smi and nvcc --version.
Usage: let device = Device::cuda_if_available(0)?; (auto-fallback to CPU).

🚫 Critical Architectural Rules

Configuration Management: ONLY the config crate accesses Vault. All services use config::ConfigManager.
TLI Architecture: The TLI is a PURE CLIENT. It has NO server components and connects ONLY to the API Gateway.
Service Boundaries: All inter-service communication is via gRPC. The Trading Agent decides, and the Trading Service executes.
Error Handling: Use CommonError factory methods (CommonError::config, CommonError::network, etc.).
Port Validation: Services must fail-fast on port conflicts. Use lsof -i :<port> to debug.

- Validate +25-50% Sharpe improvement hypothesis before real capital deployment
Production Validation (1-2 weeks paper trading):
- Monitor 24/7 with Grafana dashboards (real-time regime transitions)
- Track key metrics:
  - Regime transitions: 5-10 per day (alert if >50/hour flip-flopping)
  - Position sizing: 0.2x-1.5x range validation (regime-adaptive)
  - Stop-loss adjustments: 1.5x-4.0x ATR validation (dynamic)
  - Risk budget utilization: <80% target (safety margin)
  - Regime-conditioned Sharpe: >1.5 target per regime
- Adjust thresholds based on real trading data
- Validate rollback procedures (3 levels: feature-only, database, full)
Quality & Security (Ongoing):
- Increase test coverage from 47% to >60%
- Add encryption to TLI token storage
- Fix E2E test proto schema mismatches (est. 2 hours)
- Implement automated Wave D feature validation (every 5 min)
- Set up operational playbooks for common issues (flip-flopping, false positives, NaN/Inf)

🔒 Security & Best Practices

Development: Use .env files (gitignored), no hardcoded credentials.
Production: Use Vault for all secrets, enable MFA, rotate JWT secrets, use TLS for gRPC, and enable audit logging.
Anti-Workaround Protocol: Fix root causes, do not use stubs or placeholders, and reuse existing infrastructure.
