Configuration Management

[hnaik]

Labels: infra, priority: medium

Description

Establish a consistent configuration system across all components.

Scope

• YAML-based config files with environment variable overrides.
• Typed config objects (Pydantic) with validation at load time.
• Hierarchical: global defaults → component-specific → run-specific overrides.
• Sensitive values (API keys for Databento, IBKR credentials) handled via environment variables or a secrets file excluded from version control.
• Config snapshots saved alongside backtest results for reproducibility.
