+BreakPilot Secret Store Module
+
+This module provides a unified interface for accessing secrets from:
+1. HashiCorp Vault (production)
+2. Environment variables (development fallback)
+3. Docker secrets (containerized environments)
+
+Security Architecture:
+- Vault is the primary secrets store in production
+- Environment variables serve as fallback for development
+- No secrets are ever hardcoded in the application code
+
+Note: Renamed from 'secrets' to 'secret_store' to avoid conflict
+with Python's built-in secrets module.
