Accomplishments

1. backend/config_loader.py Refactored

   • Implemented YAML parsing using PyYAML
   • Enforced D-06 load order: System Env Vars > config/backend.yaml > config/secrets.yaml > Defaults
   • Added robust validation for required fields (JWT_SECRET_KEY, primary_ai_provider)
   • Masked sensitive values in logs

2. backend/config_manager.py Updated

   • Refactored to handle YAML file operations (read_config, update_config)
   • Removed legacy .env file manipulation logic

3. backend/main.py Updated

   • Switched from direct os.environ access to the centralized get_config() dict
   • Removed load_dotenv() and inventory.env references

4. backend/entrypoint.sh Updated

   • Updated to document the new YAML configuration structure
   • Added safety checks for the existence of backend.yaml

5. Additional Backend Files Cleaned Up

   • Refactored backend/ai_vision.py, backend/check_models.py, backend/ai/gemini.py, and backend/ai/claude.py to use config_loader
   • Completely removed python-dotenv dependency from backend

Technical Details

• Load Order (D-06): Env Vars override YAML, YAML overrides Defaults.
• Deprecation (D-04): inventory.env is no longer used by the backend application logic.
• Security: Sensitive configuration values are masked in application logs to prevent data leaks.

---

Verification

• All updated Python files passed py_compile checks
• No load_dotenv() or inventory.env references remain in backend code
• Configuration loading logs which source was used for each value
• Environment variables correctly override YAML values in config_loader.py
