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