- Introduced runtime bootstrap helpers in `mjr_am_backend.features.runtime` for dependency initialization.
- Implemented `apply_startup_settings` to handle various startup configurations.
- Added search request normalization helpers in `mjr_am_backend.features.search` including `SearchRequestContext` and `parse_search_request` for better query handling.
- Created audit logging helpers in `mjr_am_backend.routes.core.audit_log` for state-changing route handlers.
- Developed a quality gate script in `scripts/run_quality_gate.py` to enforce code quality checks.
- Added comprehensive tests for audit routes, scan consistency, vendor routes, and code quality metrics.
- Organized and grouped import statements for better readability in health.py, metadata.py, releases.py, scan.py, search.py, version.py, viewer.py, and registry.py.
- Updated type hints to use the new union syntax (e.g., str | None) for better clarity in scan.py, settings.py, tool_detect.py, and result.py.
- Enhanced the handling of optional types in various functions to ensure more robust type checking.
- Removed unnecessary blank lines and improved formatting for consistency.
- Adjusted the logic in several test files to ensure compatibility with the updated import structure and type hints. (See <attachments> above for file contents. You may not need to search or read the file again.)
