Subject: [PATCH 7/8] feat: architectural overhaul for performance and
stability
- Optimize Python backend:
- Implement persistent SQLite connection with WAL mode.
- Implement batch log insertion.
- Optimize WMI queries (column selection).
- Fix race condition in process monitoring (PID reuse handling).
- Add type hints and docstrings (mypy strict).
- Optimize Flutter frontend:
- Implement `LineSplitter` for robust stdout processing.
- Optimize `DatabaseService` (pagination, stream-based UI updates).
- Reduce polling frequency (10s backup).
- Add error handling and logging.
- Add comprehensive testing:
- Python: `pytest` with >90% coverage (mocking WMI/DB).
- Flutter: `widget_test` with mocks.
- configuration:
- Add `pyproject.toml`, `.pre-commit-config.yaml`, `requirements.txt`.

Subject: [PATCH 8/8] feat: architectural overhaul for performance and
stability
- Optimize Python backend:
- Implement persistent SQLite connection with WAL mode and `threading.Lock`.
- Implement batch log insertion.
- Optimize WMI queries (column selection).
- Fix race condition in process monitoring (PID reuse handling).
- Add type hints and docstrings (mypy strict).
- Optimize Flutter frontend:
- Implement `LineSplitter` for robust stdout processing.
- Optimize `DatabaseService` (pagination, stream-based UI updates).
- Reduce polling frequency (10s backup).
- Add error handling and logging.
- Add comprehensive testing:
- Python: `pytest` with >90% coverage (mocking WMI/DB).
- Flutter: `widget_test` with mocks.
- Configuration:
- Add `pyproject.toml`, `.pre-commit-config.yaml`, `requirements.txt`.
