Make changes to source code 3. Test with `python _pipeline.py` from `sources/` folder 4. Run tests: `pytest tests/` 5. Lint: `make lint-code` 6. Format: `make format-lint` ## PR requirements 1. Must pass linting (mypy, flake8) and formatting (black) 2. Google-style docstrings in all relevant sections 3. Code must be typed 4. Source folder must contain `requirements.txt` with versioned dlt dependency 5. Use relative imports in source modules 6. Tests must pass on duckdb and postgres 7. Add or update tests for significant changes ## Dependencies - Add source-specific deps with `uv add --group ` - Also add to `requirements.txt` in the source folder - dlt dependency in requirements.txt: `dlt>=X.Y.Z,` sections in secrets.toml
