# Pull Request Guide Use the GitHub PR template provided in `.github/pull_request_template.md`. Key items to verify before submitting: 1. Align with the active milestone in `docs/improvement/RELEASE_PLAN_v1.md` and reference relevant ADRs. 2. Add or update tests for new behavior and ensure they pass locally. 3. Run mypy for changed modules and ruff/markdownlint for style. 4. Update README/docs when public behavior changes. 5. Note breaking changes with migration notes; update CHANGELOG when applicable. This page is a convenience summary; the authoritative checklist lives in the PR template.
