# rk integrate runs this project's pre-integrate suite as
# `pre-commit run --hook-stage manual --all-files`. Assign to the manual
# stage every check that must pass before work reaches the trunk, and have
# continuous integration invoke the same stages: a check that runs on one
# side of the boundary alone guards one side alone.
