name: CI

# CI runs once per merge on `develop`, the trunk (AGENTS.md, "Workflow for every change"): the core
# team's pull requests are checked locally on the crates they touch and merged; a red trunk is
# fixed forward. `main` holds released code only (docs/releasing.md).
# Pull requests from forks (outside contributors) run the full gate, once the maintainer approves
# the run, so the review sees it; so do Dependabot's (.github/dependabot.yml), which nobody tests
# locally. The heavy job stays off pull requests.
