# SwiftLint, as `just lint` runs it: over Grain and GrainTests with the
# repository's .swiftlint.yml, on pushes to main and pulls into it. An
# error fails the step; warnings are reported and pass, as they do locally.
#
# Xcode does not run on the Linux runner, so the build and the tests are
# not here: see format.yml.
#
# SwiftLint is its Linux release, pinned by version and SHA-256, so a
# release's new rules land on purpose rather than with an unrelated push.
# Its own image will not do, for format.yml's reason: its entrypoint is
# swiftlint. The release's `swiftlint-static` is the one that runs on a
# bare Debian: `swiftlint` wants libxml2 and the Swift runtime. The
# download is kept between runs.
