# Formatting and lints, as `just lint` checks the Rust, on every branch
# pushed; test.yml runs the tests. On a pull, that a change to the client
# comes with a change file (harness/changes.sh).
#
# The image is the Rust `just lint` runs locally, so a newer release's new
# lints land on purpose. The build and the toolchain's components are kept
# between runs, so a push lints only what it changed.
