# script/lint: run the linters. eslint and prettier are never run against
# the working tree from here: linting runs via docker only, one way,
# everywhere — script/lint builds Dockerfile.lint, which COPYs the repo into
# the pinned node image and runs the linters as build steps. That works even
# when the docker daemon is remote and bind mounts are impossible.
#
# LINT_EPOCH is passed on every invocation because no lint cache is wanted:
# on an unchanged tree Docker would otherwise serve the linter layers, having
# linted nothing, and still exit 0. Dockerfile.lint refuses to build without
# the argument, so no path to a lint result can quietly come from cache.
#
# Nothing that runs inside a container may call this script; see the header
# of Dockerfile.
