check / check (push) Waiting to run
script/lint and script/test build their Dockerfile phase with --output type=cacheonly in place of a tag. The phase still runs uncached and a failing step still fails the build, but no image is written: nothing used those images, and writing one out took about 16 seconds of a Go repository's test build. script/cibuild and script/docker keep their tags. REPO_POLICIES.md, both checklists and the README now say the gate builds write no image. Model: opus-5-5

# script/lint: run the linter. Linting is a phase of the Dockerfile and
|
|
# this builds that phase alone; the linter is never installed or run on
|
|
# a developer host, where a shared result cache and a host-global lock
|
|
# make its answer untrustworthy.
|
|
#
|
|
# The phase is not the last stage in the file, so it is built only when
|
|
# --target names it. --no-cache because a cached lint layer is a lint
|
|
# that did not run. --output type=cacheonly writes no image, since
|
|
# nothing uses one.
