check / check (push) Waiting to run
The script/ builds pass a new CACHEBUST build argument on every run in place of --no-cache, which also emptied Go's build cache mount. Every Dockerfile stage declares ARG CACHEBUST first, so every RUN step still reruns on an unchanged tree. The canonical Go Dockerfile mounts only Go's build cache, on the steps that compile, so compiled packages survive between check builds; both go test runs carry -count=1, so no test result is reused. golangci-lint's own cache and the module cache are not kept. A repository re-vendors the scripts and adds the ARG lines in one commit: a stage without the line is served from cache with no warning. Unverified: not yet tried on the shared CI runner. Model: opus-5-5
