check / check (push) Successful in 7m45s
Both scripts pass a new CHECK_EPOCH, which the Dockerfile's make fmt-check, make lint and make test steps name in their commands. On an unchanged tree Docker used to serve those steps from its build cache, so a run could pass without checking anything. The script/bootstrap steps stay cached. A plain docker build . still works, as upaas builds the image that way: it leaves CHECK_EPOCH empty and reuses the check steps only for an identical build context. Model: opus-5-5
