check / check (push) Failing after 4s
Linting and testing become the lint and test phases of the Dockerfile, and the build stage depends on both. Dockerfile.lint, CHECK_EPOCH and the tests that checked them are removed. Every docker build in script/ passes --no-cache, and script/cibuild runs script/bootstrap first. The image takes its version from the VERSION build arg or git describe, and still stamps the commit and its date from .git. The golangci-lint v2.14.0 findings are fixed in the code. The rules in CLAUDE.md move into AGENTS.md. IsDevVersion now counts "unknown", the version script/docker stamps outside a git checkout. Model: opus-5-5

Docker is required to develop this repo. Without it these do not work:
|
|
|
|
script/lint builds the lint phase of the Dockerfile, which runs
|
|
the linter as a build step in a digest-pinned
|
|
golangci-lint image
|
|
script/test builds the test phase of the Dockerfile
|
|
script/check runs script/test and script/lint
|
|
script/precommit runs script/check, so commits are blocked by the
|
|
pre-commit hook installed by script/setup
|
|
script/cibuild runs script/check and builds the image, which is
|
|
what CI runs
|
|
|
|
Install docker (and start the daemon, checking DOCKER_HOST and your
|
|
group membership), then re-run script/bootstrap. golangci-lint on PATH
|
|
is deliberately not a substitute: script/lint will not use it.
