REPO_POLICIES.md, script/cibuild, script/docker, script/lint and script/test are their copies at that commit. In every Dockerfile stage the system package install and the Go module download now come before ARG CACHEBUST, so check builds keep those layers until the base image, the install line, go.mod or go.sum change. golangci-lint run also mounts golangci-lint's cache. The test phase and the build stage install their packages with apt-get and apk directly, as REPO_POLICIES.md now has them do, instead of through script/bootstrap --cgo. The test phase keeps Debian's recommended packages, which bring libheif's AVIF encoder that the tests use. Model: opus-5-5
