check / check (push) Waiting to run
Re-vendors REPO_POLICIES.md and script/cibuild, docker, lint and test from sneak/prompts at 0653579, on sneak's ruling in sneak/prompts#130. In the Dockerfile's lint, test and builder stages, the system-package install and the module download now come before ARG CACHEBUST, so Docker keeps those layers until the base image, the install line, go.mod or go.sum changes. golangci-lint run also mounts golangci-lint's cache. Every step that lints, tests or compiles still runs on every check build, and go test keeps -count=1 and -race. README and TODO.md say the same. Model: opus-5-5
