check / check (push) Waiting to run
Takes .golangci.yml, .dockerignore, .gitignore, .editorconfig, the workflow and REPO_POLICIES.md from sneak/prompts dd4027b, keeping this repository's own entries after the shared content. Lint (golangci-lint v2.14.0) and test become Dockerfile phases that script/lint and script/test build alone and uncached; the image build depends on both, and script/cibuild bootstraps, runs script/check, then builds the image. The agent guidance file moves to AGENTS.md. The Go code is fixed for what the new configuration finds; reads that iterate rows now also report an iteration error. Model: opus-5-5
