It wires a Make target, downloads or builds required binaries, verifies checksums, updates development tools, documents usage, and extends ShellCheck workflow coverage. ChangesEnvtest sideloading
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The test setup now downloads and executes a shared script from the default main branch, so an unexpected change to that source could run with developer or CI permissions and affect the local envtest cache. The impact is limited to development and test workflows, and downloaded Kubernetes and etcd binaries are checksum-verified; the PR is mergeable with explicit owner awareness or follow-up to pin and authenticate the script.

Hoist hack/envtest-sideload.sh out of apiserver-kit, artifact-conduit and solution-arsenal into scripts/, exposed as the envtest-binaries-sideload target. solution-arsenal's copy is canonical: it is a strict superset with macOS support, .zip etcd handling, a portable sha256 check and two bug fixes the other two never received. Unlike repo-settings, the script is cached in $(LOCALBIN) rather than piped straight to bash: it is a prerequisite of `make test`, which must not gain a hard network dependency once the envtest cache is warm. DEV_KIT_VERSION is part of the filename, so Make's own file-target check does the invalidation. Move the DEV_KIT_VERSION fallback to the top of common.mk — ENVTEST_SIDELOAD is the first use of it in a target name, which is expanded at parse time. Add git and unzip to the dev shell for the macOS source-build path, and widen test-actions.yml to shellcheck scripts/ — dev-kit has no Makefile, so CI is the only lint path once the script leaves the consumers.

) ## What Give dev-kit's own workflows the token-permissions hygiene it asks of consumers, extend the action-pin check to `.github/actions/`, and document `setup-nix` for new repos. Part of opendefensecloud/artifact-conduit#441 ## Why Three of seven workflows had no top-level `permissions:` — the same Token-Permissions gap that was closed in solution-arsenal (17/17) and artifact-conduit (16/16) but never here. It matters more in dev-kit: `docs/NEW_REPO.md` tells people to copy these workflows, so the gap propagates to every new repo. The pin check had a matching blind spot. Since #30, dev-kit ships an action containing two third-party SHA pins, and both the path filter and the grep root stopped at `.github/workflows/` — so the repo that defines the pin standard did not apply it to itself. ## Testing - Ran the widened check against the tree: passes, and now covers `.github/actions/setup-nix/action.yml`. - `actionlint` clean; all workflow and action YAML parses. ## Notes for reviewers - **Latent bug fixed in passing:** the check used `grep -rE`, and `-r` prefixes each output line with its filename, so the next filter — `grep -vE '^\s+(- )?uses: \./'`, the local-action exclusion — could never match. Any `uses: ./` would have been reported as unpinned. Harmless so far (dev-kit references no local actions), but widening the scan made it worth correcting. Solar's copy already uses `-rhE`; this aligns them. - `issues-add-to-project` gets job-level `permissions: {}` — it authenticates with `ADD_TO_PROJECT_PAT`, so `GITHUB_TOKEN` needs no scopes. `issues-add-labels` keeps its existing job-level `issues: write`. Placement matches Solar's convention. - `NEW_REPO.md`: adds the Cachix org secrets to §4, `update-action-pins.yml` to the §5 workflow table (also missing), and a "Nix-based CI" subsection with the `setup-nix` caller snippet and the fork-PR read-only note. - `README.md`: the `setup-nix` example said `# v2.1.0`, which is the envtest-sideload release (#29) — cut before #30 merged, so it does not contain the action. Now `# <tag>`. - No Renovate config added — dev-kit is the only repo without one, but the reason is unknown and that is a separate decision. ## Checklist - [ ] Tests added/updated — n/a, no shell script to test - [x] No breaking changes (or upgrade path documented above) - [x] Readable commit history (squashed and cleaned up as desired) - [ ] AI code review considered and comments resolved <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Security** - Strengthened automation permissions by limiting workflows to only the access they require. - **Maintenance** - Expanded action pin checks to include actions throughout the automation configuration. - Monitors changes to shared actions as well as workflow files. - **Documentation** - Updated setup guidance for pinned actions. - Added instructions for Nix-based CI and documented required authentication secrets. - Documented the action-pin maintenance workflow. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

What
Provide envtest binary sideloading from dev-kit, replacing the copy that currently exists three times over in apiserver-kit, artifact-conduit and solution-arsenal.
Refs opendefensecloud/odd-internal#59
Why
setup-envtest's release index lags upstream Kubernetes releases, so a Renovate bump ofENVTEST_K8S_VERSIONbreaksmake testuntil controller-tools catches up (see opendefensecloud/solution-arsenal#556; the upstream issue is closed-as-not-planned). The workaround — populatesetup-envtest's cache directly fromdl.k8s.ioand the etcd GitHub releases — was landed three separate times, and macOS support was then added to only one of them.The three copies have since diverged, and the two older ones carry bugs the newest already fixed — a missing
tr -d '"'on the yq output lets quotes leak into the constructed URLs, among others. solution-arsenal's version is a strict superset, so it is taken verbatim here and the extraction fixes the other two repos as a side effect.Testing
Both platforms exercised by running the real script, not just the Make wiring.

This is the only path that reaches the darwin-only branches, so it also covers the etcd.zipextraction and theshasum -a 256fallback.shellcheckclean onscripts/envtest-sideload.shandscripts/repo-settings.sh.Notes for reviewers
No consumer can use this until it is merged and tagged, because the target fetches the script at
$(DEV_KIT_VERSION). The last consumer PR carries theCloses.curl | bash.repo-settingsstreams its script on every invocation, which is fine for something run rarely, but this target is a prerequisite ofmake testand streaming would make every test run require network. Instead the script is downloaded once into$(LOCALBIN)withDEV_KIT_VERSIONembedded in the filename, so Make's own file-target check does the cache invalidation with no sentinel file or staleness logic.| $(LOCALBIN)is order-only and this is load-bearing. A directory's mtime bumps on every entry rename inside it, including themvin this very recipe, so a normal prerequisite would re-download on every singlemake test.-o $@.downloadthenmv.curl --failleaves no file on a 404 or DNS failure, but a mid-transfer drop does leave a truncated one, and there is no.DELETE_ON_ERROR:anywhere here — Make would keep it and treat it as built, after which a truncated script can exit 0 and the failure surfaces much later as an emptyKUBEBUILDER_ASSETSinside ginkgo.ifndef DEV_KIT_VERSIONfallback moved to the top ofcommon.mk.ENVTEST_SIDELOADis the first use of that variable in a target name, which is expanded at parse time; every existing use is inside a recipe and therefore deferred. Left at the bottom, the standalone case would yieldbin/envtest-sideload-.shand a.../dev-kit//scripts/...URL.ENVTEST_K8S_VERSIONis deliberately not defaulted here. Renovate's:k8spreset matches it per repo and groups the bump with that repo'sk8s.io/*gomod updates in a single PR, which is the coupling that makes a K8s bump not breakmake test. Centralizing it would break that matching, and dev-kit has norenovate.jsonto pick it up. Consumers also declare it after-include common.mk, so a?=here would silently win over their pin.gitandunzipadded to the dev shell for the darwin path — etcd ships.ziprather than.tar.gzfor macOS, and the source build shallow-clones the Kubernetes repo.test-actions.ymlwidened to shellcheckscripts/. Otherwise the script has no lint coverage anywhere: all three consumers lint it today viamake lint, and dev-kit has no rootMakefileto runmake shellcheckfrom.Checklist
