🚥 Pre-merge checks | ✅ 10 | ❌ 2

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Microshift Test Compatibility	⚠️ Warning	PR adds Ginkgo tests that reference MicroShift-unavailable APIs (ImageRegistry operator, ClusterOperator) without protection tags.	Add [apigroup:imageregistry.operator.openshift.io] and [apigroup:config.openshift.io] tags to test names in test/e2e/v2/tests/hosted_cluster_image_registry_test.go, or add [Skipped:MicroShift] if intentionally unsupported.
Single Node Openshift (Sno) Test Compatibility	⚠️ Warning	Multiple new e2e Ginkgo tests added (autoscaling_test.go, karpenter_test.go, nodepool_rolling_upgrade_test.go, etc.) make multi-node/HA assumptions without SNO compatibility protections.	Add [Skipped:SingleReplicaTopology] labels to tests assuming multiple nodes, or guard with exutil.IsSingleNode() checks. Tests like autoscaling, rolling-upgrade, and karpenter tests require multiple nodes.

✅ Passed checks (10 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title clearly describes the PR's purpose: testing ARC runner infrastructure with a trivial whitespace change, which aligns with the stated objectives.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	PR contains no Ginkgo tests. All tests use standard Go testing package with Test* functions, not Ginkgo framework. No It(), Describe(), Context(), or When() test blocks found.
Test Structure And Quality	✅ Passed	PR contains only a whitespace change to hack/github-actions-runner/README.md with no Ginkgo test code, so the test structure and quality check is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	PR modifies only hack/github-actions-runner/README.md (whitespace/formatting), not deployment manifests, operator code, or controllers. Check is not applicable to documentation-only changes.
Ote Binary Stdout Contract	✅ Passed	PR's primary change is hack/github-actions-runner/README.md, a documentation file. OTE Binary Stdout Contract applies only to executable code's process-level functions, not documentation.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR only modifies hack/github-actions-runner/README.md with whitespace. No new Ginkgo e2e tests were added, so IPv6/disconnected network check is not applicable.

Test Failure Analysis

Error

1: CT1 Title does not start with one of fix, feat, chore, docs, style, refactor, perf, test, revert, ci, build: "NO-JIRA: test ARC runner infrastructure"
make: *** [Makefile:599: run-gitlint] Error 1

Summary

The gitlint check failed because the commit title NO-JIRA: test ARC runner infrastructure does not follow the Conventional Commits format required by the repository's .gitlint configuration. The title must begin with one of the allowed type prefixes (fix, feat, chore, docs, style, refactor, perf, test, revert, ci, build) followed by a colon, but it begins with NO-JIRA: instead.

Root Cause

The repository enforces Conventional Commits via gitlint's built-in contrib-title-conventional-commits rule (configured in .gitlint at the repo root). This rule requires commit titles to match the pattern <type>[optional scope]: <description>, where <type> must be one of: fix, feat, chore, docs, style, refactor, perf, test, revert, ci, build.

The commit message on this PR is:

NO-JIRA: test ARC runner infrastructure

The prefix NO-JIRA: is not a recognized conventional commit type. The CT1 error code is gitlint's "Conventional commit Title" rule violation, confirming the title parsing failed at the very first token.

This is an intentional test PR ("Add trivial whitespace change to verify self-hosted runners are processing jobs after SCC fix") where the commit message was written to match the older Jira-prefix convention rather than the Conventional Commits standard the repo now enforces.

Recommendations

1. Amend the commit message to use a valid Conventional Commits prefix. For this infrastructure-test PR, a suitable rewrite would be:

   ci: test ARC runner infrastructure
   

   or:

   chore: test ARC runner infrastructure
   

2. If the PR is purely for infrastructure validation and will not be merged, the failure can be ignored — the gitlint check passing is not required for the ARC runner infrastructure to be considered validated. The fact that the job ran and produced the expected linting output confirms the self-hosted ARC runners are operational.
