🚥 Pre-merge checks | ✅ 15

✅ Passed checks (15 passed)

Check name	Status	Explanation
Title check	✅ Passed	The title clearly states the main API change by adding the configurationSource selector to ClusterMonitoring.
Description check	✅ Passed	The description matches the change by explaining the selectable config source and the CRD default.
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	The added test titles are static, descriptive strings with no dynamic suffixes, timestamps, UUIDs, or other run-specific values.
Test Structure And Quality	✅ Passed	The added YAML validation cases are isolated, one behavior per test, and match existing schema-test patterns; no cluster ops, waits, or cleanup gaps.
Microshift Test Compatibility	✅ Passed	Added tests are envtest YAML validation cases, not Ginkgo e2e specs, and no MicroShift-specific unsupported API usage was introduced.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	Added tests only validate ClusterMonitoring CRD schema values/errors; they don’t schedule pods, inspect topology, or assume multi-node behavior.
Topology-Aware Scheduling Compatibility	✅ Passed	PR only adds configurationSource API/CRD validation and tests; no deployment manifests, controllers, node selectors, affinity, or replica logic changed.
Ote Binary Stdout Contract	✅ Passed	PR only changes API/CRD/schema files; no main/init/TestMain/BeforeSuite code or stdout logging/prints appear in changed files.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	No new Ginkgo e2e tests were added; the new ClusterMonitoring YAML validation cases only set configurationSource and contain no IPv4 or external connectivity assumptions.
No-Weak-Crypto	✅ Passed	Touched files only add configurationSource schema/tests; exact scans found no MD5/SHA1/DES/RC4/3DES/Blowfish/ECB or constant-time compare usage.
Container-Privileges	✅ Passed	Changed files are API/CRD/tests only; none contain privileged, host* namespace, SYS_ADMIN, root, or allowPrivilegeEscalation settings.
No-Sensitive-Data-In-Logs	✅ Passed	The PR only adds API schema/tests; I found no new logging statements or sensitive-data outputs in the touched files.
