Use the namespace returned by List.
List returns each namespace’s labels, and generateTestCase only reads the name and labels. CollectData then performs one Get for every eligible namespace. If a namespace is deleted between these calls, Get returns NotFound; CollectData returns nil, nil, err and discards the complete monitor result. Pass the listed namespace object to generateTestCase. No resourceVersion or fresh-read contract requires the additional Get.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Check the six standard PSA label keys, not the label count.
For this monitor’s syncer contract, the expected keys are enforce, enforce-version, audit, audit-version, warn, and warn-version. Kubernetes accepts arbitrary qualified label suffixes under pod-security.kubernetes.io/, so six unrelated keys can satisfy the count. The namespace then avoids the missing-label failure; without sync=false, it can also be treated as unmanaged. Check each required key and use !hasAllPSALabels in the failure condition instead of numberOfPSALabels < 6.

Use a bounded context for Kubernetes API calls.
The Ginkgo monitor run passes a cancel-only context to m.Stop, and the registry waits for every CollectData goroutine. This monitor passes that context unchanged to List and Get. The client configuration does not set rest.Config.Timeout; client-go treats zero as no request timeout. If the API server is unreachable, collection can therefore wait without a deadline. Create a bounded child context before List, and pass it to generateTestCase for its Get calls.
