Status: still outstanding; keeping this issue open. No kube-flannel.yaml, flannel-overlay.yaml, or kube-proxy.yaml manifests are tracked in this repository. The minikube source at the commit linked in this issue downloads all three from vrapolinario/MinikubeWindowsContainers on its mutable main branch. Remaining work: establish the intended ownership/versioning of these manifests, track or pin them accordingly, and update the consuming minikube references. This assessment covers the source revision linked in the issue, not the current minikube branch.
