The tenant Kubernetes suites fail the node-Ready budget with zero Nodes registered, and the time is lost inside the guest between the worker VMI reaching Running and Talos requesting its apid certificate. Nothing collected today covers that window: the existing in-guest capture drives talosctl, so it needs the very apid the worker never reached, and on the management side there is neither a Node nor a certificate request to read. Turn on the guest console log for the suite's node group and collect each virt-launcher's guest-console-log container from the management cluster. Reads start at the beginning of the stream rather than tailing it, so a guest that repaints its console cannot push the boot output out of the window; every read is bounded, and the walk stops at a cap that records both counts, so the collector cannot become the unbounded term in a failure path that already runs several others under one deadline. A read that returns no console is not filed as a quiet guest. Three outcomes get three labels, because only one of them says anything about the guest: the read failed and returned nothing, the read succeeded and returned nothing, or it broke off part way. Each read's stderr is kept beside the capture rather than inside it, since kubectl's own "container is not valid for pod" would otherwise fill the file and a console that never started would read as one that had spoken. That case is the headline one here, so the Pod state and events that explain it are collected alongside, once for the whole selector. Enabling the console overrides a cluster-wide setting the platform holds for an open upstream defect, so the run is also an experiment, and its own failure mode is the one that hides best: the container wedges virt-launcher in Init, no worker boots, and the suite reports "fewer than 2 tenant nodes Ready" -- the same sentence the failure under study produces. Read as the known signature, the experiment's answer would be filed as the flake it was meant to explain. So the failure path names that case first, before any other diagnostic, and only when it is true. The passing path checks separately that the container attached at all, and reports the ratio it saw rather than a bare success, since the check is deliberately satisfied by any one Pod. It keeps three outcomes apart too: a read that did not answer, a selector that matched no Pod, and Pods that matched and carry nothing. It reads the Pod name alongside the container names so the last two cannot collapse, and both container lists so a future move of the container cannot fail a run over a diagnostic. It runs last, after everything the suite exists to prove, because a debugging aid must not preempt the assertions that cover the cluster. The capture runs before the talosctl one because it is the only of the two that can describe a worker which never reached apid, the shape this failure keeps taking. kubectl reports a warning and an empty result alike, on stderr with a zero status, so the exit status decides which artifact its output lands in.
