The three KubeVirt VM conformance tests (vm-lifecycle, vm-default-deny,
vm-data-survival) carried comments asserting the ALPHA `ImageVolume` feature
gate is DISABLED "on this k3s v1.31 cluster" and that the apiserver therefore
prunes the container-disk `image` volume, breaking the containerDisk boot path.
The cluster was upgraded v1.31 -> v1.36.4. Revalidated the gate live:
- kubernetes_feature_enabled{name="ImageVolume"} = 1 (enabled by default;
stage="" — no longer ALPHA)
- a server-side `kubectl apply --dry-run=server` of a Pod with an `image`
volume RETAINS the volume + mount instead of pruning them.
So the old premise is stale: containerDisk roots would boot on 1.36.4. The
tests never asserted the gate state and never used containerDisk — they boot
from CDI DataVolume roots, which remains the correct choice because it is the
spec-required, rebuild-surviving disk model (docs/06, R-STATE-01); an ephemeral
containerDisk could never satisfy data-survival. Test logic is therefore
unchanged; only the explanatory comments are corrected (v1.31 -> v1.36.4, and
the "containerDisk is broken here" rationale marked stale with the live
evidence).
Merge gate: PASS (lint, l0, render-golden, l1 green).
