The nightly upgrade chain fails a preflight Job and raises K8sUpgradeBlocked
every night for the 1.36 target, even though the block is unactionable: no
kyverno/ESO release supports 1.36 yet and gpu-operator is deliberately pinned
(NVIDIA driver/Ubuntu coupling). Viktor asked to teach the checker to tell
'we can fix this' apart from 'nothing to do but wait', and stop the nightly
Failed-Job + alert noise for the latter.
This documents the design: classify each blocker as actionable / waiting-
upstream / pinned, keep the alert only for actionable, quiet the held case to
the nightly report, and make deliberate gate decisions Complete cleanly.
