Genuinely isolated node (0 others running, 397GiB free, terminal start
state, read-only polling) still failed at 1770s = 29.5/30 min. Refutes
contention but consistent with INHERENTLY SLOW; batch 3-pass/6-fail-at-the-
mark is the classic marginal-timeout signature. 3 nodes reached Ready on the
same rack/subnet/metadata path, so metadata is not globally broken (:5248 up,
rack->region 301; a :5248 tcpdump was inconclusive -- window closed before
the fetch stage). Recommended test needs an operator decision (MAAS-wide
config): raise node_timeout, commission one node. Stopped live diagnosis per
the circuit-breaker.
CURRENT-STATE updated in this commit (GA-R1/C1).
