Diagnostic committee (4 reviewers) refutes marginal-timeout 4/4; MTU exonerated by measurement ...

Committee synthesis: docs/audit/commissioning-committee-20260720.md. Consensus:
30-min silence = a HANG not slow progress, so raising node_timeout is the wrong
knob; the proposed one-node test was confounded (timeout + concurrency changed
together). Process errors caught: measured rack not region, tcpdump doubly
mis-scoped (port + window), enlistment paradox resolved (MAAS logs script
COMPLETION so a hung commissioning-only script = identical silence). Pivotal
zero-cost reads: metal-admin MAAS VLAN MTU = 1500 -> guest never jumbo -> MTU
branch EXONERATED; region ample RAM, Temporal quiet at rest (175k wedge errors
were pre-restart). Live causes now: region Temporal starvation during a run,
and a commissioning-only script hang on nested-virt hardware. Decisive gated
test: one commission + console=ttyS0 kernel opt + full-window lease-IP capture
on virbr2+enp1s0.
CURRENT-STATE updated in this commit (GA-R1/C1).
