Session bookend (successor-landed): G12 dc1-authoring session disconnected mid-item-3 ...

Drop-state recorded, not delivered: dc1 vars + substrate root + lib-net dc1

assert the retired vr1-dc1 fail-loud arm -- capture in docs/audit/). G12 row
updated same-commit (GA-R1/C1). Working-tree authoring intentionally left

Importer harness 117/117; live dc1 dry-run preflight PASS (captures committed).

Fix committee doc: ASCII byte (em-dash in title) + CURRENT-STATE pointer (L10) ...

Prior commit 34c8770 pushed with a non-ASCII em-dash in the committee doc
title and a decoupled L10; both fixed here. Correct lint gate learned: repo-lint
exits 0 clean / 1 FAIL / 2 warn-only, so the right gate is exit != 1 (the
permanent legacy design-decisions WARN makes exit 2 the normal clean state) --
not the exit==0 I mis-used, and not the piped-tail that masked real exit-1 fails.

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.

Clean commissioning experiment: contention refuted; leading hypothesis = marginal 30-min timeout over slow nested I/O ...

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.

SEC-012 + SEC-013: ledger rows for the two credentials this deploy created (obligation was outstanding) ...

SEC-012: dedicated MAAS->libvirt service key. Held by a daemon on BOTH
controllers (MAAS dials the pod from the REGION, measured), authorizes a
libvirt-group user, so it can drive every inner node VM and the DC edge.
Rotation obligation + a SCOPE question: libvirt-group is broader than the
power verbs MAAS needs; tighter grant is the hardening candidate and is
Roosevelt-relevant (IPMI has the same power-only-vs-full-control question).
SEC-013: admin-scoped MAAS API key materialized to disk on the region;
surfaces include any maas-provider tfstate and a CLI profile. Verified by
format only, never printed. Tied to whether vr1-dc0-maas is retired.

node-vm console shipped (0/9/0 in-place); commissioning narrowed, UNRESOLVED; two of my own experiments disclosed as INVALID ...

Console added + log dir parameterized, but logs stay 0 bytes: firmware
writes to VGA, so serial alone does not make a PXE-booting node observable
-- correction queued (needs graphics + virsh screenshot, or a MAAS kernel
cmdline change). Solid: PXE + ephemeral handoff work; ephemeral OS boots
with working networking (leases + NTP to rack); no region/metadata traffic
seen; memory, image sync, DHCP and shape all ruled out. SEC-010 blocking
node->region is SUSPECTED but unreadable (rules lack counters).
INVALID EXPERIMENTS RECORDED: the 'single node alone' test was not alone
(5-6 nodes still up, proven by tcpdump), and the retry did not restart
MAAS's timer while I destroyed domains mid-run. Contention is therefore a
LIVE hypothesis again, not refuted. Stopped per the circuit-breaker rather
than iterate on contaminated evidence.
CURRENT-STATE updated in this commit (GA-R1/C1).
