RULING (GA-R5), 2026-07-27. Question as presented: "The node-side half of bullet 5. Nodes are
powered off by the READY-handoff ruling, so no node-side probe can run as things stand. Either a
gated rescue-boot check on one node per DC now (closes it inside Stage 4), or split it into its
own gate row targeted at Stage 5 first boot (GA-R6 E3 explicitly permits this; a conditional
close is not permitted)." Operator answer, exact utterance: "split it into its own gate row".
Recorded in the G17 row of docs/CURRENT-STATE.md (the authority); pushed before dependent work.

G17 "Per-DC artifact source reachable FROM A NODE", [V], OPEN. dc0 -> curl 200 from a booted
node against the D-135 item-1 mirror; dc1 -> apt fetches through the proxy at 10.12.68.4:3142,
since dc1's ruled path is the CACHING PROXY with no node-facing mirror (D-135 amendment) and
checking it as one fails by design. Trigger: Stage 5 first boot. The row states that G17 is NOT
a Stage-5 precondition -- Stage 5's bootstrap needs open edge egress for the juju agent stream
and snaps (D-135 items 2-3 unbuilt), a different path from the apt artifact source.

Stage 4 retains bullet 5's rack-side half: the source answers on its own address with an
attested-current sync. dc1's proxy PASSES; dc0 pends the sync re-run.

DOCFIX-204 -- bullet 6 was UNSATISFIABLE and its stale text had spread to four surfaces. "NTP
from the DC's own OPNsense edge working" is superseded by D-129(iv) (RULED 2026-07-21, "Keep
MAAS hierarchy", no NTP role on the edge): the DoD asked for confirmation the edge is the time
source, which the ruling had already refused, so a correctly-built DC could never meet it.
Repaired in the phase-3 DoD (bullet 6 struck, bullet 5 rewritten per-DC), the phase-3 Step 7
(REWRITTEN -- it branched on gap #5 that D-135 resolved, applied one mirror check to both DCs
which fails on dc1 by design, and asked for checks "from a deployed node" that the READY handoff
makes impossible), the workflow-doc Gate cell (which also still said "Nodes deployed",
contradicting DOCFIX-200), the buildout design, and the phase-4 prerequisites (same "nodes
Deployed" error -- exactly the expectation DOCFIX-200 removed to stop Stage 5 breaking).

phase-4 also gains a block making it the OWNER of G17's captures, warning that first boot is the
observation window and missing it forces a deliberate rescue-boot.

Text and gate-record only; no live state touched. repo-lint 0-fail. DOCFIX next-free -> 205.

Revert: git revert this commit; all changes are documentation and the G17 gate row.
