DOCFIX-195: office1-netbox holds the VR1 IPAM apex role; apex write-back deferred; C2 redefined ...

Operator ruling 2026-07-15: office1-netbox (10.10.1.10) HOLDS THE IPAM APEX
ROLE during VR1 -- the authoritative NetBox every consuming system (OpenTofu,
MAAS, overlays, bundle) derives its values from. It is a working draft (edited
as the buildout proceeds), but it is the apex. netbox.baldurkeep.com takes NO
write during VR1; it is the eventual production apex, frozen as a read-only v1
reference draft. Merge-back is deferred to end-of-deployment (a maybe), NOT a
Stage 2 gate.

The repo encoded the opposite roles and defined close-out C2 (the last Stage 2
gate, and the branch->main merge trigger) as an operator-gated write UPSTREAM.
Under the ruling there is no apex write in Stage 2, so C2 is redefined:
office1-netbox holds the COMPLETE validated dataset -- carve + six-plane roles
+ both DCs + the D-120 compose-/24 child ranges + the two service IPs -- and it
is VERIFIED. C2 stays OPEN.

Finding surfaced while drafting (logged, not fixed): the D-120 objects are
ip-ranges/ip-addresses, object classes the sandbox loop does NOT cover
(prod-draft-dump.py ENDPOINTS and sandbox-fidelity-check.py KEY/EXPECTED_NEW
both stop at rirs/roles/regions/sites/aggregates/prefixes). So the hardened
fidelity check cannot verify the D-120 load; verifying it needs a tool
extension (+harness) or a recorded manual read-back. Confirmed no live system
config points at any NetBox URL -- documentation-only change.
