GA-R5. Operator utterance: "Dedicated region VM per DC at utility .6
(Recommended)".

The region DB must not share fate with the hypervisor running every node it
manages -- also a precondition for D-132 q3 cross-site backup custody, which
stays pinned. The D-134 standing octet map now reads .4 artifact service /
.5 juju controller / .6 MAAS region, binding at every future DC standup.

Build notes carried, not ruled: author BOTH metal-admin and provider-public
legs at creation (the identical under-carve on the juju controller VM cost
three bootstrap attempts today); re-measure capacity before applying.
