"mesh_novox_build_agent" is 22 characters; the mesh refused to send the control node its declaration
for it. "agent" keeps the identifier within what an S3 access key allows on every machine.
The builder's manifest with one change that matters: it claims node-build-agent, a node seat, so it
is assignable to every machine with a container runtime, and every holder pulls one build at a time
from the role's one work queue. A tier of many images is then built by as many machines as hold the
seat and are online. The builder module stays until this is assigned where it was; then it goes.
