The packages step sealed the build agent its genesis document and pushed, and the push returned as soon
as it was sent. The sdk step then asked for the SDK's build at once, and the agent reads the document
from the file the node writes when it applies that push: one genesis found it in time, the next was
refused for having neither a binding nor the document. That one push now waits until the node reports
it applied it (push --wait); every other push still returns on sending.
The bus reads its user list from a file that, until the broker step adopts it as the nats module,
only the installer writes, and the installer wrote it only at enrolment. The build agent's account,
minted with step 13's push, never reached the bus; the agent was refused (Authorization Violation)
and the sdk step's build waited until it was killed. Every push genesis makes now places the composed
list and has the bus re-read it, until the nats module is registered (ADR 0331 §5, ADR 0333 §4).
