On 2.10.29 such a consumer was moved past a message now and then without
handing it over; the controller's events consumer has seven filters, and a
merge on the stream never reached it. The test reproduces the skip on 2.10.29
and keeps the image's release equal to the server it tests.
A Go bundle the runtime launches beside the nats module's server. It reads
the server's monitoring API and the composed user list — never a password
hash — and changes nothing. Reached directly when the endpoint is published,
through the container otherwise: its configuration binds monitoring to the
container's own loopback, so the published port answers nothing today.
