The module's bundle (the one process with the bus) serves the page on the port its manifest declares under listens, from: machine,
and requires a route that reaches it. No form, no script, no verb behind it; any method but GET is 405. A source that does not
answer is said on the page, never shown as an empty list.
Issue 1968.
