Everything downstream reads the port: the provider is told where to reach the
consumer, and the redirection that turns a declared port into the number the
machine published is keyed on it. A route naming only its endpoint left the proxy
with no port at all, and a proxy with no port has nothing to dial.
Caught after the catalogue had already been changed to name endpoints and before
the mesh picked those manifests up, which is the only reason nothing broke: every
module's manifest is behind its source right now, so the plan still renders from
the old shape.
The declared port, not the machine one — the redirection happens later and is keyed
on the declared number, so filling in the machine port here would be redirected
twice or not at all. A route that repeats a port keeps it.
