novox/hq 04-ISSUES/146. A push consumer delivers onto an ordinary subject and everything subscribed to it gets a copy. The controller holds a consumer called 'controller' on CONTROL and another called 'controller' on EVENTS, and both were given _DELIVER.controller — so the one process, holding both subscriptions, acted on every message twice. Measured: one enrolment published, one message in the stream, one delivery, no redelivery, and the controller enrolled the machine twice — the second minting a credential that replaced the one the machine had just been handed, which is why it then reconnected for ever as a user whose password the mesh had rotated. Every report and every followed event doubled the same way, silently. The stream goes in the subject because the pair is what identifies a consumer. A subscriber's permission gains the same shape, keeping the bare name so an existing consumer keeps working until the next assertion moves it.
