EventIngest refreshed a stream's cache through StreamProcess::updateStream(), which finds MAIN in the global server list. The cluster API's bootstrap loads none, so the job was queued for server 0, whose signals nobody reads. After a node started or stopped a stream, MAIN's cache kept the old state until the next full rebuild, up to five minutes: viewers of a stream that had just started got the off-air clip. The job is queued for MAIN's own id.
