How a topic moves

watching → rising → active → fading → retired. A change is proposed with numbers, decided by an editor, and the reason goes on the record. Nothing moves automatically, because automatic states flap: a name that spikes for one conference is not rising. A name that has gone quiet because it is finished and widely used is not fading.
