State machine

Task

A task is in one place at a time: new, processing, backlogged, failed or completed. The places are the cases of a PHP enum, and the definition lives in attributes.

Article

An article can be in several places at once: a journalist and a spellchecker review it in parallel. Guards check the roles of the connected user.
