Research brief
No brief on file. This article was written before the brief gate existed. The next pass must fill one before touching the outline.
Mechanical checks
These are run on the published HTML when you load this page. They are the checks a machine can do. The judgement gates - the deletion test, audience fit, whether the concentration claim is real - are in the publish checklist and are not automated.
