Three systems needed to know what content existed, and for a while each kept its own list. The lists disagreed. Now one catalogue is generated from the site itself and shared by training, help and the social plan.
Help articles live in the same repository as the product. Every explainer film must have its file and poster, and every article must render with the real components, or the build fails. Retired material stays in the catalogue with an explicit do-not-post status, because hidden things come back.
It removed the conflicting lists and made omissions detectable.
