Central modules are able to detect internal errors which could block the display of a page, like in development phase but also later.
And that can happen in any wiki-project without enough helpers, then central categories and alerts for central modules seem usefull to help them.
== Problem ==
Central modules are able to detect internal errors which could block the display of a page, like in development phase but also later.
And that can happen in any wiki-project without enough helpers
== Who would benefit ==
All simple readers of wikis. Also all Lua-coders to repair problems.
== Proposed solution ==
Central modules already detect errors and display them in errors messages and categories, see T135845 and the draft of [[ https://fr.wikisource.org/wiki/Module:Central-s-fr | fr.wikisource Central modules ]].
Create central categories and alerts for central modules.
Declare and activate categories and alerts each time a problem is detected by central modules.
For each problem, report datas: link to the involved page, error details...
Report in short in the category, with more datas in alerts, then with detailed datas in the page itself.
Report these in the local wiki and in the central repository T121470.
Report these in wiki, user and content languages.
These reports must enough suport Lua-coders to locate and repair the problem/s.
== Where and when to use these categories and alerts? ==
For all pages with central modules, but perhaps also for mediawiki, extensions, bots...
Each time when we edit a module or a script or a template and then clic on "Show preview".
