Category:Template Category TOC on pages where PAGESINCATEGORY returns zero

This is a tracking category. It is used to build and maintain lists of pages—primarily for the sake of the lists themselves and their use in article and category maintenance. It is not part of the BTW's categorization scheme. More information: This category is hidden on its member pages—unless the corresponding user preference is set. These categories are used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications).

Administrators: Please do not delete this category as empty! This category may be empty occasionally or even most of the time.

{{Category TOC}} uses {{PAGESINCATEGORY}} to count the number of pages in a category.

However, as of 1 April 2020, there seems to be some issue with {{PAGESINCATEGORY}} falsely returning zero in some cases. This category tracks all pages where the count is reported as zero (or less), so that the veracity of the number can be checked.

This category should contain only pages labelled as "empty". But until bugs in the Wikimedia software are fixed, it will include some non-empty categories. For more info, see w:phab:T18036 and w:phab:T221795.
