I've added an acceptance criteria to document how edge cases are corrected. We need to be able to prevent our software from adding certain incorrect categories to its list, override bad guesses, and provide additional edge cases manually.

Initial guesses found in T227874: Investigation: Check Wikidata data on gendered category names were,

• P2521, female form of label - There is precedent to apply this property to categories, occupations, and more.
• P3321, male form of label
• P2959, permanent duplicated item - This is a persistent alias for another item, not a duplicate scheduled for eventual merge.

There doesn't seem to be a "form of label" property for other genders, see https://www.wikidata.org/wiki/Special:Search?search=form+of+label&ns120=1

Another property that is being used for aliasing, but doesn't carry gender information:

• P301, topic's main category - This has been used to link alternative spellings which would be used by the biographical subjects in describing their profession: British theater directors and American theater directors.

Adding an active project tag so this task is shown on some workboard.

Adding WMDE-TechWish to this open task as there are no active project tags on this task since the archival of WMDE-TechWish, hence nobody could find this task on some workboard.
