It does show up on https://en.wikipedia.org/wiki/Category:Candidates_for_speedy_deletion and https://de.wikipedia.org/wiki/Kategorie:Wikipedia:Schnelll%C3%B6schen under Patois. This one turns out not to be Wikibase’s fault at all. Wikibase correctly passes a `jam:Category:Kiandidet fi kuik-kuik diliishan` sitelink into the ParserOutput; but MediaWiki can’t parse it – compare my sandbox <https://din.wikipedia.org/wiki/Dulooi:Lucas_Werkmeister_(WMDE)/sandbox>: F33926732: Screenshot_2020-11-27 Dulooi Lucas Werkmeister (WMDE) sandbox - Wikipedia.png <https://phabricator.wikimedia.org/F33926732> The solution to this riddle is that **Jam is the Dinka name for the Talk namespace**, and therefore this interwiki link is actually parsed as an internal link, and no link to Patois Wikipedia is generated. (As far as I can tell, this means it’s not possible to link from dinwiki to jamwiki at all, whether through Wikibase or manually, unless you “take a detour” with something like `[[en:jam:...]]`.) One way to solve this would probably be to change the interface by which Wikibase communicates the sitelinks to MediaWiki: currently, we have an object like `{ siteId: 'jamwiki', title: 'Category:Kiandidet fi kuik-kuik diliishan' }`, which we then turn into a string only for MediaWiki to try to parse it again – and MediaWiki interprets the string differently than we intend, and thinks the `jam:` indicates the Talk namespace. But that doesn’t explain why e. g. the Tamil sitelink for Q7086090 <https://www.wikidata.org/wiki/Q7086090> is missing on Spanish and English Wikipedia.
