Wikipedia:Wikipedia Signpost/Templates/Single talk
You just transclude this on the talk page for the single issue. See Wikipedia talk:Wikipedia Signpost/Single/2022-11-28 for an example.
The entire source code for one of these talk pages should just be:
{{Wikipedia:Wikipedia Signpost/Templates/Single talk}}
Technical notes edit
Similar to Wikipedia:Wikipedia Signpost/Templates/Issue pageviews (which is itself transcluded at the end busted because graphs don't work).
The core of this is Wikipedia:Wikipedia Signpost/Templates/Article list maker, which uses Module:Signpost to fetch article lists from indices.
These indices are at places like Module:Signpost/index/2022. These indices are (as of December 2022) populated by User:Mr._Stradivarius/gadgets/SignpostTagger.
Another task of the article list maker is to apply custom formatting to the entries it gets, which it does here according to the template at Wikipedia:Wikipedia Signpost/Templates/Article list maker/Comment section.
One thing to note is that this template (Single talk) uses kind of an ugly hack to get the date out of the page name:
{{#invoke:string|sub|{{PAGENAME}}|27|36}}. Essentially, it gets "2022-11-28" as a substring of {{PAGENAME}}, like this:
Wikipedia talk:Wikipedia Signpost/Single/2022-11-28111111111122222222223333333123456789012345678901234567890123456^ ^
This means that it will only work right on pages whose titles follow the exact format of "Wikipedia Signpost/Single/YYYY-MM-DD". This shouldn't be a problem, but it could become one, and I want you to know about this if it starts breaking for no reason.
Update: I fixed it, due to being a genius. Now it uses magic words, namely titleparts, to do this in a smart way:
{{#titleparts:{{FULLPAGENAME}}|3|3}}
