Page is a not externally linkable

Wikipedia has a lot of this type of source code on their pages, partly because of their internal linking. It seems clear to me that Google search results will not (and even technically cannot) offer an internal page fragment link unless such an anchor actually exists on the page. Even then, I'm thinking this type of mini sitelink would still rarely be a page fragment unless there were also external links pointing to it - and probably in a significant number.

Thanks for pointing this out. It's the first I heard of it, and historically Google has not paid any attention to page fragment identifiers.
