The default behavior is that a wiki area header will also display on any wiki pages within that area. The VW3 importer does not import any headers at the wiki page level -- only the area level. If the header was added by the importer, it was added to the article's area, not the article itself. So the area must be related to node 176 (such as it is the imported wiki version of node 176), and the article is within that area.
Please note that if a user added this header since the import, the header could be anything with any or no relation. Unlike VW3, VaultWiki 4 allows you to select any wiki page to be a header, and you can reuse the same page for as many headers as you want. If the header has the preview bit set, then it has definitely been modified by a user (although not having the preview bit does not mean that a user did not edit it), and cannot be trusted to be the same data that was imported.
At this point, the only way to know for sure if a header was created by the import or a user would be by looking at clues in the raw data. The vw_integrate.title field, which is not used on the front-end for these types of headers, would differ in the following ways:
- For imported headers, 'Header for [name of the header target]"
- For user-generated headers, 'Header for [ID1]:[ID2]'
This only holds true if vw_integrate.adminset = 0, which designates that the row was not added via the admin panel. If it is 1, there is no way to tell the difference. However, this still only tells you if the header record was created by the import; if it was edited by a user since the import (and the user could have changed the header content as part of the edit), there is no way to tell the difference.
I would only suspect there to be a bug if:
- The database shows no user-generated header records
- Every header record is either associated to the wrong target area or has the wrong wiki page associated as the header content
And this could only be confirmed with file access so that the incoming import data could be checked for errors at each part of that import conversion.
