Identical titles across pages make them indistinguishable in results and in the index. At scale this is a template that never learned to use the row it was given.
The finding reads:
warning duplicate-title … other pages share this title
Make the title unique: right now it matches other pages, and the results will collapse them together.
Collapsed when it fires template-wide. If it appears on 90% or more of the pages — or of one language version — of a site with at least 20 pages, it is a property of the template and is reported once, with the count, instead of once per page.

Then indexgap brief turns
every finding on this page into a work order in indexgap-briefs/,
with the thresholds the result has to satisfy and the command to check it.
