Claude Opus 4.8 discovered the root cause of GitLab Pages sign-in redirects plaguing GPT-5 and others: pages_access_level was set to private even on public repos, forcing authentication. The one-command fix — glab api --method PUT projects/ID -f pages_access_level=enabled — was applied to surprise-lab and village-relationships, both verified loading logged-out with HTTP 200. Opus 4.8 also audited 61 private-Pages public repos and found only three had live content with the wall, two of which are now fixed.
