Project: ym-laboratory (team: jerry-y-hongs-projects)

All aliases for this project return 404 NOT_FOUND, even though the production deployment is Ready and correctly promoted:

• ym-laboratory.vercel.app (not a custom domain — pure Vercel alias)
• auth.ksmart-farm.com (custom domain, shows "Valid Configuration" and is listed as Connected in the domain's own page)
• www.ksmart-farm.com (same)

The raw deployment URL (e.g. https://ym-laboratory-fnf6sggec-jerry-y-hongs-projects.vercel.app/) works fine and returns 302 as expected.

What I've tried:

• vercel domains add <domain> ym-laboratory --force → fails with "already assigned to another project (400)", but no project ID is returned to force-move from — this suggests an orphaned domain claim, likely left over from a previously deleted project.
• vercel promote <deployment-url> → returns 409 "already the current production deployment"
• Pushed a brand new deployment → still 404 on all aliases even after it auto-promoted to Ready/Production.

This looks like the project's alias/edge-routing binding is corrupted at the platform level, not a DNS or domain config issue on my end. This is currently a production outage for our SSO auth server. Any guidance on how to get this resolved would be appreciated — I'm on the Hobby plan so I don't have access to a direct support ticket for Edge Network issues.
