description	Wire a domain the user ALREADY OWNS (GoDaddy/Namecheap/Cloudflare/…) to their Convex app: exact DNS records, custom-domain attachment, auth-origin rebind. TRIGGER when the user owns a domain and wants it pointing at their app ('point my domain at this', 'use my own domain', 'set up example.com'). Never asks for registrar credentials.

Custom domain with your own provider (/domains)

Point a domain the user already owns at their Convex app. No purchase, no registrar credentials — you give the user the exact records to create themselves.

Procedure

1. Identify the target: the published site host (for static hosting) or the deployment's HTTP actions URL (npx convex env get CONVEX_SITE_URL or the dashboard).
2. Give the exact DNS records to create at THEIR registrar: the CNAME (or A/ALIAS at the apex) plus the TXT verification record — concrete host/value strings, not placeholders.
3. Attach the custom domain on Convex (dashboard → deployment → Custom Domains, or the CLI) and wait for verification. DNS propagation can take minutes to hours — tell the user, don't poll forever.
4. If the app uses auth (passkeys/OAuth), rebind the auth origin (SITE_URL / RP_ID / ORIGIN env vars) to the new domain and re-deploy — otherwise sign-in breaks on the new domain.
5. Verify: the domain serves the app over HTTPS, including the apex → www redirect if configured.

Rules

• Never ask for registrar credentials — the user creates the records.
• Always include the TXT verification record, not just the CNAME.
• Rebinding the domain changes the auth origin — re-deploy after, or sign-in breaks.
