foundation_dns → nameservers.type checklist

1. What are you migrating?

API client that PATCHes DNS settings Terraform / OpenTofu managing zone DNS settings Generated SDK / closed enum for nameservers.type Read-only dashboards / not in the write path

2. Do you still write `foundation_dns`?

Yes — still sending the bool (alone or with type) No — already on nameservers.type only

3. Dual-write risk?

Sometimes send both foundation_dns and nameservers.type Single field only

3b. Terraform situation

Deleted arg becomes false then null — perpetual plan drift Using ignore_changes=all / broad ignores as a band-aid Ready to manage nameservers.type explicitly
