ChangesControl-plane service
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The control plane can still report healthy when invalid configuration makes its other routes fail, which could mask a broken deployment and delay detection; the PR is otherwise mergeable with explicit owner follow-up to make health reflect configuration validity.

Summary
Validation
Deployment status
This PR intentionally does not deploy or create remote Cloudflare resources. Production still needs a chosen HTTPS hostname, D1 database ID, Better Auth secret, verified Email Sending domain/address, and final origin allow-list. Cloudflare Email Sending discovery currently returns API error 2036 for the authenticated session, so no sending domain was modified.
