The mistakes were made, fixed, and shipped past — before you got here.
Double-clicks and retries never create a duplicate submission.
Circular show/hide rules are caught before a form ships, not after.
Failed webhooks retry with backoff — a timeout never means silence.
Bad file uploads are rejected at the field, before they touch storage.
The person filling out your form is the same user your auth and CRM already recognize — no reconciliation layer. Form submitted → CRM contact created → onboarding flow triggered. Zero glue code.
