Waiver "I certify" checkbox is now enforced

Fix

Week of May 19, 2026

The certification checkbox on the waiver review page (step 3 of the signing flow) is now required before a prospect can submit the Sign Agreement button.

Browser-side — the checkbox carries an HTML required attribute, so the browser surfaces the standard “please check this box” prompt if a prospect tries to submit without it.
Server-side — if the form is bypassed (older browser, JS off, scripted submission), the server now rejects the request and re-renders the review page with an error message.

Before this fix, the checkbox was rendered alongside the form rather than inside it, which meant browsers ignored the required attribute and the server didn’t see the checkbox value — submissions went through unchecked.

Previously-signed waivers remain valid. This is a tightening of the signing flow only — no data correction needed and no prospect needs to re-sign. The legal text and signature record on existing waivers are unaffected.
