What each one reported

Base44: One prompt, one build, 8 of 8. Base44 created the backend entities itself (Booking with create/list) and ran its own end-to-end check in the editor. The app was only reachable after clicking Publish — before that the public URL answered 'This app is not available yet'. The subdomain is auto-generated (inescapable-still-point-flow.base44.app); Base44 suggests buying stillpointbooking.com. Email delivery requires a paid plan and a verified domain and the confirmation screen says so explicitly. Same limitation as Lovable, same pass under A6.

Lovable: One prompt, one build. Published at still-point-studio.lovable.app — the plain name 'still-point' was already taken, so Lovable added the suffix on its own. No confirmation email is sent: the app states on the confirmation screen that email sending needs a paid plan and a verified domain, which satisfies A6 as written. The admin page is open to anyone by design, as the brief asked. Lovable also reported its own 390 px check in the chat; we verified it independently and it passed.
