Payment return received.
This sandbox return is recorded for qualification. Access is activated only after an approved workspace binding and a verified Stripe webhook.
Stripe owns payment data
Payment details stay on Stripe-hosted checkout. NEF receives bounded billing events, not card data or credentials.
Trials are activation-bound
A checkout redirect alone does not grant access. The customer workspace, principal, price, and evidence must match before entitlement is admitted.
The bundle is one offer
The combined subscription is billed at $29.95/month and maps to both product entitlements through the governed catalog.
