Subscriptions & Recurring Billing

Subscription management on Stripe Billing or Paddle: plan upgrades/downgrades with proration, grace periods on failed payments, dunning emails, customer portal for self-serve cancellation. Webhook-driven state machine in the DB so the UI never queries Stripe inline. Includes per-plan feature gates wired into the authorization layer.

5 projects carry this capability.
