Build Payment Readiness

Keep the money ledger append-only. Entitlements, invoices, support, and finance views are projections from owned events. Support corrections are new reason-coded ledger events, not silent edits. Do not confiscate value because a score moved. Provider dashboard truth is not the product ledger.

Read current official provider, store, tax, and dispute docs for the selected channels. Open payment platform patterns for channel behavior and billing reconciliation for settlement and close.

Use operate-marketplace-payouts for two-sided seller payouts. Use design-price-increase-retention for raising live prices. Use design-refund-support-flow for entitlement consequence after a refund.
