PROJECT REFERENCE
Quotes, setup/maintenance subscription checkout, invoices, cancel/discard and guest purchase contracts. ServiceBillingProvider supports sandbox or explicitly gated live configuration; creation requires checkout/cards-only/method configuration gates. Webhook signature verification and invoice/refund reconciliation code exists.

OBSERVABLE BEHAVIOR
- Quotes, setup/maintenance subscription checkout, invoices, cancel/discard and guest purchase contracts.
- ServiceBillingProvider supports sandbox or explicitly gated live configuration; creation requires checkout/cards-only/method configuration gates.
- Webhook signature verification and invoice/refund reconciliation code exists.

TYPED CONTRACT
- BillingEnvironment: sandbox | live
- Quote: initial + monthly + currency + fingerprint + terms version
- SubscriptionState: provider-bound
- InvoiceEvidence: amount + paid/refunded state

DECISION RULE
Persist the invoice/subscription status; never treat a redirect or advisory forecast as payment.

CONSUMER RULE
Read the result status before interpreting its value. Preserve the tenant, project, source version and evidence context. Do not treat a missing record, an unexecuted proposal or a successful computation as an authorized external action.

EVIDENCE LIMITS
- Distinct from merchant payments, which are currently test-only.
- Source ability to configure live is not evidence live billing is activated.
- No subscriptions were created or changed.
