Paid appointment adapters preserve the provider and price held by an existing
checkout instead of rereading current venue policy after preparation. They accept
an unnamed any-available request and keep retries on the same payment operation.
This is local source work, not a live feature announcement.

Independent public-team visibility and named-booking controls, public selection,
Business/Consumer/Branded companions and final verification remain in progress.
Permissions, assignments, historical appointments and provider configuration are
not changed by this groundwork. No venue setting, hosted database, customer
payment or notification was changed.

See the [contract and remaining companions](../api/APPOINTMENT_CHECKOUT_SNAPSHOT_CONTRACT.md).
