The RIDER is the check-in primitive. Appends rider_checked_in; the booking’s state becomes checked_in on the first rider (and the header shows checked_in_count/riders_count). units: [{resource_id}] assigns bikes at the same tap through the assignment guard (409 unit_busy inside units[].status). A repeat is {already: true}. A released seat after the departure started is 409 seat_released. Session, or an operator key scoped bookings.write.

Header Parameters

x-tenant-id

required

Tenant identifier (UUID).

Authn/authz semantics are intentionally TBD for this contract slice; this header exists to keep the contract explicitly multi-tenant from day 0.
