They can be set at the service level using `rules.min_advance_online_canceling` in the Service feed (specifying seconds before the reservation start) or at the slot level using `scheduling_rule_overrides.last_online_cancellable_sec` in the availability feed (specifying an EPOCH timestamp). Slot-level settings override service-level settings. If neither is set, cancellations are allowed up until the slot's start. Implementations must handle `OUTSIDE_CANCELLATION_WINDOW` errors for edge cases.\n"]]
