A contained signal crosses into output that goes public.

The system suffered from a lack of object permanence, meaning it failed to maintain awareness of the cat's presence once it was out of sight beneath the vehicle. Consequently, the robotaxi drove forward while the cat was still underneath, ignoring a bystander's attempt to rescue the animal.
