Perception to Control: The Handoff Nobody Owns
The perception team ships a detector that meets its accuracy target. The controls team builds a controller that is stable given its inputs. Both are right and the robot behaves badly, because what crosses between them is not a detection, it is a detection with a latency, a coordinate frame, a timestamp, and an uncertainty, and only one of those five is usually specified.

Perception Accuracy Is Not Control Safety
A 99 percent accurate detector is not a 99 percent safe robot, and the gap is not a matter of degree. Safety depends on which errors occur, how they are distributed in space and time, what the system does when it is uncertain, and whether the safe behaviour is enforced somewhere the perception stack cannot override.
