Continuous ball track in the same mesh timebase as the players. The measured ball is the primary input for pass, interception, shot, and goal plane-crossing — not an inferred path.
Measured ball trajectory.

One active ball. Tracks are never fused.

Previous active off-pitch ≥ 1.0 s
With two balls in play the system raises a visible alert rather than guessing which one matters.
