9-1-3h, then a Foul vs the FT Shooter

[Freddy]

Lane space player crosses the FT line prior to the ball striking the rim or backboard and then fouls the shooter . . .
When teaching officials the process to follow when this "new" rule is violated followed by a displacement foul against the shooter, I'd like to have an easy-to-remember formula to convey to them. You know, like the four conditions required for a backcourt violation, that kinda thing
Here's what I have so far. Can you help me correct this or improve on it?

1. Delayed violation signal, then personal foul
2. Enforce the violation with a substitute free throw, if nec., clearing the lane
3. Finish the first foul if/as necessary
4. Penalize the last foul” as required with lanes refilled if nec. or throw-in
