Opinions please. Good catch or picking nits?

Same NCAA game as the other post.

Time winding down in the first half. Team A scores with 3 seconds left. B1 grabs the ball, steps OOB, turns, then steps slightly but clearly over the OOB line and releases the throw-in.

Whistle blows for the violation, clock clearly at 1 second. Clock continues and horn sounds.

First, do we call the violation? There were Team A players nearby, but no one pressuring the inbounder. The calling official is certain that the player stepped inbounds, but is probably the only one who saw it. So do we have a whistle or not?

Second, if we do have a whistle, can we just say "that's the half" after the horn sounds? We put 1 second back on the clock, thinking that NCAA doesn't allow for lag time.

Thoughts please.
