Situation: A14 is shooting a 1-and-1 for a common foul. Lead bounces ball to shooter, then horn buzzes, then B24 runs on the court without being beckoned. B12 on the near block starts to leave the game, and B24 starts to take his spot on the lane. We whistle and decide we have to assess a T.

Two possibilities:
10-1-6: it's a team technical to "Have more than five team members participating simultaneously."

10-2-2: it's a player technical for a sub to enter the court "Without being beckoned by an official, except between quarters."

So it sounds like an obvious violation of 10-2-2, since nobody beckoned the sub. However, look at 10.2.1(A):

10.2.1 SITUATION A: Substitute A1 enters the court without reporting to the
scorer. The infraction is discovered: (a) before the ball becomes live; or (b) after
the ball becomes live. RULING: In (a), a technical foul is charged to A1. In (b), it
is too late to penalize A1.

Since the ball was live when we "discovered" the infraction, it seems to be "too late" to penalize B24. The same principle appears in 10.2.2: you call a player T only when the ball is dead and the sub enters without being beckoned.

So here's the question: do we have different fouls depending on whether the ball is live? If it's a dead ball, we penalize under 10-2-2 with a player T, but if it's a live ball (as in our sitch) we penalize under 10-1-6 with a team T?
