Disqualified Player - Oops

[Sven]

Yesterday, boys' 8th grade game.

A1 commits a common foul near the end of the game. I report it and go to trail position. Partner administers
1 + 1 to B1. Shot is missed. B2 puts back the rebound.

During this action, I observed A team coach conferring (or so I thought) with A1 near their bench.

Immediatley following the B2 basket, A team coach steps onto court hollering; he yells that A1 has five fouls. (Never mind that he could have been T'd for coming on to the court. At the time, I was thinking, "Good grief, what the heck is going on?")

He sends sub to check in for A1.

I've still heard nothing from the scorer to this point, so I check. Yep, that was A1's fifth. Drat.

Coach A is asking for the B2 put-back to be wiped off the board because it's a correctible error. Partner and I confer and decide that it isn't a correctible situation. We play on with team A to inbound.

In looking a Rule 2-10-1, I still don' think it applies in this situation, but I need some help here.

Three questions:

1. Was this a correctible error situation?

2. If so or if not, what could/should we have done differently?

3. Given that it was our 'screw up' would you have given a technical foul to A team coach for coming on to the court during the dead ball following B2's basket?

By the way, I realize, after the fact, that in this situation, I should have taken just a moment more when reporting to see if the table would indicate a fifth foul. Just goes to show once more the importance of good communication between the table and the on-court officials. I'll be more cautious in the future.
