RULING: A1 will attempt the free throw with the lane spaces occupied as required. The fourth period time has not expired until the period-ending signal.

As I said, that test question evolved from this case play and has been used several times already iirc.

I'm sorry, but the OP reads differently than this, and seems to me to be a relic from the days of lag time. "Just prior to the horn sounding" indicates to me that the horn does indeed sound, immediately after the foul, and therefore the period will be over as soon as the final free throw is completed.
