Source: TODO.md §4 (at 9151438)

The queue depth exists in akbasic_AudioState (count - head); no function reads it.

The demo's TUNE label requeues each batch on a wall-clock guess -- it stamps MT# with the
batch's computed length plus a breath, and the sums drift against TEMPO and had better stay
under the queue's 128-note cap when a requeue lands early.

An RPLAY(v) returning notes pending -- same shape as RSPPOS -- deletes the arithmetic.

It also fixes the quiet failure Chapter 7 warns about, where a program QUITs before its music
finishes and never knows.

Files: src/runtime_audio.c, src/play.c, include/akbasic/audio.h
