  "_comment": "Regression test for the fixed NRPN out-of-bounds write (TODO.md Critical finding #1: JaySynth::handleController wrote last_midiCC_info[midiCC_info.ID] with no bounds check; NRPN IDs assemble to up to 16383 but the array is sized NUM_MIDI_CONTROLLERS=1024). This sends the maximum possible 14-bit NRPN ID (127<<7 | 127 = 16383) via the standard MIDI NRPN CC sequence (99=NRPN MSB, 98=NRPN LSB, 6=Data Entry MSB, 38=Data Entry LSB, 98 again to complete/trigger the sequence - see MidiNrpn::process). Before the fix this reliably wrote far outside the array; after the fix, handleController returns immediately for any out-of-range ID. Success = process completes without crashing/hanging and produces valid, NaN-free audio.",
