-SC0000 label_1235a reaches this when the OR of 0x1c7 message-skip and 0x1cc read-skip state is zero (normal playback). Native run-state bit 0x400 yields the interpreter while the queued foreground presentation advances. The interactive port starts pending 0x223 commands here, parks only the VM thread while per-frame compositing continues, and resumes after natural or click-forced completion.
+SC0000 label_1235a reaches this when 0x1c7/0x1cc are zero. Native run-state bit 0x400 parks the interpreter while gfx_render_frame repeatedly samples finite one-shot object channels and queued surface commands; op 0x224 follows after dirty state clears. Native trace proves AE001D bind, mode-1 0x203, and 0x202 targets complete in one 5 ms batch with no render, then first compose here. The port publishes and waits for visible finite one-shot channels or 0x223 commands; click forcing remains limited to the latter.
