The headless divergence that sent us chasing a phantom 'sleep' spin: op 0x72 wait-for-input was a no-op headless, so a run plowed past all 166 of a scene's prompts into code no real playthrough reaches (SC0000 -> the name-entry poll loop, spinning sleep 1 493k x to STEP-LIMIT). That path is a fiction. Fix: VmOptions.HaltAtWaitForInput -> the VM halts (reason 'wait-for-input') at 0x72. run/play default to faithful (SC0000 now halts at ~402 steps, 0 sleeps, matching the real run's path to the first prompt); --plow opts into the old walk-every-page coverage. sweep stays plow by default (dialogue oracle, 284/13 unchanged); --halt-at-wait makes all 297 scenes halt cleanly at their first prompt (0 STEP-LIMIT). Godot unaffected (really blocks on input; flag false). Engine 58/58 (2 new); sweep default 284/13 unchanged; Godot selftest OK. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
