36    "The initial injected infinite loop used DevTools Runtime.evaluate; the error UI appeared and terminate was called, but the inspector worker target remained attached. Injecting a normal worker message task instead verified actual worker termination. No production deadline was relaxed.",
37    "The stronger seeded-progress assertion initially compared a pre-acknowledgement pause save against the accepted paused position (2 cm of gravity settling). It now waits for the simulation pause acknowledgement; final assertions require exact position, inventory, flags and doors."
