The eighth floor's Earth memories render people as intangible recordings while making their clothes, vehicles, carried objects, and other moving possessions physically interactive and dangerously forceful.
Replayed people do not perceive crawlers, but contact removes their material clothing and possessions. A tourist kicks Donut down stone stairs, and Carl can take a functioning phone, wallet, money, shoe, map, and other objects from otherwise unaware images.
Vehicles and moving objects carry artificially dangerous force despite crawler attributes that should resist them. Separated replay bodies continue their recorded actions as floating heads and arms, while removed objects become dust when the floor ends. Carl concludes that even minor interference can create escalating environmental disasters.
Translucent human outlines continue walking while abandoned clothes, phones, vehicles, and other solid objects scatter around them.
These rules turn ordinary reconstructed civilization into a persistent physics hazard and exploitable source of objects.
