Panel 1
A public pump fails; its polished service hatch has no screws, only a sealed maker’s plate with a distant service symbol.
Caption: The pump belonged to the block. Its broken part belonged to someone else.
MECHANIC: It wants an authorized century.
Panel 2
Residents try proprietary keys and useless sealed manuals while water vessels queue.
RESIDENT: Does the warranty carry water?
Panel 3
The crew drills out the seal, repairs a simple belt, and replaces the hatch with common screws—leaving one bright screw visible.
MECHANIC: Last screw stays ordinary.
Panel 4
A child opens the hatch with a shared driver as clean water runs; a three-knot repair notice hangs nearby.
Caption: The machine lost its seal and regained its purpose.
CHILD: It opens.
