Programmable-Matter 'Shape-Shifting Craft' Claim

THEORETICAL/FRINGE; binding wall just-hard (thermal) -> Stefan-Boltzmann ceiling; not built.
Unbuilt; ~10^9x short of the real motile-swarm ceiling (Kilobot 1,024, 2D). Refuted by a just-hard thermal wall (421 C glow @1uW/unit; 3871 K vaporize @1mW), NOT fundamental physics. The one live 'if it worked' path is a PRESENTATION swarm (shimmer/metasurface), which converges on the prosaic drone-swarm explanation.
