For
AI-agent builders testing sandboxed construction worlds
Worth noticing
Its theory argues for one-plank walls and more excavators, using a childhood sandbox as its deliberately flimsy proof.

Field notes

The page builds its containment argument as a mock technical paper, complete with axioms, a lemma, a theorem, and a footnote about the “cylindrical penguin.” Its construction premise includes conserved excavated material and connected infrastructure such as pipes, roads, and ponds; the page also lists several named agent-client launch options.
