Lab · AT-0
Reproduction engine
Reproduce known and hand-checkable relational-geometry behaviour. Every run is deterministic in its seed, model version and algorithm version.

An unimplemented constraint returns NOT MODELED. It never returns PASS.

Graph connected; shortest-path solution finite and NaN-free.
AT-0 has no time coordinate, no Lorentzian structure and no light cones. Causal behaviour cannot be evaluated until AT-4.
No stress-energy tensor is defined in this model. Energy-condition analysis begins at AT-5.
Whether these graph distances embed into a recognisable manifold is untested until AT-3.
No mapping from relational couplings to measurable physical quantities exists. Graph-distance reduction is not physical distance reduction.
