State
St is the world at time t. Ot is a view of that world. At is an action. The runtime persists S, not a reel of frames. This is the entire thesis.
S_{t+1} = T(S_t, A_t, C)
O_t = R(S_t, V_t)
report = V(S, constraints)Persistence
A world has an identity. Forks copy that identity into a branch. Rollback restores a prior S. If the only record of the world is a generated clip, none of those operations exist.
Schemas
Orbital mechanics is positions, velocities, masses, and a potential. A circuit is nodes and currents. A warehouse is SKUs and poses. The runtime is shared. The schema is not. We will not invent a universal object and call it physics.
The instrument
The landing page runs an orbital-mechanics schema on an exact-physics backend. Drag to look. Fork Δv. Verify energy and eccentricity. Commit or roll back. That is a world, not a demo video.
