The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

In a cosmological scenario involving two scalar fields, one field governs the cyclic evolution of the universe while the other drives an inflationary phase after each cosmological bounce, suggesting that inflation may be a recurring feature of a cyclic universe.

C2weakest assumption

That suitable potentials and interactions for the two scalar fields can be chosen so that one produces stable cyclic behavior while the other reliably triggers inflation immediately after each bounce without destabilizing the cycles or violating observations.

C3one line summary

A two-scalar-field model integrates inflation as a recurring feature after each bounce in a cyclic universe.
