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

The derivation of the economic gain factor, Q_econ, results in nonlinear equations with ten controlling normalized design parameters ranging from fusion power density and surface component lifetime to energy fluence, price of energy, and component efficiency and cost. These criteria are independent of the power plant's absolute power and impartial to the particulars of its fusion technology.

C2weakest assumption

The model exploits temporal equilibrium, and engineering and cost parameters normalized to the energy capture surface, allowing the derived criteria to be independent of absolute power and impartial to fusion technology specifics.

C3one line summary

A framework derives the economic gain factor Q_econ from ten normalized parameters to set criteria for fusion power plant viability independent of absolute power or specific technology.
