S79 closes one of the coupled physics-to-engineering constraints that make the MetroVolt design point self-consistent.

What the register records

Cuts both ways: wall-stabilised β_N=5.0 buys +24% Pfus at unchanged H98; n_e/T_i −10% degrade gracefully; but I_p −10% is NOT recoverable by density trim — plasma current is the least forgiving parameter.
