The Physics De-Risking Register: Gate-by-Gate Evidence, Independently Re-Run and Stamped, Across a Compact Spherical-Tokamak Breeder and Its D–³He Tandem-Mirror Burners

The Physics De-Risking Register is the public, gate-by-gate evidence layer for the Kronos compact spherical-tokamak breeder and its D–3He tandem-mirror burners: every headline anchor carries a gate serial and is independently re-run and stamped.
