Materials Qualification

Proving that each material survives its service environment before it goes into a machine.

Every structural and plasma-facing material must be qualified against its real environment — heat flux, neutron damage, cyclic stress, corrosion — through testing. Kronos frames materials qualification as scheduled work on the path to build, with the honest gates (notably magnet cyclic fatigue) named.

Representative material choices are stated; fabrication-grade qualification is future work, not a claimed result.
