S80 computes the plasma equilibrium and operating space — the self-consistent balance of pressure and field that fixes the machine's shape and stability margins.
What the register records
Eight-constraint feasible region over (n_e, T_i0), 667 coupled evaluations per posture: 36% of the plane closes with P_net>0 (graceful room, not a knife-edge); the Troyon upper edge opens +10% in density under wall-stabilised β_N=5.0.
This is a register summary of a deposited analysis; its title and notes quote the deposit as-run, so parameters here may reflect the pre-Mode-D basis where they differ — all operating claims cite the frozen Mode-D point (ratified 24 July 2026). Full input decks, scripts, and output data for every analysis S01–S81 are released openly under CC BY 4.0 at DOI 10.5281/zenodo.21746479.
