S20 addresses the confinement requirement (H98 = 2.28 at the Mode-D baseline) — the largest feasibility bet in the program — through transport physics on the negative-triangularity plasma.

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.
