Abstract: Replication data for the paper A Real-Time Control Suite for a Compact Negative-Triangularity Spherical-Tokamak Breeder: Profile, Shape, Vertical-Stability, q-Profile, and Solenoid-Free Ramp Controllers (Kronos Fusion Energy 2026 Publication Series, paper 2.75), published at doi:10.5281/zenodo.22645809. Abstract of the paper. A compact, high-current spherical tokamak leaves little time to react and no room for an uncontrolled excursion, so its controllers must be simultaneously fast, coordinated, and provably safe. We present the real-time control suite for the Hyperion breeder (design point =9.66, Q=3.076, P_ fus=85.04, negative triangularity δ=-0.30, on-axis field B_0=8, elongation κ=2.0, major radius =1.20, aspect ratio A=2.5, centrepost peak field 16.84): a family of seventeen closed-loop controllers spanning core profile, plasma shape, vertical stability, q-profile and solenoid-free current ramp-up, unified beneath a single certified safety layer and organized within an eight-layer (L0–L7) control architecture in which data rises and every command descends through the clamp. We write the plant as a control-affine coupling of the Grad–Shafranov equilibrium, the poloidal-flux (current) diffusion equation, a flux-driven transport closure and the axisymmetric conductor circuit, and we cast each control objective as an explicit tracking-or-constraint problem; the estimation front-end is a graph-neural-network sensor-imputation stage feeding a physics-informed equilibrium surrogate with calibrated uncertainty, and the safety layer is a control-barrier-function (CBF) quadratic program that projects any commanded action onto the nearest action keeping the closed loop inside the certified safe set \ 3.5\. What this dataset contains data/key_values.csv and data/anchors.json: the frozen design-point values quoted in the paper (symbol, value, unit, provenance), in machine-readable form. data/verification.csv: the validator gates the paper cites, each with its verdict and a link to a live recompute page. figures/: the figures from the paper, as vector PDF, with an inventory. a-real-time-control-suite-for-a-compact-negative-triang.data-methods.pdf: methods, the computational codes used, and the full value table. data/data_dictionary.md: column definitions. Every value is a frozen design-point number that is independently re-run and recorded in the Kronos Physics De-Risking Register (doi:10.5281/zenodo.22645689).
