KEDGE

BUILT
edge-transport

divertor / edge heat-flux → target-thermal surrogate — maps divertor heat flux to target surface temperature + material limits (W / CuCrZr) from the H9 exhaust scan. q→T_surf fit **R²=1.0** (77 pts); CuCrZr material limit **q~13.5 MW/m²**. Reduced 0-D thermal model — SOLPS-ITER/EIRENE edge campaign is the fidelity upgrade.

Headline benchmark — honest, computed
divertor edge surrogate: heat-flux→target-temp R²=1.0, CuCrZr limit q~13.5 MW/m² (reduced 0-D; SOLPS/EIRENE = upgrade)

What it accelerates

KODEX KEDGE is a fast, calibrated surrogate for SOLPS-ITER / EIRENE edge campaign — reproducing its result at inference speed, so it runs inside a real-time control loop or a design search where the full computation is far too slow to call.

Use it

One line, one contract — a prediction, its uncertainty, and whether the input is in-domain.

from kronos_ml import KEDGE

model = KEDGE()                          # loads the trained surrogate
y, sigma, in_domain = model.predict(x)   # y = edge-transport prediction
if not in_domain:                       # out of its trusted region
    fall_back_to_full_physics()          # KEDGE abstains, never extrapolates

How to trust it

Every KODEX code wraps the shared spine — KHALO for calibrated uncertainty and KGATE for the out-of-domain gate — so it reports how confident it is and abstains rather than extrapolate. Benchmarks are computed on held-out data with a fixed seed; pre-registered misses are kept, not hidden.
