Abstract Like most magnetic confined fusion experiments, the ST40 tokamak started off with a small subset of diagnostics and gradually increased diagnostic set to include more complex comprehensive systems. To make each operational phase, forward models various are used developed aid design, provide consistency-checks during commissioning, test analysis methods, build workflows constrain high-level parameters inform interpretation, theory modelling. For new workflows, minimum-viable-products released early, their complexity is in step-wise manner, facilitating support all programme phases on multiple parallel applications, while enabling learning opportunities feedback loops. In this contribution we review philosophy, scope architecture framework under development. We discuss details some models, examples how they investigate methodologies through synthetic data, embedded experimental workflows. compare previously published results new, advanced employing recent, detailed providing confirmation material from 2021–22 campaign.
