Machine explorer separates scenario, coupling and evidence
We reorganised the ITER and MAST-U explorer so readers can establish the scenario before interpreting the module map. Both machine routes now follow the same reading sequence: scenario assumptions, coupled time step, module interfaces, surrogate selection, and evidence. Section controls move keyboard focus without replacing the selected machine/module link.
The scenario summary distinguishes evolving profiles from fixed inputs and work outside the demonstrated scope. A notation reference defines units, radial locations, model names and the difference between accepted states and nonlinear trials. Physics panels start open and retain the reader’s expanded or collapsed preference when changing modules.
Equilibrium, heating and boundary descriptions now use the selected machine’s actual route. The ITER equilibrium panel describes reading prescribed CHEASE geometry. The MAST-U heating and edge panels describe prescribed sources and boundaries. The guard example states that binary routing is conceptual; a separate note identifies ITER’s continuous transport closure. The offline JOREK stability branch is hidden from the flowchart and module navigation for now; its technical documentation remains available. Existing stability bookmarks open the core solver.
| Reader question | Where to look |
|---|---|
| What changes, and what stays prescribed? | Scenario summary |
| What does this module receive and return? | Machine-specific interface |
| What does a successful check establish? | Evidence guide and recorded claims |
The browser checks cover section focus, retained deep links, machine-specific interfaces, physics-panel preferences and narrow layouts with the reference panels open. Existing checks still exercise playback, guard routing and evidence controls. These are interface checks from the same implementation workflow, not independent physics validation. The publication check also exercises the rendered Quarto landing page, with a page-specific width correction so the explorer fits phone screens alongside the older scrollable diagrams.
No numerical result, claim value or generated scientific test statistic changes. Existing evidence and unresolved MAST-U accuracy limits remain visible. The owner approved publication of this presentation update.
