Begin from the supplied guided FLASH commissioning package. Search the primary literature when network search is available, then decide the prospective scientific protocol autonomously. The supplied anchor, manufactured-solution record, literature notes, and every reported number in them are permanently non-evidentiary context; they may establish that an instrument is usable but cannot support or falsify the root hypothesis.

Before collecting claim-bearing outputs, define the actual observable, normalization, fit rule, admissible current-sheet regime, plasmoid or topology diagnostic, refinement policy, and decision thresholds. Register and commission every simulator and downstream analyzer as an instrument claim under the scientific claim it serves. Freeze exact commands and analysis before fresh outcomes. Use enough distinct resistivities to identify a scaling rather than a two-point contrast, and distinguish a physical/model boundary from numerical under-resolution or an insufficient observation window.

The FLASH capability is a two-dimensional compressible single-fluid resistive-MHD application. It is appropriate for testing the classical collisional branch but cannot decide kinetic electron-scale physics. Other installed capabilities, including WarpX, are lateral instruments rather than mandatory steps: select one only when the active claim requires its closure and it can be commissioned prospectively. If the root is falsified, formulate the smallest scientifically meaningful sub-hypothesis whose domain or mechanism contains the counterexample, state a new falsifiable prediction, and challenge it with fresh evidence. Continue without asking the operator to choose parameters, and finish with a bounded supported, falsified, or honestly unresolved conclusion.
