  "interpretation": "A difference in flow between maintained external-field-on and otherwise identical field-off controls can establish a conditional magnetic response. No bow-shock claim without additional shock-frame, jump-condition and model-validity checks. The source-off control is prescribed-inflow with all imposed device fields removed; it is not a physical shot with only the coil disabled.",
  "mesh_control_note": "A native 1 mm import preserved the front field but failed the wider buffered-field gate (14.9% vector error), so it was rejected before plasma dynamics. Prepare a 0.4 mm field transfer and use it for a prospective refinement comparison against 0.5 mm. This extension was written before any 0.4 mm import or dynamics result.",
  "mesh_estimator_detail": "For grid comparisons use a fixed x=-7.25 mm plane and an exact 6 x 6 mm footprint, with fractional edge-cell areas and linear interpolation of integrated moments between neighboring x cell centers. This equals the original h=0.5 mm plane metric and avoids changing the physical comparison surface on the h=0.4 mm mesh. The flux estimator is positive cell-mean (bulk) mass flux, not a distribution-resolved one-way particle flux. Added before any h=0.4 mm dynamics.",

    "reporting": "Keep requested-window execution status separate from common-window finite-output/readout status. A timeout is not silently converted to successful 220 ns completion."
