### P1 — match diagram naming (labels only, no schema change) - "Inlet Elevation" → "Inlet (bottom of pipe, m)" - "Outlet Elevation" → "Outlet (top of pipe, m)" - "Overflow Level" → "Overflow (weir crest, m)" - "Basin Bottom (m Refheight)" → "Basin floor above datum (m)" - Added a one-line banner at the top of Basin Geometry: "All heights measured from the basin floor (0 m)." These map directly to the clarifications added to basin-model.drawio.svg so editor and diagram speak the same vocabulary. ### P3 — live derived safety levels next to the % fields Low/High Volume Threshold fields now show the resulting trip level live as the operator types: Low Volume Threshold (%) [ 2 ] → dryRunLevel ≈ 0.21 m High Volume Threshold (%) [ 98 ] → overfillLevel ≈ 4.41 m Recomputed on every input/change of outflowLevel, inflowLevel, overflowLevel, minHeightBasedOn, or either %. Pure UI feedback — no schema change, no save-side change, same formulas as specificClass._validateThresholdOrdering(). Also includes the user's latest basin-model.drawio.svg update (inlet=bottom/outlet=top labels + datum annotation). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
