Review Rainwater Storage in a Horizontal Tank

Calculate horizontal tank contents from fill depth,then review one supplied rainfall event collection,storage and overflow with both complete reports.

• Choose JSON with exactly diameterMetres,lengthMetres,fillDepthMetres as numeric STRING fields. Level flat-ended horizontal cylinder;metres,depth0 todiameter. Source4KiB/1024units;fields single-line128units. Enter projected HORIZONTAL catchment area,event rainfall,runoff fraction and discarded first-flush litres. Capacity is actual native capacityM3*1000;current contents use actual native liquidLitres. No rounding,capacity/current override or freeboard deduction. Invalid event assumptions or derived litre bounds keep the full tank checkpoint. Full source,arguments and both reports stay unredacted in six ZIP members. ZIP256KiB/expanded128KiB/member64KiB. No dished heads,tilt,calibration,weather lookup,demand,continuous routing,leaks,evaporation,annual reliability,potability,treatment,structural,overfill or flood-safety recommendation. Supplied-event model only. Original30sworkers;90sconsumer.
• Read actual full original tank report after unchanged whole-checkpoint association verification. Capacity input=String(actual result.capacityM3*1000) using one explicit binary64 m3-to-L multiplication. Current input=String(actual result.liquidLitres),the native already-converted field;do not rederive current from geometry or clamp it. These actual capacity/current arguments plus supplied area/rain/coefficient/flush strings feed original rainwater. Record full native operands,the1000factor,operation and both argument strings;no rounding/capacity override/current override/freeboard subtraction. Original range mismatch keeps full CP and refuses. The capacity and current are geometric model estimates,not calibrated measurements.
• Original nonnegative area,rain,flush,capacity0..1e12,coefficient0..1,current0..actual capacity. RoofRunoff=area*rain*coefficient in sequential binary64 order;discarded=min(runoff,flush),capturable=max(0,runoff-flush),free=capacity-current,stored=min(capturable,free),overflow=capturable-stored,final=current+stored. Preserve all13nativefields exactly,including zero/negativezero normalization. No exact-rational reassociation,clamping to artificial headroom or simplifying final to capacity. Empty/tiny tanks valid when original bounds allow;oversized tank litres refuse with full CP.
