Prepare their positions as input data. A wave-sampling job writes a height array, while an independent wind-sampling job writes a wind array. Both can read the position array; neither producer should overwrite the other's output.\n\nCombine their handles with `JobHandle.CombineDependencies`, then pass the combined handle when scheduling a force-calculation job that reads both results. The combination means that the consumer waits for both producers. It does not force the producers to execute simultaneously, and their scheduling order alone would not establish the required dependency. These names and the buoy count describe a proposed project design.
