FlowFieldSceneVerify opens ARPG.unity before anything touches the project's types, drives VolumeSampling and Stardust Start/Update with a zone attached, and asserts no exception or logged error, FLOW_GLOBAL and FLOW_SLOPE enabled, _FlowAmplitude non-zero, the stardust buffer changing with the flow and freezing with a paused zone, the noise clock, and CloudShader pass 0 carrying the FLOW_* keywords. FlowFieldParityVerify now binds a ramp height so FLOW_SLOPE and its pragma matter, and checks the noise follows _NebulaNoiseTime. The mutation harness runs both checks, with six new mutants.
