- VolumeSampling registers FLOW_GLOBAL / FLOW_SLOPE with GlobalKeyword.Create (the constructor only looks up).
- FlowField.Scroll folds each Tri3D octave's phase modulo 1 in double (float2, [0,1)); Zone.Flow evaluates at Zone.FlowScroll.
- FlowField.Cycle: the nebula's flow cycle and Stardust's particle lifetime phase come from zone time (_FlowCycle, phase uniform), not _Time.y / Time.time.
- FlowFieldParityVerify reaches the keyword-gated flow(), fails on logged errors, tolerance 3e-4; mutants updated.
