- 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. Not built or run when committed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
