- ItemManager(uint seed, ...) refuses seed 0 and seeds Random from it.
- RunStart.ItemSeed(galaxy, step) is public (formula unchanged), refuses a
zero result; named steps ArenaStep, StageStep, ContinueStep and NoRunSeed.
- Continue seeds the item stream from the saved run's seed (ContinueStep);
a scene with no galaxy uses NoRunSeed.
- Zone's unpack scatter draws SimulationDice.For(CombatSeed, ScatterStream,
1-based pack ordinal), never the item stream.
- Loadout's scratch manager and AetherDb's catalog command take fixed seeds;
every test and Editor construction gains 1u (mechanical rewrite).

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.

- 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.

The probe steps a Zone, lowers its flow through VolumeSampling.LowerFlow, dispatches the HLSL
globalFlow and slopeFlow, and compares with FlowField (max error 1.0e-4 of amplitude, tolerance
1e-3). All commits build; the Unity side was verified from this tree.
