Summary: Testing whether stripe-correlated feed-rate disorder creates a more defect-rich mixed phase in the Gray-Scott reaction-diffusion model.

The Gray-Scott model supports spots, stripes, and mixed states depending on how reaction and feed parameters are tuned. This experiment asks whether making the feed rate spatially stripe-correlated near the spot-stripe boundary can increase defect richness and pattern complexity beyond what appears under IID disorder or very strong banding.

The simulation varies the spatial organization of feed disorder rather than only its magnitude. Intermediate striping is expected to frustrate clean domain formation, producing a mixed phase with more interfaces and a broader range of local pattern motifs.

That makes the problem about geometry-driven complexity in a standard nonlinear pattern-forming system. The output tests whether structured heterogeneity can stabilize a visually and dynamically richer regime.

Method: Reaction-diffusion simulations of the Gray-Scott model with stripe-correlated feed-rate disorder near the spot-stripe boundary.

What is measured: Interface density, spectral entropy, defect richness, and dependence on stripe correlation versus IID and strongly banded disorder.
