Abstract
A flow composed of two populations of pedestrians moving in different directions is modeled by a two-dimen\-sional system ofconvection-diffusion equations. An efficient simulation of the two-dimensional model is obtained by a finite-volume scheme combinedwith a fully adaptive multiresolution strategy. Numerical tests showthe flow behavior in various settings of initial and boundaryconditions, where different species move in countercurrent orperpendicular directions.The equations are characterized ashyperbolic-elliptic degenerate, with an elliptic region in the phase space, which in one space dimension is known to produce oscillation waves.When the initial data are chosen inside the elliptic region,a spatial segregation of the populations leads to pattern formation.The entries of the diffusion-matrix determine the stability of the model and the shape of the patterns.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
