Abstract
A pseudomonotone operator serves to study the dynamic network equilibrium of the French dairy industry. Using a modified variational inequality model, which is based on the price variations, we reverse the typical problem formulation and claim that the absence of synchronization between the variations, which also need to be proportionate, is what causes the network disequilibrium. Provided the pseudomonotonicity of the mapping, the solution of the variational inequality problem also happens to be a fixed point. The model outputs show that the economic viability of the upstream agents is in conflict with the overall network equilibrium. The results further suggest that increasing the threshold of resale-below-cost should enlarge the asynchronicity between the upstream and instream price adjustments, which is problematic because the price variations are already asymmetric at the levels of upstream and downstream layers. The best path toward the network equilibrium would go by carrying out a further integration of the upstream layer.

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
