Abstract
In this work, we prove existence local entropy solution of a convection-diffusion type integro-differential equation \displaystyle \partial_{t}\bigg(k* (j(v)-j(v_{0}))\bigg) - \nabla\cdot\bigg( a(x,\nabla \varphi (v))+ F(\varphi (v))\bigg) = f in $Q_{T}:= (0,T) \times \Omega$ with Dirichlet boundary condition $v(0, \cdot{})= v_{0}$ in $\Omega$ and $L^{1}$-data $f \in L^{1}((0,T)\times \Omega), \ j(v_{0})\in L^{1}(\Omega)$. To that end, regularising the data by $L^{\infty}$-functions, using the existence result of entropy solution for these more approximate data and a comparison and diagonal principle of the regularised entropy solution, we prove the existence of an local entropy solution.

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
