Abstract
We present results for the elliptic and triangular flow coefficients ${v}_{2}$ and ${v}_{3}$ in $\mathrm{Au}+\mathrm{Au}$ collisions at $\sqrt{s}=200\text{ }\text{ }A\mathrm{GeV}$ using event-by-event $\mathrm{D}=3+1$ viscous hydrodynamic simulations. We study the effect of initial state fluctuations and finite viscosities on the flow coefficients ${v}_{2}$ and ${v}_{3}$ as functions of transverse momentum and pseudorapidity. Fluctuations are essential to reproduce the measured centrality dependence of elliptic flow. We argue that simultaneous measurements of ${v}_{2}$ and ${v}_{3}$ can determine $\ensuremath{\eta}/s$ more precisely.

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
