Abstract
By using a single formalism to handle charm, strange, and light valence quarks in full lattice QCD for the first time, we are able to determine ratios of quark masses to 1%. For ${m}_{c}/{m}_{s}$ we obtain 11.85(16), an order of magnitude more precise than the current PDG average. Combined with 1% determinations of the charm quark mass now possible this gives ${\overline{m}}_{s}(2\text{ }\text{ }\mathrm{GeV})=92.4(1.5)\text{ }\text{ }\mathrm{MeV}$. The MILC result for ${m}_{s}/{m}_{l}=27.2(3)$ yields ${\overline{m}}_{l}(2\text{ }\text{ }\mathrm{GeV})=3.40(7)\text{ }\text{ }\mathrm{MeV}$ for the average of $u$ and $d$ quark masses.

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
