Abstract
A bstract An amplitude analysis of the Cabibbo-favored decay D + → K − π + π + π 0 is performed, using 7.93 fb − 1 of e + e − collision data collected with the BESIII detector at the center-of-mass energy of 3.773 GeV. The branching fractions of the intermediate processes are measured, with the dominant contribution $$ {D}^{+}\to {\overline{K}}^{\ast }{(892)}^0\rho {(770)}^{+} $$ D + → K ¯ ∗ 892 0 ρ 770 + observed to have a branching fraction of (4.35 ± 0.07 stat . ± 0.17 syst . )%. With the detection efficiency derived from the amplitude analysis, the absolute branching fraction of D + → K − π + π + π 0 is measured to be (6.35 ± 0.04 stat . ± 0.07 syst . )%.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
