Abstract
A new charm-strange meson, the ${D}_{s1}^{*}(2863)$, has recently been observed by the LHCb Collaboration which also determined the ${D}_{sJ}^{*}(2860)$ to have spin 3. One of the speculations about the previously observed ${D}_{s1}^{*}(2710)$ is that it is the $1{^{3}D}_{1}(c\overline{s})$ state. In this paper we reexamine the quark model properties and assignments of these three states in light of these new measurements. We conclude that the ${D}_{s1}^{*}(2863)$ and ${D}_{s3}^{*}(2863)$ are the $1{^{3}D}_{1}(c\overline{s})$ and $1{^{3}D}_{3}(c\overline{s})$ states respectively and the ${D}_{s1}^{*}(2710)$ is the $2{^{3}S}_{1}(c\overline{s})$ state. In addition to these three states there are another three excited ${D}_{s}$ states in this mass region still to be found, the $2{^{1}S}_{0}$ and two $1{D}_{2}$ states. We calculate the properties of these states and expect that LHCb has the capability of observing these states in the near future.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
