Abstract
Abstract An adult male skeleton from the early Neolithic cemetery of Shamanka II on the south coast of Lake Baikal (Siberia, Russia) presents one of most striking examples of upper limb bilateral asymmetry documented without obvious indicators of skeletal pathology or trauma to the afflicted arm. The condition is noteworthy not only for its severity, with asymmetry values as high as 89.5%, but also for its involvement of the whole upper extremity, from clavicle to manual phalanges. The lack of any demonstrable hypertrophy on the unaffected left arm, and the clear evidence of extensive hypotrophy/atrophy on the right, leave little doubt that this asymmetry has a pathological or traumatic basis rather than a functional (activity‐induced) one. It most likely reflects paralysis or paresis of the entire right arm resulting from complete brachial palsy incurred prior to the attainment of skeletal maturity in that limb.

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
