 - the Scoliosis1K raw pose data does not appear obviously broken
 - the OpenGait training/evaluation infrastructure is not the main problem
 - PAV computation is not the main blocker
+- the skeleton branch is learnable on the easier `1:1:2` split
+- on `1:1:2`, `body-only + weighted CE` reached `81.82 Acc / 66.21 Prec / 88.50 Rec / 65.96 F1` on the full test set
+- on the same split, `body-only + plain CE` improved that further to `83.16 Acc / 68.24 Prec / 80.02 Rec / 68.47 F1` at `7000`

 ### Not reproducible with current evidence

@@ -171,6 +174,8 @@ Conclusion:
 - the papers are probably directionally correct
 - but the skeleton-map and DRF pipelines are under-specified
 - the missing implementation details are important enough that a faithful independent reproduction is not currently achievable from the paper text and released materials alone
+- the `1:1:8` class ratio is not just a nuisance; it appears to be a major driver of the current skeleton/DRF failure mode
+- on the easier `1:1:2` split, weighted CE is not currently the winning recipe; the best local full-test result so far came from plain CE
