Hierarchy-aware top-down classifier that always emits a valid taxonomy path
This baseline trains one logistic decision at each internal taxonomy node and traverses the training-fold taxonomy tree top-down at inference time. It is hierarchy-aware by construction and always returns a valid taxonomy leaf from the training tree.
