Detailed Description

Per-node data collected by routing observations through the tree.

For internal (condition) nodes:

• projected_values: dot product of each reaching observation with the node's projector vector.
• groups: group label (1-indexed response) of each reaching observation, parallel to projected_values.
• projector, threshold: the split parameters (copied for convenience so the R side can render histograms without re-accessing the tree).

For leaf (response) nodes:

• projected_values is empty.
• groups contains labels of observations reaching the leaf.
• value is the predicted group (0-indexed response).
