tree-models

Use this sub-skill for causal trees, uplift trees, tree ensembles, tree plots, and tree persistence.

Route here when the request is about

• CausalTreeRegressor or CausalRandomForestRegressor
• UpliftTreeClassifier or UpliftRandomForestClassifier
• tree visualization or tree-string rendering
• save / load for tree models
• compiled-extension or tree-import failures

Guardrails

• CausalRandomForestRegressor has no fit_predict; use fit(...) and then predict(...).
• UpliftTreeClassifier uses fill(...) and prune(...) for validation-set updates.
• uplift_tree_string(...) prints the ASCII tree, and uplift_tree_plot(...) returns a graph object.
• Keep class-specific persistence, visualization, and failure-handling details in the bundled references.
