Description

Make sure eta is not applied in base. Need to handle stump correctly.

Contributor guide

Research direction

The issue names no file or test. Start by locating the C++ code that computes base weights for leaf nodes and handles stumps, then trace how eta is applied in each path. Identify the existing tests for these cases and confirm that completion means eta is excluded from the base while stump handling remains correct.
