# SOURCE-BUILT lib_lightgbm 4.6 (VERSION 4.6.0.99) CPU-only single-thread: the
# regression_l1 + bagging tree-0 is a CONSTANT (no-split) tree, leaf_value = 11.0
# (the label median), leaf_count = 12. The prior "rust:0.0 vs cpp:11.0" gap was a
# leaf-VALUE divergence on this constant tree: C++ applies the
# ObtainAutomaticInitialScore fallback (gbdt.cpp:418-429) even with
# boost_from_average=false, using the label median as the no-split tree's leaf value;
# the Rust port pushed 0.0. FIXED in gbdt::no_split_constant_value (D-05 faithful-fix).
# regression_l1 + bagging is now UN-DEFERRED and asserts real-binary parity.
# See 07-D05-DECISION.md.
