Module packed 

12-byte packed node format and ensemble binary layout.

Binary Format

[EnsembleHeader: 16 bytes]
[TreeEntry × n_trees: 8 bytes each]
[PackedNode × total_nodes: 12 bytes each]

Learning rate is baked into leaf values at export time, eliminating one multiply per tree during inference.

Structs

EnsembleHeader

Header for the packed ensemble binary format. 16 bytes, 4-byte aligned.

PackedNode

12-byte packed decision tree node. AoS layout for cache-optimal inference.

TreeEntry

Tree table entry: metadata for one tree in the ensemble. 8 bytes.
