Struct EntityAnchorComposition 

Source 
pub struct EntityAnchorComposition {
    pub by_class: BTreeMap<String, usize>,
    pub by_grain: BTreeMap<String, usize>,
    pub derived_inputs: Vec<Vec<String>>,
    pub tree_grain_artifacts: Vec<String>,
}
Expand description

Per-entity provenance-class + grain composition, computed from an entity’s anchor list. Tree-grain fan-out is surfaced distinctly so a single entity anchored to a large tree is never laundered into full per-file credit — the count of tree anchors is visible on its own axis, and downstream (E3b) reads the fan-out counts from resolution.

Fields§

§by_class: BTreeMap<String, usize>

Anchor count keyed by provenance-class wire string.

§by_grain: BTreeMap<String, usize>

Anchor count keyed by grain wire string.

§derived_inputs: Vec<Vec<String>>

The derived_from input lists of every derived anchor, in anchor order — E3b’s derived-input provenance.

§tree_grain_artifacts: Vec<String>

Artifact refs of every tree-grain anchor — the fan-out axis. A tree anchor is one row here regardless of how many files the tree contains; the file count is an observation resolution supplies, not a credit this composition grants.
