Struct GrainCoverage 

pub struct GrainCoverage {
    pub denominator: DenominatorBasis,
    pub covered_artifacts: usize,
    pub describing_entities: usize,
    pub unit: &'static str,
    pub direct_covered: usize,
    pub tree_only_covered: usize,
    pub uncovered: Vec<String>,
    pub excluded: usize,
    pub tree_anchors: Vec<TreeFanout>,
}

Grain-classed coverage over S(D) (B1). Tree-anchor fan-out is a separate axis — direct_covered and tree_only_covered are never summed into one blended percentage.

Fields

denominator: DenominatorBasis

The denominator basis (B5).

covered_artifacts: usize

S(D) artifacts covered by at least one describing entity, direct or tree — the coverage unit (2026-09-02, basket line 7): an artifact counts once however many anchor rows or entities describe it, so three anchors from one entity on one file are one covered artifact.

describing_entities: usize

Distinct destination entities that describe at least one S(D) artifact through this binding’s anchors.

unit: &'static str

The unit statement, verbatim on the report, so the figure is never read as an anchor-row count.

direct_covered: usize

S(D) files directly covered by a non-tree (file / span) anchor.

tree_only_covered: usize

S(D) files covered only via a tree-grain anchor (the fan-out axis, kept distinct from direct_covered).

uncovered: Vec<String>

S(D) files with no anchor at all (the heavy artifact list).

excluded: usize

In-scope artifacts carrying no anchor that a projection exclude declared out of intent, and which are therefore NOT in uncovered (C7). Dropped rather than marked: a reader counts the array and a gate reads it, so an entry left in it stays owed however it is annotated. The rationales ride disposed_excluded_rationales on the report.

tree_anchors: Vec<TreeFanout>

Per tree anchor, its fan-out over S(D) (the heavy detail list).
