Module semantic 

Common semantic facts every lane that has a document publishes — plus engine-specific extensions for richer protocol-native shape.

Hekate’s indexing / search / preview pipeline consumes SemanticQuery only — uniform across lanes. Apparatus’s inspector pane can downcast to a lane-specific extension when present (e.g., if let Some(html) = doc.as_html_ext()).

Cf. Hekate doc §“Semantic Plane”. Per Mark’s correction: don’t force one fake tree model across lanes — use common-minimum + engine-specific extensions instead.

Structs

AnchorInfo

One named anchor (target of #fragment navigation).

HeadingInfo

One heading and its level.

LinkInfo

One outbound link.

Enums

SemanticRole

Generic semantic role consumers can ask about, independent of any specific markup language. Map onto each lane’s native vocabulary.

Traits

SemanticQuery

Common-minimum semantic queries every lane with a document publishes. The trait is generic over NodeId so consumers that hold a concrete impl can index without boxing; engine-agnostic dispatch (Hekate) reads SourceNodeId via the inferred as_source_id helper each impl defines.
