Module schema 

Graph schema — nodes, edges, kinds. Defines the Aun graph-artifact contract.

The Rust engine emits NATIVE kinds (the 9 base kinds) from day one; legacy kind strings are mapped on ingest. Unknown kinds degrade to Unknown rather than crash.

Modules

relation

The structural edge-relation vocabulary, defined ONCE so the producer (compile) and the consumers (retrieval) can’t drift on a typo’d string literal. (Typed frontmatter relations — depends_on, produces, … — live in compile::REL_FIELDS.)

Structs

Edge

A directed, evidence-bearing edge — a synapse in the knowledge graph.

EdgeEvidence

Graph

The compiled graph. (Extended graph-artifact fields — stats/aliases/built_at — are added when structure parity is wired.)

Node

A graph node. Optional fields default so partial/external JSON never panics.

RelationProfile

Retrieval/traversal semantics for a relation name.

Span

A code node’s location: the byte/line span it occupies in a source file. Doc nodes (whole-file units) carry None; Glyph symbol nodes carry Some so read_doc can return just the symbol body — every code node traceable to an exact file:line provenance span.

Enums

EdgeBasis

The provenance basis of an edge — where the evidence comes from. This is the synaptic strength signal: Resolved edges (from syntax/authoring) are trusted and strong; Lexical edges (from co-occurrence heuristics) are candidates, weak until verified.

Kind

The 9 native base kinds, plus a tolerant Unknown sink.

Constants

TRAVERSAL_ONLY_EVIDENCE

Evidence marker for a reference edge that exists PURELY as a call-graph relationship — a self.attr.method() call resolved by inferred receiver type. Such edges power callers/impact traversal but are excluded from the BM25F grounding relation-surface: a callee’s “used by X” is call structure, not “aboutness”, and including it would let a caller bleed into the callee’s grounding (and vice-versa). Single source of truth so the extractor and the scorer agree.

Functions

core_relation_profile

Return the built-in profile for one native relation.

core_relation_profiles

Built-in relation profiles for Eidos’ native graph vocabulary.
