Module property_graph 

Property Graph Engine — SQLite-backed code knowledge graph.

Stores nodes (File, Symbol, Module) and edges (imports, calls, defines, exports) extracted by deep_queries + import_resolver. Provides efficient traversal queries for impact analysis, architecture discovery, and graph-driven context loading.

Constants

GRAPH_ENGINE_VERSION

Property-graph engine generation. Bump whenever edge extraction changes (e.g. the type_ref edges that connect C#/Java same-namespace consumers to their definers, GH #398) so an existing graph built by an older engine is transparently rebuilt on the next query instead of being served without the new edges. Graphs whose graph.meta.json predates this stamp deserialize to engine version 0, so the first query after an upgrade rebuilds once.

Functions

edge_weight

Weight multiplier per edge kind for impact scoring.

engine_outdated

true when the persisted graph was built by an engine older than GRAPH_ENGINE_VERSION — or predates the version stamp entirely (missing or unreadable meta) — and must therefore be rebuilt before its edges can be trusted. Callers pair this with a node-count check: an empty graph is rebuilt regardless; a non-empty-but-outdated graph is rebuilt by this gate.

file_connectivity

Graph connectivity stats for a file: incoming/outgoing edge counts by kind.

graph_dir

Resolve the directory for graph.db and graph.meta.json.

load_meta

meta_path

related_files

Related files for a given path: direct neighbors via any structural edge, sorted by edge weight (strongest relationship first). Returns (path, weight) pairs.
