Graph
Opt-in capability for querying the entity-relationship axis of the knowledge graph: neighbourhoods, paths between entities, and the provenance lineage behind a single proposition.
This is distinct from GraphTraversalCapable, which navigates the proposition abstraction hierarchy (source/derived links). This fragment treats entities as nodes and propositions that mention two resolved entities as edges.
All methods have default bodies that return empty results, making this a pure override seam for graph-native backends. The portable facade builds equivalent results store-agnostically and only routes here when the store declares this capability.

The entity neighbourhood reachable from entityId, confined to contextId (a null context is unscoped — exactly the plain neighborhood overload).
The entity neighbourhood reachable from entityId, keeping only edges whose source authority is at least minAuthority (a null floor keeps everything).
Same as the context-scoped overload above, but also carries the caller's own depth ceiling (maxDepth) so a backend that enforces its own hard cap on the walk can clamp against the caller's ceiling instead of a value it hardcodes itself. The facade always calls this overload (passing its own configured maxDepth) rather than the three-arg one, so a store that only overrides the three-arg overload keeps working unchanged — it just never sees the caller's ceiling and falls back to whatever bound it enforces on its own.
The paths connecting entityIdA to entityIdB, confined to contextId (a null context is unscoped — exactly the plain pathBetween overload). Routed here only when honorsContextFilter is true; the default body delegates to the unscoped overload.
The paths connecting entityIdA to entityIdB, keeping only edges whose source authority is at least minAuthority (a null floor keeps everything).
Same as the context-scoped overload above, but also carries the caller's own hop ceiling (maxDepth) for the walk, so a backend that enforces its own hard cap can clamp against the caller's ceiling instead of a value it hardcodes itself — mirroring the maxDepth-carrying neighborhood overload. The facade always calls this overload rather than the three-arg one, so a store that only overrides the three-arg overload keeps working unchanged, just without seeing the caller's ceiling.
The lineage behind the proposition with the given id, assembled from its durable fields.
The lineage behind propositionId, confined to contextId: a proposition in another context is treated as absent (null). A null context is unscoped — exactly the plain whyExplain overload. Routed here only when honorsContextFilter is true; the default body delegates to the unscoped overload.
