Struct KgQueryNode 

pub struct KgQueryNode {
    pub target_id: String,
    pub relation: String,
    pub valid_from: Option<String>,
    pub valid_until: Option<String>,
    pub observed_by: Option<String>,
    pub title: String,
    pub target_namespace: String,
    pub depth: usize,
    pub path: String,
}

One node returned by db::kg_query (Pillar 2 / Stream C — memory_kg_query). Each node represents a memory reachable from the query’s source through one outbound link, carrying the link’s temporal-validity columns plus the target memory’s display fields and the traversal path. depth is the actual number of hops from the source (1..=KG_QUERY_MAX_SUPPORTED_DEPTH); path is the src->mid->target chain as discovered by the recursive CTE.

Fields

target_id: String

relation: String

valid_from: Option<String>

valid_until: Option<String>

observed_by: Option<String>

title: String

target_namespace: String

depth: usize

path: String
