Struct GraphDescribeOutput 

pub struct GraphDescribeOutput {
    pub name: String,
    pub nodes: IndexMap<String, NodeDescribe>,
    pub edges: Vec<EdgeDescribe>,
    pub subgraphs: Vec<String>,
    pub factory: Option<String>,
    pub factory_args: Option<Value>,
}

Top-level describe() output (canonical Appendix B JSON schema).

factory + factoryArgs (R3.1.2, D285)

factory / factory_args are populated from crate::graph::GraphInner::factory / factory_args (set via crate::Graph::tag_factory). Both use skip_serializing_if = "Option::is_none" to match the pure-ts spread-conditional shape at packages/pure-ts/src/graph/graph.ts:3508-3509 — a cold describe() before any tag_factory call OMITS the factory / factoryArgs keys entirely (not serializes them as null). The pure-ts arm pins this via the "factoryArgs" in desc assertion in scenarios/graph/tag-factory.test.ts:70 (QA-A2 invariant); the Rust JSON shape converges via skip_serializing_if + rename = "factoryArgs" for the camelCase key parity.

Fields

name: String

Graph name as set at construction / mount.

nodes: IndexMap<String, NodeDescribe>

Local nodes by name.

edges: Vec<EdgeDescribe>

Local edges (dep → consumer).

subgraphs: Vec<String>

Mounted child names.

factory: Option<String>

R3.1.2 factory provenance — name set via crate::Graph::tag_factory. Omitted from JSON when None (matches pure-ts spread-conditional shape).

factory_args: Option<Value>

R3.1.2 factory args — paired with Self::factory. Omitted from JSON when None. Serialized as the factoryArgs camelCase key to match pure-ts output byte-for-byte.
