Module def 

Serializable graph definitions — the GUI / n8n-enabler.

A GraphDef fully describes a graph as data: nodes (with stable string ids, opaque consumer-owned config blobs, and inert GUI layout positions), edges (with declarative conditions and loop budgets), and explicit entries. The fluent BspGraph builder remains the authoring API; definitions are the interchange format, and def -> graph -> def is a fixed point (modulo Custom closures, which serialize as their label only and fail closed at instantiation unless the label is re-registered as a named condition).

version has existed since the first serialized file: bump GRAPH_DEF_VERSION on any breaking format change so old files are never unmarked.

Structs

EdgeDef

A serializable edge definition.

GraphDef

A fully serializable graph description.

NodeDef

A serializable node definition.

StaticInputDef

A serializable static input: an initial pin value injected before execution.

Enums

ActivationDef

Serializable activation policy: "any" (control-flow default) or "all" (join).

ConditionDef

The serializable condition subset.

RecoveryDef

Serializable recovery policy: "fail_fast", "error_edge", or {"retry": {...}} (backoff parameters only — classification never serializes).

Constants

GRAPH_DEF_VERSION

The current GraphDef schema version. Bump on any breaking format change.
