Core domain types for WorldInterface.

This crate defines the foundational types shared across all WI crates:

• Identity types (id::FlowId, id::FlowRunId, id::NodeId, id::StepRunId)
• FlowSpec model (declarative workflow graph) — flowspec::FlowSpec
• Connector descriptors — descriptor::Descriptor
• Receipt artifacts — receipt::Receipt

worldinterface-core has no dependency on ActionQueue. It is a pure domain model crate.

worldinterface-core

Core domain types for WorldInterface: FlowSpec, IDs, Descriptor, Receipt.

Overview

This crate defines the foundational types used throughout WorldInterface with no ActionQueue dependency and no I/O:

• id -- Strongly-typed UUID identifiers (FlowId, FlowRunId, NodeId, StepRunId)
• flowspec -- Declarative workflow graph model (FlowSpec, Node, NodeType, Edge)
• descriptor -- Connector self-description with input/output schemas
• receipt -- Immutable content-addressed evidence of boundary crossings
• metrics -- MetricsRecorder trait for cross-crate instrumentation

Node Types

ConnectorNode  -- External boundary crossing (HTTP, filesystem, etc.)
TransformNode  -- Pure data transformation (identity, field mapping)
BranchNode     -- Conditional routing (equals, extensible)
