description	Build and debug ADK graph workflows with checkpoints, routing, interrupts, and state reducers. Use when implementing graph-based orchestration in adk-graph.

ADK Rust Graph Orchestration

Overview

Use StateGraph for explicit state channels and deterministic routing.

Workflow

1. Define schema channels and reducer semantics.
2. Add nodes and explicit entry/exit edges.
3. Add conditional routes with explicit targets.
4. Add checkpoint/interrupt behavior only after base flow is stable.
5. Verify recursion limits and stop conditions.

Guardrails

1. Validate every edge target against known nodes.
2. Keep routing keys small and deterministic.
3. Emit structured events for stream-mode debugging.
