WebSocket Streaming

Real-time bidirectional communication between DAG execution engines and dashboards. Typed event protocols, connection management, and React hook integration.

When to Use

✅ Use for:

• Streaming DAG node state changes to a visualization dashboard
• Sending human gate decisions from dashboard to execution engine
• Live cost ticker and progress updates during execution
• Bi-directional communication (not just server → client)

❌ NOT for:

• One-way server → client updates (consider SSE, simpler)
• REST API design (use api-architect)
• Polling-based status checks (WebSocket replaces polling)
