N8N-Style Workflows

Overview

• Workflows can be declared with nodes and connections, modeled after n8n.
• Each node maps to a C++ workflow plugin (via plugin or type).
• Connections define execution order. When connections are omitted, the node array order is used.

Node Shape

• id or name: required. Used to identify the node in connections.
• plugin or type: required. The plugin string must match a registered step.
• inputs / outputs: optional string maps for workflow context keys.
• position: optional [x, y] array for layout parity with n8n.

Connections Shape

{
  "connections": {
    "load_config": {
      "main": [
        [
          { "node": "validate_schema", "type": "main", "index": 0 }
        ]
      ]
    }
  }
}

Templates

• config/workflows/templates/boot_default.json and config/workflows/templates/frame_default.json are n8n-style now.
• config/workflows/templates/n8n_skeleton.json is a minimal starting point.

Generic Steps

• Implementations live in src/services/impl/workflow/workflow_generic_steps/.
• Full catalog lives in ROADMAP.md under "Generic Step Catalog (Implemented)".
