KG Integration + Zustand Store Implementation - COMPLETE

Date: 2025-11-03 Status: ✅ COMPLETE - 7 files modified, all integrations tested Session Duration: ~2 hours

Overview

This session completed two major integration tasks: 1. KGClient Integration: Integrated production-ready Knowledge Graph client into 3 backend services 2. Zustand Store Implementation: Implemented complete Workflow and Agent state management for UI

Part 1: KGClient Integration (Backend)

Services Integrated

1. MOA Workflow Enrich Function

File: src/moa/workflows/clean_map_enrich_workflow.py

Before:

async def enrich(payload: Dict[str, Any]) -> Dict[str, Any]:
    # TODO: implement lookups (KG, 3P data)
    return {"status": "ok", "stage": "enrich", "count": len(payload.get("items", []))}

After: - ✅ Full KG integration for data enrichment - ✅ Dynamic query building based on item attributes (vendor, product_id, customer_id) - ✅ Enriches items with KG matches, confidence scores, and hit counts - ✅ Error handling with graceful fallback - ✅ Returns enrichment statistics

Example Enrichment:

enriched_item = {
    **original_item,
    "kg_enrichment": {
        "matched": True,
        "count": 5,
        "top_match": {"id": "vendor_123", "score": 0.92},
        "confidence": 0.92
    }
}

2. Cell 25 Causal Journey Integration

File: src/cells/cell25/causal_journey_integration.py

Before:

# TODO: In production, call Cell 3 API to actually update Neo4j edge weights
# async with httpx.AsyncClient() as client:
#     await client.post(f"{CELL3_KG_URL}/api/v1/kg/bulk-update-edge-weights", ...)

After: - ✅ Production-ready KG edge weight updates - ✅ Bulk edge weight update operation with CATE-based adjustments - ✅ Metadata tracking (campaign_id, updated_by, CATE values) - ✅ Success/failure tracking in response - ✅ Error handling with warning logs

Example Edge Update:

kg_update_request = {
    "operation": "bulk_update_edge_weights",
    "updates": [
        {
            "edge_id": "edge_123",
            "new_weight": 0.85,
            "metadata": {
                "cate": 0.35,
                "weight_adjustment": 0.35,
                "campaign_id": "camp_456",
                "updated_by": "cell25_causal_integration"
            }
        }
    ]
}

3. Cell 15 Personalization API

File: src/cells/cell15/personalization_api.py

Before: - No KG enrichment for user profiles - Static profile creation

After: - ✅ KGClient integrated into PersonalizationEngine - ✅ New method: _enrich_profile_with_kg() - ✅ Automatic KG enrichment on new profile creation - ✅ Enriches: preferences, interests, segments, demographics - ✅ Error handling with warning logs

Example Profile Enrichment:

# Before: Empty profile
profile = UserProfile(user_id="user_123")

# After KG enrichment:
profile = {
    "user_id": "user_123",
    "preferences": {"technology": 0.8, "electronics": 0.9},  # From KG
    "interests": ["ml", "ai", "gadgets"],                    # From KG
    "segments": ["tech_enthusiast", "audiophile"],           # From KG
    "demographics": {"age": 28, "location": "US"}            # From KG
}

Part 2: Zustand Store Implementation (Frontend)

Store Slices Implemented

1. Workflow Slice

File: miz-oki-command-center-ui/store/slices/workflowSlice.ts (126 lines)

Interface:

interface Workflow {
  id: string;
  name: string;
  status: 'running' | 'paused' | 'completed';
  updatedAt: string;
  description?: string;
  steps?: Array<{
    id: string;
    name: string;
    status: 'pending' | 'running' | 'completed' | 'failed';
  }>;
}

interface WorkflowSlice {
  workflows: Workflow[];
  activeWorkflowId?: string;
  setActiveWorkflow: (id: string | undefined) => void;
  fetchWorkflows: () => Promise<void>;
  updateWorkflow: (id: string, updates: Partial<Workflow>) => void;
  refreshWorkflowStatus: (id: string) => Promise<void>;
  createWorkflow: (workflow: Omit<Workflow, 'id'>) => Promise<Workflow>;
  deleteWorkflow: (id: string) => Promise<void>;
}

Features: - Complete CRUD operations - Active workflow tracking - Status refresh from API - Error handling for all async operations

2. Agent Slice

File: miz-oki-command-center-ui/store/slices/agentSlice.ts (122 lines)

Interface:

interface Agent {
  id: string;
  name: string;
  state: 'idle' | 'busy' | 'error';
  type?: 'moa' | 'moe' | 'cell' | 'specialist';
  description?: string;
  capabilities?: string[];
  metrics?: {
    tasksCompleted: number;
    successRate: number;
    avgResponseTime: number;
  };
}

interface AgentSlice {
  agents: Agent[];
  selectedAgentId?: string;
  fetchAgents: () => Promise<void>;
  updateAgent: (id: string, updates: Partial<Agent>) => void;
  getAgentById: (id: string) => Agent | undefined;
  setSelectedAgent: (id: string | undefined) => void;
  refreshAgentStatus: (id: string) => Promise<void>;
  executeAgentTask: (id: string, task: any) => Promise<any>;
}

Features: - Agent state management (idle/busy/error) - Task execution with automatic state transitions - Agent metrics tracking - Selected agent tracking - Error handling with automatic error state

3. Provider Integration

File: miz-oki-command-center-ui/app/providers.tsx

Changes Made:

// Before:
// TODO: Implement updateWorkflow in store
// store.updateWorkflow(data.workflowId, data.updates);

// TODO: Implement fetchWorkflows and fetchAgents in store
// store.fetchWorkflows();
// store.fetchAgents();

// After:
store.updateWorkflow(data.workflowId, data.updates);
store.updateAgent(data.agentId, data.updates);
store.fetchWorkflows();
store.fetchAgents();
store.refreshWorkflowStatus(activeWorkflowId);
store.refreshAgentStatus(selectedAgentId);

Features Wired: - ✅ SSE event handlers for workflow_update and agent_update - ✅ Initial data fetching on mount - ✅ Periodic refresh (30s interval) for active items - ✅ Cleanup on unmount

KG Query Examples

1. MOA Workflow - Enrich Vendor Data

kg_result = await kg_client.query({
    "node": "vendor",
    "filters": {"name": "Google"},
    "limit": 5
})

2. Cell 25 - Update Edge Weights with CATE Data

kg_result = await kg_client.query({
    "operation": "update_edges",
    "data": {
        "updates": [
            {
                "edge_id": "edge_123",
                "new_weight": 0.85,
                "metadata": {...}
            }
        ]
    }
})

3. Cell 15 - Enrich Customer Profile

kg_result = await kg_client.query({
    "node": "customer",
    "filters": {"id": "user_123"},
    "include_edges": True,
    "limit": 10
})

Zustand Store Usage in React

Example Component

import { useStore } from '@/store';
import { useEffect } from 'react';

function WorkflowDashboard() {
  const workflows = useStore((state) => state.workflows);
  const activeWorkflowId = useStore((state) => state.activeWorkflowId);
  const setActiveWorkflow = useStore((state) => state.setActiveWorkflow);
  const fetchWorkflows = useStore((state) => state.fetchWorkflows);

  useEffect(() => {
    fetchWorkflows();
  }, [fetchWorkflows]);

  return (
    <div>
      {workflows.map(w => (
        <div
          key={w.id}
          onClick={() => setActiveWorkflow(w.id)}
          className={activeWorkflowId === w.id ? 'active' : ''}
        >
          {w.name} - {w.status}
        </div>
      ))}
    </div>
  );
}

Agent Execution Example

function AgentExecutor() {
  const executeAgentTask = useStore((state) => state.executeAgentTask);
  const agents = useStore((state) => state.agents);

  const handleExecute = async (agentId: string, task: any) => {
    try {
      const result = await executeAgentTask(agentId, task);
      console.log('Task result:', result);
    } catch (error) {
      console.error('Task failed:', error);
    }
  };

  return (
    <div>
      {agents.map(agent => (
        <button
          key={agent.id}
          onClick={() => handleExecute(agent.id, {type: 'analyze'})}
          disabled={agent.state === 'busy'}
        >
          {agent.name} - {agent.state}
        </button>
      ))}
    </div>
  );
}
