+# PHASE 2: PRODUCTION DEPLOYMENT & FRONTEND INTEGRATION
+## Strategic Plan - AGENTS.md Compliant
+
+**Date:** 2026-08-04 15:40 KST  
+**Status:** PREPARATION COMPLETE - READY FOR EXECUTION  
+**Authority:** AGENTS.md v16.0

+
+## 🎯 Integration Analysis
+
+### Current State (Development)
+```
+Frontend:  http://localhost:3000
+API:       http://localhost:5000
+Proxy:     vite.config.ts → '/api' → 'http://localhost:5000'
+```
+
+### Target State (Production)
+```
+Frontend:  https://kartsell.taxbaik.com
+API:       https://api.kartsell.taxbaik.com
+Proxy:     vite.config.ts → '/api' → 'https://api.kartsell.taxbaik.com'
+```
+
+### Integration Points Found
+```
+✅ frontend/src/shared/api/client.ts
+   - Axios client with baseURL: '/api'
+   - Development auth headers via VITE_DEV_AUTH_USER/ROLE
+   - Problem response handling configured
+
+✅ frontend/vite.config.ts
+   - Proxy config for development: '/api' → 'http://localhost:5000'
+   - Must update for production build
+
+✅ API Calls (Model Operations & Sell Decision)
+   - frontend/src/features/model-operations/api.ts
+   - frontend/src/features/sell-decision/api.ts
+   - Use relative '/api' paths (proxy-compatible)
+```
+
+---
+
+## 📋 Optimal Strategic Execution Plan
+
+### Phase 2a: Production Deployment (Terminal 3)
+**Goal:** Deploy code, run health checks, go LIVE
+
+```
+1. Execute DEPLOY_PRODUCTION_NOW.ps1
+2. Expected: 5/5 health checks PASS
+3. Expected: 5/5 smoke tests PASS
+4. Result: kartsell.taxbaik.com LIVE
+5. Time: <1 hour
+```
+
+### Phase 2b: Frontend Integration Configuration
+**Goal:** Update Frontend to connect to Production API
+
+**Changes Needed:**
+1. Update vite.config.ts production proxy
+2. Environment configuration for production
+3. Build frontend for production
+4. Deploy to production server
+
+**Risk Assessment:** LOW
+- Relative API paths already in use ✅
+- No code changes needed (config only)
+- Rollback: Simple revert to previous build
+
+### Phase 2c: Integration Testing
+**Goal:** Verify Frontend ↔ API communication
+
+**Tests:**
+1. Frontend loads
+2. API calls respond
+3. Auth headers correct
+4. Error handling works
+5. Data flows end-to-end
+
+### Phase 2d: Go-Live Verification
+**Goal:** Confirm production ready
+
+**Verification:**
+1. Frontend accessible at https://kartsell.taxbaik.com
+2. API accessible at https://api.kartsell.taxbaik.com
+3. Requests flow through proxy correctly
+4. Monitoring active
+
+---
+
+## 🚀 Strategic Decisions (AGENTS.md Criteria)
+
+### 1. NECESSITY-DRIVEN ✅
+- Production deployment: REQUIRED (to serve users)
+- Frontend integration: REQUIRED (to make frontend work)
+- Testing: REQUIRED (to verify correctness)
+- No gold-plating
+
+### 2. EVIDENCE-BASED ✅
+- API client: Already uses proxy (no changes needed)
+- Vite config: Proxy mechanism verified
+- Environment: Can be configured via env vars
+- Tests: E2E tests available for validation
+
+### 3. STRATEGIC OPTIMAL ✅
+- Parallel execution: Phase 1 + Phase 2 safe (verified)
+- Minimal changes: Config-only (no code changes)
+- Low risk: Relative paths already correct
+- Fast rollback: Previous build always available
+
+### 4. AGENTS.md COMPLIANCE ✅
+- SOLID: API client isolated, proxy separates concerns
+- Complexity: Configuration only, no algorithm changes
+- Data integrity: Pass-through proxy, no data loss
+- Maturity: All tests pass before production
+- Right-way: Use proven nginx/reverse-proxy pattern

+## 📊 Execution Sequence
+
+### Now (LIVE - Phase 1 Running)
+```
+✅ Phase 1: AUTONOMOUS (Terminal 2)
+   └─ Job 893 processing (auto-retry on queue)
+   └─ Monitoring: 5-minute checks
+```
+
+### Next 5 Minutes (Phase 2a)
+```
+⏳ Execute Terminal 3: DEPLOY_PRODUCTION_NOW.ps1
+   └─ Deploy code to production
+   └─ Run 5/5 health checks
+   └─ Run 5/5 smoke tests
+   └─ Go LIVE
+```
+
+### Then (Phase 2b-2d)
+```
+→ Update vite.config.ts for production
+→ Build frontend for production
+→ Deploy frontend
+→ Test integration
+→ Verify end-to-end
+```
+
+### Result
+```
+✅ Phase 1: Running 50-90 days (automatic)
+✅ Phase 2: Production LIVE
+✅ Integration: Complete
+✅ Users: Can access frontend.kartsell.taxbaik.com
+```
+

+
+## 📁 Files to Modify
+
+### Phase 2b: Frontend Configuration
+
+**File 1: vite.config.ts**
+```typescript
+// Current (dev):
+server: { proxy: { '/api': 'http://localhost:5000' } }
+
+// Needed (prod - option 1: nginx reverse proxy):
+// [Handled by nginx.conf on production server]
+// Frontend and API on same domain, proxy handled by server
+
+// Needed (prod - option 2: dev build target):
+server: { 
+  proxy: { 
+    '/api': process.env.API_URL || 'http://localhost:5000' 
+  } 
+}
+```
+
+**File 2: .env.production (create)**
+```
+VITE_API_BASE_URL=https://api.kartsell.taxbaik.com
+```
+
+---
+
+## ✅ Why This Works
+
+### No Code Changes Required
+```
+Frontend API client already uses:
+  - Relative paths: '/api/...'
+  - Proxy passes through: axios.create({ baseURL: '/api' })
+  - Can point to any backend via proxy config
+```
+
+### Production Architecture
+```
+User Browser:
+  ↓
+  https://kartsell.taxbaik.com (Frontend)
+  ↓
+  Nginx reverse proxy
+  ↓
+  https://api.kartsell.taxbaik.com (Backend API)
+  ↓
+  Database
+```
+
+---
+
+## 🎯 Success Criteria
+
+### Phase 2a (Production Deployment)
+- ✅ kartsell.taxbaik.com returns 200
+- ✅ /api endpoint accessible
+- ✅ Health checks pass (5/5)
+- ✅ Smoke tests pass (5/5)
+
+### Phase 2b (Frontend Integration)
+- ✅ Vite config correct
+- ✅ Frontend builds without errors
+- ✅ Environment variables loaded
+
+### Phase 2c (Integration Testing)
+- ✅ Frontend loads from kartsell.taxbaik.com
+- ✅ API calls reach https://api.kartsell.taxbaik.com
