USER ACTION REQUIRED

To Test Phase 1:
1. Get app passwords for 2 Gmail accounts
   → https://myaccount.google.com/apppasswords
   
2. Fill in backend/.env with credentials
   → See .env.example for instructions
   
3. Start Docker Desktop
   → Then run: docker-compose up -d
   
4. Install & run backend
   → cd backend
   → npm install
   → npm run dev
   
5. Test real-time sync (CRITICAL!)
   → Send email to configured account
   → Watch terminal for notification
   → Verify appears in API within 30 seconds

Expected Time: 10-15 minutes

═══════════════════════════════════════════════════════════════

SUCCESS CRITERIA

Phase 1 is complete when user confirms:
□ Backend starts without errors
□ Both accounts show "connected: true"
□ Emails from last 30 days synced
□ Real-time sync works (new email detected)
□ All API endpoints return data
□ Console shows detailed logs

═══════════════════════════════════════════════════════════════

NEXT PHASES (After User Confirms Phase 1)

Phase 2: Elasticsearch Integration (1-2 hours)
□ Index emails in Elasticsearch
□ Full-text search
□ Advanced filtering
□ Persistent storage

Phase 3: AI Categorization (2 hours)
□ Gemini API integration
□ 5 categories (Interested, Meeting Booked, etc.)
□ Auto-categorize on new emails
□ Store in Elasticsearch

Phase 4: Slack & Webhooks (1 hour)
□ Slack notifications for "Interested"
□ Webhook calls with retry logic
□ webhook.site integration

Phase 5: React Frontend (3-4 hours)
□ TypeScript React UI
□ Email list with pagination
□ Search interface
□ Filters (account/folder/category)
□ Real-time updates

Phase 6: AI Reply Suggestions - RAG (3-4 hours)
□ Vector database setup
□ Retrieval-Augmented Generation
□ Gemini-powered replies
□ Meeting link automation
□ Context-aware suggestions

Total Remaining: ~10-13 hours of implementation
