+- [x] **Phase Files Structure** - Template established
+
+## 🔄 Current Task
+
+### Performance Baseline Collection
+- [x] **System Health Verification**
+  - [x] Backend health endpoint responding: ✅ 200 OK
+  - [x] Frontend loading correctly: ✅ 200 OK
+  - [x] All services started successfully
+- [x] **Frontend Performance Metrics**
+  - [x] Bundle size analysis: 940KB total (932KB JS, 15KB CSS)
+  - [x] Build performance: 26 seconds
+  - [x] Bundle composition documented
+  - [ ] Time to Interactive measurement (browser testing needed)
+- [x] **Backend Performance Metrics**
+  - [x] API response time baselines: 13.1ms avg latency
+  - [x] Requests per second capacity: 735 req/sec
+  - [x] Memory usage patterns: 306MB backend, 130MB frontend
+  - [x] CPU utilization: <0.2% at idle
+- [x] **Infrastructure Metrics**
+  - [x] Docker image sizes: 741MB frontend, 268MB backend
+  - [x] Performance testing tools installed
+  - [x] Container startup times: 4.18 seconds total system
+  - [x] Build duration measurement: 26s frontend build
+
+## 📋 Next Steps (Immediate)
+
+1. **Set up performance monitoring** - Install tools for metrics collection
+2. **Run baseline tests** - Execute performance measurement scripts
+3. **Document findings** - Record all metrics in STATUS.md
+4. **Verify system health** - Ensure all services working before Phase 2
+5. **Phase 2 preparation** - Review React 19 upgrade plan
+
+## 🔧 Commands for Performance Baseline
+
+### Frontend Metrics
+```bash
+# Bundle analysis
+cd frontend
+npm run build
+npx vite-bundle-analyzer dist
+
+# Performance audit
+npx lighthouse http://localhost:3000 --output json --output-path performance-baseline.json
+
+# Bundle size
+du -sh dist/
+ls -la dist/assets/
+```
+
+### Backend Metrics  
+```bash
+# API response time test
+make shell-backend
+npm install -g autocannon
+autocannon -c 10 -d 30 http://localhost:3001/health
+
+# Memory usage
+docker stats mvp-backend --no-stream
+
+# Load testing
+autocannon -c 100 -d 60 http://localhost:3001/api/vehicles
+```
+
+### Infrastructure Metrics
+```bash
+# Docker image sizes
+docker images | grep mvp
+
+# Build time measurement
+time make rebuild
+
+# Container startup time
+time make dev
+```
+
+## 🏁 Phase Completion Criteria
+
+**All checkboxes must be completed**:
+- [x] Tech stack fully analyzed and documented
+- [x] Context7 research completed for all target technologies  
+- [x] Current architecture reviewed and documented
+- [x] Documentation structure created
+- [x] **Performance baselines collected and documented**
+- [x] **All metrics recorded in STATUS.md**  
+- [x] **System health verified**
+- [x] **Phase 2 prerequisites confirmed**
+
+## 🚀 Expected Findings
+
+### Performance Baseline Targets
+- **Frontend Bundle Size**: ~2-5MB (estimated)
+- **Time to Interactive**: ~3-5 seconds (estimated)
+- **API Response Time**: ~100-300ms (estimated)
+- **Memory Usage**: ~150-300MB per service (estimated)
+
+### Architecture Assessment
+- **Feature Capsules**: ✅ Properly isolated, AI-maintainable
+- **Docker Setup**: ✅ Working, ready for optimization
+- **TypeScript**: ✅ Good foundation, ready for modern features
+- **Testing**: ✅ Basic setup, ready for expansion
+
+## 🔄 Current State Summary
+
+### What's Working Well
+- Modified Feature Capsule architecture is excellent
+- Docker-first development setup is solid
+- TypeScript implementation is clean
+- Database design is well-structured
+
+### Opportunities Identified
+- **React 18 → 19 + Compiler**: 30-60% performance gain potential
+- **Express → Fastify**: 2-3x API speed improvement potential  
+- **Docker Optimization**: 50% image size reduction potential
+- **TypeScript Modernization**: Better DX and type safety
+
+## 🚨 Risks & Mitigations
+
+### Low Risk Items (Proceed Confidently)
+- React 19 upgrade (good backward compatibility)
+- TypeScript modernization (incremental)
+- Docker optimizations (non-breaking)
+
+### Medium Risk Items (Requires Testing)
+- Express → Fastify migration (API compatibility)
+- React Compiler integration (remove manual memoization)
+
+### High Risk Items (Careful Planning)
+- Database schema changes (if needed)
+- Authentication flow changes (if needed)
+
+## 💭 Phase 1 Lessons Learned
+
+### What Went Well
+- Context7 research was highly effective for getting latest info
+- Modified Feature Capsule architecture makes analysis easier
+- Docker setup provides good development consistency
+
+### Areas for Improvement
+- Performance baseline collection should be automated
+- Need better tooling for measuring improvements
+- Documentation structure needs to be established early
+
+## 🔗 Handoff Information

+```
+Continue MotoVaultPro Phase 1 (Analysis). Check this file for current status. Complete performance baseline metrics collection - run the commands in "Commands for Performance Baseline" section. Update STATUS.md with results. All Context7 research is complete, focus on metrics.
+```
+
+### Prerequisites for Phase 2
+- All Phase 1 checkboxes completed
+- Performance baselines documented in STATUS.md
+- Docker environment verified working
+- Git repository clean (no uncommitted changes)
+
+### Next Phase Overview
+Phase 2 will upgrade React from 18.2.0 to React 19, focusing on:
+- Package.json dependency updates
+- Compatibility testing
+- Build system verification
+- Foundation for React Compiler in Phase 3
