+# Build Error Resolution & Build Performance Monitoring
+
+## 🎯 Overview
+
+This PR addresses critical build errors that were preventing successful Next.js builds and introduces build performance monitoring to help identify optimization opportunities. The changes ensure production-ready builds while providing visibility into build performance metrics.
+
+## 🔍 Context
+
+### Problem Statement
+1. **Build Errors**: Multiple API routes were causing "Dynamic server usage" build errors due to implicit dynamic behavior when using `getServerSession()`
+2. **Performance Visibility**: No visibility into build duration, making it difficult to identify performance bottlenecks
+3. **Developer Experience**: Build failures were blocking deployments without clear error messages
+
+### Impact
+- ❌ Build failures preventing deployments
+- ❌ Unclear build performance metrics
+- ❌ Developer time wasted on debugging build issues
+
+## ✨ Changes Made
+
+### 1. Build Error Resolution
+
+**Fixed "Dynamic server usage" errors** by explicitly marking API routes as dynamic:
+
+Added `export const dynamic = 'force-dynamic'` to 5 API routes that use `getServerSession()`:
+- `src/app/api/equipment/maintenance/route.ts`
+- `src/app/api/notifications/preferences/route.ts`
+- `src/app/api/search/route.ts`
+- `src/app/api/species/observations/route.ts`
+- `src/app/api/species/with-locations/route.ts`
+
+**Rationale**: These routes inherently require dynamic server-side rendering due to authentication checks. Explicitly marking them prevents Next.js from attempting static optimization and eliminates build warnings/errors.
+
+### 2. Build Performance Monitoring
+
+**Introduced build timing script** (`scripts/time-build.js`):
+- Measures total build duration
+- Displays build time in human-readable format (minutes and seconds)
+- Provides clear success/failure indicators
+- Integrated into `package.json` build script
+
+**Benefits**:
+- 📊 Track build performance over time
+- 🎯 Identify performance regressions
+- ⚡ Optimize build process based on metrics
+- 📈 Monitor CI/CD pipeline performance
+
+### 3. Code Quality Improvements
+
+- ✅ Resolved merge conflicts with latest `main` branch
+- ✅ Removed empty test files that were causing test suite failures
+- ✅ Ensured all linting and type checks pass
+- ✅ Maintained consistency with existing codebase patterns
+
+## 🔗 Related Work
+
+### Related PRs
+- **PR #76**: Implemented performance optimizations (caching, pagination) that complement this work
+- This PR ensures the build process works correctly with those optimizations
+
+### Milestone
+- **v1.3 - Quality & Polish**: This PR contributes to overall code quality and developer experience improvements
+
+### Related Issues
+- Resolves build errors that were blocking deployments
+- Addresses lack of build performance visibility
+
+## 🧪 Testing
+
+### Test Coverage
+- ✅ All existing unit tests pass
+- ✅ Integration tests pass
+- ✅ Linting and type checking pass
+- ✅ Build completes successfully
+
+### Manual Testing
+1. **Build Process**:
+   ```bash
+   npm run build
+   ```
+   - ✅ Build completes without errors
+   - ✅ Build time is displayed correctly
+   - ✅ Success/failure indicators work
+
+2. **API Routes**:
+   - ✅ All 5 modified routes build without warnings
+   - ✅ Routes function correctly in development and production
+   - ✅ Authentication checks work as expected
+
+## 📊 Metrics & Impact
+
+### Before
+- ❌ Build failures due to dynamic server usage warnings
+- ❌ No build performance visibility
+- ❌ Unclear error messages
+
+### After
+- ✅ Clean builds without errors or warnings
+- ✅ Build performance metrics available
+- ✅ Clear success/failure indicators
+- ✅ Improved developer experience
+
+## 🚀 Deployment Notes
+
+### Breaking Changes
+- **None**: All changes are backward compatible
+
+### Migration Steps
+- No migration required
+- Build script automatically uses new timing functionality
+
+### Rollback Plan
+- Revert `package.json` build script to `next build` if needed
+- Remove `export const dynamic = 'force-dynamic'` from routes (not recommended as it will reintroduce build errors)
+
+## 📝 Code Quality
+
+### Standards Met
+- ✅ Follows project coding standards
+- ✅ TypeScript types are correct
+- ✅ ESLint rules pass
+- ✅ No console.logs or debug code
+- ✅ Proper error handling
+- ✅ Code is self-documenting
+
+### Files Changed
+- **26 files** modified/added
+- **+1,082** additions
+- **-712** deletions
+
+### Key Files
+- `scripts/time-build.js` - New build timing script
+- `package.json` - Updated build script
+- 5 API route files - Added dynamic export
+- Multiple client page components - Server to client conversion

+
+## 📚 Additional Notes
+
+### Technical Details
+
+**Why `force-dynamic`?**
+Next.js attempts to statically optimize API routes by default. However, routes using `getServerSession()` require dynamic server-side execution because:
+1. Authentication state is determined at request time
+2. Session data is user-specific and cannot be pre-rendered
+3. Database queries depend on authenticated user context
+
+Explicitly marking these routes as `force-dynamic` tells Next.js to skip static optimization, eliminating build warnings and ensuring correct runtime behavior.
+
+**Build Timing Script**
+The script uses Node.js `child_process.spawn()` to execute the Next.js build and measure duration. It provides:
+- Real-time build output (stdio: 'inherit')
+- Accurate timing (millisecond precision)
+- Human-readable output format
+- Proper exit code propagation
+
+## 🔄 Future Improvements
+
+Potential enhancements for future PRs:
+- [ ] Add build performance tracking/trending
+- [ ] Integrate build metrics into CI/CD dashboards
+- [ ] Add build cache optimization
+- [ ] Consider incremental builds for faster development
