## Build Metrics

**Final Build Output:**
```
✓ Compiled successfully in 6.4s
✓ Generating static pages using 3 workers (4/4) in 214.8ms

Route (app)
┌ ○ /              (Static homepage)
├ ○ /_not-found    (Static 404 page)
└ ƒ /api/users     (Dynamic API route with DBAL)

○  (Static)   prerendered as static content
ƒ  (Dynamic)  server-rendered on demand
```

**Statistics:**
- TypeScript compilation: ✅ SUCCESS (0 errors)
- Static pages generated: 2
- API routes: 1
- Build time: ~6.5 seconds
- Bundle optimization: Turbopack enabled

## Architecture Changes

### Database Layer
**Before:** Direct Spark KV storage  
**After:** Hybrid approach
- Client components: Direct Prisma access (backward compatible)
- Server components: DBAL with Prisma adapter (advanced features)

### Component Architecture
**Before:** Vite SPA with client-side rendering only  
**After:** Next.js App Router with:
- Server Components for static content
- Client Components for interactive features
- Proper boundaries with `'use client'` directives
- API Routes for server-side operations

### DBAL Integration
- **Server-only module:** `src/lib/database-dbal.server.ts`
- **Prisma adapter:** Fully configured and working
- **Type mapping:** DBAL User ↔ App User types
- **Example usage:** `/api/users` route

## Key Features Preserved

✅ All 5 security levels (public, user, admin, god, supergod)  
✅ Prisma database integration  
✅ Tailwind CSS styling  
✅ shadcn/ui components  
✅ Authentication system  
✅ Lua script execution  
✅ Component hierarchy system  
✅ Package management  
✅ Multi-tenant support  

## Files Modified

### Configuration (6 files)
- `next.config.ts` - Turbopack configuration
- `tsconfig.json` - Updated for Next.js
- `.gitignore` - Added Next.js build artifacts
- `package.json` - Updated dependencies
- `app/layout.tsx` - Root layout configuration
- `vite.config.ts` - Stubbed (no longer used)

### DBAL Layer (8 files)
- `dbal/ts/src/adapters/prisma-adapter.ts`
- `dbal/ts/src/blob/*.ts` (4 files)
- `dbal/ts/src/core/kv-store.ts`
- `src/lib/dbal-integration.ts`
- `src/lib/database-dbal.server.ts` (NEW)

### Components (6 files)

- `src/components/ui/sonner.tsx` - Added `'use client'`

### Utilities (5 files)
- `src/lib/database.ts` - Switched to Prisma implementation

- `src/lib/secure-db-layer.ts` - Removed Spark KV
- `src/lib/security-scanner.ts` - Fixed regex pattern

## Known Issues & TODOs

### Minor Items
1. Google Fonts temporarily disabled (network restrictions) - using link tags
2. `tw-animate-css` import commented out - pending Turbopack resolution
3. Audit log storage using console.log - TODO: database implementation
4. Modular package storage stubbed - TODO: database implementation

### Future Enhancements
1. Implement persistent KV storage (currently in-memory)
2. Re-enable Google Fonts with next/font optimization
3. Re-enable tw-animate-css with proper import
4. Create more API routes for DBAL operations
5. Add SSR/SSG optimization where beneficial
6. Implement image optimization with next/image
