+
+### 2. Backend API Implementation
+
+#### API Client (`frontends/nextjs/src/lib/entities/api-client.ts`)
+**Changes**: Replaced all placeholder implementations with real fetch calls
+
+**Before** (placeholder):
+```typescript
+export function fetchEntityList(...) {
+  // TODO: Implement actual API call
+  return { data: [], status: 200 }
+}
+```
+
+**After** (real implementation):
+```typescript
+export async function fetchEntityList(...) {
+  const response = await fetch(url, { method: 'GET', ... })
+  const data = await response.json()
+  return { data, status: response.status }
+}
+```
+
+**Features Added**:
+- ListQueryParams interface for pagination/filtering/sorting
+- buildQueryString() utility
+- Proper error handling with status code mapping
+- Network error handling
+- Support for all HTTP methods (GET, POST, PUT, DELETE)

+
+## Architecture Notes
+
+### Existing Infrastructure (Leveraged)
+The following were already implemented and working:
+- ✅ API routes at `/api/v1/[...slug]/route.ts`
+- ✅ Authentication middleware with session management
+- ✅ Permission level checks (6-level system)
+- ✅ Tenant isolation validation
+- ✅ DBAL (Database Abstraction Layer)
+- ✅ Package system with JSON components
+
+### New Additions
+- ✅ Real API client implementation (no more placeholders)
+- ✅ Query parameter support (pagination, filtering, sorting)
+- ✅ Comprehensive test coverage
+- ✅ Detailed documentation
+
+---
+
+## Breaking Changes
+
+**None.** All changes are additive or replace placeholder implementations.
+
+- Existing tests: Still passing (same 4 pre-existing failures)
+- API routes: Already existed, no changes
+- Database schema: No changes
+- Configuration: No changes
+
+---
+
+## Performance Impact
+
+### API Client
+- **Before**: Synchronous placeholder (instant but fake)
+- **After**: Asynchronous fetch calls (real network requests)
+- **Impact**: Minimal - proper async handling already in place
+
+### Test Suite
+- **Before**: 220 tests in ~20 seconds
+- **After**: 249 tests in ~22 seconds (+2 seconds for 29 new tests)
+- **Impact**: Negligible - well within acceptable range
+
+---
+
+## Next Steps
+
+Based on ROADMAP.md Phase 2 plan:
+
+### Immediate (Week 2-3, Q1 2026)
+- [ ] Request/response validation with Zod
+- [ ] Rate limiting implementation
+- [ ] OpenAPI/Swagger specification
+
+### Short-term (Week 4-6, Q1 2026)
+- [ ] Enhanced CRUD UX (RenderComponent forms)
+- [ ] Client-side validation
+- [ ] Advanced list features (search, bulk operations)
+
+### Medium-term (Q2 2026)
+- [ ] God Panel UI
+- [ ] Package management UI
+- [ ] Schema editor
+
+---
+
+## How to Use
+
+### Run Unit Tests
+```bash
+cd frontends/nextjs
+npm test
+```
+
+### Run E2E Tests
+```bash
+# From root
+npm run test:e2e
+
+# Specific test file
+npx playwright test e2e/crud/complete-flow.spec.ts
+npx playwright test e2e/auth/complete-flow.spec.ts
+npx playwright test e2e/package-loading.spec.ts
+```
+
+### Use API Client
+```typescript
+import {
+  fetchEntityList,
+  fetchEntity,
+  createEntity,
+  updateEntity,
+  deleteEntity,
+} from '@/lib/entities/api-client'
+
+// List with pagination and filtering
+const { data, error } = await fetchEntityList('acme', 'forum', 'posts', {
+  page: 1,
+  limit: 20,
+  filter: { published: true },
+  sort: '-createdAt',
+})
+
+// Create entity
+const newPost = await createEntity('acme', 'forum', 'posts', {
+  title: 'New Post',
+  content: 'Content here',
+})
+
+// Update entity
+const updated = await updateEntity('acme', 'forum', 'posts', '123', {
+  published: true,
+})
+
+// Delete entity
+await deleteEntity('acme', 'forum', 'posts', '123')
+```
