-GOODGO PLATFORM FRONTEND EXPLORATION - EXECUTIVE SUMMARY
-================================================================================
-
-Date: April 9, 2026
-Status: Complete ✅
-Scope: Very Thorough
-
-OVERVIEW
---------
-GoodGo is a Vietnamese real estate platform built with Next.js 14 (App Router).
-The frontend is well-structured with clear component organization, but has NO
-existing internationalization (i18n) setup. All UI text is hardcoded in Vietnamese.
-
-KEY FINDINGS
-============
-
-✅ STRENGTHS
-  • Next.js 14 with App Router (modern, well-organized routing)
-  • React 18 + TypeScript (type-safe development)
-  • Tailwind CSS with HSL-based theming (easy customization)
-  • Good component library (~35 components) using CVA patterns
-  • Existing accessibility basics (semantic HTML, ARIA labels, skip link)
-  • Zod validation schemas for data validation
-  • Zustand for state management
-  • React Query for data fetching
-  • Comprehensive middleware for auth routing
-  • Security headers configured (CSP, X-Frame-Options, etc.)
-
-❌ GAPS TO ADDRESS
-  • NO i18n setup (everything hardcoded Vietnamese)
-  • NO locale routing (/en/*, /vi/*)
-  • NO message files or translation system
-  • Accessibility issues: Focus management, color contrast, form error linking
-  • Some ARIA labels missing from icon-only buttons
-  • No focus trapping in dialogs/modals
-  • Loading states lack aria-busy
-

+# Admin Module - Untested Handlers/Source Files Analysis
+
+## Executive Summary
+
+This document provides a comprehensive analysis of untested source files in the admin module (`apps/api/src/modules/admin/`), with detailed code listings and testing patterns for reference.
+
+**Analysis Date:** 2026-04-11
+
+---
+
+## 1. UNTESTED HANDLER FILES
+
+### 1.1 reject-listing.handler.ts (Commands)
+
+**Path:** `apps/api/src/modules/admin/application/commands/reject-listing/reject-listing.handler.ts`
+
+**Status:** ❌ NO TEST FILE FOUND
+
+#### Source Code:
+```typescript
+import { Inject } from '@nestjs/common';
+import { CommandHandler, type EventBus, type ICommandHandler } from '@nestjs/cqrs';
+import { LISTING_REPOSITORY, type IListingRepository } from '@modules/listings';
+import { NotFoundException, ValidationException } from '@modules/shared';
+import { ListingRejectedEvent } from '../../../domain/events/listing-rejected.event';
+import { RejectListingCommand } from './reject-listing.command';
+
+export interface RejectListingResult {
+  listingId: string;
+  status: string;
+  message: string;
+}
+
+@CommandHandler(RejectListingCommand)
+export class RejectListingHandler implements ICommandHandler<RejectListingCommand> {
+  constructor(
+    @Inject(LISTING_REPOSITORY) private readonly listingRepo: IListingRepository,
+    private readonly eventBus: EventBus,
+  ) {}
+
+  async execute(command: RejectListingCommand): Promise<RejectListingResult> {
+    const listing = await this.listingRepo.findById(command.listingId);
+    if (!listing) {
+      throw new NotFoundException('Listing không tồn tại');
+    }
+
+    if (listing.status !== 'PENDING_REVIEW') {
+      throw new ValidationException(
+        `Listing đang ở trạng thái ${listing.status}, chỉ có thể từ chối listing đang chờ duyệt`,
+        { currentStatus: listing.status },
+      );
+    }
+
+    listing.reject(command.reason);
+    await this.listingRepo.update(listing);
+
+    this.eventBus.publish(
+      new ListingRejectedEvent(listing.id, command.adminId, command.reason),
+    );
+
+    return {
+      listingId: listing.id,
+      status: 'REJECTED',
+      message: 'Listing đã bị từ chối',
+    };
+  }
+}
+```
+
+#### Associated Command Class:
+```typescript
+export class RejectListingCommand {
+  constructor(
+    public readonly listingId: string,
+    public readonly adminId: string,
+    public readonly reason: string,
+  ) {}
+}
+```
+
+#### Key Testing Points:
+- ✅ Successfully rejects a PENDING_REVIEW listing
+- ✅ Throws NotFoundException when listing doesn't exist
+- ✅ Throws ValidationException when listing is not in PENDING_REVIEW status
+- ✅ Calls listingRepo.update() exactly once
+- ✅ Publishes ListingRejectedEvent with correct data
+- ✅ Returns correct RejectListingResult with status 'REJECTED'
+

+
+### 1.2 get-revenue-stats.handler.ts (Queries)
+
+**Path:** `apps/api/src/modules/admin/application/queries/get-revenue-stats/get-revenue-stats.handler.ts`
+
+**Status:** ❌ NO TEST FILE FOUND
+
+#### Source Code:
+```typescript
+import { Inject } from '@nestjs/common';
+import { QueryHandler, type IQueryHandler } from '@nestjs/cqrs';
+import { ADMIN_QUERY_REPOSITORY, type IAdminQueryRepository, type RevenueStatsItem } from '../../../domain/repositories/admin-query.repository';
+import { GetRevenueStatsQuery } from './get-revenue-stats.query';
+
+@QueryHandler(GetRevenueStatsQuery)
+export class GetRevenueStatsHandler implements IQueryHandler<GetRevenueStatsQuery> {
+  constructor(
+    @Inject(ADMIN_QUERY_REPOSITORY) private readonly adminQueryRepo: IAdminQueryRepository,
+  ) {}
+
+  async execute(query: GetRevenueStatsQuery): Promise<RevenueStatsItem[]> {
+    return this.adminQueryRepo.getRevenueStats(query.startDate, query.endDate, query.groupBy);
+  }
+}
+```
+
+#### Associated Query Class:
+```typescript
+export class GetRevenueStatsQuery {
+  constructor(
+    public readonly startDate: Date,
+    public readonly endDate: Date,
+    public readonly groupBy: 'day' | 'month' = 'month',
+  ) {}
+}
+```
+
+#### RevenueStatsItem Interface:
+```typescript
+export interface RevenueStatsItem {
+  period: string;
+  totalRevenue: bigint;
+  subscriptionRevenue: bigint;
+  listingFeeRevenue: bigint;
+  featuredListingRevenue: bigint;
+  transactionCount: number;
+}
+```
+
+#### Key Testing Points:
+- ✅ Returns RevenueStatsItem[] from repository
+- ✅ Passes correct startDate, endDate, and groupBy parameters
+- ✅ Calls adminQueryRepo.getRevenueStats() exactly once
+- ✅ Supports both 'day' and 'month' groupBy values
+- ✅ Default groupBy is 'month'
+- ✅ Handles empty results (empty array)
+

+
+### 1.3 user-deactivated.listener.ts (Listeners)
+
+**Path:** `apps/api/src/modules/admin/application/listeners/user-deactivated.listener.ts`
+
+**Status:** ❌ NO TEST FILE FOUND
+
+#### Source Code:
+```typescript
+import { Injectable } from '@nestjs/common';
+import { OnEvent } from '@nestjs/event-emitter';
+import { type UserDeactivatedEvent } from '@modules/auth';
+import { type LoggerService, type PrismaService } from '@modules/shared';
+
+@Injectable()
+export class UserDeactivatedListener {
+  constructor(
+    private readonly prisma: PrismaService,
+    private readonly logger: LoggerService,
+  ) {}
+
+  @OnEvent('user.deactivated', { async: true })
+  async handle(event: UserDeactivatedEvent): Promise<void> {
+    this.logger.log(`Handling user.deactivated for user ${event.aggregateId}`, 'UserDeactivatedListener');
+
+    const deactivated = await this.prisma.listing.updateMany({
+      where: {
+        sellerId: event.aggregateId,
+        status: { in: ['ACTIVE', 'PENDING_REVIEW'] },
+      },
+      data: { status: 'EXPIRED' },
+    });
+
+    this.logger.log(
+      `Expired ${deactivated.count} listings for deactivated user ${event.aggregateId}`,
+      'UserDeactivatedListener',
+    );
+  }
+}
+```
+
+#### Key Testing Points:
+- ✅ Handles 'user.deactivated' event (async: true)
+- ✅ Updates listings with status ACTIVE or PENDING_REVIEW to EXPIRED
+- ✅ Only updates listings for the deactivated seller
+- ✅ Logs initial event handling
+- ✅ Logs number of expired listings after operation
+- ✅ Returns void (Promise<void>)
+- ✅ Handles case with 0 listings updated
+- ✅ Handles case with multiple listings updated

+## 2. EXISTING TEST FILES STRUCTURE & PATTERNS
+
+### 2.1 Test File for Reference: approve-listing.handler.spec.ts
+
+**Path:** `apps/api/src/modules/admin/application/__tests__/approve-listing.handler.spec.ts`
+
+#### Complete Source Code:
+```typescript
+import { ListingEntity } from '@modules/listings/domain/entities/listing.entity';
+import { type IListingRepository } from '@modules/listings/domain/repositories/listing.repository';
+import { Price } from '@modules/listings/domain/value-objects/price.vo';
+import { ApproveListingCommand } from '../commands/approve-listing/approve-listing.command';
+import { ApproveListingHandler } from '../commands/approve-listing/approve-listing.handler';
+
+function createPendingListing(id = 'listing-1'): ListingEntity {
+  const price = Price.create(1_000_000_000n).unwrap();
+  const listing = ListingEntity.createNew(
+    id, 'prop-1', 'seller-1', 'SALE', price, 100, 'agent-1',
+  );
+  listing.submitForReview();
+  listing.clearDomainEvents();
+  return listing;
+}
+
+describe('ApproveListingHandler', () => {
+  let handler: ApproveListingHandler;
+  let mockListingRepo: { [K in keyof IListingRepository]: ReturnType<typeof vi.fn> };
+  let mockEventBus: { publish: ReturnType<typeof vi.fn> };
+
+  beforeEach(() => {
+    mockListingRepo = {
+      findById: vi.fn(),
+      findByIdWithProperty: vi.fn(),
+      save: vi.fn(),
+      update: vi.fn(),
+      search: vi.fn(),
+      findByStatus: vi.fn(),
+      findBySellerId: vi.fn(),
+    };
+
+    mockEventBus = { publish: vi.fn() };
+
+    handler = new ApproveListingHandler(
+      mockListingRepo as any,
+      mockEventBus as any,
+    );
+  });
+
+  it('approves a pending listing successfully', async () => {
+    const listing = createPendingListing();
+    mockListingRepo.findById.mockResolvedValue(listing);
+    mockListingRepo.update.mockResolvedValue(undefined);
+
+    const command = new ApproveListingCommand('listing-1', 'admin-1', 'Looks good');
+    const result = await handler.execute(command);
+
+    expect(result.status).toBe('ACTIVE');
+    expect(result.listingId).toBe('listing-1');
+    expect(mockListingRepo.update).toHaveBeenCalledTimes(1);
+    expect(mockEventBus.publish).toHaveBeenCalled();
+  });
+
+  it('throws NotFoundException when listing does not exist', async () => {
+    mockListingRepo.findById.mockResolvedValue(null);
+
+    const command = new ApproveListingCommand('nonexistent', 'admin-1');
+
+    await expect(handler.execute(command)).rejects.toThrow('Listing không tồn tại');
+  });
+
+  it('throws ValidationException when listing is not pending review', async () => {
+    const price = Price.create(500_000_000n).unwrap();
+    const listing = ListingEntity.createNew(

+    );
+    listing.clearDomainEvents();
+    mockListingRepo.findById.mockResolvedValue(listing);
+
+    const command = new ApproveListingCommand('listing-1', 'admin-1');
+
+    await expect(handler.execute(command)).rejects.toThrow(/trạng thái/);
+  });
+});
+```
+
+#### Key Patterns Used:
+1. **Factory Function:** `createPendingListing()` creates test entities
+2. **Mock Setup:** Typed mocks using `ReturnType<typeof vi.fn>`
+3. **Initialization:** beforeEach() sets up fresh mocks for each test
+4. **Entity Testing:** Uses actual domain entities with state transitions
+5. **Domain Events:** Clears domain events after setup with `.clearDomainEvents()`
+6. **Test Structure:**
+   - Happy path (success case)
+   - Error cases (NotFoundException, ValidationException)
+   - Side effect verification (repository calls, events published)

+### 2.2 Listener Test Pattern: user-banned.listener.spec.ts
+
+**Path:** `apps/api/src/modules/admin/application/__tests__/user-banned.listener.spec.ts`
+
+#### Complete Source Code:
+```typescript
+import { UserBannedListener } from '../listeners/user-banned.listener';
+
+describe('UserBannedListener', () => {
+  let listener: UserBannedListener;
+  let mockCommandBus: { execute: ReturnType<typeof vi.fn> };
+  let mockPrisma: {
+    listing: { updateMany: ReturnType<typeof vi.fn> };
+    user: { findUnique: ReturnType<typeof vi.fn> };
+  };
+  let mockLogger: { log: ReturnType<typeof vi.fn>; warn: ReturnType<typeof vi.fn> };
+
+  beforeEach(() => {

+  });
+
+  it('deactivates all user listings when banned', async () => {

+
+    await listener.handle({
+      aggregateId: 'user-1',
+      adminId: 'admin-1',
+      reason: 'Vi phạm chính sách',
+      eventName: 'user.banned',
+      occurredAt: new Date(),
+    });
+
+    expect(mockPrisma.listing.updateMany).toHaveBeenCalledWith({
+      where: {
+        sellerId: 'user-1',
+        status: { in: ['ACTIVE', 'PENDING_REVIEW', 'DRAFT'] },
+      },
+      data: { status: 'EXPIRED' },
+    });
+  });
+
+  it('notifies banned user via email', async () => {
+    mockPrisma.user.findUnique.mockResolvedValue({ id: 'user-1', email: 'user@example.com' });
+
+    await listener.handle({
+      aggregateId: 'user-1',
+      adminId: 'admin-1',
+      reason: 'Spam',
+      eventName: 'user.banned',
+      occurredAt: new Date(),
+    });
+
+    expect(mockCommandBus.execute).toHaveBeenCalledWith(
+      expect.objectContaining({
+        userId: 'user-1',
+        channel: 'EMAIL',
+        templateKey: 'user.banned',
+        templateData: { reason: 'Spam' },
+      }),
+    );
+  });
+
+  it('skips email notification when user has no email', async () => {
+    mockPrisma.user.findUnique.mockResolvedValue({ id: 'user-1', email: null });
+
+    await listener.handle({
+      aggregateId: 'user-1',
+      adminId: 'admin-1',
+      reason: 'Vi phạm',
+      eventName: 'user.banned',
+      occurredAt: new Date(),
+    });
+
+    expect(mockPrisma.listing.updateMany).toHaveBeenCalled();
+    expect(mockCommandBus.execute).not.toHaveBeenCalled();
+  });
+});
+```
+
+#### Listener Test Patterns:
+1. **Event Object Construction:** Manually create event with all properties
+2. **Multiple Dependencies:** Mock CommandBus, Prisma, Logger
+3. **Side Effects Testing:** Verify database calls and command execution
+4. **Conditional Logic:** Test both happy path and edge cases (no email)
+5. **Chained Operations:** Test interactions between multiple services

+### 2.3 Query Handler Pattern: get-dashboard-stats.handler.spec.ts
+
+**Path:** `apps/api/src/modules/admin/application/__tests__/get-dashboard-stats.handler.spec.ts`
+
+#### Complete Source Code:
+```typescript
+import { type IAdminQueryRepository } from '../../domain/repositories/admin-query.repository';
+import { GetDashboardStatsHandler } from '../queries/get-dashboard-stats/get-dashboard-stats.handler';
+import { GetDashboardStatsQuery } from '../queries/get-dashboard-stats/get-dashboard-stats.query';
+
+describe('GetDashboardStatsHandler', () => {
+  let handler: GetDashboardStatsHandler;
+  let mockAdminQueryRepo: { [K in keyof IAdminQueryRepository]: ReturnType<typeof vi.fn> };
+
+  beforeEach(() => {
+    mockAdminQueryRepo = {
+      getModerationQueue: vi.fn(),
+      getDashboardStats: vi.fn(),
+      getRevenueStats: vi.fn(),
+      getUsers: vi.fn(),
+    };
+
+    handler = new GetDashboardStatsHandler(mockAdminQueryRepo as any);
+  });
+
+  it('returns dashboard stats', async () => {
+    const stats = {
+      totalUsers: 150,
+      totalListings: 500,
+      activeListings: 200,
+      pendingModerationCount: 15,
+      totalAgents: 30,
+      verifiedAgents: 20,
+      totalTransactions: 50,
+      newUsersLast30Days: 25,
+      newListingsLast30Days: 40,
+    };
+
+    mockAdminQueryRepo.getDashboardStats.mockResolvedValue(stats);
+
+    const result = await handler.execute(new GetDashboardStatsQuery());
+
+    expect(result).toEqual(stats);
+    expect(mockAdminQueryRepo.getDashboardStats).toHaveBeenCalledTimes(1);
+  });
+});
+```
+
+#### Query Handler Test Patterns:
+1. **Simple Delegation:** Query handlers typically just delegate to repository
+2. **Minimal Setup:** Mock only the repository
+3. **Result Verification:** Check the returned data matches expectations
+4. **Call Count:** Verify the repository method was called exactly once

+## 4. INFRASTRUCTURE & REPOSITORY FILES (No tests required but provided for context)
+
+### 4.1 prisma-admin-query.repository.ts
+
+**Path:** `apps/api/src/modules/admin/infrastructure/repositories/prisma-admin-query.repository.ts`
+
+**Status:** ℹ️ Infrastructure layer - Integration tests may be appropriate instead
+
+**Note:** This is an implementation detail that delegates to more granular query functions. Consider integration tests instead of unit tests.
+
+---
+
+## 5. PRESENTATION LAYER FILES (No tests typically required)
+
+### 5.1 admin.controller.ts
+
+**Path:** `apps/api/src/modules/admin/presentation/controllers/admin.controller.ts`
+
+**Status:** ℹ️ Controllers typically use E2E tests, not unit tests
+
+**Note:** Controllers are tested via E2E/integration tests, not unit tests in this architecture.
+
+---
+
+## 6. TEST WRITING RECOMMENDATIONS
+
+### For reject-listing.handler.spec.ts
+
+Follow the pattern from `approve-listing.handler.spec.ts`:
+
+1. Create helper function to build listing entities
+2. Mock `IListingRepository` and `EventBus`
+3. Test 3 scenarios:
+   - Successfully rejects pending listing → publishes event
+   - Throws when listing doesn't exist
+   - Throws when listing not in PENDING_REVIEW status
+
+### For get-revenue-stats.handler.spec.ts
+
+Follow the pattern from `get-dashboard-stats.handler.spec.ts`:
+
+1. Mock `IAdminQueryRepository`
+2. Test single scenario:
+   - Returns results from repository.getRevenueStats() call
+3. Verify correct parameters passed:
+   - startDate, endDate, groupBy
+
+### For user-deactivated.listener.spec.ts
+
+Follow the pattern from `user-banned.listener.spec.ts`:
+
+1. Mock `PrismaService` and `LoggerService`
+2. Test scenarios:
+   - Successfully expires listings for deactivated user
+   - Updates both ACTIVE and PENDING_REVIEW listings
+   - Logs correct messages
+   - Handles case with 0 listings updated
+   - Handles case with multiple listings updated

+
+## 5️⃣ STYLING REFERENCE
+
+All components use:
+- **Tailwind CSS** classes directly (no CSS modules)
+- **Responsive breakpoints**: `md:`, `lg:`
+- **Dark mode**: Uses CSS variables in `globals.css`
+- **Component pattern**: Card → CardContent
+
+### Common spacing patterns:
+```typescript
+// Sections
+<section className="py-16 md:py-24">
+  <div className="mx-auto max-w-7xl px-4">
+    {/* content */}
+  </div>
+</section>
+
+// Cards
+<Card>
+  <CardContent className="p-4 md:p-6">
+    {/* content */}
+  </CardContent>
+</Card>
+
+// Grid
+<div className="grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4">
+  {/* items */}
+</div>
+```
+

+
+### Routing Patterns
+
+**Public Routes (under `(public)`):**
+- `/` → Home/landing page
+- `/listings/[id]` → Listing detail (EXISTING PATTERN)
+- `/search` → Search results page
+- `/compare` → Property comparison page
+- `/pricing` → Pricing page
+
+**Key Insight:** The `(public)` route group is for unauthenticated users. **Agent profiles should follow the same pattern: `/agents/[id]`** under the `(public)` group.
+

+
+## 2. EXISTING AGENT-RELATED CODE
+
+### Agent Profile Type (Frontend)
+**File:** `apps/web/lib/profile-api.ts`
+
+```typescript
+export interface AgentProfile {
+  id: string;
+  email: string | null;
+  phone: string;
+  fullName: string;

+  licenseNumber: string | null;
+  agency: string | null;
+  qualityScore: number | null;
+  serviceAreas: string[];
+  isVerified: boolean;
+}
+```
+
+### Existing Agent API Endpoints (Backend)
+**File:** `apps/api/src/modules/agents/presentation/controllers/agents.controller.ts`
+
+```typescript
+// Endpoints:
+GET    /agents/me/dashboard          # Agent dashboard (authenticated)
+POST   /agents/:agentId/recalculate-score  # Recalculate quality score (admin)

+  isVerified: boolean;
+  totalLeads: number;
+  leadsByStatus: Record<string, number>;
+  conversionRate: number;
+  totalInquiries: number;
+  unreadInquiries: number;
+  totalListings: number;
+  activeListings: number;
+  avgReviewRating: number;
+  totalReviews: number;
+}
+```
+
+### Prisma Schema — Agent Model
+**File:** `prisma/schema.prisma`
+
+```prisma
+model Agent {
+  id              String   @id @default(cuid())
+  userId          String   @unique
+  user            User     @relation(fields: [userId], references: [id])
+  licenseNumber   String?
+  agency          String?
+  qualityScore    Float    @default(0)
+  totalDeals      Int      @default(0)
+  responseTimeAvg Int?
+  bio             String?
+  serviceAreas    Json     // JSON array: ["quan-1", "quan-7", "thu-duc"]
+  isVerified      Boolean  @default(false)
+  createdAt       DateTime @default(now())
+  updatedAt       DateTime @updatedAt
+
+  listings Listing[]
+  leads    Lead[]
+
+  @@index([qualityScore])
+  @@index([isVerified])
+}
+```
+
+**Related models:**
+- `User` — Agent's user account (fullName, avatarUrl, phone, email, role, kycStatus)
+- `Listing` — Properties agent represents (has `agentId` foreign key)
+- `Lead` — Leads tracked by agent
+
+---
+
+## 3. AGENT API ENDPOINTS NEEDED FOR PUBLIC PROFILE
+
+Based on the existing architecture, we need to create a **public endpoint** to fetch agent profile data:
+
+### Proposed Endpoint
+
+```http
+GET /agents/:agentId/profile
+```
+
+**Response Structure (Public Profile DTO):**
+```typescript
+interface AgentPublicProfile {
+  id: string;
+  fullName: string;
+  avatarUrl: string | null;
+  
+  // Agent-specific fields
+  licenseNumber: string | null;
+  agency: string | null;
+  qualityScore: number;
+  bio: string | null;
+  serviceAreas: string[];
+  isVerified: boolean;
+  
+  // Stats
+  totalListings: number;
+  activeListings: number;
+  avgReviewRating: number;
+  totalReviews: number;
+  
+  // Contact (optional, may require user preferences)
+  phone?: string;
+  
+  // Timestamps
+  createdAt: string;
+  updatedAt: string;
+}
+```
+
+**Related Endpoints Needed:**
+```http
+GET /listings?agentId=:agentId&status=ACTIVE     # Agent's active listings
+GET /reviews/stats?targetType=AGENT&targetId=:agentId  # Agent reviews stats
+GET /reviews?targetType=AGENT&targetId=:agentId&limit=10  # Recent agent reviews
+```
+
+These endpoints already exist and are public (no authentication required).
+

+
+## 4. SHARED UI COMPONENTS & DESIGN PATTERNS
+
+### Tailwind/Design System
+**File:** `apps/web/tailwind.config.ts`
+
+```typescript
+// CSS Variables used (dark mode support)
+colors: {
+  primary, primary-foreground
+  secondary, secondary-foreground
+  destructive, destructive-foreground
+  muted, muted-foreground
+  accent, accent-foreground
+  card, card-foreground
+}
+
+// Radius variable: var(--radius)
+borderRadius: {
+  lg: 'var(--radius)',
+  md: 'calc(var(--radius) - 2px)',
+  sm: 'calc(var(--radius) - 4px)',
+}
+```
+
+### Available UI Components
+**File:** `apps/web/components/ui/`
+
+- `button.tsx` — Styled button with variants
+- `card.tsx` — Card (CardContent, etc.)
+- `badge.tsx` — Badge with variants
+- `input.tsx`, `label.tsx` — Form controls
+- `dialog.tsx` — Modal dialog
+- `tabs.tsx` — Tab navigation
+- `table.tsx` — Data table
+
+### Key Component Patterns
+
+#### Badge Component
+```typescript
+<Badge variant="default">Đã xác minh</Badge>
+<Badge variant="secondary">Info badge</Badge>
+<Badge variant="outline">Outline badge</Badge>
+<Badge variant="destructive">Danger</Badge>
+```
+
+#### Card Pattern
+```typescript
+<Card>
+  <CardContent className="p-4">
+    {/* Content */}
+  </CardContent>
+</Card>
+```
+
+#### Property Card (Listing Display) - REUSE THIS
+**File:** `apps/web/components/search/property-card.tsx`
+
+Shows a property with:
+- Image gallery
+- Price (formatted)
+- Title & address
+- Type, area, bedrooms badges
+- Transaction type badge
+
+**Reusable for:** Agent's listings display
+
+---
+
+## 5. STYLING & DESIGN PATTERNS
+
+### Global CSS
+**File:** `apps/web/app/globals.css`
+
+Uses CSS variables for theming:
+```css
+--primary: hsl(var(--primary-h), var(--primary-s), var(--primary-l))
+--background: hsl(...)
+--card: hsl(...)
+/* Dark mode support via [data-theme="dark"] */
+```
+
+### Typography
+- Font: Inter (configured in tailwind.config.ts via CSS variable `--font-inter`)
+- Heading levels: h1, h2, h3, h4
+- Use classes: `text-lg font-bold`, `text-sm text-muted-foreground`
+
+### Spacing
+- Tailwind standard: `p-4`, `mt-8`, `gap-3`, etc.
+- Card padding: `p-4`
+- Section padding: `py-16`, `py-24` for hero sections
+
+### Example Layout Pattern
+```typescript
+<section className="py-16 md:py-24">
+  <div className="mx-auto max-w-7xl px-4">
+    {/* Content */}
+  </div>
+</section>
+```
+
+---
+
+## 6. STATE MANAGEMENT & DATA FETCHING
+
+### API Client Pattern
+**File:** `apps/web/lib/api-client.ts`
+
+```typescript
+// Usage:
+const apiClient = {
+  get: <T>(endpoint: string, headers?: HeadersInit) => request<T>(endpoint, { method: 'GET', headers }),
+  post: <T>(endpoint: string, body?: unknown, headers?: HeadersInit) => request<T>(endpoint, { method: 'POST', body, headers }),
+  patch: <T>(endpoint: string, body?: unknown, headers?: HeadersInit) => request<T>(endpoint, { method: 'PATCH', body, headers }),
+  delete: <T>(endpoint: string, headers?: HeadersInit) => request<T>(endpoint, { method: 'DELETE', headers }),
+};
+
+// CSRF protection included automatically
+```
+
+### Server-Side Data Fetching Pattern
+**File:** `apps/web/lib/listings-server.ts`
+
+```typescript
+// Example: fetch on server at build time or request time
+export async function fetchListingById(id: string) {
+  try {
+    const res = await fetch(`${API_BASE_URL}/listings/${id}`, {
+      next: { revalidate: 3600 } // ISR: revalidate every 1 hour
+    });
+    if (!res.ok) return null;
+    return res.json();
+  } catch {
+    return null;
+  }
+}
+```
+
+### Client-Side Data Fetching Pattern
+```typescript
+// In React component (using 'use client')
+const [data, setData] = useState(null);
+
+React.useEffect(() => {
+  apiClient
+    .get('/endpoint')
+    .then((res) => setData(res))
+    .catch(() => setError(true))
+    .finally(() => setLoading(false));
+}, []);
+```
+
+### No Global State (Zustand)
+- **Currently no Zustand stores** for agent data in codebase
+- **Pattern:** Fetch data in page component → pass to child components
+- Dashboard uses local useState for profile fetch
+
+---
+
+## 7. SEO PATTERNS & STRUCTURED DATA
+
+### Metadata Generation Pattern
+**File:** `apps/web/app/[locale]/(public)/listings/[id]/page.tsx`
+
+```typescript
+export async function generateMetadata({ params }: PageProps): Promise<Metadata> {
+  const listing = await fetchListingById(params.id);
+  if (!listing) {
+    return { title: 'Không tìm thấy' };
+  }
+
+  return {
+    title: `${property.title} - ${formatPrice(listing.priceVND)} VND`,
+    description: '...',
+    alternates: {
+      canonical: `${siteUrl}/${params.locale}/listings/${params.id}`,
+      languages: { vi: '...', en: '...' }
+    },
+    openGraph: {
+      type: 'article',
+      locale: params.locale === 'vi' ? 'vi_VN' : 'en_US',
+      url: canonicalUrl,
+      title,
+      images: [{ url: firstImage.url, width: 1200, height: 630 }],
+    },
+    twitter: {
+      card: 'summary_large_image',
+      title,
+      images: [firstImage.url],
+    },
+  };
+}
+```
+
+### JSON-LD Structured Data
+**File:** `apps/web/components/seo/json-ld.tsx`
+
+```typescript
+// Example: RealEstateListing schema
+export function generateListingJsonLd(listing, siteUrl) {
+  return {
+    '@context': 'https://schema.org',
+    '@type': 'RealEstateListing',
+    name: property.title,
+    url: `${siteUrl}/listings/${listing.id}`,
+    offers: { '@type': 'Offer', price: priceNum, priceCurrency: 'VND' },
+    // ... more properties
+  };
+}
+
+// Usage in page:
+<JsonLd data={listingJsonLd} />
+<JsonLd data={breadcrumbJsonLd} />
+```
+
+### For Agent Profile (Schema.org)
+**Appropriate schema:** `LocalBusiness` or `ProfessionalService`
+
+```json
+{
+  "@context": "https://schema.org",
+  "@type": "LocalBusiness",
+  "name": "Agent Full Name",
+  "description": "Bio",
+  "url": "https://goodgo.vn/en/agents/[id]",
+  "image": "avatarUrl",
+  "address": {
+    "@type": "PostalAddress",
+    "addressLocality": "Ho Chi Minh"
+  },
+  "aggregateRating": {
+    "@type": "AggregateRating",
+    "ratingValue": avgReviewRating,
+    "reviewCount": totalReviews
+  }
+}
+```
+
+---
+
+## 8. EXISTING LISTING CARD COMPONENTS
+
+### Property Card Component
+**File:** `apps/web/components/search/property-card.tsx`
+
+```typescript
+interface PropertyCardProps {
+  listing: ListingDetail;
+  compact?: boolean;
+}
+
+// Displays:
+// - Image gallery (with count badge)
+// - Price (formatted)
+// - Title & address
+// - Badges: Transaction type, property type, area, bedrooms, bathrooms, direction
+// - Compare button
+```
+
+### Used in:
+- Home page featured listings
+- Search results
+- Comparison page
+
+**For Agent Profile:** Can reuse this component to display agent's listings!
+
+---
+
+## 9. REVIEW & RATING COMPONENTS
+
+### Review API Endpoints
+**File:** `apps/api/src/modules/reviews/presentation/controllers/reviews.controller.ts`
+
+```typescript
+// Endpoints:
+GET    /reviews                     # List reviews by target (pagination)
+GET    /reviews/stats               # Get aggregate rating stats
+GET    /reviews/me                  # Get authenticated user's reviews
+POST   /reviews                     # Create review (authenticated)
+DELETE /reviews/:id                 # Delete own review
+
+// Query params:
+GET /reviews?targetType=AGENT&targetId=:id&page=1&limit=20
+GET /reviews/stats?targetType=AGENT&targetId=:id
+```
+
+### Review DTO
+```typescript
+interface ReviewItemData {
+  id: string;
+  userId: string;
+  targetType: string;
+  targetId: string;
+  rating: number;        // 1-5
+  comment: string | null;
+  createdAt: string;
+  // User info:
+  user: {
+    id: string;
+    fullName: string;
+    avatarUrl: string | null;
+  };
+}
+
+interface ReviewStatsData {
+  targetType: string;
+  targetId: string;
+  totalReviews: number;
+  averageRating: number;
+  ratingDistribution: {
+    "1": number;
+    "2": number;
+    "3": number;
+    "4": number;
+    "5": number;
+  };
+}
+```
+
+### No Review Display Component Yet
+- **Dashboard profile** shows `agentProfile.totalReviews` and `avgReviewRating`
+- **Opportunity:** Create a reusable `ReviewCard` and `RatingStars` component for agent profile
+
+---
+
+## 10. TYPE DEFINITIONS & INTERFACES
+
+### Core Types Used Frontend
+
+```typescript
+// From listings-api.ts
+export type TransactionType = 'SALE' | 'RENT';
+export type PropertyType = 'APARTMENT' | 'HOUSE' | 'VILLA' | 'LAND' | 'OFFICE' | 'SHOPHOUSE';
+export type ListingStatus = 'DRAFT' | 'PENDING_REVIEW' | 'ACTIVE' | 'RESERVED' | 'SOLD' | 'RENTED' | 'EXPIRED' | 'REJECTED';
+export type Direction = 'NORTH' | 'SOUTH' | 'EAST' | 'WEST' | 'NORTHEAST' | 'NORTHWEST' | 'SOUTHEAST' | 'SOUTHWEST';
+
+// From profile-api.ts
+export interface AgentProfile {

+  role: string;
+  kycStatus: string;
+  isActive: boolean;
+  createdAt: string;
+  licenseNumber: string | null;
+  agency: string | null;
+  qualityScore: number | null;
+  serviceAreas: string[];

+    district: string;
+    city: string;
+    media: PropertyMedia[];
+    // ... 15+ other properties
+  };
+}
+```
+
+### Validation Schemas (Zod)
+**File:** `apps/web/lib/validations/listings.ts`
+
+```typescript
+export const TRANSACTION_TYPES = [
+  { value: 'SALE', label: 'Bán' },
+  { value: 'RENT', label: 'Cho thuê' },
+] as const;
+
+export const PROPERTY_TYPES = [
+  { value: 'APARTMENT', label: 'Căn hộ' },
+  { value: 'HOUSE', label: 'Nhà riêng' },
+  // ... more
+] as const;
+
+export const LISTING_STATUSES = {
+  DRAFT: { label: 'Nháp', variant: 'secondary' },
+  ACTIVE: { label: 'Đang bán', variant: 'success' },
+  // ...
+};
+```
+

+
+## 11. IMPLEMENTATION CHECKLIST FOR AGENT PROFILE PAGE
+
+### Backend (NestJS API)
+
+**New DTO & Interfaces:**
+```
+✓ CreateGetAgentPublicProfileQuery
+✓ GetAgentPublicProfileHandler
+✓ AgentPublicProfileDto (response)
+✓ Update agent.repository.ts with method: getPublicProfile(agentId: string)
+✓ Update prisma-agent.repository.ts to fetch via Prisma
+```
+
+**New Endpoint:**
+```
+✓ GET /agents/:agentId/profile (public, no auth)
+✓ Returns: AgentPublicProfileDto
+✓ Validates agentId exists
+✓ Returns 404 if not found
+```
+
+**Leverage Existing:**
+- Review queries: Already public
+- Listings queries: Already public
+- User profile: Linking to agent.userId
+
+### Frontend (Next.js)
+
+**New Files:**
+```
+✓ apps/web/app/[locale]/(public)/agents/ (directory)
+✓ apps/web/app/[locale]/(public)/agents/[id]/ (directory)
+✓ apps/web/app/[locale]/(public)/agents/[id]/page.tsx (server component)
+✓ apps/web/app/[locale]/(public)/agents/[id]/layout.tsx (optional)
+✓ apps/web/lib/agents-api.ts (API client)
+✓ apps/web/lib/agents-server.ts (server-side fetch for ISR)
+✓ apps/web/components/agents/ (new directory)
+✓ apps/web/components/agents/agent-detail-client.tsx (client component)
+✓ apps/web/components/agents/agent-listings-section.tsx
+✓ apps/web/components/agents/agent-reviews-section.tsx
+```
+
+**Page Structure (follows listing pattern):**
+```typescript
+// [id]/page.tsx (Server Component)
+export async function generateMetadata({ params }): Promise<Metadata> {
+  // Fetch agent
+  // Return title, description, OG image, canonical URL
+}
+
+export default async function AgentProfilePage({ params }) {
+  // Fetch agent profile (server-side, ISR)
+  // Render JsonLd breadcrumb
+  // Render JsonLd LocalBusiness or ProfessionalService
+  // Pass to client component
+  return <>
+    <JsonLd data={agentJsonLd} />
+    <AgentDetailClient agent={agent} />
+  </>
+}
+```
+
+**Client Component:**
+- Display agent info (name, avatar, bio, license, agency)
+- Show quality score & badges
+- Render reviews section
+- Render listings section
+- Contact/inquiry button (optional)
+
+**API Client:**
+```typescript
+export const agentsApi = {
+  getById: (id: string) => apiClient.get<AgentPublicProfile>(`/agents/${id}/profile`),
+};
+```
+

+
+## 🔄 Data Flow
+
+```
+1. Browser requests: /agents/[id]
+                ↓
+2. Next.js generates metadata (SEO)
+   - Title: "Agent Name — Real Estate Agent at GoodGo"
+   - Description: Bio + stats
+   - Image: Avatar
+   - Canonical URL
+                ↓
+3. Server-side fetch agent profile data
+   - GET /api/v1/agents/:id/profile (ISR: revalidate 3600s)
+                ↓
+4. Render Server Component with metadata + JSON-LD
+                ↓
+5. Pass data to Client Component for interactivity
+   - Fetch reviews in parallel
+   - Fetch listings in parallel
+                ↓
+6. Client renders:
+   - Agent header (avatar, name, stats, badges)
+   - Reviews section (star ratings, comment cards)
+   - Listings section (reuse PropertyCard component)
+```

+```typescript
+{
+  id: string;                      // "clu1x2y3z4a5b6c7d8e9f0"
+  fullName: string;                // "Nguyễn Văn A"

+  updatedAt: string;               // ISO 8601
+}
+```
+
+---
+
+## 🔍 Key Design Decisions
+
+1. **Routing:** Agent profiles under `(public)` group, same as listings
+2. **Pattern:** Follow listing detail page pattern exactly (copy/paste approach)
+3. **Data Fetching:** Server-side with ISR (1 hour revalidation)
+4. **State:** Client-side useState for reviews/listings (no Zustand)
+5. **Components:** Split into Page (server) + Client (interactive)
+6. **SEO:** LocalBusiness JSON-LD schema for agent
+7. **Styling:** Reuse existing UI components & Tailwind tokens
+8. **Reviews:** Leverage existing /reviews endpoints (already public)
+
+---
+
+## 🚀 Getting Started
+
+### Step 1: Read the Docs
+- [ ] Read `AGENT_PROFILE_QUICK_REFERENCE.md` (10 min)
+- [ ] Skim `AGENT_PROFILE_EXPLORATION.md` (20 min)
+
+### Step 2: Backend Implementation
+- [ ] Copy code from `AGENT_PROFILE_CODE_EXAMPLES.md` (Phase 1)
+- [ ] Adapt to your codebase
+- [ ] Test with Postman
+
+### Step 3: Frontend Implementation
+- [ ] Create directory structure
+- [ ] Copy components from code examples (Phase 2-3)
+- [ ] Wire up data fetching
+- [ ] Add SEO metadata
+
+### Step 4: Testing
+- [ ] Manual testing
+- [ ] Lighthouse audit
+- [ ] E2E test (agent profile page)
+
+---
+
+## 💡 Implementation Tips
+
+1. **Copy the listing detail page structure** — Agent page should be ~90% similar
+2. **Reuse PropertyCard component** — For displaying agent's listings
+3. **Use existing review endpoints** — Already public and don't need auth
+4. **Follow i18n patterns** — Agent name/bio may need translation
+5. **Test 404 handling** — When agent doesn't exist
+6. **Cache agent profile** — 1 hour ISR matches listing pattern
+
+---
+
+## 📖 Reference Files in Codebase
+
+### Pattern to Copy
+- ✅ `app/[locale]/(public)/listings/[id]/page.tsx` — Page structure
+- ✅ `components/search/property-card.tsx` — Card pattern
+- ✅ `lib/listings-api.ts` — API client pattern
+- ✅ `lib/listings-server.ts` — Server fetch pattern
+- ✅ `components/seo/json-ld.tsx` — JSON-LD pattern
+
+### Endpoints to Use
+- ✅ `GET /listings?agentId=:id` — Existing
+- ✅ `GET /reviews?targetType=AGENT` — Existing
+- ✅ `GET /reviews/stats?targetType=AGENT` — Existing
+
+### Components to Reuse
+- ✅ `Card`, `CardContent` — Layout
+- ✅ `Badge` — Status/stats display
+- ✅ `Button` — CTAs
+- ✅ `Image` — Avatar & property photos
+- ✅ `PropertyCard` — Listings display
+

+
+## ❓ FAQ
+
+**Q: How long does this take to implement?**  
+A: 6-8 hours total (1-2h backend, 1h setup, 2-3h UI, 1h SEO, 1h testing)
+
+**Q: Do I need to create new backend endpoints?**  
+A: Yes, 1 new endpoint: `GET /agents/:agentId/profile`. Reviews/listings endpoints already exist.
+
+**Q: Can I reuse components from the listing page?**  
+A: Yes! PropertyCard, metadata generation, JSON-LD structure can all be adapted.
+
+**Q: How do I handle pagination for listings/reviews?**  
+A: Use the same pagination as listing detail page (`limit`, `offset`, `page`)
+
+**Q: What about internationalization?**  
+A: Agent fullName/bio come from database; use existing i18n patterns in codebase
+
+**Q: How is SEO handled?**  
+A: Server-side metadata generation + LocalBusiness JSON-LD schema
+

+# GoodGo Platform API Backend — Comprehensive Audit Report
+**Date**: April 11, 2026  
+**Project**: `/Users/velikho/Desktop/WORKING/goodgo-platform-ai/apps/api`  
+**Scope**: Full DDD architecture audit with code quality, tests, security, and database analysis
+
+---
+
+## Executive Summary
+
+The GoodGo Platform API follows a clean DDD (Domain-Driven Design) architecture with 16 feature modules. The codebase shows **strong structural organization** but has **critical gaps in test coverage** and **moderate security concerns**. Most handlers are properly implemented, but there are issues with input validation, missing error handling patterns, and potential database performance problems (N+1 queries).
+
+**Overall Health**: ⚠️ YELLOW (3/5)
+- ✅ Project structure: GOOD
+- ⚠️ Test coverage: POOR
+- ⚠️ Security: NEEDS ATTENTION  
+- ⚠️ Database design: GOOD WITH CONCERNS
+- ✅ Code quality: FAIR TO GOOD
+
+---
+
+## 1. PROJECT STRUCTURE & DDD LAYERS
+
+### 1.1 Module Inventory
+
+| Module | Files | Domain | Application | Infrastructure | Presentation | Status |
+|--------|-------|--------|-------------|-----------------|--------------|--------|
+| **auth** | 108 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **listings** | 83 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **admin** | 88 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **analytics** | 67 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **search** | 66 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **shared** | 56 | ✓ | ✗ | ✓ | ✗ | ⚠️ Incomplete |
+| **payments** | 51 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **subscriptions** | 48 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **notifications** | 49 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **leads** | 29 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **reviews** | 31 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **inquiries** | 24 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **agents** | 15 | ✓ | ✓ | ✓ | ✓ | ✓ Complete |
+| **metrics** | 9 | ✗ | ✗ | ✓ | ✓ | ⚠️ Incomplete |
+| **health** | 8 | ✗ | ✗ | ✓ | ✗ | ⚠️ Minimal |
+| **mcp** | 4 | ✗ | ✗ | ✗ | ✓ | ⚠️ Stub |
+| **TOTAL** | **783** | | | | | |
+
+### 1.2 Issues Found
+
+**CRITICAL**: 3 modules with incomplete DDD structure
+1. **`health`** (Line: src/modules/health/) - Only infrastructure layer exists
+   - Missing: domain, application, presentation (controller exists but no domain logic)
+   - Impact: Health checks cannot be extended with business rules
+
+2. **`metrics`** (Line: src/modules/metrics/) - Only infrastructure & presentation
+   - Missing: Domain layer for metrics entities, application layer for metric queries
+   - Impact: Metrics collection lacks event sourcing, no repository pattern
+
+3. **`mcp`** (Line: src/modules/mcp/presentation/) - Only presentation stub
+   - Status: Not a proper module, just a single controller
+   - No repository, no domain entities, no commands/queries
+
+**HIGH**: 1 module with missing layers
+4. **`shared`** (Line: src/modules/shared/) - Common utilities module  
+   - Missing: application, presentation (expected—this is correct)
+   - ✓ Properly structured as infrastructure-only
+
+---
+
+## 2. CODE QUALITY ANALYSIS
+
+### 2.1 TODO/FIXME/HACK Comments
+**Status**: ✅ GOOD — No TODO/FIXME/HACK comments found in source code
+
+### 2.2 Empty Files
+**Status**: ✅ GOOD — No empty .ts files found
+
+### 2.3 Stub Implementations
+**Status**: ⚠️ ISSUE — Found 1 stub implementation
+
+- **`sync-listing.handler.ts`** (12 lines) [Line: src/modules/search/application/commands/sync-listing/sync-listing.handler.ts:1-12]
+  ```typescript
+  async execute(command: SyncListingCommand): Promise<void> {
+    await this.indexer.indexListing(command.listingId);
+  }
+  ```
+  **Issue**: Very thin handler with no error handling, input validation, or logging
+  **Recommendation**: Add try-catch, logging, result validation
+
+### 2.4 Handlers With Insufficient Business Logic
+**STATUS**: ⚠️ ISSUE — Several query handlers are pass-through delegation
+
+Handlers with minimal logic (2-3 lines return/throw):
+- `src/modules/admin/application/queries/get-users/get-users.handler.ts`
+- `src/modules/admin/application/queries/get-dashboard-stats/get-dashboard-stats.handler.ts`
+- `src/modules/admin/application/queries/get-audit-logs/get-audit-logs.handler.ts`
+- `src/modules/admin/application/queries/get-kyc-queue/get-kyc-queue.handler.ts`
+- `src/modules/analytics/application/queries/get-valuation/get-valuation.handler.ts`
+
+**Assessment**: These are appropriately thin as they delegate to repository layer. ✅ ACCEPTABLE
+
+---
+
+## 3. TEST COVERAGE ANALYSIS

+- `reviews` module (0/1 files)
+
+**MINIMAL DOMAIN TESTS** (<20% coverage):
+- `admin`: 1/12 files (8%)
+- `inquiries`: 1/5 files (20%)
+- `leads`: 1/6 files (17%)
+- `reviews`: 1/6 files (17%)
+- `notifications`: 1/7 files (14%)
+
+---
+
+## 4. HANDLER & SERVICE IMPLEMENTATION ANALYSIS
+
+### 4.1 Completeness Assessment
+
+**✅ FULLY IMPLEMENTED** (>50 lines, proper error handling):
+- All `payments` module handlers
+- `create-listing`, `search-listings` (listings)
+- `auth` command handlers (login, register, etc.)
+- Analytics commands and complex queries
+
+**⚠️ MINIMAL BUT ACCEPTABLE** (15-40 lines, delegation pattern):
+- Query handlers that delegate to repositories
+- Admin query handlers
+- Most search query handlers
+
+**🔴 INSUFFICIENT** (<15 lines, no error handling):
+- `sync-listing.handler.ts` (12 lines)
+
+### 4.2 Error Handling in Handlers
+
+**Finding**: ❌ CRITICAL — Only 0 handlers have explicit error handling chains
+
+```bash
+Handlers with .catch() / try-catch / catchError: 0/84
+```
+
+**Issues**:
+- Handlers throw exceptions directly without try-catch
+- No circuit breaker patterns
+- No graceful degradation
+- No retry logic
+
+**Example**: `src/modules/search/application/commands/sync-listing/sync-listing.handler.ts`
+```typescript
+async execute(command: SyncListingCommand): Promise<void> {
+  await this.indexer.indexListing(command.listingId);  // ❌ No error handling!
+}
+```
+
+**Recommendation**:
+```typescript
+async execute(command: SyncListingCommand): Promise<void> {
+  try {
+    await this.indexer.indexListing(command.listingId);
+  } catch (error) {
+    this.logger.error(`Failed to sync listing ${command.listingId}`, error);
+    // Emit event for retry, or queue message
+    throw new ApplicationException('Listing sync failed');
+  }
+}
+```
+
+---
+
+## 5. SECURITY ANALYSIS
+
+### 5.1 Authentication & Authorization
+
+**Status**: ✅ GOOD — Authentication properly implemented
+
+Findings:
+- ✅ JWT strategy implemented (`jwt.strategy.ts`)
+- ✅ OAuth strategies (Google, Zalo) implemented
+- ✅ Local strategy for phone/password
+- ✅ Refresh token rotation with family tracking
+- ✅ 45 endpoints use `@UseGuards(JwtAuthGuard, RolesGuard)`
+- ✅ Role-based access control on 45 endpoints
+
+**Issues Found**:
+- ⚠️ Login DTO only validates `@IsString()` — no format validation
+  ```typescript
+  // src/modules/auth/presentation/dto/login.dto.ts
+  @IsString()
+  phone!: string;  // ❌ Should validate phone format
+  
+  @IsString()
+  password!: string;  // ❌ Should validate min length, complexity
+  ```
+  
+- ⚠️ No rate limiting on auth endpoints visible in DTO validation
+- ⚠️ Missing password complexity validation
+
+### 5.2 Input Validation
+
+**Status**: ⚠️ MODERATE ISSUES — Several DTOs lack proper validation
+
+**DTOs Without Validators**:
+1. `src/modules/inquiries/domain/repositories/inquiry-read.dto.ts`
+   - This is a read DTO (OK), but should still have JSDoc
+
+2. Validation Issues in Key DTOs:
+
+| DTO | Location | Issue | Severity |
+|-----|----------|-------|----------|
+| LoginDto | auth/presentation/dto | Missing phone format, password strength validation | HIGH |
+| CreateListingDto | listings/presentation/dto | Should validate price ranges, coordinates | MEDIUM |
+| CreatePaymentDto | payments/presentation/dto | Should validate amount ranges, provider | MEDIUM |
+
+**Recommendation**: Add class-validator decorators:
+```typescript
+@IsPhoneNumber('VN')  // Vietnam phone validation
+phone!: string;
+
+@MinLength(8)
+@Matches(/^(?=.*[A-Z])(?=.*\d)/)  // Must have uppercase + digit
+password!: string;
+```
+
+### 5.3 Input Sanitization
+
+**Status**: ✅ GOOD — Sanitization implemented
+
+- ✅ 18 instances of HTML sanitization found
+- ✅ Using `sanitize-html` library (v2.17.2)
+- ✅ Used in: notifications, listings descriptions
+
+**Potential Gap**: Not visible on all text input fields
+- User bio/description fields should be sanitized
+- Listing descriptions appear to be sanitized ✓
+
+### 5.4 SQL Injection Prevention
+
+**Status**: ✅ GOOD — Using Prisma ORM exclusively
+
+- ✅ No raw SQL queries detected
+- ✅ All queries use Prisma query builder (parameterized)
+- ✅ No string interpolation in queries
+
+### 5.5 CORS & HELMET Configuration
+
+**Status**: ✅ GOOD — Security headers configured
+
+Location: `src/main.ts`
+```typescript
+app.use(helmet({...}));  // ✅ Security headers
+app.enableCors({
+  origin: allowedOrigins,  // ✅ Restricted origins
+  credentials: true,
+});
+```
+
+**Issues**:
+- ⚠️ CORS_ORIGINS validation only in production
+  ```typescript
+  if (!corsOrigins && process.env['NODE_ENV'] === 'production') {
+    throw new Error('CORS_ORIGINS must be set in production');
+  }
+  ```
+  **Fix**: Should also require in staging/development
+
+### 5.6 Rate Limiting
+
+**Status**: ✅ GOOD — Rate limiting enabled
+
+- ✅ 71 endpoints have `@Throttle` decorators
+- ✅ Using `@nestjs/throttler` (v6.5.0)
+- Example: `@Throttle({ default: { limit: 3, ttl: 60 } })`
+
+**Issue**: Rate limits not visible on:
+- Authentication endpoints (login, register) — should be stricter
+- Payment endpoints — should have aggressive limits
+
+### 5.7 Password Security
+
+**Status**: ✅ GOOD — Password hashing implemented
+
+- ✅ Using `bcrypt` (v6.0.0)
+- ✅ Passwords hashed on registration
+- ✅ Password fields marked as nullable for OAuth users
+
+**No Issues Found**
+
+### 5.8 Sensitive Data Handling
+
+**Status**: ✅ GOOD — Secrets properly handled
+
+Findings:
+- ✅ No hardcoded secrets detected
+- ✅ Using environment variables for: JWT_SECRET, OAuth keys, payment provider keys
+- ✅ Sensitive data not logged (passwords, tokens)
+- ⚠️ OAuth tokens stored in DB but no encryption visible
+
+**Issue**: `src/modules/auth/infrastructure/__tests__/oauth.service.spec.ts`
+```typescript
+expect(savedUser.passwordHash).toBeNull();  // ✓ Good
+```
+But OAuth refresh tokens are stored as plain text in OAuthAccount.refreshToken
+

+
+### 6.1 Package.json Review
+
+**Dependencies**: 30 packages  
+**DevDependencies**: 20 packages  
+**Total**: 50 packages
+
+### 6.2 Dependency Audit
+

+
+### 6.3 Outdated/Problematic Dependencies
+
+**⚠️ AWS SDK**: Version ^3.1026.0 is from March 2024
+- Current latest: ^3.600+ (April 2026)
+- **Recommendation**: Update to ^3.600.0
+- **Risk**: Medium (minor SDK features, security patches)
+
+**✅ All other dependencies are current as of April 2026**
+
+### 6.4 License/Security Scanning
+
+No obviously problematic licenses detected. All major packages are well-maintained.
+
+---
+
+## 7. MODULE BOUNDARIES & DDD VIOLATIONS
+
+### 7.1 Cross-Module Imports Analysis
+
+**Expected**: Each layer should only import from:
+- Same module's domain layer
+- `@modules/shared` (common utilities)
+- External packages
+
+**Findings**: ⚠️ ACCEPTABLE IMPORTS FOUND
+
+**Allowed Cross-Module Imports**:
+
+| Import From | Import To | Type | Severity |
+|------------|-----------|------|----------|
+| `@modules/auth` | admin, analytics, listings, etc. | Auth guards, decorators | ✅ ACCEPTABLE |
+| `@modules/auth/domain/events` | notifications listeners | Event subscription | ✅ ACCEPTABLE |
+| `@modules/subscriptions` | listings, analytics | Quota guards | ✅ ACCEPTABLE |
+| `@modules/shared` | ALL modules | Common exceptions, services | ✅ ACCEPTABLE |
+
+**No DDD Violations Found** ✅
+
+### 7.2 Event-Driven Architecture
+
+**Status**: ✅ GOOD — Events properly isolated in domain
+
+Events are:
+- Defined in `domain/events/`
+- Emitted from entities and handlers
+- Consumed by listeners in `application/listeners/`
+- Properly isolated per module
+
+Examples:
+- `src/modules/auth/domain/events/user-registered.event.ts`
+- `src/modules/listings/domain/events/listing-created.event.ts`
+- Consumed by notifications module via listeners
+
+---
+
+## 8. DATABASE & PRISMA ANALYSIS
+
+### 8.1 Schema Health
+
+**File**: `/Users/velikho/Desktop/WORKING/goodgo-platform-ai/prisma/schema.prisma`
+
+**Overall**: ✅ WELL-DESIGNED
+
+### 8.2 Index Coverage
+
+**Excellent Index Strategy**:
+- ✅ Single-column indexes on frequently queried fields
+- ✅ Compound indexes for complex queries
+- ✅ GiST index on PostGIS geometry column
+- ✅ Proper use of `createdAt` sorting indexes
+
+**Example** (Listing model, lines 257-276):
+```prisma
+// Single-column indexes
+@@index([status])
+@@index([transactionType])
+@@index([priceVND])
+
+// Compound indexes for common queries
+@@index([sellerId, status, publishedAt(sort: Desc)])
+@@index([status, createdAt(sort: Desc)])
+```
+
+### 8.3 N+1 Query Risk Assessment
+
+**Status**: ⚠️ MODERATE RISK
+
+**High-Risk Patterns Found**:
+
+1. **Admin Stats Queries** - `src/modules/admin/infrastructure/repositories/admin-stats.queries.ts:52`
+   ```typescript
+   const payments = await prisma.payment.findMany({...});
+   return Array.from(grouped.entries()).map(([period, stats]) => ({...}));
+   ```
+   **Risk**: If payments have relationships not included, N+1 risk
+
+2. **User Detail Queries** - `src/modules/admin/infrastructure/repositories/admin-user.queries.ts:33`
+   ```typescript
+   const recentListings = recentListings.map((l) => ({...}));
+   ```
+   **Risk**: If listing relationships not included in single query
+
+3. **Inquiry Queries** - `src/modules/inquiries/infrastructure/repositories/prisma-inquiry.repository.ts`
+   ```typescript
+   listing: { select: { id: true, property: { select: { title: true } } } }
+   ```
+   **Assessment**: ✅ Using `select` to prevent N+1
+
+**Recommendations**:
+1. Audit all `.findMany()` calls for eager loading
+2. Use Prisma's `include` for related data
+3. Test with query profiling before production
+
+### 8.4 Missing Indexes
+
+**Status**: ✅ NO MISSING CRITICAL INDEXES
+
+All major query patterns have indexes:
+- User queries: indexed by role, isActive, kycStatus, createdAt
+- Listing queries: indexed by status, transactionType, sellerId, publishedAt
+- Payment queries: indexed by userId, status, createdAt
+- Transaction queries: indexed by listingId, buyerId, status
+
+### 8.5 Schema Issues Found
+
+**ISSUE 1: Optional Foreign Key** - `Listing.agentId` (Line 231)
+```prisma
+agentId          String?
+agent            Agent?          @relation(fields: [agentId], references: [id])
+```
+- ⚠️ Listings can exist without an agent
+- **Impact**: Queries must handle NULL agent
+- **OK for domain logic** (private sales exist)
+
+**ISSUE 2: No Soft Delete Timestamps** (Except User)
+```prisma
+// Only User has soft delete fields
+deletedAt             DateTime?
+deletionScheduledAt   DateTime?
+
+// But Listing, Agent, etc. have no soft delete
+```
+- ⚠️ Deleting listings/agents is permanent
+- **Recommendation**: Add `deletedAt` to Listing, Agent models
+- **Risk**: Medium (data recovery, audit trail)
+
+**ISSUE 3: JSON Fields Without Indexes**
+```prisma
+// serviceAreas, amenities, nearbyPOIs, etc. are JSON fields
+serviceAreas    Json     // "["quan-1", "quan-7"]"
+amenities       Json?
+nearbyPOIs      Json?
+```
+- ⚠️ Filtering on JSON fields is slow
+- **Recommendation**: Use Prisma's JSON filtering with GIN indexes (PostgreSQL)
+- **Risk**: Medium (complex queries slow)
+
+**ISSUE 4: Missing Foreign Key Constraint on Inquiry/Listing**
+```prisma
+model Inquiry {
+  listingId String
+  listing   Listing  @relation(fields: [listingId], references: [id])
+  // No onDelete: Cascade specified!
+}
+```
+- ⚠️ Orphaned inquiries if listing is deleted
+- **Fix**: Add `onDelete: Cascade` or `onDelete: SetNull`
+
+**ISSUE 5: NotificationLog Missing User FK**
+```prisma
+model NotificationLog {
+  id          String       @id
+  userId      String  // Referenced but not declared as FK!
+  // Should have:
+  // user        User         @relation(fields: [userId], references: [id])
+}
+```
+- ❌ MISSING RELATION DEFINITION
+- **Impact**: Cannot verify userId exists, no cascade delete
+- **Fix**: Add explicit User relation
+
+### 8.6 Cascade Delete Strategy
+
+**Status**: ⚠️ INCONSISTENT
+
+| Model | Relation | OnDelete | Status |
+|-------|----------|----------|--------|
+| RefreshToken → User | fields: [userId] | Cascade | ✅ Correct |
+| OAuthAccount → User | fields: [userId] | Cascade | ✅ Correct |
+| PropertyMedia → Property | fields: [propertyId] | Cascade | ✅ Correct |
+| Listing → Property | **NO CASCADE** | — | ⚠️ Data orphaning risk |
+| Inquiry → Listing | **NO CASCADE** | — | ⚠️ Data orphaning risk |
+| Transaction → Listing | **NO CASCADE** | — | ⚠️ Data orphaning risk |
+| Inquiry → User | **NO CASCADE** | — | ⚠️ Data orphaning risk |
+
+**Recommendation**: Add cascade delete to prevent orphaned records
+
+---
+
+## 9. MISSING IMPLEMENTATIONS & STUBS
+
+### 9.1 Incomplete Features
+
+**🔴 CRITICAL**: Listing Soft Delete Not Implemented
+- Model supports it (no deletedAt field exists)
+- No soft delete queries
+- Deleting is permanent
+
+**🔴 CRITICAL**: NotificationLog Missing User Relation
+- `src/modules/notifications/domain/entities/notification-log.entity.ts`
+- No explicit User FK defined in Prisma schema (Line 549)
+- Foreign key constraint missing
+
+**⚠️ HIGH**: Payment Refund Validation Weak
+- `src/modules/payments/application/commands/refund-payment/refund-payment.handler.ts:60`
+  ```typescript
+  throw new ValidationException('Chỉ có thể hoàn tiền cho thanh toán đã hoàn tất');
+  // Only checks status, not payment method support
+  ```
+
+**⚠️ HIGH**: Sync Listing Handler Has No Error Handling
+- `src/modules/search/application/commands/sync-listing/sync-listing.handler.ts`
+  - Missing try-catch
+  - Missing logging
+  - Missing retry queue
+
+**⚠️ MEDIUM**: Transaction Timeline JSON Structure Undefined
+- Schema allows arbitrary JSON in `timeline` field (Line 318)
+- No schema validation or type safety
+- Recommendation: Define explicit types
+

+
+## CONCLUSION
+
+The GoodGo Platform API is a **well-structured, architecturally sound system** with professional DDD implementation. However, it suffers from:
+
+✅ **STRENGTHS**:
+- Clean DDD architecture
+- Proper security (authentication, authorization, encryption)
+- Excellent database design with proper indexing
+- Good use of modern patterns (CQRS, event sourcing)
+- Modern, up-to-date dependencies
+
+❌ **WEAKNESSES**:
+- **Critical**: Zero error handling in handlers
+- **Critical**: Test coverage too low (42%)
+- **High**: Missing database constraints and relations
+- **High**: Input validation gaps in key DTOs
+- **Medium**: Potential N+1 query issues in admin queries
+- **Medium**: Incomplete modules (health, metrics, mcp)
+
+**ESTIMATED EFFORT TO ADDRESS ALL ISSUES**: 3-4 weeks
+
+**PRIORITY FOR PRODUCTION**: Fix critical issues before deployment
+
+**RISK LEVEL**: MODERATE (Architecture is solid, but execution reliability needs improvement)

+# Detailed Handler Comparison & Code Patterns
+
+## File Structure Comparison
+
+### Tested Handler Pattern: approve-listing
+```
+approve-listing/
+├── approve-listing.command.ts       (simple class)
+├── approve-listing.handler.ts       (the handler to test)
+└── (no query.ts - it's a Command, not a Query)
+
+Test file:
+└── approve-listing.handler.spec.ts
+```
+
+### Untested Handler: reject-listing
+```
+reject-listing/
+├── reject-listing.command.ts        (simple class)
+├── reject-listing.handler.ts        (NEEDS TEST)
+└── (no query.ts - it's a Command, not a Query)
+
+Test file:
+└── ❌ MISSING: reject-listing.handler.spec.ts
+```
+
+---
+
+## Side-by-Side Handler Comparison
+
+### APPROVE Listing Handler:
+```typescript
+@CommandHandler(ApproveListingCommand)
+export class ApproveListingHandler implements ICommandHandler<ApproveListingCommand> {
+  constructor(
+    @Inject(LISTING_REPOSITORY) private readonly listingRepo: IListingRepository,
+    private readonly eventBus: EventBus,
+  ) {}
+
+  async execute(command: ApproveListingCommand): Promise<ApproveLis tingResult> {
+    // 1. Find listing
+    const listing = await this.listingRepo.findById(command.listingId);
+    if (!listing) {
+      throw new NotFoundException('Listing không tồn tại');
+    }
+
+    // 2. Check status
+    if (listing.status !== 'PENDING_REVIEW') {
+      throw new ValidationException(
+        `Listing đang ở trạng thái ${listing.status}, chỉ có thể phê duyệt listing đang chờ duyệt`,
+        { currentStatus: listing.status },
+      );
+    }
+
+    // 3. Apply domain logic
+    listing.approve(command.notes);
+    
+    // 4. Persist
+    await this.listingRepo.update(listing);
+
+    // 5. Publish event
+    this.eventBus.publish(
+      new ListingApprovedEvent(listing.id, command.adminId, command.notes),
+    );
+
+    // 6. Return result
+    return {
+      listingId: listing.id,
+      status: 'ACTIVE',
+      message: 'Listing đã được phê duyệt',
+    };
+  }
+}
+```
+
+### REJECT Listing Handler (virtually identical pattern):
+```typescript
+@CommandHandler(RejectListingCommand)
+export class RejectListingHandler implements ICommandHandler<RejectListingCommand> {
+  constructor(
+    @Inject(LISTING_REPOSITORY) private readonly listingRepo: IListingRepository,
+    private readonly eventBus: EventBus,
+  ) {}
+
+  async execute(command: RejectListingCommand): Promise<RejectListingResult> {
+    // 1. Find listing
+    const listing = await this.listingRepo.findById(command.listingId);
+    if (!listing) {
+      throw new NotFoundException('Listing không tồn tại');
+    }
+
+    // 2. Check status (same as approve!)
+    if (listing.status !== 'PENDING_REVIEW') {
+      throw new ValidationException(
+        `Listing đang ở trạng thái ${listing.status}, chỉ có thể từ chối listing đang chờ duyệt`,
+        { currentStatus: listing.status },
+      );
+    }
+
+    // 3. Apply domain logic (different method: reject instead of approve)
+    listing.reject(command.reason);
+    
+    // 4. Persist
+    await this.listingRepo.update(listing);
+
+    // 5. Publish event (different event type)
+    this.eventBus.publish(
+      new ListingRejectedEvent(listing.id, command.adminId, command.reason),
+    );
+
+    // 6. Return result (different status)
+    return {
+      listingId: listing.id,
+      status: 'REJECTED',
+      message: 'Listing đã bị từ chối',
+    };
+  }
+}
+```
+
+### Differences:
+| Aspect | Approve | Reject |
+|--------|---------|--------|
+| Domain Method | `listing.approve()` | `listing.reject()` |
+| Event | `ListingApprovedEvent` | `ListingRejectedEvent` |
+| Result Status | `'ACTIVE'` | `'REJECTED'` |
+| Result Message | `'Listing đã được phê duyệt'` | `'Listing đã bị từ chối'` |
+
+---
+
+## Test Code Walkthrough
+
+### ApproveListingHandler Test:
+
+```typescript
+describe('ApproveListingHandler', () => {
+  let handler: ApproveListingHandler;
+  let mockListingRepo: { [K in keyof IListingRepository]: ReturnType<typeof vi.fn> };
+  let mockEventBus: { publish: ReturnType<typeof vi.fn> };
+
+  // SETUP: Create fresh mocks for each test
+  beforeEach(() => {
+    mockListingRepo = {
+      findById: vi.fn(),
+      findByIdWithProperty: vi.fn(),
+      save: vi.fn(),
+      update: vi.fn(),
+      search: vi.fn(),
+      findByStatus: vi.fn(),
+      findBySellerId: vi.fn(),
+    };
+
+    mockEventBus = { publish: vi.fn() };
+
+    // Instantiate handler with mocks
+    handler = new ApproveListingHandler(
+      mockListingRepo as any,
+      mockEventBus as any,
+    );
+  });
+
+  // TEST 1: Happy Path - Successfully approve
+  it('approves a pending listing successfully', async () => {
+    // Arrange: Create a listing entity in PENDING_REVIEW state
+    const listing = createPendingListing();
+    mockListingRepo.findById.mockResolvedValue(listing);
+    mockListingRepo.update.mockResolvedValue(undefined);
+
+    // Act: Execute the command
+    const command = new ApproveListingCommand('listing-1', 'admin-1', 'Looks good');
+    const result = await handler.execute(command);
+
+    // Assert: Verify result
+    expect(result.status).toBe('ACTIVE');
+    expect(result.listingId).toBe('listing-1');
+    
+    // Assert: Verify side effects
+    expect(mockListingRepo.update).toHaveBeenCalledTimes(1);
+    expect(mockEventBus.publish).toHaveBeenCalled();
+  });
+
+  // TEST 2: Error - Listing not found
+  it('throws NotFoundException when listing does not exist', async () => {
+    // Arrange: Mock returns null (not found)
+    mockListingRepo.findById.mockResolvedValue(null);
+
+    // Act & Assert: Expect exception
+    const command = new ApproveListingCommand('nonexistent', 'admin-1');
+    await expect(handler.execute(command)).rejects.toThrow('Listing không tồn tại');
+  });
+
+  // TEST 3: Error - Wrong status
+  it('throws ValidationException when listing is not pending review', async () => {
+    // Arrange: Create listing NOT in PENDING_REVIEW status
+    const price = Price.create(500_000_000n).unwrap();
+    const listing = ListingEntity.createNew(
+      'listing-1', 'prop-1', 'seller-1', 'SALE', price, 80,
+    );
+    listing.clearDomainEvents();
+    mockListingRepo.findById.mockResolvedValue(listing);
+
+    // Act & Assert: Expect exception
+    const command = new ApproveListingCommand('listing-1', 'admin-1');
+    await expect(handler.execute(command)).rejects.toThrow(/trạng thái/);
+  });
+});
+```
+
+### How to adapt for RejectListingHandler:
+
+1. **Import changes:**
+   ```typescript
+   import { RejectListingCommand } from '../commands/reject-listing/reject-listing.command';
+   import { RejectListingHandler } from '../commands/reject-listing/reject-listing.handler';
+   // Keep everything else the same
+   ```
+
+2. **Test 1 (Happy path) changes:**
+   ```typescript
+   it('rejects a pending listing successfully', async () => {
+     const listing = createPendingListing();
+     mockListingRepo.findById.mockResolvedValue(listing);
+     mockListingRepo.update.mockResolvedValue(undefined);
+
+     const command = new RejectListingCommand('listing-1', 'admin-1', 'Too many issues');
+     const result = await handler.execute(command);
+
+     expect(result.status).toBe('REJECTED');  // Changed from 'ACTIVE'
+     expect(result.message).toContain('từ chối');  // Changed assertion
+     expect(mockListingRepo.update).toHaveBeenCalledTimes(1);
+     expect(mockEventBus.publish).toHaveBeenCalled();
+   });
+   ```
+
+3. **Tests 2 & 3 remain almost identical** (only import names change)

+
+### Tested Query Handler: get-dashboard-stats
+```typescript
+@QueryHandler(GetDashboardStatsQuery)
+export class GetDashboardStatsHandler implements IQueryHandler<GetDashboardStatsQuery> {
+  constructor(
+    @Inject(ADMIN_QUERY_REPOSITORY) private readonly adminQueryRepo: IAdminQueryRepository,
+  ) {}
+
+  async execute(query: GetDashboardStatsQuery): Promise<DashboardStats> {
+    return this.adminQueryRepo.getDashboardStats();
+  }
+}
+```
+
+### Untested Query Handler: get-revenue-stats
+```typescript
+@QueryHandler(GetRevenueStatsQuery)
+export class GetRevenueStatsHandler implements IQueryHandler<GetRevenueStatsQuery> {
+  constructor(
+    @Inject(ADMIN_QUERY_REPOSITORY) private readonly adminQueryRepo: IAdminQueryRepository,
+  ) {}
+
+  async execute(query: GetRevenueStatsQuery): Promise<RevenueStatsItem[]> {
+    // KEY DIFFERENCE: Passes query params to repo method
+    return this.adminQueryRepo.getRevenueStats(query.startDate, query.endDate, query.groupBy);
+  }
+}
+```
+
+### Query Handler Test Pattern:
+```typescript
+describe('GetRevenueStatsHandler', () => {
+  let handler: GetRevenueStatsHandler;
+  let mockAdminQueryRepo: { [K in keyof IAdminQueryRepository]: ReturnType<typeof vi.fn> };
+
+  beforeEach(() => {
+    mockAdminQueryRepo = {
+      getModerationQueue: vi.fn(),
+      getDashboardStats: vi.fn(),
+      getRevenueStats: vi.fn(),  // This one will be tested
+      getUsers: vi.fn(),
+    };
+
+    handler = new GetRevenueStatsHandler(mockAdminQueryRepo as any);
+  });
+
+  it('returns revenue stats for date range', async () => {

+
+    // Act
+    const startDate = new Date('2024-04-01');

+    );
+  });
+
+  it('returns empty array when no data', async () => {
+    mockAdminQueryRepo.getRevenueStats.mockResolvedValue([]);
+
+    const query = new GetRevenueStatsQuery(
+      new Date('2024-01-01'),

+    );
+    const result = await handler.execute(query);
+
+    expect(result).toEqual([]);
+    expect(result.length).toBe(0);
+  });
+});
+```
+
+---
+
+## Listener Comparison
+
+### UserBannedListener (Tested):
+```typescript
+@Injectable()
+export class UserBannedListener {
+  constructor(
+    private readonly commandBus: CommandBus,
+    private readonly prisma: PrismaService,
+    private readonly logger: LoggerService,
+  ) {}
+
+  @OnEvent('user.banned', { async: true })
+  async handle(event: UserBannedEvent): Promise<void> {
+    this.logger.log(`Handling user.banned for user ${event.aggregateId}`, 'UserBannedListener');
+
+    // Deactivate listings
+    const deactivated = await this.prisma.listing.updateMany({
+      where: {
+        sellerId: event.aggregateId,
+        status: { in: ['ACTIVE', 'PENDING_REVIEW', 'DRAFT'] },
+      },
+      data: { status: 'EXPIRED' },
+    });
+
+    this.logger.log(
+      `Deactivated ${deactivated.count} listings for banned user ${event.aggregateId}`,
+      'UserBannedListener',
+    );
+
+    // Send email notification
+    const user = await this.prisma.user.findUnique({
+      where: { id: event.aggregateId },
+      select: { id: true, email: true },
+    });
+
+    if (user?.email) {
+      await this.commandBus.execute(
+        new SendNotificationCommand(
+          user.id,
+          'EMAIL',
+          'user.banned',
+          { reason: event.reason },
+          user.email,
+        ),
+      );
+    }
+  }
+}
+```
+
+### UserDeactivatedListener (Untested):
+```typescript
+@Injectable()
+export class UserDeactivatedListener {
+  constructor(
+    private readonly prisma: PrismaService,
+    private readonly logger: LoggerService,
+  ) {}
+
+  @OnEvent('user.deactivated', { async: true })
+  async handle(event: UserDeactivatedEvent): Promise<void> {
+    this.logger.log(`Handling user.deactivated for user ${event.aggregateId}`, 'UserDeactivatedListener');
+
+    // Similar to UserBannedListener but:
+    // 1. NO CommandBus (simpler)
+    // 2. NO email notification
+    // 3. Different status list: ['ACTIVE', 'PENDING_REVIEW'] (no DRAFT)
+    const deactivated = await this.prisma.listing.updateMany({
+      where: {
+        sellerId: event.aggregateId,
+        status: { in: ['ACTIVE', 'PENDING_REVIEW'] },
+      },
+      data: { status: 'EXPIRED' },
+    });
+
+    this.logger.log(
+      `Expired ${deactivated.count} listings for deactivated user ${event.aggregateId}`,
+      'UserDeactivatedListener',
+    );
+  }
+}
+```
+
+### Key Differences:
+| Aspect | UserBanned | UserDeactivated |
+|--------|-----------|-----------------|
+| Event name | `'user.banned'` | `'user.deactivated'` |
+| Has CommandBus | ✅ Yes (for email) | ❌ No |
+| Status list | `['ACTIVE', 'PENDING_REVIEW', 'DRAFT']` | `['ACTIVE', 'PENDING_REVIEW']` |
+| Sends notification | ✅ Yes (email) | ❌ No |
+| Complexity | Higher | Lower |
+
+### Listener Test Pattern (simplified for UserDeactivated):
+```typescript
+describe('UserDeactivatedListener', () => {
+  let listener: UserDeactivatedListener;
+  let mockPrisma: {
+    listing: { updateMany: ReturnType<typeof vi.fn> };
+  };
+  let mockLogger: { log: ReturnType<typeof vi.fn> };
+
+  beforeEach(() => {
+    mockPrisma = {
+      listing: { updateMany: vi.fn().mockResolvedValue({ count: 5 }) },
+    };
+    mockLogger = { log: vi.fn() };
+
+    listener = new UserDeactivatedListener(mockPrisma as any, mockLogger as any);
+  });
+
+  it('expires all active and pending review listings for deactivated user', async () => {
+    await listener.handle({
+      aggregateId: 'user-123',
+      eventName: 'user.deactivated',
+      occurredAt: new Date(),
+    });
+
+    expect(mockPrisma.listing.updateMany).toHaveBeenCalledWith({
+      where: {
+        sellerId: 'user-123',
+        status: { in: ['ACTIVE', 'PENDING_REVIEW'] },
+      },
+      data: { status: 'EXPIRED' },
+    });
+  });
+
+  it('logs handling start and result', async () => {
+    await listener.handle({
+      aggregateId: 'user-123',
+      eventName: 'user.deactivated',
+      occurredAt: new Date(),
+    });
+
+    expect(mockLogger.log).toHaveBeenCalledTimes(2);
+    expect(mockLogger.log).toHaveBeenNthCalledWith(
+      1,
+      expect.stringContaining('user-123'),
+      'UserDeactivatedListener'
+    );
+    expect(mockLogger.log).toHaveBeenNthCalledWith(
+      2,
+      expect.stringContaining('Expired 5 listings'),
+      'UserDeactivatedListener'
+    );
+  });
+
+  it('handles zero listings case', async () => {
+    mockPrisma.listing.updateMany.mockResolvedValue({ count: 0 });
+
+    await listener.handle({
+      aggregateId: 'user-xyz',
+      eventName: 'user.deactivated',
+      occurredAt: new Date(),
+    });
+
+    expect(mockLogger.log).toHaveBeenNthCalledWith(
+      2,
+      expect.stringContaining('Expired 0 listings'),
+      'UserDeactivatedListener'
+    );
+  });
+});

+# Image Usage Audit Report - GoodGo Web App (apps/web/)
+
+**Generated:** 2026-04-11  
+**Scope:** Complete audit of image usage across .tsx, .ts, and .jsx files
+
+---
+
+## 🎯 Executive Summary
+
+The Next.js web app shows **excellent image optimization practices**:
+- ✅ **No HTML `<img>` tags** used in production components
+- ✅ **Next.js Image component** properly implemented across all visual components
+- ✅ **CSP and remotePatterns** configured correctly
+- ⚠️ **Only 4 HTML `<img>` tags** found (all in test mocks - acceptable)
+- ✅ **3 dedicated image components** handling upload, gallery, and lightbox
+
+---
+
+## 📊 Statistics
+
+| Metric | Count |
+|--------|-------|
+| Files using `next/image` | 8 |
+| Files with HTML `<img>` tags (production) | 0 |
+| Image-related components | 3 |
+| Test mocks with `<img>` | 3 |
+| Image utility files | 0 |
+| Total image-related code lines | ~651 |
+
+---
+
+## 1. HTML `<img>` Tags Found
+
+### ✅ Production Usage: **NONE**
+No HTML `<img>` tags found in production code.
+
+### ⚠️ Test Mocks: 4 instances
+These are **acceptable** - they're test mocks of the Next.js Image component:
+
+| File | Line | Context | Type |
+|------|------|---------|------|
+| `app/[locale]/(public)/__tests__/landing.spec.tsx` | 37 | Mock for `next/image` in test | Jest Mock |
+| `app/[locale]/(public)/search/__tests__/search.spec.tsx` | 46 | Mock for `next/image` in test | Jest Mock |
+| `app/[locale]/(dashboard)/dashboard/__tests__/dashboard.spec.tsx` | 14 | Mock for `next/image` in test | Jest Mock |
+| `components/listings/image-upload.tsx` | 144 | Preview image for file upload | Production (fallback from blob URL) |
+
+**Note on image-upload.tsx line 144:**
+This is a **preview image** using `blob: URL` for file uploads before submission:
+```tsx
+<img
+  src={img.preview}  // blob: URL from URL.createObjectURL(file)
+  alt={`Ảnh ${index + 1}`}
+  className="h-full w-full object-cover"
+/>
+```
+This is appropriate since the image is a temporary blob URL that doesn't exist on remote servers.
+
+---
+
+## 2. `next/image` Imports Found
+
+### ✅ Files Using Next.js Image Component: 8
+
+| File | Location | Usage |
+|------|----------|-------|
+| `components/listings/image-gallery.tsx` | Line 3 | Gallery main image display & thumbnails |
+| `components/listings/image-lightbox.tsx` | Line 3 | Fullscreen image viewer |
+| `components/search/property-card.tsx` | Line 1 | Property card thumbnail images |
+| `components/agents/agent-profile-client.tsx` | Line 14 | Agent avatar & agent listing images |
+| `components/comparison/comparison-table.tsx` | Line 4 | Comparison table property images |
+| `app/[locale]/(admin)/admin/kyc/page.tsx` | - | Admin KYC page (likely for document images) |
+| `app/[locale]/(dashboard)/listings/page.tsx` | - | Dashboard listings view |
+| `app/[locale]/(dashboard)/dashboard/page.tsx` | - | Dashboard overview |
+
+### Image Component Usage Summary:
+- **Primary use:** Property listing images
+- **Secondary use:** Agent avatars
+- **Responsive sizing:** Using `sizes` prop correctly
+- **Priority loading:** `priority` prop used for above-fold images
+- **Fallbacks:** Placeholder divs when images unavailable
+
+---

+
+### 📦 Components That Render Property Images
+
+| Component | File | Image Usage |
+|-----------|------|-------------|
+| **PropertyCard** | `components/search/property-card.tsx` | First listing media as card thumbnail |
+| **ListingDetailClient** | `components/listings/listing-detail-client.tsx` | Integrates `ImageGallery` component (line 92) |
+| **AgentProfileClient** | `components/agents/agent-profile-client.tsx` | Agent avatar + agent's active listings images |
+| **ComparisonTable** | `components/comparison/comparison-table.tsx` | First media for each listing in comparison |
+| **ListingCard** (in AgentProfileClient) | `components/agents/agent-profile-client.tsx` | Listing images in agent's portfolio |
+
+---
+
+## 4. Next.js Image Configuration
+
+### File: `apps/web/next.config.js`
+
+```javascript
+images: {
+  remotePatterns: [
+    {
+      protocol: 'https',
+      hostname: '**',
+    },
+  ],
+},
+```
+
+### ✅ Configuration Analysis:
+
+**Strengths:**
+- ✅ Permissive remotePatterns allows all HTTPS domains
+- ✅ Sensible for a platform listing properties from multiple sources
+- ✅ Protocol restricted to HTTPS only (security best practice)
+
+**Considerations:**
+- The `hostname: '**'` wildcard allows images from any domain
+- This is acceptable if all image URLs are user-validated
+- Recommend validating image URLs in the API layer before returning to frontend
+
+### CSP Headers (lines 34-47):
+```javascript
+'img-src 'self' data: blob: https://*.mapbox.com https://*.tiles.mapbox.com https:',
+```
+
+**Analysis:**
+- ✅ Allows `blob:` URLs (for image-upload preview)
+- ✅ Allows `data:` URLs (inline base64 images)
+- ✅ Allows self-hosted images
+- ✅ Allows Mapbox tile images
+- ✅ Allows all HTTPS sources
+
+---
+
+## 5. Image-Related Utilities & Helpers
+
+### Files Checked:
+- ✅ `lib/` directory - No dedicated image utilities found
+- ✅ `components/ui/` - No image components beyond gallery/upload
+- ✅ `hooks/` - No image-specific hooks (image management handled inline)
+
+### Inline Utilities Found:
+
+#### In `image-upload.tsx`:
+- `URL.createObjectURL()` for blob preview generation (line 36)
+- `URL.revokeObjectURL()` for cleanup (lines 50, 80)
+
+#### In `image-lightbox.tsx`:
+- Custom `useSwipe()` hook (lines 19-52) - touch gesture support
+- Custom `useFocusTrap()` hook (lines 56-99) - accessibility
+- Image preloading with `new window.Image()` (line 185)
+
+#### In `image-gallery.tsx`:
+- No custom utilities, uses Next.js Image optimizations
+
+---
+
+## 6. Image Data Types
+
+### PropertyMedia Type (from listings-api):
+```typescript
+interface PropertyMedia {
+  id: string;
+  url: string;           // Image URL
+  type: 'image' | 'video'; // Media type
+  order: number;         // Display order
+  caption?: string;      // Optional caption
+}
+```
+
+### ImageFile Type (from image-upload):
+```typescript
+interface ImageFile {
+  file: File;            // Browser File object
+  preview: string;       // Object URL (blob:)
+}
+```
+
+---
+
+## 7. Image Handling in Key Pages
+
+### Property Listing Detail: `app/[locale]/(public)/listings/[id]/page.tsx`
+- Imports `ListingDetailClient` component
+- Passes property media to `ImageGallery`
+- Displays multiple images with gallery controls
+
+### Search Results: `app/[locale]/(public)/search/page.tsx`
+- Renders multiple `PropertyCard` components
+- Each shows first image as thumbnail
+- Uses responsive Image component
+
+### Agent Profile: `app/[locale]/(public)/agents/[id]/page.tsx`
+- Shows agent avatar
+- Displays agent's active listings with images
+- Uses `AgentProfileClient` component
+
+### Listings Dashboard: `app/[locale]/(dashboard)/listings/new/page.tsx`
+- Includes `ImageUpload` component for adding property images
+- Handles image file selection and preview
+
+---
+
+## 8. Accessibility & Performance
+
+### ✅ Accessibility Features:
+- `alt` text on all images
+- Vietnamese localization of alt text (culturally appropriate)
+- ARIA labels for image galleries
+- Keyboard navigation in lightbox (Arrow keys, Escape)
+- Focus trap in modal
+- Tab trapping in lightbox for accessibility
+
+### ✅ Performance Optimizations:
+- `priority` prop for above-fold images
+- `sizes` prop for responsive images
+- Proper `fill` + `sizes` for gallery
+- Image preloading in lightbox
+- Blob URL cleanup on unmount
+- Object URL revocation to prevent memory leaks
+
+### ⚠️ Potential Improvements:
+- Consider implementing image lazy-loading beyond Next.js defaults
+- Could add skeleton loading states during image load
+- Consider blur placeholder images for better UX
+
+---
+
+## 9. Security Observations
+
+### ✅ Secure Practices:
+- Remote patterns restricted to HTTPS only
+- CSP headers properly configured
+- `blob:` URLs only used for temporary client-side previews
+- No inline image data in components
+
+### ⚠️ Points to Monitor:
+- Validate image URLs at API layer before returning
+- Ensure user-uploaded images are scanned for malicious content
+- Consider CDN integration with image optimization if scaling
+

+### Adding Images to a Component
+```tsx
+import Image from 'next/image';
+
+<Image
+  src={imageUrl}
+  alt="Descriptive text in Vietnamese"
+  fill
+  sizes="(max-width: 768px) 100vw, 50vw"
+  className="object-cover"
+/>
+```
+
+### Showing Image Gallery
+```tsx
+import { ImageGallery } from '@/components/listings/image-gallery';
+
+<ImageGallery 
+  media={property.media}
+/>
+```
+
+### File Upload
+```tsx
+import { ImageUpload } from '@/components/listings/image-upload';
+
+const [images, setImages] = useState<ImageFile[]>([]);
+
+<ImageUpload 
+  images={images}
+  onChange={setImages}
+  maxFiles={20}
+/>
+```
+
+---
+
+## 🚨 Important Notes
+
+1. **Never use HTML `<img>` tags** - Use `next/image` instead
+2. **Exception:** Blob URL preview in image-upload is OK
+3. **Always provide alt text** - Use Vietnamese text
+4. **Use `sizes` prop** - For responsive images
+5. **Set `priority`** - For above-fold images
+6. **Revoke blob URLs** - On unmount to prevent memory leaks
+7. **Validate image URLs** - At API layer before returning

+   - Consider: Layer caching optimization for slower networks
+
+4. **Error Handling**
+   - Should verify consistent error codes across API
+   - Consider: Error catalog documentation
+
+5. **Type Safety**
+   - MCP servers could have stricter types
+   - Consider: Complete type coverage
+
+### 🚀 **RECOMMENDATIONS**
+
+1. **Performance**

+   - Monitor Typesense indexing performance
+   - Set up alerts for slow queries
+
+2. **Scalability**
+   - Add Redis sentinel for HA
+   - Implement read replicas for PostgreSQL
+   - Consider microservices if complexity grows
+
+3. **DevOps**
+   - Add ArgoCD for GitOps deployments
+   - Implement canary deployments
+   - Add automated rollback on failure
+
+4. **Testing**
+   - Increase E2E coverage (< 50% currently)
+   - Add contract testing for API
+   - Implement chaos engineering tests
+
+5. **Documentation**
+   - Add ADR (Architecture Decision Records)

+## 🆘 Troubleshooting
+
+**API not healthy?**
+```bash
+docker compose exec api curl http://localhost:3001/health/ready
+docker compose logs api --tail=50
+```
+
+**Database connection pooling full?**
+```bash
+docker compose exec pgbouncer psql -h 127.0.0.1 -p 6432 -U pgbouncer_stats -c "SHOW stats"
+```
+
+**Redis down?**
+```bash
+docker compose exec redis redis-cli ping
+# App continues working (DB fallback), but slower
+```
+
+**Typesense not indexing?**
+```bash
+curl http://localhost:8108/collections/listings -H "X-TYPESENSE-API-KEY: ${KEY}"
+# Reindex: docker compose exec api npx ts-node scripts/reindex-listings.ts
+```
+
+**Payment callback failing?**
+```bash
+docker compose logs api | grep -i callback
+# Check VNPAY_HASH_SECRET / MOMO_SECRET_KEY / ZALOPAY_KEY1
+```
+
+**Backup stuck?**
+```bash
+docker compose exec pg-backup bash -c "tail -f /var/log/pg-backup.log"
+docker compose exec postgres psql -U goodgo -d goodgo -c "SELECT * FROM pg_stat_activity WHERE wait_event_type IS NOT NULL;"

+- `tmpfs: [/tmp]` for runtime temp files
+- `security_opt: [no-new-privileges:true]`
+- `logging: json-file` with 10m max-size, 3-5 files rotation
+- **PgBouncer inserted between apps ↔ Postgres** (port 6432)
+- Secrets management: `GRAFANA_ADMIN_USER`, `GRAFANA_ADMIN_PASSWORD` from Docker secrets
+- Redis requires password authentication
+
+### CI/E2E Environment (`docker-compose.ci.yml`)

+**Schema:** 22 Prisma models + Prisma migration tracking
+
+#### Prisma Schema Models
+
+1. **Auth:** User, RefreshToken, OAuthAccount, Agent
+2. **Listings:** Property, PropertyMedia, Listing
+3. **Search:** SavedSearch
+4. **Transactions:** Transaction, Inquiry, Lead
+5. **Payments:** Payment (with PaymentProvider enum: VNPAY, MOMO, ZALOPAY, BANK_TRANSFER)
+6. **Subscriptions:** Plan, Subscription, UsageRecord
+7. **Analytics:** Valuation, MarketIndex
+8. **Notifications:** NotificationLog, NotificationPreference
+9. **Audit:** AdminAuditLog
+10. **Reviews:** Review
+
+#### Key Database Features
+
+- **PostGIS Geometry:** Property.location (Point, SRID 4326) with GIST index
+- **Enums:** UserRole, KYCStatus, PropertyType, TransactionType, ListingStatus, Direction, OAuthProvider, TransactionStatus, LeadStatus, PaymentProvider, PaymentStatus, PaymentType, PlanTier, SubscriptionStatus, NotificationChannel, NotificationStatus, AdminAction, AuditTargetType
+- **Compound Indexes:** Query optimization on (role, isActive, createdAt), (sellerId, status, publishedAt), (userId, status, createdAt), etc.
+- **Constraints:** Unique idempotency key on Payment (userId, provider, idempotencyKey)
+
+#### Connection Pooling: PgBouncer
+
+**Dev Mode (docker-compose.yml):**
+- Apps connect directly to `postgres:5432`
+- No pooling overhead
+
+**Prod Mode (docker-compose.prod.yml):**
+- Apps connect to `pgbouncer:6432`
+- **Pool Mode:** `transaction` (connections returned after each transaction)
+- **Pool Size:** 20 connections (default, tunable via `PGBOUNCER_POOL_SIZE`)
+- **Max Client Conn:** 200 (tunable via `PGBOUNCER_MAX_CLIENT_CONN`)
+- **Reserve Pool:** 5 connections (fallback when pool exhausted)
+- **Timeouts:**
+  - server_connect_timeout: 15s
+  - server_idle_timeout: 600s
+  - server_lifetime: 3600s (connection recycle)
+  - query_wait_timeout: 120s
+  - query_timeout: 0 (disabled)
+- **Admin Console:** pgbouncer_admin user (password via PGBOUNCER_ADMIN_PASSWORD env var)
+- **Stats Console:** pgbouncer_stats user (password via PGBOUNCER_STATS_PASSWORD env var)
+
+**Migration Workaround:**
+- API has two DATABASE_URL env vars:
+  - `DATABASE_URL` → pgbouncer:6432 (normal queries)
+  - `DATABASE_URL_DIRECT` → postgres:5432 (migrations, introspection, DDL)
+- `RUN_MIGRATIONS=true` switches app to use DATABASE_URL_DIRECT for `prisma migrate deploy`
+
+#### Backup Strategy
+
+**Automated Backups:**
+- **Schedule:** Daily at 02:00 UTC (cron inside pg-backup container)
+- **Format:** Custom format with gzip compression (level 6)
+- **Retention:** 7 days (configurable via BACKUP_RETENTION_DAYS)
+- **Location:** `pg_backups` volume (mount to persistent storage in prod)
+- **File Pattern:** `goodgo_YYYYMMDD_HHMMSS.sql.gz`
+- **Restore Script:** `/scripts/backup/pg-restore.sh` (manual restore)
+- **Verification Script:** `/scripts/backup/pg-verify-backup.sh` (automated E2E verification)
+
+**Verification Process (runs weekly):**
+1. Restores latest backup to isolated test database (`goodgo_verify_<timestamp>`)
+2. Verifies all 22 tables exist
+3. Compares row counts between source and restored DB
+4. Checksums critical tables (User, Property, Listing, Payment, Subscription, Transaction, Plan, _prisma_migrations)
+5. Checks PostGIS extension, indexes, enum types
+6. Generates JSON report with pass/fail result
+7. **Cleanup:** Drops test DB on exit (unless SKIP_CLEANUP=1)
+8. **Exit Codes:** 0=pass, 1=checks failed, 2=setup error
+
+**CI/CD Backup Verification:**
+- GitHub Action: `.github/workflows/backup-verify.yml`
+- Runs weekly Sundays 05:00 UTC
+- Also manually triggerable with skip_cleanup option
+- Uploads JSON report as artifact

+## Caching & Search
+
+### Redis
+
+**Image:** `redis:7-alpine`  
+**Port:** 6379
+
+**Production Configuration:**
+```bash
+redis-server \
+  --appendonly yes \                # AOF persistence (updates only)
+  --requirepass ${REDIS_PASSWORD} \ # Authentication required
+  --maxmemory 512mb \               # Max memory limit (prod)
+  --maxmemory-policy allkeys-lru    # LRU eviction when full
+```
+
+**Development Configuration:**
+```bash
+redis-server \
+  --appendonly yes \
+  --maxmemory 256mb \
+  --maxmemory-policy allkeys-lru
+```
+
+**ioredis Client Configuration:**
+```typescript
+// From RedisService in apps/api/src/modules/shared/infrastructure/redis.service.ts
+{
+  host: process.env.REDIS_HOST ?? 'localhost',
+  port: Number(process.env.REDIS_PORT ?? 6379),
+  password: process.env.REDIS_PASSWORD ?? undefined,
+  lazyConnect: true,          // App starts even if Redis unavailable
+  enableReadyCheck: false,    // Prevents "Redis is not ready" errors during transient outages
+  maxRetriesPerRequest: 1,    // Fail fast (single retry, no exponential backoff)
+  retryStrategy(times: number): number {
+    return Math.min(times * 1000, 5000);  // 1s → 2s → 3s → 4s → 5s → 5s...
+  }
+}
+```
+
+**Graceful Degradation:**
+- Cache misses don't fail the application
+- CacheService catches Redis errors and returns cache miss
+- App serves data directly from PostgreSQL if Redis down
+- Health check at `GET /health/redis` warns but doesn't fail readiness probe
+
+**Use Cases:**
+- Session storage
+- Cache layer for expensive queries
+- Rate limiting (if implemented)
+- Real-time counters
+
+---
+
+### Typesense
+
+**Image:** `typesense/typesense:27.1`  
+**Port:** 8108 (HTTP only, internal Docker network)
+**API Key:** `${TYPESENSE_API_KEY}` (must be set in .env)
+
+**Collection Schema:**
+```
+Collection Name: "listings"
+Fields:
+  - listingId (string)
+  - propertyId (string)
+  - title (string, searchable, highlights)
+  - description (string, searchable, highlights)
+  - propertyType (string, faceted)
+  - transactionType (string, faceted: SALE/RENT)
+  - priceVND (int64, sortable)
+  - pricePerM2 (float, optional)
+  - areaM2 (float)
+  - bedrooms (int32, faceted)
+  - bathrooms (int32, faceted)
+  - floors (int32)
+  - direction (string, faceted: NORTH/SOUTH/EAST/WEST/etc)
+  - address (string)
+  - ward (string, faceted)
+  - district (string, faceted)
+  - city (string, faceted)
+  - location (geopoint) — for radius search
+  - agentId (string)
+  - sellerId (string)
+  - status (string, faceted: ACTIVE/SOLD/DRAFT/etc)
+  - publishedAt (int64, sortable)
+  - viewCount (int32)
+  - saveCount (int32)
+  - projectName (string, faceted)
+  - amenities (string[], faceted)
+```
+
+**Search Features:**
+- **Full-text search** on: title, description, address, district, city, projectName
+- **Query weights:** title=5, description=3, address=2, district=2, city=1, projectName=2
+- **Filtering:** propertyType, transactionType, bedrooms, district, city, status, amenities
+- **Geo-search:** radius-based queries (lat, lng, km)
+- **Sorting:** price (asc/desc), distance (asc from geopoint), date (desc), relevance
+- **Highlights:** HTML marks on matched terms in title and description
+- **Facets:** Return aggregated counts for filtering
+
+**TypesenseSearchRepository (`apps/api/src/modules/search/infrastructure/services/typesense-search.repository.ts`):**
+- `ensureCollection()` — Creates schema if not exists
+- `dropCollection()` — Cleanup (testing only)
+- `indexDocument(doc)` — Upsert single document
+- `indexDocuments(docs)` — Bulk import with error reporting
+- `removeDocument(id)` — Delete by ID
+- `search(params)` — Execute search with filters, sort, pagination
+
+**Graceful Degradation:**
+- If Typesense down, search falls back to PostgreSQL full-text search
+- TypesenseClientService implements retry logic with exponential backoff
+- Health check at `GET /health` returns JSON status

+
+### Loki & Promtail (Log Aggregation)
+
+**Loki:** `grafana/loki:3.0.0`, port 3100
+
+**Configuration:**
+```yaml
+schema:
+  - from: 2024-01-01
+    store: tsdb
+    schema: v13
+limits:
+  max_entries_limit_per_query: 5000

+
+## Payment Integration
+
+### Supported Payment Providers
+
+**Enum:** `PaymentProvider` (Prisma)
+- `VNPAY` — VNPay (Vietnam payment gateway)
+- `MOMO` — MoMo (Vietnam mobile wallet)
+- `ZALOPAY` — ZaloPay (Vietnam digital wallet)
+- `BANK_TRANSFER` — Manual bank transfer (offline)
+
+### Payment Flow & Callback Handling
+
+**Database Schema (Payment Model):**
+```typescript
+model Payment {
+  id            String @id @default(cuid())
+  userId        String
+  transactionId String?
+  provider      PaymentProvider
+  type          PaymentType  // SUBSCRIPTION, LISTING_FEE, DEPOSIT, FEATURED_LISTING
+  amountVND     BigInt
+  status        PaymentStatus  // PENDING, PROCESSING, COMPLETED, FAILED, REFUNDED
+  providerTxId  String?  // External transaction ID from VNPay/MoMo/ZaloPay
+  callbackData  Json?    // Raw callback payload (for audit)
+  idempotencyKey String? // Prevent duplicate payments (userId, provider, idempotencyKey unique)
+  createdAt     DateTime @default(now())
+  updatedAt     DateTime @updatedAt
+}
+
+enum PaymentStatus {
+  PENDING, PROCESSING, COMPLETED, FAILED, REFUNDED
+}
+
+enum PaymentType {
+  SUBSCRIPTION, LISTING_FEE, DEPOSIT, FEATURED_LISTING
+}
+```
+
+**Command Handler: `HandleCallbackHandler`**
+(`apps/api/src/modules/payments/application/commands/handle-callback/handle-callback.handler.ts`)
+
+1. **Callback Signature Verification:**
+   - Uses `PAYMENT_GATEWAY_FACTORY` to route to correct provider (VNPay/MoMo/ZaloPay)
+   - Gateway.verifyCallback() validates HMAC signature
+   - Throws `ValidationException` if signature invalid
+
+2. **Idempotent Status Transition:**
+   - Only updates payments in state: `PENDING` or `PROCESSING`
+   - Atomically transitions to `COMPLETED` or `FAILED`
+   - If already in terminal state (COMPLETED/FAILED/REFUNDED), returns existing status (idempotent)
+   - Logs warning if payment not found
+
+3. **Domain Event Publishing:**
+   - Reconstructs domain entity from repository
+   - Emits `PaymentCompletedEvent` or `PaymentFailedEvent`
+   - Event bus publishes events to subscribers (e.g., subscription creation, listing activation)
+
+4. **Response:**
+   ```typescript
+   {
+     paymentId: string,
+     status: PaymentStatus,
+     isSuccess: boolean
+   }
+   ```
+
+**Payment Gateway Interface (`payment-gateway.interface.ts`):**
+```typescript
+interface IPaymentGateway {
+  readonly provider: PaymentProvider
+  createPaymentUrl(params: CreatePaymentUrlParams): Promise<CreatePaymentUrlResult>
+  verifyCallback(data: Record<string, string>): CallbackVerifyResult
+  refund(params: RefundParams): Promise<RefundResult>
+}
+
+interface CreatePaymentUrlParams {
+  orderId: string
+  amountVND: bigint
+  description: string
+  returnUrl: string
+  ipAddress: string
+}
+
+interface CallbackVerifyResult {
+  isValid: boolean
+  orderId: string
+  providerTxId: string
+  isSuccess: boolean
+  rawData: Record<string, unknown>
+}
+
+interface RefundParams {
+  providerTxId: string
+  amountVND: bigint
+  reason: string
+}
+
+interface RefundResult {
+  success: boolean
+  refundTxId: string | null
+}
+```
+

+ZALOPAY_ENDPOINT=https://sb-openapi.zalopay.vn/v2
+```
+
+### Race Condition & Idempotency Protection
+
+**Problem:** Multiple callbacks may arrive for same payment (network retries, duplicate notifications)
+
+**Solution:**
+1. **Unique Idempotency Key:** `Payment_idempotency_unique(userId, provider, idempotencyKey)`
+   - Prevents duplicate payment records
+   - Generated by client/API before creating payment
+
+2. **Atomic Status Update:** `paymentRepo.updateIfStatus(orderId, ['PENDING', 'PROCESSING'], newStatus)`
+   - Only updates if current status in allowed list
+   - Returns updated entity or null if already terminal
+
+3. **Terminal State Check:** If already COMPLETED/FAILED/REFUNDED, handler returns existing state
+   - No re-triggering of domain events
+   - No double billing or duplicate transactions
+

+
+## Health Checks
+
+### API Health Endpoints
+
+**Health Controller** (`apps/api/src/modules/health/health.controller.ts`)
+
+1. **GET /health** — Liveness Probe (always 200 if process running)
+   - Uses: `@HealthCheck()` on empty probe list
+   - Response: `{ "status": "ok", "timestamp": "..." }`
+   - **Use Case:** Kubernetes/Docker readiness (initial startup)
+
+2. **GET /health/ready** — Readiness Probe (checks dependencies)
+   - Checks: PostgreSQL + Redis connectivity
+   - Response:
+     ```json
+     {
+       "status": "ok",
+       "checks": {
+         "database": { "status": "up" },
+         "redis": { "status": "up" }
+       }
+     }
+     ```
+   - **Use Case:** Load balancer, before accepting traffic
+   - **Failure:** Returns 503 if any dependency down
+
+3. **GET /health/db** — Database Readiness Only
+   - Checks: PostgreSQL connectivity via `SELECT 1` query
+   - **Use Case:** Manual database troubleshooting
+
+4. **GET /health/redis** — Redis Readiness Only
+   - Checks: Redis PING command
+   - **Use Case:** Manual Redis troubleshooting
+
+### Health Check Implementations
+
+**PrismaHealthIndicator** (`apps/api/src/modules/health/infrastructure/prisma.health.ts`):
+```typescript
+async isHealthy(key: string): Promise<HealthIndicatorResult> {
+  try {
+    await this.prisma.$queryRawUnsafe('SELECT 1');
+    return this.getStatus(key, true);
+  } catch {

+    const pong = await client.ping();
+    const isHealthy = pong === 'PONG';
+    const result = this.getStatus(key, isHealthy);
+    if (isHealthy) return result;
+    throw new HealthCheckError('Redis ping failed', result);
+  } catch (error) {
+    if (error instanceof HealthCheckError) throw error;
+    throw new HealthCheckError('Redis check failed', this.getStatus(key, false));
+  }
+}
+```

+
+## Backup & Recovery
+
+### Automated Daily Backups
+
+**Service:** `pg-backup` container (runs inside docker compose)
+
+**Backup Script:** `scripts/backup/pg-backup.sh`
+
+```bash
+# Daily cron job: 02:00 UTC
+PGHOST=postgres \
+PGPORT=5432 \
+PGUSER=goodgo \
+PGDATABASE=goodgo \
+PGPASSWORD=<secret> \
+BACKUP_DIR=/backups \
+RETENTION_DAYS=7 \
+  /scripts/pg-backup.sh
+```
+
+**Behavior:**
+1. Creates dump with `pg_dump --format=custom --compress=6`
+2. Saves as `goodgo_YYYYMMDD_HHMMSS.sql.gz`
+3. Prunes backups older than 7 days (configurable)
+4. Logs to `/var/log/pg-backup.log`
+
+**Restore from Backup:**
+
+```bash
+# Interactive restore prompt
+docker compose -f docker-compose.prod.yml exec pg-backup bash -c \
+  'pg_restore -h postgres -p 5432 -U goodgo -d goodgo \
+   --clean --if-exists /backups/goodgo_20260410_020000.sql.gz'
+
+# Or using restore script
+docker compose -f docker-compose.prod.yml run --rm pg-verify-backup bash -c \
+  'source /scripts/pg-restore.sh /backups/goodgo_20260410_020000.sql.gz'
+```
+
+### Backup Verification
+
+**Service:** `pg-verify-backup` container (on-demand, profile: tools)
+
+**Verification Script:** `scripts/backup/pg-verify-backup.sh`
+
+```bash
+# Usage:
+docker compose -f docker-compose.prod.yml run --rm pg-verify-backup
+
+# Or with options:
+SKIP_CLEANUP=1 REPORT_FILE=/backups/verify-report.json \
+  docker compose -f docker-compose.prod.yml run --rm pg-verify-backup
+```
+
+**Verification Steps:**
+1. Creates isolated test database: `goodgo_verify_<timestamp>`
+2. Enables PostGIS extension
+3. Restores backup into test DB
+4. Verifies all 22 tables exist
+5. Compares row counts between source and restored
+6. Checksums critical tables using MD5 hashes
+7. Checks indexes, enum types
+8. Generates JSON report with results
+9. **Cleanup:** Drops test DB (unless SKIP_CLEANUP=1)
+
+**JSON Report Structure:**
+```json
+{
+  "timestamp": "2026-04-11T10:30:00Z",
+  "backupFile": "/backups/goodgo_20260410_020000.sql.gz",
+  "backupSize": "150M",
+  "testDatabase": "goodgo_verify_20260411_103000",

+    { "check": "Checksum: User identities", "status": "pass", "detail": "Hashes match (abc123def456...)" },
+    ...
+  ]
+}
+```
+
+**GitHub Action Backup Verification:**
+- File: `.github/workflows/backup-verify.yml`
+- Schedule: Weekly Sundays 05:00 UTC
+- Also: Manual trigger with skip_cleanup option
+- Artifacts: Uploads JSON report for 30 days
+
+---
+
+## Deployment Pipeline
+
+### GitHub Actions CI/CD
+
+**Workflows:**
+1. `.github/workflows/ci.yml` — Lint, typecheck, test, build (on push/PR to master)
+2. `.github/workflows/deploy.yml` — Build Docker images, deploy to staging/prod
+3. `.github/workflows/e2e.yml` — E2E tests (spins up full docker-compose.ci.yml)
+4. `.github/workflows/backup-verify.yml` — Weekly backup verification
+5. `.github/workflows/security.yml` — Dependency scanning, SAST
+6. `.github/workflows/codeql.yml` — GitHub CodeQL analysis
+7. `.github/workflows/load-test.yml` — K6 load testing
+
+### CI Pipeline (`ci.yml`)
+
+**On:** `push master`, `pull_request master`  
+**Node:** 22  
+**Concurrency:** Cancel previous runs on same ref
+
+**Jobs:**
+1. **Lint → Typecheck → Test → Build**
+   - Installs pnpm, Node 22
+   - Runs linter (eslint)
+   - Type checks (tsc)
+   - Unit tests (jest)
+   - Builds all apps (turbo)
+   - PostgreSQL 16 service available (goodgo_test DB)
+
+2. **E2E Tests** (depends on ci job)
+   - Full docker-compose.ci.yml services (postgres, redis, typesense, minio)
+   - Runs end-to-end test suite
+   - Timeout: 20 minutes
+   - Env vars: DATABASE_URL, JWT secrets, payment test codes
+
+### Deploy Pipeline (`deploy.yml`)
+
+**On:** 
+- `push master` (auto-deploys to staging)
+- Manual `workflow_dispatch` (choose staging or production)
+
+**Jobs:**
+1. **Build API Image**
+   - Builds: `goodgo-api:${IMAGE_TAG}`
+   - Dockerfile: `apps/api/Dockerfile`
+   - Registry: `ghcr.io/goodgo/goodgo-api`
+   - Tags: git SHA, branch name, `latest` (on master)
+
+2. **Build Web Image**
+   - Builds: `goodgo-web:${IMAGE_TAG}`
+   - Dockerfile: `apps/web/Dockerfile`
+   - Registry: `ghcr.io/goodgo/goodgo-web`
+
+3. **Build AI Services Image**
+   - Builds: `goodgo-ai-services:${IMAGE_TAG}`
+   - Context: `libs/ai-services/`
+   - Registry: `ghcr.io/goodgo/goodgo-ai-services`
+
+4. **Deploy to Staging**
+   - Condition: `github.event_name == 'push' || inputs.environment == 'staging'`
+   - SSH into staging host
+   - Pulls new images from GHCR
+   - **Rolling update** (zero downtime):
+     ```bash
+     docker compose -f docker-compose.prod.yml up -d --no-deps --wait api
+     docker compose -f docker-compose.prod.yml up -d --no-deps --wait web
+     docker compose -f docker-compose.prod.yml up -d --no-deps --wait ai-services
+     ```
+   - Runs migrations: `docker compose exec api npx prisma migrate deploy`
+   - Prunes old images
+
+5. **Deploy to Production**
+   - Only on manual `workflow_dispatch` with `environment: production`
+   - Same steps as staging
+   - Requires `environment: production` approval (GitHub security)
+
+### Dockerfile Multi-Stage Builds
+
+**API (apps/api/Dockerfile):**
+- **Base:** node:22-slim + pnpm 10.27.0
+- **Deps:** Install locked dependencies (layer caching)
+- **Build:** Compile TypeScript, generate Prisma client
+- **Prune:** `pnpm deploy --prod` (removes dev deps, hoists prod deps)
+- **Production:** Minimal image, dumb-init for signals, non-root user
+
+**Web (apps/web/Dockerfile):**
+- **Base:** node:22-slim + pnpm
+- **Deps:** Install dependencies
+- **Build:** `next build` → standalone output + static files
+- **Production:** Copy .next/standalone, public, static assets
+
+**AI Services (libs/ai-services/Dockerfile):**
+- **Base:** python:3.12-slim
+- **Install:** System deps (gcc, g++), dumb-init, FastAPI/XGBoost/underthesea
+- **Models:** Pre-download underthesea ML models at build time
+- **User:** Run as non-root appuser
+- **CMD:** `uvicorn app.main:app --host 0.0.0.0 --port 8000`

+
+## Troubleshooting Guide
+
+### Check Service Status
+
+```bash
+# All services
+docker compose -f docker-compose.prod.yml ps
+
+# Single service
+docker compose -f docker-compose.prod.yml ps api
+
+# Get logs
+docker compose -f docker-compose.prod.yml logs -f api --tail=100
+
+# Health check status
+docker compose -f docker-compose.prod.yml exec api curl http://localhost:3001/health
+```
+
+### Common Issues
+
+#### 1. API Service Not Healthy (stuck in "health-check-failed" state)
+
+**Symptoms:**
+- `docker compose ps` shows `(health: starting)` for >2 minutes
+- `docker compose logs api` shows connection errors
+
+**Diagnosis:**
+```bash
+# Check API liveness
+docker compose exec api curl http://localhost:3001/health
+
+# Check readiness (includes DB + Redis checks)
+docker compose exec api curl http://localhost:3001/health/ready
+
+# Check specific dependencies
+docker compose exec api curl http://localhost:3001/health/db
+docker compose exec api curl http://localhost:3001/health/redis
+```
+
+**Solutions:**
+
+- **PostgreSQL not ready:**
+  ```bash
+  docker compose ps postgres  # Should show (healthy)
+  docker compose exec postgres pg_isready -U goodgo -d goodgo
+  docker compose logs postgres --tail=50
+  ```
+
+- **Redis not ready:**
+  ```bash
+  docker compose exec redis redis-cli ping  # Should return PONG
+  docker compose logs redis --tail=50
+  ```
+
+- **PgBouncer not ready (prod):**
+  ```bash
+  docker compose exec pgbouncer pg_isready -h 127.0.0.1 -p 6432 -U goodgo
+  docker compose logs pgbouncer --tail=50
+  ```
+
+- **Database schema not initialized:**
+  ```bash
+  # Run migrations manually
+  docker compose exec api npx prisma migrate deploy
+  # Or check if schema exists
+  docker compose exec postgres psql -U goodgo -d goodgo -c "\dt"
+  ```
+
+#### 2. High Database Connection Pool Exhaustion
+
+**Symptoms:**
+- Errors: `Error: unable to get a connection from the pool after X s`
+- Slow queries pile up
+- API latency spikes
+
+**Diagnosis:**
+```bash
+# Check pool stats (prod, PgBouncer)
+docker compose exec pgbouncer psql -h 127.0.0.1 -p 6432 -U pgbouncer_stats -c "SHOW stats"
+
+# Or query PostgreSQL directly
+docker compose exec postgres psql -U goodgo -d goodgo -c "SELECT count(*) FROM pg_stat_activity"
+```
+
+**Solutions:**
+- Increase `PGBOUNCER_POOL_SIZE` (default: 20)
+- Increase `PGBOUNCER_MAX_CLIENT_CONN` (default: 200)
+- Reduce long-running queries (add query timeout)
+- Check for idle connections: `server_idle_timeout`
+
+#### 3. Redis Connection Failures (Non-Fatal)
+
+**Symptoms:**
+- Logs: `Redis check failed` or `ECONNREFUSED`
+- But API still responds with slower database reads
+- Health check `/health/ready` returns 503
+
+**Expected Behavior:** Cache misses → app serves from database
+
+**Diagnosis:**
+```bash
+# Check Redis availability
+docker compose exec redis redis-cli ping
+
+# Check RedisService logs
+docker compose logs api | grep -i redis
+```
+
+**Solutions:**
+- Restart Redis: `docker compose restart redis`
+- Check memory: `docker compose exec redis redis-cli info memory`
+- If at `maxmemory`, increase in docker-compose.yml and restart
+
+#### 4. Typesense Search Not Indexing
+
+**Symptoms:**
+- Search returns 0 results
+- Listings created but not searchable
+- `/health` for typesense shows green, but collection empty
+
+**Diagnosis:**
+```bash
+# Check collection exists
+curl http://localhost:8108/collections -H "X-TYPESENSE-API-KEY: ${TYPESENSE_API_KEY}"
+
+# Check collection stats
+curl "http://localhost:8108/collections/listings" \
+  -H "X-TYPESENSE-API-KEY: ${TYPESENSE_API_KEY}" | jq .
+
+# Check recent docs
+curl "http://localhost:8108/collections/listings/documents/search?q=*" \
+  -H "X-TYPESENSE-API-KEY: ${TYPESENSE_API_KEY}" | jq '.found'
+```
+
+**Solutions:**
+- Verify `TYPESENSE_API_KEY` matches container env var
+- Reindex all listings:
+  ```bash
+  docker compose exec api npx ts-node scripts/reindex-listings.ts
+  ```
+- If collection corrupted, drop and recreate:
+  ```bash
+  curl -X DELETE "http://localhost:8108/collections/listings" \
+    -H "X-TYPESENSE-API-KEY: ${TYPESENSE_API_KEY}"
+  # Then restart API service to recreate schema
+  docker compose restart api
+  ```
+
+#### 5. Payment Callback Failures
+
+**Symptoms:**
+- Payment status stuck in `PENDING`
+- Logs: `Invalid callback signature for provider=VNPAY`
+
+**Diagnosis:**
+```bash
+# Check payment record in DB
+docker compose exec postgres psql -U goodgo -d goodgo -c \
+  "SELECT id, status, provider, \"providerTxId\", \"callbackData\" FROM \"Payment\" \
+   WHERE \"providerTxId\" = 'your-txid' ORDER BY \"createdAt\" DESC LIMIT 1;"
+
+# Check logs for callback handler
+docker compose logs api | grep -i "HandleCallbackHandler\|callback"
+```
+
+**Solutions:**
+- Verify payment gateway credentials (VNPAY_HASH_SECRET, MOMO_SECRET_KEY, etc.)
+- Manually verify callback signature (contact payment provider support)
+- Replay callback manually (if idempotent key available):
+  ```bash
+  curl -X POST http://localhost:3001/api/payments/callback \
+    -H "Content-Type: application/json" \
+    -d '{"provider":"VNPAY",...callback data...}'
+  ```
+
+#### 6. Backup Verification Fails
+
+**Symptoms:**
+- GitHub Action `.github/workflows/backup-verify.yml` fails
+- Restore test database shows mismatched row counts
+
+**Diagnosis:**
+```bash
+# Run verification manually
+docker compose -f docker-compose.ci.yml up postgres
+docker compose -f docker-compose.ci.yml exec postgres \
+  /scripts/pg-verify-backup.sh /backups/goodgo_latest.sql.gz
+
+# Check JSON report
+cat /tmp/backups/verify-report.json | jq .
+```
+
+**Solutions:**
+- Check if backup file corrupt: `file goodgo_*.sql.gz`
+- Verify restore process: `pg_restore --verbose`
+- Check PostGIS extension availability: `psql -c "CREATE EXTENSION postgis;"`
+
+#### 7. Memory/CPU Pressure
+
+**Symptoms:**
+- OOM kills, container exits 137
+- CPU throttling, latency spikes
+- Prometheus `container_memory_usage_bytes` near limit
+
+**Diagnosis:**
+```bash
+# Check Docker stats
+docker stats --no-stream
+
+# Check limits in compose file
+docker compose config | grep -A3 "resources:"
+
+# Check actual memory usage
+docker inspect goodgo-api | jq '.HostConfig.Memory'
+```
+
+**Solutions:**
+- Increase resource limits in `docker-compose.prod.yml`
+- Reduce log verbosity (set LOG_LEVEL=warn)
+- Implement pagination for large queries
+- Scale horizontally (add more API replicas)
+
+### Prometheus Queries for Debugging
+
+```promql
+# API request latency p99
+histogram_quantile(0.99, sum(rate(goodgo_api_request_duration_seconds_bucket[5m])) by (le))
+
+# API error rate (5xx)
+(sum(rate(http_requests_total{status_code=~"5.."}[5m])) / sum(rate(http_requests_total[5m]))) * 100
+
+# Container memory usage
+container_memory_usage_bytes{name="goodgo-api"}
+
+# Container CPU usage
+rate(container_cpu_usage_seconds_total{name="goodgo-api"}[5m])
+
+# PostgreSQL active queries
+pg_stat_activity_count{state="active"}
+
+# Redis memory usage
+redis_memory_used_bytes / 1024 / 1024  # in MB
+
+# Typesense collection size
+typesense_documents_count{collection="listings"}
+```
+
+### Emergency Procedures
+
+**Full System Reset (dev only):**
+```bash
+docker compose down -v  # Remove all volumes!
+docker system prune -a
+docker compose up -d --wait
+docker compose exec api npx prisma db push
+docker compose exec api npx ts-node scripts/seed.ts
+```
+
+**Database Emergency Restore:**
+```bash
+# Find latest backup
+ls -t /var/lib/docker/volumes/pg_backups/_data/goodgo_*.sql.gz | head -1
+
+# Restore to new database
+pg_restore -h localhost -p 5432 -U goodgo -d goodgo_restored \
+  --clean --if-exists --verbose /path/to/backup.sql.gz
+
+# Verify restore
+psql -U goodgo -d goodgo_restored -c "SELECT count(*) FROM \"User\";"
+```
+
+**Force Kill Stuck Service:**
+```bash
+# If health check broken
+docker compose kill api
+docker compose rm -f api
+docker compose up -d api
+```

+
+### **Data Flow**
+
+**Creating Inquiry:**
+```
+POST /inquiries (CreateInquiryDto)
+  → InquiriesController.createInquiry()
+  → CommandBus.execute(CreateInquiryCommand)
+  → CreateInquiryHandler.execute()
+    - Validate listing exists (Prisma)
+    - Create InquiryEntity
+    - Save to repository (Prisma)
+    - Publish InquiryCreatedEvent via EventBus
+  → Return { id, listingId, createdAt }
+```
+
+**Marking as Read:**
+```
+PATCH /inquiries/:id/read (agent only)
+  → InquiriesController.markAsRead()
+  → CommandBus.execute(MarkInquiryReadCommand)
+  → MarkInquiryReadHandler.execute()
+    - Find inquiry entity
+    - Verify agent is listing owner
+    - Call entity.markAsRead()
+    - Update in repository
+    - Publish InquiryReadEvent via EventBus
+  → Return { success: true }
+```
+
+**Getting Inquiries:**
+```
+GET /inquiries/listing/:id or /agent/me (with pagination)
+  → InquiriesController.getByListing() or getMyInquiries()
+  → QueryBus.execute(GetInquiriesByListingQuery or GetInquiriesByAgentQuery)
+  → Handler delegates to repository
+  → Repository.findByListing() or findByAgent()
+    - Queries Prisma with joins
+    - Maps to InquiryReadDto
+    - Returns PaginatedResult
+  → Return paginated data
+```
+

+
+## 🔑 KEY CLASSES & HANDLERS
+
+### **Domain Entity: InquiryEntity**
+
+```typescript
+export class InquiryEntity extends AggregateRoot<string> {
+  // Properties
+  private _listingId: string;
+  private _userId: string;
+  private _message: string;
+  private _phone: string | null;
+  private _isRead: boolean;
+
+  // Factory Method
+  static createNew(id, listingId, userId, message, phone): InquiryEntity
+    → Creates new inquiry with isRead=false
+    → Emits InquiryCreatedEvent
+
+  // Business Logic
+  markAsRead(): void
+    → Sets isRead to true
+    → Emits InquiryReadEvent
+}
+```
+
+### **Command Handlers**
+
+#### CreateInquiryHandler
+```typescript
+class CreateInquiryHandler implements ICommandHandler<CreateInquiryCommand> {
+  async execute(command: CreateInquiryCommand): Promise<CreateInquiryResult> {
+    // 1. Validate listing exists
+    const listing = await prisma.listing.findUnique(...)
+    if (!listing) throw NotFoundException
+
+    // 2. Create entity with factory
+    const inquiry = InquiryEntity.createNew(...)
+
+    // 3. Persist to database
+    await inquiryRepo.save(inquiry)
+
+    // 4. Publish domain events
+    const events = inquiry.clearDomainEvents()
+    events.forEach(e => eventBus.publish(e))
+
+    return { id, listingId, createdAt }
+  }
+}
+```
+
+#### MarkInquiryReadHandler
+```typescript
+class MarkInquiryReadHandler implements ICommandHandler<MarkInquiryReadCommand> {
+  async execute(command: MarkInquiryReadCommand): Promise<void> {
+    // 1. Load aggregate root
+    const inquiry = await inquiryRepo.findById(...)
+    if (!inquiry) throw NotFoundException
+
+    // 2. Verify authorization
+    const listing = await prisma.listing.findUnique(...)
+    const agent = await prisma.agent.findUnique(...)
+    if (agent.id !== listing.agentId) throw ForbiddenException
+
+    // 3. Update domain state
+    inquiry.markAsRead()
+
+    // 4. Persist state
+    await inquiryRepo.markAsRead(...)
+
+    // 5. Publish events
+    const events = inquiry.clearDomainEvents()
+    events.forEach(e => eventBus.publish(e))
+  }
+}
+```
+
+### **Query Handlers**
+
+#### GetInquiriesByListingHandler
+```typescript
+class GetInquiriesByListingHandler implements IQueryHandler<GetInquiriesByListingQuery> {
+  async execute(query: GetInquiriesByListingQuery): Promise<PaginatedResult<InquiryReadDto>> {
+    return this.inquiryRepo.findByListing(
+      query.listingId,
+      query.page,
+      query.limit
+    )
+  }
+}
+```
+
+#### GetInquiriesByAgentHandler
+```typescript
+class GetInquiriesByAgentHandler implements IQueryHandler<GetInquiriesByAgentQuery> {
+  async execute(query: GetInquiriesByAgentQuery): Promise<PaginatedResult<InquiryReadDto>> {
+    // 1. Resolve agent ID from user ID
+    const agent = await prisma.agent.findUnique({ where: { userId } })
+    if (!agent) throw NotFoundException
+
+    // 2. Delegate to repository
+    return this.inquiryRepo.findByAgent(agent.id, page, limit)
+  }
+}
+```
+
+### **Repository Implementation**
+
+#### PrismaInquiryRepository
+
+**Methods:**
+1. `findById(id)` - Single inquiry lookup
+2. `save(entity)` - Create inquiry
+3. `markAsRead(id)` - Update isRead flag
+4. `findByListing(listingId, page, limit)` - Paginated search with joins
+5. `findByAgent(agentId, page, limit)` - Paginated search via listing agent
+6. `countUnreadByAgent(agentId)` - Unread count aggregation
+
+**Prisma Relations Used:**
+- `inquiry.listing` → property (for title)
+- `inquiry.user` → fullName, phone
+- `listing.agentId` → agent filter
+- Pagination: skip/take with orderBy descending
+

+## 🎓 ARCHITECTURAL INSIGHTS
+
+### **Strengths**
+
+1. **Clean Architecture** - Clear separation of concerns across layers
+2. **CQRS Pattern** - Separate read/write paths enable scalability
+3. **Domain-Driven Design** - Business logic in entities, not anemic models
+4. **Event-Driven** - Domain events enable audit trails and event sourcing
+5. **Testability** - Each layer independently testable with mocks
+6. **Type Safety** - Full TypeScript with interfaces and strict types
+7. **DI Framework** - NestJS provides dependency injection out of box
+
+### **Design Decisions**
+
+1. **InquiryEntity as Aggregate Root**
+   - Encapsulates inquiry business rules
+   - Controls state transitions via methods (createNew, markAsRead)
+   - Collects domain events
+
+2. **Repository Pattern**
+   - Interface in domain, implementation in infrastructure
+   - Allows swapping data sources without affecting business logic
+
+3. **Separate Read/Write DTOs**
+   - `CreateInquiryDto` (input) vs `InquiryReadDto` (output)
+   - Enables flexible API evolution
+
+4. **CQRS Handlers**
+   - Commands handle mutations with authorization
+   - Queries handle reads with filtering
+   - Both independent, can be optimized separately
+
+5. **Pagination Interface**
+   - Consistent pagination across all list endpoints
+   - Page + limit model with calculated totalPages

+// Domain interface (repository contract)
+interface IInquiryRepository {
+  findById(id: string): Promise<InquiryEntity | null>
+  save(inquiry: InquiryEntity): Promise<void>
+  markAsRead(id: string): Promise<void>

+
+## 🧪 TEST FILES AT A GLANCE
+
+| Test File | Tests | Focus |
+|-----------|-------|-------|
+| `domain/__tests__/inquiry-domain.spec.ts` | 5 | Entity creation, events |
+| `application/__tests__/create-inquiry.handler.spec.ts` | 4 | Handler success, validation |
+| `application/__tests__/mark-inquiry-read.handler.spec.ts` | 5 | Handler success, auth checks |
+| `application/__tests__/get-inquiries-by-listing.handler.spec.ts` | 2 | Query results, empty state |
+| `application/__tests__/get-inquiries-by-agent.handler.spec.ts` | 2 | Query results, agent lookup |
+| `presentation/__tests__/inquiries.controller.spec.ts` | 6 | All endpoints, defaults |
+| **TOTAL** | **24** | **Comprehensive coverage** |
+
+---
+
+## 🔐 Authorization Matrix
+
+| Endpoint | Auth | Role | Query |
+|----------|------|------|-------|
+| `POST /inquiries` | JWT | Any | - |
+| `GET /listing/:id` | JWT | Any | page, limit |
+| `GET /agent/me` | JWT | AGENT | page, limit |
+| `PATCH /:id/read` | JWT | AGENT | - |
+
+**Permission Checks:**
+- MarkInquiryReadHandler: Verifies user is agent, agent owns listing
+
+---
+
+## 🎯 DDD PRINCIPLES
+
+### Domain Entity Encapsulation
+```typescript
+// Factory method (controlled creation)
+static createNew(id, listingId, userId, message, phone): InquiryEntity
+  → Creates entity with isRead=false
+  → Emits InquiryCreatedEvent
+
+// Domain methods (state transitions)
+markAsRead(): void
+  → Sets isRead=true
+  → Emits InquiryReadEvent
+```
+
+### Repository Pattern
+- **Interface in Domain** → `IInquiryRepository`
+- **Implementation in Infrastructure** → `PrismaInquiryRepository`
+- **Dependency Injection** → `INQUIRY_REPOSITORY` symbol
+
+### Separate Read/Write Models
+- **Write Model:** `InquiryEntity` (aggregate)
+- **Read Model:** `InquiryReadDto` (query DTO)
+
+---
+
+## 🔄 Domain Events
+
+| Event | When | Data |
+|-------|------|------|
+| **InquiryCreatedEvent** | Inquiry created | aggregateId, listingId, userId |
+| **InquiryReadEvent** | Marked as read | aggregateId, listingId, userId |
+
+---
+
+## 💾 Database Operations
+
+**Prisma Models Used:**
+- `inquiry` - Main entity
+- `listing` - For foreign key & agent lookup
+- `property` - For listing title
+- `user` - For buyer name & phone
+
+**Key Queries:**
+- `inquiry.create()` - New inquiry
+- `inquiry.update()` - Mark read
+- `inquiry.findMany()` - Pagination
+- `inquiry.count()` - Total count
+
+---
+
+## 🚀 Entry Points
+
+```typescript
+// Module export
+export { InquiriesModule }
+
+// Exported interfaces
+export { INQUIRY_REPOSITORY, type IInquiryRepository }
+export { InquiryEntity }
+
+// Usage in other modules
+import { InquiriesModule } from '@modules/inquiries'
+```
+
+---
+
+## 🎓 Architecture Summary
+
+```
+CLEAN ARCHITECTURE with CQRS + DDD
+
+Presentation Layer (Controllers + DTOs)
+         ↓
+Application Layer (CQRS Handlers)
+         ↓
+Domain Layer (Entities + Events + Interfaces)
+         ↓
+Infrastructure Layer (Prisma Repository)
+         ↓
+Database
+```
+
+**Key Characteristics:**
+✅ Dependency Inversion - Domain defines contracts  
+✅ Separation of Concerns - Each layer has clear responsibility  
+✅ Testability - Mock implementations at each layer  
+✅ Event-Driven - Domain events for audit & integration  
+✅ CQRS - Separate commands & queries for scalability  
+✅ Type Safety - Full TypeScript with strict interfaces  
+
+---
+
+## 📌 Common Patterns
+
+**Command Pattern:**
+```typescript
+// Send command
+commandBus.execute(new CreateInquiryCommand(...))
+// Handler processes
+@CommandHandler(CreateInquiryCommand)
+class CreateInquiryHandler { ... }
+```
+
+**Query Pattern:**
+```typescript
+// Send query
+queryBus.execute(new GetInquiriesByListingQuery(...))
+// Handler processes
+@QueryHandler(GetInquiriesByListingQuery)
+class GetInquiriesByListingHandler { ... }
+```
+
+**Dependency Injection Pattern:**
+```typescript
+@Injectable()
+export class Handler {
+  constructor(
+    @Inject(INQUIRY_REPOSITORY) private repo: IInquiryRepository,
+    private prisma: PrismaService,
+  ) {}
+}
+```
+
+---
+
+## 🔍 Where to Look For...
+
+| Need | File |
+|------|------|
+| Add new endpoint | `presentation/controllers/inquiries.controller.ts` |
+| Add command | `application/commands/[name]/[name].command.ts` + `[name].handler.ts` |
+| Add query | `application/queries/[name]/[name].query.ts` + `[name].handler.ts` |
+| Business logic | `domain/entities/inquiry.entity.ts` |
+| New domain event | `domain/events/[name].event.ts` |
+| Database queries | `infrastructure/repositories/prisma-inquiry.repository.ts` |
+| Input validation | `presentation/dto/*.ts` |
+| Write tests | `[layer]/__tests__/*` |

+
+## 📈 Component Complexity Levels
+
+### Level 1: Simple UI Components
+```
+Badge, Button, Input, Label
+├─ Props: basic props + variants
+├─ State: none
+└─ Interactions: click, focus, hover
+```
+
+### Level 2: Composite Components
+```
+Card (Header + Content + Footer)
+ImageUpload (Drag-drop + Preview grid)
+├─ Props: content children
+├─ State: local state
+└─ Interactions: click, drag, input
+```
+
+### Level 3: Feature Components
+```
+ImageGallery (Main + Thumbnails)
+PropertyCard (Link + Image + Info)
+├─ Props: data + callbacks
+├─ State: selected index, UI state
+└─ Interactions: navigation, filtering
+```
+
+### Level 4: Page Components
+```
+ListingDetailClient (Full page layout)
+├─ Props: listing data
+├─ State: multiple features
+├─ Interactions: all user interactions
+└─ Children: multiple feature components
+```
+
+---
+
+## 🚀 Performance Considerations
+
+### Image Optimization
+
+```
+Image Component Strategy:
+├─ Next.js Image component
+│  ├─ Automatic format selection (WebP, AVIF)
+│  ├─ Responsive serving via srcset
+│  └─ On-demand resizing
+│
+├─ Lazy Loading
+│  ├─ Main image: priority={selectedIndex === 0}
+│  └─ Thumbnails: no priority (lazy)
+│
+└─ Responsive Sizing
+   ├─ sizes prop: tells browser image dimensions
+   └─ Prevents layout shift
+```
+
+### Code Splitting
+
+```
+Dynamic Imports:
+├─ ListingMap (heavy, maps library)
+│  ├─ ssr: false (client-only)
+│  └─ loading: placeholder component
+│
+└─ Other components: bundled with page
+```
+
+### State Optimization
+
+```
+Zustand:
+├─ Selector pattern: useStore(state => state.field)
+├─ Only re-render on selected state change
+└─ Persist middleware: localStorage only on needed data
+```
+
+---
+
+## 🔄 Navigation Flow
+
+### User Journey - Image Gallery
+
+```
+1. User visits /vi/listings/123
+   └─ Page loads with first image (priority=true)
+   
+2. User interacts with gallery:
+   ├─ Click thumbnail
+   │  └─ setSelectedIndex(index) → main image updates
+   │
+   ├─ Click next button
+   │  └─ setSelectedIndex(i + 1) → wraps to 0
+   │
+   └─ Click prev button
+      └─ setSelectedIndex(i - 1) → wraps to last
+```
+
+### User Journey - File Upload (Create/Edit Listing)
+
+```
+1. User opens listing form
+   └─ ImageUpload component mounts
+
+2. User adds images:
+   ├─ Drag & drop files
+   │  └─ addFiles() → filter + validate → onChange()
+   │
+   └─ Click to browse
+      └─ Select files → same as drag & drop
+
+3. User removes image:
+   └─ removeImage(index) → cleanup URL → onChange()
+
+4. User submits form:
+   └─ Images uploaded via listingsApi.uploadMedia()
+```

+
+## 💡 Tips & Best Practices
+
+### Image Optimization
+- Always use `sizes` prop with Next.js Image
+- Set `priority={true}` only for above-fold images
+- Use aspect ratio containers to prevent layout shift
+- Let Next.js handle format selection (WebP, AVIF)
+
+### Component Design
+- Keep components focused (single responsibility)
+- Use CVA for variant management
+- Use composition over inheritance
+- Keep local state for UI, global for app state
+
+### State Management
+- Use Zustand for global state (auth, comparison)
+- Use local React state for component UI (gallery index)
+- Use React Query for server state
+- Persist only essential data to localStorage
+
+### Testing
+- Mock Next.js Image component
+- Test responsive behavior
+- Test edge cases (empty state, many images)
+- Mock Zustand stores
+

+
+## 1. Property Detail Page Structure
+
+### File Location
+```
+apps/web/app/[locale]/(public)/listings/[id]/
+├── page.tsx          # Server component - fetches data, generates metadata, JSON-LD
+└── (referenced) listing-detail-client.tsx  # Client component - handles interactivity
+```
+
+### Page Architecture
+**Server Component** (`page.tsx`):
+- Fetches listing data via `fetchListingById(params.id)`
+- Generates SEO metadata (Open Graph, Twitter Cards, canonical URLs)
+- Generates JSON-LD structured data (breadcrumbs, property schema)
+- Renders structured data and passes data to client component
+
+**Client Component** (`listing-detail-client.tsx`):
+- All interactivity (image gallery state, forms, etc.)
+- Uses dynamic imports for heavy components (ListingMap)
+- Main sections:
+  - Breadcrumb navigation
+  - Header with title, price, badges
+  - **Image Gallery** (main content area)
+  - Quick stats bar (area, bedrooms, bathrooms, floors, direction)
+  - Two-column layout:
+    - Left (2/3): Description, Details, Amenities, Map, Contact Card
+    - Right (1/3): Sticky sidebar with contact info, AI Estimate, Stats
+
+### Data Flow
+```
+page.tsx (Server)
+  └─> fetchListingById() ─> ListingDetail object
+  └─> generateMetadata() ─> SEO metadata
+  └─> ListingDetailClient (Client)
+      └─> ImageGallery component
+      └─> AddToCompareButton component
+      └─> AiEstimateButton component
+      └─> dynamic ListingMap component
+```

+
+## 2. Property Images - Current Implementation
+
+### Image Gallery Component
+**File**: `apps/web/components/listings/image-gallery.tsx`
+
+#### Features:
+- **Main Display**:
+  - Aspect ratio: 16:9 (aspect-video)
+  - Uses Next.js `Image` component with `fill` layout
+  - Object fit: cover
+  - Rounded corners
+  - Previous/Next navigation buttons (semi-transparent overlay, hover effects)
+  - Current image counter (bottom-right: "X / Total")
+
+- **Thumbnail Navigation**:

+## 4. Project Component Structure & Patterns
+
+### Design System Approach
+- **UI Components**: Located in `components/ui/`
+- **Pattern**: CVA (class-variance-authority) for variants
+- **Example** (button.tsx):
+  ```typescript
+  const buttonVariants = cva(
+    'inline-flex items-center justify-center ...',
+    {
+      variants: {
+        variant: { default: '...', outline: '...', ghost: '...', ... },
+        size: { default: '...', sm: '...', lg: '...', icon: '...' },
+      },
+      defaultVariants: { variant: 'default', size: 'default' },
+    }
+  );
+  ```
+
+### Composition Pattern
+- Small, focused components
+- Props-based configuration
+- Utility function composition (`cn()` from `@/lib/utils` - likely clsx + tailwind-merge)
+- Forward refs for form components
+
+### Dialog Component
+**File**: `apps/web/components/ui/dialog.tsx`
+- Custom implementation (not Radix)
+- Features:
+  - Backdrop overlay (fixed, z-50, black/80)
+  - Center content positioning
+  - Close on backdrop click
+  - Body overflow hidden when open
+  - Composable parts: Dialog, DialogContent, DialogHeader, DialogTitle, DialogDescription, DialogFooter
+
+---
+
+## 5. Next.js Image Usage Patterns
+
+### Configuration
+**File**: `apps/web/next.config.js`
+```javascript
+images: {
+  remotePatterns: [
+    { protocol: 'https', hostname: '**' },  // All HTTPS domains allowed
+  ],
+}
+```
+
+### Usage Pattern in Components:
+```typescript
+import Image from 'next/image';
+
+// Main image (fill layout)
+<Image
+  src={images[selectedIndex]?.url ?? ''}
+  alt={`Ảnh ${selectedIndex + 1}`}
+  fill
+  sizes="(max-width: 768px) 100vw, 60vw"
+  className="object-cover"
+  priority={selectedIndex === 0}
+/>
+
+// Thumbnail (fixed size)
+<Image
+  src={img.url}
+  alt={`Thumbnail ${index + 1}`}
+  fill
+  sizes="64px"
+  className="object-cover"
+/>
+
+// Property card (fill layout)
+<Image
+  src={listing.property.media[0]?.url ?? ''}
+  alt={`Ảnh bất động sản: ${listing.property.title}`}
+  fill
+  sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
+  className="object-cover transition-transform group-hover:scale-105"
+/>
+```
+
+### Best Practices Observed:
+✓ Always provide `alt` text  
+✓ Use responsive `sizes` prop  
+✓ Use `fill` layout with `object-cover`  
+✓ Set `priority={true}` for above-fold images  
+✓ Use aspect ratio containers (aspect-video, aspect-square, etc.)
+
+---
+
+## 6. State Management Patterns
+
+### Using Zustand
+
+#### Auth Store
+**File**: `apps/web/lib/auth-store.ts`
+```typescript
+const useAuthStore = create<AuthState>((set, get) => ({
+  user: null,
+  isAuthenticated: false,
+  isLoading: false,
+  error: null,
+
+  login: async (data) => { /* ... */ },
+  logout: async () => { /* ... */ },
+  fetchProfile: async () => { /* ... */ },
+  initialize: async () => { /* ... */ },
+}));
+```
+
+#### Comparison Store (with persistence)
+**File**: `apps/web/lib/comparison-store.ts`
+```typescript
+export const useComparisonStore = create<ComparisonState>()(
+  persist(
+    (set, get) => ({
+      selectedIds: [],
+      listings: [],
+      isLoading: false,
+      error: null,
+
+      addToCompare: (id: string) => { /* ... */ },
+      removeFromCompare: (id: string) => { /* ... */ },
+      isSelected: (id: string) => { /* ... */ },
+      setListings: (listings: ListingDetail[]) => { /* ... */ },
+      setLoading: (loading: boolean) => { /* ... */ },
+      setError: (error: string | null) => { /* ... */ },
+    }),
+    {
+      name: 'goodgo-compare',
+      partialize: (state) => ({ selectedIds: state.selectedIds }),
+    }
+  )
+);
+```
+
+### Store Patterns:
+- **Actions as methods** in store object
+- **Async support** with `set()` and `get()`
+- **Persistence middleware** for localStorage (comparison store)
+- **Error handling** with dedicated error fields
+- **Loading states** for async operations
+
+### Hooks Pattern
+**File**: `apps/web/lib/hooks/`
+```
+use-analytics.ts
+use-listings.ts      # Likely wraps API calls
+use-payments.ts
+use-saved-searches.ts
+use-subscription.ts
+use-valuation.ts
+```
+
+These likely use React Query + custom Zustand stores
+
+---

+## 11. Key Insights & Best Practices
+
+### Image Strategy
+1. **Responsive Images**: Uses `sizes` prop for responsive serving
+2. **Lazy Loading**: Non-priority images load on demand
+3. **Performance**: Object-fit cover with aspect ratios
+4. **SEO**: First image used for OG tags in metadata
+5. **No 3rd-party**: Custom gallery implementation = lightweight
+
+### Component Architecture
+1. **Separation of Concerns**: Server fetch → Client interactivity
+2. **Dynamic Imports**: Heavy components (Map) loaded on demand
+3. **Composition**: Small, reusable UI components with variants
+4. **Type Safety**: Full TypeScript with Zod validation
+
+### State Management
+1. **Zustand for Global State**: Auth, Comparisons
+2. **React Query**: Likely for server state (data fetching)
+3. **Local State**: For UI state (gallery index, form inputs)
+
+### i18n
+- Vietnamese (vi) and English (en) support
+- Labels: `@/lib/validations/listings` for property types, directions, etc.
+
+### SEO
+- JSON-LD schema for listings and breadcrumbs
+- Open Graph and Twitter Cards
+- Canonical URLs
+- Alternate language links
+
+---
+
+## 12. Dependencies Not Present
+
+⚠️ **Potential Opportunities** (if needed):
+- No full-featured carousel library (could use embla-carousel if complex carousel needed)
+- No lightbox library (current implementation is basic - consider if modal zoom needed)
+- No image optimization service (relying on Next.js Image component)
+- No form builder library (using react-hook-form + manual forms)
+- No animation library (using Tailwind animations)
+- No virtualization (could add if listing 1000s of items)

+   └─ <ListingDetailClient listing={data} />
+      └─ <ImageGallery media={property.media} />
+```
+
+---
+
+## 🖼️ Working with Images
+
+### Current Gallery Features
+```typescript
+// apps/web/components/listings/image-gallery.tsx
+
+interface ImageGalleryProps {
+  media: PropertyMedia[];
+  className?: string;
+}
+
+// Features:
+// ✓ Main image (16:9 aspect ratio)
+// ✓ Previous/Next buttons
+// ✓ Image counter badge
+// ✓ Horizontal scrollable thumbnails (64x64px)
+// ✓ Selected state highlighting
+// ✓ Empty state fallback
+```
+
+### Data Structure
+```typescript
+interface PropertyMedia {
+  id: string;
+  url: string;              // Full URL to image
+  type: 'image' | 'video';  // Media type filter
+  order: number;            // Sort order (0, 1, 2...)
+  caption: string | null;   // Optional caption
+}
+
+interface Property {
+  // ... other fields
+  media: PropertyMedia[];   // Array of images/videos
+}
+```
+
+### Using Images in Components
+```typescript
+// ✓ Import Next.js Image
+import Image from 'next/image';
+
+// ✓ Main image with fill layout (responsive)
+<Image
+  src={images[index]?.url}
+  alt={`Image ${index + 1}`}
+  fill
+  sizes="(max-width: 768px) 100vw, 60vw"
+  className="object-cover"
+  priority={index === 0}
+/>
+
+// ✓ Fixed-size thumbnail
+<Image
+  src={img.url}
+  alt={`Thumbnail ${i}`}
+  fill
+  sizes="64px"
+  className="object-cover"
+/>
+
+// ✓ Responsive property card
+<Image
+  src={media[0]?.url}
+  alt="Property"
+  fill
+  sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
+  className="object-cover transition-transform group-hover:scale-105"
+/>
+```
+
+### Image Upload API
+```typescript
+// From: apps/web/lib/listings-api.ts
+
+const listingsApi = {
+  uploadMedia: async (
+    listingId: string, 
+    file: File, 
+    caption?: string
+  ) => {
+    const formData = new FormData();
+    formData.append('file', file);
+    if (caption) formData.append('caption', caption);
+    
+    // POST /api/v1/listings/{listingId}/media
+    // Returns: { mediaId: string; url: string }
+  },
+};
+```
+
+### File Upload Component (for reference)
+```typescript
+// apps/web/components/listings/image-upload.tsx
+
+interface ImageFile {
+  file: File;
+  preview: string;
+}
+
+// Usage:
+<ImageUpload 
+  images={images}
+  onChange={(newImages) => setImages(newImages)}
+  maxFiles={20}
+/>
+
+// Validation:
+// ✓ Types: JPEG, PNG, WebP
+// ✓ Max size: 10MB per file
+// ✓ Max count: 20 files
+// ✓ Drag & drop support
+// ✓ Preview grid with delete button
+```
+

+
+## 🎨 Styling Patterns
+
+### Aspect Ratios (Tailwind)
+```html
+<!-- 16:9 (videos, main images) -->
+<div class="aspect-video"><!-- 1.777:1 --></div>
+
+<!-- 4:3 (property cards) -->
+<div class="aspect-[4/3]"><!-- 1.333:1 --></div>
+
+<!-- 16:10 (compact property cards) -->
+<div class="aspect-[16/10]"><!-- 1.6:1 --></div>
+
+<!-- Square (thumbnails) -->
+<div class="aspect-square"><!-- 1:1 --></div>
+```
+
+### Image Container Pattern
+```jsx
+<div className="relative aspect-video overflow-hidden rounded-lg bg-muted">
+  <Image
+    src={url}
+    alt="description"
+    fill
+    sizes="(max-width: 768px) 100vw, 60vw"
+    className="object-cover"
+    priority={isMainImage}
+  />
+</div>
+```
+
+### Common Tailwind Classes
+```
+// Layout
+aspect-video         # 16:9 ratio
+aspect-square        # 1:1 ratio
+relative / absolute  # Positioning
+fill                 # Object-fit with aspect ratio
+
+// Styling
+object-cover         # Image fit (crop to fill)
+object-contain       # Image fit (preserve ratio)
+rounded-lg           # Border radius
+bg-muted            # Placeholder background
+
+// Interactive
+transition-colors    # Smooth color changes
+group-hover:scale-105 # Hover effect
+opacity-70          # Partial transparency
+
+// Overlay
+absolute inset-0    # Full coverage overlay
+bg-black/50         # Semi-transparent black
+hover:bg-black/70   # Darker on hover
+```
+
+---
+
+## 🔄 State Management
+
+### Zustand Store Pattern
+```typescript
+import { create } from 'zustand';
+import { persist } from 'zustand/middleware';
+
+// Simple store
+const useMyStore = create<MyState>((set, get) => ({
+  count: 0,
+  increment: () => set((state) => ({ count: state.count + 1 })),
+  asyncAction: async () => {
+    set({ isLoading: true });
+    // ... async work
+    set({ data: result, isLoading: false });
+  },
+}));
+
+// Store with persistence
+const useComparisonStore = create<State>()(
+  persist(
+    (set, get) => ({
+      // store logic
+    }),
+    {
+      name: 'storage-key',
+      partialize: (state) => ({ selectedIds: state.selectedIds }),
+    }
+  )
+);
+
+// Usage in component
+const count = useMyStore((state) => state.count);
+const increment = useMyStore((state) => state.increment);
+```
+
+### Image Gallery Local State
+```typescript
+const [selectedIndex, setSelectedIndex] = React.useState(0);
+
+const handleNext = () => {
+  setSelectedIndex((i) => (i < images.length - 1 ? i + 1 : 0));
+};
+
+const handlePrev = () => {
+  setSelectedIndex((i) => (i > 0 ? i - 1 : images.length - 1));
+};
+```
+
+---
+
+## 🧩 UI Component Patterns
+
+### Button Component (with variants)
+```typescript
+// From: apps/web/components/ui/button.tsx
+
+import { Button } from '@/components/ui/button';
+
+// Variants:
+<Button variant="default">Default</Button>      // Primary
+<Button variant="outline">Outline</Button>      // Border
+<Button variant="secondary">Secondary</Button>  // Secondary color
+<Button variant="destructive">Delete</Button>   // Red
+<Button variant="ghost">Ghost</Button>          // No background
+<Button variant="link">Link</Button>            // Text link
+
+// Sizes:
+<Button size="default">Default</Button>  // 40px height
+<Button size="sm">Small</Button>         // 36px height
+<Button size="lg">Large</Button>         // 44px height
+<Button size="icon">Icon</Button>        // Square button
+```
+
+### Badge Component (with variants)
+```typescript
+import { Badge } from '@/components/ui/badge';
+
+<Badge variant="default">Primary</Badge>

+### Card Component
+```typescript
+import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';
+
+<Card>
+  <CardHeader>
+    <CardTitle>Title</CardTitle>
+  </CardHeader>
+  <CardContent>
+    {/* content */}
+  </CardContent>
+</Card>
+```
+
+### Dialog/Modal Pattern
+```typescript
+import { Dialog, DialogContent, DialogHeader, DialogTitle } from '@/components/ui/dialog';
+
+const [isOpen, setIsOpen] = React.useState(false);
+
+<Dialog open={isOpen} onOpenChange={setIsOpen}>
+  <DialogContent>
+    <DialogHeader>
+      <DialogTitle>Dialog Title</DialogTitle>
+    </DialogHeader>
+    {/* content */}
+  </DialogContent>
+</Dialog>
+```
+
+---
+
+## 📱 Responsive Design
+
+### Breakpoints
+```css
+xs: 0px      /* Default */
+sm: 640px    /* Mobile landscape */
+md: 768px    /* Tablet */
+lg: 1024px   /* Desktop */
+xl: 1280px   /* Wide desktop */
+2xl: 1536px  /* Ultra-wide */
+```
+
+### Common Patterns
+```jsx
+// Mobile-first
+<div className="w-full sm:w-1/2 md:w-1/3 lg:w-1/4">
+  
+// Conditional display
+<div className="hidden md:block">Show on tablet+</div>
+<div className="block md:hidden">Show on mobile</div>
+
+// Responsive grid
+<div className="grid grid-cols-2 sm:grid-cols-3 md:grid-cols-4 gap-4">
+
+// Responsive text size
+<p className="text-sm md:text-base lg:text-lg">
+
+// Responsive padding
+<div className="p-4 sm:p-6 md:p-8">
+```
+
+---
+
+## 🔗 Common Imports
+
+### Essential Imports
+```typescript
+// Components
+import Image from 'next/image';
+import Link from 'next/link';
+import dynamic from 'next/dynamic';
+
+// UI Components
+import { Button } from '@/components/ui/button';
+import { Badge } from '@/components/ui/badge';
+import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';
+import { Dialog, DialogContent, DialogHeader, DialogTitle } from '@/components/ui/dialog';
+
+// Utilities
+import { cn } from '@/lib/utils';
+import { formatPrice, formatPricePerM2 } from '@/lib/currency';
+
+// State & API
+import { useAuthStore } from '@/lib/auth-store';
+import { useComparisonStore } from '@/lib/comparison-store';
+import { listingsApi } from '@/lib/listings-api';
+
+// Hooks
+import * as React from 'react';
+import { useCallback, useEffect, useState } from 'react';
+```
+
+---
+
+## 📊 Data Fetching
+
+### Server-side Fetching
+```typescript
+// apps/web/lib/listings-server.ts
+import { fetchListingById } from '@/lib/listings-server';
+
+// In page.tsx (Server Component)
+const listing = await fetchListingById(params.id);
+if (!listing) notFound();
+```
+
+### Client-side API
+```typescript
+// apps/web/lib/listings-api.ts
+import { listingsApi } from '@/lib/listings-api';
+
+// Usage:
+const listing = await listingsApi.getById(id);
+const results = await listingsApi.search({ city: 'Ho Chi Minh' });
+```
+
+### React Query Usage (likely)
+```typescript
+// Typical pattern for fetching
+import { useQuery } from '@tanstack/react-query';
+
+const { data, isLoading, error } = useQuery({
+  queryKey: ['listing', id],
+  queryFn: () => listingsApi.getById(id),
+});
+```
+
+---
+
+## 🌐 Internationalization
+
+### Language Support
+- Vietnamese (vi)
+- English (en)
+
+### Using i18n
+```typescript
+// In components, use Vietnamese labels directly or from constants
+const PROPERTY_TYPES: Record<string, string> = {
+  APARTMENT: 'Căn hộ',
+  HOUSE: 'Nhà riêng',
+  VILLA: 'Biệt thự',
+  // ...
+};
+
+// From @/lib/validations/listings
+import { PROPERTY_TYPES, DIRECTIONS, TRANSACTION_TYPES } from '@/lib/validations/listings';
+```
+
+### Language-aware Routes
+```
+/vi/listings/123   # Vietnamese
+/en/listings/123   # English
+```
+
+---
+
+## 🔐 Security Features
+
+### CSP Headers (next.config.js)
+```javascript
+img-src 'self' data: blob: https://*.mapbox.com https://
+font-src 'self' data:
+```
+
+### Image Domain Whitelist
+```javascript
+// Allows HTTPS images from any domain
+remotePatterns: [
+  { protocol: 'https', hostname: '**' }
+]
+```
+
+---
+
+## 🧪 Testing Considerations
+
+### Component Files to Test
+- `image-gallery.tsx` - Gallery navigation, state changes
+- `image-upload.tsx` - File validation, drag-drop
+- `property-card.tsx` - Image display, responsive
+- `listing-detail-client.tsx` - Overall page functionality
+
+### Test Patterns
+```typescript
+// Mock Next.js Image component
+jest.mock('next/image', () => ({
+  __esModule: true,
+  default: (props) => <img {...props} />,
+}));
+
+// Mock Zustand stores
+jest.mock('@/lib/auth-store', () => ({
+  useAuthStore: jest.fn(),
+}));
+```
+
+---
+
+## 🚀 Performance Optimization Tips
+
+1. **Image Priority**
+   ```typescript
+   priority={selectedIndex === 0}  // First image loads with page
+   ```
+
+2. **Responsive Sizes**
+   ```typescript
+   sizes="(max-width: 768px) 100vw, 60vw"  // Tells browser image width
+   ```
+
+3. **Lazy Loading**
+   - Thumbnails load on demand (no priority set)
+   - Reduces initial page weight
+
+4. **Dynamic Imports**
+   ```typescript
+   const ListingMap = dynamic(() => import('@/components/map/listing-map'), {
+     ssr: false,
+     loading: () => <div>Loading...</div>,
+   });
+   ```
+
+5. **Object URLs Cleanup**
+   ```typescript
+   React.useEffect(() => {
+     return () => {
+       images.forEach((img) => URL.revokeObjectURL(img.preview));
+     };
+   }, []);
+   ```
+
+---
+
+## 📋 Common Tasks
+
+### Add a New UI Element
+1. Create in `components/ui/ComponentName.tsx`
+2. Use CVA for variants
+3. Export from the same file
+4. Import and use in feature components
+
+### Add a New Feature Component
+1. Create in `components/feature-name/ComponentName.tsx`
+2. Make 'use client' if interactive
+3. Import UI components
+4. Use Zustand stores if needed global state
+5. Use local state for UI state
+
+### Modify Image Gallery
+1. Edit `components/listings/image-gallery.tsx`
+2. Update PropertyMedia interface if needed (in `lib/listings-api.ts`)
+3. Adjust aspect ratio / sizes as needed
+4. Test responsive behavior
+
+### Add Image Lightbox
+1. Choose library (embla-carousel, yet-another-react-lightbox, etc.)
+2. Install: `pnpm add package-name -F @goodgo/web`
+3. Create wrapper component in `components/listings/image-lightbox.tsx`
+4. Integrate with `image-gallery.tsx`
+5. Test with multiple images
+
+---
+
+## 🐛 Common Issues & Solutions
+
+### Image Not Loading
+- Check URL is valid and HTTPS
+- Verify domain in `remotePatterns`
+- Check CSP headers allow the domain
+
+### Gallery Navigation Frozen
+- Check `selectedIndex` state updates
+- Verify onClick handlers are properly bound
+- Check for JavaScript errors in console
+
+### Thumbnail Scroll Issues
+- Ensure parent container has `overflow-x-auto`
+- Check flex properties on thumbnails
+- Verify width constraints (flex-shrink-0)
+
+### Layout Shifting on Image Load
+- Use aspect ratio container
+- Set explicit width/height
+- Use `fill` layout with container

+   - DTO validation helper tests
+
+## Quick Start
+
+### For a quick overview:
+1. Read the **Quick Reference** first (5-10 minutes)
+2. Identify which file type you want to test
+3. Jump to the appropriate section in **TEST_TEMPLATES.md**
+4. Copy the template and adapt it to your file
+
+### For comprehensive understanding:
+1. Start with the **Quick Reference** overview
+2. Read the relevant module section in **TEST_COVERAGE_ANALYSIS.md**
+3. Use **TEST_TEMPLATES.md** as implementation guide
+4. Reference the example test patterns in the Analysis document
+
+## File Organization by Module
+
+### Inquiries Module (4 files)
+```
+✗ prisma-inquiry.repository.ts     — 6 methods, pagination, relationships
+✗ inquiries.controller.ts           — 4 endpoints, guards
+✗ create-inquiry.dto.ts             — 3 validations
+✗ list-inquiries.dto.ts             — 2 validations (pagination)
+```
+
+### Leads Module (6 files)
+```
+✗ prisma-lead.repository.ts         — 6 methods, stats aggregation
+✗ lead-score.vo.ts                  — Range validation (0-100)
+✗ leads.controller.ts               — 5 endpoints, role guards
+✗ create-lead.dto.ts                — 6 validations
+✗ list-leads.dto.ts                 — Status enum, pagination
+✗ update-lead-status.dto.ts         — Status enum
+```
+
+### Reviews Module (5 files)
+```
+✗ prisma-review.repository.ts       — 7 methods, distribution stats
+✗ rating.vo.ts                      — Integer range validation (1-5)
+✗ reviews.controller.ts             — 5 endpoints, mixed auth
+✗ create-review.dto.ts              — 4 validations
+✗ list-reviews.dto.ts               — 2 DTO classes, pagination
+```
+
+## Testing Priority Levels
+
+### 🔴 CRITICAL (Business Logic)
+1. **PrismaReviewRepository.getStats()** — Distribution calculation is complex
+2. **PrismaLeadRepository.getStatsByAgent()** — Conversion rate formula
+3. **Rating.vo** — Must validate 1-5 integers only
+4. **LeadScore.vo** — Must validate 0-100 range
+
+**Start here** — These are the most business-critical validations
+
+### 🟡 HIGH (Data Integrity)
+1. Repository CRUD operations
+2. Pagination calculations
+3. Relationship mapping (user joins, listing traversal)
+4. Controller command/query dispatch
+
+**Test second** — These ensure data consistency
+
+### 🟢 MEDIUM (Validation & Guards)
+1. DTO field validations
+2. Enum constraints
+3. Optional field handling
+4. Authentication/Authorization guards
+
+**Test last** — These are framework-level concerns
+
+## Test Execution Roadmap
+
+### Week 1: Value Objects & DTOs (8-10 test files)
+- [ ] LeadScore.vo.ts (1 file, 4-5 test cases)
+- [ ] Rating.vo.ts (1 file, 4-5 test cases)
+- [ ] All 10 DTO files (using templates, minimal variations)
+
+**Estimated time:** 3-5 hours total
+
+### Week 2: Controllers (2 test files)
+- [ ] InquiriesController (4 endpoints + guards)
+- [ ] LeadsController (5 endpoints + guards)
+- [ ] ReviewsController (5 endpoints + mixed auth)
+
+**Estimated time:** 2-3 hours total
+
+### Week 3: Repositories (3 test files)
+- [ ] PrismaInquiryRepository (6 methods)
+- [ ] PrismaLeadRepository (6 methods + aggregation)
+- [ ] PrismaReviewRepository (7 methods + distribution)
+
+**Estimated time:** 4-6 hours total
+
+### Total Estimated Time: 9-14 hours
+
+## Key Testing Patterns
+
+### Repositories
+```typescript
+// Mock all Prisma methods in beforeEach
+mockPrisma = {
+  [model]: { 
+    findUnique: vi.fn(), 
+    findMany: vi.fn(), 
+    create: vi.fn(), 
+    update: vi.fn(), 
+    count: vi.fn() 
+  }
+};
+
+// Test happy path and error cases
+// Verify pagination calculations
+// Verify data transformation (toDomain)
+```
+
+### Value Objects
+```typescript
+// Test valid cases
+const result = ValueObject.create(validValue);
+expect(result.isOk()).toBe(true);
+
+// Test invalid cases
+const result = ValueObject.create(invalidValue);
+expect(result.isErr()).toBe(true);
+expect(result.unwrapErr()).toBe('error message');
+```
+
+### DTOs
+```typescript
+// Use validate() from class-validator
+const errors = await validate(dto);
+expect(errors).toHaveLength(0); // or > 0 for invalid cases
+
+// Test type transformation with class-transformer
+// Test optional field handling
+```
+
+### Controllers
+```typescript
+// Mock CommandBus and QueryBus
+mockCommandBus.execute.mockResolvedValue(expectedResult);
+
+// Verify command/query construction
+const command = mockCommandBus.execute.mock.calls[0][0];
+expect(command.userId).toBe(expectedUserId);
+```
+
+## Critical Formulas to Test
+
+### Pagination
+```
+skip = (page - 1) * take
+totalPages = Math.ceil(total / take)
+take = Math.min(limit, 100)  // Clamped to 100 max
+```
+
+### Lead Statistics
+```
+conversionRate = (CONVERTED_count / total_leads) * 100  // 2 decimals
+avgScore = (sum_of_scores / non_null_count)            // 1 decimal, null if no scores
+```
+
+### Review Statistics
+```
+averageRating = (sum_of_ratings / total_reviews)       // 1 decimal
+distribution = { 1: count, 2: count, 3: count, 4: count, 5: count }
+```
+
+## Import Statements You'll Need
+
+```typescript
+// Testing utilities
+import { describe, it, expect, beforeEach, vi } from 'vitest';
+import { validate } from 'class-validator';
+import { plainToClass } from 'class-transformer';
+
+// NestJS utilities (for controller tests)
+import type { EventBus, CommandBus, QueryBus } from '@nestjs/cqrs';
+
+// Domain classes
+import { InquiryEntity } from './domain/entities/inquiry.entity';
+import { LeadEntity } from './domain/entities/lead.entity';
+import { ReviewEntity } from './domain/entities/review.entity';
+import { LeadScore } from './domain/value-objects/lead-score.vo';
+import { Rating } from './domain/value-objects/rating.vo';
+```
+
+## Common Test Data
+
+### User IDs
+```
+user-1, user-2, user-3, user-agent-1
+```
+
+### Lead Statuses
+```
+NEW, CONTACTED, QUALIFIED, NEGOTIATING, CONVERTED, LOST
+```
+
+### Pagination Defaults
+```
+page: 1, limit: 20 (max 100)
+```
+
+### Rating Range
+```
+1-5 stars (integer only)
+```
+
+### Lead Score Range
+```
+0-100 (any number)
+```
+
+## References
+
+### Existing Test Files (Use as Reference)
+- `src/modules/inquiries/application/__tests__/create-inquiry.handler.spec.ts` (20 lines pattern)
+- `src/modules/leads/application/__tests__/create-lead.handler.spec.ts` (20 lines pattern)
+- `src/modules/reviews/presentation/__tests__/reviews.controller.spec.ts` (135 lines pattern)
+
+### Full Implementations
+All 17 file implementations are in `TEST_COVERAGE_ANALYSIS.md` with line-by-line explanations.
+
+## Troubleshooting
+
+### Issue: "Cannot find module" when mocking
+**Solution:** Use `as any` casting for mocked dependencies
+```typescript
+const repo = new PrismaInquiryRepository(mockPrisma as any);
+```
+
+### Issue: Validation tests not working
+**Solution:** Make sure you're using `plainToClass` for DTOs with transformers
+```typescript
+const dto = plainToClass(CreateLeadDto, plainObject);
+```
+
+### Issue: Pagination calculations don't match
+**Solution:** Remember that limit is clamped to 100
+```typescript
+const take = Math.min(limit, 100);  // Always do this
+```
+
+### Issue: Stats calculations have rounding errors
+**Solution:** Check decimal place requirements:
+- conversionRate: 2 decimals (multiply by 10000, divide by 100)
+- avgScore: 1 decimal (multiply by 10, divide by 10)
+- averageRating: 1 decimal (multiply by 10, divide by 10)
+
+## Next Steps
+
+1. **Pick your starting file** from Week 1 (recommend LeadScore.vo first — simplest)
+2. **Open the template** matching that file type in TEST_TEMPLATES.md
+3. **Copy the template** to your test file location
+4. **Adapt the template** with your specific imports and data
+5. **Run tests** and verify they pass
+6. **Move to next file** following the roadmap

+- [ ] I've read TESTING_INDEX.md
+- [ ] I understand the 3 file categories (repos, VOs, DTOs, controllers)
+- [ ] I've identified which file I want to test
+- [ ] I have the template copied from TEST_TEMPLATES.md
+- [ ] I've read my file's implementation in TEST_COVERAGE_ANALYSIS.md
+- [ ] I understand what methods need testing
+- [ ] I'm ready to write tests!
+
+---
+
+## 💡 Quick Tips
+
+1. **Start with Value Objects** (LeadScore.vo, Rating.vo) — They're the simplest
+2. **Use the templates** — Don't write from scratch
+3. **Test one file at a time** — Don't jump around
+4. **Read the test scenarios** — They tell you what to test
+5. **Verify the formulas** — Stats calculations are critical

+2. **Copy-Paste**: Use templates, don't write from scratch
+3. **Test Early**: Run tests as you write them
+4. **Be Thorough**: Include both happy and error paths
+5. **Use Existing**: Reference existing tests in the codebase
+6. **Verify Formulas**: Test arithmetic calculations carefully
+7. **Mock Everything**: Don't hit real database in tests

+
+**Key Methods to Test:**
+- `findById()` - Returns inquiry by ID or null if not found
+- `save()` - Creates new inquiry record
+- `markAsRead()` - Updates isRead flag
+- `findByListing()` - Paginated query by listing, includes relationships
+- `findByAgent()` - Paginated query through listing agent relationship
+- `countUnreadByAgent()` - Aggregation query for unread count
+- `toDomain()` - Private mapper converting Prisma model to domain entity
+
+**Test Scenarios:**
+- All methods with valid inputs
+- Null returns (no matching records)
+- Pagination edge cases (page bounds, limit clamping)
+- Data mapping accuracy (ISO dates, relationship joins)

+- `getStatsByAgent()` - Aggregates by status, calculates conversion rate and avg score
+- `toDomain()` - Maps Prisma model including LeadScore VO instantiation
+
+**Test Scenarios:**
+- CRUD operations
+- Optional score handling (null and valid values)
+- Status filtering in paginated query
+- Stats calculations (zero leads, no scores, conversion rate precision)
+- Pagination edge cases

+**Validation Rules:**
+- Value must be integer between 0 and 100 inclusive
+
+**Test Scenarios:**
+- Valid scores (0, 50, 100)

+
+**Key Methods to Test:**
+- `findById()` - Returns review or null
+- `findByUserAndTarget()` - Unique constraint check
+- `save()` - Creates review with optional comment
+- `delete()` - Deletes review
+- `findByTarget()` - Paginated list with user join
+- `findByUserId()` - Paginated list by user
+- `getStats()` - Calculates average rating and distribution
+- `toDomain()` - Maps Prisma model including Rating VO
+
+**Test Scenarios:**
+- All CRUD operations
+- Optional comment handling
+- Pagination with relationships (user fullName join)
+- Stats with distribution calculation (1-5 scale)
+- Zero reviews edge case
+- Data accuracy (ISO dates, decimal rounding)
+
+---
+
+## 3.2 Rating Value Object
+
+**File:** `src/modules/reviews/domain/value-objects/rating.vo.ts`
+

+interface RatingProps {
+  value: number;
+}
+
+export class Rating extends ValueObject<RatingProps> {
+  get value(): number { return this.props.value; }
+
+  static create(value: number): Result<Rating, string> {
+    if (!Number.isInteger(value) || value < 1 || value > 5) {
+      return Result.err('Đánh giá phải từ 1 đến 5 sao');
+    }
+    return Result.ok(new Rating({ value }));
+  }
+}
+```
+
+**Validation Rules:**
+- Must be integer between 1 and 5 inclusive
+
+**Test Scenarios:**
+- Valid ratings (1-5)

+
+**Key Endpoints to Test:**
+- `POST /reviews` - Create with optional comment
+- `GET /reviews` - List by target (no auth required)
+- `GET /reviews/stats` - Stats for target (no auth required)
+- `GET /reviews/me` - List user's reviews (requires auth)
+- `DELETE /reviews/:id` - Delete review (requires auth)
+
+**Test Scenarios:**
+- Command/query dispatch with correct parameters
+- Default pagination (1, 20)
+- Null comment handling
+- Auth requirements (JWT for POST, GET /me, DELETE; no auth for GET, GET/stats)
+- Return types (deleted: true)

+**Pattern Insights:**
+- Uses `vi.fn()` from Vitest for mocking
+- Mock all repository methods in beforeEach
+- Test happy path with all dependencies mocked
+- Test error scenarios (NotFoundException)
+- Verify side effects (event publishing)
+- Uses exact parameter checking or matchers (`expect.objectContaining`)

+    await expect(handler.execute(command)).rejects.toThrow(
+      'Điểm lead phải từ 0 đến 100',
+    );
+    expect(mockLeadRepo.save).not.toHaveBeenCalled();
+  });
+});
+```
+
+**Additional Pattern Notes:**
+- Tests optional parameter handling (score: null)
+- Tests validation errors from value objects (LeadScore)
+- Uses same mock setup structure as inquiry handler

+
+## Quick Test Scenarios by Type
+
+### REPOSITORIES (3 files)
+Test checklist for each repository:
+- [ ] findById() returns entity or null
+- [ ] save() creates record with correct data mapping
+- [ ] Paginated methods respect limit cap (100 max)
+- [ ] Pagination calculation: skip = (page - 1) * take
+- [ ] Relationships are joined correctly
+- [ ] Aggregations calculate correctly (stats methods)
+- [ ] Optional fields handling (null coercion)
+- [ ] ISO date formatting in DTOs
+
+**Specific to PrismaInquiryRepository:**
+- countUnreadByAgent() aggregation
+- findByListing() includes property.title
+- findByAgent() joins through listing.agentId
+
+**Specific to PrismaLeadRepository:**
+- findByAgent() optional status filter
+- getStatsByAgent() calculates:
+  - totalLeads count
+  - byStatus object (dict of counts)
+  - conversionRate: (CONVERTED / total) * 100 (2 decimals)
+  - avgScore: average of non-null scores (1 decimal)
+
+**Specific to PrismaReviewRepository:**
+- findByUserAndTarget() unique constraint query
+- getStats() builds distribution object (keys 1-5)
+- averageRating calculation: (sum / total) * 10 / 10 (1 decimal)
+
+---
+
+### VALUE OBJECTS (2 files)
+Test checklist:
+- [ ] create() with valid value returns Result.ok()
+- [ ] create() with invalid value returns Result.err() with correct message
+- [ ] Getter returns props.value
+- [ ] Invalid cases covered (negative, > max, non-integer, null)
+
+**LeadScore validation:**
+```
+✓ Valid: 0, 50, 100
+✗ Invalid: -1, 101, 2.5, null, "50"
+Error: "Điểm lead phải từ 0 đến 100"
+```
+
+**Rating validation:**
+```
+✓ Valid: 1, 2, 3, 4, 5
+✗ Invalid: 0, 6, 2.5, null, "5"
+Error: "Đánh giá phải từ 1 đến 5 sao"
+```
+
+---
+
+### CONTROLLERS (2 files)
+Test checklist:
+- [ ] Each endpoint dispatches correct command/query type
+- [ ] Parameters are mapped correctly from DTO
+- [ ] Optional fields become null (e.g., phone ?? null → null)
+- [ ] Default pagination values applied (page: 1, limit: 20)
+- [ ] CurrentUser decorator extracts user.sub correctly
+- [ ] Guard enforcement (@UseGuards, @Roles)
+- [ ] Return types match (e.g., { deleted: true })
+
+**InquiriesController specifics:**
+- POST /inquiries: phone optional → null
+- GET /inquiries/listing/:listingId: requires JWT
+- GET /inquiries/agent/me: requires JWT + AGENT role
+- PATCH /inquiries/:id/read: requires JWT + AGENT role
+
+**LeadsController specifics:**
+- ALL endpoints require JWT + AGENT role (class-level @Roles)
+- POST /leads: score optional, score range validation in command
+- GET /leads: status filter optional
+- GET /leads/stats: aggregation query
+- PATCH /leads/:id/status: only status field in command
+- DELETE /leads/:id: agentId verification in command
+
+**ReviewsController specifics:**
+- POST /reviews: requires JWT (AuthGuard)
+- GET /reviews: NO auth required (stats are public)
+- GET /reviews/stats: NO auth required
+- GET /reviews/me: requires JWT
+- DELETE /reviews/:id: requires JWT + ownership check in command
+
+---
+
+### DTOs (10 files)
+Test checklist:
+- [ ] Required fields throw ValidationException if missing
+- [ ] String max/min length validated
+- [ ] Number min/max validated
+- [ ] Enum @IsIn() validates allowed values
+- [ ] Type transformation (class-transformer @Type)
+- [ ] Email format validated (@IsEmail)
+- [ ] Optional fields (@IsOptional) don't throw if omitted
+
+**Pagination standard (used in 5 DTOs):**
+- page: optional, @Min(1), default 1
+- limit: optional, @Min(1), @Max(100), default 20
+- Both use @Type(() => Number) for string→number transformation
+
+**Enum validations:**
+- LeadStatus: ['NEW', 'CONTACTED', 'QUALIFIED', 'NEGOTIATING', 'CONVERTED', 'LOST']
+- Used in: ListLeadsDto, UpdateLeadStatusDto
+
+---
+
+## Test Priority Matrix
+
+### 🔴 CRITICAL (Business Logic)
+1. PrismaReviewRepository.getStats() - distribution calculation
+2. PrismaLeadRepository.getStatsByAgent() - conversion rate formula
+3. Rating.vo - must be 1-5 integers only
+4. LeadScore.vo - must be 0-100 range
+
+### 🟡 HIGH (Data Integrity)
+1. All repository CRUD methods
+2. Pagination calculations
+3. Relationship mapping (user joins, listing joins)
+4. Controller parameter mapping
+
+### 🟢 MEDIUM (Validation)
+1. DTO field validations
+2. Enum constraints
+3. Optional field handling
+4. Guard enforcement
+
+---
+
+## Test Execution Order Recommendation
+
+1. **Value Objects** (2 files) - 2 simple test files
+2. **DTOs** (10 files) - Use class-validator testing patterns
+3. **Controllers** (2 files) - Command/query dispatch tests
+4. **Repositories** (3 files) - Data layer tests with mocked Prisma
+
+---
+
+## Mock Setup Template
+
+### For Repositories:
+```typescript
+const mockPrisma = {
+  inquiry: { findUnique: vi.fn(), findMany: vi.fn(), create: vi.fn(), update: vi.fn(), delete: vi.fn(), count: vi.fn() },
+};
+const repo = new PrismaInquiryRepository(mockPrisma as any);
+```
+
+### For Controllers:
+```typescript
+const mockCommandBus = { execute: vi.fn() };
+const mockQueryBus = { execute: vi.fn() };
+const controller = new InquiriesController(mockCommandBus as any, mockQueryBus as any);
+```
+
+### For Value Objects:
+```typescript
+const result = LeadScore.create(75);
+expect(result.isOk()).toBe(true);
+expect(result.unwrap().value).toBe(75);
+```
+
+### For DTOs:
+```typescript
+import { validate } from 'class-validator';
+const dto = new CreateLeadDto();
+dto.name = 'Nguyễn Văn A';
+dto.phone = '0901234567';
+// ... set other required fields
+const errors = await validate(dto);
+expect(errors).toHaveLength(0);
+```
+
+---
+
+## Key Formulas to Verify
+
+### Pagination:
+```
+skip = (page - 1) * take
+totalPages = Math.ceil(total / take)
+take = Math.min(limit, 100)
+```
+
+### Lead Conversion Rate:
+```
+conversionRate = (convertedCount / totalLeads) * 100
+Result: rounded to 2 decimals (e.g., 33.33)
+```
+
+### Lead Average Score:
+```
+avgScore = scoreSum / scoreCount (where score !== null)
+Result: rounded to 1 decimal (e.g., 75.5)
+```
+
+### Review Average Rating:
+```
+averageRating = (sum / totalReviews) 
+Result: rounded to 1 decimal (e.g., 4.5)
+```
+
+### Review Distribution:
+```
+distribution: { 1: count, 2: count, 3: count, 4: count, 5: count }
+Must initialize all 5 keys, even if 0
+```
+

+
+---
+
+## Next Steps
+
+1. **Copy reference test patterns:**
+   - Create inquiry and lead handlers already have good test patterns
+   - Controller test for reviews shows endpoint testing approach
+
+2. **Start with repositories:**
+   - Most complex (Prisma mocking)
+   - Most critical (data layer)
+   - Established patterns in existing tests
+
+3. **Test DTOs second:**
+   - Quick feedback (class-validator validation)
+   - 10 files but mostly simple
+
+4. **Controllers and VOs last:**
+   - Build on repository/DTO tests
+   - Depend on handler tests (if testing full flow)

+
+## 💡 Quick Start Guide
+
+### Step 1: Choose Your Handler
+```
+reject-listing → Use approve-listing as template
+get-revenue-stats → Use get-dashboard-stats as template
+user-deactivated → Use user-banned as template
+```
+
+### Step 2: Review the Reference Test
+Read the reference test file from **DETAILED_HANDLER_COMPARISON.md**
+
+### Step 3: Copy & Adapt
+- Copy the test structure
+- Change imports
+- Adapt test data
+- Verify mock calls
+
+### Step 4: Verify Coverage
+Run: `npm test admin`

+
+---
+
+## 3. STATE MANAGEMENT
+
+### Zustand Store Implementation
+**2 Stores with Proper Typing & Persistence:**
+
+#### Auth Store (`lib/auth-store.ts`)
+```typescript
+- user: UserProfile | null
+- isAuthenticated: boolean
+- isLoading: boolean
+- error: string | null
+```
+**Methods:**
+- login(data) - Phone/password authentication
+- register(data) - New user signup
+- handleOAuthCallback(token, refreshToken) - OAuth token exchange
+- logout() - Clear session
+- refreshToken() - Token refresh on 401
+- fetchProfile() - Get current user
+- initialize() - Check auth cookie on mount
+- clearError() - Reset error state
+
+**Features:**
+- ✅ Automatic token refresh on 401 errors
+- ✅ Profile re-fetch on successful auth
+- ✅ Cookie-based authentication check
+- ✅ Graceful logout handling (clears on API failure)
+
+#### Comparison Store (`lib/comparison-store.ts`)
+```typescript
+- selectedIds: string[] (max 5 items)
+- listings: ListingDetail[] (full listing data)
+- isLoading: boolean
+- error: string | null
+```
+**Methods:**
+- addToCompare(id) - Add listing (max 5, returns boolean)
+- removeFromCompare(id) - Remove listing
+- isSelected(id) - Check if selected
+- clearAll() - Reset
+- canCompare() - Check if 2+ items
+- canAdd() - Check if <5 items
+- setListings() - Update data
+- computeComparisonStats() - Calculate price/area ranges
+
+**Features:**
+- ✅ Persisted to localStorage (goodgo-compare)
+- ✅ Type-safe statistics calculation
+- ✅ Min/max comparison logic
+- ✅ Error state management
+
+---
+
+## 4. API INTEGRATION
+
+### API Client Architecture (`lib/api-client.ts`)
+
+**Base URL:** `${NEXT_PUBLIC_API_URL}/api/v1` (default: `http://localhost:3001/api/v1`)
+
+**Features:**
+- ✅ Request method abstraction (GET, POST, PATCH, DELETE)
+- ✅ Automatic CSRF token injection for non-safe methods
+- ✅ JSON request/response handling
+- ✅ Custom ApiError class with status codes
+- ✅ Credentials included by default (cookies)
+- ✅ Content-Type: application/json
+
+**Error Handling:**
+```typescript
+class ApiError extends Error {
+  constructor(status: number, message: string)
+}
+```
+
+### API Clients (10 Specialized Modules)
+
+1. **auth-api.ts** - Register, login, refresh, logout, OAuth exchange, get profile
+2. **listings-api.ts** - Search, create, get by ID, update status, upload media
+3. **analytics-api.ts** - Market reports, heatmap data
+4. **comparison-api.ts** - Get multiple listings for comparison
+5. **payment-api.ts** - Payment processing
+6. **profile-api.ts** - User profile management
+7. **saved-search-api.ts** - Save/manage search queries
+8. **subscription-api.ts** - Plan management
+9. **valuation-api.ts** - AI property valuation
+10. **admin-api.ts** - Dashboard stats, user list, moderation queue
+
+### React Query Integration
+**Custom Hooks (`lib/hooks/`):**
+
+```typescript
+- useListingsSearch(params) - Search listings with pagination
+- useListingDetail(id) - Get single listing (enabled guard)
+- useAnalytics() - Market analytics with caching
+- usePayments() - Payment history
+- useSubscription() - Subscription details
+- useSavedSearches() - Saved search queries
+- useValuation(propertyId) - AI valuation
+```
+
+**Query Key Structure:**
+```typescript
+listingsKeys = {
+  all: ['listings'],
+  search: (params) => ['listings', 'search', params],
+  detail: (id) => ['listings', 'detail', id]
+}
+```
+
+**Provider:** `QueryProvider` wraps app with React Query client
+
+---
+
+## 5. AUTHENTICATION SYSTEM
+
+### Authentication Flow
+
+**1. Cookie-Based Session**
+- Auth cookie: `goodgo_authenticated=1`
+- Checked in middleware for route protection
+- Checked in auth-store on app initialization
+
+**2. Multi-Factor Support**
+- 🟢 Phone + Password (native)
+- 🟢 Google OAuth
+- 🟢 Zalo OAuth
+
+**3. Token Management**
+- Automatic refresh on 401 responses
+- Tokens stored in HTTP-only cookies (secure)
+- CSRF protection enabled
+
+**4. Protected Routes (Middleware)**
+```typescript
+Public: /, /login, /register, /search, /auth/callback/*
+Auth-only: /login, /register (redirects to /dashboard if authenticated)
+Protected: /dashboard/*, /admin/* (requires auth cookie)
+```
+
+**5. OAuth Callbacks**
+- `GET /auth/callback/google?code=...&state=...`
+- `GET /auth/callback/zalo?code=...`
+- Exchange code for tokens via `authApi.exchangeToken()`
+
+**Security Measures:**
+- ✅ XSRF-Token header injection (auto-detected from cookies)
+- ✅ Credentials: 'include' for cross-origin requests
+- ✅ HTTP-only cookies (if backend supports)
+- ✅ Strict SameSite policy (if configured)
+
+---
+
+## 6. UI/UX QUALITY
+
+### Accessibility Features
+
+**Semantic HTML:**
+- ✅ Proper heading hierarchy (h1 → h6)
+- ✅ `<section>` with aria-labelledby
+- ✅ Form labels properly associated
+- ✅ `<main>` with id="main-content"
+
+**ARIA Attributes:**
+- ✅ aria-label on inputs, buttons
+- ✅ aria-hidden on decorative icons
+- ✅ role="search" on filter bars
+- ✅ role="status" for loading states
+- ✅ role="alert" for error messages
+- ✅ aria-labelledby linking sections
+
+**Keyboard Navigation:**
+- ✅ Focus visible on all interactive elements
+- ✅ Focus ring styling (ring-2 ring-ring)
+- ✅ Skip to main content link (fixed position, -translate-y-16 hidden)
+- ✅ Tab order follows document flow
+
+**Example from Landing Page:**
+```tsx
+<a
+  href="#main-content"
+  className="fixed left-2 top-2 z-[100] -translate-y-16 rounded-md 
+             bg-primary px-4 py-2 text-sm font-medium text-primary-foreground 
+             shadow-lg transition-transform focus:translate-y-0"
+>
+  {t('skipToContent')}
+</a>
+```
+
+### Responsive Design
+
+**Mobile-First Approach:**
+- Base styles for mobile
+- Breakpoint utilities: sm, md, lg, xl, 2xl
+- Flexbox and Grid layouts
+- Aspect ratios for images
+
+**Examples:**
+```tsx
+// Landing page
+className="text-4xl font-bold md:text-5xl lg:text-6xl"
+
+// Search filters
+className={isSidebar ? 'w-full' : 'w-full sm:w-40'}
+
+// Comparison table
+<div className="overflow-x-auto md:overflow-x-visible">
+```
+
+**Tested Breakpoints:**
+- Mobile: 320px - 640px (sm)
+- Tablet: 640px - 1024px (md/lg)
+- Desktop: 1024px+ (xl/2xl)
+
+### Dark Mode Support
+- ✅ Theme provider using React Context
+- ✅ Respects system preference (prefers-color-scheme)
+- ✅ localStorage persistence
+- ✅ Class-based dark mode (document.documentElement.classList)
+- ✅ Tailwind dark: prefix support
+
+### Form Validation

+
+## 7. MISSING PAGES & FEATURES
+
+### Already Implemented (No Gaps)
+✅ Dashboard/Analytics - COMPLETE
+✅ Admin Dashboard - COMPLETE
+✅ Search/Listings - COMPLETE
+✅ Comparison Tool - COMPLETE
+✅ User Profiles - COMPLETE
+✅ Authentication - COMPLETE
+
+### Potentially Future Enhancements
+- [ ] Agent marketplace page (mentioned in app, not a critical page)
+- [ ] Notifications center (backend integration ready)
+- [ ] Message inbox (backend integration ready)
+- [ ] Real estate agency profiles (possible B2B feature)
+
+**Assessment:** The blueprint features are **100% implemented**. No missing critical pages.
+
+---
+
+## 8. PERFORMANCE OPTIMIZATION
+
+### Client vs Server Rendering Strategy
+
+**Server-Rendered Pages:**
+- Auth callbacks (minimal interactivity)
+- Some API routes
+
+**Client-Rendered Pages (use client):**
+- Landing page - requires interactive search form
+- Search page - requires filter state + map view
+- Dashboard pages - require interactive charts + real-time data
+- Admin pages - require dynamic data updates
+- Comparison - requires client-side stats calculation
+
+**Rationale:** Client rendering used where interactivity is essential. This is appropriate for a real estate platform.
+
+### Image Optimization
+
+**Next.js Image Configuration:**
+```typescript
+images: {
+  remotePatterns: [{
+    protocol: 'https',
+    hostname: '**',
+  }],
+}
+```
+
+**Usage in App:**
+- ✅ `Image` component used in dashboard listings
+- ✅ Property media URLs properly formatted
+- ✅ Fallback placeholders for missing images
+- ✅ Aspect ratio preservation
+
+**Optimization Opportunity:**
+⚠️ **Minor:** Consider adding `fill` prop with `sizes` attribute for responsive images:
+```typescript
+// Current
+<Image src={url} width={300} height={200} alt="property" />
+
+// Better for responsive
+<Image 
+  src={url} 
+  fill 
+  sizes="(max-width: 640px) 100vw, (max-width: 1024px) 50vw, 33vw"
+  alt="property"
+/>
+```
+
+### Code Splitting
+
+**Dynamic Imports:**
+- ✅ ListingMap component (SSR: false)
+- ✅ Charts (lazy loaded in dashboard)
+- ✅ Heavy components deferred to client
+
+```typescript
+const ListingMap = dynamic(
+  () => import('@/components/map/listing-map'),
+  { ssr: false, loading: () => <LoadingSpinner /> }
+);
+```
+
+### Performance Monitoring
+
+**Web Vitals:**
+- ✅ `web-vitals` package (v5.2.0)
+- ✅ WebVitals provider component tracks metrics
+- ✅ Sentry integration for error reporting
+
+**Metrics Tracked:**
+- CLS (Cumulative Layout Shift)
+- FID (First Input Delay)
+- LCP (Largest Contentful Paint)
+- FCP (First Contentful Paint)
+- TTFB (Time to First Byte)
+
+### Caching Strategy
+
+**HTTP Caching Headers:** Set in next.config.js
+```
+Cache-Control configured via server
+```
+
+**React Query Caching:**
+- Default staleTime: 0 (immediate revalidation)
+- Proper invalidation on mutations

+- Sentry integration for runtime monitoring
+
+⚠️ **Optimization Opportunity:**
+- Consider consolidating date handling (use date-fns if dates are used extensively)
+- Currently no date formatting library, relying on native Date methods
+
+### Scripts
+```json
+{
+  "dev": "next dev --port 3000",
+  "build": "next build",
+  "start": "next start",
+  "lint": "eslint src/ app/ components/ lib/ --no-error-on-unmatched-pattern",
+  "test": "vitest run",
+  "typecheck": "tsc --noEmit"
+}
+```
+
+---
+
+## 10. INTERNATIONALIZATION (i18n)
+
+### Configuration
+
+**Supported Locales:**
+- ✅ Vietnamese (`vi`)
+- ✅ English (`en`)
+
+**Setup:**
+- next-intl v4.9.0 with Next.js 15
+- Route prefix: `as-needed` (only for non-default locale)
+
+**Translation Files:**
+- `messages/vi.json` - 10,154 bytes (comprehensive Vietnamese)
+- `messages/en.json` - 8,698 bytes (comprehensive English)
+
+**Usage Pattern:**
+```typescript
+const t = useTranslations('search');
+// or
+const t = useTranslations(); // entire namespace
+```
+
+**Translation Keys Present:**
+- Common UI labels
+- Form validation messages
+- Error messages
+- Listing types (propertyTypes.APARTMENT, etc.)
+- Transaction types (transactionTypes.SALE, etc.)
+- Price ranges (priceRanges.under1b, etc.)
+- Admin labels
+- Landing page content
+
+**Middleware Integration:**
+```typescript
+export const middleware = (request: NextRequest) => {
+  const intlMiddleware = createIntlMiddleware(routing);
+  return intlMiddleware(request);
+}
+```
+
+---
+
+## 11. SECURITY ANALYSIS
+
+### Headers & CSP
+
+**Security Headers:**
+```
+X-Content-Type-Options: nosniff          // Prevent MIME sniffing
+X-Frame-Options: DENY                    // No iframe embedding
+X-XSS-Protection: 1; mode=block         // Legacy XSS protection
+Referrer-Policy: strict-origin-when-cross-origin
+Strict-Transport-Security: max-age=31536000 (1 year) + preload
+Permissions-Policy:
+  - camera: disabled
+  - microphone: disabled
+  - geolocation: self only
+  - payment: self only
+```
+
+**Content Security Policy:**
+```
+default-src: 'self'
+script-src: 'self' 'unsafe-inline' 'unsafe-eval' https://api.mapbox.com
+style-src: 'self' 'unsafe-inline' https://api.mapbox.com
+img-src: 'self' data: blob: https://*.mapbox.com https://*.tiles.mapbox.com https:
+font-src: 'self' data:
+connect-src: 'self' https://*.mapbox.com https://api.mapbox.com https://events.mapbox.com
+worker-src: 'self' blob:
+child-src: 'self' blob:
+frame-ancestors: 'none'
+base-uri: 'self'
+form-action: 'self'
+```
+
+**Issues Found:**
+⚠️ **UNSAFE-INLINE & UNSAFE-EVAL in CSP**
+- Currently allows inline scripts for Next.js development
+- **Recommendation:** In production, use `NEXT_STRICT_CSP_POLICY` env var
+- Configuration exists but needs to be enabled
+
+### CSRF Protection
+
+✅ **Implemented:**
+```typescript
+function getCsrfToken(): string | undefined {
+  if (typeof document === 'undefined') return undefined;
+  const match = document.cookie.match(/(?:^|;\s*)XSRF-TOKEN=([^;]*)/);
+  return match?.[1] ? decodeURIComponent(match[1]) : undefined;
+}
+
+// Auto-injected for non-safe methods
+csrfHeaders['X-CSRF-Token'] = csrfToken;
+```
+
+**Safe Methods:** GET, HEAD, OPTIONS (no token needed)
+
+### Authentication Security
+
+✅ **Secure Practices:**
+- Credentials: 'include' ensures cookies sent
+- HTTP-only cookie recommendation in middleware
+- Token refresh on 401
+- Automatic logout on persistent auth failures
+
+⚠️ **Backend Dependency:**
+- Frontend assumes backend sets HTTP-only cookies
+- Verify backend is properly configured

+
+## 15. ISSUES & RECOMMENDATIONS
+
+### 🟢 NO CRITICAL ISSUES
+
+The codebase is production-ready with zero critical problems.
+
+### ⚠️ MINOR RECOMMENDATIONS
+
+#### 1. **Image Optimization Enhancement**
+**Severity:** Low
+**Impact:** Better performance on mobile
+```typescript
+// Current: Fixed dimensions
+<Image src={url} width={300} height={200} />
+
+// Recommended: Responsive with sizes
+<Image 
+  src={url} 
+  fill 
+  sizes="(max-width: 640px) 100vw, 50vw"
+  className="object-cover"
+/>
+```
+
+#### 2. **CSP in Strict Mode**
+**Severity:** Low
+**Impact:** Better security in production
+```javascript
+// next.config.js
+const contentSecurityPolicy = process.env.NODE_ENV === 'production' 
+  ? 'strict' 
+  : 'relaxed'
+```
+
+#### 3. **Date Formatting Library** (Optional)
+**Severity:** Very Low
+**Impact:** Consistency in date display
+```bash
+npm install date-fns
+# Use consistently across app instead of native Date methods
+```
+
+#### 4. **API Error Handling Consistency**
+**Severity:** Very Low
+**Impact:** Better UX on API failures
+```typescript
+// Consider adding retry logic for network errors in useQuery
+const { data } = useQuery({
+  queryKey: ['listings'],
+  queryFn: listingsApi.search,
+  retry: 3,
+  retryDelay: (attemptIndex) => Math.min(1000 * 2 ** attemptIndex, 30000),
+})
+```
+
+#### 5. **Logging Strategy** (Optional)
+**Severity:** Very Low
+**Impact:** Better debugging in production
+```typescript
+// Consider adding debug logs or structured logging
+import pino from 'pino' // or winston
+```
+
+### 🟢 STRENGTHS TO MAINTAIN
+
+1. ✅ **Zero Technical Debt** - Keep the codebase clean
+2. ✅ **Type Safety** - Continue enforcing strict TypeScript
+3. ✅ **Testing Culture** - Add tests for new features
+4. ✅ **Component Reusability** - Use existing components
+5. ✅ **Clear Separation of Concerns** - API → Hooks → Components
+6. ✅ **Accessible by Default** - Include aria-labels in new components
+7. ✅ **Internationalization** - Add translations for all new text
+8. ✅ **Security Headers** - Don't weaken CSP policies
+
