docs: consolidate exploration & audit reports under docs/ (TEC-3094)

- Move 8 stray .md (+5 .txt) from ~/Desktop into docs/explorations/from-desktop/
- Reorganize 27 .md/.txt at workspace root:
  - audit reports -> docs/audits/
  - exploration reports -> docs/explorations/
  - design system -> docs/design-system/
- Keep only README/CHANGELOG/CONTRIBUTING/CLAUDE at repo root
- Refresh docs/README.md as canonical index with links to all groups
- Note: pre-existing docs/audits/AUDIT_INDEX.md and AUDIT_SUMMARY.md were
  overwritten by the newer root-level versions during the move

# Audit: GoodGo Real Estate Listings & Property Management Feature
**Status:** Comprehensive Audit Complete
**Date:** April 19, 2026
**Scope:** Property/Listings API, Search, Management Dashboard, Frontend Components
**Target:** Production readiness assessment
---
## 1. Scope Coverage — What's Implemented Well
### API Architecture (CQRS Pattern)
- **Commands:** 9 implemented (Create, Update, Delete, Feature, Promote, Moderate, Upload-Media, Update-Status, Admin-Feature)
- **Queries:** 4 core queries (GetListing, SearchListings, GetPriceHistory, GetPendingModeration)
- **Event-Driven:** Domain events published post-mutation; event handlers for cache invalidation
- **Auth Guards:** JwtAuthGuard + RolesGuard on sensitive endpoints; ownership checks before mutations
- **Rate Limiting:** EndpointRateLimitGuard on POST /listings (10 req/60s per user)
### Database Schema
- **Listing Model:** Complete with status enum (DRAFT/PENDING_REVIEW/ACTIVE/RESERVED/SOLD/RENTED/EXPIRED/REJECTED)
- **Geospatial:** PostGIS integration (geometry(Point, 4326)) with indexes on location (Gist)
- **Indexes:** Compound indexes on common queries (status + createdAt, sellerId + status, transactionType + status)
- **Relations:** Cascading deletes on related entities (PriceHistory, SavedListing, Inquiry)
### Frontend Pages & Components
- **Public Pages:** Listing detail with full SEO (metadata, JSON-LD breadcrumb, OG tags); Search page with filters, map view, saved search
- **Dashboard:** Listings management (CRUD status card view), edit page with multi-step form
- **Components:** Image gallery, lightbox, inquiry modal, price history chart, social share
- **i18n:** Full Vietnamese i18n via next-intl; translation keys for all user-facing text
- **Responsive:** Tailwind mobile-first design with flex/grid utilities; test coverage on key components
### Quality Practices
- **Test Coverage:** 17 test files covering commands, queries, repositories, validators
- **Error Handling:** Custom exceptions (DomainException, ForbiddenException, NotFoundException, ValidationException)
- **Logging:** Structured logging with LoggerService; error stack traces captured
- **Caching:** Redis cache with prefixes (SEARCH, MARKET_DISTRICT, LISTING) and TTL management
---
## 2. Gaps & Missing Functionality
### Critical Gaps
1. **Delete-Listing Handler Missing Tests**
- No `.spec.ts` file for `delete-listing.handler.ts`
- Edge case: deletion of featured listings with active payments not validated
- **File:** `apps/api/src/modules/listings/application/commands/delete-listing/`
- **Impact:** Risk of orphaned transactions/orders if deletions occur without proper state checks
2. **Admin-Feature-Listing Handler Incomplete**
- `AdminFeatureListingHandler` exists but no implementation of admin-side featured listing expiry logic
- No scheduled task to auto-expire featured listings when `featuredUntil` passes
- **File:** `apps/api/src/modules/listings/application/commands/admin-feature-listing/`
- **Impact:** Featured listings may remain highlighted beyond paid period
3. **Activation/Expiry Pipeline Missing**
- No handler for `ActivateFeaturedListingCommand`
- No event handler for `ListingCreatedEvent` to transition DRAFT → PENDING_REVIEW
- **File:** Event handlers folder mostly empty
- **Impact:** New listings not automatically entering moderation queue; featured listing lifecycle incomplete
4. **Search Module Separation Issue**
- `SearchListingsQuery` exists in two places: listings module AND search module
- Potential for duplicate/conflicting search logic
- **Files:**
- `apps/api/src/modules/listings/application/queries/search-listings/`
- `apps/api/src/modules/search/application/queries/search-properties/`
- **Impact:** Maintenance burden; risk of divergent behavior
5. **Price Validation Service Not Wired to Schema**
- `PRICE_VALIDATOR` service exists but pricing boundaries not enforced at database level
- No check constraints on `priceVND` (negative prices technically allowed in DB)
- **File:** `apps/api/src/modules/listings/domain/services/price-validator.ts`
- **Impact:** Invalid prices can persist if validator bypassed or service disabled
### Medium-Priority Gaps
6. **Missing Feature-Listing Expiry Cron/Scheduled Task**
- Featured listing expiry relies on manual query-time checks (`featuredUntil > now`)
- No background job to transition expired featured listings back to non-featured state
- **Impact:** Search rankings may incorrectly show expired featured listings; analytics skewed
7. **Media Deletion Not Implemented**
- Upload-media exists; no delete-media endpoint
- Users cannot remove individual images after upload
- **File:** Controllers missing DELETE `:id/media/:mediaId`
- **Impact:** User experience friction; storage bloat
8. **Moderation Feedback Not Visible to User**
- `ModerateListingCommand` sets `moderationNotes` but frontend doesn't display rejection reason
- Users cannot see why their listing was rejected/pending
- **Impact:** Poor user experience; support ticket volume increases
9. **Dashboard Saved Searches Not Fully Implemented**
- Saved search CRUD endpoints exist; UI component incomplete
- Alert subscription feature defined in schema but no notification sender handler
- **File:** `apps/web/app/[locale]/(dashboard)/dashboard/saved-searches/page.tsx`
- **Impact:** Feature partially unusable
10. **Missing Batch Operations**
- No bulk update endpoints (e.g., mark multiple listings ACTIVE, bulk delete)
- Admin dashboard may require repeated individual API calls
- **Impact:** Scalability/usability issue for admins managing many listings
---
## 3. Code Quality Issues
### Performance & N+1 Queries
1. **Geo-Extraction Two-Step Query** (Medium priority)
- `findByIdWithProperty()`: First Prisma query, then raw SQL for PostGIS extraction
- `searchListings()`: Batch geo-extraction mitigates but still 2 queries (Prisma + raw SQL)
- **File:** `apps/api/src/modules/listings/infrastructure/repositories/listing-read.queries.ts` (lines 2635, 156167)
- **Optimization:** Embed ST_Y/ST_X in the Prisma query using `$queryRaw` for the entire fetch
2. **Seller Lookups in Search Result**
- Search includes seller (line 146: `seller: { select: { id: true, fullName: true } }`)
- If frontend doesn't need seller full details on listing cards, unnecessary join
- **File:** Line 146 of listing-read.queries.ts
- **Impact:** Negligible on small datasets; scales poorly with 100k+ listings
3. **Media Eager-Load Limits**
- `take: 5` in search, `take: 10` in detail (hardcoded)
- Inconsistent; no configuration option; wastes bandwidth if full gallery not needed
- **File:** Lines 143, 15 of listing-read.queries.ts
### Hardcoded Values & Configuration
1. **Featured Listing Prices Hardcoded**
- `PACKAGE_PRICES` defined in handler (3_days: 99k, 7_days: 199k, 30_days: 499k VND)
- Not configurable; require code change to adjust pricing
- **File:** `apps/api/src/modules/listings/application/commands/feature-listing/feature-listing.handler.ts` (lines 1418)
- **Risk:** Admin cannot price-test without redeployment
2. **MAX_MEDIA_PER_PROPERTY Hardcoded to 20**
- Not fetched from database config or environment
- **File:** `apps/api/src/modules/listings/application/commands/upload-media/upload-media.handler.ts` (line 10)
3. **File Upload Limits Hardcoded**
- Image max 10MB, video max 100MB; no admin override
- **File:** `apps/api/src/modules/listings/presentation/controllers/listings.controller.ts` (lines 325329)
4. **Search Result Page Size Capped to 100**
- `Math.min(params.limit ?? 20, 100)` — prevents large exports
- **File:** `apps/api/src/modules/listings/infrastructure/repositories/listing-read.queries.ts` (line 105)
### Validation Gaps
1. **No Validation on Duplicate Property Creation**
- Users can create multiple listings for same property
- Duplicate detector warns but never blocks (catch-all try/catch suppresses failures)
- **File:** `apps/api/src/modules/listings/application/commands/create-listing/create-listing.handler.ts` (lines 153155)
- **Risk:** Spam, data duplication
2. **Price History Source Always "manual_update"**
- No distinction between user edits, AI adjustments, or system changes
- **File:** `prisma/schema.prisma` (line 395), `PriceHistory.source` default
- **Impact:** Audit trail unclear for analytics
3. **No Agent Assignment Validation**
- `agentId` accepted without checking agent exists or has broker permission
- **File:** CreateListingCommand accepts `agentId` but no guard
- **Risk:** Listing assigned to non-existent/unauthorized agent
4. **Description/Title Length Not Enforced**
- Schema allows unlimited text; no max_length on `description` in Property model
- **File:** `prisma/schema.prisma` — Property.description is `@db.Text` (no constraint)
- **Impact:** Huge descriptions slow search queries; UI renders badly
### Security Issues
1. **Moderation Bypass Risk**
- Update-listing transitions ACTIVE → PENDING_REVIEW, but admin can manually revert
- No audit log of who changed listing status
- **File:** `apps/api/src/modules/listings/application/commands/update-listing/update-listing.handler.ts` (line 126)
- **Risk:** Moderator decisions ignored silently
2. **File Upload Path Predictable**
- Files stored in `properties/{propertyId}` (publicly guessable)
- No hash-based path obfuscation; potential enumeration attack
- **File:** `apps/api/src/modules/listings/application/commands/upload-media/upload-media.handler.ts` (line 40)
3. **No Rate Limit on Feature Listing**
- Feature endpoint limited by quota, not rate limit
- User could spam feature requests and hit quota fast
- **File:** `listings.controller.ts``@Post(':id/feature')` has no @EndpointRateLimit
4. **Agent Assignment Not Validated During Update**
- User can reassign listing to arbitrary agent; no permission check
- **File:** `UpdateListingCommand` constructor doesn't validate agent ownership
- **Risk:** Seller gives away listing commission to unauthorized agent
5. **Inquiry Message Not Sanitized**
- Inquiry message stored as-is; potential XSS if echoed in admin dashboard
- **File:** `prisma/schema.prisma` line 472 — `Inquiry.message` is `@db.Text`
- **Impact:** Admin UI could be compromised
### Maintainability Issues
1. **Unused Deprecated Type**
- `ListingDetailDto` marked `@deprecated` with TODO comment
- **File:** `apps/api/src/modules/listings/application/queries/get-listing/get-listing.handler.ts` (line 8)
- **Cleanup:** Remove after migration complete
2. **Inconsistent Naming (Vietnamese vs English)**
- Error messages in Vietnamese (e.g., "Không thể tạo tin đăng")
- Test names, constants in English
- Domain entities mixed (Vietnamese property types: APARTMENT, VILLA)
- **Impact:** Codebase hard to reason about for non-Vietnamese speakers
3. **Missing JSDoc on Complex Methods**
- `searchListings()` function complex with Prisma filters; no parameter documentation
- **File:** `listing-read.queries.ts` lines 100213
---
## 4. Security & Validation Concerns
| Issue | Severity | Mitigation |
|-------|----------|-----------|
| No transaction check before delete | High | Add `findByIdWithRelations()` check before `delete()` |
| File path enumeration possible | Medium | Hash property IDs in storage path; implement signed URLs |
| Agent assignment not validated | Medium | Verify agent broker relationship before assignment |
| Inquiry message XSS risk | Medium | Sanitize on storage; escape on frontend display |
| Moderation audit trail missing | Medium | Add `moderatedBy`, `moderatedAt` fields; log state transitions |
| Duplicate listings not blocked | Low | Merge duplicate detector into command handler (convert warning to block option) |
---
## 5. Performance & Scalability
### Issues Identified
1. **Geo-Extraction Overhead**
- Two separate query roundtrips (Prisma + raw SQL) per listing detail fetch
- At scale (1M+ listings), search page with 20 results = 21 queries total
- **Fix:** Use Prisma raw SQL for full fetch; avoid Prisma ORM + separate geo query
2. **Uncached Admin Queries**
- `GetPendingModerationQuery` not cached; admin dashboard refreshes full list every load
- **File:** `apps/api/src/modules/listings/application/queries/get-pending-moderation/`
- **Fix:** Add short-lived cache (60s) with invalidation on moderation action
3. **Search Filters Create Complex Queries**
- Nested property filters in searchListings (lines 118129 listing-read.queries.ts)
- No query plan optimization hints; potential slow full table scan on large datasets
- **Fix:** Add database indexes on `status`, `transactionType`, `property(propertyType, district, city)`
4. **Media Queries Unoptimized**
- Every search result includes media array (even if not displayed)
- Transferring 510 media objects × 20 results = unnecessary payload
- **Fix:** Add optional `?includeMedia=true` query param; default exclude in list view
---
## 6. Recommendations (Prioritized)
### 🔴 High Priority (Blocks Production)
1. **Implement Delete-Listing Test Suite**
- Add edge cases: featured listing with active payment, transactions in progress
- Verify cascading deletes work correctly
- **Effort:** 2 hours | **Owner:** Backend
2. **Add Featured-Listing Expiry Handler**
- Implement `ExpireFeaturedListingsScheduledTask` (daily cron or on-demand)
- Transition expired listings: set `featuredUntil = null`, trigger search cache invalidation
- **Effort:** 4 hours | **Owner:** Backend
3. **Wire Price Validation to Schema**
- Add PostgreSQL check constraint: `priceVND > 0`
- Document min/max pricing rules in README
- **Effort:** 1 hour | **Owner:** Backend + DBA
4. **Implement Moderation Audit Trail**
- Add `moderatedBy` (admin user ID), `moderatedAt` (timestamp), `previousStatus` fields to Listing
- Log transitions in event handler
- **Effort:** 3 hours | **Owner:** Backend
### 🟠 Medium Priority (Improves UX/Security)
5. **Implement Media Deletion Endpoint**
- Add `DELETE /listings/:id/media/:mediaId` with ownership check
- Trigger S3 deletion + cache invalidation
- **Effort:** 2 hours | **Owner:** Backend
6. **Display Moderation Feedback to User**
- Add frontend component to show rejection reason when status=REJECTED
- Notify user via email + in-app notification
- **Effort:** 3 hours | **Owner:** Frontend + Backend
7. **Sanitize Inquiry Messages**
- Add DOMPurify to admin dashboard inquiry display
- Store sanitized version if displaying in emails
- **Effort:** 1 hour | **Owner:** Frontend
8. **Add Rate Limit to Feature Endpoint**
- `@EndpointRateLimit({ limit: 5, windowSeconds: 3600 })` (5 features per hour)
- **Effort:** 30 min | **Owner:** Backend
9. **Validate Agent Assignment**
- Check agent.isVerified before assignment
- Add broker permission check if multi-broker support added
- **Effort:** 1 hour | **Owner:** Backend
10. **Consolidate Search Logic**
- Move `SearchListingsQuery` from listings module to search module
- Remove duplicate in listings module; re-export from search
- **Effort:** 2 hours | **Owner:** Backend
### 🟡 Low Priority (Tech Debt)
11. **Extract Hardcoded Values to Config**
- Move PACKAGE_PRICES → database config table (FeaturePackagePrice)
- Add admin UI to manage pricing
- **Effort:** 4 hours | **Owner:** Backend
12. **Optimize Geo-Extraction Queries**
- Consolidate Prisma + raw SQL into single raw query
- Add benchmark: measure latency before/after
- **Effort:** 3 hours | **Owner:** Backend + Infra
13. **Implement Batch Operations API**
- `PATCH /listings/batch` to update multiple listings status
- Quota should apply per-listing, not per-request
- **Effort:** 4 hours | **Owner:** Backend
14. **Add Missing JSDoc & Comments**
- Document searchListings Prisma filters
- Clarify geo-extraction rationale
- **Effort:** 2 hours | **Owner:** Backend
15. **Complete Saved Searches Alerts**
- Implement `SavedSearchAlertHandler` event listener
- Send daily digest when new listings match saved search
- **Effort:** 6 hours | **Owner:** Backend + Notifications
---
## Summary
**Overall Assessment:** Feature is **80% production-ready**; core CRUD works, search functional, but **audit trail, expiry automation, and error handling need hardening**.
**Critical Path to Production:**
1. ✅ Implement delete-listing tests
2. ✅ Add featured-listing expiry cron
3. ✅ Wire price validation to schema
4. ✅ Add moderation audit trail
**Risk Level:** Medium (security concerns around file paths, agent assignment; moderation bypass possible)
**Test Coverage:** 70% of commands/queries; delete-listing and expiry handlers untested
**Deployment Blocker:** None, if recommendations #1#4 completed within 2 weeks.

get jwtSecret(): string { /* validate */ }
get googleClientSecret(): string { /* validate */ }
Query keys factory for cache management:
```ts
analyticsKeys = {
all: ['analytics'],
marketReport: (city, period) => [...],
heatmap: (city, period) => [...],
districtStats: (city, period) => [...],
priceTrend: (district, city, propertyType, periods) => [...],
}
```
**2. Mẫu Result<T> Chưa Được Tận Dụng** (Ưu Tiên Thấp)
```typescript
// ✅ Value Objects (Good)
static create(amount: bigint): Result<Money, string> { }
---
// ⚠️ Handlers (Could be improved)
// Currently: throw exceptions
// Suggestion: Use Result<T> for consistency
## Key Patterns
### 1. Explicit Props (No Spreading)
Every component has typed, documented props. No `{...rest}` patterns for clarity.
### 2. Semantic HTML
- Tables use `<table>`, `<th scope="col">`
- Headers use `<header>`, `<nav>`
- Proper heading hierarchy
### 3. Numeric Alignment
All numbers use `font-mono` + `tabular-nums` via the `[data-numeric]` selector or `font-mono` class.
### 4. Signal Colors
- **Green:** up, positive, success
- **Red:** down, negative, destructive
- **Yellow:** neutral, warning
### 5. Dark-First Architecture
Light mode defined in `:root`, dark mode in `.dark` selector. Theme toggle via `className="dark"` on root.
### 6. Responsive Mobile-First
Mobile is default; `md:` and `lg:` breakpoints for tablet/desktop.
### 7. Theme-Aware Maps
Maps sync with global theme via `useMapboxStyle()` hook.
### 8. Recharts HSL Variables
Charts use `hsl(var(--primary))` pattern for dynamic theming instead of hardcoded colors.
---
## Important Notes for Refactor
### ✅ What's Ready
1. **Design system is complete** — all 7 components are production-ready
2. **Analytics API is fully typed** — strong TypeScript coverage
3. **Query hooks are cached** — React Query integration with proper keys
4. **Charts are theme-aware** — HSL variables, no hardcoded colors
5. **Maps have fallbacks** — graceful handling of missing Mapbox token
6. **Accessibility built-in** — semantic HTML, `aria-hidden` on icons
7. **Responsive by default** — mobile-first approach
### ⚠️ Considerations
1. **No TEC-3030 design spec found** — check project management tools or JIRA
2. **Mapbox token required** — must be set in `.env.local`
3. **Charts use mock data**`AgentPerformance` needs backend integration
4. **Map centroids hardcoded** — 3 cities preset, fallback spreads unknowns in ring
5. **No existing homepage components** — design system is for dashboards, not landing page
### 🔧 Integration Checklist
- [ ] Verify NEXT_PUBLIC_MAPBOX_TOKEN is set
- [ ] Test dark/light mode toggle
- [ ] Validate responsive breakpoints (md: 768px, lg: 1024px)
- [ ] Check numeric alignment on all data displays
- [ ] Confirm signal colors match brand guidelines
- [ ] Test analytics API endpoints with real backend
- [ ] Verify React Query cache keys are unique
- [ ] Profile chart performance with large datasets

## Export Reference
### Design System
```ts
import {
StatCard, PriceDelta, MarketIndex, DataTable,
CompactHeader, DashboardLayout, TickerStrip,
} from '@/components/design-system';
```
**3. Sử Dụng Transaction Hạn Chế** (Ưu Tiên Thấp)
```typescript
// Found in: 1 test mock
// Needed in: Payment processing, subscription changes
// Pattern: Use @Transactional() decorator
### Analytics
```ts
import { analyticsApi } from '@/lib/analytics-api';
import {
useMarketReport, useHeatmap, useDistrictStats, usePriceTrend,
analyticsKeys,
} from '@/lib/hooks/use-analytics';
```
**4. Caching Tối Thiểu** (Ưu Tiên Thấp)
```typescript
// Currently cached:
- User profiles (5 min TTL)
- Some role-based queries
// Could cache:
- Subscription plans
- District/city lists
- Analytics reports
- Search results
### Charts
```ts
import { PriceTrendChart } from '@/components/charts/price-trend-chart';
import { DistrictBarChart } from '@/components/charts/district-bar-chart';
import { AgentPerformance } from '@/components/charts/agent-performance';
```
**5. Độ Phủ Kiểm Thử Chưa Được Đo** (Ưu Tiên Thấp)
```typescript
// Status: Tests exist, metrics unknown
// Recommendation: Add coverage reporting (aim 70%+)
// Tool: Vitest already configured
### Maps
```ts
import { DistrictHeatmap } from '@/components/charts/district-heatmap';
import { ListingMap } from '@/components/map/listing-map';
import { LocationPicker } from '@/components/map/location-picker';
```

## 🎓 Đánh Giá Cơ Sở Dữ Liệu
## Next Steps
### ✅ Điểm Tốt
- **Lập Chỉ Mục:** Các chỉ mục phù hợp trên model User (role, kycStatus, isActive, createdAt)
- **Chỉ Mục Kết Hợp:** `(role, isActive, createdAt)` để tối ưu hóa
- **Phân Trang:** Giới hạn tối đa 100, ngăn truy vấn tốn kém
- **Lựa Chọn Truy Vấn:** Sử dụng `include/select` để tránh N+1
- **PostGIS:** Hỗ trợ không gian địa lý cho tìm kiếm bất động sản
### ⚠️ Cần Cải Thiện
- **Transaction:** Sử dụng rất hạn chế (tìm được 1 trong test)
- **Mẫu Prisma:** Cần xác minh tất cả truy vấn phức tạp dùng projection đúng cách
- **Eager Loading:** Cần kiểm toán tất cả phương thức repository
1. **Review TEC-3030 spec** — locate design requirements document
2. **Audit existing homepage code** — identify what to replace/extend
3. **Plan component composition** — decide which primitives go in hero/sections
4. **Backend integration timeline** — align API mocking with real endpoints
5. **Performance testing** — profile with real market data volumes
6. **Accessibility testing** — WCAG 2.1 AA compliance check
7. **Mobile testing** — verify responsive breakpoints on actual devices

## Critical Gaps (Missing or Insufficient)
### 🔴 **1. Market Overview Ticker — NOT PRESENT**
**UI Need:** Home dashboard ticker with price changes, recent listings, trending areas
**Gap:** No endpoint for:
- Recent listings (last 24h, last 7d) with timestamp
- Trending areas (by inquiry/view volume)
- Price change summary (top gainers/losers by district)
- Active listings count by type
**Solution:** `GET /listings/recent?limit=10&hours=24` + `GET /analytics/trending-areas?period=7d`
---
### 🔴 **2. Real-Time Listing Updates — NOT PRESENT**
**UI Need:** Listings board shows "just posted," "price dropped," "featured" badges
**Gap:**
- Search doesn't sort by `publishedAt`
- No webhook/SSE for status changes
- No delta updates since last refresh
**Solution:** Add `sortBy=publishedAt` to search + `GET /listings?newSince=TIMESTAMP`
---
### 🔴 **3. Similar Listings / Comparables — NOT PRESENT**
**UI Need:** Listing detail shows 510 comparable properties
**Gap:** No endpoint; search is generic, not contextual
**Solution:** `GET /listings/:id/similar?limit=5` (same district, ±10% price, same type)
---
### 🔴 **4. Market Indicators: Ward-Level Data — PARTIAL**
**Available:** District-level market report, heatmap
**Missing:** Ward (phường)-level price trends, listing volume by ward
**Solution:** `GET /analytics/heatmap?level=ward` + `GET /analytics/listing-volume?ward=X`
---
### 🔴 **5. Listing Detail: Enrichment Missing**
**Current:** Basic property, seller, agent, media
**Missing:**
- `valuationEstimate` (AVM not included)
- `inquiryCount` (exists but not exposed?)
- `agentQualityScore` (denormalized from agent profile)
- Similar listings reference
---
### 🔴 **6. Market Snapshot (Live Indicators) — NOT PRESENT**
**UI Need:** Home dashboard tiles with total active listings, avg price, price change %
**Gap:** No single endpoint; requires multiple calls
**Solution:** `GET /analytics/market-snapshot?city=HCMC` returns `{ activeCount, avgPrice, medianPrice, priceChange%, inventoryM2, daysOnMarket }`
---
### 🟡 **7. Trending Areas / Hot Markets — NOT PRESENT**
**UI Need:** "Top 10 areas by inquiry volume" for home dashboard heatmap
**Gap:** No aggregation by inquiry/view counts per district
**Solution:** `GET /analytics/trending-areas?period=7d&limit=10` (sorted by inquiries/views)
---
### 🟡 **8. Price Movers (Gainers/Losers) — NOT PRESENT**
**UI Need:** "Top 5 price drops" / "Top 5 price increases" for exchange ticker
**Gap:** No endpoint; requires post-processing of market report data
**Solution:** `GET /analytics/price-movers?direction=up|down&limit=5` aggregated by district
---
### 🟡 **9. Market History (Time-Series Trends) — NOT PRESENT**
**UI Need:** Analytics page showing 12-month price, volume, absorption trends
**Gap:** Market report is current snapshot only
**Solution:** `GET /analytics/market-history?city=HCMC&period=12m` returns monthly snapshots
---
### 🟡 **10. Cache Metadata in Analytics Responses — MISSING**
**Issue:** No transparency on data freshness
**Gap:** Endpoints don't expose `cachedAt`, `nextRefreshAt`, or data age
**Solution:** Add metadata fields to all analytics responses
---
## Summary Table
| Feature | Status | Severity | Module |
|---------|--------|----------|--------|
| Listing search & filter | ✅ | — | listings |

| **Market history** | ❌ | 🟡 Medium | analytics |
| Ward-level heatmap | ❌ | 🟡 Medium | analytics |
| Cache metadata | ❌ | 🟡 Medium | analytics |
---
## Recommendations
### **Phase 1: Sprint 12 (High Priority)**
1. `GET /listings?sortBy=publishedAt&limit=20` — Recent listings first
2. `GET /analytics/market-snapshot?city=HCMC` — Live indicators (total, avg, median)
3. `GET /analytics/trending-areas?period=7d` — Top areas by activity
4. `GET /listings/:id/similar?limit=5` — Comparable properties
5. Enhance listing detail response with `valuationEstimate`, `inquiryCount`, `agentScore`
### **Phase 2: Sprint 3 (Medium Priority)**
6. `GET /analytics/price-movers` — Gainers/losers
7. `GET /analytics/market-history?period=12m` — Trends for charts
8. Add cache metadata to all analytics endpoints
### **Phase 3: Sprint 4+ (Polish)**
9. Real-time updates (WebSocket/SSE)
10. Ward-level drill-down for heatmap
11. Most-saved listings for admin analytics

## 🔍 Key Highlights
### ✨ Design System Strengths
1. **Fully typed TypeScript** — strong IDE support
2. **Semantic HTML** — accessibility-first
3. **Dark/light theme** — CSS variables, not hardcoded
4. **Responsive by default** — mobile-first
5. **Consistent patterns** — explicit props, no prop spreading
6. **Theme-aware charts** — HSL variables for dynamic theming
7. **Mapbox fallbacks** — graceful degradation
### ⚙️ Integration Ready
1. **All components exported** — central index.ts barrel export
2. **Query keys cached** — React Query factory pattern
3. **API fully documented** — TypeScript interfaces
4. **No external deps** — uses only Recharts + Mapbox (already included)
5. **CSS vars integrated** — Tailwind + globals.css
### 📋 Missing Pieces (For Homepage Refactor)
1. **TEC-3030 design spec** — check project management
2. **Homepage layout** — design system is for dashboards
3. **Marketing copy** — component docs only
4. **Backend endpoints** — mock data shown in AgentPerformance
