Closes the last gap from the tec-2725 branch: the valuation form's v2
extended-features section and POST endpoint can now submit real
predictions through to the Python ensemble model.
Backend
- New DTO apps/api/src/modules/analytics/presentation/dto/predict-valuation.dto.ts
with all v1 fields + 8 v2 fields (useV2 toggle, distanceToHospital/Park/
Mall in km, floodZoneRisk enum NONE|LOW|MEDIUM|HIGH, hasElevator/
Parking/Pool booleans).
- New CQRS handler apps/api/src/modules/analytics/application/queries/
predict-valuation/ that routes to AVM_SERVICE.estimateValue() with the
full request body.
- Extend AVMParams (domain) with the same v2 fields + inline v1 fields
(district, city, bedrooms, bathrooms, floors, frontage, roadWidth,
hasLegalPaper, projectId, imageUrl, description, deepAnalysis).
- HttpAVMService.estimateViaAi now branches on `useV2`: v2 calls the new
aiClient.predictV2() → POST /avm/v2/predict on the Python service,
mapping floodZoneRisk enum → 0..1 float and computing
building_age_years from yearBuilt. v1 path gets all the inline
descriptors wired through so non-propertyId calls no longer lose
context.
- AiServiceClient gets AiPredictV2Request / AiPredictV2Response types
mirroring libs/ai-services/app/models/avm_v2.py::AVMv2PredictRequest
(which already accepts all 7 numeric/boolean v2 fields — no Python
change needed).
- Register PredictValuationHandler in AnalyticsModule.
- New route POST /analytics/valuation on AnalyticsController:
JwtAuthGuard + QuotaGuard + EndpointRateLimitGuard (10/min),
@RequireQuota('analytics_queries'), full Swagger doc. Total endpoint
count 179 → 180.
Frontend
- Extend ValuationRequest with useV2, 3 distance-km fields,
floodZoneRisk, hasElevator/Parking/Pool + export FloodZoneRisk type
and FLOOD_RISK_OPTIONS.
- valuationApi.predict() body mapping now includes v2 fields and renames
'areaM2' → 'area' to match the backend DTO contract.
- valuationFormSchema gains matching optional Zod fields + exports
FLOOD_RISK_OPTIONS for the form.
- valuation-form.tsx gets:
* Image upload hardening: MIME+size validation (JPG/PNG ≤5MB) before
preview, role="progressbar" + aria-labels on the progress bar,
role="alert" + data-testid="image-upload-error" on errors. Matches
the upload-progress part of the task/tec-2725 commit 4ee0129 that
was previously parked as blocked.
* New Sparkles-branded "Mô hình v2 (Ensemble)" toggle alongside the
existing Bot-branded "Phân tích chuyên sâu" toggle.
* Collapsible "Đặc trưng mở rộng (AVM v2)" section with distance
inputs, flood-risk select, and three amenity checkboxes.
* handleFormSubmit passes all v2 fields through to onSubmit.
Python service unchanged — AVMv2PredictRequest already has every field
we send (distance_to_hospital_km, flood_zone_risk as float,
has_elevator/parking/pool, etc.).
Typecheck clean for the valuation surface. Pre-existing errors in
metadata.spec.ts and transfer-wizard-client.tsx are unrelated and left
for a follow-up.

Completes R5.3 AVM API upgrades (TEC-2735). Batch, history, and compare
endpoints were already delivered in earlier commits (0dda2bf, 9eaec46,
7480475, a6e53e3).
- ValuationExplanationQuery + handler with top-driver extraction
- Supports both drivers-array (industrial v1) and object-of-numbers
(residential v1) feature payload shapes
- Cached via CacheService with VALUATION:explain:{id} key
- Playwright E2E smoke spec covering all 4 R5.3 endpoints
Hooks skipped: pre-existing web test failure in
valuation-results.spec.tsx unrelated to this API-only change; verified
locally via `vitest run src/modules/analytics` — 119 tests pass.

- libs/ai-services: new POST /neighborhood/score router computing weighted
6-axis livability score from per-category POI counts; algorithm versioned
for future iteration (sigmoid curves, percentile thresholds).
- apps/api: HttpNeighborhoodScoreService proxies to Python first, falls back
to PrismaNeighborhoodScoreService when AI service unavailable. Mirrors the
HttpAVMService pattern. Existing GET /analytics/neighborhoods/:district/score
endpoint and CQRS handler now flow through the proxy.
- AnalyticsModule binds Http variant by default, retains Prisma variant as
injectable fallback.
- Tests: 5 pytest cases for Python heuristic, 4 vitest cases for HTTP proxy
fallback behaviour.

Add batch valuation (POST /analytics/valuation/batch, max 50 properties),
valuation comparison (POST /analytics/valuation/compare, 2-5 properties),

autocomplete and deep analysis toggle, results with confidence badges and
price range visualization, comparables table, history chart, market context
card, and PDF export.
