+# Sprint 9 - Product Engagement Report
+
+## 1. Architecture Decisions
+- Product engagement was implemented as a dedicated module under product feature: `src/app/features/website/product/engagement/components`.
+- ProductFacade remained the single feature entry point for engagement flows:
+  - `loadRating(productID)`
+  - `loadReviews(productID, query)`
+  - `loadQuestions(productID, query)`
+  - `submitReview(productID, input)`
+  - `submitQuestion(productID, input)`
+- No feature component uses `HttpClient` directly.
+- Data flow remains layered:
+  - Feature Container/Components -> `ProductFacade` -> `ProductDataService` -> `ProductDataProvider` (`ApiProductDataProvider`) -> `ApiService`.
+- Existing auth/payment/bootstrap initialization flows were not changed.
+- Widget/section/bootstrap runtime architecture was preserved.
+
+## 2. Reusable Components Added
+### Product Engagement Atoms
+- `StarsComponent`
+- `StarSelectorComponent`
+- `ProductTabsComponent`
+- `RatingSummaryComponent`
+
+### Reviews
+- `ReviewFormComponent`
+- `ReviewCardComponent`
+- `ReviewListComponent` (includes pagination support)
+
+### Questions
+- `QuestionFormComponent`
+- `QuestionCardComponent`
+- `QuestionListComponent` (includes pagination + Ask Question toggle)
+
+### Product Page Sections
+- Existing reusable sections kept:
+  - Gallery, Product Info, Variant Selector, Delivery, Description, Related Products
+- New/updated reusable sections:
+  - `ProductSpecificationsComponent`
+  - `ProductWarrantyComponent`
+  - Reviews section via `ReviewListComponent`
+  - Questions section via `QuestionListComponent`
+
+## 3. Domain Models Added
+File: `src/app/core/products/models/product-engagement.model.ts`
+- `RatingSummary`
+- `Review`
+- `Question`
+- `Answer`
+- Supporting contracts:
+  - `RatingDistributionEntry`
+  - `EngagementListQuery`
+  - `EngagementListResult<T>`
+  - `SubmitReviewInput`
+  - `SubmitQuestionInput`
+
+## 4. Bootstrap Additions (Feature Config Only)
+Added new optional config model:
+- `src/app/shared/models/config/product-page-config.model.ts`
+
+Added to bootstrap contract:
+- `BootstrapConfig.productPage?: ProductPageConfig`
+
+Added to mock bootstrap example:
+- `src/assets/mock/bootstrap/bootstrap.json` now contains `productPage` with:
+  - `rating.enabled`
+  - `reviews.enabled/pageSize/showSummary`
+  - `questions.enabled/pageSize`
+  - `tabs.enabled/items`
+  - `relatedProducts.enabled`
+
+No review/question domain data was placed in bootstrap.
+
+## 5. Backend Endpoints Expected
+Prepared in docs/contracts as target backend API:
+- `GET /products/{id}/rating`
+- `GET /products/{id}/reviews`
+- `GET /products/{id}/questions`
+- `POST /products/{id}/reviews`
+- `POST /products/{id}/questions`
+
+Current runtime uses existing available mock/API item data mapping where applicable, while facade methods and contracts are already prepared for dedicated engagement endpoints.
+
+## 6. Validation Results
+### Build
+- `npm run build` -> PASS
+
+### Architecture Rules
+- No `HttpClient` usage found in feature layer (`src/app/features/**`).
+- No `environment.*` usage found in feature layer (`src/app/features/**`).
+- No DTO imports found in feature layer (`src/app/features/**`, checked for `\bdto\b|\.dto`).
+
+### Architecture Governance Scripts
+- `npm run arch:check:boundaries` -> PASS
+- `npm run arch:check:cycles` -> PASS (`No circular dependency found`)
+
+## 7. Documentation Updated
+Platform docs:
+- `docs/platform/00-bootstrap-example.md`
+- `docs/platform/02-bootstrap-json-spec.md`
+- `docs/platform/06-api-contracts.md`
+- `docs/platform/10-product-domain.md`
+- `docs/platform/13-backend-requirements.md`
+
+Backend docs:
+- `docs/backend-platform/business-apis.md`
+
+## 8. Future Extension Points
+- Photo upload support in review form (placeholder is already present in UI).
+- Backend-side moderation and verification flags for reviews/questions.
+- Dedicated seller identity and accepted-answer workflow integration.
+- Server-driven sorting/filtering for reviews and questions.
+- Optional widgetized engagement blocks for dynamic page composition.
