# Sprint 11 - User Experience Module Report

## Scope
Implemented reusable customer experience capabilities for marketplace storefront UX while preserving established architecture constraints.

Implemented features:
- Wishlist (guest local storage + architecture-ready repository contract)
- Compare (configurable max count, reusable comparison table, compare page)
- Recently Viewed (auto tracking + reusable strip + widget compatibility)
- Continue Browsing (persist/restore filters, sort, page, scroll)
- Saved Searches (architecture + UI integration)
- Product Sharing (Web Share + clipboard fallback)
- Product Card action preparation without duplication
- Floating notifications and heart animation

## Architectural Constraints Compliance
Confirmed constraints:
- No modifications to authentication, payment, bootstrap loading flow, widget engine core, section engine core.
- No direct HttpClient usage in UI feature components.
- Product data path remains facade-driven.
- Existing ProductFacade contracts preserved (only UX facade added separately).
- Bootstrap contains feature configuration only; no business/user data payload.

## Documentation Updates
Updated to include Sprint 11 bootstrap and backend contract expectations:

- docs/platform/06-api-contracts.md
- docs/platform/13-backend-requirements.md
- docs/backend-platform/business-apis.md

## Validation
Executed:
- npm run build
- npm run arch:check:boundaries
- npm run arch:check:cycles

Results:
- Build: PASS (existing bundle budget warning remains)
- Architecture boundaries: PASS
- Circular dependencies: PASS

## Notes
- Guest mode is fully functional using local storage.
- Authenticated synchronization is prepared by repository contracts and can be implemented via alternate repository provider without changing feature UI components.
- Bootstrap remains configuration-only and contains no user/business lists for wishlist/compare/recently viewed/saved searches.
