Sprint 10 - Advanced Search & Catalog Report

1. Architecture

• Existing platform architecture was preserved.
• No authentication flow changes.
• No payment flow changes.
• No bootstrap loading flow changes.
• Widget engine and section engine were not modified.
• ProductFacade was only extended (no contract removals or breaking changes).

Data Flow

• Catalog UI calls ProductFacade only.
• ProductFacade extensions for sprint 10:
  • search(criteria)
  • filter(criteria)
  • sort(criteria)
  • loadCatalog(criteria)
• No HttpClient usage in feature layer.

2. New Reusable Components

  • supports multi-select, range, toggle filter types

Sorting Module

5. Backend Expectations

Documented current and future-ready expectations:

• Future-ready:
  • GET /search/suggestions?q={term}
  • GET /catalog/filters?category={id}&q={term}

6. Validation Results

Build

• npm run build: PASS

Architecture

• npm run arch:check:boundaries: PASS
• npm run arch:check:cycles: PASS

Layering checks

• HttpClient in feature layer: none found
• DTO leaks in feature layer: none found (search matched addToCart text only, not DTO usage)

Compatibility

• Widget compatibility preserved
• Section engine compatibility preserved

7. Documentation Updated

• docs/platform/00-bootstrap-example.md
• docs/platform/02-bootstrap-json-spec.md
• docs/platform/06-api-contracts.md

8. Future Extension Points

• Backend-driven suggestions endpoint integration.
• Backend-driven dynamic filter metadata (option counts/ranges/facets).
• Navigation mode implementations:
  • left category navigation
  • mega category layout
  • top category carousel
• URL-state sync for all search/filter/sort/layout inputs.
• Dedicated saved searches / personalized search suggestions.
