# Phase 4.1 Verification — AI Spare Parts Deep Identification (All Waves)
## Current Test
[testing complete]
## Tests
### 1. Spare-Parts Classification Module
expected: |
Classification module in `backend/ai/spare_parts_whitelist.py` correctly identifies:
- Kingston DDR4 RAM as spare part ✓
- 6ft SATA Cable as consumable ✓
- Corsair RM850x PSU as spare part ✓
- Power Cable AC Cord as consumable ✓
- Fuzzy matching works (e.g., "Random Access Memory" → spare part) ✓
result: pass
### 2. AI Prompt Enhancement (Gemini & Claude)
expected: |
Both AI providers (Gemini and Claude) have been updated with spare-parts classification guidance:
- `config/ai_prompt.md` contains "Spare-Parts vs Consumables Classification" section
- Includes decision tree logic with 3-question qualification check
- Provides 8 concrete examples (4 spare parts + 4 consumables)
- JSON output format unchanged
result: pass
### 3. Unit Tests for Classification Module
expected: |
Test file `tests/test_spare_parts_classification.py` contains 25+ test cases:
- Exact match tests (RAM, storage, processors, power supplies)
- Consumable tests (cables, fasteners, thermal materials)
- Fuzzy match tests (RAM variants, storage variants)
- Edge case tests (power cable vs PSU, empty strings, case insensitivity)
- All assertions pass when tests are run
result: pass
### 4. Web Scraper Service
expected: |
Service in `backend/services/web_scraper.py` provides:
- `SearchRateLimiter` class with rate limiting (1 request per 5 seconds)
- `async search_google(query)` function that returns top 5 results
- `async search_bing(query)` function as fallback
- User-Agent rotation (11 different agents)
- Graceful handling of 429/403 blocking
- All async/await patterns correct
result: pass
### 5. Spec Extractor Service
expected: |
Service in `backend/services/spec_extractor.py` provides:
- `ExtractedSpecs` dataclass with 11 fields (manufacturer, model, capacity, etc.)
- `extract_specs_from_search()` function with regex patterns for:
- Memory types (DDR3/4/5), capacity (GB/TB), speed (MHz)
- Storage detection (SSD, HDD, NVMe, M.2)
- Processor extraction (Intel, AMD, NVIDIA)
- Power ratings (850W, 1000W)
- Confidence scoring (0.0-1.0) on all extractions
- Context-aware field mapping to Item model
result: pass
### 6. Search Orchestrator Service
expected: |
Service in `backend/services/spare_parts_search.py` provides:
- `async search_spare_parts()` function that:
- Validates category is a spare part
- Searches Google first, falls back to Bing
- Extracts specs from results
- Returns Dict with {category, type, description, notes, confidence}
- Returns None gracefully on timeout/failure
- Respects timeout parameter (default 30s)
- `async search_multiple_candidates()` for batch search
result: pass
### 7. Backend Integration Tests
expected: |
Test file `tests/test_spare_parts_search.py` contains 20+ test cases covering:
- SearchRateLimiter initialization and acquisition
- SpecExtractor for Memory, Storage, Processor, Power specs
- Field mapping for different item categories
- Search orchestration with fallback
- Timeout handling and graceful degradation
- Non-spare-part rejection
- Batch search with multiple candidates
- All tests pass when run with pytest
result: pass
### 8. useItemSearch Hook
expected: |
Hook in `frontend/hooks/useItemSearch.ts` provides:
- `SearchState` interface with 5 fields (isSearching, searchError, searchResults, searchStatus, retryCount)
- `performSearch(partNumber, category)` function that calls `/api/onboarding/search`
- `retrySearch()` function with max retry limit
- `skipSearch()` function to proceed without search
- Timeout protection (default 30s, configurable)
- Graceful error handling (timeout vs network error)
- TypeScript strict mode compliance
result: pass
### 9. SearchLoadingModal Component
expected: |
Component in `frontend/components/SearchLoadingModal.tsx` provides:
- Modal that displays when `isOpen={true}`
- 30-second countdown timer (configurable)
- Progress bar showing elapsed time
- Non-dismissible modal (blocks user interaction)
- Auto-triggers `onTimeout` callback when countdown expires
- Clean Tailwind styling with primary color progress bar
result: pass
### 10. SearchErrorModal Component
expected: |
Component in `frontend/components/SearchErrorModal.tsx` provides:
- Modal that displays when error occurs
- Shows error message clearly
- "Retry" button to retry the search
- "Skip" button to proceed without search results
- Callback handling for both actions
result: pass
### 11. AIOnboarding Component Integration
expected: |
The AIOnboarding component has been integrated with search:
- Triggers search after AI extraction when spare part is detected
- Shows SearchLoadingModal while search is in progress
- Shows SearchErrorModal if search fails
- Pre-populates extracted fields from search results
- Allows user to retry or skip search
- Merges search results with AI extraction seamlessly
result: pass
### 12. Frontend Component Tests
expected: |
Test files exist and pass:
- `frontend/tests/useItemSearch.test.tsx` (hook tests)
- `frontend/tests/SearchLoadingModal.test.tsx` (modal tests)
- `frontend/tests/SearchErrorModal.test.tsx` (error modal tests)
- All tests use Vitest + React Testing Library
- Tests cover happy path, error cases, and timeout scenarios
result: pass
### 13. End-to-End Frontend-Backend Flow
expected: |
Complete flow works as expected:
1. User scans/uploads item image in AIOnboarding
2. AI extracts item data (category, part number, etc.)
3. If spare part is detected, search is triggered automatically
4. SearchLoadingModal shows 30-second countdown
5. Search results are extracted and pre-populate fields
6. User can edit/confirm the merged data
7. Item is saved with AI + search data
8. On error: SearchErrorModal allows retry or skip
result: pass
### 14. Feature Flags & Configuration
expected: |
Configuration is in place:
- API endpoint `/api/onboarding/search` exists and works
- Search timeout is configurable (default 30s)
- Max retry count is configurable
- Rate limiting is applied (1 request per 5 seconds)
- Graceful degradation when search unavailable
result: pass
