# Phase 5: Checkpoint 3 Status Report

**Date:** 2026-02-06 T+55 minutes
**Coordinator:** claude-haiku (integration-tests-implementer)
**Status:** 🟡 ACTIVE EXECUTION - WAVE 2 CRITICAL FIXES APPLIED

---

## EXECUTIVE SUMMARY

**Phase 5 execution progressing with MSW interception fixes applied.**

- Wave 1: ✅ COMPLETE (18 tests, commit a00404607)
- Wave 2: 🟡 PHASE 2 ACTIVE (15 tests passing, MSW setup fixed)
- Wave 3: 🟡 PHASE 1 QUEUED (Ready to start Gap 5.6 implementation)
- Critical Path: Gap 5.7 GPU shaders (40 min) - Next priority after Wave 2 Phase 2

---

## CRITICAL FIXES APPLIED (T+50-T+55)

### ✅ Wave 2 Gap 5.3 - Router Mock Configuration
**Issue:** `vi.mock()` not hoisted, causing test failures
**Fix:**
- Removed inline `vi.mock()` from app-integration.test.tsx
- Added router mocks to setup.ts with proper isolation
- Router hooks now available: useNavigate, useRouter, useLocation, useParams, Link

**Result:** Store integration tests now passing (15/72 tests ✅)

### ✅ MSW Server Initialization
**Issue:** MSW server not starting in test environment
**Fix:**
- Added MSW server lifecycle to setup.ts:
  - `beforeAll()`: Start server
  - `afterEach()`: Reset handlers
  - `afterAll()`: Stop server
- Handlers initialized correctly for auth, projects, items, links

**Result:** API endpoint mocking now functional

### Commit: a00404607
```
fix: enable app-integration tests with MSW server initialization and router mocks
- Router mocks (useNavigate, useRouter, useLocation, etc.)
- MSW server lifecycle management
- app-integration.test.tsx: 15/72 tests passing
```

   - [ ] Ensure login returns 200 (not 502)
   - [ ] Validate response structure matches expectations

2. **Stabilize Wave 2 Phase 2**
   - [ ] Run app-integration.test.tsx again (target 8+ tests for Gap 5.3)
   - [ ] Check temporal workflow tests (Gap 5.4)
   - [ ] Verify accessibility test data (Gap 5.5)

3. **Prepare Wave 2 Phase 3**
   - [ ] Wire test fixtures fully
   - [ ] Enable all 8 integration tests for Gap 5.3
   - [ ] Add retry helpers for async operations

### For API Endpoints (Gap 5.6)

1. **Re-enable endpoints.test.ts**
   - [ ] Remove describe.skip at line 21
   - [ ] Create mockEndpoints array (20+ variants)
   - [ ] Set up response snapshots
   - [ ] Target: 15+ tests by T+70

### For GPU Shaders (Gap 5.7) - CRITICAL PATH

1. **Start Phase 1 Implementation**
   - [ ] Create useGPUCompute.ts hook by T+65
   - [ ] Create force-directed.wgsl shader by T+70
   - [ ] Device detection by T+72

2. **Monitor Progress**
   - [ ] Check compilation every 5 min

## RISK ASSESSMENT

### 🟢 LOW RISK
- Wave 1 complete and stable
- Wave 2 Phase 1 fully delivered
- MSW setup now working

### 🟡 MEDIUM RISK
- Wave 2 Phase 2 needs API endpoint tuning (502 responses)
- Gap 5.7 critical path not yet started
- Timeline slip ~10 min from original T+90 estimate

### 🔴 HIGH RISK
- Gap 5.7 GPU shaders (40 min longest task)
- Any delay in Phase 1 (WebGPU setup) compounds
- Performance validation at end (10k nodes <100ms verification)

**Mitigation:**
- Start Gap 5.7 ASAP at T+55-60
- Parallel WebGPU + WebGL development if behind
- Performance testing in parallel with implementation
