- [ ] Gap 5.7: WebGPU hook started, WGSL shader path verified
- [ ] Gap 5.8: EdgeSpatialIndex class started
- [ ] All: No compilation errors reported

**Git verification:**
```bash
# Check for new/modified files
git status --short

# Expected patterns:
# M frontend/apps/web/src/__tests__/mocks/handlers.ts (Gap 5.3)

# A backend/internal/temporal/activities.go (Gap 5.4)
# A backend/internal/temporal/workflows.go (Gap 5.4)
# M frontend/apps/web/e2e/fixtures/testData.ts (Gap 5.5)
# And so on...
```

## CRITICAL PATH MONITORING

### Gap 5.4 (Temporal) - Wave 2 Critical Path
- **Started:** T+0
- **Phase 1 Expected:** Complete T+15 (awaiting report now)
- **Phase 2 Expected:** T+15-30 (service integration)
- **Phase 3 Expected:** T+30-45 (test setup)
- **Phase 4 Expected:** T+45-50 (validation)
- **Completion Target:** T+50 (longest Wave 2 task)

### Gap 5.7 (GPU Shaders) - Wave 3 Critical Path
- **Started:** T+15 (just deployed)
- **Phase 1 Expected:** Complete T+27 (WebGPU setup)
- **Phase 2 Expected:** T+27-39 (WebGL fallback)
- **Phase 3 Expected:** T+39-49 (performance benchmarking)
- **Phase 4 Expected:** T+49-55 (integration + validation)
- **Completion Target:** T+55 (longest Wave 3 task)

**Note:** Despite Phase 1 starting at T+15, Gap 5.7 completes at T+55 (not T+27+40). Offset launch + parallel execution = critical path benefit.

## BLOCKER WATCH

**If any agent reports blocker at Checkpoint 1:**

1. **Undefined method/type error:**
   - Reference: Code sketches in WAVE_3_EXECUTION_PLAN.md or PHASE_5_3_5_5_IMPLEMENTATION_PLAN.md
   - Action: Provide code pattern directly

2. **Missing file/import:**
   - Reference: Task description + implementation plan
   - Action: Confirm file path or add import

3. **Cannot resolve:**
   - Reference: PHASE_5_BLOCKER_RESOLUTION_REPORT.md (example resolution)
   - Action: Escalate with error message + attempted fixes

---

## NEXT SYNC POINTS

- Wave 3: Tests passing + GPU speedup verification in progress

### Wave 4 Trigger (T+60)
**When all phases complete:**
- Launch Wave 4 validation sequence
- 5x flake-free verification
- Coverage ≥85% confirmation
- Performance targets validation
