### Gap 5.7: GPU Compute Shaders (Task #21) ⚠️ CRITICAL PATH
**Owner:** api-performance-implementer
**Target:** 50-100x speedup, 10k+ nodes <100ms, WebGPU + WebGL fallback

**Expected Phase Progress (T+40):**
- 🟡 Phase 1 (12 min): WebGPU setup → LIKELY STARTING
- ⏳ Phase 2 (12 min): WebGL fallback → QUEUED
- ⏳ Phase 3 (10 min): Performance testing → QUEUED
- ⏳ Phase 4 (6 min): Integration → QUEUED

**Critical Implementation Points:**
1. **WebGPU Setup (Phase 1, 12 min):**
   - Create `frontend/apps/web/src/hooks/useGPUCompute.ts`
   - Create `frontend/apps/web/src/shaders/force-directed.wgsl` (compute shader)
   - Implement Fruchterman-Reingold force calculation
   - Device detection + fallback logic

2. **WebGL Fallback (Phase 2, 12 min):**
   - Create `frontend/apps/web/src/shaders/force-directed.glsl`
   - Texture ping-pong GPGPU pattern
   - Format conversion (positions as texture data)

3. **Performance Validation (Phase 3, 10 min):**
   - 10k node benchmark: target <100ms
   - Memory usage: <1GB
   - Cross-browser testing

4. **Integration (Phase 4, 6 min):**
   - Wire into `SigmaGraphView.tsx`
   - Performance visualization (FPS, compute time)
   - Benchmark test suite

**Reference:** `/docs/reports/PHASE_5_GAPS_5_6_5_7_5_8_IMPLEMENTATION_PLAN.md` (sections 2, code sketches lines 487-575)

**Timeline Risk:** This is the longest task (40 min). Expected completion: T+80

**Next Milestone:** WebGPU hook + shader by T+55

---

### Gap 5.8: Spatial Indexing (Task #22)
**Owner:** api-performance-implementer
**Target:** 98% culling accuracy, <5% memory, <50ms for 5k edges

**Expected Phase Progress (T+40):**
- 🟡 Phase 1 (8 min): Spatial index structure → QUEUED (after Gap 5.6 Phase 1)
- ⏳ Phase 2 (8 min): Visibility computation → QUEUED
- ⏳ Phase 3 (10 min): Performance optimization → QUEUED
- ⏳ Phase 4 (6 min): Integration → QUEUED

**Files to Create:**
- `frontend/apps/web/src/lib/graph/spatial-index.ts` (EdgeSpatialIndex class)
- `frontend/apps/web/src/lib/graph/viewport-culling.ts` (visibility utilities)
- Tests: `spatial-index.test.ts`, `SigmaGraphView.spatial-index.test.tsx`

**Next Milestone:** Spatial index structure by T+60

## WAVE 1 VERIFICATION STATUS ✅

### Gap 5.1: WebGL Visual Regression
- ✅ 4 unit tests un-skipped (SigmaGraphView tests)
- ✅ 13+ Playwright visual regression tests created
- ✅ Visual snapshots with 2% tolerance
- ✅ Committed in 222c51db2

### Gap 5.2: OAuth Event Publisher
- ✅ event_publisher.go created (249 lines)
- ✅ event_publisher_test.go >80% coverage
- ✅ 8+ event types + masking verified
- ✅ NATS JetStream integration complete
- ✅ Blocker resolved (method signatures aligned)
- ✅ Committed in 222c51db2

**Test Results:** 15+ tests passing (no failures)

---

## CRITICAL PATH ANALYSIS

### Dependency Chain
1. **Wave 2 Phase 1 → Wave 2 Phase 2** (T+20 → T+30): MSW handlers must be in place before CRUD re-enable
2. **Gap 5.3 Phase 2 done → Gap 5.4 can proceed independently** (async, no dependency)
3. **Gap 5.6 Phase 1 → Wave 3 Phase 2** (T+50 → T+60): API fixtures unblock other gaps
4. **Gap 5.7 Phase 1 → Gap 5.8 Phase 1** (T+55 → T+60): GPU task starts before spatial (sequential)

### Critical Path Item: Gap 5.7 GPU Shaders
- **Longest task:** 40 minutes (12+12+10+6)
- **Dependency:** None (starts immediately at T+40)
- **Completion ETA:** T+80
- **Timeline Risk:** HIGH - any delays compound to final completion
- **Mitigation:** Parallel WebGPU + WebGL shader development recommended

- [ ] Confirm compilation status (no build errors)
- [ ] Check for milestone completions

### Every 15 minutes (scheduled):
- [ ] Validate against checkpoint success criteria above
- [ ] Assess timeline impact of any delays
- [ ] Prepare next checkpoint reporting

### If Blocker Detected:
1. Identify blocker type (architecture / code snippet / test setup / dependency)
2. Reference `/docs/reports/PHASE_5_BLOCKER_RESOLUTION_REPORT.md` for resolution pattern
3. Escalate to appropriate agent with full context
4. Track blocker impact on timeline
