## CRITICAL PATH ANALYSIS

**Gap 5.7 (GPU Compute Shaders) = Longest Task = Determines Phase 5 Completion**

```
Timeline impact:
- Wave 1 complete: T+40
- Wave 2 complete: T+70 (Gaps 5.3-5.5 all done with Phase 3)
- Wave 3 parallel execution:
  * Gap 5.6 (30 min): T+60→T+90
  * Gap 5.8 (30 min): T+60→T+90
  * Gap 5.7 (40 min): T+60→T+100 ← LONGEST
- Phase 5 completion: T+100 (wait for longest task)
```

**Each 5-minute delay in Gap 5.7 = 5-minute delay in Phase 5 completion**

**Escalation thresholds:**
- T+72: If Phase 1 (WebGPU) <50% complete → escalate
- T+80: If Phase 2 (WebGL) not started → escalate
- T+90: If Phase 3-4 not started → escalate
