### 🚀 WAVES EXECUTING IN PARALLEL

| Wave | Gaps | Tasks | Status | Progress | Duration | ETA | Critical |
|------|------|-------|--------|----------|----------|-----|----------|
| **1** | 5.1-5.2 | #13-15 | ✅ EXECUTING | Phase 1 active | T+0→T+40 | T+40 | - |
| **2** | 5.3-5.5 | #6, #7, #8 | ✅ EXECUTING | Phase 1 active | T+0→T+60 | T+60 | ⭐ Gap 5.4: 50 min |
| **3** | 5.6-5.8 | #20, #21, #22 | 🟢 LAUNCHING | Phase 1 start | T+15→T+55 | T+55 | ⭐ Gap 5.7: 40 min |
| **4** | Validation | - | ⏳ STAGED | Ready | T+60→T+90 | T+90 | - |

### 📊 CRITICAL PATH ANALYSIS

**Overall Phase 5 Critical Path:**
- Wave 1: T+40 (independent)
- Wave 2: T+60 (3 gaps × ~20 min avg)
- Wave 3: T+55 (launched at T+15, completes before Wave 2)
- Wave 4: T+30 (validation only)
- **Total: T+60 min** (Wave 2 Phase 4 is final blocker)

**Individual Task Critical Paths:**
1. Gap 5.4 (Temporal workflows): 50 min → T+50
2. Gap 5.7 (GPU shaders): 40 min → T+55 (but launches T+15, completes T+55)
3. Wave 2 Phase 4: 15 min → T+60 (final validation)

### 📋 CHECKPOINT SCHEDULE

| **T+30** | Checkpoint 2 | Wave 2 Phase 2 + Wave 3 Phase 1 | Acknowledge → Phase 3 |
| **T+45** | Checkpoint 3 | Wave 2 Phase 3 + Gap 5.6 done | Monitor critical path |
| **T+55** | GPU Verification | Gap 5.7 speedup confirmed | Prepare Wave 4 trigger |
| **T+60** | Checkpoint 4 | Wave 2 Phase 4 (15/15) + Wave 4 trigger | Launch validation |
| **T+90** | Phase 5 Complete | All tests passing + Wave 4 done | 80+ tests, Q=97-98 |

## MONITORING & COORDINATION

### Live Monitoring Points
✅ **TaskList:** Checking for task metadata updates every 10-15 min
✅ **Messages:** Watching for checkpoint reports and blocker escalations
✅ **Git:** Verifying new/modified files as phases complete
✅ **Compilation:** Checking for build errors at phase transitions
✅ **Critical Path:** Monitoring Gap 5.4 (Wave 2) and Gap 5.7 (Wave 3)

### Checkpoint Acknowledgment Protocol
**When reports received, send:**
```
✅ Checkpoint N ACKNOWLEDGED

Phase N Complete:
- [Gap/Task]: [scope] ✅
- [Gap/Task]: [scope] ✅
- [Gap/Task]: [scope] ✅

Proceed to Phase N+1 (expected completion T+XY)
```

### Blocker Escalation Protocol
**If agent reports issue:**
1. Check PHASE_5_BLOCKER_RESOLUTION_REPORT.md (example: event publisher method mismatch)
2. Reference code sketches from execution plans (lines 423-651 or WAVE_3_EXECUTION_PLAN.md)
3. Provide direct answer OR escalate with full context (error + attempted fixes)

## TIMELINE CONFIDENCE

**High Confidence:**
- ✅ Wave 1 delivery (T+40) - Visual regression + OAuth completed in previous session
- ✅ Wave 3 launch (T+15) - All tasks authorized, code sketches ready
- ✅ Checkpoint protocol (every 15 min) - Clear reporting format established
- ✅ Blocker resolution (code sketches ready) - References prepared

**Medium Confidence:**
- ⚠ Wave 2 Phase 4 (T+60) - Depends on smooth Phase 1-3 progression
- ⚠ Gap 5.7 GPU speedup (T+55) - GPU implementation is complex, WebGL fallback tested

**Risks & Mitigations:**
1. **Risk:** Gap 5.4 (Temporal) takes longer than 50 min
   - **Mitigation:** Monitoring closely at T+30, T+45 checkpoints
2. **Risk:** Gap 5.7 GPU shader compilation fails
   - **Mitigation:** WebGL fallback available, test patterns provided in code sketches
3. **Risk:** Tests have environmental dependencies
   - **Mitigation:** MSW handlers + fixtures provided in WAVE_3_EXECUTION_PLAN.md
