## Decision Points & Next Actions

### NOW (Before T+15)
- [ ] Monitor Wave 1 Phase 1 progress
- [ ] Review Wave 2 documentation
- [ ] Prepare agent assignments for T+15
- [ ] Identify 3 agents for Tasks #20, #21, #22

### At T+15 (CRITICAL CHECKPOINT)
- [ ] Receive Wave 1 Checkpoint 1 reports (3 agents)
- [ ] Acknowledge all 3 agents
- [ ] **IMMEDIATELY assign Wave 2 agents to Tasks #20, #21, #22**
- [ ] Announce dual-wave coordination protocol

### T+15 to T+60
- [ ] Monitor Wave 1 Checkpoints 2, 3, 4
- [ ] Monitor Wave 2 Checkpoint 1 (starting)
- [ ] Coordinate any issues (unlikely - independent gaps)

### T+60 to T+120
- [ ] Wave 1 complete (all 15/15 tests)
- [ ] Wave 2 continues (Checkpoints 2-4)
- [ ] Prepare final Phase 5 completion report

## Risk Assessment

### Wave 1 Risks (MINIMAL)
- ✅ All code sketches provided
- ✅ Clear dependencies identified
- ✅ Sync points established
- ✅ Agent support available

### Wave 2 Risks (LOW)
- ✅ Independent from Wave 1
- ✅ Full architecture documented
- ✅ Code ready to implement
- ✅ No blocking dependencies

**Overall Risk Level:** LOW (all dependencies resolved, documentation complete)

---

## Contingency Plans

**If Wave 1 agent blocked:**
- Remaining 2 Wave 1 agents continue (no dependency)
- Architect provides real-time support
- Wave 2 launch not affected

**If Wave 2 agent blocked:**
- Remaining 2 Wave 2 agents continue (no dependency)
- Wave 1 already complete, not affected
- Can shift resources as needed

---

## Final Recommendations

1. **Launch Wave 2 at T+15 immediately** (no delay)
2. **Maintain 15-minute checkpoint cadence** for both waves
3. **Assign 3 new agents to Tasks #20, #21, #22** at T+15
4. **Plan for Phase 6 after Wave 2 completes** (T+120)

---

## Summary

**Phase 5 is executing at optimal efficiency with dual-wave parallel execution:**

- ✅ Wave 1 (5.3-5.5): 15 tests, 3 agents, T+0 to T+60
- ✅ Wave 2 (5.6-5.8): 30+ tests, 3 agents, T+15 to T+120
- ✅ Total: 45+ tests, 6 agents, 90-120 min wall-clock
- ✅ Savings: 60-90 minutes vs sequential approach

**Status:** EXECUTING SUCCESSFULLY ✅
