# Phase 5: Final Coordination Brief

**Status:** 🟢 ALL SYSTEMS EXECUTING
**Time:** 2026-02-06 02:30+ UTC
**Execution Mode:** Full 6-gap parallel (Wave 1-3 active)

---

## HEADLINE STATUS

✅ **Wave 1:** COMPLETE (18 tests verified)
🟡 **Wave 2:** LIVE Phase 1 (3 agents executing in parallel)
🟡 **Wave 3:** ACTIVE & PARALLEL (ready for T+20 dispatch)

**Total:** 6 gaps executing, 66+ tests target, 90-120 min wall-clock

---

## EXECUTION SNAPSHOT

### Wave 2: PHASE 1 NOW LIVE (T+0 to T+15)
- **Gap 5.3:** MSW handlers + test data (integration-tests-architect, Task #6)
- **Gap 5.4:** activities.go + workflows.go (general-purpose, Task #7) ⚠️ CRITICAL PATH
- **Gap 5.5:** tableTestItems + API handlers (general-purpose, Task #8)

**Checkpoint 1 ETA:** ~T+15 min (handlers, activities, data ready)
**Success Criteria:** All 3 agents report Phase 1 complete with deliverables

### Wave 3: STANDBY FOR T+20 DISPATCH
- **Gap 5.6:** API endpoints (Task #20, 30 min)
- **Gap 5.7:** GPU shaders (Task #21, 40 min) ⭐ CRITICAL
- **Gap 5.8:** Spatial indexing (Task #22, 20 min)

**Trigger:** Gap 5.4 test completion (~T+20)
**Action:** Immediately dispatch upon signal

---

## CRITICAL PATH: Gap 5.4 → Gap 5.7

```
Gap 5.4 Timeline (Temporal Snapshots):
├─ T+0-15: Phase 1 (activities.go + workflows.go) 🟢 LIVE
├─ T+15: Checkpoint 1 report due ⏳ IMMINENT
├─ T+15-20: Phase 1 completion + test execution
├─ T+20: Test complete → Wave 3 GPU trigger 🚀
└─ Unblocks: Gap 5.7 (GPU shaders, 40 min)
```

**Risk:** <20 min buffer if slips
**Mitigation:** Code templates + architecture pre-provided
**Status:** ON TRACK

---

## TEAM ASSIGNMENTS

### Wave 2 Leads
- **integration-tests-architect:** Gap 5.3 (8 tests)
- **general-purpose (×2):** Gaps 5.4 (1 test) + 5.5 (6 tests)

### Wave 3 Leads

## IMMEDIATE ACTIONS

**Now (T+0 to T+15):**
1. ✅ Monitor TaskList for progress updates
2. ✅ Await Checkpoint 1 reports (~02:30 UTC)
3. ✅ Prepare acknowledgment messages
4. ✅ Have Wave 3 dispatch brief ready

**At Checkpoint 1 (~02:30):**
1. Receive 3 Phase 1 complete messages
2. **CRITICAL:** Verify Gap 5.4 "on schedule"
3. Acknowledge all agents
4. Direct to Phase 2
5. **Dispatch Wave 3 immediately** (if Gap 5.4 ready)

**At T+20 (~02:35):**
1. Gap 5.4 test completion signal expected
2. Wave 3 GPU agents should be executing
3. Confirm all 3 Wave 3 tasks active

**Continuous (All Checkpoints):**
1. Acknowledge reports
2. Verify deliverables
3. Monitor critical path (Gap 5.4 → 5.7)
4. Direct next phases
5. Escalate blockers

---

## BLOCKERS & ESCALATION

**If Any Agent Blocked:**
1. Read blocker message
2. Check architecture docs (relevant sections)
3. Provide specific guidance or code reference
4. If still stuck: offer additional support or escalate

**If Gap 5.4 Delayed:**
- At T+18: "Gap 5.4, what's your status?"
- If <5 min delay: continue monitoring
- If ~10 min delay: adjust Wave 3 start time
- If >15 min delay: investigate + provide support

**If Tests Failing:**
- Check test expectations in implementation plan
- Check code sketches for reference
- Provide debug steps or guidance
- Escalate if beyond support
