# Phase 5: Team Lead Handoff & Monitoring Protocol

**Status:** 🟢 ALL EXECUTING - TEAM LEAD ACTIVE
**Current Time Estimate:** T+30-45 min into 90-min execution
**Team Lead:** claude-haiku (main context)
**Coordinator:** Integration-Tests-Implementer (async)

---

## EXECUTING AGENTS STATUS

### Wave 2 (Frontend Integration) - Tasks #6, #7, #8
**Status:** 🟡 IN PROGRESS (concurrent)
**Expected Progress:** Phase 1-2 done → Phase 3 in progress

| Task | Gap | Agent Type | Scope | ETA | Critical |
|------|-----|-----------|-------|-----|----------|
| #6 | 5.3 | integration-tests-architect | MSW handlers + async helpers (8 tests) | T+40 | No |
| #7 | 5.4 | general-purpose | Temporal activities + workflows (1 test) | T+50 | **YES** ← Longest Wave 2 task |
| #8 | 5.5 | general-purpose | A11y tests + WCAG (6 tests) | T+35 | No |

**Wave 2 Dependencies:** None (parallel at gap level, sequential within each gap)

### Wave 3 (Performance) - Tasks #20, #21, #22
**Status:** 🟡 IN PROGRESS (concurrent)
**Expected Progress:** Phase 1-2 done → Phase 3 in progress

| Task | Gap | Agent Type | Scope | ETA | Critical |
|------|-----|-----------|-------|-----|----------|
| #20 | 5.6 | integration-tests-implementer | API contract validation (15+ tests) | T+40 | No |
| #21 | 5.7 | integration-tests-implementer | GPU compute shaders + WebGL fallback (10+ tests) | T+40 | **YES** ← Longest Wave 3 task (CRITICAL PATH) |
| #22 | 5.8 | integration-tests-implementer | Spatial indexing + viewport culling (8+ tests) | T+32 | No |

**Wave 3 Dependencies:** None (parallel at gap level, sequential within each gap)

**Critical Path Warning:**
- Gap 5.7 is longest task: 40 min (WebGPU setup + WebGL fallback + benchmarking)
- Even though Wave 2 is T+50, Wave 3 critical path is T+40
- Overall Phase 5 critical path: max(T+50, T+40) = **T+50 min** (Gap 5.4 Temporal longer than GPU!)

## TEAM LEAD RESPONSIBILITIES

### Primary: Monitor Checkpoints
Execute synchronous checkpoint monitoring at:
- **T+15:** Check TaskList for phase reports (Gap discovery + file changes)
- **T+30:** Check TaskList for phase reports (Code creation halfway)
- **T+45:** Check TaskList for phase reports (Tests being written)
- **T+60:** Prepare Wave 4 validation trigger

### Secondary: Catch Blockers
Watch for messages from agents on:
- Undefined methods / compilation errors
- Missing dependencies
- API contract mismatches
- Unexpected test failures

**If Blocker Reported:**
1. Read message immediately
2. Check: `/docs/reports/PHASE_5_BLOCKER_RESOLUTION_REPORT.md`
3. Check: Master plan code sketches (lines 423-651 per gap)
4. **Provide direct answer from plans or escalate with full context**

### Tertiary: Coordinate Wave 4
When all Wave 2 + Wave 3 tasks report completion:
1. Verify 80+ tests passing (TaskList shows all in_progress → ?)
2. Trigger Wave 4 validation sequence
3. Oversee 5x flake verification
4. Confirm coverage ≥85%
5. Approve final 5 commits
6. Validate Phase 5 completion report

**What to check:**
- [ ] Task #6: 8/8 tests passing or reported
- [ ] Task #7: 1/1 test passing or reported

**What to expect:**
- Phase 4 complete (all tests passing)
- 80+ tests total passing
- Coverage ≥85% confirmed
- Performance targets met

**Action:**
- If all passing: "Triggering Wave 4 validation - 5x flake verification → coverage → performance → commits → report"
- If failures: Work with agents to resolve before Wave 4

## BLOCKER ESCALATION MATRIX

| Blocker Type | Resolution | Who | Timeout |
|--------------|-----------|-----|---------|
| **Undefined method** | Check code sketches (line N), add method or fix signature | Team Lead | 5 min |
| **Missing file** | Check master plan, create file with scaffolding | Team Lead | 3 min |
| **Test fails** | Debug assertion, check mock data, fix code | Team Lead + Agent | 10 min |
| **Compilation error** | Fix imports, check types, resolve conflicts | Team Lead + Agent | 5 min |
| **API mismatch** | Verify contract, check mock responses, update snapshots | Team Lead + Agent | 8 min |
| **Cannot resolve** | Escalate to main context with full error + attempted fixes | Team Lead | N/A |

## PARALLEL EXECUTION BENEFITS

**Parallelization Achieved:**
- Wave 2 (3 gaps) executing concurrently: max(40, 50, 35) = 50 min vs 125 min sequential
- Wave 3 (3 gaps) executing concurrently: max(40, 40, 32) = 40 min vs 112 min sequential
- Waves 2+3 executing in parallel: 50 min vs 237 min sequential
- Overall: **~90 min vs 300+ min sequential = 70% time savings**

**Critical Path:**
- Gap 5.4 (Temporal workflows) = 50 min ← LONGEST in Wave 2
- Gap 5.7 (GPU shaders) = 40 min (Wave 3, masked by Wave 2)
- **Overall critical path = 50 min (Gap 5.4) + Wave 4 (~30 min) = ~80 min total**

---

## EXPECTED FINAL DELIVERY
