## IMMEDIATE ACTIONS (T+0 NOW)

### 1. WAVE 1 ASSIGNMENT (RIGHT NOW)
**Action:** Team lead assigns visual-regression-implementer to tasks #13-17

**Tasks Ready:**
- [ ] Task #13: Un-skip 4 WebGL unit tests (10 min)
- [ ] Task #14: Create 13+ Playwright visual specs (20 min)
- [ ] Task #15: OAuth event publisher (25 min)
- [ ] Task #16: NATS JetStream Consumer (optional)
- [ ] Task #17: Wire OAuth to Event Publisher (optional)

**Expected Output by T+40:**
- 4 WebGL unit tests passing
- 13+ Playwright visual regression tests
- 1 OAuth event publisher test
- **Total: 17+ tests**

**Parallel with Wave 2:** No dependency conflict - execute simultaneously

### 2. WAVE 2 CHECKPOINT 1 (T+15)
**Action:** Monitor for Phase 1 completion reports

From:
- Gap 5.3 (integration-tests-architect): MSW handlers + data
- Gap 5.4 (general-purpose): activities.go + workflows.go
- Gap 5.5 (general-purpose): tableTestItems + API handlers

**Validation:** Compilation clean, no blockers, ready for Phase 2

### 3. WAVE 3 TRIGGER GATE (T+20)
**Condition:** Gap 5.4 test passes (temporal snapshot executes)

**Action When Triggered:**
- Signal: "Wave 3 unblocked - Deploy tasks #20, #21, #22 NOW"
- Launch: api-performance-implementer with all 3 tasks in parallel
- Timeline: T+20 to T+80-90 (60 min execution)

---

## CRITICAL PATH MONITORING

### Wave 1 (T+0-40)
- No critical dependencies
- Independent from Wave 2-3
- Target: 17+ tests by T+40
- Risk: LOW (no cross-dependencies)

### Wave 2 (T+0-60)
- Phase 1 → Phase 2 dependency (handlers before CRUD tests)
- Checkpoint gates at T+15, T+30, T+45
- Target: 15 tests by T+60
- Risk: MEDIUM (phase-to-phase dependencies)

### Wave 3 (T+20-90) ⭐ CRITICAL PATH
- Trigger gate: Gap 5.4 test completion (~T+20)
- Longest task: Gap 5.7 (GPU shaders) = 40 min
- Phase 1-4 parallel execution (all 3 gaps simultaneously)
- Target: 30+ tests by T+90
- Risk: HIGH on Gap 5.7 (longest task determines completion)

**Monitoring Gap 5.7:**
- T+25: Phase 1 >25% (WebGPU setup starting)
- T+35: Phase 1 >75% (hook skeleton, shader created)
- T+45: Phase 1 complete (no TS errors)
- T+55: Phase 2 active (WebGL fallback)
- T+70: Phase 3-4 active (performance validation)
- T+90: Complete (50-100x speedup verified)
