# Phase 5: Checkpoint 1 - Corrected Execution State

**Time:** T+15 minutes
**Status:** 🟢 WAVE 1 DELIVERED, CHECKPOINT 1 VALIDATION UNDERWAY
**Coordinator:** claude-haiku

## EXECUTION STATE CORRECTION

### What Changed
Previous documentation had Wave 1 estimated to complete at T+30. **Actual result:** Wave 1 completed at **T+15** - 15 minutes ahead of schedule.

This is excellent for timeline and enables better Wave 2-3 parallelization.

## COORDINATOR STATUS & ACTIONS

### Current Role
**Coordinator:** claude-haiku (team-lead)

### Actions Completed (T+0 to T+15)
✅ Created execution plans (500+ line docs with code sketches)
✅ Spawned Wave 1 team (visual-regression-implementer)
✅ Spawned Wave 2 teams (integration-tests-architect, general-purpose)
✅ Prepared Wave 3 (api-performance-implementer staged)
✅ Wave 1 delivered early (commit 222c51db2)

### Current Actions (T+15 - NOW)
✅ Created Checkpoint 1 Validation Protocol
✅ Monitoring for Wave 2 Phase 1 reports (expected within 5-10 min)
✅ Acknowledged Wave 3 team (ready for T+50 trigger)
✅ Prepared Phase 2 briefing templates
✅ Standing by for compilation validation

### Next Actions (T+15-25)

2. Validate compilation (bun, go, python)
3. Check for blockers (escalate if needed)
4. Send Phase 2 briefings to Wave 2 agents
5. Begin Wave 2 Phase 2 monitoring

### Awaiting (Next 5-10 min)

## CHECKPOINT 1 SUCCESS CRITERIA

**For Validation (by T+25):**
- [ ] Gap 5.3: MSW handlers + test data (files confirmed)
- [ ] Gap 5.4: activities.go + workflows skeleton (files confirmed)
- [ ] Gap 5.5: tableTestItems + items handler (files confirmed)
- [ ] Compilation: bun build, go build, python import all pass
- [ ] Blockers: 0 unresolved (or provided solutions)
- [ ] Status: All 3 agents ready for Phase 2

**Success Indicator:** All 6 criteria met = ✅ CHECKPOINT 1 SUCCESS

---

## CRITICAL PATH MONITORING

**Critical Task:** Gap 5.7 (GPU Compute Shaders)

**Why Critical:**
- Longest task: 40 minutes total
- Starts at T+50 (when Wave 3 launches)
- Expected completion: T+90 (determines overall Phase 5 finish)
- Any delay compounds to final completion

**Monitoring Checkpoints:**
1. **T+50:** Task #21 launched, Phase 1 starts
2. **T+55:** Phase 1 >50% (hook skeleton, shader started)
3. **T+65:** Phase 1 complete, Phase 2 starting (WebGL fallback)
4. **T+75:** Phase 2-3 active (performance testing)
5. **T+90:** All phases complete (50-100x speedup verified)

**Risk Mitigation:**
- If behind by >5 min at any checkpoint: Escalate immediately
- Provide direct code solutions from implementation-plan.md
- Consider parallel WebGPU + WebGL development
