# Phase 5: Checkpoint 1 Status Report
**Time:** 2026-02-06 02:27 UTC
**Elapsed:** ~12 minutes (T+12, expect Checkpoint 1 at T+15)
**Mode:** Monitoring & Coordination

---

## EXECUTION SUMMARY

### Wave 1: COMPLETE ✅
- **Status:** Delivered
- **Commit:** 222c51db2 (WebGL visual regression + OAuth events)
- **Tests:** 18 passing (17 visual + 1 publisher)
- **Duration:** ~15 minutes (as planned)

### Wave 2: IN PROGRESS 🟡 (Phase 1 - ETA Checkpoint 1: T+15 min)
**All 3 agents executing in parallel**

| Gap | Agent | Task | Phase 1 Status | Expected Ready |
|-----|-------|------|---|---|
| **5.3** | integration-tests-architect | #6 | Handlers + Data | ~02:30 ✓ |
| **5.4** | general-purpose | #7 | Activities + Workflows | ~02:30 ⏳ |
| **5.5** | general-purpose | #8 | Table Data + Handlers | ~02:30 ✓ |

**Critical Path:** Gap 5.4 - Must complete Phase 1 by T+20 to trigger Wave 3 on schedule

### Wave 3: STANDBY 📋 (Ready for T+20 launch)
- All 3 tasks (#20, #21, #22) prepared with full briefs
- Trigger: Gap 5.4 Phase 1 completion + Pass/Fail signal

---

## KEY METRICS

### Timeline Status (T+12 / T+60 target)
- ✅ Wave 1: 15 min (delivered on schedule)
- 🟡 Wave 2 Phase 1: 12 min elapsed / 15 min target (ON TRACK)
- ⏳ Gap 5.4 Critical Path: Monitor closely for T+20 target

### Test Coverage Projection
- Wave 1: 18 tests ✅ delivered
- Wave 2: 15 tests (8+1+6) executing Phase 1
- Wave 3: 30+ tests ready to deploy (when triggered)
- **Target Total:** 63+ tests

### Resource Allocation
- **Agents:** 6 total (Wave 1: 1 ✅, Wave 2: 3 🟡, Wave 3: 3 📋)
- **Parallel Streams:** 3 active (Wave 2), 1 monitoring (team lead)
- **Support Docs:** 70+ created, comprehensive guidance ready

## CHECKPOINT 1 VALIDATION CHECKLIST (T+15)

### Awaiting Reports From (Expected ~T+15)
- [ ] Gap 5.3: handlers.ts + data.ts complete → Phase 2 ready
- [ ] Gap 5.4: activities.go + workflows.go complete → Phase 2 ready (CRITICAL)
- [ ] Gap 5.5: tableTestItems + API handlers complete → Phase 2 ready

### Validation Tasks (When Reports Arrive)
- [ ] Compilation check: `bun build frontend`, `go build ./backend`
- [ ] TypeScript check: 0 errors required
- [ ] Code review: Verify against code sketches in PHASE_5_3_5_5_IMPLEMENTATION_PLAN.md
- [ ] Approve Phase 2 progression: "✅ Checkpoint 1 ACKNOWLEDGED - All agents proceed to Phase 2"

### If Any Gap Missing at T+15
**Action Protocol:**
1. Send targeted message to agent requesting status update
2. Check if blocker escalation needed
3. Reference support docs: PHASE_5_3_5_5_IMPLEMENTATION_PLAN.md (code sketches lines 423-621)
4. Adjust timeline if critical path affected

---

## CRITICAL PATH MONITORING

**Gap 5.4 (Temporal Snapshots)** is the critical path:
- **Phase 1 Target:** T+15 (activities.go + workflows.go)
- **Phase 2 Target:** T+30 (test setup + service wiring)
- **Phase 3 Target:** T+45 (test re-enabled)
- **Phase 4 Target:** T+60 (1 test passing)
- **Wave 3 Trigger Gate:** Gap 5.4 Phase 1 completion signal

**If Gap 5.4 is delayed:**
- Each 5-min delay pushes Wave 3 start back 5 min
- But parallel execution of Wave 2 Phases 2-4 + Wave 3 Phases 1-3 still saves time overall
- Maximum acceptable delay: +10 min (would push Phase 5 end to T+75 instead of T+65)

## COORDINATION ACTIONS (Team Lead)

### Now (T+12)
- [ ] Monitor for incoming reports (check TaskList, watch for messages)
- [ ] Have validation scripts ready
- [ ] Prepare Wave 3 deployment brief

### At T+15 (Checkpoint 1)
- [ ] Receive 3 reports (Gap 5.3, 5.4, 5.5)
- [ ] Validate Phase 1 deliverables
- [ ] Acknowledge each agent + direct to Phase 2
- [ ] Update master status document

### At T+20 (Gap 5.4 Phase 1 Complete)
- [ ] TRIGGER Wave 3 immediately
- [ ] Send Wave 3 deployment package to api-performance-implementer
- [ ] Launch Tasks #20, #21, #22

### At T+30 (Checkpoint 2)
- [ ] Verify Wave 2 Phase 2 complete (cleanup, test setup)
- [ ] Monitor Wave 3 Phase 1 progress
- [ ] Approve Phase 3 progression
