## T+4h CHECKPOINT (IMMINENT)

**Expected:** Change detection (line 621) complete
**Components to Report:**
- ✅ Change detection logic implemented
- ✅ 15+ unit tests passing
- ✅ Git commit created
- ✅ No blockers identified
- ✅ Parallel work progress

**Who to Hear From:**
1. **Sync Engine Implementer** - Change detection status
2. **Handler Registrar (go-build-fixer)** - Handler registration progress + build status
3. **Auth System Implementer** - OAuth handler status
4. **API Type Safety Specialist** - OpenAPI spec progress
5. **Others** - Checkpoint progress updates

**Coordinator Actions at T+4h:**
- ✅ Receive all agent checkpoint reports
- ✅ Verify no blockers
- ✅ Confirm T+4h→T+8h transition approval
- ✅ Update this dashboard
- ✅ Identify any escalations needed

---

## SUCCESS CRITERIA

### Phase 3 Complete (T+24h)
- ✅ Auth system end-to-end functional
- ✅ 40+ handlers registered and tested
- ✅ OpenAPI spec 100% complete
- ✅ Sync engine all 4 TODOs implemented
- ✅ 35+ production tests passing
- ✅ Zero new compilation errors

### Per-Checkpoint Success
- **T+4h:** Change detection complete, no build regressions, parallel work on track
- **T+8h:** Pull logic complete, change detection tested, no integration issues
- **T+12h:** Apply changes complete, 3-way merge logic verified, no edge case failures
- **T+16h:** Conflict handling complete, .conflict file creation working
- **T+24h:** All 4 TODOs complete, 35+ tests passing, production ready

---

## BLOCKER ESCALATION PATH

**If any agent reports a blocker:**
1. ✅ Log it here with timestamp
2. ✅ Provide immediate support/workaround
3. ✅ If unresolvable: Escalate to team-lead
4. ✅ Update timeline impact

**Common Blockers & Mitigations:**
- **Compilation error:** Code Reviewer/QA provides fix patterns
- **Missing dependency:** Blocker Resolution Agent resolves
- **Design issue:** Team lead + agent brainstorm solution
- **Test failure:** Investigate root cause, extend timeline if needed

## REAL-TIME TRACKING

### Current Time: ~02:42 UTC (Session Continuation, T+42 Approx)
### Next Checkpoint: T+4h (~06:42 UTC)
### Time Until Checkpoint: ~2 hours

**Agents Status as of T+42:**

✅ **CONFIRMED ACTIVE (2/9):**
- ✅ go-build-fixer: Handler registrar support EXECUTING (auth integration, 40+ handlers)
- ✅ docs-reorganizer (Auth System Implementer): OAuth implementation EXECUTING (JWT refresh, DB session)

⏳ **STATUS PENDING (7/9) - URGENT COLLECTION IN PROGRESS:**
