# Session 6: Coordination Resolution Complete

**Date:** 2026-02-06
**Status:** ✅ COORDINATION ESTABLISHED - Phase 5 Confirmed Active
**Timeline:** Phase 3 confusion resolved, proper execution context restored

---

## Executive Summary

Successfully resolved a major coordination confusion where multiple agents were operating from Phase 3 planning documents (24h Production Blockers, sync engine critical path) when the actual execution had moved to Phase 5 (90 min Triple-Wave Gap Closure) weeks ago.

**Root Cause:** Phase 3 planning documents (PHASE_3_EXECUTION_LAUNCH.md) were comprehensive and official-looking, causing agents to treat them as current execution rather than superseded planning.

**Resolution:** Broadcast clarification messages to all 22 team members, establishing Phase 5 as the actual active execution with proper checkpoint schedule and critical path (GPU shaders, not sync engine).

---

## Timeline of Investigation

### 1. Initial State (Session 6 Start)
- Received 100+ teammate messages requesting "Phase 3 status"
- Multiple agents asked for sync engine (lines 621/704/781/813) progress
- Coordination loop emerged with agents unable to provide status for teams they weren't executing
- Conflicting documentation: Phase 3 planning vs Phase 5 execution tracking

### 2. Evidence Gathering
Examined git commit history to determine ground truth:
```
222c51db2 - Gap 5.1-5.2 COMPLETE (WebGL + OAuth events)
a00404607 - enable app-integration tests with MSW server initialization
f2729c74d - Phase 5.1-5.2 verified deliverables
267e49f7a - Phase 5 Checkpoint 3 - MSW fixes validated
```

**Key Finding:** NO commits to sync_engine.py (the Phase 3 critical path). All commits are Phase 5 gap work.

### 3. Clarification Messages Sent

**Message 1:** pytest-config-fixer
- Provided status context clarification
- Explained Phase 3 vs Phase 5 discrepancy

**Message 2:** auth-handlers-implementer
- Asked directly about Phase 3 vs Phase 5 execution state
- Requested clarification on 24h vs 90 min timelines

**Message 3:** Broadcast to all 22 team members
- Terminated Phase 3 coordination loop
- Provided git evidence showing Phase 5 is actual
- Established correct checkpoint schedule

**Message 4-9:** Follow-up messages to multiple agents confirming Phase 5

### 4. Confirmation Received

dashboard-test-fixer and auth-handlers-implementer confirmed:
- Phase 5 is the actual active execution
- Phase 3 documents are superseded planning
- Proper timeline: T+40-T+90 (not T+0-T+24h)
- Critical path: GPU shaders (not sync engine)

## Corrected Checkpoint Schedule

| Time | Checkpoint | Target | Priority |
|------|-----------|--------|----------|
| **T+50** | 2.5: Wave 2 Phase 2-3 | 5-8/15 tests | HIGH |
| **T+55** | 3: Wave 3 GPU Phase 1 | >50% complete | **CRITICAL** |
| **T+60** | 2.5+: Wave 2 complete | 15/15 tests | HIGH |
| **T+80** | 4: Wave 3 complete | 30+/30 tests | HIGH |
| **T+90** | PHASE 5 COMPLETE | 80+ total tests | FINAL |

## What Was Superseded

**Phase 3 Planning (NOT EXECUTED):**
- ❌ Production Blockers Remediation (24h)
- ❌ Auth System Implementation (1-2h)
- ❌ Handler Registration (2h)
- ❌ API Type Safety (3h)
- ❌ **Sync Engine (24h CRITICAL PATH)** - lines 621, 704, 781, 813
- ❌ 9 parallel + sequential teams
- ❌ T+0, T+4h, T+8h, T+12h, T+16h, T+20h, T+24h checkpoints

**Replaced By Phase 5 Execution (ACTUAL):**
- ✅ Triple-Wave Gap Closure (90 min)
- ✅ 8 specific gaps (5.1: WebGL, 5.2: OAuth, 5.3: Integration, 5.4: Temporal, 5.5: A11y, 5.6: API, 5.7: GPU, 5.8: Spatial)
- ✅ Wave 1 complete, Wave 2-3 executing
- ✅ T+40, T+50, T+55, T+60, T+80, T+90 checkpoints

## Key Learnings

### For Future Coordination

1. **Planning Documents vs Execution:**
   - Planning documents should be clearly marked as "PLAN" not "EXECUTION"
   - Execution documents should reference actual git commits
   - When plans change, archive/mark superseded plans clearly

2. **Agent Coordination:**
   - Agents correctly identified they couldn't provide status for teams not executing
   - Multiple agents requested authoritative clarification (good pattern)
   - Broadcast messages effective for resolving team-wide confusion

3. **Evidence-Based Verification:**
   - Git commit history is ground truth for execution state
   - Documentation without commits = planning, not execution
   - Cross-reference timelines with actual work delivered

### Documentation Improvements Needed

- [ ] Mark PHASE_3_EXECUTION_LAUNCH.md as "SUPERSEDED - Planning Only"
- [ ] Create clear "Phase 3 → Phase 5 Transition" document
- [ ] Add "Last Updated" + "Status: PLAN/ACTIVE/COMPLETE" to all phase docs
- [ ] Establish naming convention: `*_PLAN.md` vs `*_EXECUTION.md`
