# Phase 5: Checkpoint 2.5 Monitoring (T+45-50)

**Date:** 2026-02-06 T+45-50 minutes
**Coordinator:** claude-haiku (team-lead)
**Status:** 🟢 ACTIVE MONITORING

---

## CHECKPOINT 2.5 ROLE

At T+45-50, the coordinator monitors progress toward T+50 success criteria and **validates that Wave 2 Phase 2 is underway** across all 3 gaps.

### Critical Question
**Are all 3 Wave 2 agents proceeding to Phase 2 (test re-enable & advanced setup)?**

- Gap 5.3 (integration-tests-architect): Tests starting to re-enable → expect 3-4 tests green
- Gap 5.4 (general-purpose): Workflows complete → expect 1 test green or near-passing
- Gap 5.5 (general-purpose): WCAG setup underway → expect 2-3 tests green

---

## REAL-TIME MONITORING CHECKLIST

### Every 5 minutes: Quick Health Check
```
☐ TaskList shows #6, #7, #8 still in_progress
☐ No error messages in agent feed
☐ No git conflicts reported
☐ No TS/Go/Python compilation errors
```

### At T+45 (Now or Soon): Progress Assessment
```
☐ Check Wave 2 agent messages for Phase 2 start reports
☐ Verify Gap 5.7 is in active Phase 1 (WebGPU setup)
☐ Count: How many tests are passing now?
  - Expected: 5-8 tests total across all waves
  - Minimum acceptable: 4+ tests
☐ Assess critical path:
  - Gap 5.7 should be ~50% through Phase 1
  - No "stuck" indicators
```

### At T+50 (Final Validation): Checkpoint Success
```
☐ Gap 5.3: 4-6/8 tests passing
☐ Gap 5.4: 1/1 test passing OR very close
☐ Gap 5.5: 3-6/6 tests passing
☐ Wave 2 subtotal: 8+ tests passing
☐ Gap 5.7: Phase 1 >60% complete (shader compiling/device detected)
☐ No blockers reported
```

## EXPECTED PROGRESS TIMELINE

### T+40 → T+45 (Right Now)
**Wave 2 Gap 5.3 (integration-tests-architect):** Phase 2 Underway
- Task: Re-enable CRUD integration tests
- Status: Handlers created (Phase 1 ✅), now adding test re-enable + async helpers
- Expected by T+50: 4-6 tests passing

**Wave 2 Gap 5.4 (general-purpose):** Phase 1-2 Bridge
- Task: Wire activities + workflows together
- Status: Activities created (Phase 1 ✅), workflows nearly complete
- Expected by T+50: 1/1 test passing or very close

**Wave 2 Gap 5.5 (general-purpose):** Phase 2 In Progress
- Task: Set up WCAG testing infrastructure
- Status: Test data created (Phase 1 ✅), handlers added, now setting up fixtures
- Expected by T+50: 3+ tests passing

**Wave 3 Gap 5.6:** Phase 1 Full Speed
- Task: Create mock endpoints + handlers
- Status: Just launched (T+40), Phase 1 active
- Expected by T+50: 80%+ complete (handlers ready to test)

**Wave 3 Gap 5.7 (CRITICAL PATH):** Phase 1 Active
- Task: WebGPU hook + shader setup
- Status: Should be creating useGPUCompute.ts + force-directed.wgsl
- Expected by T+50: Shader compiling or near compile (device detection working)
- **Risk Level:** 🔴 HIGHEST - Monitor closely. Any delay compounds to final timeline.

**Wave 3 Gap 5.8:** Queued
- Task: Not starting until T+60 (no blocker)
- Status: Staged and ready
- Expected: Waiting

## CRITICAL PATH: GAP 5.7 DEEP DIVE

**Task #21: Implement GPU Compute Shaders (WebGPU + WebGL GPGPU)**
**Owner:** api-performance-implementer
**Timeline:** 40 minutes total (T+40 → T+80)

### Phase 1 Breakdown (T+40 → T+52, 12 minutes)

**What Should Happen at T+45-50:**
1. Create `useGPUCompute.ts` hook
   - Device detection logic
   - Fallback to CPU if no GPU
   - Expected: File exists, TS compiles (may have runtime warnings)

2. Create `force-directed.wgsl` shader
   - Fruchterman-Reingold algorithm in WebGPU
   - Buffer bindings: nodes, edges, forces
   - Expected: WGSL file compiles without errors

3. Basic integration test
   - Can create GPU device
   - Can compile shader
   - Can run small test (10 nodes)
   - Expected: No async errors, device logs OK

### Risk Assessment

**Green Flags (No Action Needed):**
- Files created and compiling
- Device detection working
- No TS errors in codebase
- Progress reports being sent

**Yellow Flags (Monitor Closely):**
- WebGPU APIs not fully understood → expected, ask for clarification
- WGSL syntax errors in shader → encourage iterative fixing
- Device detection failing on test system → document and move to fallback (WebGL)
- Runtime errors in device creation → fixable, escalate for brainstorming

**Red Flags (Escalate Immediately):**
- Complete radio silence (no messages T+45-T+60)
- "Stuck on WGPU syntax" with no progress for 10+ min
- GPU code blocks other gaps (should not happen - independent execution)
- Multiple TS compilation errors from GPU files

### Checkpoint 2.5 Action if Gap 5.7 is Behind

**If Gap 5.7 is <40% at T+50:**
1. Send message to api-performance-implementer: "Gap 5.7 progress check - Status update?"
2. Offer specific help from plan docs (lines with code sketches)
3. Consider: Can WebGL fallback start in parallel?
4. Monitor with 5-minute checkpoints through T+60

**If Gap 5.7 is 40-60% at T+50:**
- On track, continue monitoring
- Note: Gap 5.7 determines overall completion time

**If Gap 5.7 is >60% at T+50:**
- Ahead of schedule ✅
- Likely completion T+75-78 (vs T+80 estimate)

**Expected Progress:** Waiting

**Status:** Staged for T+60 start, no blockers

## MONITORING PROTOCOL: HOW TO SPOT ISSUES

### Silent Failure Pattern (Most Dangerous)
**What it looks like:** Tasks show in_progress but no activity
- **Check:** git diff - are files being modified?
- **Action:** Message the agent "Gap X progress check - status update?"
- **Escalate if:** No response after 5 minutes

### Compilation Block Pattern
**What it looks like:** Agent says "Can't compile" or "TS error"
- **Check:** What's the error? (usually simple import, type issue)
- **Action:** Reference implementation plan with code sketch
- **Escalate if:** >3 back-and-forth attempts, still stuck

### Timing Slip Pattern
**What it looks like:** Gap 5.7 takes >15 min for Phase 1 setup
- **Check:** How much of Phase 1 is complete at T+50?
- **Action:** Encourage parallel work (WebGL while WebGPU compiles)
- **Escalate if:** <30% done by T+50

### Cross-Gap Blocker Pattern
**What it looks like:** "Gap X depends on Gap Y finishing"
- **Check:** Is this a real dependency? (Usually no for Gaps 5.3-5.8)
- **Action:** Clarify that gaps are independent, unblock immediately
- **Escalate if:** Real architectural dependency discovered

## COORDINATOR ACTIONS AT T+50 CHECKPOINT

### Validation (5 minutes)
```
1. Count passing tests across all gaps
   - Expected: 8+ tests (minimal) to 12+ tests (good)
   - If <8: Alert and investigate which gap is lagging

2. Check Gap 5.7 status specifically
   - If <40% Phase 1: Message api-performance-implementer
   - If 40-70%: On track, monitor
   - If >70%: Ahead, great progress

3. Verify no git conflicts
   - Run: git status --short
   - If conflicts, notify user immediately

4. Verify TS/Go/Python compilation
   - Frontend: bun run build (sample)
   - Backend: go build ./internal/temporal
   - Python: python3 -m py_compile
```

### If Everything On Track: Celebrate! Send acknowledgments
```
🎉 "Checkpoint 2.5 ON TRACK - Wave 2 Phase 2-3 proceeding, Wave 3 Phase 1 active.
   Gap 5.7 critical path on schedule (>50% Phase 1 complete by T+50).
   Continue to Checkpoint 3 at T+55. Excellent execution. 👍"
```

### If Gaps are Slipping: Escalate Blockers
```
⚠️ "Checkpoint 2.5 ALERT - [Gap X] behind schedule ([N]% Phase [Y] at T+50, expected [N]%).
   Investigating root cause and offering targeted support.
   [Specific help offered or blocker question].
   Next check: T+55 Checkpoint 3."
```
