## Deployment Steps

### Step 1: Prepare Environment
```bash
# 1a. Ensure you're on the correct branch
git branch -vv
# Expected: 1177-feature-phase-based-assignee-pipeline

# 1b. Verify changes
git diff main...HEAD worklenz-backend/src/socket.io/commands/on-task-phase-change.ts
# Should show the removal logic added

# 1c. Check git status
git status
# Should be clean
```

### Step 2: Build Backend
```bash
# 2a. Install dependencies (if needed)
cd worklenz-backend
npm install

# 2b. Compile TypeScript
npm run build
# Expected output: No errors

# 2c. Check for lint errors
npm run lint
# Expected output: No errors in on-task-phase-change.ts
```

### Step 3: Unit Testing (Optional)
```bash
# 3a. Run existing tests
npm run test

# 3b. Verify no regressions
# Expected: All tests pass
```

### Step 4: Deploy to Staging
```bash
# 4a. Push to staging branch
git push origin 1177-feature-phase-based-assignee-pipeline:staging

# 4b. Deploy staging container
# (Use your deployment process)

# 4c. Verify backend is running
curl http://staging-backend:3000/health
# Expected: 200 OK
```

### Step 5: Deploy to Production
```bash
# 5a. Create Pull Request
gh pr create --base main --head 1177-feature-phase-based-assignee-pipeline

# 5b. Get code review approval
# (Ensure team reviews)

# 5c. Merge to main
# (After approval)

# 5d. Deploy production
# (Use your deployment process)

# 5e. Monitor logs
# (Watch for any errors)
```

---

## Post-Deployment Verification

### Immediate Checks (First Hour)

#### Backend Logs
```bash
# Check for any errors
tail -f logs/backend.log | grep -i "error"

# Look for successful auto-assignments
tail -f logs/backend.log | grep "\[Phase Auto-Assign\]"
# Expected: See removal and assignment messages
```

#### Socket Connection
```javascript
// In browser console on staging
socket.on(SocketEvents.QUICK_ASSIGNEES_UPDATE, (data) => {
  console.log("Assignee update:", data);
});
// Try moving a task between phases
```

#### API Response
```bash
# Test phase change endpoint
curl -X POST http://localhost:3000/api/v1/task-phases/change \
  -H "Content-Type: application/json" \
  -d '{"task_id": "xyz", "phase_id": "abc"}'
# Expected: 200 OK with phase change response
```

### Functional Tests (Day 1)

#### Test Case 1: Basic Auto-Assignment
1. [ ] Create project with 2 phases
2. [ ] Set different default assignees for each phase
3. [ ] Enable `phase_assignees_enabled`
4. [ ] Create task in Phase A
5. [ ] Task should have Phase A's assignee ✓
6. [ ] Move task to Phase B (drag-drop)
7. [ ] Phase A assignee should be removed ✓
8. [ ] Phase B assignee should be assigned ✓
9. [ ] Check real-time update in UI ✓

#### Test Case 2: Multiple Assignees
1. [ ] Create task with Phase A assignee
2. [ ] Add another team member manually
3. [ ] Task should have 2 assignees
4. [ ] Move to Phase B
5. [ ] Phase A assignee removed ✓
6. [ ] Phase B assignee added ✓
7. [ ] Manual assignee remains ✓
8. [ ] Total: 2 assignees ✓

#### Test Case 3: No Phase Default
1. [ ] Move to phase with NO default assignee
2. [ ] Current assignees should NOT be removed ✓
3. [ ] No new assignee added ✓
4. [ ] Task unchanged except phase ✓

#### Test Case 4: Real-Time Updates
1. [ ] Open task board in two browser windows
2. [ ] Move task in window 1
3. [ ] Window 2 should update automatically ✓
4. [ ] No page refresh needed ✓
5. [ ] Assignee avatar updates instantly ✓

#### Test Case 5: Drag-Drop
1. [ ] Use kanban board drag-drop
2. [ ] Drop task on new phase
3. [ ] Auto-assignment should trigger ✓
4. [ ] Same behavior as dropdown ✓

#### Test Case 6: Feature Disabled
1. [ ] Disable `phase_assignees_enabled`
2. [ ] Move task between phases
3. [ ] No auto-assignment should happen ✓
4. [ ] Manual assignment still works ✓

### Data Integrity Checks

#### Task Assignments Table
```sql
-- Verify no orphaned records
SELECT ta.* 
FROM task_assignees ta
LEFT JOIN tasks t ON t.id = ta.task_id
WHERE t.id IS NULL;
-- Expected: 0 rows

-- Check for duplicate assignments
SELECT task_id, team_member_id, COUNT(*)
FROM task_assignees
GROUP BY task_id, team_member_id
HAVING COUNT(*) > 1;
-- Expected: 0 rows
```

#### Task Phase Table
```sql
-- Verify phase references are valid
SELECT tp.* 
FROM task_phase tp
LEFT JOIN project_phases pp ON pp.id = tp.phase_id
WHERE pp.id IS NULL AND tp.phase_id IS NOT NULL;
-- Expected: 0 rows
```

#### Task Updates
```sql
-- Check updated_at timestamps are recent
SELECT COUNT(*) as recent_updates
FROM tasks
WHERE updated_at > NOW() - INTERVAL '1 hour'
AND updated_at < NOW();
-- Expected: > 0 (verifies updates are being logged)
```

### Performance Checks

#### Database Performance
```bash
# Check slow query log
grep "Phase Auto" /var/log/mysql/slow.log
# Expected: No entries (queries should be fast)

# Check query execution time
# Should be < 50ms for most queries
```

#### Socket Performance
```javascript
// In browser console
const start = performance.now();
// Move a task between phases
// Watch for QUICK_ASSIGNEES_UPDATE
// Expected: < 200ms roundtrip
```

#### API Response Time
```bash
# Measure API response time
time curl -X POST http://localhost:3000/api/v1/task-phases/change \
  -H "Content-Type: application/json" \
  -d '{"task_id": "xyz", "phase_id": "abc"}'
# Expected: real < 1s
```

### Monitoring (Week 1)

#### Error Tracking
```bash
# Search for phase auto-assign errors
grep "Error in autoAssignPhaseAssignee" logs/backend.log
# Expected: 0 errors

# Check for unhandled exceptions
grep -i "uncaught\|unhandled" logs/backend.log
# Expected: No phase-related errors
```

#### Usage Metrics
```sql
-- Track feature usage
SELECT 
  DATE(t.updated_at) as date,
  COUNT(*) as phase_changes
FROM tasks t
WHERE t.updated_at > NOW() - INTERVAL '7 days'
GROUP BY DATE(t.updated_at)
ORDER BY date;
-- Expected: Positive numbers showing feature is being used
```

#### User Reports
- [ ] No user complaints about missing assignees
- [ ] No reports of duplicate assignments
- [ ] No unexpected assignment changes
- [ ] Feature working as expected

---

## Rollback Plan

If issues are discovered:

### Option 1: Quick Revert (Git)
```bash
# Revert the commit
git revert e0d5e053
git push origin main

# Redeploy previous version
# (Use your deployment process)

# Verify revert
git log -1 --oneline
# Expected: Shows revert commit
```

### Option 2: Feature Flag Disable
```sql
-- Disable the feature temporarily
UPDATE projects SET phase_assignees_enabled = false;

-- Monitor for 1 hour
-- If all stable, investigate issue

-- Re-enable after fix
UPDATE projects SET phase_assignees_enabled = true;
```
