   - **After:** 4 outputs, 295 lines, advanced features
   - **New Features:**
     - ⏱️ Time tracking (operating time & downtime)
     - 💾 State backup to database (every 10 cycles)
     - 🔢 Cycle count capping at 100 with warnings
     - 📊 Anomaly detection for irregular cycle times

   - **Before:** 4 outputs, 120 lines
   - **After:** 5 outputs, 350 lines
   - **New Features:**
     - 🛑 Stop reason categorization (planned vs unplanned)
     - 📝 Session management (creates sessions on START/RESUME)
     - 🔄 Session tracking with metadata
     - ⏹️ Stop event logging

#### 3. **New MySQL Nodes Added** (3 nodes)
   - **State Backup DB** - Saves session state every 10 cycles
   - **Anomaly Tracker DB** - Logs irregular cycle times
   - **Session Manager DB** - Tracks production sessions

#### 4. **Startup Recovery Flow** (New Tab)
   - Automatically checks for crashed sessions on startup
   - Runs 5 seconds after Node-RED starts
   - Restores session state from database
   - **Location:** New "Startup Recovery" tab in Node-RED

#### 5. **Stop Reason UI Template** (New Node)
   - Modal dialog for stop categorization
   - 4 planned stop options (lunch, break, shift change, maintenance)
   - 5 unplanned stop options (malfunction, shortage, quality, error, other)
   - **Location:** Added to Home dashboard

## 🚀 Next Steps - TESTING

### Step 1: Restart Node-RED

```bash
# Stop Node-RED
pm2 stop node-red  # or however you run it

# Start Node-RED
pm2 start node-red
```

Or use the Node-RED restart option in the editor.

### Step 2: Verify Startup

After Node-RED restarts:

1. **Check for errors** in the Node-RED log/console
2. **Look for this message:** `[RECOVERY] Checking for existing session state...`
   - This means startup recovery is working
3. **Open Node-RED editor** and verify:
   - New tab "Startup Recovery" appears
   - Machine cycles node shows 4 outputs
   - Work Order buttons node shows 5 outputs
   - 3 new MySQL nodes visible

### Step 3: Basic Functionality Test

1. **Start a work order**
2. **Click START button**
3. **Let machine run 2-3 cycles**
4. **Check session_state table:**
   ```sql
   SELECT * FROM session_state WHERE session_key = 'current_session';
   ```
   - Should show cycle_count > 0
   - Should show operating_time increasing
   - tracking_enabled should = 1

### Step 4: Stop Reason Test

1. **Click STOP button**
2. **Verify:** Modal dialog appears with stop reason options
3. **Select** a planned stop (e.g., "Lunch break")
4. **Click Submit**
5. **Check stop_events table:**
   ```sql
   SELECT * FROM stop_events ORDER BY id DESC LIMIT 1;
   ```
   - Should show your stop with affects_availability = 0

### Step 5: Resume Test

1. **Click START again** (RESUME)
2. **Check production_sessions table:**
   ```sql
   SELECT * FROM production_sessions ORDER BY start_time DESC LIMIT 2;
   ```
   - Should show 2 sessions (original and resumed)

### Step 6: Cycle Cap Test

1. **Manually set cycle count to 95:**
   ```javascript
   // In Node-RED debug console or inject node:
   global.set("cycleCount", 95);
   ```
2. **Run 5 more cycles**
3. **At cycle 100:** Should see alert "Maximum 100 cycles reached"

## 🐛 Troubleshooting

### Issue: Node-RED won't start
**Symptom:** Errors about invalid JSON or syntax errors
**Solution:**
```bash
# Restore backup
cp /home/mdares/.node-red/flows.json.backup_20251121_185206 /home/mdares/.node-red/flows.json
# Restart Node-RED
```

### Issue: "Table doesn't exist" errors in MySQL nodes
**Symptom:** MySQL errors about missing tables
**Solution:** Re-run the migration SQL in Beekeeper (you may have missed a table)

### Issue: Stop reason prompt doesn't show
**Symptom:** Clicking STOP doesn't show modal
**Solution:** Check browser console (F12) for JavaScript errors. The UI template may need adjustment.

### Issue: Time tracking not working
**Symptom:** operating_time and downtime stay at 0
**Solution:**
1. Verify trackingEnabled is true: `global.get("trackingEnabled")`
2. Check Machine cycles function is receiving inputs
3. Verify state backup is running (check debug log every 10 cycles)

## 🎯 Success Metrics

Monitor these after deployment:

1. **Zero crashes lose data** ✓
2. **Planned stops don't affect availability** ✓
3. **100 cycle cap prevents overruns** ✓
4. **Anomalies automatically logged** ✓
5. **Session patterns visible in database** ✓
