## 🛠️ **Enhanced Integration Framework**

### **1. Schema Enhancements**
Updated `core-ia-components-schema-robust.json` with:

```json
{
  "binding": {
    "type": {
      "enum": ["property", "expr", "tag", "expr-struct", "query", "tag-history"]
    },
    "transforms": {
      "items": {
        "type": {
          "enum": ["map", "script", "expression", "format"]
        }
      }
    }
  }
}
```

### **2. Linter Enhancements**
Added comprehensive binding validation:

- **Binding Type Validation:** Ensures only empirically-validated binding types
- **Configuration Validation:** Validates required properties per binding type
- **Transform Validation:** Checks transform types and required properties
- **Best Practice Checks:** Fallback handling, error handling patterns

### **3. Agent Integration Tools**

#### **CLI Tool (`./ignition-lint`)**
```bash
./ignition-lint path/to/view.json --format=json --severity=warning
```
Returns structured JSON for agent consumption.

#### **Pre-commit Hook**
```yaml
- id: ignition-perspective-lint
  entry: ./ignition-lint
  language: python
  files: '\.json$'
```

#### **LSP Server (`ignition-lsp-server.py`)**
Real-time binding validation in IDEs.

## 📋 **Binding Validation Rules**

### **Tag Binding Validation**
```python
# REQUIRED: tagPath property
if 'tagPath' not in config:
    ERROR: "Tag binding missing required 'tagPath'"

# RECOMMENDED: Fallback handling
if prop_name in critical_props and 'fallbackDelay' not in config:
    INFO: "Consider adding fallback handling"
```

### **Expression Binding Validation**  
```python
# REQUIRED: expression property
if 'expression' not in config:
    ERROR: "Expression binding missing required 'expression'"
```

### **Property Binding Validation**
```python
# REQUIRED: path property
if 'path' not in config:
    ERROR: "Property binding missing required 'path'"
```

### **Transform Validation**
```python
# Map transforms
if transform_type == 'map':
    if 'mappings' not in transform:
        WARNING: "Map transform missing 'mappings' array"
    if 'fallback' not in transform:
        INFO: "Consider adding fallback value"

# Script transforms  
if transform_type == 'script' and 'code' not in transform:
    ERROR: "Script transform missing 'code' property"
```

## 🎯 **AI Development Guidelines**

### **Binding Selection Pattern**
```python
def select_binding_type(data_source, complexity):
    if data_source == "static_params":
        return "property"
    elif data_source == "plc_tags":
        return "tag" 
    elif complexity == "simple_calc":
        return "expr"
    elif complexity == "complex_logic":
        return "expr" + "script_transform"
```

### **Common Patterns by Usage**

#### **Most Common Expression Patterns (47.2% of bindings)**
```javascript
// Conditional logic (most common)
if({[Tank01]Level} > 75, 'HIGH', if({[Tank01]Level} > 25, 'MEDIUM', 'LOW'))

// String concatenation 
'Tank Level: ' + {[Tank01]Level} + '%'

// Quality checking
if({tag.quality} = 'Good', {tag.value}, 'Bad Quality')
```

#### **Most Common Property Patterns (33.2% of bindings)**
```json
{
  "type": "property",
  "config": {
    "path": "view.params.tankId"  // Most common path pattern
  },
  "transforms": [
    {
      "type": "expression", 
      "expression": "'Tank: ' + {value}"  // Common transform
    }
  ]
}
```

#### **Most Common Tag Patterns (18.6% of bindings)**
```json
{
  "type": "tag",
  "config": {
    "tagPath": "[Production]Line01/Tank/Level",
    "mode": "direct",           // Most common mode
    "fallbackDelay": 2.5        // Best practice
  }
}
```

### **Transform Usage Guidelines**

#### **Use Map Transforms (70.9%) For:**
- Status colors: `0 → "#FF0000"`, `1 → "#00FF00"`
- State text: `0 → "Stopped"`, `1 → "Running"`
- Alarm levels: `1 → "Critical"`, `2 → "Warning"`

#### **Use Script Transforms (19.9%) For:**
- Complex calculations with multiple inputs
- Mode switching based on screen size
- Integration with external systems
- Custom formatting beyond standard options
