# 🎉 What's New in v2.0 - Auto-Remediation & Feedback System

## 🚀 Major New Features

### 1️⃣ Auto-Remediation (Write Operations) ⚠️

**AI can now automatically fix problems** by executing write operations on your infrastructure.

#### Key Points:
- ✅ **DEFAULT: DISABLED** - Must explicitly enable per ticket for safety
- ✅ **Smart Decision Engine** - Only executes when confidence is high
- ✅ **Safety Checks** - Pre/post validation, backups, rollbacks
- ✅ **Approval Workflow** - Critical actions require human approval
- ✅ **Full Audit Trail** - Every action logged

#### Example Usage:

```python
# Submit ticket WITH auto-remediation
{
    "ticket_id": "INC-001",
    "description": "Web service not responding",
    "category": "server",
    "enable_auto_remediation": true  # ← Enable write operations
}

# AI will:
# 1. Analyze the problem
# 2. Check reliability score
# 3. If score ≥85% and safe action → Execute automatically
# 4. If critical action → Request approval
# 5. Log all actions taken
```

**What AI Can Do:**
- Restart services/VMs
- Clear caches
- Scale deployments
- Enable network ports
- Expand storage volumes
- Rollback deployments

**Safety Guardrails:**
- Minimum 85% reliability required
- Rate limiting (max 10 actions/hour)
- Time windows (maintenance hours only)
- Backup verification
- System health checks
- Rollback on failure

---

### 2️⃣ Reliability Scoring System 📊

**Multi-factor confidence calculation** that gets smarter over time.

#### How It Works:

```
Reliability Score (0-100%) = 
  AI Confidence        × 25% +  # Claude's confidence
  Human Feedback       × 30% +  # User ratings & feedback
  Historical Success   × 25% +  # Past resolution success rate
  Pattern Recognition  × 20%    # Similarity to known issues
```

#### Confidence Levels:

| Score | Level | Action |
|-------|-------|--------|
| 90-100% | 🟢 Very High | Auto-execute without approval |
| 75-89% | 🔵 High | Auto-execute or require approval |
| 60-74% | 🟡 Medium | Require approval |
| 0-59% | 🔴 Low | Manual resolution only |

#### Example:

```json
{
  "reliability_score": 87.5,
  "confidence_level": "high",
  "breakdown": {
    "ai_confidence": "92%",
    "human_validation": "85%", 
    "success_history": "90%",
    "pattern_recognition": "82%"
  }
}
```

### 3️⃣ Human Feedback Loop 🔄

**Your feedback makes the AI smarter.**

#### What You Can Provide:

```javascript
{
  "ticket_id": "INC-001",
  "feedback_type": "positive|negative|neutral",
  "rating": 5,  // 1-5 stars
  "was_helpful": true,
  "resolution_accurate": true,
  "actions_worked": true,
  
  // Optional details
  "comment": "Perfect! Service is back up.",
  "what_worked": "The service restart fixed it",
  "what_didnt_work": null,
  "suggestions": "Could add health check step",
  
  // If AI failed, what actually worked?
  "actual_resolution": "Had to increase memory instead",
  "time_to_resolve": 30.0  // minutes
}
```

#### Impact of Feedback:

1. **Immediate**: Updates reliability score for that ticket
2. **Pattern Learning**: Strengthens/weakens similar issue handling
3. **Future Decisions**: Influences auto-remediation eligibility
4. **System Improvement**: Better resolutions over time

---

### 4️⃣ Pattern Learning & Recognition 🧠

**AI learns from repeated issues** and gets better at handling them.

#### How Patterns Work:

```
Issue occurs first time:
└─ Manual resolution, collect feedback

After 5+ similar issues with good feedback:
├─ Pattern identified and eligible for auto-remediation
├─ Success rate: 85%+
└─ Can auto-fix similar issues in future

After 20+ occurrences:
├─ Very high confidence (90%+)
├─ Success rate: 92%+
└─ Auto-fix without approval (if safe action)
```

#### Pattern Eligibility Criteria:

```python
eligible_for_auto_remediation = (
    occurrence_count >= 5 AND
    positive_feedback_rate >= 0.85 AND
    avg_reliability_score >= 85.0 AND
    auto_remediation_success_rate >= 0.85
)
```

## 📊 Example Workflow

### Traditional Flow (v1.0)
```
1. User submits ticket
2. AI analyzes and suggests resolution
3. User manually executes actions
4. Done
```

### Enhanced Flow (v2.0)
```
1. User submits ticket with auto_remediation=true
2. AI analyzes problem
3. AI calculates reliability score
4. Decision Engine evaluates:
   ├─ High confidence + safe action → Execute automatically
   ├─ Medium confidence → Request approval
   └─ Low confidence → Manual resolution only
5. If approved/auto-approved:
   ├─ Pre-execution safety checks
   ├─ Execute actions via MCP
   ├─ Post-execution validation
   └─ Log all actions
6. User provides feedback
7. System learns and improves
8. Future similar issues → Faster, smarter resolution
```

## 🎯 Use Cases

### Use Case 1: Service Down

```python
# Ticket: "Web service not responding"
# Category: server
# Auto-remediation: enabled

AI Analysis:
├─ Identifies: Service crash
├─ Solution: Restart service
├─ Reliability: 92% (based on 15 similar past issues)
├─ Action type: safe_write
└─ Decision: Auto-execute without approval

Result:
├─ Service restarted in 3 seconds
├─ Health check: passed
├─ Action logged
└─ User feedback: ⭐⭐⭐⭐⭐

Future:
└─ Similar issues auto-fixed with 95% confidence
```

### Use Case 2: Storage Full

```python
# Ticket: "Datastore at 98% capacity"
# Category: storage
# Auto-remediation: enabled

AI Analysis:
├─ Identifies: Storage capacity issue
├─ Solution: Expand volume by 100GB
├─ Reliability: 88%
├─ Action type: critical_write (expansion can't be undone easily)
└─ Decision: Require approval

Workflow:
├─ Approval requested from admin
├─ Admin reviews and approves
├─ Pre-check: Backup verified
├─ Volume expanded
├─ Post-check: New space available
└─ Logged with approval trail

Future:
└─ After 10+ successful expansions, may auto-approve
```

### Use Case 3: Network Port Flapping

```python
# Ticket: "Port Gi0/1 flapping on switch"
# Category: network
# Auto-remediation: enabled

AI Analysis:
├─ Identifies: Interface errors causing flapping
├─ Solution: Clear interface errors, bounce port
├─ Reliability: 78% (only 3 similar past issues)
├─ Pattern: Not yet eligible for auto-remediation
└─ Decision: Require approval (not enough history)

After 5+ similar issues with good feedback:
└─ Pattern becomes eligible
└─ Future port issues auto-fixed
```

### New Defaults:

- `enable_auto_remediation: false` (explicit opt-in required)
- `requires_approval: true` (by default)
- `min_reliability_score: 85.0`

### Database Migration:

```bash
# Run Alembic migrations
poetry run alembic upgrade head

# Migrations add new tables:
# - ticket_feedbacks
# - similar_tickets
# - remediation_logs
# - auto_remediation_policies
# - remediation_approvals
# - ticket_patterns
```
