## New Feature: AI-Mining Quality Scoring v2
 
### Overview
Brief description of the feature...
 
### Usage Example
```rust
let scorer = QualityScorer::new(ScorerConfig::default());
let score = scorer.calculate_score(&task_result)?;

### 6. Commit Messages

**Commit Message Format**:

**Types**:
- `feat`: New feature
- `fix`: Bug fix

// Example: Secure input validation
pub fn validate_transaction_amount(amount: u64) -> Result<(), ValidationError> {
    // Check for overflow
    if amount > MAX_TRANSACTION_AMOUNT {
        return Err(ValidationError::AmountTooLarge);
