    def __init__(self):
        self.model = self._load_model()
        self.features = [
            'issue_age', 'comment_count', 'reaction_count',
            'author_contributions', 'label_severity',
            'linked_prs', 'mention_count', 'activity_trend'
        ]
    
    def score(self, item):
        features = self._extract_features(item)
        priority = self.model.predict(features)
        confidence = self.model.predict_proba(features)
        return {
            'score': priority,
            'confidence': confidence,
            'factors': self._explain_score(features)
        }

    def get(self, key):
        # Record access for pattern learning
        self.access_patterns.append((time.time(), key))
        
        if key in self.cache:
            # Check if likely stale using ML
            staleness_prob = self.predictor.predict_staleness(key)
            if staleness_prob < 0.3:  # 30% threshold
                return self.cache[key]
        
        # Fetch fresh data
        data = self._fetch(key)

        doc = self.nlp(text)
        entities = [ent.text for ent in doc.ents]
        
        # Semantic similarity to repository topics
        text_embedding = self.vectorizer.encode(text)
        context_embedding = self.vectorizer.encode(context)
        similarity = cosine_similarity(text_embedding, context_embedding)
        
        # Detect urgency signals
