## 📋 Unified Best Practices

### Core Principles

1. **Multi-Dimensional Evaluation**
   - Don't rely on single satisfaction score
   - Track: helpfulness, accuracy, clarity, safety, engagement

2. **Implicit + Explicit Feedback**
   - **Explicit**: User ratings, comments, corrections
   - **Implicit**: Regenerations, follow-ups, time patterns, edits

3. **Context-Aware Analysis**
   - Consider conversation history
   - Domain/task-specific evaluation
   - User preference learning

4. **Real-Time & Batch Processing**
   - Real-time: Quick satisfaction signals
   - Batch: Deep semantic analysis

5. **Privacy & Security**
   - Anonymize sensitive feedback
   - Secure storage
   - User consent for AI analysis

## 🎨 Recommended Design

### 1. **Feedback Taxonomy**

```python
class FeedbackType(Enum):
    # Explicit
    RATING = "rating"                    # 1-5 stars or thumbs
    CORRECTION = "correction"            # User corrects AI
    COMPLAINT = "complaint"              # Issue report
    APPRECIATION = "appreciation"        # Positive feedback
    
    # Implicit
    REGENERATION = "regeneration"        # User asks for new response
    CLARIFICATION = "clarification"      # Follow-up question
    ABANDONMENT = "abandonment"          # User leaves
    EDIT = "edit"                        # User edits AI response
```

### 2. **Multi-Dimensional Scoring**

```python
@dataclass
class FeedbackScore:
    # Primary dimensions (inspired by Claude)
    helpfulness: float       # 0.0-1.0
    accuracy: float          # 0.0-1.0
    clarity: float           # 0.0-1.0
    safety: float            # 0.0-1.0
    
    # Secondary dimensions
    completeness: float      # 0.0-1.0
    efficiency: float        # 0.0-1.0
    engagement: float        # 0.0-1.0 (inspired by Grok)
    
    # Meta
    confidence: float        # 0.0-1.0
    timestamp: datetime
```

### 3. **Signal Collection (ChatGPT-style)**

```python
@dataclass
class ImplicitSignals:
    # Timing signals
    time_to_first_response: float        # Seconds
    time_between_messages: float         # Seconds
    session_duration: float              # Seconds
    
    # Interaction signals
    regeneration_count: int              # Times user asked to regenerate
    edit_count: int                      # Times user edited AI response
    copy_count: int                      # Times user copied content
    
    # Navigation signals
    scroll_depth: float                  # 0.0-1.0
    revisit_count: int                   # Times user came back
    abandonment: bool                    # Did user leave mid-conversation
```

### 4. **Grounding Verification (Gemini-style)**

```python
@dataclass
class GroundingFeedback:
    claims_made: int
    claims_verified: int
    sources_cited: int
    factual_accuracy: float      # 0.0-1.0
    citation_quality: float      # 0.0-1.0
```

### 5. **Aggregation Patterns**

```python
class FeedbackAggregator:
    def aggregate_session(self, session_id: str) -> SessionMetrics:
        """Aggregate feedback for single session"""
        
    def aggregate_temporal(self, time_window: str) -> TemporalMetrics:
        """Aggregate across time (hourly, daily, weekly)"""
        
    def aggregate_by_dimension(self, dimension: str) -> DimensionMetrics:
        """Analyze specific dimension across sessions"""
        
    def detect_patterns(self) -> List[Pattern]:
        """Detect trends, anomalies, improvements"""
```
