"""
Observability and analytics response models for Brokle SDK.

This module contains response models for observability, tracing, and analytics:
- ObservabilityTraceResponse
- ObservabilityObservationResponse
- ObservabilityQualityScoreResponse
- ObservabilityStatsResponse
- ObservabilityListResponse
- ObservabilityBatchResponse
- AnalyticsResponse
- EvaluationResponse

Models are refactored to use mixins for reduced duplication while maintaining
complete backward compatibility.
