"""Observability emission models and cardinality policies.

This module provides models for metrics emission, log emission,
and cardinality policy enforcement for the ONEX observability stack.

Metrics Emission Models:
    - ModelCounterEmission: Counter metric increments
    - ModelGaugeEmission: Gauge metric values
    - ModelHistogramObservation: Histogram observations

Log Emission:
    - ModelLogEmission: Structured log entries with severity

Cardinality Policy:
    - ModelMetricsPolicy: Label validation and cardinality enforcement
    - ModelLabelViolation: Individual policy violation details
    - ModelLabelValidationResult: Complete validation result with sanitization
