"""
Thread domain models for Mail Intake.
This module defines the **canonical, provider-agnostic representation**
of an email thread as used internally by the Mail Intake ingestion pipeline.
Threads group related messages and serve as the primary unit of reasoning
for higher-level correspondence workflows.
