# PolicyPeriodGroupAssoc

Domain entity representing Policy period group assoc data within the policies area of the claims/policy domain, mapped for NHibernate persistence.*

## Purpose
- Models policy period group assoc data used by the policies area of this library.*
- Inherits shared identity/lifecycle behavior from `EntityBase`.

## Context
- Namespace: `SAIF.Data.Model.Policies`
- Assembly/package: `SAIF.Data`

## Behavioral notes
- Properties are typically declared `virtual` to support NHibernate lazy-loading proxies (see the corresponding mapping file under `Data/SAIF.Data.NHibernate`).*

## Constraints and usage notes
- No additional usage constraints beyond standard NHibernate entity/DTO conventions could be confirmed from static analysis.**

> **Note:** Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
