# EaipPeriod

Model type representing Eaip period data within the eaip area of the claims/policy domain, mapped for NHibernate persistence.*

## Purpose
- Models eaip period data used by the eaip area of this library.*
- Inherits shared identity/lifecycle behavior from `IDataEntity`.

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

| ActivityDate | `DateTime ActivityDate { get; set; }` | Date/time value for activity date.* |
| EaipUser | `string EaipUser { get; set; }` | Value of eaip user exposed by this type.* |
| EffectiveDate | `DateTime EffectiveDate { get; set; }` | Date/time value for effective date.* |
| ExpirationDate | `DateTime ExpirationDate { get; set; }` | Date/time value for expiration date.* |
| EaipStatusDate | `DateTime EaipStatusDate { get; set; }` | Date/time value for eaip status date.* |

## 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.
