# ClaimDisabilityActivity

Domain entity representing Claim disability activity data within the claims area of the claims/policy domain, mapped for NHibernate persistence.*

## Purpose
- Models claim disability activity data used by the claims area of this library.*
- Inherits shared identity/lifecycle behavior from `EntityBase`.

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

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| Id | `int Id { get; set; }` | Primary key / surrogate identifier for this record.* |
| Claim | `InjuryClaim Claim { get; set; }` | Reference to the associated `InjuryClaim` record.* |
| DisabilityDate | `DateTime? DisabilityDate { get; set; }` | Date/time value for disability date.* |
| UpdateUser | `string UpdateUser { get; set; }` | Value of update user exposed by this type.* |
| UpdateNumber | `int UpdateNumber { get; set; }` | Value of update number exposed by this type.* |

## 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.
