# IncurredCostHistory

Domain entity representing Incurred cost history data within the claims reserves area of the claims/policy domain, mapped for NHibernate persistence.*

## Purpose
- Models incurred cost history data used by the claims reserves area of this library.*
- Inherits shared identity/lifecycle behavior from `EntityBase`.

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

| ClaimCostDate | `DateTime ClaimCostDate { get; set; }` | Date/time value for claim cost date.* |
| ReserveApproverUser | `string ReserveApproverUser { get; set; }` | Value of reserve approver user exposed by this type.* |
| ReserveInitiatorUser | `string ReserveInitiatorUser { get; set; }` | Value of reserve initiator user exposed by this type.* |

| AddCategoryCost | `void AddCategoryCost(IncurredCategoryCost categoryCost)` | Adds category cost.* |
| IncurredCostHistory() | `IncurredCostHistory()` | Initializes a new instance of the type with the supplied dependencies.* |

## 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.
