# TaskExtensions

`TaskExtensions` is a static extension-method class that centralizes the task priority and source code sets so every task list screen maps the same codes to the same display values.

| Field | Value |
| --- | --- |
| **Operation ID** | OP-CORE-05 |
| **Trigger** | Task list mapping/display |
| **Inputs** | Task priority code, task source code |
| **Outputs** | Display value for the code |
| **Primary components** | `TaskExtensions` |
| **Entry point** | `Core/SAIF.Core/Contracts/Tasks/Extensions/TaskExtensions.cs` |

## Steps

1. An extension method maps a task priority code — URG, INFO, MED, LOW, or HIGH — to its display value ([CORE-BR-040](../business-rules.md#core-br-040-task-priority-codes-are-urg-info-med-low-high-source-codes-are-claim-coll-covb-image-wcis-rtw)).
2. A second extension method maps a task source code — CLAIM, COLL, COVB, IMAGE, WCIS, or RTW — to its display value ([CORE-BR-040](../business-rules.md#core-br-040-task-priority-codes-are-urg-info-med-low-high-source-codes-are-claim-coll-covb-image-wcis-rtw)).
3. The mapped display value is returned to the caller for rendering in a task list.

## Failure and edge-case behavior
- An unrecognized code's mapping behavior is not verified in this contract*.
