# NodeHelper

Provides a single static factory that converts a `Worker` domain model into a `ContactItem` for the Claim Information API, copying email, address, and name, and attaching the worker's primary and message phone numbers when present.

## Purpose
- Produces a consistent `ContactItem` representation of a worker (email, address, formatted name) for use across node builders that need to display worker contact information.
- Attaches primary and message phone numbers to the contact only when they are set on the worker.

## Context
- Namespace: `SAIF.Services.Claims.Information.Api`
- Assembly/package: `SAIF.Services` (packaged inside the `SAIF.SAIFCode.Core` NuGet package)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| BuildWorkerContact(worker) | `public static ContactItem BuildWorkerContact(Worker worker)` | Builds and returns a `ContactItem` populated with the worker's email, address, name, and formatted first-name-first display name, adding primary and message phone numbers when they exist on the worker. |

## Behavioral notes
- The method assumes `worker` is non-null (guarded only by a code-analysis suppression, not a runtime null check).

## Constraints and usage notes
- Phone numbers are appended in a fixed order — primary phone first, then message phone — only when each is non-null.
