# IClaimDomainBuilder

Defines the contract for constructing `SAIF.Domain.Model.Claims` domain objects (`Claim` and `Worker`) from various identifiers or lightweight data records, abstracting the wiring of a claim's or worker's collaborators (unit of work, query providers, claim API services) behind a single factory-style interface consumed by services such as `ClaimNotesService` and `TaskService`.

## Purpose
- Provides multiple ways to obtain a fully-constructed `Claim` domain object: by numeric ID, by claim number, or from an already-loaded `InjuryClaim` data record.
- Provides ways to obtain a fully-constructed `Worker` domain object: by numeric ID or from an already-loaded `ClaimPerson` record.
- Centralizes the domain-object construction dependencies so calling services do not need to assemble `Claim`/`Worker` constructor arguments themselves.

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

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| GetClaim(long) | `Claim GetClaim(long claimId)` | Builds a `Claim` domain object for the given claim's database ID. |
| GetClaim(string) | `Claim GetClaim(string claimNumber)` | Builds a `Claim` domain object for the given human-readable claim number. |
| GetClaim(InjuryClaim) | `Claim GetClaim(InjuryClaim claim)` | Builds a `Claim` domain object directly from an already-retrieved `InjuryClaim` data record, avoiding a redundant claim lookup. |
| GetWorker(long) | `Worker GetWorker(long workerId)` | Builds a `Worker` domain object for the given worker's database ID. |
| GetWorker(ClaimPerson) | `Worker GetWorker(ClaimPerson worker)` | Builds a `Worker` domain object directly from an already-retrieved `ClaimPerson` data record. |

## Behavioral notes
- Implemented by `ClaimDomainBuilder` in this same namespace, which supplies the unit of work, user profile service, query providers, and claim API services each domain object needs.
