`ITaskService` declares a service contract in the Claims / Tasks area, implemented outside this library (most likely in SAIF.Services, per the declare-here, enforce-elsewhere pattern documented for this library)*.

## Purpose
- Declares the operations that a SAIF.Services implementation must provide for the Claims / Tasks area*.

## Context
- Namespace: `SAIF.Core.Contracts.Claims.Tasks`
- Kind: Interface
- Assembly/package: `SAIF.Core` (NuGet package `SAIF.SAIFCode.Core`)
