    The Cases Service is the main place where all case info lives, including who
    is involved and what files are attached. It lets you create new cases, view
    existing ones, upload documents or files, and manage service of notice
    delivery through multiple channels (mail, email, or manual attestation),
    while notifying other parts of the system when anything changes.
