## How we test this category

A sandbox queue of ten tickets in every helpdesk. An agent retrieves context, drafts a reply, adds an internal note and changes status. We score permissions, safe handoff, audit trail and API coverage, and never send the test replies to real customers. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.
