What is a potential consequence of a document being assigned to a logged-off user in an Active Learning project?

In an Active Learning project, when a document is assigned to a logged-off user, it presents a significant challenge regarding visibility. Specifically, the document becomes inaccessible to any reviewers because there is no active user to engage with it. This lack of access likely leads to delays in reviewing, coding, or making any determinations about the document's relevance or content until it is reassigned to an active user. As a result, the project could face bottlenecks in workflow and productivity, underscoring the importance of effective user management in collaborative environments.

The other outcomes do not accurately represent the implications in this scenario. For instance, coding cannot proceed if the document is invisible to reviewers, nor is it truly "lost" if it remains in the system but just needs a different user to take over the task. Furthermore, the document coding cannot be completed by just any user if it is assigned to a user who is logged off, as those specific assignments control who has access to that document at any given time.
