What type of navigation does the PerformScreenFlow harness rule use?

The PerformScreenFlow harness rule utilizes breadcrumb navigation without future steps to help users understand their current position within a series of steps in a process. Breadcrumb navigation effectively provides context by displaying the path the user has taken, allowing them to easily navigate back to previous steps if needed.

This method is especially valuable in scenarios where the user is engaging with a complex flow that involves multiple sequential tasks. By presenting already completed steps while not showing future steps, the design keeps the user focused on the task at hand without overwhelming them with options. This ensures that users remain oriented and aware of their progress, enhancing usability and preventing confusion as they move through the process.

In contrast, label-based navigation or tabbed navigation would present a different structure or layout that may not offer the same clarity regarding completed steps and progression. Dropdown navigation could provide access to different sections but lacks the context that breadcrumb navigation provides, which is critical in a guided process flow.
