How the tasks rate
What stops the agent
Share of task weight flagged by each barrier; a task can carry several.

Level: consensus of the two models (the lower level when they disagree). Share: part of the task’s working time an agent could take over. Human time: minutes a competent person needs for one instance, as estimated by the models.
