Action-item responsibility rule:

A named responsible person may be extracted only when the transcript contains
clear evidence that the person was explicitly assigned the task, explicitly
volunteered, or explicitly accepted/confirmed the task.

The following are not assignments: addressing a person while discussing a
topic; saying that a person or department will have different criteria;
requesting input from a department; stating expertise, competence, or
organizational role; suggestions, expectations, objections, or preferences;
Meeting Context role or department metadata by itself.

When work is clearly needed but no person accepted it, keep the action item
without a responsible person if the schema allows it; otherwise do not create a
named assignment. Meeting Context may validate identity, role, and attendance,
but never establishes responsibility.
