Redmine's role setting for issue visibility offers three choices, and the
narrowest means author or current assignee — nothing else. So the moment you
hand a ticket to a colleague it disappears from your view, including the
comments you wrote on it. This adds a fourth choice where involvement counts:
Issues the user is or has been involved in. Handovers, reviews and "I fixed
this last month" stop breaking.
