The documented open questions this atlas records against its own subjects: unresolved debates, gaps in the sourced record, or contested calls a reader should see named honestly rather than silently smoothed over, such as the ongoing debate between structure and agency in social theory, or the unsettled ethics of colonial-era ethnographic fieldwork. Belongs here: a specific unresolved question tied to a subject this atlas documents. Does not belong here: a settled fact still awaiting a citation, which is an ordinary sourcing gap on the entity itself, not an open question in this sense.
