Genuinely unresolved points this atlas records rather than silently guesses at: a debated etymology, a contested classification boundary between two related languages, a disputed date for a script's own origin, or any other fact where the scholarly record itself disagrees. An open question is attached to the entity it concerns and stays visible on that entity's own page, so a reader sees the atlas's own honesty about what is not settled rather than a single confident answer standing in for real disagreement.
