Open Questions

The category anchor for this atlas's recorded open questions: a dating uncertainty, a disputed origin, a contested classification, or another gap the current sourcing cannot close, captured so a reader sees the limit of what is known rather than a false certainty. Does not include an ordinary entity gap such as a missing description or citation, which is tracked through the fill checklists rather than recorded as an open question.
