Each row on the left is a group of categorical fields that had options renamed or removed in 2026 and ended up with the same option list. For every wording that no longer exists, pick the current option it means, or mark it as removed. Answers saved with these wordings are hidden today. If an old option list can't be mapped onto the new one, split the history: the states before the split become a separate, deactivated copy of the field that keeps its own options and answers. Answer counts come from every answer in the database copy the data was built from. Field titles and students are left out on purpose.
