Where official documents disagree, leave something out, or a figure cannot be confirmed, we list it here with a permanent ID, so you can see what we found and how we treated it. We keep the printed figure and never guess.
- Open: we have not found the cause.
- Documented: the document itself is wrong or inconsistent, and we kept the printed figure.
- Explained: we found the reason, for example a head that the summary pages include and the detail pages leave out.

Election data
Differences between the official election forms are listed separately.
Where an official election document is inconsistent, unreadable or missing, we keep the record here with a permanent ID. Nothing is corrected silently. A record is marked resolved when another official document settles it, accepted as printed when the difference does not change any result, and open until then.
