+/// <remarks>
+/// The files in the folder Fixtures were written by the anonymous shapes themselves, before the records existed. The
+/// content data and the protected data for the validation reach the HTML of a briefing, and the fingerprint of the
+/// editor decides whether a briefing gets saved: a field under another name or in another place changes all three.
