      WT-17905 introduced a new guard to ensure that no user data containing a "tombstone encoding" gets persisted to disk.

      WiredTiger is supposed to prevent such a state by applying proper escaping to potential conflicting values; nevertheless, regressions (e.g.) started appearing while the Server CAR team was testing changes to the chunk migration infrastructure (which now includes the persistence of a recovery document to record its progress).

      It is believed that the exact content of the document (and the way this gets updated) may be instrumental to reproduce the scenario.
