>
> While processing edits, the NN may decide after adjusting block totals to
> leave safe mode - in the middle of the edit. Going active starts the secret
> manager which generates a new secret key, which in turn generates an edit,
> which NPEs because the edit log is not open.
> # Transitions should _not_ occur in the middle of an edit.
> # The edit log appears to claim it's open for write when the stream isn't
> even open
