"""Change C2 (Gitea issue 24): a Q.C. reject always needs a detailed reason, and a packet rejected without an NCR
number cannot be accepted until the NCR number is given with the accept (QC_ACCEPT and QC_ACCEPT_AND_ROUTE).

The packet read says `ncr_required`; can() does not block on it (the NCR comes with the step); the server refuses
the step without it, 422 ncr_required. The accept stores the NCR on its inspection and in the log."""
