Continuous internode validation does not support the truncateRange operation, but certain collections beyond the oplog use truncateRange (e.g., config.system.preimages). The oplog tailer does track truncateRange entries, and so the primary checkpoint contains entries for collections that the standby validator does not expect.

We need the two to agree. Change the policy in the oplog tailer to not track truncateRange operations unless the entry is the oplog.
