While investigating my own mess, I discovered that some scap logs had the wrong date:
ls -ltr scap/log .... -rw-rw-r-- 1 awight wikidev 10096 Nov 8 16:49 scap-sync-2017-11-08-0001.log -rw-rw-r-- 1 awight wikidev 83060 Nov 20 22:27 scap-sync-2017-11-08-0002-1-g5084251.log -rw-rw-r-- 1 awight wikidev 25178 Nov 20 22:55 scap-sync-2017-11-20-0001.log -rw-rw-r-- 1 awight wikidev 7161 Nov 20 23:19 95cd523.log -rw-rw-r-- 1 awight wikidev 32871 Nov 20 23:38 scap-sync-2017-11-08-0003.log
I remember that I had run scap deploy-log on those 11-08 files, and that they existed before I ran my 11-20 deployments. It seems that scap deploy picked up the last filename given to deploy-log, and overwrote it.
