Thanks for a thorough summary Corey.
While trying to relock today, we had much worse recycling gain after doing initial alignment than what we had on Monday. Hang found that at around 18:06 UTC (11 am local time) the stored values for the ITMY camera were changed. He restored them and Geogria accepted them in SDF, but we don't see any logs about model restarts. It sounds like there was an unintentional restart of that model (43932)
SDF is really not in good shape right now, and it will be challenging for commissioners to keep up with it while we are in this state. It would be great if operators/ other people can help us catch these things by being on the lookout for model restarts and being on top of either checking checking conlog when there are unintentional restarts or checking SDF before planned restarts.
