I was getting suspicious that the adjustment of the rotation stage at the end of each step in power might be leading to lock losses, so I commented out rsp.rs_bootstrap_power('PSL', power) in the LASER_PWR guardian and reloaded it. The next attempt at locking succeeded, although we are only at 36.6 W. I hope this doesn't mess with the calibration?
I reverted the SDF differences in the attached screenshot. I suspect they are from the INCREASE_FLASHES state?

I'd agree the SDF diffs are from INCREASE_FLASHES. The state just saves the TEST offset values and then puts them back in when it's done, so I'm surprised that the values it put back in seem rounded from the originals. I'll look into it.
What was happening that made you think that the bootstrapping was the issue?
