These squeezer SDFs were fixed and reverted.  The squeezer guardian (SQZ_MANAGER) was stuck, and so we weren't injecting squeezing.  Even with the SDFs accidentally accepted, the guardian properly prevented us from going to Observing, since the SQZ_MANAGER was not in its nominal state.  It turns out that even though JeffB had toggled the squeezer's noise eater on, then off, that wasn't enough to convince the squeezer to lock all the way to injecting squeezing (we tried turning it back off only a few seconds, so that we didn't forget later). 

So, I have added to the SQZ_MANAGER guardian to turn ON the squeezer noise eater in the DOWN state, and to turn back OFF the noise eater in the SQZ_ASC state (just before it's nominal state). 

I have not yet loaded the SQZ_MANAGER guardian - this should be done next time we are out of Observing for a moment, so that operators no longer should have to deal with this.  I am leaving a sticky note with JeffB and his backup Cheryl as a reminder.

I moved the sqz noise eater ON to the Locking_TTFSS state, since it seems like we jump from Squeezing straight to Locking_TTFSS, and don't go through DOWN, so it hasn't been getting turned on.
