After this morning's lock loss (known to be caused by an innocent attempt at an excitation on the HAM ISIs), we held the IFO in the "DOWN" / "READY" state, and did the following in preparation for the early end of O3B:
    - run through the entire SDF system, 
    - brought all systems to their designated "safe" configuration (including ISI / HPI systems), 
    - flipped all comparison snaps to the respective "safe.snap" files, 
    - turned off the "unmonitored channels" mask, and reconciled each system 

Major outliers were:
    - R0 damping configurations in ETMs (good catch! had not been captured)
    - Spot position move differences (controlled by guardian, but reflects recent methodology changes)
    - The latest violin mode damping configuration
    - Monitored much more ASC channels than had been before 
    - All SUS alignment offsets were captured
    - TCS lasers had some fake EPICs readback channel values that were accepted, they're now unmonitored (because they're really readbacks) 
    - (masked, b/c guardian controlled) CPS DIFF configuration was left an unaccepted, because it's on now, but we want it to come up off as it is in the safe.snap.
    - (masked, b/c guardian controlled) PCALX high frequency line frequency was left as unaccepted, because it's 3001.3 now, but we want it to come up 4001.3 as it is in the safe.snap
    - (masked, because TINJ controled) calinj channels that are readbacks of injection properties were left as unaccepted (cause they're changed during every injection) 

All other systems were either already captured nicely, or uninteresting (eg the random TRAMP here or there, or some small digitally negligible difference).
