Fil and I are pushing forward with the expanded scope of ECR E2400330 to upgrade the whitening stages of the OSEM PD satamps for the top masses of the filter cavity HSTS. More details on the actual upgrade once installed, but I figure a separate instructional aLOG is warranted for the prep we did since the SQZ system and these kind of "once in a blue moon" activities for the filter cavity are still relatively new to folks.

(1) Offloaded SQZ WFS DC alignment request to FC1, FC2, and ZM3 to their respective alignment sliders.
    - assume that the overall SQZ_MANAGER is already in DOWN.
    - open the SQZ_FC sub-manager guardian log
    - open ndscope of top mass OSEMs to check that over alignment of the SUS *doesn't* end up changning
        $ ndscope H1:SUS-{FC1,FC2,ZM3}_M1_DAMP_{P,Y}_IN1_DQ
    - request SQZ_FC's goto state FC_ASC_OFFLOADED, watch SQZ_FC guardian log and ndscope trend to confirm expected behavior
    - once done, request SQZ_FC to go back to DOWN.

    We found that this state did exactly as expected -- pushed the static output of the M1 LOCK banks to the (correctly calibrated) alignment slider OPTICALIGN OFFSET, and while there was a minor blip in top mass OSEM record of physical alignment during the transition, the SUS did not move.

(2) Brought FC1 and FC2 to SAFE with their SUS_{FC1,FC2} guardians.

(3) Bypassed the use of OSEM readbacks for the IOP software watchdog (SWWD).
    - from the sitemap, opened the "SWWD" overview screen from the "WD" dropdown in the far bottom left corner
    - opened each HAM7 and HAM8 SWWD screens
    - made sure the bypass time, H1:IOP-SUS_{FC1,FC2}_DK_BYPASS_TIME, was set to some long amount of time (e.g. 12000 [seconds]).
    - hit BYPASS, H1:IOP-SUS_{FC1,FC2}_DACKILL_BPSET
