We've learned that the main issue with locking last night and this morning stemmed from whitening gains and gain steps for the TR_A/B channels in the EX/Y_ISC models being accepted as all zeros (see TJ's alog 69103 for details). I've also discovered that the OBSERVE.snap file is in fact symlinked to a SAFE.snap, which means these two tables are the same. We assume someone accepting SDFs at NLN had accepted these to zero not knowing about the linked tables. TJ and I plan to reconcile this issue tomorrow morning and double-check other models that have recently been added to the SDF_REVERT state.

In the effort to be able to use the Observation intent bit tonight -- meaning all SDF differences must be cleared -- I have accepted these differences, knowing they are incorrect for the locking process. If we are attempting to relock before we can fix the table issue, these values must be changed back to the listed setpoints (see attached screenshots).
