We tried transitioning to the new DARM configuration today slowly to debug the transition from NEW_DARM -> [nominal] DARM. We've had plenty of success transitioning into the new DARM state recently using the ETMY_NLN and NEW_DARM ISC_LOCK guardian states. However, today we encountered several errors when doing so. Some syntax errors cropped up from a few lines in ETMY_NLN (that neither of us recognized) that kept us from moving beyond the main() method. We ran the run() instructions by hand (with the GRD state back in NLN) and fixed the syntax errors in ETMY_NLN and then continued by hand to the NEW_DARM configuration (while the guardian state stayed in NLN) but lost lock when swapping the gains on SUS-ETM{Y,X}_L3_LOCK_L. We confirmed that all the expected DARM loop filters were installed and engaged as expected before moving to ETMX (NEW_DARM) from ETMY. It's not clear to us yet why we lost lock this time around after having virtually no issues switching to the new DARM state recently.
