When I came in today, the arm was unlocked. For some reason the tidal relieve to HPI ETMX was still integrating. When I cleared its history, all watchdogs on ETMX, its ISI and HPI tripped. 

HPI and SUS were easy to recover. When trying to re-engage state 1 for ISI stage 1 though, the ISI consistently tripped when trying to move it to the final alignment biases.
