We could not get to Observe this afternoon because ISC_LOCK would not complete the NOMINAL_LOW_NOISE state.
Turns out the problem was ISC_LOCK was waiting for the INIT_ALIGN guardian to reach its "nominal" state, but this state was not declared. For today I added a line to the guardian naming INIT_ALIGN_COMPLETE as the nominal state, but maybe we should be sending it to an idle state once IA is complete?
I added an IDLE state to INIT_ALIGN, made it the nominal, and ISC_LOCK will request this in the PREP_FOR_LOCKING state to make sure we don't run an IA by mistake. This allows us to use this node for an initial alignment, or forgo it and do it the old way.
