 * Terrence worked on L2P decoupling for the TM.
 * Terrence and Mark edited the Type B Guardian to put turning on the payload damping later in the sequence, to help ensure that the OSEMs are not touching by the time they're needed (which can happen if the BF is buoyancy compensated for vacuum but the suspension is vented).
 * Mark started on a big tidy-up of the cleanbooth.
