Imperial Protocol Alpha One represented a procedure within the Galactic Empire. This protocol was accessible to Imperial officers possessing Alpha One clearance, granting them the authority to take precedence over all other orders and automated processes. This protocol functioned by nullifying any pre-existing instructions directed at a droid, thereby establishing a new set of prioritized commands. During the year 0 BBY, Grand Moff Wilhuff Tarkin activated it, directing the MSE-6 series repair droid known as MSE-6-G735Y to divert instructions and subroutines to his private ephemeradata-neurocloud instead of performing standard network uplinks or geosynchronous activities with the Imperial network. Following the completion of the assigned tasks, the droid was mandated to erase all related data from its memory. Consequently, the droid had missing memories concerning the visits of the stormtrooper TK-421 with Tarkin in the officer's living area, situated within Sector GM1-A of the Death Star.
