It’s a Satrap!

satrapy (n.): A foreign polity, for whatever reason, temporarily operating with the advice and under the supervision of an Imperial satrap (typically, an officer of the Ministry of State and Outlands of prefectural or higher rank) but not under military occupation; a relationship one step closer than a client-state.

The purpose and degree of management of a satrapy covers many points on a large scale. The most common type of satrapy is a polity in the process of admission (but not yet admitted) as a constituent nation of the Empire, receiving guidance in the process of discovery, challenge, and adaptation. Other satrapies have existed, temporarily, for purposes as widely different as disaster relief, trade protection, and galactic security, with the role of the satrap varying between “friendly and optional advice” and “the consequences can make low orbit within the hour”.
