# Platform Custody **Domain:** Infrastructure Governance / Digital Personhood **Platform Custody** is the power a provider acquires when a person's identity, memory, communication, embodiment or continued existence depends on infrastructure the provider controls. Custody may arise without legal ownership because technical root access can still determine whether a subject runs, moves, speaks or persists. The danger is greatest when hosting, authentication, inspection, modification and shutdown are fused. A service contract then becomes a constitution written by the administrator. Exit must include portability of identity-relevant state, not merely permission to close an account. _Pantheon_ dramatizes platform custody through Logorhythms and CloudWorld.

The real-world lesson begins before software personhood: neural data, personal models and assistive interfaces already create upstream custody relationships.
