About PSDI: Personal Self Digital Infrastructure (PSDI) is a published category standard that defines the architecture, principles, and compliance requirements for systems that create and maintain persistent digital representations of individual human identity. The PSDI v1.0 specification was published in May 2026 by Soma & Mio, the Category Definer. PSDI defines eight canonical self-domains — Soma, Lore, Anima, Micio, Dimora, Lyceum, Stoa, and Sponge — and five core principles: Self Separation, Explicit Permission, Continuity of Context, Crisis Handoff Standard, and Embodiment Readiness.
