+#+TITLE: Naming Convention — Logos, Stoa, Agora, and Identity
+#+FILETAGS: :notes:architecture:naming:
+
+* Project Architecture
+
+| Name | Greek | Layer | Role |
+|------|-------|-------|------|
+| Logos | Λόγος | Mind | The memex, org files — recorded discourse itself |
+| Passepartout | — | Agent | The neurosymbolic agent that traverses all three layers |
+| Stoa | Στοά | Body | Environment — editor, browser, shell, infrastructure (post-v1.0.0) |
+| Agora | Ἀγορά | Society | Decentralized identity, communication, contracts, PDS |
+
+cl-tty is the first harvested library of the Stoa cannibalization pipeline — a pure-CL terminal I/O library, independent of any project.
+
+* Identity Architecture
+
+| Name | Greek | Layer | Role |
+|------|-------|-------|------|
+| Psyche | Ψυχή | Root | Master Key — offline seed, never exposed to network |
+| Persona | — | Identity | Active DID — signs, owns, contracts on the network |
+| Profile / Eidolon | εἴδωλον | Face | Public-facing shadow-image projected by the Persona |
+
+Hierarchy: Psyche → Persona → Profile (emanation, not composition).
