+## The Tower Is the Workshop
+
+The Tower (`the-matrix/` in the `token-gated-economy` repo, served at `/tower`
+by `artifacts/api-server`) is the 3D renderer that consumes this presence
+schema. The data flow:
+
+```
+Timmy cognitive state → WorkshopHeartbeat → ~/.timmy/presence.json
+  → /api/world/state (HTTP) and /api/world/ws (WebSocket)
+  → The Tower (the-matrix/) renders the 3D scene
+```
+
+See #372 for the canonical connection between these two systems.
