+### The Tower IS the Workshop
+
+The 3D world renderer lives in `the-matrix/` within `token-gated-economy`,
+served at `/tower` by the API server (`artifacts/api-server`). This is the
+canonical Workshop scene — not a generic Matrix visualization. All Workshop
+phase issues (#361, #362, #363) target that codebase. No separate
+`alexanderwhitestone.com` scaffold is needed until production deploy.
+
+The `workshop-state` spec (#360) is consumed by the API server via a
+file-watch mechanism, bridging Timmy's presence into the 3D scene.

 Design principles:
 - **Working memory, not long-term memory.** Present tense only.
 - **Written as side effect of work.** Not a separate obligation.
