+## 10) Install Script Requirement
+- Provide `scripts/install.sh`
+- It should register the OpenClaw plugin name as **`yonexus`**
+- Build artifacts must be placed into **`dist/yonexus`**
+
+## 11) Notes & Decisions
 - Structure data is not stored in memory_store.
 - Shared memory uses memory_store (compatible with memory-lancedb-pro).
 - Queryable fields are whitelisted via schema.
