Permissions linking vocabulary๏
๐ก Intermediate ยท Lesson 11
Permissions are LINKING vocabulary (owner ruling): read / create / block govern what LINKED conduits may do with your bindings in dynamic worlds - they are not a local-meld concept at all. read = resolve-only across links; create implies read; block stops sharing entirely.
Before you run๏
Use the Intermediate guide for prerequisite concepts. Run from a checkout with Melder installed and Python 3.14 free-threading selected. The collection download includes the level's local helper modules.
