# Permissions linking vocabulary

**🟡 Intermediate · 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](../../intermediate/index.md) 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.
