# Permissions create vs read

**🟡 Intermediate · Lesson 22**

Permissions LIVE - they are the sharing policy on a contract. "create" lets the borrower construct/resolve fully; "read" is resolve-only across the link. This is where the vocabulary from the cheatsheet finally does something.

## 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.

## Run the saved script

```bash
python UX_and_AIX_experiences/02_intermediate/22_permissions_create_vs_read.py
```

```powershell
py -3.14t UX_and_AIX_experiences/02_intermediate/22_permissions_create_vs_read.py
```
