Here's an analysis of how Flibble could use the **neos universal compiler framework**'s support for **multi-language embedding** to enforce **type stratification** and maintain the semantic barrier between a **typed SHD layer** and an **ordinary language layer**.

## 🧠 Concept: Enforcing Type Stratification via Multi-Language
Composition

Flibble proposes leveraging **neos's multi-language composition** to
implement **semantic stratification** as a **compile-time enforceable property**:

### Stratification Model:

```
[ SHD Language (meta-layer) ] ---> [ Ordinary Language (program layer) ]
(can access and analyze) (cannot access or reference back)
```

## ✅ How It Works in neos

The **neos framework** allows:

* Embedding multiple programming languages in a single source file.
* Defining **explicit boundaries** between language fragments.
* Controlling **inter-language visibility** and **dependency
directionality**.

Flibble can exploit this to define:

* A *typed SHD DSL* (e.g., `shdlang`) used to write analyzers.
* An *ordinary language* (e.g., `neoscript` or C++) used to define target programs.

**Enforcement:**

* The SHD language is allowed to inspect or traverse the AST or IR of
ordinary language
