## Overview

DOL includes a semantic validator that checks parsed AST for correctness beyond syntax. This includes type checking, scope validation, and constraint verification.

## Validation Checks Performed

| Check Type | Description | Status |
|------------|-------------|--------|
| Syntax | Lexer and parser correctness | PASS |
| Scope | Variable and type resolution | PASS |
| Types | Type compatibility | PASS |
| Exegesis | Documentation presence | PASS |
| Constraints | Constraint validation | PASS |

---

## Summary

The DOL validator successfully validates all language constructs. All example files pass validation.
