+### Tests Double as Samples
+
+The project is designed so that **test cases serve two purposes**:
+
+- ✅ **Unit Tests** – validate the framework’s correctness.  
+- 📖 **Usage Samples** – demonstrate how to use these libraries through test cases.  
+
+This approach keeps the codebase compact and avoids redundant “hello world” style examples.  
+Instead, the same code that proves correctness also teaches usage.  
+
+This mirrors the **Meson build system** itself, which tests its own functionality by using Meson to test Meson.  
+In the same way, Fossil Logic validates itself by demonstrating real-world usage in its own tests via Fossil Test.  
+
+```bash
+meson test -C builddir -v
+```
+
+Running the test suite gives you both verification and practical examples you can learn from.
