+### 📦 Export Integrity Tests
+
+This folder contains tests that validate the structure and accessibility of public exports — such as those defined in
+`lib.ts` or `components/index.ts`. These tests ensure that all components, utilities, and modules are properly exposed
+and can be imported without error.
+
+> ⚠️ **Important note on coverage:**  
+> Code coverage tools may report artificially high coverage when running export tests. This happens because files are
+> marked as "covered" simply by being imported — even if none of their internal logic is executed. As a result, components
+> may appear to have 100% coverage despite not being functionally tested.
+
+### ✅ For accurate coverage reporting
+
+To ensure meaningful coverage metrics, run your **unit and integration tests separately** and **exclude export-only
+tests** from coverage analysis. You can do this by updating your `vitest.config.ts` like so:
+
+```ts
+coverage: {
+  exclude: ['tests/exports/**']
+}
+```
+
+This keeps your coverage report focused on actual logic execution, not just import validation.
