+### Getting Arrays Instead of Entities
+
+By default, queries and result sets return [Entities](../orm/entities) objects.
+When you only need plain arrays, use `findUnhydrated()` instead of `find()`:
 
 ```php
-$query->disableHydration();
+$query = $articles->findUnhydrated();
 
-// $data is ResultSet that contains array data.
+// $data is a ResultSet that contains array data.
 $data = $query->all();
+
+// Terminal methods are typed as arrays too.
+$row = $articles->findUnhydrated()->where(['id' => 1])->first(); // array<string, mixed>|null
+```
+
+`findUnhydrated()` accepts the same finder type and arguments as `find()`, so
+your existing [custom finders](#custom-find-methods) are reused unchanged:
+
+```php
+$rows = $articles->findUnhydrated('published')->all();
 ```
 
+It returns a `Cake\ORM\Query\SelectUnhydratedQuery`. This behaves exactly like
+`find()->disableHydration()` at runtime, but its static type matches the array
+result shape, so static analyzers no longer see `entity|array` on `first()`,
+`firstOrFail()`, `all()`, `toArray()` and iteration — including after the query
+flows through a custom finder.
+
+> [!NOTE]
+> `findUnhydrated()` only changes the result shape for row-returning finders.
+> `findList()` and `findThreaded()` produce a key/value map or nested tree
+> regardless of hydration, so there is nothing to type differently for them.
+
+> [!WARNING]
+> `SelectQuery::disableHydration()` is deprecated as of 5.4.0 and will be
+> removed in 6.0. The fluent toggle returns a query whose static type still
+> claims to produce entities; prefer `findUnhydrated()` instead.
