+
+**What it does**
+
+Checks for classes that inherit from a dataclass with `order=True`.
+
+**Why is this bad?**
+
+When a dataclass has `order=True`, comparison methods (`__lt__`, `__le__`, `__gt__`, `__ge__`)
+are generated that compare instances as tuples of their fields. These methods raise a
+`TypeError` at runtime when comparing instances of different classes in the inheritance
+hierarchy, even if one is a subclass of the other.
+
+This violates the [Liskov Substitution Principle] because child class instances cannot be
+used in all contexts where parent class instances are expected.
+
+**Example**
+
+
+```python
+from dataclasses import dataclass
+
+@dataclass(order=True)
+class Parent:
+    value: int
+
+class Child(Parent):  # Ty emits a warning here
+    pass
+
+# At runtime, this raises TypeError:
+# Child(1) < Parent(2)
+```
+
+Consider using [`functools.total_ordering`] instead, which does not have this limitation.
+
+[Liskov Substitution Principle]: https://en.wikipedia.org/wiki/Liskov_substitution_principle
+[`functools.total_ordering`]: https://docs.python.org/3/library/functools.html#functools.total_ordering

-### Calling `super()` in overridden methods with `Self` return type
-
-This is a regression test for <https://github.com/astral-sh/ty/issues/2122>.
-
-When a child class overrides a parent method with a `Self` return type and calls `super().method()`,
-the return type should be the child's `Self` type variable, not the concrete child class type.
-
-```py
-from typing import Self
-
-class Parent:
-    def copy(self) -> Self:
-        return self
-
-class Child(Parent):
-    def copy(self) -> Self:
-        result = super().copy()
-        reveal_type(result)  # revealed: Self@copy
-        return result
-
-# When called on concrete types, Self is substituted correctly.
-reveal_type(Child().copy())  # revealed: Child
-```
-
-The same applies to classmethods with `Self` return types:
-
-```py
-from typing import Self
-
-class Parent:
-    @classmethod
-    def create(cls) -> Self:
-        return cls()
-
-class Child(Parent):
-    @classmethod
-    def create(cls) -> Self:
-        result = super().create()
-        reveal_type(result)  # revealed: Self@create
-        return result
-
-# When called on concrete types, Self is substituted correctly.
-reveal_type(Child.create())  # revealed: Child
-```
