`should_override_type_typed` used `unwrap_nullable()`, which only strips the `?Foo` (Nullable) form and not the `Foo|null` (Union-with-null) form. A nullable-union native such as `object|null` therefore reached the union branch with its `null` member attached; since `object` and `null` are both scalar names, the branch judged the type unrefinable and discarded a generic docblock return like `@psalm-return ?T`, leaving the bare native. Use `non_null_type()` (strips null from both Nullable and Union forms) so the non-null part is analysed, matching the function's documented `Foo|null → Foo` intent. Fixes inherited generic returns such as Doctrine's `ServiceEntityRepository<T>::find(): ?T` resolving to `object|null`. Adds an assert_type regression fixture.

@AJenbo I think CI won't pass unless you run the CI because my fork has no access to project secrets. Or, can I do something about the CI myself? |
