Should it be module.parent.parent?

Currently, parent-require calls require in module.parent, which is the calling module.

However since it's "parent-require" I think it should be looking in the module's parent, which is module.parent.parent

Inspect the parent-require implementation and its existing test coverage to verify which module is used as the require context. Confirm whether resolving from the caller's parent matches the package's intended behavior, then update the behavior and tests so the expected parent-level module resolution is covered.
