source module dbx_patch.patches.python_path_hook_patch

PythonPathHook Patch for Editable Installs.

This module monkey-patches dbruntime.pythonPathHook.PythonPathHook to preserve editable install paths when sys.path is modified by the Databricks runtime.

The PythonPathHook manages sys.path updates when changing notebooks or working directories. Without this patch, editable install paths can be lost during these updates.
