[bug\_fix] ImportError: cannot import name 'X' from partially initialized module 'A' \(most likely due to a circular import\)

Break the cycle by moving the import into the function or method that uses it \(lazy/local import\) so it executes after both modules finish initializing, or extract shared definitions into a third module that both A and B import.

Journey Context:
You refactor code so module A imports module B, but B already imports A at the top. On startup, Python begins loading A, then loads B while A is only partially initialized, then B tries to import A again and fails because A's namespace is not complete. Moving the import inside the function that needs it defers resolution until both modules are fully loaded, eliminating the partial-initialization error.
