utils/wizard_navigation library

Classes

WizardNav

Navigation-aware prompt wrappers used by the interactive wizard.

Exceptions / Errors

BackNavigation

Sentinel exception used by every wizard prompt to signal that the user asked to step backward to the previous question. Wizards catch it and re-run the previous step instead of advancing.

CancelNavigation

User-cancelled navigation (Ctrl-C, typed quit, etc). Distinct from BackNavigation because the wizard should abort the entire flow rather than rewind one step.
