    A class for creating a limited error recovery planner.
    
    This planner helps to identify and recover from errors in a process by providing fallback steps.
    It keeps track of executed steps and their statuses, allowing the user to define a recovery path if an error occurs.

    Attributes:
        steps: List of dictionaries representing each step in the process. Each dictionary contains
               'name': str - The name of the step,
               'status': bool - Whether the step has been successfully completed (True) or not (False).
        
        fallbacks: Dictionary that maps an erroneous step to its recovery steps.
                   Keys are step names, values are lists of steps that can be taken if the key step fails.
