Perfect! I have successfully completed the task. The solution:                  


                                    Summary                                     

I've created an ASP-based solution that models alternative history scenarios    
with complex dependencies:                                                      

                           Key Features Implemented:                            

 1 Original Timeline: Uses deterministic pivot selection by choosing the        
   earliest year event (age_of_sail at 1400) when multiple pivots are possible  
 2 Alternate Timeline: Applies interventions (preventing age_of_sail), which    
   forces the selection of age_of_steam instead                                 
 3 Conditional Prerequisites: Correctly implements "requires X unless Y" logic -
   alternate_industrial_revolution needs global_trade_routes UNLESS age_of_steam
   occurs                                                                       
 4 Cascading Effects:                                                           
    • Prevented: age_of_sail, discovery_of_new_world, global_trade_routes       
    • Activated: age_of_steam, industrial_revolution, information_age           
 5 Optimization: Uses #maximize to find the maximal set of events that can occur
   in each timeline                                                             

                             Solution Verification:                             

✓ Original timeline correctly chooses age_of_sail (earliest pivot)              
✓ Alternate timeline correctly prevents age_of_sail and chooses age_of_steam    
✓ Conditional prerequisite logic works in both timelines                        
✓ All prerequisites and constraints are satisfied                               
✓ No paradoxes detected                                                         

The final code is saved and produces the correct JSON output format as          
specified.
