    In some cases, the Jujutsu backend was miscomputing the necessary base
    
commit, creating parent diffs where none were required. This was an
    
error in my code where I was passing the tip commit ID to
    
_get_fork_point instead of base.
    
 
    

    





  

    
 
 
    
  
    Posted an old commit that previously triggered this behavior and
    
verified that it no longer created a parent diff.

    In some cases, the Jujutsu backend was miscomputing the necessary base
commit, creating parent diffs where none were required. This was an
error in my code where I was passing the tip commit ID to
`_get_fork_point` instead of base.

Testing Done:
Posted an old commit that previously triggered this behavior and
verified that it no longer created a parent diff.
