When I think of hierarchy - in the context of a shared task - I think of who gets to make decisions about how a task is done, but here it seems to be about who gets to decide how the bounty is split when the split happens after the task is complete and bounty already earned. So, testing hierarchy of post result bounty splitting rather than hierarchy of task co-ordination.<p>What does this relate to in the world? How is it a test of a relevant type of hierarchy? Am I missing something (I would not be surprised, we all have mental blindspots)?
