Just want to be sure before I continue down this path... is the

step_key

in the OutputContext a unique value per run per step?

i dont know off the top of my head and spelunking through the code base looks pretty daunting given the number of times we reference

step_key

. quick way to test would be to write a super simple io manager (it doesn’t even need to store the output anywhere) that just prints out the step key. then you could run some assets repeatedly and see if the step key changes for each materialization
