Every run gets a spend ceiling and a standard to meet before it starts. Nothing goes out without both in place.
Work that misses your rules gets caught inside Mustang, then stopped, rerouted or sent back before a person or a system sees it.
Spend reads by tier and by function, so you can see what the work cost and shift it without touching anything above.
Replay any run and see the inputs it used, the rules it was held to, and where it spent.
