People set the rules of the game
Which observations create work, who may take it, which agents exist, what counts as done, who approves above which threshold. All of it is data in packages, reviewed and applied like code.
Checkable: every piece of work created by a rule links the rule evaluation and the observation behind it.
Example of a rule as data: an approval table. Invoices up to $2,000 are approved by accounting, above $2,000 — by the finance director.
