# Policy

a rule that chooses among the ready arms of a strategy, a play, an actor or a content, and logs the odds of its choice; a tenant may choose another row and replay it on the history first

[figure: Policy is a row at platform scope. The drawing shows its fields and the objects that they point at.]
