Mutation

Technical definition

In ARTF, a single proposed change to an OpenRTB bid request, defined by an intent, an operation (add, replace or remove) and a path. The host accepts or rejects each mutation independently.

An agent's suggested edit to a bid request. Add this audience segment. Attach this deal ID. Flag this impression as suspicious. The agent proposes. The host decides. Nobody gets to rewrite the whole request unilaterally, and that is the point. Every change is small, labeled, and reviewable.
