Overage & Burst Policies — Defines what happens when usage exceeds the entitlement — hard stop, throttle, bill at an overage rate, or allow a temporary burst. Enforcement and metering apply the policy in real time, and the rating engine prices whatever it permits.
Overage & Burst Policies lives in the Consume & Meter phase of Fulfill & Bill — the stage where you activate what was sold, meter what's used, bill it right. In the corpus tool index this phase maps to the Meteringcategory.
