A change to one deployment - its replica count, its per-pod CPU and memory requests, parking it, or promoting a build into it - is read from its object cost projection and moved by the metering's own allocation rule; a new environment or a database preset is priced on the cluster it would run on as the share that cluster's latest metering pass would have allocated it, compute only, so a floor. The answer carries the confidence of the snapshot it is read from and how it was reached. A change Ankra cannot price (a namespace another application shares, a cluster with no recent snapshot or none recording its capacity yet, a parked deployment's size, a workload the cluster has no room for) answers priced false with the reason, never zero.
