What is the difference between a single anomaly and a bot verdict in bot detection?

A single anomaly is an observation that something looks off, while a bot verdict is a conclusion based on corroborating evidence. For example, an audio channel mismatch can come from a virtual machine, but it can also come from an unusual real device. BotRefund collects the anomaly and cross-checks it against browser, network, device, and behavior data. Only when the complete pattern supports it does the visit get treated as a bot.
