Most anti-detect tooling still optimizes the wrong objective: it treats fingerprinting as a collection problem, enumerate every readable property, then make each one plausible. But a defender does not grade properties in isolation. It grades whether the values you emit across independent layers could have come from the same real machine. A canvas hash that survives CreepJS tells you nothing if your TLS ClientHello says Chrome 126 and your navigator.userAgent says 138.
