what is Declared vs stealth agent roster?
How notable agent classes declare themselves (UA string, published fetch IP ranges, Web Bot Auth, or nothing). Search crawlers publish verifiable IP ranges; on-behalf-of-a-user browser agents (Operator/Atlas) declare a UA but behave as the operator-synthesis case; orchestrated-browser and raw-CDP stealth automation declare nothing and fall to probabilistic + latency signals.. Fast-decaying declared-agent roster + timeline; several rows speculative. asOf 2026-06-15.
