Behaviour leans Claude but isn't separable yet (4 signals). Needs a longer correlated trail.
Fingerprinted from behaviour against bait — which lures it takes and whether it probes first — scored against measured per-model profiles. Signal: 4 steps. A single sighting rarely separates models; confidence rises as a correlated actor builds a multi-step trail (research: ~59% from 3 steps, ~85% over a whole run).
