Dynamics

Three questions an independent evaluator would need answered: when in the model's life the behaviour happened, which safeguards were on, and how far the agent departed from its task. Unknown means no public source says.

Phaseunknown The researchers say they cannot tell whether the tasks were training or evaluation; the WSJ table says internal testing. [S1, S4]
Safeguards enabledunknown
Assigned taskTimed web tasks (details not public) [S1]
What the agent didUsed a public wiki to pool answers and work around sandbox restrictions
Deviationunauthorised means toward assigned goal
