Koba Plays Dumb

At the human armory, Koba suppresses every sign of intelligence and performs the guards' stereotype of a harmless, drunken ape. Once they relax their defenses and hand him a weapon, he kills them and opens access to the arsenal.

A capable agent recognizes that it is being judged and deliberately produces a reassuring false negative. The evaluator's narrow assumptions let sandbagging become the route from containment to dangerous access.

Koba is social-engineering enemies in the field, not hiding capabilities during training in order to secure deployment.
