Elira lifted two fingers. The screen jumped forward by a second. The trap snapped shut, and the team scattered in panic.
No one was hurt, but their rhythm fell apart. The clip ended quickly, leaving a small silence.
The class shifted in their seats. A few students winced, remembering the sting of their own mistakes from the day before.

They moved slowly, careful not to rush. No one lunged first. They let the creature tire itself out chasing bad openings.
Their formation held, patient and precise. When they finally struck, it was clean and quiet. There was no shouting, no wasted effort. The creature fell in a single, steady motion.
Elira nodded toward the image. "Coordination," she said. "You made a plan small enough to survive living through it. That is the right kind of plan."
