Every decision tick sends one request carrying a Choice per cell. Between ticks the code keeps steering toward the chosen intent, so motion stays smooth while Jev answers.

Cells · change a persona mid-round

Options are built from the situation: graze a pellet-rich direction, hunt an edible cell, or flee one that can eat you. Jev only ever sees options that exist right now.

How it works

Agar rules, simplified: eat pellets to grow, eat any cell you outweigh by 25% or more, bigger cells move slower, mass above 50 slowly decays, eaten cells respawn small after three seconds. Cells start at random sizes so the food chain exists from the first second. Biggest mass when the clock runs out wins. Each tick the code lists what each cell could do right now (the two richest pellet directions, up to two edible targets, up to two threats) with distances, mass ratios and whether the gap is closing. Jev returns a probability per option; the cell commits to the argmax until the next tick.
