Why Pick Biologist?
Biologist makes RACCOIN easier to understand by reducing the punishment for imperfect timing. The Cat plus Rat shell creates tempo and sustain, which means you spend more time making meaningful decisions and less time dying to resource pressure.
Core Plan
Use Cat plus Rat to keep charges flowing, stabilize the run with one good chip, then add generic scaling or a second engine once the board already feels safe.
