Universal game architecture DSL with six primitives (LOOP, TILEGRID, CONTROLBLOCK, POOL, EVENT, DISPATCHER). Use when: (1) designing portable game/sim loops, (2) translating between architectures (68K ↔ Cell ↔ CUDA ↔ ECS), (3) explaining engine structure to AI agents, (4) refactoring chaos into explicit state + flow. Invocation produces: Primitive Map, Dataflow Sketch, Worked Example, Portability Notes.
