Stage 2: render pipeline and UI toolkit over gpu/platform. Stage 3: schema registry, asset pipeline + runtime loader, scene graph and ECS. Stage 4: editor — docking, inspector, scene/game views, play mode, asset browser, console, profiler; 4.5 adds the 3D foundation (mixed 2D/3D spaces, meshes, depth). Stage 5: Aego Script — compiler (lexer/parser/types/resolver/checker/asm/compiler), bytecode with verifier and register VM, instance runtime, stdlib, native bindings, and editor/CLI integration (aego run/edit/check/test/dump).
