samples/PhysicsDemo ties physics, audio, input, and rendering together through nothing but the kernel's own vocabulary — no plugin here references another plugin's implementation, only Contracts. Press Space to drop a box; engine.physics simulates it falling onto a static ground; CubeRenderer (new — engine.render's QuadRenderer drew flat cards, no good for a physics demo where a BoxCollider needs to actually look like a box) draws it; physics-demo-game watches each spawned box's own Y velocity via IPhysicsService and plays a bounce sound via IAudioService the moment a real fall settles. A looping ambient track plays throughout via AudioSource's own PlayOnAwake. project.json deliberately excludes engine.editor — this is the shippable configuration M4's "done when" actually asks for, not the dev one. "Landed" isn't a Box3D contact event — the native shim never exposed one (nothing but scalars crosses that boundary, see lingua_physics.c). Watching velocity every frame is the honest, right-sized alternative for a demo this size, not a shortcut around missing infrastructure. Verified two ways. First, real Space-key input isn't simulable here (no xdotool/ydotool under this Wayland session) — so PhysicsDemoGame.Tests drives the actual PhysicsDemoGamePlugin.Configure/Tick through the real Schedule with a controllable fake IEngineInput (and fake IPhysicsService/ IAudioService, since engine.physics/engine.audio's own correctness is already covered elsewhere): spawn-on-press with edge detection, the Rigidbody/BoxCollider/CubeRenderer combo the spawned box actually gets, and — the case most likely to be subtly wrong — a box that never actually falls doesn't false-positive as "landed," only one that fell past FallingThreshold and then settled does, exactly once. All 5 passed immediately. Second, a real windowed run: a box placed in scene.json above the ground visibly falls and settles onto it on screen after a real few-second wait — screenshotting by --screenshot-after-frames alone turned out not to prove this (VSync is off, so frames race by far faster than real physics time passes; enough elapsed frames isn't enough elapsed seconds), an interactive run with a real sleep before the screenshot command is what actually shows it. Full suite: 92 tests. Remaining for M4: the Linux + Windows build pipeline.
