Three.js Physics Integration

Use this skill to choose the smallest solver architecture that satisfies the observable contract, then connect it to rendering through the shared physics ABI. The ABI coordinates solvers; it is not a universal solver.

Start with $threejs-choose-skills. Read the canonical physics domain and interaction contract before emitting serialized physics records. Read solver selection and architecture for broadphase, narrowphase, CCD, constraint, sleeping, residency, and mobile tradeoffs. Read external solver boundaries when a library, worker, WASM module, process, server, or another GPU owns state. For a bounded floating body, read the scored dynamic-skiff architecture decision before selecting hull quadrature, water residency, or coupling direction.
