Internal — not documented

The IK/solver math (IKSolver and internal solver types behind AR51Character/Person.SolveIK), the platform fallback adapters (EmptyHandsAdapter, EmptyControllerAdapter, DefaultBoundaryAdapter), device-capture plumbing, PersonIdLabelFactory, and the gRPC/proto wire types are intentionally excluded — they're internal or proprietary.
