Hylos: Operability Contracts for Model-Native Spatial Intelligence

ArXi:2605.24728v1 Announce Type: new Foundation models can increasingly describe, reconstruct, and generate 3D objects, assemblies, scenes, and environments, but visually plausible spatial output is not yet operable 3D. A generated object or environment becomes useful to an agent only when the system can identify its entities, frames, surfaces, constraints, provenance, admissible actions, expected effects, and validation failures. The paper is framed as a systems/position preprint with a focused artifact study rather than a broad benchmark.
