…eria Research Newton 1.0 (GTC 2026) and document the roboharness integration strategy in docs/spike-newton-backend.md: - Summarises Newton's capabilities, hardware requirements, and current adoption state (April 2026: ~2k stars, Isaac Lab + RoboVerse MetaSim support, API documentation still forming) - Maps all 7 SimulatorBackend protocol methods to Newton equivalents (step, get_state, save/restore_state, capture_camera, get_sim_time, reset) - Documents two integration paths: Option A via RoboVerse MetaSim (zero Newton-specific code needed), Option B via a direct NewtonBackend - Notes that Isaac Lab users already get Newton coverage today via RobotHarnessWrapper (Isaac Lab's Newton backend exposes gymnasium.Env) - Defines concrete adoption criteria (≥5k stars, stable API, etc.) for Q3/Q4 2026 re-evaluation - Updates ARCHITECTURE.md to list Newton and RoboVerse as planned backends - Updates roadmap §E to reference the spike doc https://claude.ai/code/session_011MH7R34wN8JSDYDGVQu2b9
