Legacy Physics Adapter Migration Audit

This page is retained only so that old document links continue to resolve. It does not define a runtime interface, experiment protocol, or acceptance claim.

The current design is in Physics Studio Architecture. The current verification state and required evidence are in Physics Studio Author-Fidelity Verification.

Historical native reproduction commands live under scripts/physics/official_repro/. They are deliberately separate from Studio benchmark runs and their outputs never enter a common comparison.

The retired mimic loaders, native rollout converters, runtime manifests, versioned schemas, generic policy loops, and renderer sidecars are not part of the current implementation. Studio has one canonical loader, load_physics_input(case_json_path, result_path), and one dynamic public output, common_rollout.npz.
