Product development rarely moves forward through one perfect answer. It moves through traceable decisions. RHXY connects Plan, Sim, and Render as an engineering decision loop.
Plan
Plan should produce a requirement graph: user context, constraints, interfaces, manufacturing assumptions, risks, acceptance criteria, and verification method.
Sim
Sim should produce an evidence package: load cases, material assumptions, solver provenance, mesh quality, field outputs, quantities of interest, and credibility level.
Render
Render should produce shared scene state: model version, camera, material, lighting, review question, and decision context.
When these outputs share requirement IDs, geometry versions, material assumptions, and evidence links, they become learnable engineering episodes rather than disconnected assets.
