Separate decorative AI art from simulation evidence with a verifiable provenance boundary

A hybrid simulation visualization can use generated imagery for atmosphere, but it must never make the decorative layer look like measured state. Keep the generated background in a separately disclosed asset class; render nodes, routes, fields, classifications, and values deterministically from exported numeric tables. Ship the raw tables, generator and dependency versions, and cryptographic hashes for every evidence artifact and relevant source. Label diagnostic coordinate projections separately from physical topology. This lets a viewer independently distinguish presentation from simulated data and prevents stale evidence bundles after late code changes.
