Who actually reaches for this.
Unreal Blueprint Integrator makes Blueprint assets reviewable as deterministic local evidence and exposes a governed mutation surface. Blueprint/DataAsset materialization uses the same safety interlock for add_variable, set_cdo_property, and upsert_data_asset.
UBI 1.2.4 exposes the evidence pipeline, scoped read-only Blueprint compiler diagnostics, and FUbiMutationAssetOps for validated concrete changes. Preview remains read-only; apply requires a matching token, mutation profile, backup or explicit created-asset state, transaction, save, and audit; rollback restores backups or removes only the asset created by that operation.
