OptionaldiagnosticsFull CSG / opening diagnostics aggregated by the native geometry pass
(ProcessingStats.geometry_diagnostics) - the same GeometryDiagnostics
contract the WASM batch path surfaces. Present only when the native helper
reports it (and only when non-empty); the streaming loader forwards it onto
the complete event so the native-only viewer surfaces the same diagnostics.
