 transform raw `spatial.evidence.v1` RF Gaussians or `ruview.lidar.depth.v1` packets:
 neither supplies the independently tracked manipulation scene this method needs.
 
+The injected broker is trusted executable code, not sandboxed by this adapter.
+The no-network/no-actuation behavior applies to this adapter and the reviewed
+companion broker. Before reading scene markers or calling the broker, the adapter
+checks the entire snapshot as bounded plain JSON using property descriptors.
+It rejects proxies, getters, inherited/custom prototypes, nonfinite values,
+sparse arrays and non-JSON data, including nested values. Structural limits match
+the reviewed companion: depth 12, 20,000 values, 1,024 array elements, 64 object
+properties, 128-character keys and 4,096-character strings. Full geometry,
+provenance-label and signing-key validation remain the companion broker's responsibility.
