 - count, finite-value and maximum-point safety gates;
 - immutable point-aligned arrays;
 - a fail-closed K1 `lio_pcl` boundary;
+- a content-addressed `missioncore.k1-local-surface/v1` replay derivative over
+  immutable `RAVNOVES00`, with dynamic height/slope/roughness/confidence,
+  explicit pose-binding age and conservative observed occupied/unknown policy;
+- a provider-neutral read-only local-surface view in
+  **Парк → Диагностика LiDAR**, synchronized to the five existing
+  RAVNOVES00 scene selectors;
 - worker storage admission for `D:\NDC_MISSIONCORE\datasets` and
   `/mnt/d/NDC_MISSIONCORE/datasets`;
 - a dedicated, honest dataset catalog in **Полигон → Датасеты**;
