+  - Landed in `3613d393`: `LandblockPhysicsPublisher` now owns captured-origin
+    terrain/cell/portal/building physics, cached GfxObj shapes, mutually
+    exclusive multipart BSP or Setup fallback collision, exact static-owner
+    replacement, final reflood, demotion, and full removal. Every Setup shape
+    shares the retail logical entity ID; building shells remain exclusive to
+    the per-landcell building channel. Reapply retires stale cell/building/UCG
+    state and omitted static owners by landblock prefix, rebinds `CurrCell` to
+    the replacement object, and preserves adjacent owners even when collision
+    footprints cross the seam. Three corrected-diff reviews are clean. Release
