 - Director timeline seeks cross the dateline along the short longitude arc.
 
+- Frequently reused terrain batches retain their cached heights ahead of unused cells.
+
 - Recent Imagery’s exported `setBox` and `searchHls` reject missing, blank or
   boolean programmatic box edges instead of interpreting them as zero coordinates.
