+
+## semantic_patch_cache_vrsbench
+
+- **Dataset:** VRSBench (512×512)
+- Caches do **not** store precomputed global tokens or patch orientations.
+- **Gaussian parameters** and patch metadata **are** stored.
+- **No need to regenerate** `.pt` files — HeatTok computes global tokens and orientations online at load time.
+
 ---
+
+## semantic_patch_cache_earthvqa
+
+- **Dataset:** EarthVQA (1024×1024)
+- Caches use **global downsample divisor 1** (`gd1`).
+- To use **divisor 8** (`gd8`), no regeneration needed — global branch is rebuilt online from the image processor.
+
