+# integration Data Collection Dataset
+
+Merged LeRobot v3.0 dataset: **100 episodes, 26,953 frames, 30 FPS**, robot type `so_follower`. Two 640×480 camera streams (`front` and `wrist`) and six-dimensional actions/state are preserved.
+
+All episodes are in the train split. Episodes and global frame indices are continuous. Task labels are preserved exactly and mapped into one shared task table. No episodes were deduplicated or dropped. Original video files are copied without re-encoding; video timestamps remain relative to their original files.

+## Statistics and provenance
+
+Numeric feature statistics, including quantiles, are recomputed from all stored frames. Image means and standard deviations are pooled from the original per-episode sampled image statistics. Image quantiles use LeRobot's conservative envelope aggregation (minimum for q01/q10/q50, maximum for q90/q99); they are not exact global pixel quantiles. Per-episode index statistics are recomputed after reindexing. Source commit revisions and index ranges are recorded in `meta/merge_sources.json`.
