+# Clean Test TsFile
+
+This dataset is an Apache TsFile conversion of
+[`sattgle/clean-test`](https://huggingface.co/datasets/sattgle/clean-test), a LeRobot v2.1 SO101 follower
+robot-manipulation dataset for the clean task.
+It contains numeric trajectories, timing, and episode/task tags. Videos remain
+in the original Hugging Face repository.
+
+## Source Dataset and Attribution
+
+- Original dataset: [`sattgle/clean-test`](https://huggingface.co/datasets/sattgle/clean-test)
+- Repository owner, uploader, and sole contributor:
+  [Hugging Face user sattgle (`sattgle`)](https://huggingface.co/sattgle)
+- License: Apache-2.0
+- Task: "clean"
+- Robot: `so101_follower`; LeRobot version: `v2.1`
+- Split: `train`; sampling rate: 30 fps
+- Scale: 50 episodes, 32,220 frames, 1 task
+- Source shards: 50 Parquet files totaling 1,680,276 bytes
+- Source frame layout:
+  `data/chunk-{episode_chunk:03d}/episode_{episode_index:06d}.parquet`
+- Paper, external homepage, and completed citation: not provided by the source card.
+
+The source metadata, all 50 Parquet shards, and episode metadata consistently describe this 50-episode dataset.
+
+## TsFile Dataset
+
+- TsFile: `data/sattgle_clean_test.tsfile` (718,233 bytes)
+- Table: `sattgle_clean_test`
+- Rows: 32,220; episodes/devices: 50; tasks: 1
+- Time precision: milliseconds
+- TsFile/source-Parquet size ratio: 0.427
+- `meta/` is preserved from the source, with only `meta/info.json` rewritten to
+  describe the TsFile schema and source-video alignment.
+
+## Schema and Mapping
+
+`Time = round(timestamp * 1000)` milliseconds. Time starts at zero and is
+strictly increasing inside every episode. The source `timestamp` is dropped
+afterward because it is represented by `Time / 1000` seconds at the selected
+precision.
+
+| TsFile column | Role | Type | Source mapping |
+|---|---|---|---|
+| `Time` | TIME | TIMESTAMP | `round(timestamp * 1000)` ms |
+| `episode_index` | TAG | STRING | Original INT64 episode index |
+| `task_index` | TAG | STRING | Original INT64 task index |
+| `frame_index` | FIELD | INT64 | Preserved |
+| `sample_index` | FIELD | INT64 | Renamed from `index` |
+| `action_0` ... `action_5` | FIELD | FLOAT | Flattened from `action[6]` |
+| `observation_state_0` ... `observation_state_5` | FIELD | FLOAT | Flattened from `observation.state[6]` |
+
+The six vector dimensions are `shoulder_pan.pos`, `shoulder_lift.pos`,
+`elbow_flex.pos`, `wrist_flex.pos`, `wrist_roll.pos`, and `gripper.pos`.
+Dots in source names are replaced by underscores. No numeric row, episode,
+task, state dimension, or action dimension is dropped.
+
+## Encodings and Compression
+
+- FLOAT/DOUBLE: GORILLA + LZ4
+- INT32/INT64: TS_2DIFF + LZ4
+- Time: TS_2DIFF + LZ4
+- BOOLEAN: RLE + LZ4 (the source contains no BOOLEAN field)
+- TAG: TsFile table/device TAG storage
+
+The physical table schema, every field codec, TAG roles, and all 32,220 rows
+were read back with the Apache TsFile Java API.
+
+## Videos
+
+Videos are not included in this TsFile repository. The source contains
+100 frame-aligned AV1 MP4 files (597,891,922 bytes), 640x360 at 30 fps with
+no audio, in two streams with 50 episode files each:
+
+- [`observation.images.front`](https://huggingface.co/datasets/sattgle/clean-test/tree/main/videos/chunk-000/observation.images.front)
+- [`observation.images.rear`](https://huggingface.co/datasets/sattgle/clean-test/tree/main/videos/chunk-000/observation.images.rear)
+
+The source layout is
+`videos/chunk-{episode_chunk:03d}/{video_key}/episode_{episode_index:06d}.mp4`.
+Use `episode_index`, `frame_index`, and `meta/episodes.jsonl` to align numeric
+rows with the original video frames.
+
+## Quality Checks
+
+Source Parquet, staged Parquet, and complete Java TsFile readback all contain
+32,220 rows. Scalar values, all flattened vector values, TAGs, episode indexes,
+Time mapping and monotonicity, physical codecs, size, and SHA-256 were checked
+locally. Conversion scripts and local quality-check reports are intentionally excluded
+from this upload-ready directory.
+
+## Minimal Read Example
+
+```python
+from tsfile import TsFileReader
+
+reader = TsFileReader("data/sattgle_clean_test.tsfile")
+with reader.query_table(
+    "sattgle_clean_test",
+    ["episode_index", "task_index", "frame_index", "sample_index",
+     "action_0", "observation_state_0"],
+    batch_size=65536,
+) as result:
+    batch = result.read_arrow_batch()
+    print(batch.to_pandas().head())
+reader.close()
+```
+
+## Citation
+
+The source card provides no personal name, paper, external homepage, or completed citation. Cite the original
+Hugging Face dataset and Hugging Face user sattgle (`sattgle`) when using this conversion.
