 ## Known caveats
 
-- **Missing episode**: `motherboard/2026-05-11/episode_001` was lost at recording time (HDF5 superblock never finalized when the writer was killed mid-write). It is intentionally absent.
+- **Missing / dropped episodes** on `motherboard/2026-05-11`:
+  - `episode_000` and `episode_002` — short test recordings (8.8s and 10.4s) with no tactile contact on either sensor; intentionally excluded.
+  - `episode_001` — lost at recording time (HDF5 superblock never finalized when the writer was killed mid-write); intentionally absent.
+  - The remaining episode IDs are non-contiguous as a result. Don't infer ordering from filename gaps.
 - **Lossy resize**: the 128×128 `view` and tactile fields are downsampled from native 480×640. Native resolution is **not** preserved in this release.
 - **Single camera**: only `realsense/cam0/color` is included. The other two RealSense views and all depth streams are not in `processed/mode1_v1/`.
 - **OptiTrack alignment**: the per-step poses are nearest-neighbor matched to camera ticks. The full ~120 Hz pose streams are not preserved here.
