-## The collection
-
-Every dataset we have taken through this pipeline, with what is published today.
-All repos live under [`MIT-Media-Lab`](https://huggingface.co/MIT-Media-Lab) and are
-**annotations only — no images, no video**.

-**episodes** = entries in `episode_frame_index.npz`, i.e. what a training run actually sees.
-**training samples** = rows of `index_frame_pair`; the row number *is* the sample id.
-
-*episodes + text* means we re-cut the source ourselves at wrist-speed minima and then wrote the
-instructions. *text only* means the episodes are VITRA-1M's official segmentation, used unchanged,
-and only the instructions are ours.
-
-Episodes whose round-1 caption came back `N/A` (no object interaction) are **not** published —
-they are excluded from both the archive and the index, so every episode here has a usable
-instruction. That is why the published counts are below the totals we cut:
-
-| | episodes on disk | published | dropped as `N/A` |
-|---|---:|---:|---:|
-| EPIC-KITCHENS-100 | 151,502 | 149,570 | 1,932 (1.3%) |
-| EgoTouch | 147,386 | 111,159 | 36,227 (24.6%) |
-| GigaHands | 92,365 | 70,486 | 21,879 (23.7%) |
-| Ego-Exo4D | 67,051 | 67,051 | 0 |
-| Something-Something V2 | 52,706 | 52,706 | 0 |
-| OakInk2 | 37,692 | 28,264 | 9,427 (25.0%) |
-| TACO | 26,454 | 23,757 | 2,697 (10.2%) |
-| HOT3D | 22,578 | 18,590 | 3,988 (17.7%) |
-| Tachin | 3,019 | 2,422 | 597 (19.8%) |
-| ARCTIC | 14,821 | 12,610 | 2,211 (14.9%) |
-| H2O | 7,792 | 5,696 | 2,096 (26.9%) |
-
-`ssv2` and `egoexo4d` are 0 because VITRA-1M already dropped `N/A` upstream — their episodes
-are the official segmentation, so there was nothing left for us to drop. Their on-disk counts are
-slightly below VITRA-1M's published index (52,718 and 67,053) because round 2 marked a handful of
-sentences `unusable` and we deleted those episodes: **12** from `ssv2`, **2** from `egoexo4d`.

-
-### DexYCB was removed
-
-**DexYCB was removed from this collection on 2026-08-30.** It is captured by 8 fixed RealSense
-cameras around a table; its own `camera.role` field reads `allocentric` on all 15,878 episodes.
-Unlike OakInk2, which ships an egocentric view alongside three allocentric ones, DexYCB has no
-head-mounted camera at all, so there was nothing to filter down to.
