 An episode generally starts at `manifest.json` and has `scene/`, `cameras/`, `views/`, `logs/`, `annotations/`, and `validation/` as applicable. Under a selected camera's `views/<camera>/`, the `white/`, `mixed/`, and `colored-obb/` directories hold proxy media and prompts. Where supplied, the RGB appearance reference is in `views/<camera>/prompt-context/first_frame.png`. Each multi-view camera also has `views/<camera>/visibility.json`: per-frame visibility measurements for the four participants. A case may have a named version subdirectory; follow its manifest and local metadata rather than assuming all cases have identical leaves.

 ## Provenance and scope
 
-The uploaded tree preserves the **22,781 relative file paths** of the source `PROWBench-release/episodes/` directory and adds six Parquet Viewer indexes plus **40 multi-view `visibility.json` files**. The visibility files were copied byte-for-byte from `PROWBench-release/eval/annotations/multi4-<id>-<case>/<camera>/visibility.json` into the corresponding episode views. Their SHA-256 hashes, camera IDs, and 150-frame arrays were checked against the source evaluation bindings; all 40 have matching camera and OBB/depth inputs under the source `inputs/multi_view/` tree. `visiblePixelCount` measures pixels of the drawn participant box after depth testing, not a person segmentation mask. The source depth maps are not included here.
+The uploaded `episodes/` tree has the **same 22,821 relative file paths** as the local `PROWBench-release/episodes/` directory: the original 22,781 files plus **40 multi-view `visibility.json` files**. The six Parquet Viewer indexes are separate under the root `splits/` directory. The visibility files were copied byte-for-byte from `PROWBench-release/eval/annotations/multi4-<id>-<case>/<camera>/visibility.json` into the corresponding episode views. Their SHA-256 hashes, camera IDs, and 150-frame arrays were checked against the source evaluation bindings; all 40 have matching camera and OBB/depth inputs under the source `inputs/multi_view/` tree. `visiblePixelCount` measures pixels of the drawn participant box after depth testing, not a person segmentation mask. The source depth maps are not included here.
 
 To make the source directory usable by itself, **2,926 symlinks** that originally pointed to the sibling `.shared/` store were replaced with their target file bytes at the same paths, and **2,907 metadata files containing shared references** were expanded into ordinary JSON/JSONL content. Other copied files were checked against their source hashes. This is a standalone, materialized form of the episode tree; metadata files that contained shared references are not byte-identical to the compact source files.
