LIBERO EDA Hosted Data

Immutable, browser-oriented data for the LIBERO EDA web application.

This repository contains:

• metadata for 130 Original LIBERO task families;
• browser replay metadata for 6,500 Original LIBERO demonstrations and 14,347 LIBERO-Plus training trajectories;
• gzip-compressed Arrow IPC trajectory series;
• 128 x 128 WebP thumbnails;
• derived Original LIBERO MP4 and MuJoCo GLB assets;
• content-addressed LIBERO-Plus evaluation geometry and source textures, plus numeric initial-state scene descriptors for all 10,030 evaluation conditions.

LIBERO-Plus training video is not duplicated. Replay manifests link to the pinned Sylvest/libero_plus_lerobot revision. LIBERO-Plus evaluation classification, BDDL, and init-state files are not copied; the application loads definitions directly from sylvestf/LIBERO-plus@4976dc30028e805ff8094b55501d532c48fec182. The distributed scene descriptors were derived with official state index 0, five zero actions, and a recorded environment/reset seed of 10,000. They retain source-relative paths and SHA-256 provenance. If robosuite rejects a transient constructor placement, the exporter advances the same seeded random stream without reseeding, matching LIBERO's reset rejection sampling, and stops after 100 attempts. The scene manifest also pins the simulator asset dataset to Sylvest/LIBERO-plus@dd2bd61b7d9a6fef1abc52d606e983b41886a149, records the source archive SHA-256, and requires the exact 448,799-file extraction before export. The extraction is matched to the official archive by path, byte size, CRC, and a deterministic content tree SHA-256. Symlinks and incomplete or modified extracts are rejected. The pinned tree digest (libero-plus-asset-tree-sha256/v1) is 6c4c2e638f6401304f01b2573c80af41b35b6d94838df71f6ab91f59468b7ecb.

Original LIBERO video is displayed in its recorded source orientation. The published LIBERO-Plus MP4 convention is rotated 180 degrees from raw LIBERO; each replay manifest declares that convention and the Replay UI restores the simulator orientation by default. The source pixels are not rewritten. The public LIBERO-Plus files are one MP4 per episode, so hosted v2 manifests use a zero-based interval from 0 to state_count / 20. The one-way v1-to-v2 migration verifies the older chunk-global interval length before normalizing it; video bytes are neither copied nor modified.

Evaluation scenes are interactive initial states, not screenshots, videos, or successful trajectories. Geometry is shared per Original LIBERO source task, and textures are deduplicated by content hash.

manifest.json is the small browser entry point for schema, counts, and provenance. It pins integrity/artifacts.json, which records every distributed file's byte size and SHA-256 value. Both are written only after a complete export.
