Record exact-revision Hub validation after trimming episode 819. The remote files match the validated build, LeRobot loads all metadata and tabular data, and the referenced video payloads are unchanged.
Remove the first 0.4 seconds (12 frames) from episode 819, including the isolated -443.956 degree wrist_flex state reading at 0.2 seconds. Rebase the episode timestamps and frame indices, shift subsequent global indices, advance all five video start offsets without re-encoding, and recompute numeric and visual episode/global statistics.
Record LeRobot visualizer compatibility validation
Losslessly rewrites the single episode-metadata Parquet from 1,200 one-row groups into one row group. Schema, row order, and all values are unchanged; the smaller physical layout prevents browser crashes in the LeRobot dataset visualizer.
Records byte-level checks of the published metadata and data, LFS identity checks for all 30 copied video shards, LeRobot loader smoke tests, and a complete decode of one newly mapped AV1 video shard.
Server-side copy of 15 camera video shards from justintiensmith/MT_State_Recognition_40. The source payloads were copied without re-encoding; two now-unreferenced target shards per camera were reused and one new shard per camera was added.
Replace the 200 State Recognition task strings with generic, explicit-open, and explicit-upside-down prompts. Hold closed and upright out of fine-tuning language; retain all trajectories. Add prompt_manifest_v2 CSV, JSONL, XLSX, and validation reports. Rebuild task indices without changing videos.
