Remove four S20 episodes selected during manual video review: `episode_000007`, `episode_000011`, `episode_000015`, and `episode_000033`.
The change deletes all three camera views for each selected episode (12 MP4 files), removes their trajectory-index rows, and updates task metadata, the dataset manifest/checksum, and README counts. S20 retains 31 episodes / 93 videos, with 25 train and 6 validation samples. Dataset and split versions become 1.4.1.
Original episode numbers, all surviving train/validation assignments, and other tasks are preserved. Dataset totals become 1,007 trajectories (803 train / 204 validation) and 2,703 videos.
Validation: all 12 removed video hashes and sizes match the reviewed revision; all 93 retained S20 video references resolve with matching hashes; retained metadata rows and other task records are unchanged; JSON, counts, split membership, and the trajectory-index checksum are consistent.
Add State repeated-pouring anomaly S20 (35 trajectories)
Add S16–S19 from the 2026-11-03 PiperX collection: 137 unannotated trajectories and 411 frame-exact three-view videos. Exclude the reviewed tea #0/#1 and upside-down-cup #0 recordings; correct the bottle instruction to three bottles. Add 109 train / 28 val samples and preserve all existing S11–S15 files and frozen splits. Dataset/split v1.1.0: 9 tasks, 323 trajectories, 257 train / 66 val. No provenance files.
