Synchronize V8 force for all218 episodes including validation; preserve accepted actions

Accept 274 short mocap repairs and 7 supported LOW patterns; preserve raw force and aligned targets

Repair mocap actions across all tasks, old_data and validation; retain V8 force

validation: the renumbered segments gain frame_index, the last of the LeRobot index columns they shipped without

validation: add the 2026-09-09 17:20/17:41 motherboard segments, renumbered 004-008; merge the indices

validation: publish poses and extrinsics Z-up, like the rest of the dataset

fix(validation): recompute force from the published tactile mp4

validation: add the LeRobot index columns the published folders carry

validation: ['meta', '2026-09-09']
