Add 50 demonstrations each for Task4-2, Task4-3, Task5-2 and Task5-3
DRAFT: upload and online validation are in progress. Do not merge yet.
Adds 200 raw HDF5 simulation demonstrations (50 per task), 764,822 frames, approximately 178.42 GiB. Preserves all 331 existing demonstrations; combined release contains 531 episodes and 1,748,580 frames.
The 37 required HDF5 fields remain compatible with the existing reader. External camera JPEGs are losslessly rotated to match existing public image orientation; wrist images and numerical arrays are unchanged. Internal path metadata is redacted. Optional simulator fields are documented. README, manifests, checksums and four task previews are updated.
Local checks passed for all 200 files. The unchanged raw2train pipeline and cfg09 DataLoader were exercised on four complete representative episodes. Online file inventory, checksums and download checks are pending.
Important: published external-camera orientation differs from the historical internal Task4/5 training videos; checkpoint reuse requires matching preprocessing. This is raw HDF5, not pre-normalized model training data.
Final merge into main requires dataset owner approval.
