-## ✨ Data Highlights
-
-- **Optical Ground Truth** – Sub-millimeter accuracy (<1mm), 120 fps, no estimation errors.
-- **Dexterous Hands** – 20+ DoF per hand, synchronized with object 6D pose for fine-grained manipulation.
-- **Robot-Ready** – Pre-retargeted to Unitree G1; custom retargeting available on request.
-- **Real-World Diversity** – 15+ scenarios (industrial, household, retail, healthcare, logistics, agriculture, performance), 500+ tasks, 1000+ objects.
-- **Multi-Modal** – Full-body skeleton (BVH), finger motion, object pose, multi-view video, semantic labels.
-- **Quality Assured** – Every take passes automated cleaning + manual inspection; quality flags (pass/warning/fail) provided.

-## ✅ Quality Assurance
-
-All data undergoes a rigorous pipeline:
-1. **Marker swap correction** – automatic detection and repair.
-2. **Gap filling** – cubic spline interpolation for gaps ≤6 frames; longer gaps flagged.
-3. **Foot skating detection** – flagged when static foot drifts >2cm/s.
-4. **Manual review** – each take reviewed by trained annotators.
-5. **Quality flags** – `pass` (clean), `warning` (minor issues), `fail` (do not use).
-
-Typical accuracy:
-- Joint position error: <1mm (optical system limit)
-- Object 6D pose: ±2mm translation, ±0.5° rotation
-- Temporal sync between modalities: <1 frame
