walking_sample_v1

File	Description
data.jsonl	80 consecutive frames, one JSON object per line (primary person keypoints, optional layer11, source_video_fps, etc.).
features.json	Sequence-level aggregates (visibility, hip motion, motion_consistency, stride proxies).
global_stats.json	Job-level roll-up for this clip.
manifest.json	Metadata aligned with the Motion Dataset Engine export format.
export_quality_report.json	Pilot-oriented summary + pointers to formulas.

Coordinate system: normalized image coordinates (typically ~0–1 for x/y), z relative depth as exported by the engine.

Not included: raw video, full ZIP checksums, or rejected frames — this repo is intentionally small for GitHub hosting and feedback collection.
