# One finished capture -> the public HF dataset `initialneil/DREAMS-AVATAR`.
#
# Published set (10): P1C1 P1C2 P2C1 P2C2 P3C1 P3C2 P4C1 P4C2 P5C2 P6C2
#   C1 = train, C2 = test. P5/P6 are cross-reenact DRIVING only, so only their C2 ships.
#   P5C1 does not exist; P6C1 is excluded on purpose (stage_capture.py refuses both).
#
#   1. stage      hardlink frameset-videos/NN.mp4 -> staging/data/<PxCy>/videos/camNN.mp4,
#                 copy cameras.json, write capture.json
#   2. smplx      hmt_seq_out/smplx/*.npz -> staging/data/<PxCy>/smplx.npz (verified lossless)
#   3. previews   hmt_seq_out/grid_f*.jpg -> staging/previews/<PxCy>_f*.jpg + preview.jpg
#   4. metadata   rebuild staging/previews/metadata.jsonl over ALL staged captures
#   5. upload     small files in one commit, then the mp4s via resumable upload_large_folder
#
# The tracker's output dir is only ever READ.
# Re-runnable: safe to re-run after a network drop, the large upload resumes.
