Document hosted v2 text coverage

Keep only v2 text annotations; add MotionMillion v2 test sidecars

Add object-preserving Qwen3-0.6B caption rewrites v2 for HiPHI/OMOMO/HUMOTO

Add ncsa/objects (meeting-room chair mesh + per-session poses)

ncsa: ground_v1 sidecars (session-pooled floor heights; ncsa was missing from ESTIMATED_GROUND_SOURCES)

NCSA: publish v3 (GVHMR labels) + refresh meeting-room manifests, drop v1 variants

Add calibrated NCSA meeting-room 2pt and 3pt datasets

README: hiphi/canonical_objects now 40 assets + 40 mirrors

hiphi/canonical_objects: 61 -> 80 meshes (all base + __mirror), mirror rows recomputed on mirrored geometry

hiphi/humoto canonical_objects: 2026-09-15 canonical frames (upright, bbox-aligned, front +z); README rows

omomo/canonical_objects: 2026-09-15 canonical frames (all 15 assets + mop/vacuum bottom parts, upright + bbox-aligned + front +z); README row

Add DIP-IMU per-clip ground-plane sidecars

Add MotionMillion per-clip ground-plane sidecars (part 4)

Add MotionMillion per-clip ground-plane sidecars (part 3)

Add MotionMillion per-clip ground-plane sidecars (part 2)

Add MotionMillion per-clip ground-plane sidecars

Remove raw/ (legacy pickles are not hosted); update card

Copy files from datasets/TianhangCheng7/IMU4DData_private

Rename motionmillion/full_wds_v1 -> v1; move imuposer/legacy_v1 -> raw/; remove DIP-IMU (private repo only); update card

Move imuposer/legacy_v1 -> raw/imuposer/legacy_v1 (server-side copy, step 1/2)

Move motionmillion/full_wds_v1 -> motionmillion/v1 (server-side copy, step 1/2)

ncsa: v1 = T-pose-only calibration (was v1_tpose); oracle heading variant -> ncsa/v1_heading_fix_by_visual_oracle

Copy files from datasets/TianhangCheng7/IMU4DData

humoto: processed/humoto/v1 is now the WDS (was unified_v1); legacy pickles moved to data/raw, no longer hosted

README: ncsa/v1_fixed renamed to ncsa/v1

Rename ncsa/v1_fixed -> ncsa/v1 (delete old path)

Copy files from datasets/TianhangCheng7/IMU4DData

README: only ncsa/v1_fixed

Remove ncsa/v1 (handoff conventions, wrong acc sign/heading) and ncsa/v1_tpose (eval-only variant); keep ncsa/v1_fixed

TEMP: dipimu/v2 (to be removed)

README: drop imuposer/v1

Remove superseded imuposer/v1 (v2 is the only supported version)

README: imuposer/v2, ncsa variants, canonical_objects

Add imuposer/v2, ncsa/{v1,v1_fixed,v1_tpose}, omomo/canonical_objects (part 2)

Add imuposer/v2, ncsa/{v1,v1_fixed,v1_tpose}, omomo/canonical_objects

README: point DIP-IMU to private companion repo

Dataset card: drop zip reference

Remove imuposer_dataset_processed.zip (identical to imuposer/legacy_v1)

Dataset card: IMUPoser WDS, DIP-IMU not included

Remove DIP-IMU (license does not permit redistribution)

Dataset card: layout
