2026-05-15: hand+object Z-axis Gaussian smooth (σ=5 frames, MAD outlier reject) (4/8)

2026-05-15: refresh 11 mask-drift clips with hand-proximity init_frame penalty (2/11)

2026-05-15: refresh 22 mask-drift clips (Q1×2 outlier penalty + new init_frames + D-track) (8/22)

v1.11: pure canonical_scale (hf_reference simplified). No ICP / Umeyama / sanity refinement. Mesh scale = SAM3D canonical_scale directly; R = canonical_rotation_quat; per-frame translation = obs centroid + Gaussian smooth.

v1.10: restore original 5-stage tracking (estimate_anchor_pose FGR+ICP+Umeyama + track_6dof flow propagation). 40/225 oids get full 6DoF tracking; rest fall back to centroid translation + identity rotation. Scale closer to A100 reference (cereal box 0.219 vs reference 0.263).

v1.9: scale_correction is now ABSOLUTE (PLY units→world m, matches A100 reference convention). Robust min-enclose algorithm: per-axis [2,98]% pre-filter + median over axes of per-axis 90% enclose (depth-fringe-resistant)

v1.8: tracking uses SAM3D canonical_rotation_quat (per-clip initial orientation) + min-scale-95% enclose algorithm; object_pose.bin now reads pose_track_info.T_seq (full 6DoF tracked pose, not stale PCA OBB)

Step 1 full re-run @ 15fps with compound+fallback prompts and containment merge (55 clips)

Re-export 21 clips: scene.json objects/[] now populated from sam3_obj_data when no SAM3D mesh; silver-can clip uses 'silver can' instead of 'can of olives' (SAM3 hits 4/4 vs 3/4)

Replace samples/ with 21-clip Step 1 test batch (no SAM3D, no 6DoF)

Refresh dataset: 48 trim-reviewed clips, manual SAM3 prompts, full descriptions in scene.json
