+
+Snapshot of **35 completed Sim2 trajectories**, each with three verified appearance versions.
+Contains **105 appearance episodes**, **315 synchronized camera videos**,
+and **105 joint videos for inspection**. The ongoing campaign starts from 150 source
+demonstrations and evaluates 10 physical candidates per demonstration; this folder is a snapshot
+of completed results, not a claim that all 1500 candidates or all render jobs are finished.
+
+Each `episodes/<source_id>/appearance_00..02/` contains `head_rgbd.mp4`, `left_wrist_rgbd.mp4`,
+`right_wrist_rgbd.mp4`, `three_views.mp4`, `aligned_actions.npz`, appearance/source metadata,
+and assembly/quality receipts. `case.json` gives portable paths relative to this folder.
+Final acceptance is recorded in `case.json` and `quality_review.json`; `episode_receipt.json`
+preserves the historical assembly-stage status.
+
+Videos retain the complete original-speed trajectory at 24 fps and 224×224 pixels per camera.
+The joint inspection video is 672×224, ordered head / left wrist / right wrist.
+`aligned_actions.npz` contains `desired_command` (columns named by `joint_names`), `qpos`,
+`qvel`, `ctrl`, video/physical/state/command timestamps, and original source indices.
+All three appearances of a trajectory use the same action array.
+
+Blender/Cycles runs on CPU with 64 samples, denoising, three area lights, and stone,
+matte-laminate or photographic-wood table surfaces. Environment tones are guided by the
+paired Real1 head image. Task geometry and recorded motion are preserved; the head optics
+cover the task workspace, and native wrist optics are retained. The drawer has four levels
+and operates the second drawer from the bottom. Native CAD detail and simulation assumptions
+are retained; these videos are synthetic renders rather than hardware measurements.
+
+Every exported episode passed complete geometry/camera/action-clock and encoded-video checks.
+Each triplet also passed independent comparisons with the original rollout and issued commands.
+Only complete verified triplets are included. No Seedance outputs or incomplete/uncertain cases
+are included. `manifest.json` lists cases; `checksums.json` gives SHA-256 and byte counts.
