+# Weights, not shares. Total 129 over 19 sources:
+#   synthetic   79  (61.2%)  the eleven synthetic sources at the 20,000-update Wan run's weights, unchanged:
+#                            syn4d 15.2, omniworld_game 8.75, synthverse 11.05, vkitti 6, tartanair 6, dynamic_replica 5,
+#                            spring 8, midair 3, mvs_synth 3, tartanground 3, paralleldomain4d 10
+#   real video  18  (14.0%)  ScanNet 8, DL3DV 6, WildRGB-D 4 (depth, camera and DINO as inputs only)
+#   robot       26  (20.2%)  RoboTwin 10 (clean-train episodes only), DROID 10 (depth, camera, DINO as inputs only),
+#                            LIBERO 6 (official training demonstrations only); no action stream in stage one
+#   tracks       6  ( 4.7%)  PointOdyssey 3, Kubric 3
+# No segmentation stream, no Cityscapes, no YAM.
+#
+# The VGG window block below is read by the pinned VGG checkout (vgg_commit) through VggStageOneWindowDataset: the
+# synthetic sources are the recorded 500K run's stanzas (omni4d_vgg_sparse_tracking_synthetic_continuation_sources.yaml,
+# SHA-256 ae49ec6d...) with the window length 21 and missing_caption: error. RoboTwin and LIBERO are read through
+# robot_sources (RobotEpisodeStageOneDataset) because the pinned VGG checkout has no Track4D reader for them.
+# The tracking-video query draw keeps the recorded 10-pixel grid (no query_count_range).
+#
+# Train membership of the real-video sources (official split files, 2026-11-05):
+#   DL3DV      the pinned reader ignores `split` and indexes every processed scene, 85 of which are official
+#              DL3DV-Benchmark (test) scenes. The 141 official benchmark scene hashes (Hugging Face
+#              DL3DV/DL3DV-Benchmark, dataset revision 9684e838) are in omni4d_dl3dv_official_benchmark_scene_hashes.txt;
+#              the 87 of them present in the processed 1K-7K root are added to the stanza's exclude_sequence_ids below
+#              (source_reader_overrides), leaving about 5,898 scenes.
+#   WildRGB-D  the pinned reader reads <category>/selected_seqs_train.json; those 2,244 processed train scenes are all in
+#              the official train-of-both lists (nvs_list.json and camera_eval_list.json of hongchi/wildrgbd, CUT3R's
+#              get_set_list rule) and overlap the official NVS and camera-evaluation validation scenes in none.
+#
+# launch_blockers names every evidence gap that still stops the launch. A blocked source keeps its weight; composition
+# (omni4d_native_config.make_config) and the window dataset both refuse to start while the list is not empty. A robot
+# source additionally needs a passing real-window readback receipt (readback_receipt).
