+# session_20260921_232822_920324: selected-window mask review
+
+**window and masks accepted; reference input preparation pending.**
+
+Owner-selected anchor camera 12540311 converted frames: **331–765 inclusive**.
+Object: grey timing belt. Motion: right-handed grasp lifting completely off table, tilt hand and object together and compress against table, then put down.
+Participating controllers: `hand_A`. A is the right bracelet hand; B is the left hand.
+Hand masks cover visible bare forearm through fingertips and exclude sleeve/bracelet. The occluder covers the whole visible person, clothing, accessories and nonparticipating hands.
+
+[Recorded owner window decision](owner_window_decision.json) and [2026-10-28 owner mask review](owner_mask_acceptance_c6a_selected_20261028.json). Accept the reviewed object, hand_A, hand_B and whole-person occluder masks in all four cameras on the owner-selected window for reference input preparation. Prior, appearance and push fixed-attachment decisions remain separate.
+
+## Four-camera tiled videos
+
+Each video shows all four cameras in a 2×2 layout: **12540311 / 12933256** above **17736741 / 23007103**.
+
+[Object](review_tiled_c6a_20261028/role_object.mp4) · [Right hand A](review_tiled_c6a_20261028/role_hand_A.mp4) · [Left hand B](review_tiled_c6a_20261028/role_hand_B.mp4) · [Whole person](review_tiled_c6a_20261028/role_occluder.mp4)
+
+Playback is 10 frames/s for inspection. Views are associated by recorded timestamps; every native capture appears, with repeated tiles where needed. Labels show each camera’s selected-local, converted and native frame numbers, capture timestamp and offset from the display event. This is a display association, not a change to the masks or selected windows.

+Clips play every selected capture at 10 frames/s and retain the source capture timestamps. The first label uses selected-local `t`; each camera has its own count. The native mask arrays remain unchanged in the source packets.

+## Existing evidence and remaining review
+
+[Earlier packet and boundary context](/mnt/data2/magna/belt_perception_shared/phystwin_model_corpus_expansion/lab/session_20260921_232822_920324/window_anchor0308-0775/C6A_REVIEW.md) remain available; their old interval is historical. The existing mask quality findings remain relevant where their captures are retained. A trim does not correct mask defects or constitute a new full-playback mask review.
+
+
+[Reference review complete](/mnt/data2/magna/belt_perception_shared/phystwin_model_corpus_expansion/lab/session_20260921_232822_920324/window_anchor0331-0765/accepted_input_preparation_c6a_v1/review_v1/REVIEW.md). Initial geometry supports the current ribbon prior. Sample406 retains a displaced camera23007103 tail up to192.647mm from other-view support, with positional visibility retained. No corrections applied.
+
+window and masks accepted; reference and initial prior reviewed; owner prior acceptance pending; later sample406 depth tail retained.
+
+Owner accepted this exact initial ribbon prior on 2026-10-28 for surface-only mechanical inputs and reference static appearance. The disclosed geometry and later sample406 tail remain unchanged. Appearance acceptance and physical fitting remain separate.
+
+The appearance review is complete; owner acceptance is pending. [Review packet](accepted_input_preparation_c6a_v1/APPEARANCE_REVIEW_c6a_v1.md). Physical fitting remains outside scope.
+
+Static appearance is owner accepted. [Mechanical input review](accepted_input_preparation_c6a_v1/supervision/review_c6a_v1/MECHANICAL_REVIEW.md) is complete: all25 checks passed and both figures inspected. Later reference measurement limitations remain; no physical fitting ran.
