+# session_20260921_230446_039759: C6a proposal review
+
+**Status: agent proposal; owner mask/window/contact decisions pending.**
+
+Object: taped round belt. Motion: right-handed lift completely off the table on the major axis, allowing object to pivot relative to grasp and compress against the table, then place down.
+Current packet anchor converted frames: **256–682 inclusive**.
+Current packet endpoint sync timestamps: `1790046320273324755` / `1790046334519685694` ns.
+Participating identities: `hand_A`; A is the right, bracelet-wearing hand, B the left.
+Hands mean visible bare forearm through fingertips, excluding bracelet/sleeve. Occluder means the whole visible person, including clothing, accessories and nonparticipating hands.
+
+C1 evidence: `/mnt/data2/magna/belt_perception_shared/phystwin_model_corpus_expansion/lab/session_20260921_230446_039759/window_proposal_c1/proposal.json`.

+The newest completed media for each view/role currently present are listed below. A correction directory may cover only its changed views/roles; its media_index.json lists the exact coverage. Earlier prompts, propagation runs and media remain on disk. A new correction can make an older media directory historical; use current supplier admission before signoff or downstream processing.

+## Decisions and downstream boundary
+
+This card records the decisions above and grants no additional stage. Actual owner mask/window decisions must be recorded before final tracking. The three pushes also require an explicit decision about the fixed material-attachment approximation. After prompt corrections, perform fresh current-input admission; an old fitting identity alone does not detect every C1 F3 correction.
+
+C6a review findings and decisions are collected under `lab/c6a_20261027/`; source C1 records and protected A/B inputs remain unchanged.

Four initial prompt records and overlays were empty after the17:05:11 reboot. This new directory uses the same copied frame product, source window and exact agent prompt coordinates. No boundary, role, model or solver setting changed. All owner decisions remain pending.
