Add one display case in the marked empty intervention area.\n\nUse meters and Z-up coordinates. Return executable Python only. Save the final scene to /output/scene.blend.\n\nThe numerical clauses below and the attached public JSON contract define the native checks. Unobserved geometry is not a unique reconstruction target. Semantic category, materials and visual finish remain separate requirements; native geometry scores do not certify them.\nClosed-solid interiors count as occupied, independently of object names, partitions and global normal reversal. Deduplicate geometric triangles at 7 coordinate decimal places and retain their direction sets, never direction counts. A face present in both directions has no orientation anchor. Complete coherent closed-shell normals topologically using consistent single-direction anchors; inconsistent anchors use solid parity and cannot create a cavity. Strictly nested coherent shells with known opposite orientation denote a cavity only when their boundaries do not touch or intersect. If bidirectional duplicates erase a nested shell orientation, an ambiguous solid/cavity result is unknown and cannot establish empty space. A lone closed shell remains solid without orientation anchors, and an independent positive solid cannot be erased by an unknown cavity. Open boundary sheets are peeled for occupancy only and still count in surface intersections. Nonmanifold cores cannot establish empty space within the connected core bounds. Diagnostic duplicates do not alone fail inspection; they do not guarantee that cavity orientation remains decidable.\nCandidate format: save a native Blender scene using meter units (unit scale 1, tolerance 1e-6). Evaluated vertices must be finite with each absolute coordinate at most 10000 m; triangles must be nonempty valid integer vertex triples, at most 2000000; at most 20000 object datablocks. Hidden geometry is included. External linked libraries, object drivers, unpacked file images, non-meter unit scale and unknown inspection issues are fatal. Duplicate triangles are diagnostic only: the extractor rounds coordinates to 5 decimal places, ignores winding and reports duplicate_triangles above a 0.005 duplicate fraction; this alone does not fail a native candidate. Malformed/empty/nonfinite candidate geometry is an invalid submission, not a measured geometric success. Infrastructure failures receive no model score. Resource limits still apply.\n\nPreserve geometry outside the public intervention region according to the public protocol below.\nOutside the allowed edit box expanded by 0.03 m, every triangle surface point must be within 0.03 m of the other mesh in both directions. Exact matching faces or adaptive convex triangle distance bounds establish preservation; a witnessed excess fails. Unresolved distance bounds after 18 subdivision levels or 250000 examined pieces per direction produce unknown, never a pass. Numerical guards scale with the largest coordinate; this is a conservative floating-point geometric check, not a formal arithmetic proof. Names, object grouping, overlap multiplicity, and predictable sample locations confer no preservation credit.\n\n- [ ] envelope: All evaluated geometry must remain inside the public bounding envelope [-10.785, -9.73, -0.25] to [10.785, 9.73, 4.05], with 0.16 m contact tolerance.\n- [ ] floor-0: Provide floor support at elevation 0 m over rectangle [-10.785, -9.73] to [10.785, 9.73]; boundary inset 0.06 m, elevation tolerance 0.035 m.
