Ritual Chamber, negative silver-gelatin film still: a near-empty East-German institute chamber contains a black-glass merchant control altar, a bright paper ledger, product cards, supplier tags, return parcels, and one ignored phosphor-green fraud lamp. A hexagonal honeycomb lattice forms the floor beneath the apparatus; one gloved hand adjusts a cashflow tube while robed backs remain in deep shadow. Hard warm tungsten key, near-black walls, cream-and-dark stepped-cross institute tile behind the ledger, one concentrated green vial band. Numbered callouts identify the ledger valve, fraud lamp, and return chute; the quietly wrong detail is a tiny receipt feeding back into the supplier drawer. One mis-struck circular Bureau seal.
