Ritual Chamber, silver-gelatin archival film still, 4:5 portrait: a near-empty institute inspection room with one immaculate research report suspended above a deep black verification chamber, all built around a physical hexagonal floor lattice. 01 a thin phosphor-green evidence filament runs from the report to a source shelf; 02 a red inspection shutter blocks the release slot; 03 a gloved hand holds a small black comparison lens. A large cream-and-dark stepped-cross institute tile recedes on the rear wall, while a row of green vials provides the lone accent. The quietly wrong detail is a child-size rubber stamp sealed inside the chamber. Bureau seal struck once lower right, numbered callouts inside the frame, strong tube-warm chiaroscuro, no faces.
