A negative silver-gelatin Ritual Chamber production still, 4:5 portrait: a black operations cage holds a pale autonomous office-worker specimen before a recessed evidence cabinet in a near-empty institute room; gloved hands feed paper test cards through its side slots. A hard oblique key leaves deep near-black walls, while cream-and-dark interlocking institute tiles run across the far wall and a physical hex-lattice floor carries the cage. A tight signal-cyan band of diagnostic tubes is the only accent. Numbered callouts mark a policy probe, independent-judge aperture, and evidence-receipt chute. An expired visitor badge lies inside the cage, the quiet error. One small Bureau seal struck once, lower right. No literal folio label or caption. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
