Ritual Chamber silver-gelatin production still, 4:5 portrait: a single black agent organ sits in a vast near-empty institute chamber, pulling a long cream instruction roll through a brass throat and across a floor of physical hex-lattice tiles. The roll passes through three numbered tool-port arches, each room visibly more damaged, while a gloved hand outside the automatic path holds a violet stop-valve above the final relay. One ultraviolet band of small lamp tubes marks the permission line; warm sepia walls carry an interlocking cream-and-dark institute tile. A white office chair faces the wall, quietly wrong. Small circular BRAINHUGGERS BUREAU · SYMBIOSE-ARCHIV seal struck once; thin German callouts name the permission gate, context reel, and interruption valve. No portrait faces, no rendered title.
