A near-black silver-gelatin Ritual Chamber production still, 4:5 portrait: a dormant agent cabinet stands alone in a tall slate service corridor, its front opened to a tiny phosphor-green wake-up relay. Three thin sensor threads arrive from a rain gauge, a stack of task receipts, and a weathered city map, all physically anchored to a low hex-lattice floor. Hard side light, large empty walls, an interlocking cream-and-dark institute tile high above. Numbered callouts mark the relay, sensor thread, and receipt inlet. A brass weather vane turns indoors beside one gloved hand. One small Bureau seal struck once, lower corner. No readable caption text. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
