FOLIO A Ritual Chamber, silver-gelatin production still under a phosphor-green field: a frontal institute tableau where a company memory-organ rests on a pedestal, built from stacked Markdown sheets, YAML label tabs, and copper link-capillaries. Folio A institute tile covers the floor and rear wall; the hex lattice is carved into the pedestal grille. One small Bureau seal is struck on the bottom filing block. Numbered callouts identify 1 frontmatter membrane, 2 graph vessel, 3 agent-readable scar. One detail is quietly wrong: a filing drawer breathes in the corner.
