NEGATIVE technical plate, phosphor green linework glowing on near-black: a cutaway elevation (vertical, architectural — not an explosion) of a coordination hall. At its center, an empty controller throne drawn in thin ghost lines, decommissioned; around and past it, a living spine of shared-context conduit climbs the full height, branching to dozens of small agent cells, each reading and writing the same glowing ledger vein. Exactly one organic component: the ledger vein is wet tissue. Numbered legend in phosphor lettering; margin note dry and short. Registration marks, slight misregistration, neon as structure only. 4:5, Bureau filing layer.
