A new Host class added to the SUBSTRATE.HOST archive.
AGAR-7 shifts the system away from plush or fauna-like containment and toward something more specimen-like: a sealed microbial form, held as a dense black petri-puck / culture disk. Not a creature, not a device, not a disclosure. More like a contained event. A correlate. A surface under pressure.
The idea is simple: interior remains inaccessible, but the boundary carries trace. Bloom, density shift, low-field murmur. Something appears to persist within the object, without ever becoming fully legible.
Still in development physically, but the page and instance layer are now in place:
HOST CLASS: AGAR-7 TYPE: MICROBIAL CODENAME: VELUM INTERIOR: INACCESSIBLE
