"description": "A Physarum (slime-mould) organism grown in the Anisota Lab's Plasmodium workbench and saved to the owner's collection. Stored as its recipe rather than its pixels: a 'seed', the simulation 'gridSize', a 'genome' of behavioural parameters (all continuous 0..1 tunables scaled to integers 0..1000, since atproto lexicons have no float type), and the ordered 'foods' and 'inoculations' the grower placed. Because the GPU agent simulation is deterministic given the same seed, genome and placements, replaying the recipe regrows the organism. A small PNG thumbnail is kept for display."
