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.

Any valid record key
Properties
agentTier
integer
Optional
Agent-count tier that grew it (0=small, 1=medium, 2=large). A reopen may cap lower on a weaker device.

Required
When the organism was saved
foods
array
of
object
Optional
Ordered food drops the grower placed; each replayed at its step so growth rebuilds identically.
maxLength: 256 itemsgenome
object
Required
Behavioural parameters. Global tunables plus one species entry (two when multiSpecies). Continuous values are scaled to integers 0..1000; enumerated traits (spawn, interMode, renderMode) are small raw integer indices.

Trail-field grid resolution in cells (square)
