The living organism (a11oy + killinchu) as a directed causal-dependency graph: an edge source→target means the target organ causally depends on the source. Each organ holds local homeostatic invariants. DEMO: kill an organ and watch downstream organs re-route around it while the surrounding tissue self-heals over discrete NCA-style steps. Vitals are LIVE where the in-process anatomy/mesh expose them, MODELED otherwise; self-repair is an EXPERIMENTAL explicit local rule (not a trained CA). Effectors SIMULATED — this heals a model of the organism.
