The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

MIND converts living mycelium networks into universal, self-repairing, biosensors.

C2weakest assumption

That the mycoponic ceramic size-exclusion nutrient delivery sustains mycelial metabolism and electrophysiological responsiveness over months without introducing confounding signals or metabolic artifacts that would invalidate stimulus classification.

C3one line summary

MIND integrates mycoponics with mycelial electrophysiology to create a multimodal biosensor that sustains function beyond 11 months, distinguishes 14 stimulus classes, and self-repairs within 72 hours across multiple fungal strains.
