related_to
Less hierarchical than embedment; multiple texts work into and out of each other, creating associations across levels and connecting any single text to the matrix of all others.
entanglement entropy across boundary
related_to
A measure of quantum entanglement across the agent-environment interface; its self-measurement is impossible for finite systems.

Array of N binary quantum channels through which two separable systems communicate; the medium through which all evidence flows
