Canon: Diagonal (Var) marks cooperation within an agent—ordered signal-transduction that improbably maintains order against physics (Schrödinger’s “negentropy”). Off-diagonals (Cov) mark transactions between agents—synchronies that arise at interfaces. Collisions at h(t) stress Σ; the observed ΔS is what gets written into θ′.
Tip: rename A–E to concrete agents (e.g., Donor, Nondonor, Provider, Payer, Regulator) or subsystems within one organism if you’re modeling intra-agent structure.
