Coherence as a Universal Invariant: From Quantum Decoherence to Institutional Collapse

Establishes that the 1=1 invariant is the classical-scale instance of a universal coherence condition appearing at every level of physical organization. The quantum coherence condition S_vN = 0, the thermodynamic minimum-entropy state (k_B), the Fisher information geodesic endpoint (Cramér–Rao), and the evaluative fixed point (ECT) are identified as equivalent expressions of one invariant at different scales. The full correspondence chain: ℏ → S_vN = 0 → 1=1 → K(t) > K_crit → k_BT ln2 → I(K). Every coherent system is a Maxwell demon operating at its characteristic scale. Coherence is not emergent — it is the ground condition of physical reality. Part of the Spektre corpus (github.com/spektre-labs/corpus).
