"Chronic insomnia is characterised by persistent difficulty initiating or maintaining sleep, or early morning awakening, despite adequate opportunity for sleep, resulting in some form of daytime impairment. The sleep difficulty occurs at least 3 nights per week and has been present for at least 3 months."
No DCG enters the network alone. The human is not the inspector — the human is the rule of pairing itself.
Symbolic
Arity, domain consistency, fiber-internal coherence. No cycles, no contradictions.
Human
A licensed practitioner whose credentials are at stake. Confirms clinical truth.
Neural
Semantic alignment between prose intent and structured form. The reading must match.

The encounter
A clinician in São Paulo sees a patient. Within eight minutes, the network surfaces relevant DCGs from last month's Lima cluster; a boundary marker flags a population subgroup; the decision is informed without disrupting the consultation.

Institutional refinement
The clinic notices a pattern: a community-validated rule shows different effectiveness here. A refined DCG is proposed; 23 peer clinics test it; 18 confirm, 3 partial, 2 no match. Consensus is reached. The boundary sharpens.

Federated propagation
The validated refinement propagates globally. No data crosses borders; only structured judgment. A boundary discovered in Lagos sharpens treatment in Lima. Each propagation requires multi-institutional consensus — nothing imposed.
