Co(Healthcare): Fusion‑Layer Decision‑Energy Geometry for Clinical Systems (Paper 10.2.2)

Paper 10.2.2 is the Fusion‑layer applied extension of Co(Healthcare) in the DCE 10.x Continuity Geometry series. It operationalizes Fusion‑layer continuity geometry through decision‑energy invariants, contradiction detection, clinical curvature reduction, and governance structures for healthcare decision systems. The paper defines the Fusion‑layer continuity metrics (DES, CDI, DCR, DAS, DPM), decision‑energy geometry, contradiction envelopes, escalation curves, contradiction invariants, and governance triggers. It provides implementation pathways, pilot designs, and evaluation frameworks for measuring Fusion‑layer continuity in clinical environments. Paper 10.2.2 is a non‑canonical sub‑extension of Paper 10.2. It does not modify the DCE substrate canon. It follows Paper 10.2.1 (Cyber+Fusion applied layer) and precedes Paper 10.2.3 (QC applied layer) in the Cyber → Fusion → QC triad.
