Aesthetic Integrity Index (AII) for human–AI hybrid epistemology: Reconfiguring the Beholder’s Share through Xie He’s Six Principles

• Establishes an evaluation framework for human–AI collaborative systems in the era of hybrid intelligence. • Introduces the Aesthetic Integrity Index (AII), a quantitative model that reconfigures the Beholder’s Share as an epistemic negotiation process by operationalizing Xie He’s Six Principles as cultural reasoning benchmarks. • Employs a non-compensatory additive–multiplicative structure integrating aesthetic fidelity (TASc = 0.6723), cultural anchoring (CAF = 0.0900), and calibrated agency (AAC = 1.0200), yielding an AII score of 77.75 that reflects balanced human–AI co-agency.
