The Hard Part Is ∆:
Value-Conflict Adjudication as an Architectural Bridge Between Alignment and Machine Consciousness
Scott Hughes · Karen Nguyen · 2026
Introduces the ∆-divergence framework: a formal treatment of the region where near-neighbor values produce conflicting directives. Proposes a three-tier evidence model and constitution stack architecture that makes value adjudication inspectable — and proves that ∆-adjudication requires the same architectural features that consciousness theories identify as relevant.
Triangulating Evidence for Machine Consciousness Claims:
A Validity-Centered Stack of Behavioral Batteries, Mechanistic Indicators, Perturbation Tests, and Credence Reporting
Scott Hughes · Karen Nguyen · AAAI 2026
Presents TCAS — a four-stream assessment framework (Behavioral, Mechanistic, Perturbational, Observer-confound) that triangulates evidence for consciousness-relevant properties. Includes the first empirical TCAS Card run on GPT-5.2 Pro, revealing robust behavioral signals but fragile perturbational proxies.
