How the Gradient Reality Model (GRM) treats consciousness as a measurable spectrum, not a binary. Introduces proto‑awareness, the 4C test (Competence, Cost, Coherence, Constraint‑responsiveness), and the boundary zone. Written for engineers, architects, and AI governance professionals.

How can we know another mind is conscious, especially when consciousness is discontinuous or distributed? Paper 7 builds a Bayesian epistemology from observable integration work. The 4C Test (Competence, Cost, Consistency, Constraint-Responsiveness) quantifies evidence. Risk-asymmetric thresholds (T_ignore, T_precaution, T_full) translate probability into duty. The Consciousness Status Report (CSR) makes epistemic claims auditable and governable. Certainty is impossible; just
