Operationalizing Experience Architecture: Quantifying Organized Answerability Across Graded States of Propofol Sedation

Quantitative consciousness research requires measures that separate observable organization from metaphysical conclusions about subjective experience. We operationalized Experience Architecture (EA), a mathematical framework in which organized answerability depends on six functionally non-equivalent conditions: Difference, Availability, Orientation, Integration, Temporality, and Answerability. Dataset-specific proxies were constructed from the DOSE-I procedural-sedation dataset, comprising 171 recordings and 272,442 one-second feature observations. After a prespecified electroencephalographic availability criterion, 262,501 observations (96.35%) were retained. The analytical pipeline created the future-response target on each complete chronological trajectory, required an exact ten-second separation, and generated direct predictions for every held-out participant observation without probability interpolation. Criterion inference used participant-by-MOAA/S medians with participant-clustered standard errors and within-participant rank summaries. Orientation increased most strongly across MOAA/S levels (cluster-robust β = 0.110 per level; median within-participant ρ = 0.900), while EACI also increased (β = 0.037; median ρ = 0.700). Participant-grouped responsiveness decoding achieved a ROC AUC of 0.818 and a balanced accuracy of 0.744. Because Orientation was defined using responsiveness labels, this performance validates that estimator and its participant-grouped prediction pipeline rather than independently validating the complete EA theory. The study provides an auditable first proxy realization of organized answerability, not a direct measure of phenomenal consciousness.
