HγC O5: Calibration Consolidation for Structured Near-Critical Populations in Galactic Phenomenology

This paper establishes the first calibration-consolidation layer for structured near-critical populations in galactic phenomenology within the HγC framework. Earlier N-series work established band existence, band structure, and observational diagnostic language; O1 fixed the first explicitly galactic diagnostic morphology layer; O2 stabilized the first comparative morphology framework; O3 introduced the first comparative estimator layer; and O4 established the first narrower comparative calibration layer through selective informative contrasts. O5 takes the next justified step by asking whether the calibration-level judgments introduced in O4 remain coherent across multiple selective informative contrasts when…
