Governance-First Experimental Framework for Replayable Recursive Propagation Measurements

This publication documents the construction of a governance-first experimental laboratory for replayable recursive propagation measurements. The work describes a replay-verifiable, provenance-aware, audit-honest infrastructure developed through Gates A through E of the Recursive Propagation research program. The paper does not claim validation of Recursive Propagation Theory, truth detection, hallucination detection, semantic-correctness measurement, reality measurement, illusion measurement, cognitive enhancement, artificial general intelligence, or consciousness. Its contribution is the construction of the measurement apparatus itself: sealed evidence, replay verification, provenance tracking, governance invariants, shadow-mode metric execution, and explicit non-claim discipline. The publication includes the full PDF paper and a supplementary source package containing the manuscript Markdown, appendices, figure assets, and figure manifest.
