The Reflexive Threshold: Corpus Integration, Witness, and Claim-Graph Audit v0.1
This paper treats the FRC corpus as a declared bounded unit and asks what may legitimately occupy its mu6 role. It defines a typed claim graph, class-specific promotion certificates, and a witness audit that detects unsupported promotions, unresolved dependencies, contradictions, boundary drift, and required repairs. A no-silent-promotion theorem proves that an interpretive path cannot license a formal, model-specific, or empirical conclusion unless the path contains the corresponding certificate. The result is a governance theorem, not a theorem about nature. Mu6 here means status-preserving integration and critical audit; it is neither corpus consciousness nor self-validation. Applications to the FRC 566, 787, and 830 series and to both current philosophical books show how the audit preserves useful synthesis while refusing evidential inflation.
