AGI Constitutional Framework — Supplementary Note v1.8.1

This supplementary note consolidates the v1.8 structural additions to the AGI Constitutional Framework and prepares them for public release in a citation-ready format. The note develops the Mirror Principle from an ethical intuition into a governance-symmetry mechanism, then extends the framework through distributed block coordination, the Digital Constitutional Office (DCO), a constitutional calibration minimum for membership, the Grey Audit for compromised oversight, an agent maturity matrix, a de facto mandating collective for stateless AGI, the Goal-Origin Detection (GOD) module, the Consensus Asymmetry Principle, and Self-Psychology Protocol (SPP) v1.2. For publication clarity, the document also states its status explicitly: it is not positive law, soft law, or a technical standard, but a proto-constitutional governance design. A minimum operational specification of the Grey Audit is included to make the architecture easier to evaluate, cite, and formalize in future game-theoretic or multi-agent work.
