Abstract The M.E.M. Constitutional Corpus v1.0 is a collection of constitutional and governance-oriented documents developed to explore governance-first approaches to future socio-technical systems. The corpus derives from the Constitutional Decision Protocol (CDP), originally published in March 2026, and extends its principles into a broader constitutional framework for system design, governance, and revision. Rather than focusing on technological capability alone, the corpus investigates how constitutional constraints, epistemic limits, sovereignty principles, and governance structures can be established before system deployment. The corpus currently includes: • Core Axioms v1.0• Constitutional Corpus Overview and Document Relations v1.0• M.E.M.I.www Constitutional Architecture v1.0• M.E.M.I. School Companion Constitutional Architecture v1.0 Together these documents explore constitutional approaches to digital identity systems, citizen sovereignty, child-centered AI environments, recoverability, relational governance, and governance-constrained system development. The publication should be read alongside the original Constitutional Decision Protocol (CDP), which serves as the common constitutional ancestor of the corpus. This work is part of the broader M.E.M. Theory research project.
