 * any constitution, and not amendable by an entity. This namespace is a
 * declared stub per the PRD: the rules are named and versioned here so
 * models and templates can reference them; the operational hooks bind at
 * Phase 4 (APAP server), not in this phase.

 * provenance:
 *   source: universal-constitution v2-minimal-core-study.md §3 (Registry Rules v1)
