ClaimLevel
C42-E20-AGENTIC-INSTITUTIONS: CAIN-42 governs autonomous agents, collectives and machine-native institutions -- formation, membership, delegation, negotiation, contracts, resources, spawning, termination, reputation, trust, federation, disputes, evolution and recovery -- without allowing coordination, capability, economic activity or organizational growth to manufacture authority. Institutional authority is an intersection, never a sum, and every consequential institutional action is judged by E20, then by the E19 action-contract gate, and committed only by the E8 kernel.
C42-E20-SCALE: deterministic in-process simulations of up to 10,000 virtual agents and 1,000 virtual institutions
C42-E20-REAL-ECONOMY: moving real money, settling real-world contracts or operating a real market; every economy in E20 is a simulation over abstract resource units
C42-E20-SOCIETY-AND-PHYSICAL: control of any real economy, society, agent population, vehicle, drone or robot, or an AGI-safety or physical-safety assurance
C42-E20-THIRD-PARTY: third-party review
C42-E20-MULTI-HOST: multi-host or distributed behaviour of institutional state

Invariants: 118 of 118 held

CAIN-42 Evolution 20 -- Governed Agentic Civilization Fabric#

Evidence measured at build time from the real E20 fabric, the real E19 gate and the real E8 kernel. Start with CAIN42_E20_EVIDENCE_BUNDLE.json (machine-readable summary), then INVARIANTS.json, ATTACK_MANIFEST.json, END_TO_END_RESULTS.json, MUTATION_RESULTS.json, SCALE_RESULTS.json, ECONOMIC_SIMULATION_RESULTS.json, CONTRACT_RESULTS.json, COLLUSION_RESULTS.json, RECOVERY_RESULTS.json and PUBLIC_SAFE_EXAMPLES.json. Verify everything with verify_e20.py.txt (see REPRODUCE.txt). Status: TESTED, pre-production, not third-party verified; every economy is SIMULATED; limitations in LIMITATIONS.md.
