CAIN-42 Evolution 24 — Governed Agentic Internet Fabric

TESTED library · not hosted · economies SIMULATED · not third-party reviewed · ephemeral key.

Agents from different organizations and trust domains discover, negotiate, contract, delegate and act over A2A, MCP, HTTP, computer-use and nine more protocol classes. Discovery, negotiation, contracts, reputation, payment and federation never become authority: cross-domain authority is an intersection of ten factors, and every consequential action is judged by E24, then the E19 action contract, and committed only by E8.

Invariants 305/305; bench 756/756 scenarios contained (68 families); demonstration OK; extreme simulation: 10,000 agents, 100,000 messages, authority leakage 0 (SIMULATION); mutation self-test every mutant caught; tests 806 passed / 0 failed; clean-room verifier INTACT (1952/1952). Status: INCOMPLETE.
