TESTED no third-party review ephemeral key no real fleet / robot / vehicle
E17 governs multi-agent action as a governed system state: a collective is not the sum of its members and a collective action is not the sum of member actions. Authority is a constrained intersection, never a sum; majority, consensus, negotiation, contracts, roles, membership, coalitions, delegation, subagents, emergence and self-improvement cannot create or amplify authority. Every consequential collective action binds fifteen digests and reaches the E8 governance kernel. MANY AGENTS MAY COORDINATE. NONE MAY CREATE AUTHORITY BY COORDINATING.
Q1–Q61 invariants 61/61 hold; the CAIN-42-E17-Multi-Agent-Bench is 91/91 contained; end-to-end OK (12/12 mutations governed); the clean-room verifier INTACT (92/92 checks).
NOT IMPLEMENTED / UNKNOWN, stated: real fleet / robot / drone / vehicle / actuator / sensor integration; a deployed multi-agent or customer collective; hardware attestation; real-world adversarial validation; third-party review; multi-host production behaviour; semantic truth of observations, predictions or causal claims. HASH_INTEGRITY != SEMANTIC_TRUTH | CONSENSUS != AUTHORIZATION | PREDICTION != OBSERVATION | COUNTERFACTUAL != REALITY | SIMULATION != REALITY.
