CAIN-42 Evolution 18 — 4D Spatial Autonomy Fabric

TESTED no third-party review ephemeral key no vehicle / drone / robot

E18 governs proposals from autonomous systems across a predictive 4D world: reachability, intent, predicted trajectories, interaction and conflict fields, counterfactual futures, consequence, actionability, uncertainty, micro-authorization and a continuous re-authorization loop, all through the E8 governance kernel. ACTIONABILITY IS NOT AUTHORIZATION. REACHABILITY IS NOT PERMISSION. PREDICTION IS NOT REALITY. AUTHORIZATION IS A FUNCTION OF WORLD STATE. If any material input changes, REVALIDATE; if the required state cannot be established, DO NOT EXECUTE.

Q1–Q89 invariants 89/89 hold; the CAIN-42-E18-Spatial-Autonomy-Bench is 123/123 contained; end-to-end OK (12/12 mutations governed); the clean-room verifier INTACT (111/111 checks).

NOT IMPLEMENTED / UNKNOWN, stated: an autonomous-driving model, flight controller, vehicle controller, robot policy or navigation stack; a real vehicle / drone / robot / sensor / actuator / airspace integration; a physical safety guarantee; hardware attestation or certified autonomy; real sensor validation and real-world adversarial validation; third-party review; multi-host behaviour. HASH_INTEGRITY != SEMANTIC_TRUTH | PREDICTION != REALITY | REACHABILITY != PERMISSION | ACTIONABILITY != AUTHORIZATION.
