It remains an incomplete Mind engine because G4 horizontal relation, G5 whole convergence, G6 changed return, and G7 wider-local consequence are not implemented, and because the G3 numerical equation is candidate conformance rather than a canonical universal law. Four untracked concurrent prototypes are hash-recorded and explicitly excluded from authority."
