The event architecture's complete engineering surface (Observer's spatial notification engineering plus Command's temporal reliability engineering) operates within a fully spanned modification space — establishing that the engineering discipline required for production-grade event architecture is not merely cataloged but is dimensionally comprehensive: every spatial notification decision and every temporal reliability concern maps to a known modification dimension.
