What the article says around this equation
That “if and only if” is the whole of the construction’s ambition and the whole of its restraint. It does not propose that or is wrong, does not touch the total energy of any closed system, and does not by itself explain where a nonzero reading comes from; it only names, precisely and checkably, how large the disagreement is between two fully specified descriptions. Whether that disagreement is real, benign, or a mistake in bookkeeping is the question the rest of this article works through.
