In common English, a breach is the damage left be an attack (often a hole in the case of penetrating ordinance, as in "a breach in the hull of a ship"). Breach definitely does not, in common English, refer to a theoretical, unexploited hole in one's defenses. I would be interested if you could point out any instance in literature or professional writing where it is used that way. Also common English is notoriously unimportant when arguing over legal definitions, so this is all beside the point.
