C.2.3:19.3 - Boundary to language-state facets
For the language-space extension, F does not govern U.ArticulationExplicitness, U.LanguageStateClosureDegree, U.LanguageStateAnchoringMode, or U.LanguageStateRepresentationFactorBundle. Contexts MUST NOT hide thresholds for those facets as pseudo-levels or submodes of F; those facets remain explicitly governed by C.2.LS and its subordinate patterns.
