C.30.STRAT:1 - Problem frame

Architecture and engineering sources use compact labels because they work in local practice. Neural-network prose says block, expert, cache, or router; control architecture says layer; organizations say level or tier; documentation says section, stack, or view; scale prose says level, resolution, or coarse-graining step.

These words are good recognition cues but poor stand-alone kinds. The same label can point to a selected structure, module relation, control relation, transformation-flow element, characteristic or scale, publication grouping, state, evidence claim, decision, or nothing beyond ordinary prose.

The repair question is simple: what does the label name in this sentence, what use does the recovered claim support, and which existing pattern supplies the needed definition, constraint, or test?
