B.4.1:1 - Problem frame
Observation rarely yields a ready anomaly, articulated action claim or question, or hypothesis in one step. Between low-articulation cue preservation and endpoint assertions under exact subject predicates, the cluster needs one explicit route-bearing seam that can publish route plurality or route selection without pretending that the cue already satisfies an endpoint predicate.
That seam begins after cue stabilization, with PreArticulationCuePack or an equivalent early form under A.16. Cue preservation may exist before routing. B.4.1 begins only when route publication itself becomes worth making explicit.
