E.17.AUD:8 - Rationale
PublicationUnit Stability Discipline is worth stating explicitly because local lexical-head repair and whole-unit primary-subject stabilization are both already real problem situations, but authors and reviewers still need one stabilization check that says when the case is local, when it is whole-unit, when it is already bounded comparison, and when it has left the publication-unit stability family entirely.
The pattern stays intentionally narrow. It does not turn every publication-unit problem into publication design or downstream decision, gate, work, or reliance work. Its job is to keep one publication unit honest enough that readers can still tell what it is mainly about, which carried publication move it makes, and which downstream U.Work, work planning, decision, gate, or reliance claim remains outside.
