A.6.3.CR:5.2.c - Boundary to controlled coarsening

Source slice. Vendor bulletin VB-7 requires rollback when pressure drift exceeds 2.5%, and it keeps two equipment-specific exceptions in the pinned annex.

Published coarsened slice. Pressure drift above 2.5% is a warning condition in the bulletin. Check the pinned bulletin and annex before treating the note as rollback guidance.

This does not remain ordinary ConservativeRetextualization. The coarsened slice drops equipment-specific exceptions and remains only an orientation warning: it is not an executable rollback command. It can stay honest only through narrower admissible use, non-admissible downstream use, and source-bearing return to the source-bearing bulletin. Once that narrower-use boundary becomes primary, the case leaves ordinary same-entity rewrite and must use A.6.3.CSC Controlled Semantic Coarsening rather than being treated as a harmless summary.
