## Statement

(none)

## Caution

No unconditional vacuum selection follows from the old elimination title or from a conditional replacement theorem.

Appendix E, §3, Remark 2: conditional role of DET-7, PDF p.171: "DET-7 enters this appendix as a structural postulate, not a derived necessity; the result is therefore a conditional selector theorem."
