## Statement

The missing 16-scalar sector is identified as the identity-anchored Jordan complement 42 ⊖ 26 inside the maximal-supergravity coset.

## Caution

The complement identification is not a consistent truncation to the Jordan-visible sector and does not establish the unprinted named-projector certificate.

## Primary source

Paper 4, §4.2, Ghost-free reading: identity-anchored complement, PDF p.73: "the missing 16 is the identity-anchored Jordan complement 42 ⊖ 26 inside the maximal-SUGRA coset, pinned on the certified E7(7) substrate."
