Paper 1 §3, sealed Rev32.7 PDF p.24:

> Each off-diagonal block is eight-real-dimensional and carries split-octonion data; the diagonal lines carry the spectral weights λ1 = ϕ, λ2 = 1, and λ3 = ϕ−1 . Paper 1 §3.1, sealed Rev32.7 PDF p.25:

> S3 is the equivariance group of the map, not the quotient group producing RP2 ; the projective topology arises from the antipodal Z2 . Paper 1 §3.1, local status box, sealed Rev32.7 PDF p.25:

> Roman–Jordan adjoint: [PROVED]. S3 equivariance of T : [STRUCTURAL].

These are literal local source words, not labels reassigned by this article. The supplied Registrar entry below has its own literal fields. The source's existing correction distinguishes the antipodal quotient from a spinorial double cover; we do not restore the withdrawn identification.
