(5)-(6) as the weakest foundational assumption. My concern sharpens this: not only is the postulate not derived from a deeper principle, but the explicit table of realisations does not demonstrably satisfy the postulate's coefficient restriction. The determinant of h3C, the first augmentation beyond the 4D SL(2,C) form, contains cross terms with coefficient ±2 in the real basis used for v9; the octonionic determinant used for E6 has the same structure. If the expansion confirms this, the paper's chain from 'generalised proper time' to exceptional symmetry is broken as written, although it could be repaired by relaxing the coefficient set or by finding a different normalisation. Because the mathematical facts about E6/E7 and the suggested SM correspondence are not disproved by this alone, the reader's CONDITIONAL verdict remains appropriate; the condition should explicitly include reconciling Eq. (5) with the determinant forms. I therefore leave the verdict unchanged while noting that the concern is more specific than 'the postulate is arbitrary': the paper's own examples appear not to instantiate it.","tokens_in":16217,"tokens_out":17163,"duration_ms":195175,"concrete_test":"Expand the standard 3x3 Hermitian determinant over C, det(h) = abc - a|u|^2 - b|w|^2 - c|z|^2 + 2Re(z uw), in the real coordinates z=x1+iy1, u=x2+iy2, w=x3+iy3, and list every monomial coefficient.

The determinant on h3C used for L3(v9)=1 has the standard expansion det(h) = abc - a|u|^2 - b|w|^2 - c|z|^2 + 2Re(z uw), with the 2Re cross term. In the real basis in which v9 has 9 real components, this cross term expands into monomials with coefficients ±2, not ±1. The same coefficient appears in the h3O determinant used for the E6 entry. Hence L3(v9)=det(v9)=1 and the analogous octonionic norm are not instances of Eq.

Section 3 then concedes that the neutrino and u-quark states do not have the correct Lorentz spinor structures, that the full electroweak SU(2)L symmetry is absent, and that the E8 completion is conjectural.

The author argues that this generalised proper time leads naturally to octonionic structures and to the exceptional Lie groups E6 and E7, with a predicted E8 stage (Eq. 9). Upon symmetry breaking through the extraction of a 4-dimensional spacetime background, the resulting fragmented components are claimed to reproduce a series of Standard Model features: Dirac spinors, SU(3)_c singlets and triplets, and U(1)_Q fractional charges, as summarised in Table 3.

However, the load-bearing steps are not established in the manuscript itself: the symmetry-breaking table is inherited from an unpublished preprint, and the claimed realisations of the generalised proper-time norm in Table 2 appear to conflict with the coefficient restriction in Eq.

The paper might be more suitable as a programmatic or review-style contribution than as a research article."},"author_rebuttal":null,"desk_editor":{"model":"deepseek-v4-flash","letter":"Two things to know before you read it. First, this is not a new result: it is a summary of the author's own preprints, and Table 3, the Standard-Model correspondence, is explicitly inherited from [36]. What is new is only the 'generalised proper time' framing, which is a nice conceptual hook but is not developed beyond citation. Second, the central construction has a real internal problem. Equation (5) defines the generalised proper time as a homogeneous polynomial with all coefficients in {-1,0,1}. But the explicit realisations in Table 2 are determinants of 3x3 Hermitian matrices over C and O. Those determinants contain cross terms of the form 2Re(zuw), which expand into monomials with coefficients ±2 over the real components of v9 and v27. So L3(v9)=1 and L3(v27)=1 are not instances of Eq. (5) as stated. The paper never derives these determinant forms from the postulate; it cites earlier preprints. That is a load-bearing flaw, because the whole route from generalised proper time to SL(3,C), E6, and E7 passes through those tables.\n\nThe paper is not without merit. It is clearly written, and it honestly flags the gaps: no full electroweak SU(2)L, incomplete Lorentz spinor structure for neutrino and u-quark states, and an admittedly conjectural E8 completion. The background on octonions and exceptional groups is standard and accurate. As a compact statement of this research program, it is serviceable.\n\nBut the soft spots are substantial. The derivation of Table 3 is not in the paper; it is deferred to an unpublished preprint. The matching to the Standard Model is partial by the author's own admission. The self-citations are not themselves a problem when results are reproducible, but here the cited preprints are not externally verified and at least one appears to contain the same coefficient issue. The internal inconsistency with Eq. (5) attacks the foundational postulate, not just a peripheral calculation.\n\nBottom line: I would not send this to a referee. The paper is not ready: the central mathematical claim is not established, and the paper is not a new contribution beyond the earlier preprints. If the author can repair Eq. (5) or show that the determinant forms can be rescaled to satisfy the coefficient condition, it would be worth another look. Until then, it is a coherent but flawed summary.","headline":"A clear summary of the author's own octonionic proper-time program, but the central foundation is internally inconsistent: the determinant forms in Table 2 have coefficients ±2, contradicting the coefficient condition of Eq.
