I therefore agree with the REJECT verdict: the central claim is unsupported as written.

The effective sources (43) and the nonlinear symmetries (70)-(73) are chosen so that the Einstein equations (46)/(73) are satisfied by construction, which makes the gravitational part a prescription rather than a derivation of a coupled matter-gravity solution.

What is new: a nonmetric EDM system in f(Q) variables, eqs. (44)-(46), with a total source that folds Dirac and Maxwell nonmetric distortions. I checked the cited [22] and [17]-[19]; they don't have this coupled program. The metric ansatz and the algebraic formulas (64)-(66) are internally consistent and follow the author's established pattern from refs. [20,21]. The explicit KdS, wormhole, and toroid line elements in Sec. 4 are generated in the usual way, and as metric constructions they probably check out.\n\nThe soft spot is load-bearing. The headline claim is that those metrics are solutions of the full nonmetric EDM system. For that you need, for each metric, a spinor Psi and a gauge potential A satisfying (44) and (45). None is exhibited, and Sec. 3.2.3 says the explicit QF and ej computations are not the purpose of the work and are deferred. The mass shift (75) is defined through an arbitrary 4x4 matrix B; with B unconstrained, \"anisotropic mass polarization\" is a bookkeeping device, not a prediction. The same happens for effective sources: matter content is absorbed into generating functions, so the equations close by construction. This is a parametric construction of metrics with prescribed effective sources, not a demonstration of EDM solutions.\n\nI also flag the unusual passage in Sec. 1.2: the paper says the number of self-citations is increased and references to other authors are included only if important. That is a bad look, but I don't think it changes the technical assessment. It does mean the novelty claim needs a careful external check.\n\nThe Perelman thermodynamics section is speculative; the variables depend on effective cosmological constants that are themselves free functions, so they don't yet encode actual fermion or photon data.\n\nWho gains: people working on exact off-diagonal solutions in modified gravity may find the algebraic machinery useful. As a paper about nonmetric EDM solutions, it fails as stated; but the failure is reparable.

The proposed cure is to write the nonmetric connection as the metric-compatible connection plus a distortion, working in anholonomic (2+2) dyadic variables, where the nonmetric distortion becomes an extra spin connection and an effective mass term. On that basis the paper formulates a nonmetric Einstein-Dirac-Maxwell (EDM) system, equations (44)--(46) with sources (43), and claims that nontrivial nonmetricity fields $Q$ produce locally anisotropic modifications of fermion mass and act as effective sources in the Maxwell equations. It then generates quasi-stationary off-diagonal solutions describing black ellipsoids, wormholes, and black toroids, with thermodynamics computed from W-entropy functionals rather than standard black-hole surface entropy.

In that form the f($Q$) EDM equations decouple into a two-dimensional Poisson equation for the conformal factor and integral equations for the metric and N-connection coefficients, solved by generating functions and effective cosmological constants.
