The manuscript's basic record-time framework is clear. Definition 2.1 distinguishes record-time stability from record-time unitarity and from a weaker record norm. The implication from unitarity to stability is correct: a tick-invariant positive form cannot assign changing norm to a physical eigenmode. Proposition 2.2 shows that the definitions are nonempty, and Lemma A.1 supplies a usable test excluding vertex moves for the displayed model patterns.
Section 3's bare-action obstruction is strong but conditional. Theorem 3.2 correctly shows that a physical mode multiplied by sqrt(2) under every record tick rules out a record norm, record-time stability and record-time unitarity. The mathematical obstruction follows once the claimed Bloch null vector is accepted. Appendix A.2 lists the polarization, but the actual null-vector check relies on Washburn [2, Prop. 6.16]. The same status applies to Theorem 3.4 at κ = 3/2. Theorem 3.5 is immediate from the fact that stability and unitarity depend on the solution space. The bare doubler continuum family in Theorem 5.4 is marked pending independent verification and is not established by a full certificate in this manuscript.
Section 4 is technically sound under its stated hypotheses. Theorem 4.1 is a correct linear-algebra lemma, and Theorem 4.3 follows by combining spatial periodicity, record-time stability and Theorem 4.1. Corollary 4.4 correctly includes the existence hypothesis for a physical off-zero mode. The manuscript does not overstate this result as a universal no-go theorem for all real weights.
Section 5's continuum criterion is mathematically coherent. Proposition 5.2 is correct and explicitly notes that continuum stability can be weaker and sometimes vacuous for roots staying away from the unit circle. The damped-model root identity is correct and usefully explains why fourth-order damping can be invisible in the continuum criterion while second-order damping is not. The proof of Theorem 5.3(i) contains a confirmed algebraic slip in Appendix A.3: the printed D l(4-l) <= 4 R g^2 should be replaced by a correct consequence such as D l(4-l) <= g^2 (R+1)^2, with constants adjusted. The qualitative claim remains plausible after this local correction.
Section 6 contains the main positive chain and the main proof gap. Theorem 6.1 imports the real-space derived weight and its symbol. Proposition 6.4's Laurent-extension logic is sound once the torus identities are granted. Theorem 6.5's decoupling argument is coherent once the imported kernel identity is granted: a nonzero off-zero limit killed by H_1 + i μ W would be killed by the weight and hence be a vertex-move polarization, contradicting the orthogonal physical component. However, this depends on Washburn [1, Thm. 5.6], not on a recomputation in this paper.
Proposition 6.7 is the central unresolved evidence gap. It lists four hard analytic ingredients for the zero-wave cubic bound: even second-order Fierz-Pauli reduction of the Regge symbol at complex covectors, second-order annihilation of long-wave strains by weight rows, an O(|k|^4) reduced Einstein estimate for physical weighted null vectors, and a nonvanishing Krein-form identity. These are asserted as exact facts with explanatory prose rather than proved in the manuscript or tied to precise external theorem statements with matching conventions. Theorem 6.8's contradiction proof is coherent after assuming them, and Theorem 6.9 follows after combining Theorems 6.5 and 6.8, but the headline continuum root-stability theorem is conditional from the submitted evidence.
Theorem 6.10 is also not independently established. The statement requires a complete analytic construction of a transverse fixing, injectivity, surjectivity, invertibility, holomorphy of the pairing F, uniform annulus bounds and constants independent of small b in the stated sectors. The submitted text gives only a high-level sketch and marks the theorem pending independent verification.
Section 7 is appropriately cautious. Theorem 7.1 proves indefiniteness once the two displayed rational cell-form evaluations are granted. Proposition 7.2 is a standard Jensen identity. The transfer-kernel reading and the zero-momentum one-loop remainder discussion are clearly labelled as further inference, not as established consequences of the root-stability theorem.
The manuscript's main required corrections are therefore narrow but consequential: prove or explicitly condition Proposition 6.7 and the theorems depending on it, supply or demote Theorem 6.10, sharpen the proved/imported/pending dependency map for load-bearing theorems and imported symbols, and fix the Appendix A.3 inequality. Objections demanding extra statements that branch existence is open, or that κ = 1 and (I1),(I2) are premises, are already answered by the manuscript and should not be treated as defects.
