I depart in two respects. First, the paper does derive the couplings (5.29) from the Jacobi identities of (5.28) itself, so the couplings are not purely assumed; what is genuinely deferred (b633) is the consistency of those couplings with the matter action through (5.21)=(5.19), which is the holomorphic analogue of the Appendix D solve that established the antiholomorphic claim (b246). Second, the reader lists the (5.43) anticommutator as verified only on the positive gravitino field (b391), but the accompanying footnote 49 explicitly states all eight other matter fields were checked, so I do not weight that item. The decision to keep the CONDITIONAL verdict rests on the (5.21) gap: it is specific, named, and central to the novelty claim, and the concrete test I propose would settle whether (5.28) with couplings (5.29) genuinely generates the action of the N=8 ¯w_{1+∞} symmetry. I also credit the paper's independent support where it exists: the antiholomorphic sector reproduces the known [32] algebra and its coupling structure for s1 ≥ s2, and the residual s1 < s2 gap (b245, b627) is honestly flagged. Neither gap is an internal inconsistency; both are incompletenesses, and the holomorphic one directly threatens the paper's central new claim.","tokens_in":99299,"tokens_out":8948,"duration_ms":52602,"concrete_test":"Run the section-4-style check in the holomorphic sector: for each of the 45 (anti)commutator pairs of (5.28)/(E.5), act the two modes successively on each of the nine matter-field types using the differential realization (5.13)/(5.14), form the graded difference (5.19), and demand equality with the single-mode (anti)commutator of the combined current with the ((q-1)m-(p-1)n) coefficient.

In the antiholomorphic sector, the claim that 'the charges generate the action of the N=8 w_{1+∞} supersymmetry' (b246) is established by solving the 95-relation consistency system (4.3)=(4.1) in Appendix D, yielding λ = κ (4.14). The analogous holomorphic consistency relation is (5.21)=(5.19), but the paper applies it to exactly one pair, the two gravitino currents acting on a scalar (5.23)-(5.26), then states 'it is straightforward to continue', supplies (5.28) as obtained from the Thielemans package, solves the algebra's own Jacobi identities to obtain (5.29), and defers the (5.21) check itself to future work (b633). There is a genuine asymmetry: (5.29) establishes that (5.28) is a closed algebraic structure with couplings in terms of eight constants, but it does not establish that those constants are compatible with the realization (5.13) on matter for all 45 relations. In the antiholomorphic sector, that compatibility is exactly what forced λ = κ and is the content of 'generate the action of the symmetry'. If (5.21) is not identically satisfied for the remaining pairs, particularly the mixed-helicity triples involving the positive-helicity holomorphic currents of (5.54) with the scalar and graviphotino fields, the couplings (5.29) would require revision and (5.28) would not be a symmetry of the matter action; the BMS subalgebra identification (6.60) built from (5.28) would then also be affected. The s1 < s2 gap in the antiholomorphic sector (b245, b627) is related but separate: the λ = κ conclusion was solved only for s1 ≥ s2, and the paper itself expects further constraints.

From the antiholomorphic light transform it constructs OPEs and mode (anti)commutators of the N=8 w_{1+∞} currents with all matter fields, derives the current-current-matter consistency system (4.1)-(4.3), and reproduces the known [32] celestial soft symmetry algebra, with the λ couplings determined in terms of eight independent κ couplings (4.14). The paper then repeats the construction for the holomorphic light transform, obtaining the barred-current OPEs and (anti)commutators (5.13), a consistency system (5.21), and a new holomorphic-sector algebra (5.28)/(E.5) whose couplings are solved from its Jacobi identities (5.29). It identifies the N=8 extended BMS algebra as a subalgebra in both sectors, including the mixed supercurrent anticommutator (5.43), and finally rewrites the construction in the soft-current and shadow-transform bases, identifying the Virasoro generators, supercurrents, and supertranslation generator (6.60).

The paper deserves credit for reproducing the known [32] algebra as an internal consistency check rather than announcing it as new, for careful weight and SU(8) bookkeeping, and for making the 45 OPEs and 45 (anti)commutators explicit in the appendices. However, the central new claim—that (5.28) is a symmetry of the matter realization—is currently supported only by a one-example check of (5.21) and by the algebra's own Jacobi closure; this asymmetry with the antiholomorphic sector is the main correctness risk.

This does not establish that (5.28) is compatible with the matter realization (5.13) for all 45 relations: in the antiholomorphic sector, exactly that compatibility forced λ=κ and underlies the claim in b246 that the charges generate the symmetry. The paper itself lists the full check as an open problem (b633).

That is real evidence, and the paper deserves credit for doing it rather than relabeling it new.\n\nThe soft spot is exactly what the stress-test flags, and it lands on reading. In the antiholomorphic sector, the claim (b246) that the charges generate the N=8 w_{1+∞} action is established by solving the full 95-relation system, and that is what forces λ=κ.
