My concern is the same load-bearing gap: without the full statement and proof of the Bell-type result for relative frequencies, one cannot confirm that non-ideal frames truly make Born probabilities indefinite rather than merely noisy or mixed. No stronger internal inconsistency can be diagnosed from the abstract alone, so manufacturing a deeper objection would violate the good-faith rule. The recommended concrete test is simply to inspect and re-derive the missing theorem once the full text is available; until then the Reader’s verdict stands unchanged.","tokens_in":1981,"tokens_out":538,"duration_ms":5915,"concrete_test":"Obtain the full arXiv PDF and extract the precise statement of the Bell-type theorem for relative frequencies (including all assumptions on the reference-frame Hilbert space, the form of the relative-frequency observables, and the locality conditions).

Because only the abstract is available, neither the statement of that theorem, its assumptions (e.g., what counts as a non-ideal frame, how relative frequencies are formalized as operators or random variables, which locality/no-signaling conditions are imposed), nor the derivation that links frame non-ideality to irreducible frequency uncertainty can be checked. The optical pulsed-homodyne proposal is likewise uninspectable. Consequently the load-bearing step—from “measurements relative to finite-resource frames” to “Born probabilities are indefinite even in the infinite-run limit”—cannot be assessed for soundness or for hidden idealizations that would reintroduce a definite probability catalogue. This is an information gap, not a demonstrated flaw; the abstract’s argument may be correct once the full text is examined.","agreement_with_reader":"agree"},"referee_report":{"model":"grok-4.5","summary":"The manuscript argues that the standard assumption of a well-defined quantum state—a definite catalogue of Born probabilities—tacitly depends on measurements being performed relative to ideal, infinitely-resourceful reference frames. It claims that when measurements are instead made relative to non-ideal quantum reference frames, the Born probabilities themselves become indefinite: even in the limit of arbitrarily many runs, relative frequencies may remain uncertain. This uncertainty is asserted to be irreducible in a quantum-mechanical sense, certified by a Bell-type theorem for relative frequencies. A quantum-optical implementation based on pulsed homodyne detection is proposed. The authors motivate an extension of the quantum-state notion to finite-resource regimes and flag relevance at the quantum-theory/general-relativity interface, where resources in a bounded spacetime region are limited.","tokens_in":2220,"tokens_out":937,"duration_ms":17033,"significance":"If the Bell-type theorem for relative frequencies is correctly stated and proved, and if the ideal-frame premise is operationally well defined, the result would be a substantial foundational contribution: it would challenge the definiteness of the probability catalogue itself under resource constraints and supply a concrete, potentially falsifiable link between quantum reference frames and indefinite frequencies. The proposed pulsed-homodyne implementation would further raise the work above pure conceptual analysis. The abstract does not claim machine-checked proofs, released code, or parameter-free numerical predictions beyond the theorem itself; those strengths cannot yet be credited. The claimed QT–GR interface relevance is suggestive but secondary to the soundness of the theorem.","major_comments":[{"comment":"Only the abstract is available for this review.

They also sketch a pulsed-homodyne optical implementation and flag relevance at the quantum/GR interface where spacetime resources are bounded.\n\nWhat looks new, if it holds: treating the Born catalogue itself as relational and resource-dependent, and packaging that as a Bell-type no-go for relative frequencies rather than just another QRF decoherence or frame-uncertainty story. That is a clean conceptual target. The abstract is clear about the claim and does not dress it up as a data fit; it presents a theorem plus a proposed experiment. Credit for aiming at a load-bearing interpretive assumption and for naming an optical path.\n\nSoft spots are almost entirely information gaps, not demonstrated holes. We cannot check the theorem statement, what counts as a non-ideal frame, how relative frequencies are formalized, which locality/no-signaling conditions are used, or whether some idealization sneaks a definite catalogue back in. The pulsed-homodyne proposal is likewise uninspectable. The weakest assumption the reader flagged — that ideal frames are the tacit crutch for a definite Born catalogue — is exactly the premise that needs the full derivation. Circularity risk looks low from the abstract alone; free parameters and invented entities are not visible.\n\nWho it is for: people in quantum foundations, quantum reference frames, and quantum/GR interface work. A serious referee should see the full paper. I would not cite from the abstract, and I would not put it in reading group until the proof and protocol are readable. Send it to peer review if the full text arrives with a real theorem and a checkable optical scheme; desk-reject only if the full text fails to deliver those.
