Review decision

To resubmit, address

1. Soften the one-sentence alpha and 'Why this is surprising' to reflect that Receipt 2 documents training-induced K⁺-transport protein isoform shifts across a sprint-interval program with CWI as an arm, not a demonstrated CWI-caused fiber-type-specific effect; the CWI-specific contribution cannot be cleanly separated from the training stimulus on the available evidence.
2. Add a brief note acknowledging the truncated excerpt for Receipt 2 and clarify that the fiber-type-specific α1/β1/β3/FXYD1 pattern is attributable to the training stimulus, with CWI's independent contribution not clearly established in the bundle.
3. Consider tightening the boundary claim: the two receipts differ on so many axes (heat vs sprint-interval, 5 days vs 6 weeks, session-RPE vs biopsy) that the 'modality boundary' is a cross-context heterogeneity observation, not a falsifiable moderator claim; the current framing slightly overstates the integrative power of the two-study pair.

Minor issues

• The framing in the 'Why this is surprising' section and one-sentence alpha overstates Receipt 2: the 2018 study reports training-induced Na⁺,K⁺-ATPase isoform shifts but the excerpt and abstract as written do not establish that CWI *caused* the fiber-type-specific pattern, only that training did. The memo partially walks this back in Caveats but the headline 'shifts Na⁺,K⁺-ATPase isoform abundance in a fiber-type-specific way' reads as a CWI-specific effect when the source bundle does not cleanly support that attribution.
• Receipt 2's excerpt is truncated at 'α 2 and α 3 abundan', making it hard to verify whether the CWI vs CON contrast on α2/α3 was reported; the memo acknowledges this implicitly but the title and abstract still imply a definitive fiber-type-specific CWI signal.

Reviewer note

The memo is a well-structured, source-bounded alpha-memo that correctly anchors two genuine receipts in the CWI literature (2020 heat-based training-load paper; 2018 sprint-interval K⁺-transport paper). Source grounding is strong: both citations resolve to the correct DOIs and the excerpts match the claims. Limitations and gaps are exemplary — the caveats section honestly itemizes the multiple axes on which the two studies differ and proposes a concrete falsifier. The main weakness is mild overclaim in the headline framing. The 2018 paper's bundle shows training-induced Na⁺,K⁺-ATPase isoform shifts; it does not clearly establish that CWI *caused* the fiber-type-specific pattern, only that CWI was an arm. The memo partially catches this in Caveats but the one-sentence alpha and 'Why this is surprising' still present the CWI-fiber-type effect as established. This is a bounded, fixable wording issue, not a structural defect. Given strong source grounding, honest limitations, and a specific falsifier, the manuscript is closer to accept than reject, but the attribution problem in Receipt 2 warrants a bounded revision before acceptance.
