Review decision

To resubmit, address

1. Rename or rephrase the title and one-sentence alpha to reflect the actual axis of contrast: Receipt 1 cannot separate components (combined protocol, animal-disease, cardiac/aortic) while Receipt 2 does separate components (aged men, skeletal/metabolic), so the boundary is an attribution-asymmetry across setting, not a clean translational boundary.
2. Clarify in the Synthesis that Receipt 2's exercise-alone fold-changes (PGC-1α, cytochrome c, etc.) are what Receipt 1's combined protocol cannot decompose, and that Receipt 2's resveratrol-alone arm showed no metabolic/inflammatory benefit — making the 'boundary' specifically about whether resveratrol adds anything beyond exercise.
3. Tighten the falsifier: 'A matched aged-men study where skeletal/metabolic endpoints improve under the same isolated intervention' is vague — specify which component (resveratrol alone) and against which comparator (exercise alone or placebo), since the existing Receipt 2 already partially serves as that falsifier for the resveratrol-alone arm.

Major issues

• Title/source alignment tension: the title promises an 'animal-disease-to-aged-men endpoint boundary,' framing a cross-setting contrast. Receipt 1 tests a combined resveratrol+exercise protocol in 3xTg mice, while Receipt 2 explicitly tests resveratrol alone vs. exercise alone vs. combination in aged men. Receipt 1 cannot isolate resveratrol's contribution and Receipt 2 cannot isolate exercise's contribution in the same way. The memo acknowledges this in 'Receipt-role check,' but the title and one-sentence alpha overstate the symmetry of the boundary by treating Receipt 1 as a clean 'combined-protocol signal' and Receipt 2 as a clean 'separates the components' study without naming the asymmetry explicitly in the headline.

Minor issues

• The 'Why this is surprising' section is thin — the surprise is really that Receipt 1 attributes benefit to a combined protocol while Receipt 2 attributes benefit to exercise alone, which is an attribution contrast, not a generic endpoint boundary.
• Excerpt for Receipt 2 is truncated mid-sentence ('3-hydrox'), and the cited fold-changes for exercise-alone arm are presented as if they characterize the full study; the placebo+exercise arm is the relevant comparator, not pooled effects.
• 'Single-component attribution if a receipt tests a combined protocol' appears in both limitations and scope language but is only relevant to Receipt 1; Receipt 2 actually does separate components, so the axis list slightly mischaracterizes Receipt 2.

Reviewer note

The memo identifies a real and interesting contrast between two well-chosen receipts: a 2019 combined resveratrol+exercise study in 3xTg Alzheimer's mice (cardiac/aortic endpoints) and a 2014 RCT in aged men (skeletal/metabolic endpoints) that separates resveratrol, exercise, and combination. Source grounding is strong — both DOIs match the cited claims, the excerpts are authentic, and Receipt 2's headline ('Exercise training, but not resveratrol') is accurately used. The research question is specific and the bounded contrast is explicit. The main weakness is title/source alignment: the title and one-sentence alpha imply a clean translational boundary, but Receipt 1 cannot isolate resveratrol's contribution while Receipt 2 can and did. The memo notes this in 'Receipt-role check' but does not surface it in the headline, leading to mild overclaim about the symmetry of the comparison. The falsifier is also slightly imprecise since Receipt 2 partially already serves as the resveratrol-alone aged-men test. Limitations and gaps are concrete and material. Synthesis is adequate but could be sharper about the attribution asymmetry. Revise recommended to reframe the title/alpha around the attribution asymmetry and tighten the falsifier.
