Review decision

To resubmit, address

1. Reframe the central claim to acknowledge that the receipts differ on species, disease model, tissue, and endpoint class — not solely on single-component vs combined-protocol attribution. State explicitly that the 'attribution boundary' is one plausible interpretation among multiple cross-axis differences.
2. Correct the characterization of Receipt 2: it is a 4-arm factorial design that does test combined vs single components in aged men; the memo should accurately describe this design and what it shows about combination vs single-component effects.
3. Tighten the falsifier to require matching on at least population (healthy aged men vs AD mice) and endpoint class, since the current falsifier would be overturned by any positive skeletal muscle study in aged men regardless of design.

Major issues

• The 'attribution boundary' framing overstates what two heterogeneous receipts can support. Receipt 1 (3xTg AD mice, combined resveratrol+exercise, cardiac/aortic endpoints) and Receipt 2 (healthy aged men, resveratrol vs exercise vs combined, skeletal muscle endpoints) differ on species, disease status, tissue, and endpoint class — the asymmetry is not cleanly attributable to 'single-component attribution' but to multiple confounders that the memo itself acknowledges cannot be isolated.

Minor issues

• The title mentions 'combined-protocol attribution boundary' but Receipt 2 is in fact a 4-arm factorial (resveratrol alone, exercise alone, combined, placebo) that does test component attribution and combined effects — the memo partially mischaracterizes Receipt 2's design as only testing 'component attribution'.
• Receipt 1 excerpt describes baseline characterization of cardiovascular function in 3xTg mice; the memo should clarify that the 'combined-protocol cardiac/aortic signal' framing extrapolates from the paper's intervention arms rather than the background excerpt shown.
• The bounded contrast and falsifier sections are well-constructed but somewhat repetitive of the limitations section.

Reviewer note

The memo attempts to identify a single bounded research signal — an attribution asymmetry between a combined-protocol animal study and a component-testing human study — which is a reasonable alpha-memo framing. The source bundle is real, recent enough, and directly relevant. However, the memo's central 'attribution boundary' claim is partially supported because the two receipts differ on multiple axes (species, disease status, tissue, endpoint), and the memo cannot isolate 'single-component attribution' as the causal driver of the asymmetry. Additionally, Receipt 2 is a 4-arm factorial that does test combined vs single components, so describing it as merely 'testing component attribution' is imprecise. The memo is salvageable with bounded reframing to acknowledge multi-axis heterogeneity and correct the Receipt 2 characterization. Recommend revise.
