To resubmit, address

1. Replace or supplement Receipt 2 with the parent article DOI (10.3389/fphys.2018.00704) so the main phenotypic claim is grounded in the primary publication rather than its supplementary data file.
2. Reframe the 'protocol mismatch' title to accurately reflect the intervention contrast (NR supplementation vs. NAMPT overexpression; human acute vs. mouse chronic training) or narrow the claim so the title and receipts align.
3. Tone down the 'surprising / framing does not cleanly survive' language to acknowledge that the two studies test different interventions in different species and that the conditional vs. unconditional distinction remains tentative and confounded.

Major issues

• Receipt 2 in the source bundle is a supplementary data file (DOI ending .s001), not the primary article. The primary article would be the parent Front Physiol paper (10.3389/fphys.2018.00704). Citing a data supplement as the receipt for the main phenotypic claim (NamptTg mice show higher endurance and VO2 max) is misleading; the memo should cite the parent article or both.

Minor issues

• The title says 'nicotinamide exercise performance protocol mismatch,' but Receipt 1 uses nicotinamide riboside (NR) while Receipt 2 uses NAMPT overexpression — these are not the same intervention nor the same protocol axis. The 'protocol mismatch' framing slightly obscures that this is also an intervention/axis mismatch (supplement precursor vs. transgenic enzyme overexpression, human acute vs. mouse chronic training).
• The 'surprising' framing implies Receipt 2 overturns Receipt 1, but the two are not directly comparable: human acute NR in age-stratified men vs. transgenic mice with chronic training. The conditional-vs-unconditional framing is plausible but the contrast should be stated more cautiously.
• Receipt 2's excerpt does not explicitly state 'higher endurance and VO2 max' as a confirmed result — the opening sentence is descriptive. The memo should note this is from the parent paper's framing and verify the claim rather than presenting it as directly excerpted.

Reviewer note

The memo makes a clear, bounded comparative signal: Receipt 1 supports an age/baseline-conditional ergogenic effect of NR in humans, while Receipt 2 suggests NAMPT overexpression in young, healthy mice can elevate endurance and VO2 max with training. Synthesis is coherent and the falsifier is well-stated. However, Receipt 2 as listed is a supplementary data file, not the primary article, which weakens source grounding for the main phenotypic claim. The title's 'protocol mismatch' framing slightly understates that the receipts also differ in intervention type (supplement precursor vs. transgenic overexpression) and species, making the conditional-vs-unconditional contrast more tentative than the memo implies. Bounded edits — citing the parent article for Receipt 2 and tightening the framing — would make this accept-quality.
