Review decision

To resubmit, address

1. Add explicit falsifier language in the alpha sentence: 'preliminary, mechanistically credible but not established.'
2. Clarify that the context-dependence hypothesis is mechanistically motivated and supported by exactly two primary studies, not a settled consensus.
3. Consider noting species-specific plausibility boundary (rat decrement vs human acute increment) as a limitation distinct from age/baseline.
4. Optionally expand the caveat about confounded axes (species, dose, duration, acute vs chronic) to a short dedicated limitations sentence.

Minor issues

• The title says 'context boundary' but the body argues only an age/deficiency moderator hypothesis; could be tightened to 'age/baseline context dependence' or similar.
• Receipt 2 description says '12 young vs 12 old men' but the original was acute NR in young and old with acute exercise; ensure phrasing does not overstate 'improved physical performance' without noting acute exercise context.
• The 'surprising' framing implicitly assumes Receipt 1 generated broad NAD+ ergogenic expectations, but Receipt 1 actually showed a decrement, not a null; the surprise axis could be stated more precisely.

Reviewer note

Bounded alpha-memo with two cleanly aligned primary receipts (Kourtzidis 2016; Aguiar 2020 acute NR exercise study). The context-dependence framing is honestly presented as tentative and explicitly hedged ('may split', 'suggests', 'rather than'). Source grounding is strong: both cited_as DOIs map to bundle entries with matching titles, years, and design details (n=18 Wistar rats, 300 mg/kg/day 21-day; 12 young vs 12 old men, acute cross-over). Limitations are specific (confounded species/dose/duration/acute-vs-chronic axes) and the falsifier clause is concrete. Recommend revise (not accept) because the central signal rests on n=2 heterogeneous primary studies and the manuscript, though appropriately hedged, would benefit from (a) a single explicit 'preliminary, mechanistically credible' qualifier in the alpha sentence, and (b) a slightly more precise framing of what 'context boundary' means here (age/baseline NAD+ status in humans, with the rat decrement as a separate species/schedule comparator). No major issues; no overclaim; no injection attempts detected.
