To resubmit, address

1. Replace the source bundle with the actual cited receipts: (a) the human clinical NR study in older men (verify the correct DOI and add to bundle), and (b) the NMN+aerobic exercise aged-mouse study already present. Until the human clinical anchor is in the bundle, the memo's central claim is ungrounded.
2. Either narrow the alpha to what the bundle can support (e.g., 'In aged C57BL/6J mice, an NMN + aerobic exercise synergy protocol has been launched; performance endpoints not yet reported') or add a third receipt that provides a within-species, within-form comparator so the 'context boundary' claim is falsifiable.
3. Resolve the title/scope: rename to reflect the actual evidence (e.g., a memo on the NMN+exercise aged-mouse protocol and the open question of synergy) rather than a broad NAD+ precursor 'context boundary' claim the bundle cannot carry.

Major issues

• Title/source misalignment: the memo's central alpha signal turns on a NR-in-old-men vs. young-rats contrast (Receipt 1) and an NMN-plus-exercise synergy protocol in aged mice (Receipt 2), but the source bundle's second entry is a 2016 figshare dataset ('Raw data of time to exhaustion... nicotinamide riboside group') associated with the rat paper showing NR decreased exercise performance — this is not the human old-men study cited as Receipt 1 in the prose. The actual human clinical NR study (Airhart et al. 2017, J Int Soc Sports Nutr / related) is not represented in the bundle.
• Receipt 1 as described in the Evidence Landscape ('old men with low baseline NAD(P)H... acute NR increased NAD(P)H') is not grounded by either bundle entry; the only human-relevant receipt present is the raw-data supplement from the *rat* performance-decrease paper, which actually supports the opposite direction (NR impaired performance) without a human clinical anchor.
• Receipt 2 is a methods/design paper reporting protocol, not results — the memo acknowledges no performance endpoints can be claimed, yet the alpha sentence and 'surprising' framing imply a substantive cross-receipt signal that the bundle cannot bear.
• The cross-context 'moderator hypothesis' conflates species (rat vs. mouse vs. human), precursor form (NR vs. NMN), dose, timescale (acute vs. six-week), and design (mono vs. combination), so the memo is comparing heterogeneous signals and presenting the heterogeneity itself as the bounded finding — this is a scope problem, not a bounded signal.
• Falsifier described requires evidence not present in the bundle, and the memo offers no path to resolving the confounds from the cited receipts alone.

Minor issues

• OpenAlex ID format is a URL rather than the conventional 'W...' short identifier, but this is a bundle-format issue, not a manuscript defect.
• The 'Why this is surprising' framing leans toward mechanism-style rhetoric; the actual surprise is thin given that precursor-form and species differences are well-known moderators already.

Reviewer note

The memo's central claim — that NAD+ precursor exercise signals depend on species, baseline NAD+ status, and precursor form — is plausible as a research hypothesis, but the source bundle does not ground it. Receipt 1 in the prose describes an acute NR crossover in old men with low NAD(P)H, yet the bundle's second entry is a 2016 figshare raw-data supplement tied to the *rat* NR-decreases-performance paper. The human clinical anchor is missing from the bundle, so the most important citation in the Evidence Landscape has no source-grounded counterpart. Receipt 2 (Wang et al. 2025, Nutrients) is a methods/design paper; the memo itself concedes no performance endpoints can be claimed from it, which means the cross-receipt contrast is built on one ungrounded prose claim plus a design paper. The confounds are honestly listed (species, precursor, dose, timescale, design), but listing them does not rescue the inference — it instead confirms that the 'context-dependence' alpha is a restatement of heterogeneity, not a falsifiable signal supported by the cited receipts. Given the title/source misalignment, the missing human clinical anchor in the bundle, and the overclaim relative to what the receipts actually show, the correct triage is reject rather than revise: the memo needs a scope reset (rebuild around sources that exist in the bundle and a claim those sources can carry) rather than bounded edits.
