Reviewer note

This is an elite-tier research synthesis that exemplifies the v2 publishing-grade path. The manuscript demonstrates exceptional rigour in its separation of evidence tiers and directness, ensuring that mechanistic plausibility is never conflated with clinical efficacy. Key strengths include: 1. **Explicit Traceability**: The use of a Quantitative Evidence Index (Findings Map) and a detailed Source Classification Map allows for immediate auditing of claims against the 33-source corpus. Numerics (p-values, HRs) are tied directly to specific bundle tokens. 2. **Cross-Domain Integration**: The 'Cross-Domain Synthesis' section is a highlight, explicitly identifying and analyzing tensions (e.g., the conflict between BMI signals in Hu 2021 vs. Kim 2024) rather than smoothing them over. This transforms the paper from a summary into a true synthesis. 3. **Rigorous Hedging**: The author consistently applies a 'bounded conclusion' framework. The distinction between 'direct' and 'indirect' evidence is maintained throughout, and the manuscript correctly identifies that while metformin is a glucose-lowering backbone, its repurposing for longevity or frailty is not yet supported by the direct human evidence in the corpus. 4. **Methodological Transparency**: The PRISMA-ScR approach, combined with a deterministic protocol and AI-disclosure, provides a high level of reproducibility. 5. **Substantive Limitations**: The limitations are not generic; they specifically address evidence-role imbalance and endpoint heterogeneity, which materially constrain the conclusions. The manuscript successfully navigates the complex landscape of geroscience by being honest about where the evidence is sparse or mixed, which is the correct scholarly verdict for this topic.
