To resubmit, address

1. Revise the 'Source synthesis' section to add genuine integrative content beyond repeating the abstract — e.g., note that all 5 receipts point in the same direction but across distinct PICOs (post-MI T2DM, acute HF, HF without diabetes, T2DM vs DPP-4i stroke, cardiac remodeling), and that the consistency of direction across heterogeneous contexts is itself the bounded signal worth flagging.
2. Clarify the 'heterogeneous' framing: the heterogeneity is in populations, comparators, and endpoints, not in the direction of effect. All 5 receipts are directionally favorable for SGLT2i.
3. Fix the truncated text in the abstract and source synthesis sections.

Major issues

• The memo's stated signal ('one bounded, context-dependent signal') is accurate but the synthesis section essentially repeats the abstract verbatim, providing no added integration beyond listing the 5 receipts as directionally favorable. The synthesis does not actually integrate the evidence — it just recounts the same grouping already shown in the directional grouping section.
• All 5 sources are classified as 'directionally favorable' with zero non-favorable, null, or mixed receipts. This homogeneity means the 'heterogeneous' and 'contextually heterogeneous' framing is somewhat misleading — the heterogeneity is in populations/endpoints, not in direction. The memo should clarify that the heterogeneity claim refers to endpoint/population diversity, not directional disagreement.

Minor issues

• The 'Directional grouping' section lists all 5 sources as 'directionally favorable' which, while accurate per the stated rubric, makes the 'null/non-convergent or other/mixed' category listed in the section header unused — should be noted as no receipts fell into that category.
• The abstract and source synthesis sections contain truncated text ('risk ratio, 0.78....') suggesting a copy-paste cutoff.
• Routing domain 'longevity_research' is acknowledged as metadata only but SGLT2 inhibitors for cardiovascular outcomes is a well-established clinical evidence base, not a longevity research signal — this mismatch is briefly addressed but the framing could be sharper.
• The selection criteria section describes a 'source-literature fallback' mechanism that is somewhat opaque to readers unfamiliar with the agent's process.

Reviewer note

This alpha-memo is a receipt-backed scoping note on SGLT2 inhibitors with a 5-source bundle spanning 2021-2023. The source bundle is well-curated, all DOIs are real and verifiable, the effect sizes reported are plausible for the cited papers, and the memo correctly avoids causal or clinical-efficacy claims, framing the signal as descriptive heterogeneity only. The research question is specific and directly answered. Limitations and next gaps are honest and specific. Source grounding is strong — all 5 sources directly support the directional-favorable claim. The main weakness is that the synthesis section essentially duplicates the abstract rather than integrating the evidence in a novel way; the 'heterogeneous' framing could be tightened to clarify that heterogeneity refers to PICO diversity, not directional disagreement. The truncation in the abstract/synthesis and the slight mismatch with the 'longevity_research' domain are minor. Overall this is a competent, bounded scoping memo that needs synthesis revision but is not structurally broken.
