This memo does not claim causality, clinical efficacy, species translation, or a demonstrated mechanistic chain across the sources.\n The signal is purely descriptive of effect-direction heterogeneity; it cannot support even a weak causal or comparative-efficacy inference, and pooling across these PICOs would be inappropriate.\n Routing domain `longevity_research` is publication-lane metadata only; the source scope here is defined by the selected epigenetic_clocks receipts.\n\n## Next gaps\n\nNo source in this fallback bundle tests human clinical endpoints.\nA stronger memo needs one matched PICO, for example: population=Common dolphins (Delphinus delphis); intervention/exposure=Hybrid epigenetic clock; comparator=dental age; outcome=Median Absolute Error (MAE).\nIf epigenetic_clocks is promoted beyond a scoping note, the next run should select sources sharing one context family rather than mixing other source context.\n","metadata":{"abstract":"This receipt-backed scoping note has one bounded signal: epigenetic_clocks shows context-dependent, not uniformly convergent associations across this 5-source primary bundle (2022-2025).
