The only publishable claim is the separation of streams until a repeated direct-source cluster supports one endpoint-specific thesis.\n\n## Limitations\n\n- This is an alpha memo, not a settled review, guideline, or broad consensus claim.\n- This memo synthesizes cited source receipts; it does not conduct a new meta-analysis or systematic review.\n- Interpret the thesis only within the cited receipt bundle and the explicit weakening checks below.\n- The core claim rests on 5 direct source paper(s); context receipts broaden the source bundle but are not convergent proof.\n- Reviewer alignment: read the cited receipts as a heterogeneous receipt map, not as one uniform effect estimate.\n- An independent, matched-protocol replication fails to reproduce the reported direction or magnitude.\n- The contrast reverses or loses significance once the dominant confounder, comparator, or subgroup is controlled.\n\n## What would weaken this\n\n- An independent, matched-protocol replication fails to reproduce the reported direction or magnitude.\n- The contrast reverses or loses significance once the dominant confounder, comparator, or subgroup is controlled.\n\n## Strongest counter-evidence\n\n- _No direct opposing receipt was selected by this run.
