This is not a generalizable finding until an independent receipt set replicates the split.\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- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## What would weaken this\n\n- Independent receipts fail to reproduce the claimed contrast.\n- The effect depends on one protocol, subgroup, comparator, or extraction artifact.\n\n## Strongest counter-evidence\n\n- `fact_id=80697` (`A_core`) — Recreational physical activity was not associated with breast cancer recurrence (HR = 0.97, 95% CI: 0.91-1.05) Source: Postdiagnosis recreational physical activity and breast cancer prognosis: Global Cancer Update Programme (<scp>CUP</scp> Global) systematic\n\n## Next extraction\n\n- Extract independent A_core/B_context receipts that test the lead contrast directly.\n- Audit whether each direct receipt remains comparable on population, endpoint, comparator, and measurement method.\n","metadata":{"abstract":"The cited receipts show an apparent collision between a positive
