When ON, every CPCV split runs its own GA (engine default in the JAR). Institutional best practice is OFF: fixed candidate parameters evaluated across all folds with purge+embargo. Toggling here writes jenetics_overrides.json in the SQX project and exposes the exact HTTP override payload to merge into evolveSqx requests.

Invoke-RestMethod -Method Post -Uri "http://127.0.0.1:8090/sqx/jenetics/evolve" -ContentType "application/json" -Body '{"cpcvRetrain": false}'

curl -X POST "http://127.0.0.1:8090/sqx/jenetics/evolve" -H "Content-Type: application/json" -d '{"cpcvRetrain": false}'

Forces use="true" on CPCV_PASS and CPCV_WORST_PF in the SQX optimizer project XML so the GA can't rank survivors without robustness pressure. Reversible. A .bak of the XML is created on first apply.
