Summary

  • preserve cuDF behavior in GFQL list+scalar concat fallback paths
  • keep bool/type probes device-side where possible to reduce host-conversion fragility
  • add cuDF list+scalar concat tests including null/empty edge cases

Validation

  • local targeted row pipeline tests passed
  • dgx-spark RAPIDS 26.02: full gfql row pipeline + parser/lowering passes
  • dgx-spark RAPIDS 25.02: new concat coverage passes; remaining instability is in existing cuDF->pandas conversion paths under constrained shared-GPU conditions
