ControlTriage composes the pipeline: a deterministic tool finding ->
controls_for(tool,cwe) [control-map LUT] -> grounded judge confirms/refutes ->
TriageOutcome { Unmapped | Confirmed([control ids]) | FalsePositive }. The LLM
enters ONLY here, as an FP filter over tool output (ZeroFalse/IRIS), never as the
detector; only judgments grounded to real code survive. Reuses the judge + core
ground gate + control-map. 3 lib tests (confirm/refute/unmapped).
