// GT #3 — commercial UNDERCOUNTER dishwasher (Winterhalter UC-M). Self-assessed
// ground truth: we can judge what a dishwasher is. The test runs the narrative
// through the SAME chain as production (ParseNarrative -> engine -> relevance
// filter + cyber-skip), so keyword/gating fixes are measured on the hazard set
// the user actually sees — not the raw pattern flood.

// Condensed UC-M limits_form narrative. Deliberately includes "Cool-Ausfuehrung"
// and "Filter" so the known false components (Kuehlaggregat, Absauganlage) are
// reproduced and visible in the baseline.
