Class D (generic keyword hygiene, GT-guarded). Two over-broad keyword->component
mappings produced ghost components:
- "kuehl"/"cool" -> Kuehlaggregat (C095) matched product variants
("Cool-Ausfuehrung") and outputs ("kuehle Glaeser"). Narrowed to cooling-UNIT
terms (kuehlaggregat, kuehlanlage, kuehler, kaeltemaschine, chiller, rueckkuehl).
- "filter" -> Absauganlage/Oelnebelabscheider (C124) matched any filter
(Laugen-/Wasser-/Oelfilter). Keep "filteranlage" only.
No pattern or GT test depends on these mappings (Kistenhub/Bremse use hand-crafted
inputs). UC-M now parses 6 plausible components (was 8 incl. the two ghosts).
Warewashing GT recall 82.4% and Kistenhub/Bremse pins unchanged.

Add ground_truth_warewashing.json + TestWarewashing_GTCoverage. The test runs
the UC-M narrative through the SAME chain as production (ParseNarrative ->
engine -> relevance + cyber filter), so keyword/gating fixes are measured on
the real hazard set, and false positives show up as "extra".
Class A (generic keyword hygiene): spuelarm/spuelfeld no longer map to library
component C004 ("Drehtisch" / rotary table) — that mislabelled the spray arm.
Keep the rotating_part tag. Removes the bogus "Drehtisch" hazard.
GT #3 baseline -> after Class A: recall 80% (unchanged), one false positive
(Drehtisch) removed. Kistenhub 97.1% and Bremse pinned mappings unchanged.
