Phase 1 of the commercial white-goods expansion (EN ISO 10472 family). Extend
GT #3 with 8 completeness hazards a Fachmann expects but that were neither in
the GT nor previously questioned: dry-run boiler overheating, residual/stored
electrical energy, sharp-edge cut, tipping, interlock-failure, unexpected
restart, backflow (EN 1717), microbial/legionella. Enrich the UC-M narrative
with the real features so existing library patterns can fire.
Result: 4/8 auto-covered by existing patterns (dry-run, residual voltage,
tipping, interlock-failure) — recall 84% (21/25). Remaining gaps documented:
spray-arm contact (4.3), sharp-edge cut (4.6), backflow (2.3), restart (6.4).
Gate the re-surfaced CNC leak ("spanende Bearbeitung", high_temperature-only)
via dom_cnc. Kistenhub 97.1% and Bremse pinned mappings unchanged.

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.
