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 C (phase-aware, generic EN ISO 14120). A contact/entanglement hazard from
a moving part is removed during NORMAL operation when the part is behind an
interlocked guard; it remains only when the guard is open (maintenance/cleaning).
- New HazardPattern.GuardableByEnclosure flag; set on HP096 (friction at
rotating surfaces) and HP101 (entanglement of hair/clothing).
- Narrative emits interlocked_enclosure for an interlocked door/hood.
- pattern_enclosure.go: suppressedByEnclosure (drop in normal-op-only contexts)
+ guardedLifecycles (re-scope to maintenance/cleaning).
- GT #3 gains the maintenance-phase entanglement/friction rows.
Generic + regression-safe: machines that do not emit interlocked_enclosure are
unaffected. GT #3 recall 80% -> 82.4%, one false positive removed (Aufwickeln).
Kistenhub 97.1% and all 26 Bremse pinned mappings 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.
