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.
