A 1-bit switch is domain-agnostic, yet DPT 1.001 defaulted to 'lighting', so an
"AC on/off" was classified lighting and tripped downstream checks. The domain is
now a combination: explicit name > strong domain-encoding DPT > main-group name;
a bare 1-bit GA with no signal is honestly 'unknown', never a guessed lighting.
An explicit name contradicting a STRONG DPT yields 'unknown' (a genuine conflict,
shown by explain_ga as contested), not a silent pick. Word-boundary matching so
"ac" no longer fires inside "terrace"; name terms broadened (EN+RU HVAC incl.
ac/a-c/air-conditioner, RGB/colour lighting).
check_policy taxonomy-outlier now flags only misplaced ACTUATORS (lighting/
shutter/hvac); sensors, scene links, thresholds and timeout params are the
cross-cutting GAs they are. HA generator still emits a switch for a now-HVAC
simple on/off, so no device is dropped.
Verified on 3 real projects: every AC on/off is HVAC; outlier noise fell demo
11->2, Minsk 31->6, Razdory 200->57. tests/test_domain_classifier.py (13/13 green).

Three independent reviewers (two external councils + a field integrator) asked for
the same thing: the enriched model mixes ETS facts, DPT structure and name
heuristics, and downstream tools treat it almost as fact. explain_ga makes the
reasoning auditable per GA — evidence per decision with a confidence tier
(authoritative ETS Function > structural DPT > heuristic name), the status-pairing
method, and CONFLICTS (name 'AC' vs DPT 'lighting' -> contested), the silent-
misclassification hotspot. Additive, read-only, no core-model change. Full suite green.
